A five-year retrospective and one-year prospective studies of gastrointestinal (GIT) helminths was carried out in humans and dogs in Makurdi, Nigeria. Data from 534 individuals presented at the Federal Medical Centre (FMC) and 103 faecal samples from dogs at the Veterinary Teaching Hospital (VTH), University of Agriculture, Makurdi from 2007 to 2014 were used. The overall prevalence of zoonotic GIT helminths in humans was 76.21% (407/534) and 56.31% (58/103) in dogs. The differences in the prevalences in humans based on sex,ethnicity and age were not statistically significant (χ2 , P< 0.05). However, the test of individual factor (coefficient) on GIT helminthes in humans showed that hookworms prevalence was dependent on age (P = 0.001), Ascaris lumbricoides was dependent on ethnicity and age (P = 0.000 and 0.005), Taenia spp. prevalence was dependent on age and sex (P = 0.007 and 0.005), and Strongyloides stercoralis prevalence was dependent on age (P = 0.04). The prevalence in dogs depended on age and breed (χ2 ,P < 0.05) but not on sex (χ2 ,P > 0.05). Hookworms, Taenia spp and Trichuris vulpisoccurred in humans and dogs. Hookworms were the most common helminth of both humans and dogs. Individual factor (coefficient) on the effect of risk factors on specific helminths is essential in understanding the epidemiology of each helminth. Attention should be paid to control measures in man anddogs.

Bacteriology of otitis media among patients attending generaltheijes
Otitis media is the inflammation of the middle ear and has a worldwide distribution, particularly among children. A total of 68 patients between the ages 0-42 years who presented with sign and symptoms of otitis media at Bichi general hospital were enrolled for this study. Middle ear discharge were collected, processed and bacterial isolates identified using standard microbiological techniques. Disc susceptibility tests were performed on bacterial isolates. Results indicated that there was a high frequency of occurrence of bacteria incriminated in otitis media in the 0-5 and 6-11 year age groups in the two sexes. Male patients in the two age groups were more infected than the female counterparts. The sensitivity pattern obtained in this study show a progressive increase in the emergence of strains that are resistant to many chemotherapeutic agents. Drug resistance among bacterial isolates is a common phenomenon placing challenge to both medical practitioners and genetic scientists. A routine check on sensitivity patterns among these pathogens is vital so as to regulate the prescription measure to be employed.

Clinical Manifestations of Plasmodium bergheiANKA Infection in Juvenile Mice:...AI Publications
Malaria is an important health and development challenge in Africa, Animalmodels most particularly mice, have long been employedto study malaria pathogenesis. Clinical manifestations due to Plasmodium bergheiANKA infection in juvenile mice as a model for understanding the complications ofcongenital malaria in neonates.Forty-five juvenile mice (5-7 days old) were acquired from University College Hospital, Ibadan and injected with 2 x 107 (0.2ml) Plasmodium berghei ANKA parasitized red blood cells (PRBCs). Mice were transported to the study site, kept in well ventilated cages and fed daily with a balanced ration. Every day after post-P. berghei infection, mice were monitored for mortality. Clinical manifestations ofexperimental cerebral malaria (ECM) was assessed and confirmed if at leastruffled fur, hunching, wobbly gait, limb paralysis, convulsions, or coma was observed. Each sign was given a score of 1. Animals with scores ≥4 were considered to have severe ECM.20 (44%) micewerelost due to natural cause (i.e. stress) at day 2 of the experiment. Between day 4 and 9, 25 (56%) of the studymice presented clinical signs of ECM which includes; ruffled fur 25(100%), hunching 21 (84%), wobbly gait 17 (68%), limb paralysis 20 (80%), convulsions 25 (100%) and subsequently died. Survival rate and severity of ECM in the mice differs, 22 (88.0%) had severe ECM and 3(12.0%) had mild ECM.This study has shown that parasite establishment and malaria complications can manifest as early as 4 days’postP. berghei infection in 5-7 days old mice.

Delay of Geo/Geo/1 N-limited Nonstop Forwarding Queuetheijes
Nonstop forwarding is designed to minimize packet loss when a management system fails to function. A system with non-stop forwarding can continue to forward some packets even in the event of a processor failure. We consider a Geo/Geo/1 N-limited nonstop forwarding queue. In the queueing system, when the server breaks down, up to customers can be serviced during the repair time.The delay distribution of customers is given by matrix geometric analysis.
Queue with Breakdowns and Interrupted Repairstheijes
This paper considers a queue, consisting of a Poisson input stream and a server. The server is subject to breakdowns. The times to failure of the server follows exponential distribution. The failed server requires repair at a facility, which has an unreliable repair crew. The repair times of the failed server follows exponential distribution, but the repair crew also subjects to breakdown when it is repairing. The times to failure of the repair crew is also assumed to be exponentially distributed. This paper obtains the steady-state performance of the queuewith server breakdowns and interrupted repairs.
Analytical Execution of Dynamic Routing Protocols For Video Conferencing Appl...theijes
In modern network communications, Routing protocols are getting an important function for the user data path that are responsible for controlling the routers to communicate together and forward packets by routers over the best trip path from a base node to a destination one. Dynamic routing protocols represented by RIP, OSPF and EIGRP are explained here for addressing various networks with different traffic environments. In this paper, the performance of these protocols are estimating with many factors like convergence activity and duration, average throughput, network end-to-end delay, Point-to-Point Utilization over the simulation based on OPNET academic version. From Simulation results, EIGRP have a fastest time convergence compared with other topologies of networks are confirmed and the OSPF has the highest Point-to-Point Utilization in the network followed by EIGRP then RIP. So, there is an attempt for finding out which protocols are suitable for the networks and from analyses to understand the role of the routing protocols in different network scenarios
Concepts and Trends on E -Learning in Romaniatheijes
E-Learning systems analysis appears to be simple if we take into consideration some of the approaches employed by researchers so far. But the dynamics of e-Learning requires caution. For more than seven years there have been discussions about a new generation of e-Learning, namely e-Learning 2.0. The e-Learning market is estimated to bring revenue of U.S. $ 56.2 billion in 2013 according to Certifyme.net, the industry leader in online training, and this amount is projected to double its value by the end of 2015. In Romania, a team of researchers from the Centre for Development and Innovation in Education – has been using techniques aimed at identifying and classifying theoretical and practical approaches to training and education. If we consider the mission of this non-governmental organization (with no political affiliation) to promote the principles and values in education through innovative technologies and approaches (such as conducting programs and e-Learning projects, developing curricula, education for democratic citizenship, lifelong learning and continuous training of teachers) then we can rely on the experience of the organization and the seriousness with which the foundation is involved in defining and e-Learning phenomenon.

A total of 240 patients undergoing conventional radiology in four hospitals of the city were considered. The device used to measure De and DAP values is a DAP-meter, model Diamentor M4 KDK and of type 11017. The DRLs in terms of De and DAP values were determined by applying the 75th percentile method. These values were compared to DRLs values obtained in other countries and to those recommended by international institutions. The values of De measured are encouraging, however for the DAP; many efforts are needed to be made to reduce the DRLs values
A Study of the Root Causes of High Failure Rate of Distribution Transformer -...theijes
A distribution transformer is one of major electrical equipment that links the power utility and power consumers. It is what enables the power utility to supply electricity to consumers. In recent time, there has been an upsurge of distribution transformers premature failure before reaching the desired and designed service life. Consequently, the power utility has been incurring huge economical losses in replacing the faulty transformers or repairing them. On the other hand, failure of transformer inconveniencies power end users by interrupting the power supplies for prolonged period of time before the faulty transformer is replaced. In this paper, an effort is made to investigate the root causes of premature failure of distribution transformers. Research has revealed that line surges and switching transients are among the main causes of the transformers failures as this accelerates deterioration of insulation materials. This has been aggravated by lack of lightning arrestors and vandalism of low voltage and high voltage earthing systems. It is also noted that a transformer is usually ‘killed’ by unusual stresses that usually break down its weak insulation and hence leading to reduced transformer life. Use of concrete poles with earth wire appended is proposed to deter vandalism of earthing wire. In addition, proper fuse grading, installation of High Voltage (HV) expulsion fuses and regular Operational and Maintenance (O&M) has been recommended to reduce the premature failure of distribution transformers.

Bituminous Pavement Recycling – Effective Utilization of Depleting Non-Renewa...theijes
Bituminous pavement recycling is an effective and worldwide proven technique of conserving Energy, Environment and Economy while ensuring maintenance and preservation of roadway network. In the pavement recycling process, the materials from deteriorated pavements known as Reclaimed Asphalt Pavement (RAP), is partially or fully reused in fresh construction. The concept of RAP lies in restoring the physico-chemical properties of the aged bitumen to its original and at the same time to enhance the mechanical properties and strength of the aged binder. This paper gives a brief overview of various recycling methods of bituminous pavement including (1) Hot mix recycling, (3) Hot-in-place recycling, (3) Cold central plant recycling, (4) Coldin-place recycling, and (5) Full depth reclamation, their advantages, selection considerations, review of mix design procedure, unresolved issues related to their use and future scope in Indian context.
The Effect of Arm Stiffness on the Elasto-Kinematic Properties of Single-Axle...theijes
The paper is focused on the stiffness analysis of the longitudinal arm of single-axle suspension on elastokinematic behaviour of the vehicle axle which is highly important when considering the handling characteristics related tovehicle safety.The elasto-kinematic behaviour of the axle determines the course of the geometrical parameters of wheel suspension, the toe angle and camber as the function of wheel movement during force loading. This paper presents the complex MBS (Multi-Body Simulation)model of the wheel suspension with nonlinear characteristics of rubber-metal bushings. The model also comprises force elements such as springs, shock absorbers, stops and the transverse stabilizer. The model of flexible arm is implemented in the MBS model using the Craig-Bampton method, which represents a flexible body based on the synthesis of its own modal shapes. Subsequently,elasto-kinematic simulations are performed with the help ofthe computational system Hyperwork. The computational part of the paper presents the results of the elasto-kinematic behaviour of wheel axle for the flexible arm with different sheet metal thicknesses (2, 3 and 4 mm) and different materials (steel and aluminium alloy AlSi7Mg). Individual calculation models are compared to each other and also to the model of suspension with therigidarm. Elasto-kinematic analyses are also validated by the measurement inthe testing stage.
Turbofan Engine Modelling and Control Design using Linear Quadratic Regulator...theijes
There are many applications in which gas turbine engine is used today, including aircraft propulsion for both commercial and military purposes, and power generation and in all these Control systems technology has played a fundamental role in enhancing performance. Modelling plays a significant role in the development of the entire engine system performance. This paper investigated Linear Quadratic Regulator (LQR) model-based control method to obtain estimates of performance parameters. The main control variable selected is the fuel flow to control the rotational speed of high-pressure spool speed of the turbofan engine. Firstly a suitable mathematical model of the engine is developed in MATLAB Simulink environment with both the intercomponent volume and the constant mass flow methods used. Equations of the mass flow rate and the torque balance are incorporated in the steady state and dynamic state of the thermodynamic engine model. This represents the engine model by a set of first-order differential and algebraic equations and a linearized model is extracted for the analysis and design of a controller by LQR. It is demonstrated that LQR based controllers can perform better than conventional PID controllers. The settling time, rise time and maximum overshoot for LQR based controller are all less than those for PID based controller. The input also changes more accurately for LQR than the PID controller compared.

Pilot plant composed of fabric filters integrated with the decentralized treatment plant ZECUwas tested for its ability to remove the suspended solids and organic matters presented as TSS, CODt and CODs from wastewater. The filters were made from scrim polyester non-woven fabrics and were tested on gravity driven pressure. The investigation was executed on two phases. In the first phase; the flux rates were changed from 3.5-15 L/m2 /hr and the differential hydraulic head was 1.5 m, average TSS, CODt and CODs effluent concentrations 40 mg/l, 177 mg/l and 119 mg/l respectively. In the second phase the differential hydraulic head was changed to be 2.5 m, average TSS, CODt and CODs effluent concentrations were 43.6 mg/l, 133.7 mg/l and 105.3 mg/l respectively. The potential removal mechanism for the suspended solids by fabric filters is straining or sieving by filter pores. The potential removal mechanism for dissolved organic matters is dynamic membrane layer formed on the fabric filters surface and was able to remove soluble organic matters with CODs average removal efficiencies of 21.25% and 18.9%inphase (1) andphase (2) respectively.

In high schools of Viet Nam, teaching calculus includes the knowledge of the real function with a real variable. A mathematics educator in France, Artigue (1996) has shown that the methods and approximate techniques are the centers of the major problems (including number approximation and function approximation...) in calculus. However, in teaching mathematics in Vietnam, the problems of approximation almost do not appear. With the task of training mathematics teachers in high schools under the new orientations, we present a part of our research with the goal of improving the contents and methods of teacher training

AI transmission risks: Analysis of biosecurity measures and contact structureHarm Kiezebrink
Contacts between people, equipment and vehicles prior and during outbreak situations are critical to determine the possible source of infection of a farm. Hired laborers are known to play a big role in interconnecting farms. Once a farm is infected, culling entire flock is the only option to prevent further spreading with devastating consequences for the industry.
In this paper, based on the HPAI outbreak in Holland 2003, the researchers found that 32 farms hired external labor of which seven accessed other poultry on the same day.
However, they were not the only ‘connectors’ as some (twelve) farmers also reported themselves helping on other poultry farms.
Furthermore, 27 farms had family members visiting poultry or poultry-related businesses of which nine entered poultry houses during those visits. The other enhancing factor of farm interconnections was the reported ownership of multiple locations for ten of the interviewed farms and the reported on-premises sale of farm products on one pullet and eight layer farms.
Also worth mentioning is the practice of a multiple age system reported on eight of the interviewed farms as this may increase the risk of infecting remaining birds when off-premises poultry movements occur.
AI viruses may be introduced into poultry from reservoirs such as aquatic wild birds but the mechanisms of their subsequent spread are partially unclear. Transmission of the virus through movements of humans (visitors, servicemen and farm personnel), vectors (wild birds, rodents, insects), air- (and dust-) related routes and other fomites (e.g., delivery trucks, visitors’ clothes and farm equipment) have all been hypothesized.
It is therefore hypothesized that the risk of introducing the virus to a farm is determined by the farm’s neighborhood characteristics, contact structure and its biosecurity practices.
On the one hand, neighborhood characteristics include factors such as the presence of water bodies (accessed by wild birds), the density of poultry farms (together with the number and type of birds on these farms) and poultry-related businesses and the road network. The use of manure in the farm’s vicinity is also deemed to be risky.
On the other hand, contact structure risk factors include the nature and frequency of farm visits. Therefore, a detailed analysis of the contact structure, including neighborhood risks, and biosecurity practices across different types of poultry farms and poultry-related businesses helps the improvement of intervention strategies, biosecurity protocols and adherence to these, as well as contact tracing protocols.
Farmers’ perception of visitor- and neighborhood-associated risks of virus spread is also important due to its relevance to adherence with biosecurity protocols, to contact tracing and to communicating advice to them.

Although the helminth parasites of domestic hogs are well documented worldwide, no information is available about the digestive and pulmonary helminth infections of wild boar in Morocco. The lungs of 33 wild boars (Sus scrofa barbarus) (19 females and 14 males) from four area of El Hajeb province (Middle Atlas) hunted officially for wildlife damage control, from October 2014 to March 2015 were examined for lung nematodes. Twenty eight out of 33 wild baors, (84.4%) were positive for three species of Metastrongylus and their prevalence was as follows: Metastrongylus pudendotectus (84.4%), Metastrongylus confusus (72.7%) and Metastrongylus salmi (51.5%). In most cases, multi-species infection was observed. Prevalence and infection intensity were found greater in juvenile females less than 1 year old than in adults and males. Prevalence and intensity of infection were higher in wild boars collected from range lands and forest than in wild boars collected in the cultivate area. Further studies are needed to understand the factors structuring Metstrongylidae communites
Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Per...Agriculture Journal IJOEAR
Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick's species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.
Study of the Seroprevalence of Anti-Leptospirosis Antibodies in Subjects in T...IIJSRJournal
Leptospirosis is a tropical and subtropical zoonotic disease culminating as a serious public health problem worldwide, apparently existing as co-infections with various other unrelated diseases, such as malaria. It is caused by spiral bacteria and the main vectors of which are rodents. These bacteria have various survival mechanisms in the environment allowing them to carry out their infectious cycle within their host organisms. The pathophysiological mechanisms pertaining to leptospirosis is still not understood in full and mis or underdiagnosed.
A cross-sectional descriptive study was carried out in three different localities in Niamey where respondents were screened for to demonstrate transmission to humans. Indirect ELISA method as a laboratory diagnostic or screening toll is used by utilizing leptospiral-specific IgG from serum samples of the respondents.
Results from the study showed that 11 people are found to be positive for leptospirosis (with a seroprevalence of 2.75%) with a strong tendency in the slaughterhouse workers which presents a fairly high risk compared to the other localities of the study. Indeed, the different areas/localities of this pilot study do not present the same level of risk because they are not subject to the same risk associated factors. In this vein, we have 87.6% of population exposed to the presence of rats, 48% are in contact with animals, 38.6% live in homes near water and 12.9% go swimming.
This study made it possible, on the one hand, to highlight the transmission of leptospirosis from animals to humans and, on the other hand, to draw attention to the involvement of the various identified risk factors.

Implications of Robotic Walkway Cleaning for Hoof Disorders in Dairy CattleIJERA Editor
Infectious hoof disorders are a serious challenge for dairy production since they cause pain and discomfort in cows and can compromise the competitiveness of dairy farming. Robot scrapers are capable of frequently removing liquid manure from slatted floors and can contribute to improved hygiene of walkways. The aim of this study was to observe the implications of the robotic cleaning of walking areas for infectious hoof disorders in dairy cattle. A large herd ranging from 1,247 to 1,328 Holstein Friesian cows was monitored in two six-month periods in 2012 and in 2013. All animals were housed in a cubicle housing system with slatted floors in which walkways were cleaned using robot scrapers in 2013 but not in 2012. Statistical analysis was carried out with either the Chi-square test or the Fisher’s exact test in R. Results indicated that the presence of infectious hoof disorders declined after robot scrapers were used for the cleaning of walkways. While in the first investigation period 648 animals suffered from infectious hoof diseases, in the second period only 340 animals were affected. This study stresses the significance of environmental hygiene to improve hoof health in dairy cattle.
ABSTRACT- This study was an attempt to estimate the prevalence of fungal isolates in superficial mycoses cases attending IPD and OPD of IIMS&R, Lucknow, Uttar Pradesh.A prospective study over a period of six (6) months was conducted from January 2015 to June 2015.The suspected cases of superficial mycoses were subjected to mycological examination with direct microscopy using 10%-40% KOH depending on the types of samples (skin, nail, hair) processed and culture on Sabouraud’s dextrose agar with chloramphenicol and cycloheximide (SDCCA) and also on Potato dextrose agar (PDA) medium. Causative agents were identified macroscopically and microscopically from the growth obtained on SDCCA and PDA. Direct microscopy revealed fungal elements in 78 (66.1%) cases whereas 54 (45.7%) were positive on culture. Out of 54 (45.7%) culture positive samples 6 (15%) were negative on microscopy (KOH mount). Tineacorporis 38 (32.2%) was the most common clinical types and male is to female ratio in relation to clinical types was 2.2:1. Commonest age group affected were 21-30 years with 41 (34.7%) cases. Males were predominantly affected 41 (75.9%) and male to female ratio being 3.1:1. 60% of the patients came from the rural background. College students formed a major chunk of the cases 29 (24.6%) followed by housewives 18 (15.3%) and unskilled workers 16 (13.6%). Trichophyton mentagrophytes 20 (37%) was the predominat isolate followed by T. tonsurans15 (27.7%), T. rubrum3 (5.5%), M. audouinii 3 (5.5%) and T. schoenleinii 2 (3.7%) with no Epidermophyton species. A non-pigmented variant of T. rubrum was identified in this study. Both SDCCA and PDA were found equally effective in isolating fungal isolates from clinical samples in our study. We are reporting change in frequency of dermatophytes isolated from superficial mycoses cases in our region.
Key words- Superficial mycoses, Non-pigmented variants, Dermatophytes
Endemic canine rabies is a reemerging neglected zoonosis often underestimated in Kenya but remains a public health and economic burden to the rural poor. Understanding the transmission dynamics and distribution of dog bites over specified time period can assist in assessment of risk factors, design of interventions to exposure and the estimation of rabies burden
This was a prospective cross sectional hospital based study included 117 patients with a definitive history of snake bite and clinical features consistent with the pres¬ence of fang marks at the emergency department, Gadarif Hospital, Eastern Sudan from 1st January 2015 to 1st January 2016 to identify the epidemiological factors of snake bite. The majority of these 117 patients were adult (86.3%) and male gender constituted 85.4%. Most of the patients were of rural residence (65.8%) and were involved in farming related activities (68.3%). A relatively high proportion of snake bite episodes happened in the afternoon times (53.9%) and half of the cases were reported during August (18%) and November. (12.8%). Lower limbs were involved in maximum number of the cases (83.7%). The reported systemic reaction included: swelling (100%), sweating (100%), hypotension (54.7%), nausea (51.%), vomiting (47.8%), local bleeding (13.6%), hymoptysis (1.7%) and neurotoxic symptoms (0.8%). In this study, there were ten (8.5%) deaths; 7 had grade 3 and the other three patients had grade 4 envenomation. In conclusion Snake bites is a real medical threat in Eastern Sudan; thus, it is very important to educate the native people to increase awareness about the risk of snake bites in particular among male, farmers and during the period from August to November.

Hepatic and Rumenal Worms Infestations of Cattle in Vina Division (Adamawa – ...AI Publications
The main objective of this work is to describe a preliminary epidemiological account of major hepatic and rumenal distome worms of cattle in Vina Division, Adamawa Region of Cameroon. A total of 1361 cattle dung specimens and 450 blood samples were collected between April 2018 and March 2019 in 06 subdivisions within Vina Division. The dung and blood samples were placed in a cooler. The cooler was immediately transported to the medical and veterinary laboratory of Special Mission of tsetse fly Eradication where samples were kept cold at +4°C for at most 48 hours. The qualitative method of concentration of worm eggs by simple sedimentation was performed.Blood parameters were measured using a haematology automated system. Of the 1361 cattle dung specimens examined, 424 presented distome eggs giving a prevalence of 31.15 %.These were Fasciola gigantica, Paramphistomum daubneyi and Dicrocoelium hopes eggs.All cattle age groups were infected by worms. In terms of prevalence, medium cattle were found to be the most infected. In lean cattle the parasitic loads of F. gigantic and D. hopes were high and then decreased as the health of the animals improved. All cattle breeds were infected by at least one of the worm species. Bokolo and Djafoun were most infected by F. gigantica, while Holstein and Aku were more influence by P. daubneyi. Goudali breed is the one that has undergone the least parasitic pressure. Male cattle were more infected than females, but females exhibited higher mean intensity of infestation. Older cattle were more susceptible to F. gigantic and D. hopes infection while Adults were more infected by P. daubneyi. Whatever the parasite considered, parasitic load progressively increased with the age of the cattle. The number of cattle infected by P. daubneyi and D. hopeswas greater in the rainy season unlike F. gigantic infection which was more recurrent in the dry season. Mbe locality had a high prevalence of F. gigantica and P. daubneyi. However, Ngaoundere 1, 2 and 3 presented the highest mean intensities for all worm species. Prevalence and mean intensities of cattle have been more important in extensive livestock status. All the worms were encountered all year round, except for November and December 2018 where D. hopes was absent. Polyparasitic cases were observed. Nevertheless, bispecifics associations were most frequent. Mean Corpuscular Volume, Platelet Concentrations, Mean Corpuscular Haemoglobin, Total Leucocytes Count and Granulocytes mean values were higher in cattle with significant parasitic loads while Total Erythrocyte Count and Packed Cell Volume were low. Today, it is well established that distomatoses represent one of the major parasitoses of cattle in Vina Division of Cameroon.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric

--------------------------------------------------------ABSTRACT-------------------------------------------------------------
A five-year retrospective and one-year prospective studies of gastrointestinal (GIT) helminths was carried out in
humans and dogs in Makurdi, Nigeria. Data from 534 individuals presented at the Federal Medical Centre
(FMC) and 103 faecal samples from dogs at the Veterinary Teaching Hospital (VTH), University of Agriculture,
Makurdi from 2007 to 2014 were used. The overall prevalence of zoonotic GIT helminths in humans was
76.21% (407/534) and 56.31% (58/103) in dogs. The differences in the prevalences in humans based on
sex,ethnicity and age were not statistically significant (χ2
, P< 0.05). However, the test of individual factor
(coefficient) on GIT helminthes in humans showed that hookworms prevalence was dependent on age (P =
0.001), Ascaris lumbricoides was dependent on ethnicity and age (P = 0.000 and 0.005), Taenia spp. prevalence
was dependent on age and sex (P = 0.007 and 0.005), and Strongyloides stercoralis prevalence was dependent
on age (P = 0.04). The prevalence in dogs depended on age and breed (χ2
,P < 0.05) but not on sex (χ2
,P >
0.05). Hookworms, Taenia spp and Trichuris vulpisoccurred in humans and dogs. Hookworms were the most
common helminth of both humans and dogs. Individual factor (coefficient) on the effect of risk factors on
specific helminths is essential in understanding the epidemiology of each helminth. Attention should be paid to
control measures in man anddogs.

I. INTRODUCTION
A large number of diseases that are endemic in sub-Saharan Africa have been overlooked even by local health
authorities who have along with international health systems, made these diseases to be labelled as neglected
tropical diseases (NTD) (Hotez et al., 2008; Hotez and Kamath, 2009). A vast majority of these diseases affect
mostly the very poor and are often co -endemic with malaria and HIV/AIDS (Hotez, 2011). The typical
abandoned diseases are zoonotic gastro-intestinal, soil-transmitted helminths infections (Hotez et al., 2007,
2008).
These infections are prevalent in Nigeria, especially in children living where adequate water and sanitation
facilities are lacking (Abah and Arene, 2015, Odinaka et al., 2015). It has been observed that children living
under such conditions can be chronically infected with several species of helminths (Hotez et al., 2008; Usip
and Mathew, 2015). Chronic helminth infections result in anaemia, stunted growth, under-nutrition, reduced
work efficiency and poor cognitive development (long-term disability and poverty) (Hotez et al., 2007, 2008).
This ignored morbidities enhance malaria (Mwangi et al., 2006).
The high prevalence rates haveled to the estimation of the worm burden using prevalence, (Usip and Matthew,
2015), instead of the classic measure by eggs per gram (EPG) of faeces and its association with morbidity
(Hotez et al., 2008). Dogs have been implicated in the transmission of some human GIT heminths (Bownan et
al., 2010; Deplazes et al., 2011; Ogbolu et al., 2011; Traversa et al., 2014). Contamination of the
environmentdue to poor sanitary facilities and a high dog population prompted the study which should remind
health authorities about the ever present status of these neglected diseases in Nigeria.
II. MATERIALS AND METHODS
Retrospective and prospective studies of zoonotic GIT helminthes of humans and dogs were carried out at The
Federal Medical Center (FMC) and Veterinary Teaching Hospital, (VHT), University of Agriculture, Makurdi,
respectively. The case-control study involved retrieving data from the general out-patient department (GOPD),
the medical records archive and laboratory sections of the hospital from January, 2007 to December 2012. The
prospective study was carried out by systematically collecting faecal samples per rectum from dogs presented at
the VTH Makurdi every Tuesday and Thursday from April 2013 to March 2014. The faecal samples were
analysed using the salt floation technique (Zajac and Conboy, 2012).

Age, sex, ethnic group and type of parasite were the parameters used for retrieving data in the retrospective
study while age, sex and breed were used in the prospective study. A sample size of 310 was arrived at using the
method of Thrushfield (1995). Ethical clearance to conduct the study was obtained from the Ethical Committee,
FMC Makurdi. The data generated from the study was analysed using the Statistical Package for Social Sciences
(SPSS) for windows version 20.0. The Chi-square ((χ2
) was employed to test for association between variables.
Chi-square test of model coefficient for individual helminths was used to ascertain whether the prevalence of
each helminth depended on specific risk factors. Where dependence was demonstrated, the test of individual
factor coefficient was carried out to determine the significance of each risk factor to the prevalence of specific
helminths. In all analyses statistical significance was taken to be at (p < 0.05).
III. RESULTS
A total of 534 cases were retrieved for the five years retrospective study. The overall prevalence of zoonotic
GIT helminths in humans at the FMC was 76.21% (407/534). The year 2009 had the highest prevalence rate of
100% (Table 1). The distribution of the prevalence based on sex was 57.5% (234/407) for males and 42.5%
(173/407) for females. The difference was not statistically significant (p.>0.05). The 11-20 age group had the
highest prevalence rate of 86.7% (91/105). The difference was not significant (p>0.05).The distribution based
on ethnicity was 58.96% (24/407) Tiv, 15.72% (64/407) Idoma and 25.3% (103/407) other Nigerian ethnic
groups. The difference was not significant (p>0.05) (Table 2).

However, the Chi-square test of model coefficient for individual helminths showed that the prevalence of
hookworms, Ascaris lumbricoides, Taenia spp. and Strongyloides stercoralis in humans depended on risk
factors (Table 3). The test of individual factor (coefficient) on GIT helminths showed that the prevalence of
hookworms was dependent on age (p=0.001), but independent of sex and ethnicity (p=0.140 and 0.954)
respectively. Ascaris lumbricoides prevalence was dependent on ethnicity and age (p=0.000 and 0.005) but
independent of sex (p=0.545). Taenia spp. prevalence was dependent on age and sex (p=0.007 and 0.005) but
not ethnicity (p=0.366). Strongyloides stercoralis prevalence was dependent on age (p=0.004) but not sex or
ethnicity (P=0.05 and 0.366) (Table 4).

IV. DISCUSSION
The study recorded high prevalence rates of GIT helminths in both humans and dogs at 76% and 56 %
respectively. The high prevalence in humans has confirmed the endemic nature and the burden of these
infections in Makurdi, Nigeria, as has been reported (Hotez et al, 2011). The prevalence rate in humans was
higher than reports by Odinaka et al. (2015) and Abah and Arene (2015) from Imo and Rivers States
respectively. The prevalence in dogs has demonstrated that dogs can potentially contaminate the environment
leading to transmission to humans. The prevalence rate in dogs was higher than that reported by Onyeabor
(2014) in Umuahia, Abia State but similar to the report by Kutdang et al. (2010) in Jos, Plateau State.
Chi-square analysis of the entire data from the retrospective study showed that sex, ethnicity and age were not
significant factors on the prevalence (p>0.05). However, the test of individual factor (coefficient) on specific
GIT helminths showed that hookworms, Ascaris lumbricoides, Taenia spp and Strongyloides stercolaris

prevalence depended one age. The dependence on age is consistent with the epidemiology of GIT soil-
transmitted helminthes in the tropics (Hotez et al., 2008) and demonstrates the need to carry out studies on
individual helminthes infections in other to bring out the effects of various factors. The dependence on age
maybe because children have more access to the soil from playing and observe less hygienic practices. Ascaris
lumbricoides prevalence was also shown to be statistically dependent on ethnicity (p>0.05). Sampling bias on
children of poor Tiv ethnic group could have accounted for this since the FMC is in Makurdi where children of
poor Tiv ethnic group have access.
The finding by the study that hookworms, ascariasis, trichuriasis, schistosomiasis and taeniasis were identified
in humans with hookworms being the most prevalent underlines the position of Nigeria as the leading sub-
Saharan African country with the greatest burden of disease from soil transmitted helminths as reported by
Hotez and Karmath, (2009), and Hotez, (2011). The high prevalence may be due to the moist sandy nature of
Makurdi soils which reportedly favours larval transmission and the high population of dogs. (Omudu et
al.,2010; Hotez, 2011; Babamale etal., 2015; Babamale and Ogbomoiko, 2016) which supports zoonotic
transmission. The helminths identified were similar to the ones in dogs and from other reports. (Hotez etal.,
2007; Hotez, 2011; Babamale etal., 2015; Babamale and Ogbomoiko, 2016), and were zoonotic in nature as
reported by Abere et al (2013).
The study has reported a high prevalence of similar GIT helminths in man and dogs with hookworms being the
most prevalent infection.in Makurdi, Nigeria. We therefore concluded that dogs have a significant potential in
the transmission of the infections to humans. Also, individual studies of different GIT helminths are necessary
to elucidate each helminths epidemiology. Control of the infections in dogs is essential to reducing the burden of
infections in man. We recommend large scale annual mass de-worming campaigns and echo Hotez (2011) call
of linking neglected tropical disease to malaria and HIV/AIDS initiatives in Nigeria.
