The Forelimb of the Grasscutter (Thryonomysswinderianus) was studied using 12 adult rats of both sexes with mean weights of 5167±0.2023kg and 0.8167±0.1276kg for male and female respectively. Correlation coefficient between length of each bone segment and weight of each animal revealed statistical significance (P < 0.05) in all bone segments except the manus when both sexes (n = 12) were considered signifying a positive relationship between weight of the animal and its bone size. The average total number of bones in the forelimb of the rat is 96 bones. Sexual dimorphism was not noticed. The bones of the forelimb revealed significant differences and similarities in morphology to that of other rodents and domestic animals. The Scapula presented a prominent triangular shaped metacromion and acromion process, the Humerus presented well defined head and distinct deltoid tuberosity protruding from the midshaft. The ulna and radius fuses proximally and distally leaving an expansive interosseus space. There were 8 irregularly shaped carpal bones arranged 3 proximally and 5 distally. Metacarpal and digital bones are 5 on each forelimb with the first and fifth greatly reduced with each digit presenting 3 phalanges.

The study demonstrated that eight weeks after bilateral ovariectomy in female white Wistar rats, develops endothelial dysfunction of bone microvasculature and deterioration of regional blood flow in the bone, leading to the emergence of generalized osteoporosis. Nanoparticulated forms of Losartan and Nanoparticulated forms of Resveratrol, possessing endothelial protective action, effectively prevent the reduction of regional microcirculation in bone tissue, keeping it at the level of intact rats. It is allowed to maintain an adequate level of bone remodeling processes, which manifested by slowing the thinning of bone trabeculae.

The present study was designed to investigate the effects of varying intensities of noise stress onto the body and adrenal gland weight (absolute) of 17 weeks old (291–296) gram (g) Wistar rat. Animals were exposed to varying intensity of noise, i.e., 60 dB (Decibel), 80 dB, 100 dB, 120 dB, and 140 dB for 1 h (h)/day for 30 days. The dose of different noise intensities was delivered through a special fabricated noise chamber which had provided all daily needs of animal-like oxygen, food, and water. Food and water consumption behavior was recorded on 1st, 14th, and 29th days and body weight change recorded on 1st, 15th, and 30th days after the exposure of noise stress. Absolute adrenal glands weight was recorded on the 30th day. The results of the present study showed that the food, water consumption behavior, and body weight (g) of the experimental group EG1 (60 dB), EG2 (80 dB), EG3 (100 dB), EG4 (120 dB), and EG5 (140 dB) were found to be significantly (P < 0.001) decreased during 1st–14th days and during 15th–30th days a recovery which were observed in food, water consumption, and in body weight of the EG1 (60 dB), EG2 (80 dB), and EG3 (100 dB). A percentage (%) decrease was found, i.e., 0.76, 0.37, 3.87, 25.89, and 30.06% in body weight of EG1 (60 dB), EG2 (80 dB), EG3 (100 dB), EG4 (120 dB), and EG5 (140 dB) experimental groups, respectively.

Population morphometry including population demography, size group distribution, length weight relationship and sex ratio of an important freshwater fish, Colisafasciata was studied which collected fromJessore and Jhenaidah districts in Bangladesh during May, 2014 to April, 2015. Random samples of 201 individuals (108males and 93 females) were collected from different fish markets in Jessore (Monirampur, Borobazar, Chowgasa) and Jhenaidah (Mohespur, Barobazar, Kotchandpur) districst. The mean size of the specimen was recorded 65.08 ±14.32 mm in length and 7.43 ±3.09 g in body weight. Females were found little smaller than males. The specimens were larger in winter than summer and monsoon season. But in monsoon season the females were larger than males. The maximum length of the specimen collected from Jhenaidah district was smaller compare to the specimen of Jessore district. Most of the population (29%) was observed under 55-64 mm size class. Linear relationship was obtained between the log length (mm) and log weight (g) of the species in respects of sexes, seasons, and districts. The allometric coefficient ‘b’ of the relationship indicated negative allometric growth of the species as ‘b’ value was less than 3. The overall sex ratio (male: female=1:0.86)showed significant difference from the expected value 1:1. Overall males showed non-significant over females (χ2 =1.119) in all season of both districts but in November males showed the significant (P<0.01) dominance over females. However, the findings of the present study have helped us to understand more about the species is the prerequisites in fishery management strategy and culture system.

In Benin, chilli pepper is a widely consumed as vegetable whose production requires the use of performant varieties. This work assessed, at Parakou and Malanville, the performance of six F1 hybrids of chilli including five imported (Laali, Laser, Nandi, Kranti, Nandita) and one local (De cayenne), in completely randomized block design at four replications and 15 plants per elementary plot. Agro-morphological data were collected and submitted to analysis of variance and factor analysis of mixed data. The results showed the effects of variety, location and their interactions were highly significant for most of the growth, earliness and yield traits. Imported hybrid varieties showed the best performances compared to the local one. Multivariate analysis revealed that 'De cayenne' was earlier, short in size, thin-stemmed, red fruits and less yielding (≈ 1 t.ha-1). The imported hybrids LaaliF1 and KrantiF1 were of strong vegetative vigor, more yielding (> 6 t.ha-1) by developing larger, long and hard fruits. Other hybrids showed intermediate performances. This study highlighted the importance of imported hybrids in improving yield and preservation of chili fruits. However, stability and adaptation analyses to local conditions are necessary for their adoption.
An Empirical Approach for the Variation in Capital Market Price Changes Premier Publishers
The chances of an investor in the stock market depends mainly on some certain decisions in respect to equilibrium prices, which is the condition of a system competing favorably and effectively. This paper considered a stochastic model which was latter transformed to non-linear ordinary differential equation where stock volatility was used as a key parameter. The analytical solution was obtained which determined the equilibrium prices. A theorem was developed and proved to show that the proposed mathematical model follows a normal distribution since it has a symmetric property. Finally, graphical results were presented and the effects of the relevant parameters were discussed.

Chia is an emerging cash crop in Kenya and its production is inhibited by lack of agronomic management information. A field experiment was conducted in February-June and May-August 2021, to determine the influence of nitrogen and spacing on growth and yield of Chia. A randomized complete block design with a split plot arrangement was used with four nitrogen rates as the main plots (0, 40, 80, 120 kg N ha-1) and three spacing (30 cm x 15 cm (s1), 30 cm x 30 cm (s2), 50 cm x 50 cm (s3)). Application of 120 kg N ha-1 significantly increased (p≤0.05) vegetative growth and seed yield of Chia. Stem height, branches, stem diameter and leaves increased by 23-28%, 11-13%, 43-55% and 59-88% respectively. Spacing s3 significantly increased (p≤0.05) vegetative growth. An increase of 27-74%, 36-45% and 73-107% was recorded in number of leaves, stem diameter and dry weight, respectively. Chia yield per plant was significantly higher (p≤0.05) in s3. However, when expressed per unit area, s1 significantly produced higher yields. The study recommends 120 kg N ha-1 or higher nitrogen rates and a closer spacing of 15 cm x 30 cm as the best option for Chia production in Kenya.

Social capital plays an essential role in empowering people for social and economic change even during the pandemic. A livelihood project of the government was implemented among the members of a women’s association of a disadvantaged upland community in Bukidnon province, Southern Philippines for inclusive development. This study was conducted to determine the influence of some socio-economic attributes and the change in the knowledge level on the social capital of the rural women amidst the pandemic. The activities of the project were implemented considering the health protocols imposed by the government during the health crisis. The findings revealed that the trainings conducted resulted to a positive change in the knowledge level among the rural women. This facilitated the production of vegetables for their households and generated additional income very necessary during the pandemic especially that other economic activities were hindered. Similarly, there was a significant increase in the social capital of the rural women during the last two years. The main occupation, sources of income and their ethnicity significantly influenced the social capital of the rural women. The rural development workers and policymakers must consider the social capital of the group in the implementation of poverty alleviation programs.
Impact of Provision of Litigation Supports through Forensic Investigations on...Premier Publishers
This paper presents an argument through the fraud triangle theory that the provision of litigation supports through forensic audits and investigations in relation to corporate fraud cases is adequate for effective prosecution of perpetrators as well as corporate fraud prevention. To support this argument, this study operationalized provision of litigation supports through forensic audit and investigations, data mining for trends and patterns, and fraud data collection and preparation. A sample of 500 respondents was drawn from the population of professional accountants and legal practitioners in Nigeria. Questionnaire was used as the instrument for data collection and this was mailed to the respective respondents. Resulting responses were analyzed using the OLS multiple regression techniques via the SPSS statistical software. The results reveal that the provision of litigation supports through forensic audits and investigations, fraud data mining for trends and patterns and fraud data collection and preparation for court proceedings have a positive and significant impact on corporate fraud prevention in Nigeria. This study therefore recommends that regulators should promote the provision of litigation supports through forensic audits and investigations in relation to corporate fraud cases in publicly listed firms in Nigeria, as this will help provide reports that are acceptable in court proceedings.
Improving the Efficiency of Ratio Estimators by Calibration WeightingsPremier Publishers
It is observed that the performances of most improved ratio estimators depend on some optimality conditions that need to be satisfied to guarantee better estimator. This paper develops a new approach to ratio estimation that produces a more efficient class of ratio estimators that do not depend on any optimality conditions for optimum performance using calibration weightings. The relative performances of the proposed calibration ratio estimators are compared with a corresponding global [Generalized Regression (GREG)] estimator. Results of analysis showed that the proposed calibration ratio estimators are substantially superior to the traditional GREG-estimator with relatively small bias, mean square error, average length of confidence interval and coverage probability. In general, the proposed calibration ratio estimators are more efficient than all existing estimators considered in the study.
Urban Liveability in the Context of Sustainable Development: A Perspective fr...Premier Publishers
Urbanization and quality of urban life are mutually related and however it varies geographically and regionally. With unprecedented growth of urban centres, challenge against urban development is more in terms of how to enhance quality of urban life and liveability. Making sense of and measuring urban liveability of urban places has become a crucial step in the context of sustainable development paradigm. Geographical regions depict variations in nature of urban development and consequently level of urban liveability. The coastal regain of West Bengal faces unusual challenges caused by increasing urbanization, uncontrolled growth, and expansion of economic activities like tourism and changing environmental quality. The present study offers a perspective on urban liveability of urban places located in coastal region comprising of Purba Medinipur and South 24 Parganas districts. The study uses the liveability standards covering four major pillars- institutional, social, economic and physical and their indicators. This leads to develop a City Liveability Index to rank urban places of the region, higher the index values better the urban liveability. The data for the purpose is collected from various secondary sources. Study finds that the eastern coastal region of the country covering state of West Bengal depicts variations in index of liveability determined by physical, economic, social and institutional indicators.

Stevia rebaudiana Bertoni is a plant which has recently been used widely as a sweetener. This medicinal plant has some components such as diterpenoid glycosides called steviol glycosides [SGs]. Rebaudioside A is a diterpenoid steviol glycoside which is 300 times sweeter than table sugar. This study was done to investigate the effect of GA3 (50 mg/L) on the expression of 14 genes involved in Rebaudioside A biosynthesis pathway in Stevia rebaudiana under in vitro conditions. The expression of DXS remarkably decreased by day 3. Also, probably because of the negative feedback of GA3 on MEP-drived isoprenes, GGDS transcript level reached its lowest amount after GA3 treatment. The abundance of DXR, CMS, CMK, MCS, and CDPS transcripts showed a significant increase at various days after this treatment. A significant drop in the expression levels of KS and UGT85C2 is detected during the first day. However, expression changes of HDR and KD were not remarkable. Results revealed that the level of transcript of UGT74G1 and UGT76G1 up regulated significantly 4 and 2 times higher than control, respectively. However, more research needs to shed more light on the mechanism of GA3 on gene expression of MEP pathway.

Information on genetic variability for biochemical characters is a prerequisite for improvement of tea quality. Thirteen introduced tea clones characterized with objective; assessing tea clones based on morphological characters at Melko and Gera research stations. The study was conducted during 2017/18 cropping season on experimental plots in RCBD with three replications. Data recorded on morphological traits like days from pruning to harvest, height to first branch, stem diameter, leaf serration density, leaf length, leaf width, leaf size, petiole length, leaf ratio, internode length, shoot length, number of shoot, canopy diameter, hundred shoot weight, fresh leaf yield per tree. Cluster analysis of morphological trait grouped into four clusters indicated, the existence of divergence among the tested clones. The maximum inter-cluster distance was between clusters I and IV (35.27) while the minimum inter cluster distance was observed between clusters I and II (7.8).Principal components analysis showed that the first five principal components with eigenvalues greater than one accounted 86.45% for 15 morphological traits. Generally, the study indicated presence of variability for several morphological traits. However, high morphological variation between clones is not a guarantee for a high genetic variation; therefore, molecular studies need to be considered as complementary to biochemical studies.
Causes, Consequences and Remedies of Juvenile Delinquency in the Context of S...Premier Publishers
This research work was designed to examine nature of juvenile offences committed by juveniles, causes of juvenile delinquency, consequences of juvenile delinquency and remedies for juvenile delinquency in the context of Sub-Saharan Africa with specific reference to Eritrea. Left unchecked, juvenile delinquents on the streets engage in petty theft, take alcohol or drugs, rape women, rob people at night involve themselves in criminal gangs and threaten the public at night. To shed light on the problem of juvenile delinquency in the Sub-Saharan region data was collected through primary and secondary sources. A sample size of 70 juvenile delinquents was selected from among 112 juvenile delinquents in remand at the Asmara Juvenile Rehabilitation Center in the Eritrean capital. The study was carried out through coded self-administered questionnaires administered to a sample of 70 juvenile delinquents. The survey evidence indicates that the majority of the juvenile respondents come either from families constructed by unmarried couples or separated or divorced parents where largely the father is missing in the home or dead. The findings also indicate that children born out of wedlock, families led by single mothers, lack of fatherly role models, poor parental-child relationships and negative peer group influence as dominant causes of juvenile infractions. The implication is that broken and stressed families are highly likely to be the breeding grounds for juvenile delinquency. The survey evidence indicates that stealing, truancy or absenteeism from school, rowdy or unruly behavior at school, free-riding in public transportation, damaging the book of fellow students and beating other young persons are the most common forms of juvenile offenses. It is therefore, recommended that parents and guardians should exercise proper parental supervision and give adequate care to transmit positive societal values to children. In addition, the government, the police, prosecution and courts, non-government organizations, parents, teachers, religious leaders, education administrators and other stakeholders should develop a child justice system that strives to prevent children from entering deeper into the criminal justice process.

Numerous studies from Sub-Saharan Africa suggest that stigma and discrimination are major problems in the community, with negative attitudes and behavior towards people with mental illness being widespread. In order to assess the whether such negative attitudes persist in the context of Eritrea this study explored the knowledge and perceptions of 90 Eritrean university students at the College of Business and Economics, the University of Asmara regarding the causes and remedies of mental illness A qualitative method involving coded self-administered questionnaires administered to a sample of 90 university students to collecting data at the end of 2019. The survey evidence points that almost 50% of the respondents had contact with a mentally ill person suggesting that the significant number of the respondents experienced a first-hand encounter and knowledge of mental illness in their family and community. The findings show an overall greater science-based understanding of the causes of mental illness to be followed by recommended psychiatric treatments. The survey evidence indicates that the top three leading causes of mental illness in the context of Eritrea according to the respondents are brain disease (76%), bad events in the life of the mentally ill person (66%) and substance abuse or alcohol taking, smoking, taking drugs like hashish. (54%). The majority of the respondents have a very sympathetic and positive outlook towards mentally ill persons suggesting that mentally illness does not simply affect a chosen individual rather it can happen to anybody regardless of economic class, social status, ethnicity race and religion. Medical interventions cited by the majority of the respondents as being effective treatments for mental illness centered on the idea that hospitals and clinics for treatment and even cures for psychiatric disease. Changing perceptions of mental illnesses in Eritrea that paralleled the very caring and sympathetic attitudes of the sample university students would require raising public awareness regarding mental illness through education, using the mass media to raise public awareness, integrating mental health into the primary health care system, decentralizing mental health care services to increase access to treatment and providing affordable service to maintain positive treatment outcomes.
Effect of Phosphorus and Zinc on the Growth, Nodulation and Yield of Soybean ...Premier Publishers
An investigation was carried out at Kogi State University Student Research and Demonstration farm Anyigba during the 2019 wet season to observe the effect of phosphorus and zinc on the growth, nodulation and yield of soybean. The treatments comprised three levels: phosphorus and zinc (0, 30 and 60 kg P2O5/ha; 0, 5 and 10kg Zn/ha) and two varieties TGX 536 – 02D and Samsoy 2. The investigation revealed that application of phosphorus affected growth, nodulation, yield and some yield components of soybean while zinc application, apart from the plant height, which is reduced significantly, had no significant effect on other growth characters, nodulation, yield and yield components. However, it was generally found to decrease most of the characters. Application of 60 kg P2O5/ha gave the highest growth and yield, while 30 kg P2O5/ha gave the highest nodulation. Application of 60 kg P2O5/ha significantly increased yield to 1.9t/ha, which was significantly higher over the control plots, which gave 1.7t/ha. Crude protein and oil contents of the seeds were not significantly affected by phosphorus application but were significantly affected by zinc application, which significantly decreased protein content as its amount an increase from 0 to 10 kg/ha, and significantly increased oil content from 0 to 5kg/ha and decreased it below 5kg/ha. It was also revealed that the two varieties responded similarly to phosphorus and zinc in terms of growth, grain yield and crude protein content of the seeds.
Influence of Harvest Stage on Yield and Yield Components of Orange Fleshed Sw...Premier Publishers
A field experiment was conducted at Adami Tullu Agricultural Research Center in 2018 under rainfed condition with supplementary irrigation to determine the influence of harvest stage on vine yield and tuberous root yield of orange fleshed sweet potato varieties. The experiment consisted of four harvest stages (105, 120, 135 and 150 days after planting) and Kulfo, Tulla and Guntute varieties. A 4 X 3 factorial experiment arranged in randomized complete block design with three replications was used. Interaction of harvest stage and variety significantly influenced above ground fresh biomass, vine length, marketable tuberous root weight per hectare, commercial harvest index and harvest index. The highest mean values of above ground fresh biomass (66.12 t/ha) and marketable tuberous root weight (56.39 t/ha) were produced by Guntute variety harvested at 135 days after planting. Based on the results, it can be recommended that, farmers of the study area can grow Guntute variety by harvesting at 135 days after planting to obtain optimum vine and tuberous root yields.
Performance evaluation of upland rice (Oryza sativa L.) and variability study...Premier Publishers
This study aimed at assessing genetic variability and to evaluate the performance of 13 improved upland rice varieties for yield and its components based on morphological traits. The field experiment was conducted using a randomized block design at Guraferda and Gimbo districts in the 2019 main cropping season. The analysis of variance (ANOVA) over the two locations revealed significant differences (p≤ 0.05) among varieties for days to 50% heading, days to 85% maturity, panicle length, thousand-grain weight, and grain yield. Similarly, the ANOVA for variety by location interactions depicted significant differences among the tested varieties for days to 50% heading, days to 85% maturity, and thousand-grain weight. High heritability was obtained from days to heading (88.5%), panicle length (85.0%), and grain yield (85.2%), which indicates these traits can be easily improved through selection. High to medium broad sense heritability and genetic advance as percentage of the mean for days to heading, thousand-grain weight, and grain yield indicates a good opportunity for improvement through selection using their phenotypic performance. This is mainly due to the high role of additive gene action in the expression of such traits. This study confirmed the presence of variability among varieties for most of the studied traits, which will create an opportunity for breeders to improve rice yield and other attributes.
Response of Hot Pepper (Capsicum Annuum L.) to Deficit Irrigation in Bennatse...Premier Publishers
This study was conducted at Enchete kebele in Benna-Tsemay Woreda, South Omo Zone to evaluate the response of hot pepper to deficit irrigation on yield and water productivity under furrow irrigation system. The experiment comprised four treatments (100 % of ETc, 85% of ETc, 70 % of ETc and 50% of ETc), respectively. The experiment was laid out in RCBD and replicated four times. The two years combined yield results indicated that, the maximum total yield (20.38 t/ha) was obtained from 100% ETc while minimum yield (12.92 t/ha) was obtained from 50% of ETc deficit irrigation level. The highest WUE 5.22 kg/ha mm-1 was obtained from 50% of ETc. Treatment of 100% ETc irrigation application had highest benefit cost ratio (4.5) than all others treatments. Applying 50% of ETc reduce the yield by 37% when compared to 100 % ETc. Accordingly, to achieve maximum hot pepper yield in areas where water is not scarce, applying 100% ETc irrigation water application level throughout whole growing season under furrow irrigation system is recommended. But, in the study area water scarcity is the major limiting factor for crop production. So, it is possible to get better yield and water productivity of hot pepper when we apply 85% ETc irrigation water throughout growing season under furrow irrigation system.
Harnessing the Power of Agricultural Waste: A Study of Sabo Market, Ikorodu, ...Premier Publishers
Nigeria is still burdened with huge responsibilities of waste disposal because the potential for benefits of proper waste management is yet to be harnessed. The paper evaluates the capacity of the Sabo Cattle market in producing the required quantities of waste from animal dung alongside decomposed fruits with a view to generating renewable energy possibilities for lighting, security and other business activities of the market. It is estimated that about 998 million tons of agricultural waste is produced yearly in the country with organic wastes amounting to 80 percent of the total solid wastes. This can be categorized into biodegradable and non-biodegradable wastes. The paper evaluates the capacity of the Sabo Cattle market in producing the required quantities of waste from animal dung alongside decomposed fruits with a view to generating renewable energy possibilities for lighting, security and other business activities of the market. The Sabo market was treated as a study case with the adoption of in-depth examinations of the facility, animals and products for sale and waste generated. A combination of experimental, interviews (qualitative) and design simulation (for final phase) was adopted to extract, verify and analyse the data generated from the study. Animal waste samples were subjected to compositional and fibre analysis with results showing that the sample has high potency for biogas production. Biodegradable Wastes are human and animal excreta, agricultural and all degradable wastes. Availability of high quantity of waste generated being organic in Sabo market allows the use of anaerobic digestion to be proposed as a waste to energy technology due to its feasibility for conversion of moist biodegradable wastes into biogas. The study found that at peak supply period during the Islamic festivities, a conservative 300tonnes of animal waste is generated during the week which translates to over 800kilowatts of electricity.
Influence of Conferences and Job Rotation on Job Productivity of Library Staf...Premier Publishers
The general purpose of this study is to investigate the influence of conferences and job rotation on job productivity of library staff in tertiary institutions in Imo State, Nigeria. The survey research design was used for this study using questionnaire as an instrument for data collection. This study covered the entire population of 661. Out of these, 501 copies of the questionnaire representing 75.8% were duly completed and returned for analysis. Student’s t-test was used to analyze the research questions. The finding showed that conferences had no significant influence on the job productivity of library staff in tertiary institutions in Imo State, Nigeria (F cal= 7.86; t-vale =6.177; p >0.005). Finding also showed that job rotation significantly influences job productivity of library staff in tertiary institutions in Imo State, Nigeria (F-cal value= 18.65; t-value = 16.225; P<0.05). This study recommended that, government should ensure that library staff participate in conferences with themes and topics that are relevant to the job they perform and also ensure that there should be proper evaluation and feedback mechanism which aimed to ensuring control and minimize abuse of their development opportunities. Again, there should be written statement of objectives in order to sustain job rotation programmes. Also, that training and development needs of library staff must be identified and analyzed before embarking on job rotation processes as this would help to build skills, competences, specialization and high job productivity.

Microscopic examination of urine samples collected from geriatric dogs revealed increased numbers of erythrocytes, leucocytes, epithelial cells and pus cells along with casts, bacteria, spermatozoa and crystals of various shapes. Among the different crystals, triple phosphate or struvite were predominant, followed by calcium oxalate dihydrate, calcium oxalate monohydrate and ammonium urate or biurate. The struvite crystals were, coffin-lid shape and while calcium oxalate dihydrate were octahedron or envelope and monohydrate crystals demonstrated “picket fence” and “dumbbell” and “hemp seed” appearance. Brown or yellow-brown spherical bodies with irregular borders with thorn-apple appearance were shown by ammonium urate or biurate crystals. SEM aspects of magnesium ammonium phosphate crystals revealed perpendicular columnar strata, few with scattered hexa or octa-hedral coffin-lid shaped crystals and calcium phosphate crystals were like cracked eggshells. Presence of wavy phases with sundry areas (uric acid), picket fence (calcium oxalate monohydrate) and typical envelope (calcium oxalate dehydrate) were electron microscopic appearance of various crystals.
Gentrification and its Effects on Minority Communities – A Comparative Case S...Premier Publishers
This paper does a comparative analysis of four global cities and their minority districts which have been experiencing the same structural pressure of gentrification. The main contribution of this paper is providing a detailed comparison of four micro geographies worldwide and the impacts of gentrification on them: Barrio Logan in San Diego, Bo-Kaap in Cape Town, the Mission District in San Francisco, and the Rudolfsheim-Fünfhaus District in Vienna. All four cities have been experiencing the displacement of minority communities due to increases in property values. These cities were chosen because their governments enacted different policies to temper the gentrification process. It was found that cities which implemented social housing and cultural inclusionary policies were more successful in maintaining the cultural and demographic make-up of the districts.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

MATERIALS AND METHODS
A total of twelve matured grass cutters
(Thryonomysswinderianus), 6 males and 6 females
were purchased from Otukpo, Benue state, Nigeria.
They were transported and housed in customized
laboratory rat cages of the Department of Anatomy
Laboratory, Faculty of Veterinary Medicine, Ahmadu
Bello University, Zaria, Nigeria. They were fed grasses,
sweet potato, groundnut pellets, sugar cane and given
water ad libitum prior to commencement of the study.
The rats were weighed using a balance (SALTER
model 250) with a sensitivity of 0.1g and euthanized
using gaseous chloroform in a confined container.
Three different methods were used to clean the bones,
namely: water maceration, burial and chemical (Sodium
hydroxide). Four rats (2 males, 2 females) were used
for each of the three methods.
Maceration
The rats were dissected using a surgical blade to
remove skin, thoracic, abdominal and pelvic contents.
The muscles were carefully dissected and teased away
to leave the bones with minimal soft tissue
attachments.
They were then put into different plastic buckets
(labelled according to the rat’s weights) containing
water enough to submerge the bones. The plastic
buckets were then covered air tight and placed under
the sun for days with change of water every other day
after which the water was drained and the bones
recovered and dried. The number of days it took for
complete maceration was noted and recorded.
Burial
With this method the rats were dissected using a
surgical blade to remove skin, thoracic, abdominal and
pelvic contents. The muscles were carefully dissected
and teased away to leave the bones with minimal soft
tissue attachments. The partially cleaned bones were
then wrapped with mesh sacs, buried two feet deep in
rich humid soil and checked every other day to
determine when the bones can be recovered. The
recovered bones were washed with water to remove
attached soil and then air dried under room
temperature. The number of days it took for complete
bone recovery was noted and recorded.
Chemical (Sodium hydroxide)
The rats were carefully dissected using a surgical blade
to remove as much soft tissue and internal contents as
possible from the bones. The partially cleaned bones
were immersed in plastic buckets containing 3%
solution of NaOH. The plastic buckets were then placed
under the sun and checked every 30 minutes to recover
the bones as they were cleaned in order to avoid
digestion of the bones by the NaOH. The recovered
bones were then washed in running water and air dried
under an electric fan. The time it took for complete
recovery were also noted and recorded.
Presentation of bones
Photographs of the bones recovered from the three
methods were taken as a whole noting the colour
change. The bones were then articulated using glue,
noting the number of bones that constituted each
segment.
2.5 Statistical analysis
Graph pad prism version 5.0 was used to calculate the
range, mean, standard error of mean of the length of
bones and correlation between weight of the rats and
length of its bones. P - Values less than 0.05 were
considered significant.
RESULTS
Cold water maceration took 8 days for complete bone
recovery, turned the bones white, emitted strong odour
and was cheap to prepare. Burial method took 14 days,
turned the bones brown, emitted very strong odour and
was also cheap to prepare. The chemical method took
8 hours for complete bone recovery, turned the bones
ash and was expensive. The chemical method is the
best method for the bone preparation of this rat. Table

revealed different effects on the bones such as colour
change, odour, length of time taken for complete bone
recovery and relative damage. However, all methods
showed the ability to separate the extremities of long
bones from the shaft during preparation, although this
property was seen to reduce in the weightier animals.
Maceration method (at 31˚c) in the rainy season took 8
days for complete bone recovery which turned the
bones whitish and produced a strong odour from the
bones. There were no cracks after these number of
days.
Burial method which was also done in the rainy season
took 14 days for complete bone recovery. It turned the
bone brownish and produced a strong nauseating
odour from the bones. No cracks were seen after these
number of days.
Chemical method using Sodium hydroxide (3%) at 31˚c
in the rainy season took approximately 8 hours for
complete bone recovery. It turned the bones ash as
though it had been cooked with the extremities of long
bones appearing darker then the shaft. The bones were
odourless. However, cracks in smaller bones were
noticed in smaller animals.
The Scapula presented a roughly triangular shaped
structure with a convex vertebral border and a slightly
convex cranial border making the cranial angle
indistinct. The caudal border is concave with a
pronounced caudal angle. The scapula spine divides
the lateral surface almost equally and extends
downward (attached by a cartilage) to form a prominent
triangular shaped suprahamatus and hamatus
processes (1 and 2).

presents a distinct deltoid tuberosity protruding from the
middle of the shaft. The distal extremity presents the
olecranon fossa, lateral and medial epicondyle, lateral
and medial condyle cranially, trochlea and
supratrochlea fossa caudally (Fig. 3 and 4).
The Ulna is the longer of the forearm bones and
attaches to the Radius proximally and distally leaving
an expansive interosseus space. Each bone ends up
distally with a styloid process (Fig. 5 and 6).

DISCUSSION AND CONCLUSION
The results obtained from the three methods of bone
preparation employed in this study showed that all
three methods possess advantages and disadvantages
which determines the best suitable for use in small
animals.
Sodium hydroxide produces no odour and recovers the
bones quickly than other methods. This makes it
suitable for faster skeleton extraction when needed
urgently. However, it is relatively expensive when
compared to the other methods and it dissolves smaller
bones into bone halls. The flesh of the animal is not
dissolved at the same time by the chemical therefore
7. Grasscutter’s Forelimb
Int. J. Vet. Sci. Anim. Husb. 011
bones need to be removed from the chemical as soon
as the flesh dissolves. Some bones with much flesh like
the skull and vertebral column need more exposure
time which leads to cracks and softening of bones.
Also, the appearance of the bones after recovery is not
aesthetic as the extremities of long bones appear
darker although whitening can be achieved by use of a
bleaching agent.
Maceration takes longer time, produces strong and
distasteful odour but is suitable in terms of less bone
damaging effect, whitening of the bones and
affordability.
Burial method takes the longest time in this animal,
produces very strong nauseating odour and turns the
bones brownish. However, its suitability is based on the
fact that it is not expensive and does not damage
bones except when left longer in the soil for more than
two weeks.
The mean weight of the male grasscutter
(5167±0.2023kg) is greater than that of the female
(0.8167±0.1276kg) which agrees with the findings of
Merwe (2000). The statistical significance (P > 0.05)
and positive r values obtained signifies that the weights
of grasscutter positively affect the length and size of its
bones, that is the weightier the animals, the longer its
length of bones.
The hamatus and suprahamatus processes seen on
the scapula of the grasscutter have also been reported
in other rodent species (Rudolf and Stromberg, 1976;
Ozkan et al., 1997) and carnivorous animals (Sisson
and Grossman, 1975). The presence of the distinct
deltoid tuberosity on the shaft of the humerus agrees
with reports on other rodents but differ in morphology.
The supracondylar foramen seen on the distal extremity
of the humerus is similar to what is reported for cats
(Dyce et al.,2002).
The Ulna and radius presented no significant
differences from the typical mammalian bones except
for its extensive interosseus space. The number and
arrangement of the manus is typical of the rodentia
order and agreed with the work of Green (1968) on the
albino rat. The arrangement of the carpal bones into
two rows agrees with what is obtainable in other
mammals such as horse, pig, dog, cat and ruminants
(Sisson and Grossman, 1975). The observation of five
digits in this rat is consistent with what is reported in
other rodent species such as the african giant rat
(Oludeet al., 2010, Salami et al., 2011) and albino rat
(Green, 1968). The arched and pointed shape of the
distal phalanges is for easy burrowing and shovelling
(Fitzinger, 1997).
