This document summarizes research on air spora (fungal spores and other biological components in air) over onion fields in Udgir, India from 1999-2001. The researchers found that Deuteromycetes dominated the airspora, contributing 71.76% of total spores, followed by Ascomycetes at 16.36%. The most common spore types were Cladosporium at 21.68% and Alternaria at 16.92%. Meteorological factors like temperature, humidity and rainfall affected spore release and composition. The study of air spora can help predict plant disease outbreaks and advise farmers on prevention and treatment.

Currency notes are handled by a large number of people under a variety of personal and environmental conditions. A total of ninety six samples of one hundred naira denomination of Nigerian notes were procured from seven Local Government Areas (LGA) of Ebonyi State, Nigeria. The aim of the study was to determine the palynotaxa and parasitic load prevalent on currency notes. The leachates of currency notes were obtained and subjected to acetolysis and examined microscopically. Twenty six fungal spores type were recorded and were highly dominated by spores of Libertelli spp., Botrytis spp. and Spadicoides spp. Pollen achieved 54 % of the total bio-particles, whereas fungal spores and parasitic worms achieved 35.2 % and 10.60 %, respectively. The presence and relative abundance of these palynotaxa and parasites in currency notes affirms their propensity to spread vectors of diseases.
Fungal contamination of markets in Warri Metropolis: A threat to food securit...Innspub Net
There is always population surge towards physical market because it is a major outlet for purchase of food items and other human needs. Biological contamination of air is one of the serious issues of the environment varying among geographic areas and sampling heights. The aeromycology of three major markets in Warri metropolis which include Effurun market, Igbudu market and Main market using open plate method was evaluated. The study was conducted for the period of six (6) months (April to September, 2017) at two heights: human height (1.5m) and building height (3.5m) and three different locations (foodstuffs, clothing and abattoir sections) in each of these markets. Petri dishes containing PDA medium were exposed for 5 mins and incubated in the laboratory for 2–3 days. Developed fungal colonies were counted and sub-cultured to fresh PDA medium for identification by morphological and microscopic examination using standard identification keys. A total of 6145 colonies with 35 species were isolated and identified. Main fungi identified with their percentage frequency of occurrence include Aspergillus niger 699(11.37%), Mucor mucedo 459(7.47%), Penicillium candidum 404(6.57%), P. digitatum 395(6.43%), Monilia sp 324(5.27%) among others. Off these fungi, members of the Deuteromycotina contributed 46.58%, Ascomycotina 38.76% and Zygomycotina 14.66%. The population of fungal colonies varied from month to month as follows: July>August>June>September>May>April. Human height has 4285(60.73%) colonies while building height was 1860(30.27) colonies. Igbudu market, Main market and Effurun market have 2412, 2030 and 1702 fungal colonies respectively. There are strong indications that these market environments are heavily contaminated with airborne fungal spores which may pose a serious threat to food security and human health. Continuous clean-up exercise of these markets is imperative.
The present investigation deals with the fungal disease of fresh water fishes in Godavari river of Nanded district from September-2013 to February-2014. Total 968 fish specimens where about 168 fishes under 9 fish species (5 cultrable and 4 non culturable) were infected fungal disease. Among cultrable species most fungal infected fishes was C.mrigala (23.81%) , L. rohita (17.02%) and C.idellus(12%) Among non culturable species the most fungal infected C.punctatus (28.57%)
C.striatus (15%) P.ticto(13.33%) Infection in culturable fish species was less (16.14%) than non culturable species (17.35%) Three genera of fungi were identified were branchiomyces sp. was associated with gill rot disease and saprolengia sp. and aphanomyces sp. were associated with ulcer types of disease. The incidence (%) disease was highest in the month January (36.76%) fallowed by December (34.58%) and November (27.59%).
Three new records of copepods (Siphonostomatoida) parasitic on marine fishes ...DrNajimRKhamees
Three parasitic copepods (Siphonostomatoida) belonging to three different genera were recovered from marine fishes of Iraq, and are listed here as new records. The sea lice Caligus epinepheli Yamaguti, 1936 (Caligidae) was collected from the Japanese threadfin bream, Nemipterus japonicus (Bloch). It had been frequently reported from teleost fishes around the world. The second record, comprising male and female, was another caligid, rarely caught from fishes – Hermilius longicornis Bassett Smith, 1898, collected from the giant catfish, Netuma thalassina (Rüppell). This paper features the first description of the male
of the latter species. The third record was the lernanthropid, Lernanthropinus temminckii (von Nordmann, 1864) (Lernanthropidae), redescribed based on the specimens collected from the greater lizard fish, Saurida tumbil (Bloch) (Synodontidae). In order to clarify its taxonomic status, our specimen was compared with the holotype of L. gibbosus (Pillai, 1964) from the collections of Zoological Survey of India, Kolkata, and the syntypes of L. sauridae Do in Ho and Do, 1985 and L. temminckii from the collections of the Smithsonian Institution, Washington D.C. We found similarities in the morphology of the body, mouthparts, and legs 1–4 in three above-mentioned species. The prominent feature, the setation pattern of legs 1 and 2 was similar in all the female specimens examined. In the light of this, we formally relegate L. gibbosus and L. sauridae to synonymy with L. temminckii. Another important similarity is that Lernanthropinus gibbosus, L. sauridae, and L. temminckii have exclusively been parasitic on lizardfishes (Synodontidae). The attachment site of all three copepods reported form Iraq were the gill filaments.

Insecticidal activities of diketopiperazines of Nomuraea rileyi entomopathoge...IJEAB
Entomopathogenic fungi are fungal organisms extensively used in various parts of the world as biopesticides against insect pests that cause important economic damage. Various secondary metabolites produced by these fungi have many potential biological activities. The present study was undertaken to evaluate the insecticidal activity of extracts and pure compounds from Nomuraea rileyi (Farlow) Samson entomopathogenic fungi against Spodoptera frugiperda Smith (Lepidoptera), Ceratitis capitata Wiedemann (Diptera) and Tribolium castaneum Herbst (Coleoptera), three insect pests that generate serious economic losses in the northwest of Argentina. Diketopiperazines were extracted from the culture free supernatant of the media with ethyl acetate. Antifeedant properties were detected in all extracts under dietary choice conditions (300 ug/ g of diet). The maximum antifeedant activity was noted in cycles (Pro-Val) (86.02) and cycle (Pro-Phe) (73.47), while the rest of the extracts and metabolites exhibited varying degrees of moderate or less toxic effects. The maximum oviposition deterrence against C. capitata (55.86%) was recorded with cycle (Pro-Phe) at a 50 µm/cm2 dose. Culture medium extracts supplemented with insect remains and all pure compounds showed repellent action against T. castaneum. The main repellency was observed in phenylacetic acid and cycle (Pro-Val) with RI values of 42 and 41% respectively. The present study would suggest the possible utilization of entomopathogenic fungal metabolites as an effective agent for controlling insect pests that cause important economic losses.
Abstract— Airborne pollen calendars are useful to estimate the flowering season of the different plants as well as to indicate the allergenic potential present in the atmosphere at a given time. In this study, a 1-year survey (from January 2013 to February 2014) is presented of the atmospheric concentration of pollen types in Guarda (Portugal), using a 7-day Hirst volumetric trap. The daily mean concentration of both the number of pollen grains and the main pollen season was determined as well as the bi-hourly variations. The highest airborne pollen concentration was found during early spring and early summer. Contrastingly, December was the month with the lowest pollen concentration. The major pollens sampled were Quercus, Pinaceae, Poaceae, Cupressaceae, Urticaceae, Apiaceae, Oleaceae and Polygonaceae. Some differences were found in the intradiurnal distribution patterns of the pollen types studied, with some taxa types being predominantly sampled in the morning (8:00-10:00 a.m.) while others were more evident in the late evening hours (8-10 p.m.). Finally, these results were compared with the forecast made by the Portuguese Aerobiology Network for the central region of Portugal, revealing some significant differences in the pollination periods.
Effect of Climate Change on Copepods Diversity in a Subtropical Pond of JammuAnuragSingh1049
The prevalence of copepods that constitute an important role in food chain of aquatic ecosystem and act as indicators of productivity were examined in Kunjwani pond, Jammu. Five copepod species, Cyclops vicinus, Mesocyclops hyalinus, M. leukarti, Paracyclops fimbriatus and Neodiaptomus diaphorus were recorded along with their different level of developmental stages like nauplius, metanauplius and copepodite. These exhibited trimodal peaks during March, June and October. The data revealed that their distribution is correlated with physico-chemical factors. January to June higher density may be influenced by temperature (19.89-34.5 0C), suspended matter (50.0-112.5 mg/l.), pH (7.58-9.98), DO (2.68-11.0 mg/l.), Ca++ (12.49-31.30 mg/l.) and Mg++ (2.64-8.68 mg/l.). The species diversity index ranged between 0.9583-1.6539.

Investigations were carried out to see the effect of pesticide 'companion' on the proximal composition and enzyme namely amylase, GOT and GPT of whole green gram in the early stages of germination. The findings revealed that the pesticides increase the enzyme activity in the early stages of germination and thus increase the metabolic rate. The Vitamin-C content was also enhanced with the use of pesticide, but there was a decrease in the proximal composition of the gram when treated with pesticide.

Results of isolation and identification showed the presence of fourteen fungi associated with water Hyacinth leaves including; Alternaria sp., Aspergillus flavus, Aspergillus niger, Drechslera sp., Chaetomium sp., Cladosporium sp., Fusarium solani, Macrophomina phaseolin, Mucor sp., Mycelia Sterile Fungi, Pythium aphanidermatum, Ulocladium sp., Rhizopus sp. and Trichoderma sp. at different percentages . However, the percentages of presence were deferent and the most frequently were A. alternata and Rhizopus sp. reached 76.33% and 80.40 % respectively. The percentages of the other fungi were ranged between 4.25% -30.60 %. It has been found that nine of these fungi, the more prevalent, showed high capacity of inducing infection on Water hyacinth leaves at percentages ranged between44.4% – 100% compared with zero infection in control. Macrophomina phaseolina, Pythium aphanidermatum and Rhizopus sp. were found to be the more pathogenic with disease severity attained to 100 %. Different symptoms were developed on the leaves inoculated with different fungi as spotting and wilting followed by leaves dryness. This is the first report for fungi associated with water hyacinth leaves at Al-Kraat area in Iraq.

Investigations were carried out to see the effect of pesticide 'companion' on the proximal composition and enzyme namely amylase, GOT and GPT of whole green gram in the early stages of germination. The findings revealed that the pesticides increase the enzyme activity in the early stages of germination and thus increase the metabolic rate. The Vitamin-C content was also enhanced with the use of pesticide, but there was a decrease in the proximal composition of the gram when treated with pesticide.
Afghanistan as a landlocked country occupies crucial geo-strategic
location connecting East & west Asia. This work is also the sincere effort to highlight the
factors which can bring sustainable development and peace in Afghanistan & also those
negative factors which are encouraging extremism of Taliban, terrorism and undue interference
by some countries. Generally it has been seen that the regional powers are also vary in action.
I also highlight the role of regional and trans- regional actors which are creating obstacles
in the construction of peaceful Afghanistan. I have also try to highlights the suggestions and
recommendation for the establishment of sustainable development & peace in afghanistan
through the collective support of major powers.

The research paper focuses on the Indian immigrant's experiences of immigration, nostalgia, language,
tradition, and acculturation in the host land with reference to Uma Parameswaran's literary fiction, "What Was
Always Hers". As a diasporic writer, she has seen and experienced immigrant life in the host country, Canada
and in her diasporic works; she has highlighted Indian immigrants' cultural displacement in the adopted country,
Canada. In the present book, she has explored the immigrant life of Indians especially immigrated women in their
adopted country. Her characters are always live in confusion to accept the culture of the native country or host
country and express their socio-cultural ties towards their homeland.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
