The freshwater shrimp Atya scabra Leach, 1815 is traditionally captured in the Bia river, in the area of the South-Comoé, precisely in Biaka and Aboisso. The aim of this study was to investigate if sexual differences could affect external morphology in freshwater shrimp Atya scabra, to determine sexual dimorphism related to morphological differences during the maturation in this species. Thus, morphometric measurements in 360 specimens of A. Scabra were examined at each study site for sexual dimorphism from August 2014 to July 2015. In Aboisso, mean values recorded at lpp, Lantn and Lantl were 8.5 ± 7.8; 78.5 ± 84.1 and 47.5 ± 47.4 mm in males. The average values obtained were respectively 6.5 ± 4.9; 58.5 ± 46 and 25 ± 24 mm for lpp, Lantn and Lantl in females. In Biaka, Mean values in males were 7.5 ± 7.8; 71.5 ± 55.9 and 37.5 ± 31.8 mm. In females, mean values recorded were 6 ± 5.7; 60 ± 50.9 and 27.5 ± 21.9 mm. Concerning the sexual dimorphism index, the χ2 test showed that there is no significant difference (P > 0.05) between the SDI determined at the level of the width of cephalothorax and the 3rd pair of pereiopod (lpp) in the specimens of Atya scabra of Aboisso and those of Biaka. Analysis of the data shows two modal of distribution in males, females and in both sexes combined. When considering the sexes combined, the young recruits have an average size (Lt) of 83 ± 3.8 mm while the latter was 107.6 ± 12.1 mm in the oldest freshwater shrimps of the species A. scabra captured in Aboisso. But in Biaka, the young individuals had an average size (Lt) of 81.4 ± 4.3 mm. As for the oldest individuals, the value of the estimated average size is 107.0 ± 11.2 mm in the sexes combined. The present study was made in order to have data on the size frequency distribution and the sexual dimorphism index of this species.

Dayak indigenous communities have traditionally maintained and normalized the value of their ancestors, as a form of efforts to maintain these values, Dayak indigenous communities continue to perform rituals Balian in their interactive activities with nature. The research approach used is qualitative research with case study methods and research informants as a data source while data analysis techniques use stages of data collection, data reduction, data presentation and verification of conclusions conducted continuously until saturated. The results showed that the value of Dayak indigenous communities in the hall Kiyu hereditary upholds their pattern of life and relationship with nature. The value of life includes rice farming where rice is sacred and must be treated according to its dignity from planting to put back into the barn. According to belief, rice is a celestial plant and has decreased its dignity because it is in the dark world (real world, earth) must be restored to its sacred form of presenting various ceremonies for him who is sustainable.

Production and Profitability Study of White Jute Seed at Farmer’s Level in Different Areas of Bangladesh
The objective of this study was to investigate the cost and return structures of white jute seed cultivation in Bangladesh. This study was conducted in two locations in three consecutive years 2013-15). The sample included 120 farmers selected using a purposive sampling method, consisting of 60 from each district. Sample size was same for three years. Survey questionnaires were used as the main instrument for data collection. Descriptive statistics and cost and return analysis were used for data analysis. The results indicate that the cost of production (99175 tkha-1) and output (123502 tkha-1) was higher in Tangail than Manikganj. Lowest cost of production (80252 tkha-1) was recorded in 2013 in Manikganj and maximum (102470 tkha-1) in 2014 in Tangail. Average BCR of white jute seed production of two locations was 1.25. Cost of production varies year to year and place to place due to variation in land rent value, labour wages, land preparation cost etc. This result indicates that profitability of jute seed production is almost same in two zones and by product yield is also important in case of white jute seed production.

This research work seeks to explore the capitals utilization for livelihoods among households with People Living with HIV/AIDS (PLWHA) in Kaduna State, North West, Nigeria. The study adopts a qualitative procedural and explicitly phenomenological in nature and employed in-depth interviews, participatory and non-participatory observations as research tool. The interview period of conducting the fieldwork was from August to November, 2019 and twenty-one households with PLWHA in Kaduna State, North West, Nigeria were utilized as the qualified target. This research results discovered that households with PLWHA utilized a range of capitals for their livelihoods and created their livelihoods patterns based on their available capitals. The findings revealed that there are five types of capitals as resources utilized by households with PLWHA to fashioning out their livelihoods patterns and such capitals are social capital for resolving households difficulties and participating in the villages activities; financial capital utilized by households for investments and land accretions; human capital like knowledge and know-how useful in their line of businesses to maintain their households; natural and physical capitals that are utilized as means to make every effort to make living like cutting trees for cooking and selling, collecting of herbs from the forest for medication, road network among other things. Based on the findings of this study, it is recommended that authorities need to train households with PLWHA on how to enhance their capacities on livelihoods capitals utilization effectively. The government should come up with policies that can take care and support the livelihood hood activities of households with PLWHA.

Pediculus humanus has always been the most obstinate ectoparasites that evolved with human beings and persist till today throughout the world. These wingless nemeses are extremely hard to deal with, because they prefer the human body temperature for their existence and propagation or reproduction. Numerous studies have been conducted to exterminate these blood feeders by the employment of several natural as well as synthetic regimens but not with an ideal proficiency. Anyhow, a multifaceted product would be beneficial for killing and removing the lice and their stubborn nits from the human hair shafts permanently. Our current focus is to introduce an all rounder treatment with a marvellous fusion of deltamethrin (DMT) and diisopropylfluorophosphate (DFP) along with dimeticone (PDMS). The tonic lotion with the amalgamation of aforementioned antilice candidates will stop lice reproduction, accessory gland secretions that are mediated by corpora allata, nit formation, neurotransmission and behavioural responses which will ultimately lead to clearance of these hematophagous insects. So as there is no promising solution to this global discomfort at present, our novel proposal will hopefully pave a new way to eradicate lice forever.

Wheat as an important staple food crop that is facing serious threat by increasing the phenomenon of salinity in the vast area worldwide. Due to climate change, more arable lands are going to be depended on irrigation which causes raising of salinity in the soil where then affect negatively on seed germination and growth of plants. Araz, is one of the used wheat cultivar in Iraq and Kurdistan where it was tested for its salt tolerance level by using salt solutions 0.01, 0.02 and 0.05 mol L-1, which answer to 0.58, 1,17 and 2,92g -1, and comparing these solutions as TDS (Total Dissolved Solids) to Electrical Conductivity (Soil Extract) EC(dS/m) for salt tolerance classification. The results showed significant effects of salt level 0,01 molL-1 on germination parameters except for seed water uptake. By increasing salt levels to 0.02mol and 0.05molL-1 the effects are negatively increased. What is concerning the effect of salt levels on growth parameters, the obtained results indicated that generally and without exception negatively effects of salt levels on growth parameters but. There were no difference effects between salt levels 0.01mol/L and 0.02molL-1on fresh weight of radicle, while increasing salt levels to 0.02 molL-1 up to0.05 molL-1the effects on growth were more severe. Salt level 0.05 molL-1 which is equivalent to TDS range 2,000-5,000 mgL-1 and it is answer to 3,0 -7,5 EC (dS/m , seen as not tolerance for cultivation wheat cultivar Araz.

Wheat is the most widely grown crop in the world and provides 20% of the daily protein and calories for 4.5 billion people. It is the second most important food crop in the developing world after rice. Charmo, Maroof and Alla are a new promising rust-resistant wheat varieties were have been tested for their salinity tolerance through seed water uptake, (germination percentage and germination mean), as well as growth of radical and plumule. The varsities was tested for their salt tolerance level by using salt solutions concentration levels with a control, 0.01, ,0.03.0,05, 0.07, and 0.09 molL -1, which are answer to 0.0, 0.58,1.75,9.2 ,4.01 and 5.26 gL -1,that symbolized as C0,C1,C2,C3,C4and C5. The results showed significant effects of varsities on water uptake, germination percentage germination mean time, wet and dry radical, but not significant effect on radical number and length as well as plumule length and wet dry plumule. What is concerning the effects of salt levels on germination parameters and growth of varieties, we noted significant effect of salt on germination mean, germination percentage, radical and plumule length as well as on wet radical weight. And the interaction between varsities and salt levels, the result has shown significant effect of interaction between varsities and salt levels on dry radical. Salt levels from C3 have indicted to have significant effect on germination on wet radical but not significant effect on water uptake, dry radical, as well as on wet and dry plumule. The results of the effect of varieties on germination and growth parameters showed that charmo and maroof are better than Alla. The study showed that Charmo and Maroof are toleration C2 respect but Alla dose not that is why it cannot be recommended to be used in soil with EC 0.80–2.50 which answers to C2 that is equivalent to 456–1425 mgL-1 but Charmo and Maroof have more tolerance at this level respectively.
