Diapause development is a complex process involving several eco-physiological phases. Understanding these phases, especially diapause termination, is vital for interpreting the life history of many insect species and for developing suitable predictive models of population dynamics. The pine processionary moth is a major defoliator of pine and a vertebrate health hazard in the Mediterranean region. This species can display either univoltine or semivoltine development, with a pupal diapause extending from a few months to several years, respectively. Although the ecological and applied importance of diapause is acknowledged, its physiological regulation in either case remains obscure. In the present study, we characterize pre-termination, termination and post-termination phases of pupae developing as univoltine or remaining in prolonged diapause. Changes in metabolic activity are monitored continuously using thermocouples, comprising a novel method based on direct calorimetry, and periodically by use of O-2 respirometry. The two methods clearly detect diapause termination in both types of pupae before any visible morphological or behavioural changes can be observed. Univoltine individuals are characterized by an increase in metabolic activity from pre-termination through to termination and post-termination, ultimately resulting in emergence. Remarkably, a synchronous termination is observed in individuals that enter prolonged diapause instead of emerging; however, in these pupae, the increased metabolic activity is only transient. The present study represents a starting point toward understanding the eco-physiology of diapause development processes in the pupae of the pine processionary moth.

The present study was conducted to assess the livelihood status of fish fry and fingerling traders and socioeconomic condition in the greater Jessore, Bangladesh from April 2013 to September 2013. Data were collected through the use of well-structured questionnaire from the selected area. 73% of traders have single family but only 27% have joint family. 45% fish fry and fingerling traders family has four members. 20% family has five members, 14% family has six members, 12% family has three members 9%family has seven to eight members respectively. 92% traders has own bank account but only 7% traders uses their bank account when they trade fry and fingerling. 87% traders have secondary business like rickshaw business, fruit business, cloth business, fish trading etc. Among 300 fish fry and fingerling traders the sanitation facilities are present 100%. It was found that 69% and 31% of fish farmers used semi-pucca and pucca toilet respectively. Among 300 fish fry and fingerling traders 78% of traders have own house but only 22% of trader live in rental house or place. 46% of traders have institutional education that range from primary to higher education and other 54% of traders have no experience in education. In case of illness 58% of traders and trader's family goes to government hospital, 24% uses private clinic, 15% traders are uses local village doctor and another 3% does not get any treatment or not require no treatment. 93% traders have television, 5% house consist radio and another 2% house no instrument for entertainment. Only 10% trader wants their son and grandson engages with this fish fry and fingerling trading profession. The average monthly income of traders in the peak season is 18000 taka and off-peak season the income is less than 7000 taka per month.

The study was conducted on the livelihood approach of fry collectors at Shyamnagar upazila under Satkhira district. The objective of the study was to assess the present livelihood status, to identify the socio-economic condition and problem associated with the alternative livelihood approach of fry collectors. The survey was conducted on three unions of Shyamnagar upazila adjacent to Sundarban as study area. In the study area average family size was 5 persons per family. The maximum age level was 20-30 years old. Among the fry collectors 66% was male and 34% was female. Among them 62% was Muslim and 38% was Hindu. About 78% of total fry collectors are landless in the study area. Literacy was 31% of them where female literacy was 28% and male literacy was 72% and most of them can sign only. Most of the collectors about 63% lived in mud walled with golpata shed house. About 73% families have two earner and 68% have single family. Peak season of fry collection was March to May. For collecting fry they use push net, set bag net mainly. They collect fry in the early morning and in early evening for about 6-8 hours. Men collect 150-200 pieces of fry per day in peak season and 40-60 pieces of fry by women. Price varies from 800-3500 Tk. per thousand golda fry. Price is higher in the month on March-May. About 52% collectors engaged in fishing during off season as alternative income source. Their preferable alternative income source are sustainable agriculture, fry nursing, poultry farming, planned fish cultivation, cattle and goat rearing etc. The main problem of converting of fry collection to other profession was lack of other training of other works, lack of capital, poor infrastructure.facilities, absence of industrialization, lack of land, government and NGO level work is very limited.

AbstractRecent textile industry expansion has a major environmental impact if not addressed. Being a water intensive industry, textile manufacturing is usually associated with wastewater management challenges. Electrocoagulation (EC) is recognized as one of the effective solutions to address these challenges. This study aims to investigate the potential of integrating seawater into the EC process for textile wastewater treatment, targeting optimal pollutant removal efficiencies. A simple electrolytic reactor was designed to investigate the removal efficiency of these treatments for chemical oxygen demand (COD), total suspended solids (TSS), turbidity, and color from textile wastewater at different seawater percentages and retention times. Notably, the addition of seawater not only improves the EC process efficiency but also significantly dilutes pollutants, reducing their concentrations. This dual effect enhances removal efficiency and dilution optimizes the treatment outcome. The highest removal efficiencies were achieved for COD (47.26%), TSS (99.52%), turbidity (99.30%), and color (98.19%). However, pH, dissolved oxygen (DO), and electrical conductivity increased with increasing retention times and seawater percentages in the EC process. Moreover, Seawater − EC integration reduces power usage to 15.769 Am−2 and costs approximately 0.20 USD/m3. To assess the effects of the retention times and seawater percentages on pollutant removal from textile wastewater, an analysis of variance (ANOVA) was conducted utilizing the Design-Expert 11 software. The best model obtained using Central Composite Design (CCD) was quadratic for COD (R2 = 0.9121), color (R2 = 0.9535), turbidity (R2 = 0.9525), and TSS (R2 = 0.9433). This study suggests that higher seawater percentages and longer retention times effectively eliminate contaminants but increase ion concentrations.
The study was conducted the fish farmers in some selected area at sadar upazila in Jessore under the district of Jessore from September to December 2013. A total of 100 fishermen were selected by stratified random sampling method and interviewed. The average members of single family were 5-6 people per household. Single families were much more (62 %) than joint families. Most of the fish farmers were Muslims 92% and few of them were Hindus 8%Most of them had the secondary educational background and some of them with different levels of higher education. It was found that the number of school going children was 2-3 per house. Full katcha (17 %) houses were few, while the semi-pucca (40%) and pucca (43%) houses were more abundant. Regarding health and sanitation, 31% fishermen reported to suffer from gastric and 17% suffered from fever. Most of the interviewees were found to take credit facilities from different sources for the subsistence of their family and their venture. The 98% were found to have their tube-wells, others using Governmental tube-well, or those belonging to schools or neighbors However, they need more institutional, organizational, and technical and credit support for their better socio-economic and sustainable livelihood.

Wasiyyah wajibah (binding will) is legislated by the law for unprivileged grandchildren due to death of their father during the lifetime of grandfather whereas other grandchildren, i.e. cousins, stay solvent. Contemporary Muslim scholars disagree on the obligatory status and category of inheritors of wasiyyah wajibah as well as confusion appears over its consumption among Muslim society. Hence, this study using an analytical method, aims to examine the legitimacy of wasiyyah wajibah and its parameters. The most important finding of this study is that wasiyyah wajibah is legitimate due to grandchildren's sustenance and it is binding (wajibah) due to the authority of law as the judgment of ruler settles the dispute. Thus its legitimacy abides by the general principles of Islamic law. The study also concludes that the obligation of wasiyyah has been abrogated by the verse of inheritance only for the parents and relatives who inherit from the deceased's legacy, not for the parents and relatives who are deprived from the deceased. Wasiyyah wajibah shall abide by the fundamentals of wasiyyah in Islamic law and the deceased's volume of legacy will be the benchmark of the portion of grandchildren. Finally, wasiyyah wajibah signify the social justice and social solidarity of Islamic inheritance law (fara'id).
