Health status of a snakehead (Channa punctatus) of two fish markets in Mymensingh, Bangladesh

An experiment was carried out for a period of six months during October 2008 to March 2009 to investigate the health status of a snakehead, Channa punctatus through clinical and histopathological technique. Fish were collected from two fish markets of Mymensingh district. Clinically and histopathologically, it was observed that fishes from both the markets were healthy in October and March but moderately affected in November and February. In the months of December and January, 7.5- 8% of the fishes were affected clinically and showing various clinical signs like, discolouration, deep ulcer, ill health, scale loss and rough skin. Histopathologically, in the month of December and January, major observed pathologies of skin and muscle were necrosis, vacuums, fungal granuloma and loss of dermis. Gills were affected having parasitic cysts, monogenetic trematode, clubbing, loss of primary and secondary gill lamellae, hemorrhage, necrosis and hypertrophy. Vacuoles, pyknosis, hepatic necrosis, hemorrhages and fungal granuloma were observed in liver. Renal pathology included necrosis and pyknosis of kidney tubules, hemorrhages, presence of bacterial colony and vacuoles. From present findings, it was found that, fishes from urban market were more affected with diseases than pre-urban market especially in the months of December and January when compared with other months. From overall observation, C. punctatus were severely affected by epizootic ulcerative syndrome (EUS), dactylogyrosis, protozoan and bacterial diseases during colder months of the year

Ethnic Association in Primary Systemic Vasculitis: A Systematic Review

Background: Literature described wide disparities in incidence and prevalence between different types of vasculitis. There were no comprehensive studies on ethnic or racial associations in all types of primary systemic vasculitis (PSV) in any published article, until this review commenced in 2020. The purpose of the review is to synthesize the evidence regarding the relation of ethnicity and the incidence and/or prevalence of different types of PSV. Methods: A total of 52 selected articles which include Clinical trials, cohorts, cross-sectional studies, case series, and case studies and have been published within the last 10 years in the human population, were reviewed by searching The Medline, PubMed, and Google Scholars databases using predefined keywords. The PRISMA diagrams were followed to identify relevant articles. The methodological qualities of the studies were assessed using the EPHPP tool. Finally, a summary of the evidence on the association between ethnic origin and PSV was painstakingly compiled. Results: The connection between ethnicity and different types of PSV has been found to be significantly diverse in this research such as vasculitis is more common in Asians and Scandinavians, Kawasaki disease and periarteritis nodules are more prevalent in Japanese and Alaska-natives, ANCA-associated vasculitis is more frequent in Caucasians, whereas Henoch-Schonlein purpura and Cogan syndrome more usual in Caucasians and Asians. Furthermore, Behçet's disease more commonly occurs on the "Silk Road", especially in Turkey. Conclusion: Genetic susceptibility and environmental elements could be the contributing factors to the global variation in the incidence and prevalence of primary systemic vasculitis

Analysis of different scenarios for residential energy management under existing retail market structure

This paper presents an analysis of a residential energy management scheme under existing retail market structure with the integration of solar photovoltaic (PV) and battery energy storage systems. In this paper, different scenarios are analyzed with an aim of achieving the most cost-effective solutions for the integration of solar PV and battery energy storage systems. The main idea behind these analyses is to obtain a grid independent residential energy management system through the reduction of purchasing energy from the existing power grid. The results from the analysis of different scenarios for a typical Australian house demonstrate that the shortage of energy during the high loads and excess of energy during the higher output of solar PV system can be reduced with the design of a proper energy management scheme employing a transactive energy management framework

Comprehensive economic evaluations of a residential building with solar photovoltaic and battery energy storage systems: an Australian case study

This paper presents a comprehensive framework for conducting economic analysis of a residential house along with the integration of solar photovoltaic (PV) units and battery energy storage systems (BESSs). The proposed framework is developed by considering different tariff structures of the existing energy market as well as the investment costs for the solar PV units and BESSs. In this paper, the economic evaluations are carried out based on different economic measures such as replacement cost, electricity bill, simple payback analysis, net present value, discounted payback analysis, and levelized cost of energy along with the reduction in carbon di-oxide (CO2) emissions and grid independency. The proposed framework is implemented on an Australian residential building by considering different real-time operating scenarios. The results from the analysis demonstrate the profitability of a residential building for the investment on solar PV units and BESSs

Investigation on health condition of a freshwater eel, Monopterus cuchia from Ailee beel, Mymensingh, Bangladesh

The health conditions of freshwater mud eel, Monopterus cuchia of Ailee beel, Mymensingh district was investigated through clinical and histopathological observations from September 2005 to March 2006. Monthly sampling of water quality parameters like temperature, dissolved oxygen, pH and total hardness were carried out. Water temperature and total hardness were at reduced level for fish during the months of November to January in the beel. Clinically weak body, rough skin, deep ulcer and grey brownish colour of the body were noticed especially from November to January. Major pathology in the skin and muscle such as loss of epidermis and dermis, necrosis of myotoms, huge vacuum spaces, marked melanomacrophage and fungal granuloma were found in December and January. Marked melanomacrophages, severe haemorrhage, vaccums, hepatic necrosis, fat droplets were found in the liver. In kidney numerous haemorrhagic areas, necrosis, few fat droplets and many fungal granulomas were seen in December and January. Histopathologically, sampled fishes were found normal in September and October and reduced pathological signs were observed in February and March. Clinically and pathologically eels were found to be more affected in December and January. Reduced temperature and total hardness might have played role in the occurrence of clinical and pathological changes in fish during the period. The fishes were affected by EUS, with the evidence of development of fungal granuloma in skin, muscle and kidney

Effects of different level of starter culture and sugar on manufacturing characteristics of Misti Dahi (Sweet Yoghurt)

The research was undertaken to know the effects of different level of sugar and mixed culture on qualitative characteristics of dahi. Milk samples were collected and boiled to reduce the 20% of their volume and divided into four portions after boiling. Sugar was added at 8, 10, 12 and 14% of of milk and boiled again for a while. After boiling milk samples were cooled down to 370 C and 1, 2, 3 and 4% mixed culture was added in each of the four level sugar added milk. The combination of 4 × 4 = 16 samples were prepared and were incubated at 370 C in an incubator until coagulation. From the organoleptic evaluation it was found that dahi samples prepared by adding 10 and 12% sugar level obtained more score then that of the 8 and 14% sugar added dahi samples. Culture level and sugar level both had influence on coagulation time. Coagulation time was less when low sugar and high level of culture was used, on the other hand coagulation time was more when high level sugar and low level culture was used. Chemical analysis showed that total solids and solids-not-fat, protein, carbohydrates content of dahi samples were significantly increased due to the increased level of sugar and culture. But on other parameters effects of sugar and culture were not appreciable. It was concluded that sugar level and culture level both can changes the quality of dahi samples. A combination of 10% sugar with 2% culture and 12% sugar with 3% culture was found appropriate for dahi making

Synthesis and characterisation of CdSe QDs by using a chemical solution route

An efficient synthesis process approach based on a chemical solution route is developed for the cadmium selenide quantum dots (CdSe QDs) that utilise photonic and optoelectronic device manufacturing. The developed route consists of dissolving the cadmium chloride (CdCl2.H2O), 2-mercaptoethanol and sodium selenide anhydrous (Na2SeO3). The different characterisation parameters such as ultraviolet (UV) absorbance, x-ray diffraction (XRD), scanning electron microscopy, energy dispersive x-ray and transmission electron microscopy (TEM) were employed in order to develop the CdSe QDs. When the sample was analysed from the UV–visible studies, the bandgap was about 2.16 eV, whereas the bulk CdSe bandgap was about 1.78 eV. The developed CdSe QDs possessed a cubic crystal structure with crystalline dimensions of about 4.86 nm. Its surface morphology and structure showed the smooth appearance of the surface. The result indicated agglomerated spheres. Ultimately, according to XRD and TEM results, the crystalline dimension was determined in good agreements. © The Institution of Engineering and Technology 202

Drivers of child and women dietary diversity: Empirical evidence from a peri-urban area of Bangladesh

Dietary diversity (DD) is considered an indicator of micronutrient adequacy for all age groups. An unbalanced diet that contains only one or two nutrient components can be fatal. Given that women make up half of our population and that children are a country's future, it is crucial to maintain the nutritional status of both groups. Thus, the current study was designed to analyze the factors affecting the dietary diversity of both children and women of the residents living in a manufacturing industry-dominated growing peri-urban area of Bangladesh, where an institutional huge vacuum exists, mainly due to administrative transition. We randomly selected 146 mothers who had at least one child between the ages of 6 and 59 months to participate in our data collection. To identify the factors that influence children's and women's dietary diversity, multinomial and binary logistic regression models were used, respectively. Results unearthed that the age of the children, maternal age, and maternal education significantly affect children's dietary diversity, while the mother's education level, as well as their access to and control over resources affect their own dietary diversity. The study concludes that education has multiple effects on women's and children's dietary diversity as it can help mothers to make decisions about how the distribution of time and resources should be prioritized. Again, greater access to and control over resources may enable mothers to take care of any urgent needs for their children. For a sustainable solution, the policy level needs to keep its eyes on the girls' quality education as potential future mothers. © 2024 The AuthorsOpen access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
