Abstract: Fifteen (15) water samples were collected from Wupa river, with five (5) each from the upstream, downstream and point of effluent discharge into the river and screened for the presence of enteropathogens. Results of the total aerobic bacterial loads upstream ranged from 1.06×10⁹±0.20 Cfu/ml to 1.23×10⁹±0.21 Cfu/ml while the coliform ranges from 2.65×10⁸±0.21 Cfu/ml to 2.9×10⁸±0.28 Cfu/ml. However, the total aerobic bacterial loads at the point of effluent discharge to the River range from 8.20×10⁸±0.28 Cfu/ml to 9.40×10⁸±0.22 Cfu/ml while the coliform ranges from 2.10×10⁷±0.11 Cfu/ml to 2.40×10⁷±0.14 Cfu/ml. A total of thirty-nine (39) enteropathogens belonging to six bacterial genera and six species were isolated from this study and they are Escherichia coli, Salmonella enterica, Salmonella typhimurium, Proteus mirabilis, Klebsiella pneumonia, Enterobacter cloacae and Oblitimonas alkaliphila. Ten bacterial isolates belonging to five strains were isolated from the upstream station of Wupa River which was nine (9) enteropathogens belonging to five (5) strains were isolated from the point of effluent discharge to the river while, the downstream of wupa river after effluent discharge point recorded the highest number of enteropathogens of twenty (20) with eight (8) strains of bacteria isolates. Escherichia coli was the most frequently isolated bacteria which represented 25.64%, followed by Klebsiella pneumoniae which represented 15.38% of the total isolates. Salmonella enterica serovars Eko EQAS2016S1 was 12.81% while Proteus mirabilis RCFS3, Salmonella Typhimurium FDAARGOS_319, Oblitimonas alkaliphila E1148 and Enterobacter cloacae EMP 13-3 recorded 10.26% each, whereas Proteus mirabilis ALK044 recorded 5.13 % being the least number of isolated bacteria. Although the bacteria isolated from the downstream was significantly high (P≥ 0.05), yet there was no significantly difference (P≤ 0.05) between the bacteria load isolated from the upstream and downstream as well as that of the effluent discharged into the river. However, there is an urgent need for for proper treatment, management, monitoring and sanitation of the effluent to avoid the transfer of enteropathogenic bacteria into the receiving water body.

Abstract: Industrial wastewater is one of the important pollution sources in the pollution of the water environment. Effluent streams from food processing may have a high biochemical and chemical oxygen demand (BOD and COD) resulting from organic wastes entering into the wastewater stream, and from the use of chemicals and detergents in various processes including cleaning. In addition, effluent may contain pathogenic bacteria, pesticide residues, suspended and dissolved solids such as fibers and soil particles, nutrients and microbes, and variable pH. In this study, experiments have been conducted to evaluate the pollution in industrial food wastewater and treated by using new technique, samples were collected during 2016 from the raw wastewater of Senyoreta potatoes and snacks factory in Tanta, El Gharbya governorate, Egypt. The samples were analyzed following standard procedures for the determination of: chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total suspended solids (TSS), total nitrogen (Total-N) and total phosphorus and other parameters. The results indicated that the quality of wastewater is very high concentrated with pollutants. The pilot plant was designed to perform treatment with high efficiency removal so we constructed modified MBBR process.

Abstract: Background: Species richness and diversity of insects were investigated in an agro-ecosystem in Bhabar region of Uttarakhand from March 2018 to February 2020. Results: In total, 992 individuals were collected representing 7 orders (Lepidoptera, Coleoptera, Hemiptera, Hymenoptera, Orthoptera, Diptera and Odonata), 30 families and 91 species that included herbivores, predators, omnivores and saprophages. The most dominant order was Lepidoptera with a relative abundance of (46.15%) and, the least was Diptera (6.59%). The five most abundant families by numbers of individuals were Pieridae (14.8%), Nymphalidae (13.9%), Lycaenidae (6.1%), Papilionidae (5.9%), and Libellulidfae (5.4%). The five most diverse families by species were Nymphalidae (13), Pieridae (9), Lycaenidae (8), Papilionidae (7), and Libellulidae (6). Conclusions: The diversity index showed significant Diversity (Hʹ=1.832), Evenness (E=0.9449) and Margalef species richness (d=2.076) of insect fauna. Diversity indices of insect orders showed that Lepidoptera was the most diverse (Hʹ=1.641), Dipterans had highest Evenness (E=0.9449), and Coleopterans had the maximum species richness Margalef’s Index (d=2.056). There were 720 individuals of insect pollinators visitors were observed, which belonged to 62 species in 4 orders (Lepidoptera, Coleoptera, Hymenoptera, and Hemiptera).

Abstract: Australian monsoon is a key system in  global monsoon systems. I have conducted many scientific researches on this monsoon system  and as a part these researches, I proposed and designed the Basics of Australian Monsoon Time Scale  which can help to study the past, present and future movements and conditions of the Australian monsoon. In the current year 2022, the pre-path of Indian summer monsoon was traveling upwards and reached to the 29th June. Below this, the main-path of Indian summer monsoon also traveled upwards parallel to the pre-path of Indian summer monsoon with a difference of about 30 days and reached to the 29th July, As it moves further up, changes in the climate are likely increasing and there are more chances of heavy rains and floods in the coming years.
