Secara ekologis mangrove berperan sebagai daerah pemijahan (spawning grounds) dan daerah pembesaran (nursery grounds) berbagai jenis ikan, kerang dan spesies lainnya. Selain itu serasah mangrove berupa daun, ranting dan biomassa lainnya yang jatuh menjadi sumber pakan biota perairan dan unsur hara yang sangat menentukan produktivitas perikanan laut. Serasah yang sudah diketahui berat keringnya masing-masing sampel diambil 20 gram kemudian dimasukkan ke dalam kantong jaring berukuran diameter 15 cm dengan ukuran mata jaring 2 mm. Kantong tersebut diikat pada akar mangrove dengan posisi yang fleksibel atau saat surut, kantong tersebut terletak di lantai hutan dan saat pasang, kantong tersebut terapung di permukaan. Pengamatan terhadap makrobentos dilakukan di bawah tegakan mangrove  dengan membuat plot/jaring perangkap (trap) berukuran 5m x 5m selanjutnya dalam plot tersebut diletakkan tiga trap kuadran 1m x 1m secara acak untuk mengamati jenis makrobenthos. Mata jala yang digunakan dalam pembuatan perangkap/trap ini adalah 2 mm Hasil penelitian menunjukkan bahwa laju penghancuran serasah daun R. mucronata adalah paling lama (0,215 gram/hari)  dari ketiga jenis lainnya hal ini disebabkan kandungan tanin pada daun jenis tersebut (33,8%), pada daun R. apiculata (24%) dan daun S. alba (11,3%), sedangkan pada daun A. lanata memiliki kandungan tanin yang lebih rendah (0,44%) dan struktur daunnya lebih tipis hal ini menyebabkan serasahnya mengalami laju penghancuran (0,293 gram/hari) dan kehilangan nutrisi  lebih cepat. Fauna makrobenthos yang ditemukan dalam pengamatan terdiri atas 5 kelas yang terbagi dalam 21 jenis, yaitu Gastropoda 13 jenis; Bivalvia 4 jenis; Crustacea 2 jenis; Polychaeta dan Sipuncula masing-masing 1 jenis.
Telaah Kritis Teologi Islam Klasik Menuju Pemikiran Teologi Membumi
Authors: Surni Kadir  , Muhajirin  , Yulianti
Published: July 2023

Tulisan ini bersifat konstruksi paradigmatik pemikiran teologi Islam kritis. Untuk memahami konstruksi pemikiran tersebut, penulis mengemukakan berbagai pergeseran pemikiran teologi Islam sejak zaman klasik sampai sekarang. Pergeseran tersebut terjadi sejak zaman munculnya aliran Teologi Khawarij yang diskusinya seputar persoalan dosa besar, kafir, mukmin, surga, dan neraka. Kini, pemikiran teologi Islam sudah sangat berkembang dan memasukkan berbagai paradigma keilmuan yang bervariasi. Tema-tema diskusinya juga sudah sangat beragam, bahkan hal-hal baru yang belum pernah ada sebelumnya. Pemikiran teologi kritis adalah di antara paradigma baru yang sangat penting pada zaman sekarang ini. Telaah kritis teologi klasik ini bertujuan mengeluarkan manusia dari pemikiran yang hanya berkutat pada urusan ketuhanan yang tidak membumi menjadi memiliki prinsip ketuhanan yang seimbang dan membumi dengan memberikan rasa sadar untuk beramal soleh sebagaimana perintah dalam berbagai ayat Al-Qur’an dan hadis tentang memakmurkan bumi dengan giat penuh optimisme tanpa harus termenung berpangku tangan dengan tatapan yang tidak memiliki harapan.
Seed Hull Fracture Resistance of Upland and Pima Cotton Cultivars
Authors: Dowd Michael K. , Delhom Christopher D.
Published: July 2023

Seed durability is a current issue of cotton ginners, who have noted smaller and weaker seed, lower seed grades, and increased seed coat fragments within ginned cotton fiber. To better understand the differences in the seed hull properties of Upland (Gossypium hirsutum L.) and Pima (G. barbadense L) seed, compression testing was conducted to determine the seed hull fracture resistance of both species. Plants were grown in Five Points, CA, U.S., for two years. After roller ginning, seed were conditioned to standard environmental conditions and were compressed until rupture on a material strength tester. Seed of the Pima cultivars generally required greater maximum compressive force and energy to rupture than did the seed of the Upland cultivars. However, when the seed were compressed in a vertical orientation, a few individual Upland cultivars did have compression properties within the range of values observed for the Pima cultivars. Hence, it is possible to find Upland seed with compression properties comparable to or slightly greater than those of some Pima seed. Differences in the data for the two years showed that growing environment affects seed hull strength properties. The results should help clarify some conflicting literature regarding the relative strength attributes of Gossypium species seed.

Published: July 2023

In this paper, we discuss theoretically the behavior of ideal Bose-Einstein gases in a 3D box and in a harmonic trap. We make use of the mean filed theory based on the time dependent Gross-Pitaevskii equation which describes the main features of Bose-Einstein condensation. We investigate and discuss the density profiles and the ground state properties of a trapped condensate confined in harmonic trap. We found out that in an attractive interaction, the gas tends to increase its central density in order to lower the interaction energy.

Authors: RAVICHANDRAN JAYASHREE , MANICKAN ELANCHEZHIYAN
Published: July 2023

The Hepatitis C virus (HCV) infection is a global health concern. More than 70% of infections are life-threatening as it persists for a lifetime and leads to liver cirrhosis, chronic hepatitis, and hepatocellular carcinoma. The 30% of infections may get-ridden and provide long lasting protection. As the treatment with IFN- α and RBV therapy causes side effects, IFN- free DAA regimens has been developed recently and reported as beneficial. Nevertheless, vaccination would be the only way to eradicate the infection and to reduce the burden of HCV-related disorders. This article provides an overview of the virus-host immune response, vaccine development strategies, recent medications that have been licensed and delivered and vaccine development progress. The fundamental reason to develop the vaccination is to activate and to enhance the humans' natural defenses against HCV and thus preventing life threatening illness. Indeed, vaccination has proven to be the most effective and cost-efficient technique for preventing infections and their devastating consequences.

Authors: TEJASWINI ACHYUTUNI VENKATA NAGA , MALOTHU RAMESH
Published: July 2023

A vital step in drug discovery is structural and interaction assessment.  L-asparaginase is a highly used compound in various treatment regimens which includes combinational therapies. The application is not only limited to treating Acute lymphoblastic leukemia, where it is also found effective for myeloid leukemia and canine lymphoma. The study details about L-asparaginase of Streptomyces koyangensis (WP_203215894). Structural insights are obtained by evaluation with GalaxyTBM. The constructed 3D-model is based on L-asparaginase models belonging to Escherichia coli, Wolinella succinogenes and Helicobacter pylori. The Ramachandran assessment corresponds to 91.4% of residues in the favourable region while ProSA infers to -8.9 Z-score. Further, QMEAN4 score of -0.46, 92.903 ERRAT score as well as 100% of residues in agreement with Verify3D theory describe the quality of the protein to be good and acceptable. The protein is identified to be secreted in the cytoplasm as per subsequent CELLO version2.5. Docking studies involving L-asparaginase (WP_203215894) molecule with L-asparagine resulted in the lowest energy of -4.5 kcal/mol along with prominent active sites recognized by PyRx. Similar prediction in addition to -4.6 and  -4.8 kcal/mol is also resulted by CB-Dock. Further, the binding conformation referring to affinity of -4.5 kcal/mol is also supported by the interpretation of GalaxySite with identification of the same residues involved in ligand interaction. High values of affinity correspond to the analysis by SwissDock referring to -9.42 kcal/mol. The RMSF plot generated as part of protein flexibility analysis by CABS flex 2.0 depicted varied fluctuations however, the crucial residues interacting with the ligand are computed to have RMSF value < 2 represents rigidity. The therapeutic effectiveness of the enzyme has created interest in terms of tracing prospective sources and conducting computational analysis. The anticipated structure of WP_203215894 and derived assumptions are helpful and contribute valuable information for future in-vitro findings on L-asparaginase.

Status of lipid profile, trace elements and C-reactive protein (CRP) in Helicobacter pylori infected preeclampsia (PE) women were examined using patients attending Federal Medical Centre in Owerri, Nigeria. A total of 180 volunteer subjects within the ages of 18-40 years were recruited for the study. The volunteer subjects comprised of 60 PE women with H. pylori infection which served as group I, 60 PE women without H. pylori infection which as group II and 60 normotensive pregnant women (with no PE and H. pylori infection) which served as the control. Results obtained revealed varying levels of total cholesterol triglycerides, high density lipoprotein cholesterol (HDL-cholesterol), CRP, Cu and Zn observed among PE women with H. pylori infection compared to PE women without H. pylori infection and the control. Total cholesterol, triglycerides and CRP increased significantly (p<0.05) in group I subjects when compared to group II subjects and the control. Trace elements significantly (p<0.05) reduced in group I subjects against the control. The observation of the present study could be the status of PE women infected with H. pylori though there is need for further studies on this area to confirm the findings of the present study. This study has evaluated the lipid profile, trace elements and CRP status of H. pylori infected PE women.

Published: July 2023

The sudden death of thousands of Pseudotolithus elongatus in the first quarter of the year 2020 was an indication of elevated effluent contamination. The study was aimed at evaluating the human health risk of human exposure Polycyclic Aromatic Hydrocarbon (PAH)s to P. elongatus exposed to contaminants in Bonny River. Thirty-six P. elongatus and eighteen controls were sampled from the Bonny River in two seasons, (Wet season and Dry season) and analyzed for PAHs using Gas Chromatography - Flame Ionization Detector (GC-FID). Risk assessment of PAHs for the Dietary Daily Intake (DDI), carcinogenic potencies[(B(A)Pteq)], PAH4 index, Carcinogenic toxic equivalents (TEQ) and Excess Cancer Risk Index (ECR) was evaluated. DDI of PAHs indicates 1.4E-03 in Chrysene and Indeno (1,2,3) pyrene for wet season, and 1.1E-03 during the dry season. PAH4 revealed 0.065mg/kg in wet season and 0.23 mg/kg in dry season which are significantly above EU standard of 0.03mg/kg. B(A)Pteq in Dibenzo (a,h)anthracene (6.2E-02 and 0.22) were also higher than the EU standard. TEQs values were 0.23 mg/kg and 6.5E-02 were above the SV of 5.55E-03mg/kg which indicates potential toxicity. Result of the present studies indicates that there could be high potential PAHs human health risk associated with the consumption of Bobo Croaker (Pseudotolithus elongatus) from Bonny River.

Published: July 2023

This study was carried out over the period from June 2019 to May 2020. Its main objective was to monitor the seasonal dynamics of As, Cd, Cr, Cu, Fe, Mn, Hg, Pb, Ni and Zn in the waters of the lagoon area II of Ébrié system. To this end, the study of the seasonal dynamics of the temperature, pH, salinity, conductivity, transparency, dissolved oxygen content and TOC content of these waters, as well as the mean depth of this ecosystem, was also studied with the aim of approaching their implication in this process. With the exception of the TOC content determined according to NF EN 1484 standard and the trace metals contents obtained according to MA 203-Met ICP-MSMS standard in the lab, the other physical and chemical parameters were determined in situ in the water samples collected. The trace metals contents of these waters decrease from its dry season to its flood season. The marine water inputs would favour a relatively high presence of these trace metals in them in their dry and rainy seasons, due to their basic character and their relatively high transparency and salinity in these seasons. The waters of Comoé river would partially disadvantage this process in its flood season, due to the slightly acidic character and low transparency and salinity of these waters in this season. Over all the study period, the relatively high temperature, conductivity, and oxygen content of these waters would have been conducive to the presence of these trace metals in dissolved form in them through the decomposition of organic matter. The relatively important organic matter content of these waters and the relatively shallow depth of this ecosystem would have disadvantaged this process over all the study period.

To determine the effects of environmental factors on rhizobia strains associated with some selected leguminous weed species, rhizobia strains isolated from root nodules of five weed species (Mimosa pudica, Crotolaria retusa, Desmodium triflorum, Canavalina ensiformis, Stylosanthes spp.) were subjected to varying temperature, salinity, and pH in the laboratory. Results indicated better growths at temperatures of 30 and 370C compared to the temperature of 250C.  Results further showed that microbial growth was optimal at 1.5% salt concentration. Optimum growth was also obtained at the pH range of 5 and 8. The study further revealed by a series of morphological and biochemical tests that all the strains were gram-negative, rod-shaped, and mucous producing. Rhizobia strains from leguminous weeds were found to exhibit faster growth than the strain nodulating soybean in all the conditions to which they were subjected. A cross inoculation study was therefore recommended to access the compatibility of these rhizobial strains from the wild with cultivated leguminous plant species.

Climate change is common phenomena in Ethiopia which affects the livelihood of millions of the rural community. An increase in temperature, fluctuation of rainfall intensity and frequency induces extreme environmental impacts through drought and floods. This study was conducted on three villages/ kebeles in Asagirt District of North Shewa Zone, Amhara Regional State. The objective of this study was to analyze community perception on existence of climate change and its impact on socio-economic activities for designing local level adaptation and mitigation strategy. Both primary and secondary data were analyzed to generate information. Simple systematic random sampling techniques were employed to select 121 household heads and purposive sampling was employed for data collection from 28 Key informants and 21 focus group discussant. Findings of our study indicated that men households which are adolescence in age are the main components of the community categorized as illiterate have good perception and awareness on the existence of climate change. The analyses of 28 years climate pattern showed that the average temperature has increased by 0.99ºC for with corresponding annual increment of 0.033ºC. Similarly, there was higher yearly trend of fluctuation in rainfall pattern between 1989 -2018 in which the average annual rainfall is 891 mm. Findings of the study indicated that mixed farming as the dominant type agricultural practice was highly affected by climate change reducing crop productivity and animal production. Findings of our study have also indicated that even though the impact of climate change is imminent which affected water availability in all districts, the forest cover has increased in all villages because of afforestation interventions. Hence, results of present study draws conclusion of for designing local adaptation and mitigation strategies including small-scale irrigation, tree planation, climate smart agriculture  area ex-closure, integrated soil management using organic fertilizer for increasing above and below ground carbon sequestration to  manage the local micro climate and build the livelihood and strengthen community resilience.

Water, as an excellent solvent, dissolves minerals in the geological system. Several factors, such as chemical weathering of the rocks, influence the physicochemical nature of groundwater. Because of the presence of contamination in groundwater, people living in metropolitan cities are more likely to suffer from certain health problems. The current study was carried out to examine the various groundwater parameters in five suburban area of Asan River (Chandrabani, Badowala, NayagoanMallan, Parval Village and Herbertpur) Dehradun, and to check its fitness for drinking. Eight water quality variables/parameter (pH, TDS, Alkalinity, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride, Nitrate) were selected for this analysis. Twenty samples of groundwater were collected from the five sampling sites by using 1 litre sterile polyethylene bottles during a period of six months. The pH and TDS were estimated by Digital soil and water analysis kit, alkalinity, chloride, total hardness (Ca &Mg) was determined by titration methods. The formula was used to calculate the total suspended solid. The concentration of nitrate in ground water samples was determined using a spectrophotometer. The results of the analysis were compared to the BIS standards for drinking water (IS 10500:1991). Further, the groundwater was classified on the basis of Freez and Cherry [1], Sawyer and Mccarty [2] and Stuyfzand's Classification.

Published: July 2023

The success of any microalgal research involves effective methods for sampling environments, isolation, purification and the maintenance of algal strains. The isolation of soil microalgae poses a great challenge since the soil is a home for thousands of different species, including algal species, bacteria, viruses and fungi. As such cultures are susceptible to contamination, which may interfere with algal structure, biomass yield and the erroneous identification of species for molecular genetic analysis. The most common methods for isolation and purification of microalgae are the single cell isolation, serial dilution and a streak plate. This procedure is tedious, time consuming, demands precision and expertise and may not yield results. Thus in the present study, an attempt was made to modify these methods for the isolation of soil microalgae. With the modification, three microalgal sp. were isolated, purified and identified (viz Chlorella vulgaris, Microcystis aeruginosa and Scenedesmus obliquus) in a simplified manner.

Published: July 2023

Stewardship programs are gradually being phased out in favor of Extended Producer Responsibility (EPR) schemes, which are used in various forms in different Canadian provinces. An example is the British Columbia province's EPR program on empty plastic beverage containers. Provinces like Saskatchewan and Alberta, on the other hand, continue to rely on stewardship programs and are in the process of incorporating the EPR policy as a program into their waste management regulations. Therefore, this study will discuss how stewardship program policies have helped to solve a portion of the plastic waste problem; however, negotiations to fully integrate the EPR program into Saskatchewan and Alberta waste management policies are still ongoing. The significance of this study has demonstrated how stewardship programs in Saskatchewan and Alberta have promoted the reuse and recycling economy of plastic management to a limited extent in these respective provinces. A case study method was used to analyze and investigate the stewardship program, with a focus on plastic bottle management. Field observations were conducted at selected recycling companies (Sarcan recycling and Alberta beverage container recycling corporation) in Saskatchewan and Alberta to correlate the data gathered during the investigation, as presented in this research outcome. Implementing the EPR program, according to the study's findings, may be the most effective way for Canada to achieve a circular economy of plastic waste management.

Malawi has registered a big number of maternal deaths and newborn or birth complications over the years.  This is prevalent in many rural areas and villages across the country. The reason behind these maternal deaths and newborn complications is delayed access to early Antenatal Care visits (ANC). ANC is distinct and special care given to pregnant women to ensure improved health outcomes i.e., to avoid maternal deaths and newborn complications. Chiphwanya Health Centre which is found in Dedza district, the central region of Malawi, is well vested in this task. This research study was, therefore, conducted to assess factors leading to delayed access to ANC care in Maganga Village which surrounds the aforementioned health centre. The study adopted a mixed-method where both qualitative and quantitative data were collected and analysed. Quantitative data were collected from pregnant women while qualitative data was collected from guardians and health personnel. The results indicate that 43% of women and 50% of stakeholders considered traditional beliefs as the key contributor to delayed access to ANC. Over 20% of pregnant women and 6.7% of key stakeholders attributed distance as a reason for delayed access to ANC services. It can be concluded that delayed access to ANC portrayed in this area is due to traditional beliefs and distance. Hence, the need for awareness campaigns so that the community is well informed of the importance of ANC and the local leaders should have a touch on issues regarding ANC.
