The GC i.e Green chemistry revolution is the revolution that delivers a huge number of complications and challenges to those that are practicing chemistry in industries also in education and research. The start of green chemistry is taken into account as a response to the necessity to scale back the damage of environment by man – made materials and therefore the process wont to produce them. Green chemistry could include anything from reducing waste to even removing waste in correct manner. All chemical waste should be disposed of within the absolute best manner without causing any damage to the environment and to the living beings. Green chemistry which is that the latest and one among the foremost researched topics now days has been in demand since 1990’s. Majority of research in green chemistry aims to scale back the energy consumption required for the assembly of desired product whether it's going to be any drug, dyes and other chemical compounds. It aims to scale back or maybe eliminates the assembly of any harmful bi-products and maximizing the specified product without compromising with the environment.

Authors: Akter Romana , Hossain KS , Bashar MA 
Published: April 2020

Antagonistic potentials of seven rhizoshere soil fungi viz., Aspergillus flavus Link., A. fumigatus Fresen., A. niger Tiegh., A. terreus Thom., Penicillium sp., Trichoderma harzianum Refat. and T. viride Pers. were tested against the Fusarium oxysporum Schlecht. and F. solani (Mart.) Sacc. – the two pathogens, isolated from wilted roots of brinjal plants. Out of seven soil fungi Trichoderma harzianum was found most effective to control the growth of both the test pathogens. More than 50% inhibition of the test pathogens were observed with T. viride, Aspergillus niger and A. fumigatus in colony interaction. The maximum inhibition of radial growth of the test pathogens was observed with volatile metabolites and cell free culture filtrates of Trichoderma harzianum. This fungus may be exploited commercially to control the disease.

Published: April 2020

Effects of four different feeds on growth and nutrient composition of mrigal fingerlings (Cirrhinus mrigala) were evaluated. After 30 days of rearing growth parameters and quality of fish flesh were examined. During the rearing period, the change in growth and feed utilization by the mrigal fed with feeds have been assessed as condition factor (K), average daily gain (ADG), specific growth rate (SGR) and feed conversion ratio (FCR).The highest FCR (6.23 ± 0.59) was found in the treatment 4 while the lowest (3.08 ± 0.10) in the treatment 1. The condition factor was highest (0.89 ± 0.01) in treatment 1 while the lowest (0.81 ± 0.05) in the treatment 4. After 30 days of rearing, moisture content of mrigal in different treatments was 77.2, 78.41, 76.99 and 77.86% in treatments 1, 2, 3 and 4, respectively. Protein was 17.15, 15.89, 16.90 and 14.76% in treatments 1, 2, 3 and 4, respectively. Lipid was 2.07, 2.22, 2.25 and 2.85% and ash content was 3.58, 3.48, 3.88 and 4.53% in four (1, 2, 3 and 4) treatments, respectively.

Effects of Sulphur Deficiency on Accumulation of K+, Na+, NO3-, PO43- and transport of K+, Na+ in mungbean (Vigna radiata L. var. BARI MUNG-6)
Authors: Saha Shukanta , Samad Rifat , Rashid Parveen , Karmoker JL 
Published: April 2020

Sulphur deficiency caused a decrease in accumulation of Na+ but increased the accumulation of K+ in the root, stem and leaf of mungbean seedlings grown in solution culture under light bank. It also decreased K+ and Na+ accumulation in the root, stem and leaf of mungbean plants grown in sand culture under natural environmental conditions. However, sulphur deficiency increased the accumulation of NO3- in the root and stem but decreased that in leaf of mungbean seedlings grown in solution culture. It decreased accumulation of PO43- in the root, stem and leaf except an initial increase in the leaf. It increased net influx, long distance transport and transport index of K+ but decreased those of Na+ in mungbean seedlings. This result indicates that K+ is more mobile in plants than Na+.

Authors: Rabbane Md Golam , Rahman Md Rakibur 
Published: April 2020

This study evaluated the effects of five diets (diet 1: Dried tubifex, diet 2: Artemia, diet 3: Artemia and commercial pellet feed, diet 4: Spirulina and commercial pellet feed; diet 5: commercial pellet feed) on growth, reproductive performances and embryogenesis of zebrafish Danio rerio for a period of 62 days. Significantly higher specific growth rate was found in diet 5 when compared with diet 1 but no significant difference was observed between diet 2, 3, 4 and 5. Mean weight and length gain were significantly greater in zebrafish fed diet 5 than diets 1 ‐ 4. While 100% survival was found in diet 4, the lowest level was 90.26 ± 1.06% in diet 1. Mean spawning success was significantly higher in zebrafish fed diet 5 than in those fed diets 1 ‐ 4. Mean fertilization and hatching rates were higher in the fish fed diet 3 ‐ 5 than in diets 1 and 2. Zebrafish consumed commercial pellet feed only resulted in more viable offsprings and grown better. Results suggested that commercial pellet is suitable in zebrafish culture for maximum growth and production of viable offspring in laboratory condition.

Assessment of heavy metals and thermal properties of soil‐rice‐husk system collected from three districts of Bangladesh
Authors: Yasmin Farzana , Sultana Rajia , Sultan Md Zakir 
Published: April 2020

This study was conducted to evaluate the contamination of heavy metals and their thermogravimetric properties in the soil-rice-husk system. Heavy metals concentration was determined by Atomic Absorption Spectroscopy (AAS) and thermal property was also analyzed by using Thermo Gravimetric Analyzer (TGA). Metals uptake in rice crop grown in soils of three different areas (Savar, Chapainawabganj and Gazipur) in Bangladesh was studied. Soil, rice husk and rice samples were analyzed after microwave acid digestion. Heavy metals concentration detected in rice samples decreases in the following order as Fe > Mn > Zn > Cu > Ni > Co > Cd > Pb. The metal content in husk was higher than in corresponding rice. Fe concentration was higher than other metals in soil, husk and grain samples. The concentrations of Cd and Pb in the soil were found to be below the detection limit and the order of the other heavy metals as Fe > Mn > Zn > Cu > Ni. The thermal properties of the soil-ricehusk system did not show any significant visible variation during this experiment except for the soil of the Gazipur areas. The residual mass obtained from the TG thermogram helps to make a relation between the quality of soil and the rate of uptake of heavy metals by rice or its husk.

Authors: Alam Mohammad Shamimul , Hoque Md Nazmul , Akter Mousumi , Md Shahjahan Reza 
Published: April 2020

Samples of Drosophila species were collected from some selected sites (viz., Dohar Upazila of Dhaka Division, Hironpoint of the Sundarbans, Satchori of Sylhet Division) of Bangladesh and these were cultured in the laboratory to study developmental stages, external morphological traits and sex comb. They were identified as D. melanogaster, D. ananassae and D. bipectinata. The sex comb teeth number and arrangement were distinct for all three species. D. melanogaster had one row of 10 - 11 teeth in the sex comb. D. ananassae had eight rows of teeth in the sex comb possessing 32 - 33 teeth in total. D. bipectinata had 2 - 3 rows of teeth in the sex comb and total teeth number varied from 11 to 15. Among three species, sex comb teeth number of D. bipectinata varied most. Eleven different patterns (n=20) in sex comb were observed in D. bipectinata indicating significant diversity within species. Variation in pupation sites among three species was also observed in the laboratory condition. D. bipectinata pupated on the food medium, whereas other two species pupated on the vial wall. Thus, diversity among these three species of Drosophila was documented which could be utilized as bioindicator in future.

Published: April 2020

A total of 24 species of fungi, namely Aspergillus flavus Link, A. fumigatus Fresenius, A. niger (Type 1 and Type 2) Van Tiegh, A. ochraceus K. Wilhelm, A. nidulans Eidam, Aspergillus sp.1, Aspergillus sp.2, Aspergillus sp.3, Curvularia lunata (Wakker) Boedijn, Colletotrichum gloeosporioides Penz & Sacc, C. gossypii Southw., Chaetomium globosum Kunze., Fusarium nivale (Fr.) Sorauer, F. moniliforme J. Shelden, F. oxysporum Schlechtendal, F. fujikuroi Nirenberg, Mucor sp. P. Micheli ex L., Penicillium sp.1 and sp.2 Link, Rhizoctonia solani Khun., Rhizopus stolonifer (Ehrenb.) Vuill., Rhizomucor sp. Lucet & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. were found to be associated with the seeds of 14 varieties (CB 1- CB 14) of cotton. Out of these 24 fungal species, nine were found to be pathogenic to cotton. They were Aspergillus flavus, A. niger (Type 1), Aspergillus sp. 1, Colletotrichum gloeosporioides, Curvularia lunata, Fusarium nivale, F. moniliforme, Mucor sp. and Rhizoctonia solani. These pathogenic fungi had remarkable effect on seed germination, vigor index, root-shoot length and mortality of cotton seedlings. The germination percentage of control seeds was 88 but because of the presence of pathogenic fungi the rate showed considerable reduction in all the varieties and it varied from 20 to 82%. Among the nine fungal isolates Rhizoctonia solani showed maximum reduction in seed germination. Aspergillus flavus, Colletotrichum gloeosporioides and Fusarium moniliforme also caused near about 50% reduction in seed germination. Mortality percentage of control seedling were also less (6) whereas, in inoculated seeds it was higher and varied from 7 - 23%. Root- shoot ratio of control seedlings was high but less in inoculated seedlings. The vigor index of control plant was high (1548.8) but less in inoculated plants. The lowest vigor index was noticed for Rhizoctonia solani (202.0) and highest for Aspergillus sp. 1(1213.6). Results indicated that Curvularia lunata and Rhizoctonia solani showed a greater impact in reduction of cotton seed germination and vigor index.

Penerapan prinsip Good Corporate Governance (GCG) mengarahkan perusahaan untuk membentuk tata kelola manajemen perusahaan yang bersih, transparan, dan professional. Penerapan prinsip GCG di Indonesia masih tergolong rendah, berakibat pada munculnya salah satu kasus yaitu mengenai Sriwijaya Air Travel Pass (SJTP). Tujuan penelitian ini adalah untuk mengetahui mengenai penerapan prinsip-prinsip Good Corporate Governance (GCG) terkait Perjanjian Sriwijaya Air Travel Pass (SJTP) dan apakah penerapannya sudah sesuai dengan Undang-Undang Nomor 40 Tahun 2007 tentang Perseroan Terbatas dan pengaturan lainnya, dan menganalisis akibat hukum apabila tidak diterapkannya prinsip tersebut di PT. Sriwijaya Air. Metode penelitian yang digunakan di dalam penulisan skripsi ini adalah menggunakan metode pendekatan yuridis implementatif, yaitu metode penelitian hukum yang mencari kesesuaian fakta di lapangan dengan peraturan yang mengaturnya, dalam hal ini prinsip Good Corporate Governance (GCG) di dalam Undang-Undang Nomor 40 Tahun 2007 tentang Perseroan Terbatas yang akan menjadi dasar yuridis terkait perjanjian keanggotaan Sriwijaya Air Travel Pass (SJTP) serta peraturan perundang-undangan lainnya. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa maskapai Sriwijaya Air belum menerapkan prinsip Akuntabilitas (Accountability) dan prinsip pertanggungjawaban (Responsibility) Good Corporate Governance (GCG) di dalam peraturan internal perusahaan dan secara otomatis tidak pula diterapkan di dalam perjanjian Sriwijaya Air Travel Pass (SJTP) sehingga pihak maskapai Sriwijaya Air memiliki kewajiban untuk memberikan ganti kerugian kepada konsumen/anggota Sriwijaya Air Travel Pass (SJTP).

Published: April 2020

Background: As part of needs assessment processes, our Faculty of Medicine (FOM) continuing professional development office investigated the differences between physicians who do and those who do not frequently participate in planned group learning to gain insight into their interest in new forms of continuing professional development (CPD).Method: We sent a 19 item questionnaire to 485 randomly selected physicians of the 1050 family physicians in Eastern Ontario. The questionnaire examined present participation and satisfaction with CPD activities and perceptions regarding the potential impact of those; and appetite for new opportunities to meet their learning needs.Results: Of the 151 (31%) physicians responding, 61% reported attending at least one FOM group learning program in the past 18 months (attenders) and 39% had not (non-attenders). Non-attenders indicated less satisfaction (p = 0.04) with present opportunities and requested development in newer approaches such as support for self-learning, on-line opportunities, and simulation.Conclusions: Although there are high levels of satisfaction with the present CPD system that predominantly offers large group learning options, a substantial number of physicians expressed interest in accessing new options such as personal study and on-line resources.

Published: April 2020

Background: The use of high-fidelity simulation is emerging as a desirable method for competency-based assessment in postgraduate medical education. We aimed to demonstrate the feasibility and validity of a multi-centre simulation-based Objective Structured Clinical Examination (OSCE) of resuscitation competence with Canadian Emergency Medicine (EM) trainees.Method: EM postgraduate trainees (n=98) from five Canadian academic centres participated in a high fidelity, 3-station simulation-based OSCE. Expert panels of three emergency physicians evaluated trainee performances at each centre using the Queen’s Simulation Assessment Tool (QSAT). Intraclass correlation coefficients were used to measure the inter-rater reliability, and analysis of variance was used to measure the discriminatory validity of each scenario. A fully crossed generalizability study was also conducted for each examination centre. Results: Inter-rater reliability in four of the five centres was strong with a median absolute intraclass correlation coefficient (ICC) across centres and scenarios of 0.89 [0.65-0.97]. Discriminatory validity was also strong (p < 0.001 for scenarios 1 and 3; p < 0.05 for scenario 2). Generalizability studies found significant variations at two of the study centres.Conclusions: This study demonstrates the successful pilot administration of a multi-centre, 3-station simulation-based OSCE for the assessment of resuscitation competence in post-graduate Emergency Medicine trainees.
The Show Cave at “Gran Caverna de Santo Tomás” (Pinar del Rio Province, Cuba)
Authors: Parise Mario , Valdes Suarez Manuel 
Published: April 2020

Del jame Gran Caverna de Santo Tomàs, ki je eden najdaljših jamskih sistemov na Kubi, je urejen za turizem že od 1994. To je šesti nivo (od sedmih) tega kompleksnega kraškega sistema, katerega najnižji del je aktiven in teče skozenj potok Arroyo Santo Tomàs. Zaradi velike pestrosti kraških oblik, tako na površju kot v jami in zaradi pomembnih arheoloških odkritij, je jamo Gran Caverna de Santo Tomàs v zadnjih 10 letih obiskalo pomembno število turistov in znanstvenikov, kljub težavam zaradi oddaljenosti od glavnih turističnih poti po otoku. Več elementov potrjuje, da je upravljanje z jamo lep primer majhnega vpliva turizma na jamo. Med temi je omejeno število obiskovalcev v skupini, uporaba zgolj lesa za lestve in mostičke za dostop do jamskega vhoda ter uporaba akumulatorskih električnih svetilk (ne da bi bil v jami nameščen stalni sistem osvetljevanja). Zato ima Gran Caverna de Santo Tomàs velike možnosti da postane eno najpomembnejših mest na Karibih, kjer bi lahko na eni strani razvijali ekološki in trajnostni turizem, na drugi pa bi, zaradi svoje velikosti in dolžine, vabila mednarodne in kubanske jamarje ter znanstvenike k stalnim speleološkim in krasoslovnim raziskavam. At Gran Caverna de Santo Tomàs, one of the longest karst system of Cuba, a part of the cave is exploited since 1994 as show cave. It corresponds to the sixth level (out of the total of seven) of the complex karst system, which lowest part is still active today, being the present course of Arroyo Santo Tomàs. Even with the difficulties related to great distance from the main tourist routes of the island, Gran Caverna de Santo Tomàs was visited in the last 10 years by a significant number of tourists and scientists, due to its remarkable variety of karst landscape, at the surface as well as within the cave, and the important archaeological discoveries therein carried out. Management of the show cave is a good example of low-impact effect of tourism in a karst cave, as many features point out. Among these, the limited number of visitors allowed for each group, the choice in using only wooden ladders and passages to reach the cave entrance, and the adoption of rechargeable electrical light (without realizing any fixed light system in the cave). Gran Caverna de Santo Tomàs, therefore, has a high potentiality for becoming one of the best location in the Caribbean to develop an ecological sustainable tourism and, at the same time, due to its size and length, to allow international and Cuban cavers and scientiststo continue carrying out speleological and karst research.
