Authors: Ahmed A , Akter N , Hasan S , Ataullah M 
Published: July 2019

The water of different rivers passing in the Sundarban Mangrove Forests (SMF) of Bangladesh was analyzed to know the spatio-temporal variations in the water quality and phytoplankton diversity of the river. The pH of the waters of all the rivers examined showed a narrow range of variation (6.60-7.8 in 2015 and 6.3 to 7.5 in 2016) indicating the buffering capacity of different rivers. The values of pH showed a slightly decreasing tendency indicating the acidification of river waters which might be due to increase of global CO2 concentration in the atmosphere. The temperature of water, conductivity, salinity, DO (ppm), DO (% sat), K, Na, was found to vary from 27.6 to 30.8° C, 8.00 to 32.30 mS/cm, 5.50 to 23.00 ‰, 3.5 to 6.35 ppm, 46.60 to 82.00 %, 125.00 to 630.00 mg/l, 600 to 4300 ppm, respectively in April 2015; and ranged from 28.8 to 31.0° C, 9.48 to 31.60 mS/cm 5.00 to 24.00 ‰, 0.11 to 5.33 ppm, 1.2 to 95.2 % saturation, 110 to 670 ppm, 4683.5 to 13465.10 ppm, respectively in March 2016. The values of Ca, Mg and Fe were 210 to 500 ppm, 320.0 mg/l to 892.0 mg/l and 0.25 to 0.050 mg/l, respectively in 2015. The amount of DO was very low during 2016 especially in the locations 1, 2, 3 which might be due to cloudy condition during sampling time. Principal component analyses (PCA) of different variables of the year 2015 showed that PC-1 had positive loading of water temperature, air temperature, humidity, pH, conductivity, Salinity, Na, K, Fe, Mg, Zn whereas PC-1 of different variables during 2016 showed positive loading of only water temperature and pH. Maximum number of phytoplankton taxa was recorded from Sela river (Tambulbunia) where 34 taxa (with the unknown ones) were recorded followed by Passur river (near Mongla Ferry Ghat). Coscinodiscus is found to be the dominant genus. Maximum Shannon-Weaver index of diversity was found in Homra Khal (value was 6.825) and minimum was found in Sela river (where the oil tanker sank and value was 0.0). Only one species of phytoplankton was found in this place. Maximum species richness (d) was observed in Passur river at Mongla ferry ghat with a value of 14.81 whereas, maximum evenness (e) was found in location 16 (Homra khal with a value of 5.437).

Some behavioural aspects on the Hemidactylus species of Bangladesh
Authors: Rabbe MF , Jaman MF , Rahman MM , Alam MM 
Published: July 2019

Hemidactylus is a taxonomically complex genus and little is known about its feeding and breeding behavior in Bangladesh. Most of the species of this genus have a preference to live within human habitations, and play an important role in ecosystem, controlling insect pest population. Their breeding strategy is almost similar with each other and associated with their body structure. Review of literature found that there is a relationship between life history pattern and their reproductive biology. They lay two eggs per clutch usually and the highest egg number (12) has been recorded for H. frenatus. Strong significant positive correlation (r = 0.91) was found for preclaocal-femoral pores and egg number. Besides, significant negative correlation was found for average female body size and egg number (r = 0.96). Previous work and observation records showed that feeding habit is almost similar among all species of Hemidactylus and dipteran insects were the mostly consumed food item.

Published: July 2019

A pot experiment was conducted to evaluate the effect of Eggshell and Lime in ameliorating lead uptake to alleviate toxicity of lead in Kalmi (Ipomoea aquatica).The lengths, fresh and dry weights of shoot was decreased significantly in 200 mg Pb kg-1soil as compared to the control. The similar significant decreasing trend in macro nutrient concentration in shoot and root was also observed. The percentage of N, P, K, S, Mg and Ca concentrations in edible parts (shoots) decreased by 7.73, 54.55, 12.50, 35.29, 17.65 and 19.61, respectively in 200 mg Pb kg-1 treated pots compared to the control. On the other hand, Pb concentration in shoot and root was the highest at 200 mg Pb kg-1 treated pots (36.14 and 111.14 mg Pb kg-1) and the lowest was in the control treatment (3.48 and 14.48 mg Pb kg-1 pot-1). Treatments of lime and eggshell had positive effects on the productivity of Kalmi and remediating the effect of lead uptake by the plants. Between the two amendments eggshell showed better efficiency in ameliorating the toxic effects of lead and increasing the macro nutrients uptake by plants. Lime and eggshell ameliorated Pb uptake of kalmi in shoot (edible parts) by 32.26 and 61.79% compared with the control and reduced root to shoot transfer (TrF) of Pb by15.15 and 30.30% in shoots and roots of kalmi compared to the untreated pots.

Ecological and social impacts of eucalyptus tree plantation on the environment
Authors: Bayle GK 
Published: July 2019

Eucalyptus is an ever green flowering tree and a shrub which belong to the family Myrtaceae, subfamily Myrotideae and consists of some 800 species. This tree is native to Australia and widely planted for various uses in the different parts of Ethiopia integrating into the various farming systems, and their planting has resulted in high economic profitability. It is over a century since eucalyptus was introduced in Ethiopia for multipurpose use and rescues the remaining indigenous forests from being destroyed, for controlling soil erosion, for replacing indigenous species for fuel-wood, thereby preventing further degradation of natural forests by quickly producing firewood, would eliminate the causes which frequently may have led to land degradation and desertification and also a food and habitat for wild animals. But, it also a harmful effect on the environment, uses a lot of nutrient which is leading to soil exhaustion and reduction of crop yields, secretion of allelochemical and decreasing crop production, but the trees are neither good nor bad, and careful analysis of the ecological and social implications should be undertaken before planting. Decisions, such as what, where, why and how to grow and how to manage it have to be made; and the social and ecological implications of each decision, as well as the economic implications, have to be weighted up.

Published: July 2019

Multiple choice question (MCQ) test is the most popular assessment tool that used in medical schools, faculty training on construction of multiple choice questions and peer review are the main factors that contributing to have a good quality MCQ test. This study aimed to evaluate the effect of these two factors on the quality of MCQ test. An extensive training program was conducted for the staff members who were participated in teaching and assessment of undergraduate medical students of clinical biochemistry and psychiatric courses. Post-test item analysis was used to compare pre-training with post-training item analysis parameters. Chi-square test was applied, level of significance was 5%. Regarding difficulty index, it showed great improvement in number of questions which lie in acceptable range of difficulty from 16%, 25% before the training program to 61%,42% after the training program for psychiatry and clinical biochemistry courses respectively and this is significantly different (P0.05). In psychiatry course the number of questions with negatively discrimination power had been decreased from 36% before training program to 10% after it (P value 0.05). No significant improvement noticed in biochemistry course regarding this aspect. Both courses were showed improvement in the function of distracters, the percentage of test items where all distracters were functioning was increased from 11% to 41% in psychiatry course (P value=0.0002), and from 12% to 46%, in biochemistry course (P value=0.0001). The two courses which included in the study showed increased reliability after the training program and peer review processes, but this improvement is not statistically significant. A dramatic improvement was observed in the quality of MCQs after peer review and training program. We recommend adopting training program on construction of MCQs to be as teaching license for all medical school staff members in Saudi Arabia.

”DRA ÅT SKOGEN”

Published: July 2019

Kan rurala miljöer, naturen och skogen, vara produktiva platser för queers och queerteori, i stället för att uppfattas och utmålas som hotfulla, moralkonservativa och bakåtsträvande sådana? I poeten Eva-Stina Byggmästars (f. 1967) naturdikt försätts den föreställda motsättningen mellan stad och land i gungning. I den här artikeln vill jag, med stöd av forskning som utforskat sambandet mellan natur, ruralitet och queera perspektiv, undersöka hur Byggmästar skapar skogen och det lantliga som miljö och idyll, men även som motstånd. Genom att skapa en naiv och lustfylld grön poetisk idyll lockar hon fram en mer svårfångad politisk idyll och ställer på så sätt frågan om skogen och landsbygden faktiskt kan vara ett paradis för queers i verkligheten, liksom i dikten. Naturen i form av både domesticerad trädgård och vild skog är nämligen, i Byggmästars dikter, inte en farlig plats där normer om sexuell och könsmässig ”naturlighet” hårdbevakas och verkställs, utan snarare en frizon för lust, omsorg och sensuell nyfikenhet. Snarare uppmuntrar den förment konservativa naturen till ett överflöd av queer kärlek. Jag vill mena att Byggmästars dikt formulerar en särskild naturqueer estetik, vilket skapar en möjlighet inte bara att diskutera vari denna estetik består och hur den pekar mot en queer framtid på landsbygden, utan också ett tillfälle att utforska föreställda motsättningar mellan queerteori och ekokritik – motsättningar som jag finner att Byggmästar överbryggar i sin dikt.

I handen håller jag en rektangulär häftad och grå smårutig skrivbok med rödfärgade kanter. Boken har tillhört min gammelmormor Ingeborg Göransson. Hon föddes i en jordbrukarfamilj i Offerdals socken i Jämtland 1893. Det är under hennes tid som seminarist i Östersund under åren 1912 till 1914 och sedermera lärarinna i byn Enarsvedjan i Offerdal från 1914 till 1918, som anteckningarna i boken är skrivna. I denna artikel gör jag en queerläsning såväl av Ingeborgs egna anteckningar som av berättelser om hennes liv utifrån muntliga utsagor. Min läsning av Ingeborgs texter innebär en dubbel analytisk akt: att samtidigt både ifrågasätta heteronormativitet som tolkningsram för livshistorier oavsett tid och rum och problematisera det som i vår tid blivit till normativa föreställningar om hur och var queera liv kan levas.

Published: August 2019

The administration of cephalosporin group antibiotics in patients with post-surgical appendicitis is necessary to prevent postoperative wounds. This pharmacoeoconomic study was conducted retrospectively in the period of 1 January to 31 December 2015 in RSUD Subang for the purpose of determining the effectiveness of drugs and the cost of antibiotic use of ceftriaxone, cefotaxime, and ceftizoxime injection by Cost Effectiveness Analysis method. The subject of the patient was 78 people. Based on Average Cost Effectiveness Ratio (ACER), the smallest value is ceftriaxone Rp 729.124 / day, while the result of Cost Effectiveness plane with cefotaxime as standard drug, ceftriaxone occupies quadrant IV and ceftizoxime occupies quadrant I. The result of Incremental Cost Effectiveness Ratio (ICER) calculation obtained by difference of value equal to Rp 106.347 / day hence can be concluded that antibiotic injection of cefotaxime as standard injection antibiotics used by RSUD Subang can be replaced by antibiotic injection of ceftizoxim by adding cost Rp 106.347 / day but need attention to resource especially funds owned and should be selected if sufficient resources are available.

Aceh Province as an area with special authority for the implementation of Islamic law, gives the authority to distribute zakat through non-structural institutions Baitul Mal Based on Qanun Number 10 of 2007. The right distribution of productive zakat is one of the targets of achievement in reducing poverty in urban areas. For this reason, the distribution of productive zakat needs to be examined in a specific study in an effort to reduce poverty in the city of Banda Aceh. This study uses multiple regression methodology by placing productive amil zakat performance as a moderating variable. which reduces poverty. Sampling was carried out as many as 100 people mustahik productive zakat in the micro business group in 2017. Based on the results of the study found that the amount of productive zakat, income, and performance of amil significantly influence the decrease of the poverty level of mustahik zakat in the city of Banda Aceh. The decline in poverty which is indicated by the income gap ratio, is able to decrease with the range of the percentage spread of 0.19% - 0.25%. So it can be concluded that the distribution of productive zakat can reduce the level of inequality in productive zakat income. Keywords: Zakat, Poverty, Gap
