Citrus assamensis (Family: Rutaceae), commonly known as Satkara, is a pharmacologically diverse medicinal plant. In the present study, the leaf extracts of C. assamensis were subjected to evaluate in vitro anti-diabetic as well as in vivo anti-diarrheal, gastrointestinal motility and acute toxicity activity on Swiss albino mice by using standard protocol. Ethanol and chloroform extracts showed significant inhibitory potentials (**p<0.01) against in vitro α-amylase enzyme at the concentration of 80μg/mL. Significant (*p<0.05, **p<0.01, ***p<0.001) reduction in the number of wet feces and percentage inhibition of diarrheal activity over three hours was observed with all the test doses of the extract compared with the vehicle treated group. Both doses of methanol and ethanol extracts (*p<0.05) and chloroform extract at doses of 100 mg/kg significantly reduced the number of wet feces compared to the control. None of the extracts showed any significant in vivo acute toxicity effect on mice.

Published: February 2019

Five fungicides viz., Autostin 50 WDG, Dithane M 45, Greengel 72 WP, Ridomil Gold MZ 68 WG and Tilt 250 EC exclusively were tested against three pathogenic fungi viz., Colletotrichum gloeosporioides (Penz.) Sacc., Fusarium nivale (Fr.) Ces. and Fusarium sp. associated with Carica papaya L. following poisoned food technique. At 100 ppm Autostin showed complete growth inhibition of C. gloeosporioides, F. nivale and Fusarium sp., while Tilt 250 EC showed complete growth inhibition of C. gloeosporioides at the same concentration. These fungicides at 400 and 500 ppm showed complete growth inhibition of F. nivale. Tilt 250 EC showed complete growth inhibition of Fusarium sp. at 300, 400 and 500 ppm. Eight plants extract, viz., Adhatoda vasica, Azadirachta indica, Curcuma longa, Ocimum sanctum, Lantana camara, Tagetes erecta, Thuja orientalis and Vitex negundo were also tested for their efficacy at 5, 10, 15 and 20% concentrations against these pathogenic fungi. Out of the eight plant extracts, Ocimum sanctum showed highest (88.57%) radial growth inhibition of C. gloeosporioides at 20% concentration. Curcuma longa showed highest (88.55%) radial growth inhibition of F. nivale and Adhatoda vesica showed highest (80.02%) radial growth inhibition of Fusarium sp. at the same concentrations. The present investigation suggests Autostin 50 WDG and Tilt 250 EC as best inhibiting chemical fungicides for C. gloeosporioides, F. nivale and Fusarium sp.

Authors: Makwane Sunil , Srivastava SD , Dua Rajiv , Srivastava SK 
Published: February 2019

A new series of 5-benzylidene-3-(5-ethyl-[1,3,4]thiadiazol-2-yl)-2-phenyl-thiazolidin-4-ones (3a-3m) were synthesized. The reaction of thioglycolic acid with benzylidene-(5-ethyl-[1,3,4] thiadiazol-2-yl)-amine 1a in the presence of anhydrous ZnCl2 afforded the new heterocyclic compounds 5-benzylidene-3-(5-ethyl-[1,3,4] thiadiazole-yl)-2-phenyl-thiazolidin-4-one, 2a. The latter product on treatment with several selected substituted aromatic aldehydes in the presence of sodium ethoxide underwent the Knoevenagel reaction to yield 5-benzylidene-3-(5-ethyl-[1,3,4] thiadiazol-2-yl)-2-phenyl-thiazolidin-4-ones, 3a-3m. The structures of the compounds were confirmed by IR, 1H-NMR, 13C-NMR and mass spectroscopy and by chemical analysis. All the above compounds were screened for their antimicrobial activity against some selected bacteria and fungi such as E. coli, B. Subtilis, and S. Typhi bacteria and A.niger, A. Flavus and F. oxisporium Fungi.

Effect of Dopant Concentrations on Magnetic States of Ti, Mn, And Ni Doped Iii-V Zincblende Compounds
Authors: Shahjahan M , Khan T , Rahman MM 
Published: February 2019

The effect of Ti, Mn, and Ni dopants concentration on various magnetic states of III-V zincblende compounds (Al1-xTx)M is presented by calculation of multiple scattering theory based on Korringa–Kohn–Rostoker coherent potential approximation (KKR-CPA), where T denotes Ti, Mn, and Ni atoms and M represents As and P atoms. The calculations reveal the phase changes in various magnetic states, which are solely controlled by dopant concentrations. The turning points of these behaviors are reported, which are responsible for the change of stable ferromagnetic (FM) state to unstable disordered local moment (DLM) state. The Curie temperature, magnetic moments, and density of states at different concentrations of the dopants are calculated and explain the concurrency with magnetic phase stability.

Published: February 2019

The activity concentrations of natural radionuclides and radiological hazard indices in eleven tea samples collected from local market in Bangladesh have been analyzed by using High Purity Germanium (HPGe) Detector. The average activity concentrations of 226Ra, 232Th and 40K in tea samples have been found to be 21.21±14.04, 32.43±7.48 and 93.47 ± 43.94 Bqkg-1 respectively. The calculated absorbed dose rates due to these radioactive nuclides in tea samples have been found to vary from 26.24 nGyh-1 to 37.95 nGyh-1 and average value was 33.28 nGyh-1. The estimated outdoor annual effective dose rates varied from 38.64 µSvy-1 to 55.89 µSvy-1 with the mean value of 49.02 µSvy-1 which is less than the world average value of 1000 µSvy-1. The values of radium equivalent activity in all samples are less than the permissible maximum value of the radium equivalent activity which is 370 Bqkg-1 according to UNSCEAR 2000 report. The values of external and internal hazard indices for different samples varied from 0.16 to 0.23 with the average value of 0.20 and from 0.21 to 0.29 with an average of 0.26. The value of this index must be less than unity in order to keep the radiation hazard insignificant. It was also found that there is no artificial radionuclide (for example 137Cs) in any of the samples. The data generated in this study will provide baseline radiometric values for natural and artificial radioactivity in tea samples in Bangladesh.

On a Recurrence Relation Related to The Reve’s Puzzle
Authors: Majumdar AAK 
Published: February 2019

The 4-peg Tower of Hanoi problem, commonly known as the Reve’s puzzle, is well-known. Motivated by the optimality equation satisfied by the optimal value function M(n) satisfied in case of the Reve’s puzzle, (Matsuura et al. 2008) posed the following generalized recurrence relation
T(n, a) = min {aT(n-t, a)+S(t,3)}
1≤ t ≤ n
where n ≥ 1 and a ≥ 2 are integers, and S(t, 3) = 2t – 1 is the solution of the 3-peg Tower of Hanoi problem with t discs. Some local-value relationships are satisfied by T(n, a) (Majumdar et al. 2016). This paper studies the properties of T(n+1, a) – T(n, a) more closely for the case when a is an integer not of the form 2i for any integer i ≥ 2.

Authors: Hossain Mohammed Belal , Roy Snigdha , Alam ABM Shafiul 
Published: February 2019

A field experiment was conducted to investigate the effect of foliar application of DAP and TSP on yield and yield attributing characters of lentil. Foliar application of DAP and TSP was performed at flowering and pod formation stages of lentil. Results revealed that maximum fresh weight of plant, nodule number and dry weight of nodule were recorded in F2 treatment at 50% flowering stage of lentil. F1 treatment produced higher branch plant-1 (2.66), pod plant-1(106.47) and seed yield (0.72 t ha-1) of lentil. DAP increased 6% higher grain yield than no foliar application of fertilizer. It may be suggested that foliar application of DAP is a better technology for increasing lentil production in drought prone area of Bangladesh.

Authors: Eva Mahamuda Akther , Shreya Shawda Shafiq , Ahmed Tasnia 
Published: February 2019

Quality of drinking water and juice is very important because if the quality deteriorates by the contamination of faecally originated microorganisms, it may cause serious diarrhea associated problems leading to death. In overpopulated countries like Bangladesh, this is a common scenario to experience diarrheal diseases due to drinking non-potable water as well as contaminated fresh juices. Present study was conducted to determine the quality of drinking water and juice by detection of indicator bacteria Escherichia coli by MPN (Most Probable Number) method which was performed by three consecutive steps including presumptive test, confirmed test and completed test. Other gram negative bacteria were also identified by biochemical methods. The indicator bacterium Escherichia coli was detected in two water samples out of 15 samples and one juice sample out of fifteen samples respectively during the MPN test method. Other Gram negative bacteria found in both water and juice samples included Klebsiella spp., Alcaligenes spp., Pseudomonas spp. and Proteus spp. The quality of drinking water and juice was found to be good in Bangladesh but proper hygiene should be maintained more strictly to avoid the contamination by other gram negative bacteria which are also capable of causing disease.

Authors: Shammi Tahmina , Khalid Md Ismam 
Published: February 2019

Coughing is a physiological process of clarifying the mucosal obstruction through the airways is often be complicated by the invasion following infection by an array of microorganisms. A number of anti-cough formulations are available to combat coughing which is a non-antibiotic drug by nature; however, in some instances these drugs may exhibit anti-microbial trait in action probably due to the chemical properties of the contents. Present study aimed to determine such anti-microbial activity of two commonly used anti-cough mixtures which are locally formulated by the reputed pharmaceuticals in Bangladesh. The antibiotic susceptibility pattern of five laboratory strains of Escherichia coli, Klebsiella sp., Bacillus cereus, Pseudomonas aeruginosa and Staphylococcus aureus were tested by the agar well diffusion method against these two oral liquid samples under investigation used as anti-cough drugs. Sample 1 was found to be highly effective against all of the five test organisms whereas sample 2 was found to be effective against four of the tested organisms. Interestingly, even the lowest amount (50 μl) of both drugs were able to mount inhibitory action against at least two test organisms, the highest amount of both drugs have been found to pose more antimicrobial action than their positive control Gentamycin 10 mg.
