MAKING THE SPECIAL AND DIFFERENTIAL PROVISIONS OF WTO AGREEMENTS EFFECTIVE FOR THE LEAST DEVELOPED COUNTRIES: PERSPECTIVES FROM BANGLADESH

The paper examines the various aspects of the Special and Differential (S&D) Measures of the WTO and argues that the LDCs can be integrated effectively into the world trading system on a fair and equitable basis through strengthening S&D measures in favour of them. As an active member of the LDCs, Bangladesh is interested in the S&DT and its impact on Bangladesh economy.WTO Agreements, LDCs, Special and Differential Treatment, S&D, Bangladesh

Adult Delinquency and Victimization: A Test of Differential Association Theory with New Data

The theory of differential association applies not only to adolescent people but also to the adult population. A lot of studies tested this theory on delinquent behavior but tests on victimization are rare. Using West Virginia Social Survey 2020 data, this study finds that there is an association between having delinquent friends and learning of self-delinquency in the adult population. It also reports that self-victimization can be predicted with having delinquent friends. The highest probability of victimization is twice for people for having pain medication misuser friends than of people having marijuana user friends. But self-delinquent behaviors do not report to mediate the association between having delinquent friends and victimization for adults as opposed to the adolescent population. Moreover, results indicate that the victimization for having delinquent friends is most predicted for males than females. But the association with peer delinquency and self-delinquency does not vary across gender. As of interest, never-married people compared to married people reported learning marijuana use but not prescription pain medication misuse because of association with delinquent friends

Study of Iron Ion Transit through Three-Fold Channel of Ferritin Cage

Ferritin is an iron-storage globular protein with an ability to uptake, mineralize and release iron ions in a controllable manner. The globular hollow shell allows storage of mineralized iron, with several channels responsible for the transit of ions into the shell and out of it. Understanding of the detailed molecular functioning of ferritin is required for rational design of biomimetic conjugate nano-biosystems containing ferritin-like constituents. In this work, ferritin was investigated both numerically by all-atom molecular dynamics (MD) simulations, and experimentally by Raman spectroscopy. Molecular dynamic simulations of a model system comprising iron ions (Fe2+) and a ferritin trimer expressing a three-fold channel responsible for the ion transport, have revealed a quick entering of ions in the channel. The transit of iron ions through the channel was thoroughly investigated. The transit was found to be driven by both electrostatic charge of ferritin, and interaction between the ions. Exit (expulsion) of an iron ion from the channel was observed at a condition that at least one more ion is present in the channel. Raman characterization of an iron-loaded ferritin solution revealed pronounced bands attributable to iron, as expected. However, Raman spectra of apo-ferritin, which does not contain an iron mineral, also exhibited similar bands. Based on the results of MD simulations, it was hypothesized that apo-ferritin retains iron ions in its three-fold channels, and these ions may produce the observed Raman bands. The study of molecular mechanisms involved in the iron ion transit elucidates the pathways of iron uptake and release in ferritin

Growth and reproductive performance of locally isolated brackish water rotifer (Brachionus plicatilis) feeding different micro algae

Population growth and reproductive capacity of brackishwater rotifer, Brachionus plicatilis, were evaluated, for a period of 8 days in a temperature controlled ( =25°C) microalgallaborarory, under three different algal feeding regimens. The algal species that were tested are: (i) Chlorella sp. (T1), Tetraselmis chui (T2), Nannochloropsis oculata (T 3). The feeding density of each algal species was maintained similar as of 4.5xW6 ceHs mi. The rotifer fed on T. chui showed the highest (p<0.05) population growth (131.5 ind./ml), compared to that fed on Chlorella sp (45.67 ind./ml) and N oculata (43.44 ind./ml). The abundance of egg bearing rotifers was also higher (35.77%) with T. chuithan with Chlorella sp (27.76%) and N oculara (24.60%). The results of the present study indicate that T. chui could be the most suitable algal food for the stock culture of locally isolated rotifer B. plicatilis
