Authors: Deb GK , Mufti MMR , Mostari MP , Huque KS 
Published: November 2013

The BLRI Cattle Breed 1(BCB-1) is a native cattle breed developed by Bangladesh Livestock Research Institute (BLRI) through selective breeding among indigenous cattle of Bangladesh. Data asserted from record sheets of 529 animals maintained during 1992 to 2006 were analyzed to evaluate the reproductive efficiency of BCB-1 cattle in different generations, seasons and parities. The highest percent of animals showed heat during summer season (36.88%) followed by rainy (35.73%) and winter season (27.39%). The highest percent of calving was recorded in summer (43.1%) followed by rainy (31%) and winter (26%). Sex ratio of male: female calves born according to season was the highest in summer (106.31:100) intermediate in rainy (106.06: 100) and lowest in winter (105.00:100). Age at first heat (AFH), age at first calving (AFC), calving interval (CI), service per conception (SPC), gestation length (GL) and post partum heat period (PPHP) of BCB-1 cows were 843.65±17.77, 1225.24±258.92, 451.65±6.51, 1.50±0.83, 283.31±11.50, and 105.51±3.95 days, respectively. AFS and PPHP varied with generation (p<0.01) and that of SPC and PPHP with parity of dams (p<0.05). However, AFC, GL and CI of BCB-1 females did not vary with parity, generation or season of birth. It was concluded that the overall reproductive performances of BCB-1 cattle are within the range of other indigenous cattle of Bangladesh and the at such results of reproductive characteristics may be used for planning cattle breeding strategy of the country.DOI: http://dx.doi.org/10.3329/pa.v19i2.16948 Progress.

Published: November 2013

The present study was undertaken to find out the efficacy of vitamin E and/or vitamin C against mercury (Hg) induced toxicity in mice. Sixty mice were randomly divided into 5 equal groups (n=12). One group of mice (Group A) was kept as control and each of rest four groups (B, C, D and E) were fed with mercuric chloride (HgCl2) in drinking water @ 65 mg/L. In addition to HgCl2 alpha-tocopherol (vitamin E) @ 100 mg/L, ascorbic acid (vitamin C) @ 250 mg/L and combination of vitamin E and vitamin C at same dose were given to the mice of groups C, D and E respectively. All treatments were continued for 28 consecutive days. Four mice of each group were sacrificed on day 1, 14 and 28 and efficacy of vitamin E and vitamin C against Hg induced toxicity were evaluated by observing toxic signs, body weight, hemato-biochemical parameters and postmortem lesions. Mild (++) toxic signs as evident by reduced feed and water intake, salivation, vomiting, excitement, muscle tremor, ataxia, restlessness, incordination and ruffled hair coat were observed from 2nd week (group B) and from 3rd week (group C and D) by intoxication with HgCl2. Significant (P<0.01) reduction of body weight (18.38%) and hematological parameters i.e. TEC (19.88%), TLC (27.89%), Hb content (34.09%) and PCV (9.15%) were observed at day 28 in HgCl2 induced intoxicated mice (group B). At identical period in same group biochemical parameters i.e. AST (46.99%) and ALT (58.72%) increased significantly (p<0.01). Pinpoint hemorrhages throughout the liver and highly (++++) congested kidney was also observed at post mortem (group B). All the parameters i.e. toxic signs, body weight, hemato-biochemical and post mortem lesions were found to be slight (+) or mild (++) and/or improved in rest three groups of mice following treatment with vitamin E, vitamin C and combination of vitamin E and vitamin C. The present study reveals that vitamin E and C have a protective role against Hg poisoning. However, combination of vitamin E and C gave better results.DOI: http://dx.doi.org/10.3329/pa.v19i2.16949 Progress. Agric. 19(2): 93 - 100, 2008

Authors: Nowsad AKM , Islam MR , Shikha FH 
Published: November 2013

A low-cost icebox was developed and its efficacy in icing fish was evaluated in order to minimize huge post-harvest loss and ensure adequate price of wet fish through quality maintenance. Traditional bamboo basket capable of containing 25-30 kg fresh fish was wrapped inside, bottom and top twice by polythene gunny sacs. In between the two layers of gunny sacs, a layer of plant leave mat (hogla mat) and a layer of old nylon net/cloths were placed for insulation. A small plastic pipe (1 cm diameter, 60 cm long) was inserted through the bottom to drain out melted water. The rear end of the pipe was kept fasten with the rim of the basket. To keep the iced fish inside of the wrapped basket, a separate plain polythene sheet was used. Freshly caught Puntius sophore (5.8 ± 0.4 cm) and Cirrhinus mrigala (16.4 ± 1.3 cm) were preserved under adequate icing for 7 to 10 days. Temperature of the iced fish inside was maintained between 0.4o to 3.1oC. Freshness of the fish kept in the new icebox during preservation and transportation was investigated through sensory and biochemical methods. No chance of secondary contamination was found in new ice box because the fish could not come in contact of the basket materials. The device was very easy to clean and keep clean. Shape of filled icebox was found regular and stout with no sign of breakage and leakage. Rate of melting of ice was 23.0 ± 1.6% in 24 hours. Replacement of ice was done at such rate. Melted water was adequately drained out. Iced C. mrigala and P. sophore kept in the icebox were in excellent quality in terms of both sensory and biochemical indicators till the end of 7th or 10th day, respectively. The study suggested that the new icebox was effective in preserving and transporting iced fish.DOI: http://dx.doi.org/10.3329/pa.v19i2.16952 Progress. Agric. 19(2): 119 - 127, 2008

Published: November 2013

The present study was conducted to evaluate the effects of inorganic fertilizers in combination with constant supply of supplementary feeds on growth and production of exotic carps for a period of one year, from February 2007 to January 2008. Three treatments namely T1 {Urea + TSP (2 : 1), 40 kg/ha}, T2 {Urea + TSP (2 : 1), 60 kg/ha} and T3 (Urea + TSP (2 : 1), 80 kg/ha}, each in triplicates were used in the present study. Fertilizers were applied over the ponds fortnightly. The fishes were stocked @ 10,000 fry/ha with a combination ratio of 4 silver carp, 3 common carp and 3 grass carp. A mixture of supplementary feeds composed of rice bran, wheat bran and fish meal (40 : 40 : 20) were provided in all the treatments @ 5% body weight of fish twice daily. The average length (cm) and weight (g) gain were the highest in silver carp (32.3 ± 0.05 cm and 591 ± 1.37g) in treatment T3 and the lowest in grass carp (24.5 ± 0.05 cm and 509.5 ± 0.92 g) in treatment T1 . The highest survival rate (%) was incased for silver carp (81.25%) in treatment T3 and the lowest in grass carp (66.67%) in treatment T1 . The maximum production of all the fishes was recorded in treatment T3 (1920, 1304 and 1164 kg/ha/year respectively), followed by the treatments T2 (1766, 1176 and 1084 kg/ha/year respectively) and T1 (1684, 1108 and 1022 kg/ha/year respectively). The water quality parameters such as temperature (°C), dissolved oxygen (mg/l), pH and transparency (cm), of all the experimental ponds were found within the productive range, which is suitable for fish culture.DOI: http://dx.doi.org/10.3329/pa.v19i2.16953 Progress.

Published: November 2013

The present study was conducted to assess the impact of investment provided under Rural Development Scheme (RDS) of the Islami Bank Bangladesh Limited (IBBL) on the basis of using data collected from 25 respondents of each of group of investors, agriculture and business of the five selected villages in sadar upazila of Mymensingh district. Total household annual incomes were Tk. 59696 and Tk. 87332 respectively for the agriculture group and business group. The beneficiaries have increased their income (61 percent in agriculture sector and 89 percent in business sector) by using RDS credit. After joining the RDS, there was a remarkable improvement in the living standard of the participant households. Thirty one percent of total credit received from RDS was utilized for agricultural purposes, 53 percent for business purposes and 15 percent for family expenditure on an average. Recovery rate of the current credit was 100 percent. None of the respondents of the group was allowed to have new credit until preceding credit was paid back. The findings suggest that the monitoring mechanism should be improved so that clients do not utilize their invested money to any unproductive activities. It is also suggested that adequate size of the investment has to be provided to pursue income generating activities properly.DOI: http://dx.doi.org/10.3329/pa.v19i2.16963 Progress.

To increase production and import substitution of spices, the Ministry of Agriculture has launched the Action Plan by facilitating supply of improved seed, fertilizer along with training for the farmers through institutional linkages of the all-public research and extension agencies from 2002 to 2006. The study was undertaken to evaluate the impact of the Action Plan and to identify the current status of spice crops in relation to production, area, yield, consumption and marketing system in the selected area of spice crops in Bangladesh. An intensive survey of beneficiaries of the five major spices namely onion, garlic, ginger, chili and turmeric from the four region of Bangladesh under Action Plan was done to have necessary information during January to June 2006. Among five major spices, area production, import, demand and net availability of onion occupied higher position compared to others. From the benchmark period (2001-2002) area, production and yield of onion increased from 37 thousand hectare, 150 thousand metric ton and 4 ton/hectare to 141 thousand hectare, 754 thousand metric ton and 5.35 ton/hectare respectively. As a consequence net availability and per capita consumption increased. Area, production, yield, per capita availability and net availability of garlic, ginger, chili and turmeric also increased from the benchmark period to 2005. It was observed that The Action Plan has been successfully generated positive impact on cropping system and socio-economic condition. Estimation of financial profitability shown that ginger appeared to be highly profitable spice crops having net return Tk. 2,82,011 per hectare followed by chili (Tk. 71,441 per hectare), turmeric (Tk. 65,423 per hectare), garlic (Tk. 50,281 per hectare) and onion (Tk. 38,281 per hectare) accordingly.DOI: http://dx.doi.org/10.3329/pa.v19i2.16965 Progress.

Impact of population ageing on real estate markets.
The ageing of the French population is inevitable ; its impact on real estate markets will be significant. The housing demand will turn away from family homes to units tailored to the elderly, more often apartments, in yhe rental sector, and in denser areas. The new demand may well be multifaceted. Such changes will have consequences on the relative prices of various real estate properties. The consequences will be stronger if they are not well anticipated.

Cet article porte sur la position de Thomas Hobbes dans l’histoire philosophique de la réputation. Mon propos sera divisé en trois parties : dans une brève introduction, je situerai la question de la réputation dans le cadre de celle, plus large, de la reconnaissance sociale ; je proposerai ensuite une analyse historique et théorique du « modèle hobbesien », ce modèle révolutionnaire qui a reformulé la question de la réputation dans la pensée moderne sous la forme d’une lutte stratégique pour les signes d’honneur ; j’esquisserai enfin un bref aperçu de la persistance de ce modèle à l’intérieur d’une certaine tradition de la pensée sociale, représentée de manière exemplaire par l’économie des biens symboliques de Pierre Bourdieu.
Réalité marchande et réputation
Authors: Karpik Lucien 
Published: November 2013

Cet article explore le rôle de la réputation dans le choix des produits. Loin de s’insérer dans une trame unitaire, les produits font partie de deux univers distincts : les produits standard et les produits singuliers . Une telle hypothèse implique que les qualifications, les raisonnements et les propositions, loin d’être généraux, sont subdivisés en deux ensembles théoriques. On le démontre par l’examen successif de la réputation des produits, de la réputation des dispositifs de jugement des marchés et des relations entre la confiance et la réputation.
Du lien au like sur Internet

L’article présente deux mesures différentes de la réputation sur Internet : le PageRank de Google, qui mesure l’impact d’une page à travers ses liens, et le Edgerank de Facebook, qui mesure les likes autour d’un contenu, sa circulation sociale et sa redistribution pour en extraire une mesure d’autorité. Ces deux mesures représentent aussi deux façons différentes de concevoir le rapport entre texte et auteur, et le rôle de la construction de l’image sociale de l’auteur dans l’autorité de son message. Ce qui correspond à deux représentations différentes du Web, conçu dans le premier cas comme un espace documentaire et dans le second comme un Web de personnes.

Les enjeux des luttes pour la démocratisation de la communication
Authors: Mattelart Armand 
Published: November 2013

Certains pays latino-américains ont connu ces dernières années des luttes conséquentes pour la démocratisation des moyens de communication, c’est-à-dire contre le « modèle vertical et asymétrique du flux de communication » et pour la multiplication des sources d’expression en dépit des logiques de marché et de contrôle étatique. Armand Mattelart, qui observe l’Amérique latine et ses dynamiques de changement depuis les années 1960, examine ici les acteurs et les situations concrètes qui, bien que non dépourvues de conflits, ont pu conduire, dans certains pays (Uruguay, Argentine, Équateur notamment) à des lois visant une communication plus « populaire, indépendante, incluante », fondée sur un droit à la communication lui-même « indissociable des droits civils et sociaux ».
Liberalism as State Non-Interference
Authors: Karlsson Birgit 
Published: November 2013

Le libéralisme en tant que non-interférence de l’état. Le développement de la législation suédoise des cartels (1911-1953) En Suède, la libre concurrence a été considérée comme très (et de plus en plus) irréaliste durant la première moitié du xx e siècle. Une législation plus stricte en vue de combattre les cartels fut mise en place durant la seconde moitié de ce même siècle. Cette évolution avait été interprétée comme une composante de l’américanisation de même que la libre concurrence peut être considérée comme l’une des valeurs américaines de base. Durant la période 1911-1936, les débats au sein du Parlement suédois se concentraient sur le thème de la production : l’organisation privée de la concurrence, sous la forme de cartels, était considérée comme une voie permettant de diminuer les coûts et, par là, de réduire les prix. Au cours des années 1937-1953, la résistance face à l’intervention étatique s’effaça. Le processus d’urbanisation avait fait entrer la Suède dans la société de consommation de masse et le thème du marché devenait désormais plus au centre des préoccupations de chacun. Les pratiques des cartels relatives à la consommation, de même que le système des prix de gros, étaient désormais plus difficiles à défendre que les cartels de production. JEL Codes: N4, P1, K2, L4
Not Just Cartels
Authors: Berg Bengt Åke 
Published: November 2013

Pas seulement des cartels Dans cet article, le phénomène des cartels se trouve replacé dans une perspective plus large que d’habitude. Le but est de brosser un état de la question en vue de parvenir à une étude des cartels et de la concurrence en Suède avant 1950. Sont considérées ici les multiples formes par lesquelles les firmes interagissent entre elles, dont les cartels ne sont qu’une forme parmi d’autres. Ainsi le comportement de réseau au sein d’un oligopole était important durant la première moitié du xx e siècle. Est étudié ici l’impact des politiques et des pratiques des autres acteurs que les firmes, politiques et pratiques elles-mêmes en interaction. Le gouvernement, les organisations industrielles et les syndicats constituaient aussi des acteurs importants. Leurs activités poussèrent à la mise en place de restrictions de marché au-delà de ce qui avait été prévu. Les activités industrielles des coopératives de consommateurs dans les industries cartellisées ont été perçues dans le discours suédois comme une garantie en faveur d’un marché concurrentiel, mais il est loin d’être clair qu’elles aient pu avoir le moindre impact significatif sur le niveau des prix. Les firmes coopératives furent donc tout à fait profitables et leurs profits financèrent l’expansion d’un groupe industriel qui devint l’un des plus puissants de Suède.

Published: November 2013

Abstract
Dendritic cells (DCs) are heterogeneous cell populations represented by different subtypes, each varying in terms of gene expression patterns and specific functions. Recent studies identified transcription factors essential for the development of different DC subtypes, yet molecular mechanisms for the developmental program and functions remain poorly understood. In this study, we developed and characterized a mouse DC progenitor-like cell line, designated DC9, from Irf8−/− bone marrow cells as a model for DC development and function. Expression of Irf8 in DC9 cells led to plasmacytoid DCs and CD8α+ DC–like cells, with a concomitant increase in plasmacytoid DC– and CD8α+ DC–specific gene transcripts and induction of type I IFNs and IL12p40 following TLR ligand stimulation. Irf8 expression in DC9 cells led to an increase in Id2 and Batf3 transcript levels, transcription factors shown to be important for the development of CD8α+ DCs. We show that, without Irf8, expression of Id2 and Batf3 was not sufficient for directing classical CD8α+ DC development. When coexpressed with Irf8, Batf3 and Id2 had a synergistic effect on classical CD8α+ DC development. We demonstrate that Irf8 is upstream of Batf3 and Id2 in the classical CD8α+ DC developmental program and define the hierarchical relationship of transcription factors important for classical CD8α+ DC development.
Selective Inhibition of KCa3.1 Channels Mediates Adenosine Regulation of the Motility of Human T Cells

Abstract
Adenosine, a purine nucleoside, is present at high concentrations in tumors, where it contributes to the failure of immune cells to eliminate cancer cells. The mechanisms responsible for the immunosuppressive properties of adenosine are not fully understood. We tested the hypothesis that adenosine’s immunosuppressive functions in human T lymphocytes are in part mediated via modulation of ion channels. The activity of T lymphocytes relies on ion channels. KCa3.1 and Kv1.3 channels control cytokine release and, together with TRPM7, regulate T cell motility. Adenosine selectively inhibited KCa3.1, but not Kv1.3 and TRPM7, in activated human T cells. This effect of adenosine was mainly mediated by A2A receptors, as KCa3.1 inhibition was reversed by SCH58261 (selective A2A receptor antagonist), but not by MRS1754 (A2B receptor antagonist), and it was mimicked by the A2A receptor agonist CGS21680. Furthermore, it was mediated by the cAMP/protein kinase A isoform (PKAI) signaling pathway, as adenylyl-cyclase and PKAI inhibition prevented adenosine effect on KCa3.1. The functional implication of the effect of adenosine on KCa3.1 was determined by measuring T cell motility on ICAM-1 surfaces. Adenosine and CGS21680 inhibited T cell migration. Comparable effects were obtained by KCa3.1 blockade with TRAM-34. Furthermore, the effect of adenosine on cell migration was abolished by pre-exposure to TRAM-34. Additionally, adenosine suppresses IL-2 secretion via KCa3.1 inhibition. Our data indicate that adenosine inhibits KCa3.1 in human T cells via A2A receptor and PKAI, thereby resulting in decreased T cell motility and cytokine release. This mechanism is likely to contribute to decreased immune surveillance in solid tumors.
