Authors: Lipták Imrich 
Published: October 2013

Abstract The paper presents current trends in determining the dynamic deformations of bridge structures through the exploitation of geodetic measurements by accelerometers. The main aim of the paper is to demonstrate the practical application of these measurements on the cycling bridge over the river Morava in Devínska Nová Ves. Possibilities for the processing and analysis of accelerometer measurements by spectral analysis are described. An evaluation of the results is realized based on the modal characteristics from a numerical model designed by the finite element method.

Brucellosis is an important zoonoses causing signififant economic loss but is very often neglected in Bangladesh. Therefore, a survey was undertaken to investigate the seroprevalence of brucellosis in sheep of selected areas (Gaibandha sadar and Gobindagonj upazilas) in the Gaibandha districts of Bangladesh. A total of 206 sera samples were collected from sheep and were tested for presence of Brucella specific antibody by Rose Bengal Plate Test (RBPT) as screening test and the RBPT positive samples were further confirmed using indirect Enzyme-linked immunosorbent assay (i-ELISA). Information of sheep's age, sex, housing system, pregnancy status, abortion and reproductive disorder were collected using questionnaire. The overall seroprevalence of brucellosis in sheep was recorded as 3.39% in RBPT and 2.91% in i-ELISA. The prevalence of brucellosis in female sheep (3.41%) was higher than male (3.33%). The prevalence of brucellosis in sheep with abortion history was higher (4.34%) than the sheep with no abortion (3.08%). The highest prevalence of brucellosis (4.00%) was found in sheep keeping with others species such as cattle and goat compared to the sheep keeping alone (1.79%). The higher rate (4.59%) of Brucella antibody was recorded in sheep of 1-2 years of age. Brucellosis might be an important hinders for sheep production in Bangladesh. The present study will help to develop an appropriate prevention strategy for brucellosis in Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16562Progress. Agric. 23(1 & 2): 25  32, 2012

Authors: Zaman T , Alam MMM 
Published: October 2013

The experiment was conducted in two cement made cisterns for a four-week period. Important physico-chemical water quality parameters and harvesting time in periphyton production were studied. During the study period, four groups of phytoplankton and two groups of zooplankton were observed. Among phytoplankton, Chlorophyceae was the most dominant having 62% Chlorella followed by Bacillariophyceae having 15% Navicula and 12% Cyclotella, Cyanophyceae having 5% Oscillatoria and 2% Anabaena and Euglenophyceae having 2% Euglena and 1% Phacus. The grand averages of periphyton mass production were 0.569 (± 0.242) mg DM/cm2 in C-1. There was highly significant (p<0.05) variation (F = 14.692) between C-1 and C-2 in respect of periphyton production. Cistern-1 was identified as more productive due to its favourable water quality parameters, i.e., water temperature of 24.6 to 28.3 ºC, Secchi disc reading of 18 to 33 cm, dissolved oxygen of 4.67 to 9.55 mg/L, pH of 9.12 to 10.18, NO3-N of 3.58 to 10.90 mg/L, NH3-N of 0.26 to 0.40 mg/L, PO4-P of 7.5 to 3.4 mg/L, conductivity 0.412 to 0.719 Ms. Third addition of substrate, that means 18- 19th day was identified as the optimum harvesting time of periphyton production.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16565Progress.

Published: October 2013

This study aimed to determine the cost, return, and profitability of broiler production in some selected areas of Mymensingh district. It was mainly based on primary data which were collected through face to face interview from the respondents of broiler production during the month of December, 2011. Selected samples consisted of 30 broiler farm owners selected by using purposive sampling technique. For the analysis of data, tabular and production function techniques were used. This study estimated the average cost of raising broiler to be Tk. 8,35,910.65 per farm per year. It was found that the variable cost per farm per year stood at Tk. 8,23,735.93 which accounted for 98.54 percent of total cost. The total fixed cost per farm per year accounted to Tk. 14,041.66. It is evident from the study that the gross return per farm per year stood at Tk. 10,78,022.39. The net return per farm per year was calculated at Tk. 2,42,111.47. The findings revealed that broiler production was a profitable enterprise. Cobb-Douglas production function was also applied to explore the specific effect of the factors on broiler production. It was observed that most of the included variables had significant impact on broiler production. Out of six variables included in the regression, four variables (i.e., feed cost, cost of day-old chick, labour cost and litter cost) had significant positive impact on return. This study also identified some problems in the production of broiler in the study area. Finally, based on the findings of the study, some recommendations were made for the development of broiler production in Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16568Progress.

Authors: Khan MA , Huda FA 
Published: October 2013

Bangladesh Fisheries Research Institute (BFRI) has developed an improved namely, strain silver barb which shows superior performance in terms of growth and production in on-station condition. This paper analyses the comparative performance of improved silver barb strain on an average as well as on an efficient farm. Ordinary least squares regression and tobit models are estimated on an average weight at harvest and the survival rate, respectively to assess the comparative performance of the improved silver barb strain on an average farm. Stochastic frontier functions for weight at harvest are also estimated to assess the comparative performance of the improved strain on an efficient farm. The result shows a superior performance of the genetically improved silver barb strain compared to traditional strain on both average and efficient farms. On an average farm, the improved silver barb strain gives 25% higher body weight at harvest. The breakeven price above variable cost is 4.71% lower for the improved strain. The result shows that the improved silver barb strain has higher potential yield and average yield than the traditional strain.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16577Progress.

Authors: Uddin MT , Farjana I 
Published: October 2013

The study was designed to examine the low lying inland fish farming practices of Karimganj upazila under Kishoreganj districts. Field level data were collected through direct interview using semi-structured questionnaire. Eighty sample farmers were selected purposively from the study areas. Six types of farming practices were identified in the study area among which only two types were prominent i.e., pond fish farming and Beel fish farming. Tabular, statistical and mathematical analyses were done to achieve the major objectives. The benefit cost ratio in Beel fish farming was 2.86 and in case of pond fish farming it was 1.95. Multiple regression model was used to explain the variation of gross return of pond and Beel fish farming and it was found that coefficients of human labour, feed, cowdung and manure had significant impact on gross return, whereas coefficients of feed, harvesting and making sanctuary had significant impact on gross return of Beel fish farming. Resource use efficiency was calculated by the ratio of marginal value product and marginal factor cost. Finally, the study identified some important problems of low lying inland fish farming and suggested probable solutions relating to the problems.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16619Progress.

Factors Responsible for Yield Gap of Wheat at Farmers Field in Two Districts of Bangladesh
Authors: Kashem MA , Miah MAM , Islam MA , Roy PC 
Published: October 2013

The main purpose of the research was to identify factors responsible for yield gap in wheat production. Eighteen (18) experiments were conducted in two major wheat growing districts Rangpur and Dinajpur in two consecutive years. The selected varieties for the conducted research were Prodip, Satabdi and Sourav. All the experiments were established in farmers fields providing all recommendations for wheat production. It was observed that yield gap varied with the variety and farmers to farmers and location to location. The overall yield gap of Prodip was the highest (18.43 percent) followed by Sourav (18.15 percent) and Satabdi (17.45 percent). Yield gaps of all the wheat varieties under study were higher in Rangpur site than Dinajpur site. The practice gap was the highest in gypsum application (69 percent) followed by boron (67 percent), sowing time (40 percent). Practice gaps in the application of MoP, TSP and irrigation were almost equal, 40 percent, 37 percent, and 36 percent respectively. Late sowing, non use of dolomite and micro nutrients (zinc and boron) in wheat yield with sub-optimal doses of phosphatic and potash fertilizers were the main reasons for yield gap. Adoption of short duration T. aman variety and optimal doses of chemical fertilizers with micro nutrients in wheat field could minimize this gap to a greater extent. Preventive measures against bird attack after sowing of seeds for optimum plant population would have impact in narrow down this yield gap as well.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16620Progress.

Published: October 2013

•Premise of the study:To understand the early evolution of mycorrhizal symbioses, it is important to know the fungal partners of gametophytes and sporophytes for basal lineages of vascular plants. Subterranean mycotrophic gametophytes of the clubmossDiphasiastrum alpinumfound at three localities gave an opportunity to study their morphology and anatomy and to identify and describe their hitherto unknown fungal endophytes. In addition, sporophytes were screened for fungal partners.•Methods:Gametophytes with attached young sporophytes were excavated, and their anatomy and their associated fungi were studied by light microscopy. DNA was isolated and amplified with both universal and group‐specific fungal primers for the ITS region, the large subunit and small subunit of the nuclear rDNA, respectively, to identify the fungal partner.•Key results:Gametophytes were uniformly colonized by a fungus with septate hyphae forming coils and vesicles. Its morphology resembles that of the sebacinoid genusPiriformospora. Both ITS and LSU sequences were identified as Sebacinales group B, a basal clade of the Agaricomycetes (Basidiomycota). This fungus was detected in 11 gametophytes from two localities and in rootlets of adjacentCalluna vulgaris(Ericaceae) plants, but was absent in roots of sporophytes. In addition, several ascomycetes and glomeromycetes were found by DNA sequencing.•Conclusions:Our study suggests a fungus belonging to Sebacinales group B as the main fungal host of theD. alpinumgametophytes. However, Sebacinales group B fungi occur as well in adjacent Ericaceae plants; therefore, we assume the mycoheterotrophic gametophyte to be epiparasitic on Ericaceae, which would explain the steady association of these plants.
La Grande-Bretagne et l'Irlande dans la Première Guerre mondiale
Authors: Pennell Catriona , Poncharal Bruno 
Published: October 2013

À la veille de la Première Guerre mondiale, l’Irlande semblait au bord de la guerre civile. Pourtant, le déclenchement des hostilités permit paradoxalement un apaisement des relations entre la Grande-Bretagne et l’Irlande. Cet article analyse cette détente anglo-irlandaise à travers le prisme des engagements volontaires et s’intéresse à trois moments en particulier : 1914, 1916 et 1918. Il démontre que la contribution irlandaise à l’effort de guerre fut volontaire et procéda d’une automobilisation, même lors de la Pâques 1916 et des débats suscités par l’instauration potentielle de la conscription au printemps 1918. Cet article souligne ainsi l’importance du caractère pluraliste et pragmatique du libéralisme britannique.

Abstract
Chronic debilitating pruritus is a cardinal feature of atopic dermatitis (AD). Little is known about the underlying mechanisms. Antihistamines lack efficacy in treating itch in AD, suggesting the existence of histamine-independent itch pathways in AD. Transient receptor potential ankyrin 1 (TRPA1) is essential in the signaling pathways that promote histamine-independent itch. In this study, we tested the hypothesis that TRPA1-dependent neural pathways play a key role in chronic itch in AD using an IL-13–transgenic mouse model of AD. In these mice, IL-13 causes chronic AD characterized by intensive chronic itch associated with markedly enhanced growth of dermal neuropeptide-secreting afferent nerve fibers and enhanced expression of TRPA1 in dermal sensory nerve fibers, their dorsal root ganglia, and mast cells. Inhibition of TRPA1 with a specific antagonist in these mice selectively attenuated itch-evoked scratching. Genetic deletion of mast cells in these mice led to significantly diminished itch-scratching behaviors and reduced TRPA1 expression in dermal neuropeptide containing afferents in the AD skin. Interestingly, IL-13 strongly stimulates TRPA1 expression, which is functional in calcium mobilization in mast cells. In accordance with these observations in the AD mice, TRPA1 expression was highly enhanced in the dermal afferent nerves, mast cells, and the epidermis in the lesional skin biopsies from patients with AD, but not in the skin from healthy subjects. These studies demonstrate a novel neural mechanism underlying chronic itch in AD and highlight the complex interactions among TRPA1+ dermal afferent nerves and TRPA1+ mast cells in a Th2-dominated inflammatory environment.

Abstract
The “liver tolerance effect” has been attributed to a unique potential of liver-resident nonprofessional APCs including hepatocytes (HCs) to suppress T cell responses. The exact molecular mechanism of T cell suppression by liver APCs is still largely unknown. In mice, IL-10–dependent T cell suppression is observed after Th1-mediated hepatitis induced by Con A. In this study, we show that HCs, particularly those from regenerating livers of Con A–pretreated mice, induced a regulatory phenotype in naive CD4+ T cells in vitro. Using reporter mice, we observed that these T regulatory cells released substantial amounts of IL-10, produced IFN-γ, failed to express Foxp3, but suppressed proliferation of responder T cells upon restimulation with anti-CD3 mAb. Hence, these regulatory cells feature a similar phenotype as the recently described IL-10–producing Th1 cells, which are generated upon activation of Notch signaling. Indeed, inhibition of γ-secretase and a disintegrin and metalloproteinase 17 but not a disintegrin and metalloproteinase 10, respectively, which blocked Notch activation, prevented IL-10 secretion. HCs from Con A–pretreated mice showed enhanced expression of the Notch ligand Jagged1 and significantly increased receptor density of Notch1 on CD4+ T cells. However, HCs from Con A–pretreated IFN regulatory factor 1−/− mice, which cannot respond to IFN-γ, as well as those from IFN-γ−/− mice failed to augment IL-10 production by CD4+ T cells. In conclusion, it seems that HCs fine-tune liver inflammation by upregulation of Jagged1 and activation of Notch signaling in Th1 cells. This mechanism might be of particular importance in the regenerating liver subsequent to Th1-mediated hepatitis.
Adrenergic Regulation of IgE Involves Modulation of CD23 and ADAM10 Expression on Exosomes

Published: October 2013

Abstract
Soluble CD23 plays a role in the positive regulation of an IgE response. Engagement of the β2 adrenergic receptor (β2AR) on a B cell is known to enhance the level of both soluble CD23 and IgE, although the mechanism by which this occurs is not completely understood. In this study, we report that, in comparison with a CD40 ligand/IL-4–primed murine B cell alone, β2AR engagement on a primed B cell increased gene expression of a disintegrin and metalloproteinase (ADAM)10, which is the primary sheddase of CD23, as well as protein expression of both CD23 and ADAM10, in a protein kinase A– and p38 MAPK–dependent manner, and promoted the localization of these proteins to exosomes as early as 2 d after priming, as determined by both Western blot and flow cytometry and confirmed by electron microscopy. In comparison with isolated exosomes released from primed B cells alone, the transfer of exosomes released from β2AR agonist–exposed primed B cells to cultures of recipient primed B cells resulted in an increase in the level of IgE produced per cell, without affecting the number of cells producing IgE, as determined by ELISPOT. These effects still occurred when a β2AR antagonist was added along with the transfer to block residual agonist, and they failed to occur when exosomes were isolated from β2AR-deficient B cells. These findings suggest that the mechanism responsible for mediating the β2AR-induced increase in IgE involves a shuttling of the β2AR-induced increase in CD23 and ADAM10 proteins to exosomes that subsequently mediate an increase in IgE.
