Rigorous Coupling of Geomechanics and Multiphase Flow with Strong Capillarity
Authors: Kim J.. , Tchelepi H.A.. A. , Juanes R.. 
Published: November 2013

SummaryWe study sequential formulations for coupled multiphase flow and reservoir geomechanics. First, we identify the proper definition of effective stress in multiphase-fluid systems. Although the average pore-pressure p¯ —defined as the sum of the product of saturation and pressure of all the fluid phases that occupy the pore space—is commonly used to describe multiphase-fluid flow in deformable porous media, it can be shown that the "equivalent" pore pressure pE —defined as p¯ minus the interfacial energy—is the appropriate quantity (Coussy 2004). We show, by means of a fully implicit analysis of the system, that only the equivalent pore pressure pE leads to a continuum problem that is thermodynamically stable (thus, numerical discretizations on the basis of the average pore pressure p¯ cannot render unconditionally stable and convergent schemes). We then study the convergence and stability properties of sequential-implicit coupling strategies. We show that the stability and convergence properties of sequential-implicit coupling strategies for single-phase flow carry over for multiphase systems if the equivalent pore pressure pE is used. Specifically, the undrained and fixed-stress schemes are unconditionally stable, and the fixed-stress split is superior to the undrained approach in terms of convergence rate. The findings from stability theory are verified by use of nonlinear simulations of two-phase flow in deformable reservoirs.

Published: November 2013

AbstractMaternal responsiveness of sows affects piglet survival rate by influencing the economic results of breeding. The purpose of this article was to present the relations among housing environment for sows during periparturient period and lactation, endocrine changes in sows, and maternal behaviour and welfare, which ultimately all affect the productive results. The following welfare-related factors were discussed in this paper: the type of farrowing environment, including the type of pen, the area for free movement or confinement crates, alternative loose-housing systems, the importance of nest building for further nursing, and fear as a factor which can impair productivity.

Abstract The objective of the study was to identify single nucleotide polymorphism (SNP) genetic markers in the equine TERT gene sequence, which were used to assess the degree of differentiation between Anglo-Arabian and Hucul horses. Polymorphisms were identified by sequencing 30 amplification products representing 18000 bp of TERT sequences. Twenty-seven SNP markers were investigated, which were at genetic equilibrium. Haplotypes and genotypes were determined, and usefulness of polymorphisms for genetic studies was assessed based on minor allele frequency (MAF). Alleles characteristic of both horse breeds were identified. SNP markers with MAF > 0.18 were considered suitable for genetic analyses concerning association studies and parentage testing. In total 26 haplotypes were identified, of which three were common to the investigated horse populations. Twelve haplotypes were found only in Anglo-Arabians and 11 in Hucul horses. Identified polymorphism of TERT gene might be useful in the search for genetic basis of aging in the Equus caballus species.
Human CD46, CD55 and CD59 expression influence on swine transgenic fetal fibroblasts’ survivability in the presence of human complement components

Published: November 2013

AbstractMechanisms regulating the activity of the complement system responsible for the rejection of transplant organs are balanced so that the attack is instantaneous but is restricted to the infected cells of the organism. The most important components regulating its activity comprise CD55 and CD46 factors as well as the CD59 anchored in the cell membrane. Hyperacute response of the immunological system appears to be the key in the xenotransplant rejection and the elaboration of methods preventing its occurrence will give a real chance for the development of xenotransplantation. Gene constructs containing coding sequences of human CD46, CD55 and CD59 were prepared and used to transfect porcine fetal fibroblasts. Stable lines were molecularly characterized for an integration of transgenes by PCR. Lines with a stable integration of transgenes were subjected to further characterization of expression by RT-PCR and vitality test. Molecular characteristics of the transgenic cell lines obtained revealed a steadfast integration and, in the majority of cases, expression of the introduced transgenes. The performed cytotoxicity analysis demonstrated that transgenic lines were characterised by a higher survivability rate than non-transgenic cells in the presence of human serum which proved their protective influence in relation to the activity of the complement system.

Published: November 2013

AbstractThe research aimed at establishing the pattern of air movement inside a 2×10 herringbone milking parlour equipped with supply mechanical ventilation. Observations and analyses were made for the streams of air supplied to the parlour, their movement pattern and spread range. Also, temperature and relative air humidity after and before evening milking routine were measured. It has been concluded that barriers installed inside the milking parlour play a significant role in creating unfavourable microclimatic conditions during milking, particularly for the last group of cows. The study points out possible threats to animal welfare and operator’s working conditions. Based on the conducted experiments, the paper defines recommendations for proper design of ventilation systems inside herringbone milking parlours.

Published: November 2013

AbstractThe aim of the present study was to define at what time point animal is dying and how quickly changes in the function of brain and heart can be observed. Four groups of sedated standard dark male mink (Mustela vison) were tested: euthanasia with filtered exhaust gases (CO concentration in the killing box 4%, 8 animals), carbon dioxide (CO2 from a cylinder, concentration in the killing box 80%, 8 animals), carbon monoxide (CO from a cylinder, concentration in the killing box 4%, 9 animals) and euthanasia with carbon monoxide (CO from a cylinder, concentration in the killing box 2%, 6 animals). Brainstem auditory evoked responses (BAER), electroencephalography (EEG), electrocardiography (ECG) and respiratory rate were measured before and during euthanasia. Mean time of decline/absent BAER was 112/176, 138/183, 235/390 and 528/833 seconds after gas application in groups, respectively. Mean time for first changes/absence of EEG was 42/86, 39/75, 55/190 and 176/426 seconds after gas application in groups, respectively. Mean time for first changes in respiration/absent breathing was 42/217, 28/227, 144/477 and 331/901 seconds after gas application in groups, respectively. Mean time for first changes/absence of ECG was 105/292, 117/220, 215/289 and 481/682 seconds after gas application in groups, respectively. Our results indicate that the studied gases first affect brain and brainstem which was seen as loss of EEG and BAER and just thereafter respiration and heart rate in turn. While sensitivity to pain is essentially related to consciousness and function of brain, gases can be considered to primarily and effectively lead to state of non-pain. Particularly the death with the filtered exhaust CO and the cylinder CO2 gases occurs quickly and in very comparable times. The euthanasia with the cylinder CO of 2% concentration seems to be too long and is most likely not suitable for the mink euthanasia in general. Observable signs of marked irritation or aversion were not found during exposure to studied CO and CO2 gases.

Published: November 2013

Genetic diversity in 38 traditional local rice genotypes grown as Jhum in the hilly areas was studied under rainfed condition through Mahalanobis D2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the clusters. The intra-cluster distances were lower in all the cases reflecting homogeneity of the genotypes within the clusters. The cluster V contained the highest number of genotypes (12) and the cluster I and III contained the lowest (5). The highest intra-cluster distance was noticed for the cluster III and lowest for cluster I. The highest inter-cluster distance was observed between cluster I and III followed by cluster II and III, cluster III and IV and the lowest between cluster II and IV. Regarding inter-cluster distance, the genotypes of cluster III showed high genetic distance from all other clusters. The genotypes from cluster III could be hybridized with the genotypes of other clusters for producing transgressive segregants. Based on positive value of vector 1 and vector 2, flag leaf length, flag leaf width, days to 50% flowering, days to maturity, unfilled grain panicle-1, grain length and grain length breath ratio had maximum contribution towards genetic divergence. The highest cluster means for plant height, filled grains panicle-1 and yield were obtained from cluster III. The highest flag leaf width, days to 50% flowering, unfilled grain panicle-1, grain length, grain breath and grain length breath ratio while the lowest mean value for yield were found in cluster I. The lowest days to 50% flowering and maturity, and highest mean value for 1000-grain weight were found in cluster IV. Therefore, more emphasis should be given on cluster I and cluster III for selecting genotypes as parents for crossing with the genotypes of cluster IV which could produce new recombinants with desired traits.DOI: http://dx.doi.org/10.3329/bjpbg.v24i2.17003

Published: November 2013

To regenerate plantlets both directly and indirectly, different explants (cotyledon, hypocotyls, root tip and shoot tip) of mungbean were cultured on medium supplemented with different concentrations and combinations of BAP (0, 1.0 and 5.0 mgL-1) and NAA (0, 0.5 and 2.5 mgL-1)). Cotyledon explants performed best in callus induction (90.0%) at the combination of 1 mgL-1) BAP and 2.5 mgL-1)NAA for both the varieties (BINA mung 5 and BINA mung 7). The calli derived from cotyledon, hypocotyls and root tip were cultured in MS medium supplemented with different concentrations of Kn, BAP and/or NAA for shoot induction. Regeneration was achieved only from cotyledon calli at a frequency of 62.50% on 5 mgL-1) BAP and 0.05 mgL-1) NAA. Shoot tip cultured for direct regeneration in the same media containing 5 mgL-1) BAP and 0.05 mgL-1) NAA resulted in 90.0% shoot differentiation in BINA mung 7. The regenerated shoots rooted on MS medium with 0.2 mgL-1) NAA (90.0).DOI: http://dx.doi.org/10.3329/pa.v19i2.16908 Progress. Agric. 19(2): 13 - 19, 2008

Authors: Islam ML , Alam MJ 
Published: November 2013

To observe the effectiveness of short time in-pond nursery of post larvae (PL) on the survival rate and production of shrimp (Penaeus monodon) under modified improved culture system, an experiment was conducted in earthen ponds at Brackishwater Station of Bangladesh Fisheries Research Institute, Khulna. Results of the experiment revealed that short time in-pond nursery of PL provided the significantly higher (p<0.05) survival rate (58%) than direct stocking of PL (47.81%) in the rearing pond. In-pond nursery of PL provided 9.95% better survival rate than direct stocking. The production of shrimp was 661 kg/ha under in-pond nursery of PL and it was 534 kg/ha under direct stocking of PL in rearing ponds. The production of shrimp was also significantly higher (p<0.05) under in-pond nursery system than direct stocking of PL in rearing ponds. Final weight gain and Food Conversion Ratio (FCR) values were similar in both the treatments. Water quality parameters in both stocking systems were insignificant and it was within the range of shrimp culture. In this study, the increment in production under in-pond nursery system was mainly due to the increase of survival rate in the respective treatment was ascertained.DOI: http://dx.doi.org/10.3329/pa.v19i2.16958 Progress.

Comparative Efficiency Analysis of Broiler Farming Under Aftab Bahumukhi Farm Limited Supervision and Farmers Own Management
Authors: Akhter S , Rashid MHA 
Published: November 2013

This study was conducted to assess the comparative efficiency of Aftab Bahumukhi Farm Limited (ABFL) supervised broiler farms and farmers own managed broiler farms. Data were collected from randomly selected 90 broiler farmers of which 45 were ABFL supervised farmers and 45 were own managed farmers. Cobb-Douglas stochastic production function and cost frontier function were applied to determine the technical, allocative and economic efficiency of broiler farming. Technical and economic inefficiency effect models were also estimated. The estimated mean technical efficiency of all farms was 94.06 percent. Whereas it was 94.49 percent for ABFL supervised farmers and 93.66 percent for the own managed broiler farm owners. The estimated mean allocative efficiency was 96.76 percent for all farmers, and 96.51 for ABFL supervised farmers and 96.45 percent for own managed broiler farm owners. The mean economic efficiency was estimated at about 91.60 percent for ABFL supervised farmers, 90.34 percent for own managed farmers and 91.00 percent for all farmers. This implies that the cost of broiler production per farm can be reduced by 9 percent keeping the output constant. The findings reveal that ABFL supervised farmers and own managed farmers were not significantly different in terms of efficiency.DOI: http://dx.doi.org/10.3329/pa.v19i2.16962 Progress.

Production and Promotion of Triticale as a High Quality Fodder and Feed in Small-Scale Dairy Farmers of Bangladesh
Authors: Haque ME , Waddington SR , Sarker ZI , Sarker NR , Akteruzzaman M 
Published: November 2013

In Bangladesh, high quality fodder is scare from December to May for ruminant livestock and feed is expensive throughout the year for poultry. A project was conducted in the cool dry Rabi (December-February) seasons of 2005-06 and 2006-07 to promote triticale (X Triticosecale Wittmack) as a high quality dual-purpose fodder and feed for small-scale dairy and poultry producers. During 2005 and 2006, 504 farm families from six districts in north western and central Bangladesh received training on triticale cultivation and its utilization as a green fodder for dairy cows and for grain. Printed training manuals and visual training materials (including a DVD docudrama) were developed, used in training, and distributed widely. On-farm demonstrations on triticale production were mounted with each trained farm family in two years using a dual-purpose fodder and grain type triticale variety, WRF-7, that earlier on farm research had identified to perform well in Bangladesh. High quality grass fodder was obtained by cutting the vegetative triticale plants either twice (at 35 and 50 days after seeding (DAS)or once (at around 40 days), while the later ratooning tillers produced grain. In 168 farmer demonstrations in 2005-06, the green fodder yield ranged from 4.9 to 20.0 t/ha fresh mass (0.7 t/ha to 2.7 t/ha dry mass) from one cut at 35 DAS and 7 to 28 t/ha fresh mass from two cuts at 35 and 50 DAS. Overall, 62% of farmers reported yields above 10 t/ha of fresh green fodder. A mean grain yield of 1.8 t/ha was obtained from WRF-7 after two cuts on-farm. Straw yields ranged from 0.8 to 7.1 t/ha dry mass. 324 farmers hosted similar demonstrations in 2006-07 and reported higher yields of green fodder, ranging from 7.4 to 33.7 t/ha fresh mass from one cut at 40 to 42 DAS. A higher mean grain yield of 2.8 t/ha was obtained from WRF-7 after one cut for fodder in 2006-07. Assessments of WRF-7 dual-purpose triticale by farmers were very positive, with 97% wanting to grow triticale again in more land ranging from 0.04 ha to 0.81 ha (Table 3). From experience, many farmers decided it was more efficient to cut triticale once for green fodder. Almost all farmers reported benefits to milk production and farm income from feeding triticale fodder to cows. It was concluded that smallholder dairy farmers in North-West Bangladesh can easily produce sufficient amounts of quality fodder for dairy cows and feed for poultry from WRF-7 dual-purpose triticale during periods of severe fodder shortages.DOI: http://dx.doi.org/10.3329/pa.v19i2.16964 Progress.

Les procédures d’accès au logement social [Cadre légal, organisation, pratiques des acteurs]
Authors: Vanoni Didier 
Published: November 2013

Access procedures to social housing. Legal framework, organisation and practice of the parties involved.
This article attempts to describe and analyse the process implemented to enable an applicant household obtain social housing. On the basis of a systematic analysis of the various steps to record the request, then file it in a handling procedure which may result in the award of a unit, the article attempts to highlight the discrepancies, which can be significant, that may arise between the expectations of a system which is predicated by the concept of equity and social efficiency and what actually occurs. Discrepancies are analysed not in terms of breakdowns but as a result of the organisation of a system of awards in ‘ streams’. This mode of operation, which affords a degree of efficiency and fulfils a management rationale, would, if replaced by a rationale focusing more on priorities based on solely social criteria, require many substantial changes in the current system. It would admittedly entail overhauling some rules which provide a framework for award procedures, although above all local stakeholders would have to clarify and share their perception of the role and function they intend to fulfil in social housing as a whole.
Provider-initiated vs. client-initiated HIV testing in Autonomous Province of Vojvodina, Serbia, 2000-2008
Authors: Duric Predrag , Ilic Svetlana , Rajčević Smiljana 
Published: November 2013

Background: This paper describes the changes in Human Immundodeficiency virus (HIV) testing rates in Autonomous Province (AP) Vojvodina, Serbia since 2000 and compares provider-initiated with client-initiated HIV testing. Methodology: Between 2000 and 2008, 66,327 HIV screening tests were reported from AP Vojvodina. During this time HIV testing rates increased from 1.2 per 1,000 inhabitants in 2000, to 7.7 per 1,000 inhabitants in 2008. Results: The results showed an increase in testing as a consequence of increased mandatory testing of surgical patients as well as an upsurge in the use of Voluntary Counselling and Testing (VCT). Pregnant women that were tested represented less than 5% of the overall sample population. Conclusion: Public health efforts in AP Vojvodina to increase HIV testing rates lead to a continuous increase in testing rates, but with different limitations. HIV testing in low prevalence middle income countries could be highly affected by procurement difficulties, low motivation of medical professionals to initiate testing, and opportunities for testing limited to large towns and cities.

Published: November 2013

Introduction: The epidemiology of viral hepatitis during pregnancy is of paramount importance for health planners and program managers. Data on viral hepatitis during pregnancy are not readily available. This study was conducted to assess the extent of seropositivity of hepatitis B, hepatitis C, HIV, and syphilis in pregnant women and to re-evaluate the need for routine antenatal care screening. Methodology: All samples were tested to detect HBsAg by enzyme linked immunosorbent assay (ELISA). Samples were tested to detect anti-HCV by ELISA. Samples were also tested for antibodies to Treponema Pallidum by qualitative rapid plasma reagine (RPR); finally, samples were tested for antibodies to HIV by three different methods as per Strategy III of the National AIDS Control Organization by using different systems of testing to establish a diagnosis of HIV. Results: Seropositivity of hepatitis B was 2.9%, hepatitis C was 0.19%, syphilis was 0.48%, and HIV was 0.38%. Out of the 1038 samples, no co-infection was found between hepatitis B, hepatitis C, syphilis, or HIV. Conclusion: The data from this study can help health professionals to treat antenatal patients more effectively. The data also reinforces the need for establishing effective prevention programs, which could lead to a reduction in the prevalence of HBV, HCV, syphilis, and HIV
