Factors associated with pleurisy in pigs
A case-control investigation was undertaken to determine management and health related factors associated with pleurisy in slaughter pigs in England and Wales.
The British Pig Executive Pig Health Scheme database of abattoir pathology was used to identify 121 case (≥10% prevalence of pleurisy on 3 or more assessment dates in the preceding 24 months) and 121 control units (≤5% prevalence of pleurisy on 3 or more assessment dates in the preceding 24 months). Farm data were collected by postal questionnaire. Data from respondents (70 cases and 51 controls) were analysed using simple logistic regression models with Bonferroni corrections. Limited multivariate analyses were also performed to check the robustness of the overall conclusions.
Management factors associated with increased odds of pleurisy included ‘no all-in all-out pig flow’ (OR 9.3, 95% confidence interval [CI]: 3.3–29), ‘rearing of pigs with an age difference of >1 month in the same airspace’ (OR 6.5 [2.8–17]) and ‘repeated mixing’ (OR 2.2 [1.4–3.8]) and ‘moving’ (OR 2.2 [1.5–3.4]) of pigs during the rearing phase. Those associated with decreased odds of pleurisy included ‘filling wean-to-finish or grower-to-finish systems with piglets from ≤3 sources’ (OR 0.18 [0.07–0.41]) compared to farrow-to-finish systems, ‘cleaning and disinfecting’ of grower (ORs 0.28 [0.13–0.61] and 0.29 [0.13–0.61]) and finisher (ORs 0.24 [0.11–0.51] and 0.2 [0.09–0.44]) accommodation between groups, and ‘extended down time’ of grower and finisher accommodation (OR 0.84 [0.75–0.93] and 0.86 [0.77–0.94] respectively for each additional day of downtime). This study demonstrated the value of national-level abattoir pathology data collection systems for case control analyses and generated guidance for on-farm interventions to help reduce the prevalence of pleurisy in slaughter pigs

A.R Baswedan dan PAl: Potret Nasionalisme Warga Keturunan perspektif sosiopolitik historis
In this article, the authors review about A.R. Baswedan
and his movement through the Arab Party of Indonesia (PAl).
A.R Baswedan is an Arab descendant known as the pioneer
of independence of the Republic of Indonesia. The author
through historical socio-political studies found that A.R
Baswedan is an example of Arabic descent who counter
Arabism and views between the Arab descendants and the
descendants of indigenous Indonesians are the same or
equal and the same fate. They both have one nationality,
Indonesia. This fusion attitude in the Indonesian citizenship
and nationality equation is evident in its movement within
the PAl.

THE EFFECT OF TYPE OF FEED AND SLAUGHTER AGE ON THE PERFORMANCES AND CARCASS CHARACTERISTIC OF MALE ARAB CHICKEN
An experiment was conducted to evaluate the effect of type of feed and slaughter age on the performances
and carcass characteristics of male Arab chicken. Thirty six male Arab chicken of seven weeks old were
divided into two groups, each group consisted of three cages with six chicken in each group. Two types of
ration consisted of Ration One (Par-S + corn) containing 2904 kcal ME and 17 % CP, and Ration Two (BR
II) containing 3100 kcal ME and 19% CP. The chicken were raised for seven weeks, weekly weighed, and
randomly taken for slaughter at 12 and 14 week old. The data collected were performances and carcass
characteristics of the chicken. The data were analyzed using analysis of variance of completely randomised
design. The results showed that the chicken fed BR II consumed more protein and energy (483.7 g CP and
7868.8 kcal ME) compared to the chicken fed BR I (444.0 g CP and 7586.1 kcal ME). Besides, the chicken
fed BR II produced heavier final body weight (1142.5 g) than the chicken fed with BR I (1048.6 g) (P <
0,05). Type of ration affected the tenderness of chicken. Slaughter age influenced carcass weight and
carcass physical composition of the chicken (P<0.05). Slaughter age affected the physical characteristic of
meat. It could be concluded that male Arab chicken fed ration containing higher CP and ME (higher feed
density) consumed more protein and energy, and finally had heavier final body weight. Slaughter age influenced
carcass weight, carcass physical composition and meat characteristics of the male Arab chicken
A STUDY OF ANAEROBIC FILTER FOR DOMESTIC AND SLAUGHTER HOUSE WASTE WATER TREATMENT
To study the feasibility of anaerobic filter in raw sewage and slaughter house wastewater treatment, slaughter house wastewater treatment, a batch flow pilot plant was designed. In phase one, with a detention time of 3-days and no mixing, the maximum reduction in COD was 23%. In the second phase, with a detention time of 2-days and complete mixing, glucose was added to the raw sewage, the reduction in COD and TSS were 97% and 89%. In the third run, for a detention time of 1-day and no changes in other conditions, COD and TSS reductions were 94 and 92%. In the fourth phase with a detention time of 16 hours COD and TSS of effluent were much more than the last three phases, so it was decided to stop this phase. In the fifth run, slaughter house wastewater was treated. With a detention time of 2-days, reductions in COD and TSS were 98 and 86%. In the last phase, slaughter house wastewater was added to row sewage 50-50. With a detention time of 1-day, reductions in COD and TSS were 80 and 98%
A.R. Luria: Ideas and Prospects of Their Development in Pedagogical Psychology of the Twenty-first Century
A.R. Luria’s ideas are well-known and recognized both in Russia and abroad. Scientists from different countries are actively working in neuropsychology, a part of the psychological science developed by A.R. Luria. The author has shown the relevance and importance of the neuropsychological approach to the pedagogical psychology problems and the availability to choose an adequate educational and nurturing strategy from these standpoints. The study seeks to rethink and assess the importance of A.R. Luria’s main ideas from the modern pedagogical psychology’s standpoints. The characteristic of the main theoretical provisions has been set forth based on the analysis of A.R. Luria’s academic papers and the main directions and prospects for the development of A.R. Luria’s ideas in the modern psychological pedagogical science have been determined. A.R. Luria’s academic papers most sought by the modern researchers have been noted. The study is based on the materials of the thesis researches on the pedagogical psychology problems conducted in the beginning of the twenty-first century, A.R. Luria’s papers, the publications of other researchers who have studied his contribution to the psychological science. The study results show that A.R. Luria has significantly contributed to the development of the pedagogical psychology problems. A.R. Luria’s ideas on the interaction of the humanitarian and science knowledge in the human comprehensive study, the cultural and historical understanding of the psychical functions development, and the language evolution in the music language study for the musical education development seem most promising for the pedagogical psychology development. Note has been taken of the importance of A.R. Luria’s ideas for the elaboration of the relevant problems of the training and development of a person at any age; the study of individual and typical features in mastering a foreign language; the study of the semantics of speech and means of coding meanings in the context of professional training of psychologists and teachers, specialists in the field of artistic creativity. The analysis of A.R. Luria’s main ideas facilitates the deeper understanding of the modern problems of the pedagogical psychology theory and practice
Incorporation of acceleration effects into the one-dimensional-turbulence model, with application to turbulent combustion and shock-turbulence interactions
One-dimensional turbulence (ODT) is a stochastic simulation in which 3D turbulence effects are captured on a notional 1D line of sight by introducing instantaneous spatial re-arrangements (maps) that represent advection by notional turbulent eddies. These eddy events incorporate the possibility of kinetic-energy changes that are equal and opposite to changes of other forms of energy such as the gravitational potential energy change due to a re-arrangement of a vertical density profile. This illustrates that motion aligned with an applied force, in this case gravitation , can be associated with energy change. Using this principle, we 1) present a model of turbulence interaction with the dilatational acceleration caused by thermal expansion in flames and show results for a turbulent counterflow flame with comparison to DNS and 2) present a model for shock-induced turbulence and show results for mixing width growth in a shock tube with comparison to experiments
ODTLES: A multi-scale ansatz for highly turbulent flows
We use ODTLES, a multi-dimensional extension of the One-Dimensional-Turbulence model (ODT). ODT describes turbulent advection on a 1D sub-domain using a stochastic process for turbulent advection. These 1D sub-domains are coupled to obtain a 3D approach. ODTLES is applied to channel flow. Preliminary results for the pdf of the wall shear stress are compared to DNS

The IPHAS catalogue of H alpha emission-line sources in the northern Galactic plane
We present a catalogue of point-source H alpha emission-line objects selected from the INT/WFC Photometric Ha Survey (IPHAS) of the northern Galactic plane. The catalogue covers the magnitude range 13 <= r' <= 19.5 and includes Northern hemisphere sources in the Galactic latitude range -5 degrees < b < 5 degrees. It is derived from similar to 1500 deg(2) worth of imaging data, which represents 80 per cent of the final IPHAS survey area. The electronic version of the catalogue will be updated once the full survey data become available. In total, the present catalogue contains 4853 point sources that exhibit strong photometric evidence for Ha emission. We have so far analysed spectra for similar to 300 of these sources, confirming more than 95 per cent of them as genuine emission-line stars. A wide range of stellar populations are represented in the catalogue, including early-type emission-line stars, active late-type stars, interacting binaries, young stellar objects and compact nebulae.
The spatial distribution of catalogue objects shows overdensities near sites of recent or current star formation, as well as possible evidence for the warp of the Galactic plane. Photometrically, the incidence of Ha emission is bimodally distributed in (r' - i'). The blue peak is made up mostly of early-type emission-line stars, whereas the red peak may signal an increasing contribution from other objects, such as young/active low-mass stars. We have cross-matched our H alpha-excess catalogue against the emission-line star catalogue of Kohoutek & Wehmeyer, as well as against sources in SIMBAD. We find that fewer than 10 per cent of our sources can be matched to known objects of any type. Thus IPHAS is uncovering an order of magnitude more faint (r' > 13) emission-line objects than were previously known in the Milky Way
