In-vitro study on the hemorheological characteristics of chicken blood in microcirculation

The flow characteristics of chicken blood in a micro-tube with a 100 μm diameter are investigated using a micro-Particle Image Velocimetry (PIV) technique. Chicken blood with 40% hematocrit is supplied into the micro-tube using a syringe pump. For comparison, the same experiments are repeated for human blood with 40% hematocrit. Chicken blood flow has a cell-free layer near the tube wall, and this layer’s thickness increases with the increased flow speed due to radial migration. As a hemorheological feature, the aggregation index of chicken blood is about 50% less than that of human blood. Therefore, the non-Newtonian fluid features of chicken blood are not very remarkable compared with those of human blood. As the flow rate increases, the blunt velocity profile in the central region of the micro-tube sharpens, and the parabolicshaped shear stress distribution becomes to have a linear profile. The viscosity of both blood samples in a low shear rate condition is overestimated, while the viscosity in a high shear rate range is underestimated due to radial migration and the presence of a cell-depleted layer.
Interpreting complex fluvial channel and barform architecture: Carboniferous Central Pennine Province, northern England

The Bashkirian Lower Brimham Grit of North Yorkshire, England, is a fluvio‐deltaic sandstone succession that crops out as a complex series of pinnacles, the three‐dimensional arrangement of which allows high‐resolution architectural analysis of genetically‐related lithofacies assemblages. Combined analysis of sedimentary graphic log profiles, architectural panels and palaeocurrent data have enabled three‐dimensional geometrical relationships to be established for a suite of architectural elements so as to develop a comprehensive depositional model. Small‐scale observations of facies have been related to larger‐scale architectural elements to facilitate interpretation of the palaeoenvironment of deposition to a level of detail that has rarely been attempted previously, thereby allowing interpretation of formative processes. Detailed architectural panels form the basis of a semi‐quantitative technique for recording the variety and complexity of the sedimentary lithofacies present, their association within recognizable architectural elements and, thus, the inferred spatio‐temporal relationship of neighbouring elements. Fluvial channel‐fill elements bounded by erosional surfaces are characterized internally by a hierarchy of sets and cosets with subtly varying compositions, textures and structures. Simple, cross‐bedded sets represent in‐channel migration of isolated mesoforms (dunes); cosets of both trough and planar‐tabular cross‐bedded facies represent lateral‐accreting and downstream‐accreting macroforms (bars) characterized by highly variable, yet predictable, patterns of palaeocurrent indicators. Relationships between sandstone‐dominated strata bounded by third‐order and fifth‐order surfaces, which represent in‐channel bar deposits and incised channel bases, respectively, chronicle the origin of the preserved succession in response to autocyclic barform development and abandonment, major episodes of incision probably influenced by episodic tectonic subsidence, differential tilting and fluvial incision associated with slip on the nearby North Craven Fault system. Overall, the succession represents the preserved product of an upper‐delta plain system that was traversed by a migratory fluvial braid‐belt system comprising a poorly‐confined network of fluvial channels developed between major sandy barforms that evolved via combined lateral‐accretion and downstream‐accretion.
Forest operations for sustainable forestry in the tropics : proceedings of a symposium

Forest soil compaction by log skidding tractors was studied by measuring changes in the surface soil bulk densities in three forest sites where clearfelling operations were being undertaken. The forest surface soil bulk densities in major skid trails after 5 and 10 passes of log skidding tractors were compared with those of undisturbed forest soils. Mean surface soil bulk density of the 0 15 cm depth surface of plantation forest soils which was 0.87 g/cm was increased to 1.16 g/cm after 5, and to 1.36 after 10 passes of log skidding by a farm tractor, and from 0.87 g/cm to 1.53 g/cm after 5 passes and to 1.58 g/cm after 10 passes of log skidding by an articulated skidder. Results indicated that multiple log skidding tractor passes on the forest soils produced significant increases in surface soil bulk densities. The results further indicated that the initial 5 passes on the same route produced most of the soil compaction.

Laboratory and Field Tests of a Novel Three-Stage Personal Dust Sampler for Sampling Three Dust Fractions Simultaneously

This study designed and calibrated a novel three-stage personal dust sampler for sampling inhalable, thoracic, and respirable dust fractions simultaneously. The sampler has an annular inlet as the first stage for inhalable dust sampling, two impactors in the second and third stages to classify thoracic and respirable dusts, respectively, and a final filter. Laboratory calibration tests using monodisperse liquid and solid particles showed that with 100 ppi (pores per inch) PUF (porous polyurethane foam) substrates and at the flow rate of 3.2 L/min, the sampling efficiency curves of both impactor stages matched with the ISO/CEN/ACGIH thoracic and respirable sampling criteria, respectively. The sampler also agreed with the inhalable criterion for particles smaller than 17 μ m while the deviation increases with increasing particle diameter with a maximum of 28% for 27 μ m particles. It was also found that collection efficiency curve for solid particles was similar to that of liquid particles, indicating that there was no solid particle bounce from the PUF substrates for both impactors. This study also compared inhalable, thoracic, and respirable dust concentrations measured by the present three-stage personal dust samplers with those of the Respicon samplers at three different workplaces. Without using a correction factor of 1.5 for the extrathoracic dusts of the Respicon, field results showed that the present three-stage sampler measured three dust fractions comparable to those of the Respicon samplers. The inhalable dust concentrations of the two samplers differed within 5% while the thoracic and respirable concentration differed by less than 22%.
Semiparametric Dynamic Portfolio Choice with Multiple Conditioning Variables

Dynamic portfolio choice has been a central and essential objective for investors in active asset management. In this paper, we study the dynamic portfolio choice with multiple conditioning variables, where the dimension of the conditioning variables can be either fixed or diverging to infinity at certain polynomial rate of the sample size. We propose a novel data-driven method to estimate the optimal portfolio choice, motivated by the model averaging marginal regression approach suggested by Li et al. (2015). More specifically, in order to avoid the curse of dimensionality associated with the multivariate nonparametric regression problem and to make it practically implementable, we first estimate the marginal optimal portfolio choice by maximizing the conditional utility function for each univariate conditioning variable, and then construct the joint dynamic optimal portfolio through the weighted average of the marginal optimal portfolio across all the conditioning variables. Under some regularity conditions, we establish the large sample properties for the developed portfolio choice procedure. Both the simulation study and empirical application well demonstrate the finite-sample performance of the proposed methodology.

Effect of Exercise on Some Haemostatic Parameters Among Students in a Tertiary Educational Institution in Nigeria

This study investigated the effect of exercise on some haemostatic parameters among students from a tertiary institution in Nigeria. Fifty four individuals participated in this study, comprising 28 males and 26 females. Blood was collected from the participants before and after the rigorous exercise and the prothrombin time (PT), activated partial thromboplastin time (APTT) and platelets count (PLT) were analyzed using standard methodology. Results showed mean values before and after the exercise were 217.31 and 238.27 x10 9 /L for female, 228.75 and 240.18 x10 9 /L for male respectively (platelets counts), 14.25 and 12.08 seconds for female, 14.29 and 12.35 seconds for male respectively (prothrombin time) and 31.71 and 24.29 seconds for female and 30.62 and 23.43 seconds for male respectively (activated partial thromboplastin time). Statistically, there was significant variation (P 0.05) for PLT count before and after exercise. PT and APTT showed significant decline after the exercise indicating activation of the coagulation cascade which may lead to hypercoagulability predisposing the subjects to an increased risk of cardiovascular derangement; while PLT showed no variation suggesting no risk of thrombocytopenia or thrombocytosis.
Rapid Identification and Susceptibility Testing of Candida Species, from Urine by MALDI-TOF Mass Spectrometry and VITEK 2

Urinary tract infection(UTI) specially with Candida Spp. , are mostly common in females which are suffering from vaginitis or got the infection through usual gynecology clinic visits and as a nosocomial infection specially in case of using urinary catheterization . Early identification of Candida spp. , is necessary especially in nosocomial UTI and it could help selecting appropriate antifungal for treatment. This study shows that Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry( MALDI-TOF MS) is a reliable tool for fast and accurate identification of Candida spp. ,. 146(4.3%) positive urine samples for yeast infection out of 3,370 samples were submitted to Microbiology laboratory of Hail General Hospital and Hail Maternity Hospital from April 2014 to December 2015 . Specimens were direct microscopically examined for fungal elements and cultured on Sabouraud’s Dextrose agar (SDA) , Candida Chromogenic agar and Blood agar as a routine work identification, isolates were analyzed using (MALDI-TOF MS) and Vitek 2 for identification and susceptibility testing . The results showed that more than 70% of the isolates were C.albicans ,10% C.galabrata,8%C. Kursi, 5%C.dublinsiensis,4% C. lusitaniae and 3% C.tropicalis. In conclusion Vitek 2 susceptibility system AST-YS07 cards and MALDI-TOF MS can be used for accurate routine clinical identification. Comparing to the Vitek 2 , MALDI-TOF MS is easier, faster and more economic for each test but on the other hand unreliable identification due to mixed infection or the specimens containing≤ 10CFU/ml . The databases currently available for both systems should be updated to enhance performance.
Drops on a conical wire

We study experimentally the behaviour of a drop deposited on a conical fibre. It is shown that for wetting liquids, such a drop spontaneously moves towards the region of lower curvature. The driving force is measured and shown to be a gradient of Laplace pressure, which allows us to characterize the dynamics of these self-propelling drops. We conclude by discussing the efficiency of this device for drying a solid initially coated with a liquid film.
Did the 2004 Sumatra–Andaman Earthquake Involve a Component of Tsunami Earthquakes?

Tsunami earthquakes are characterized by (1) slow slip and (2) tsunamis larger than expected from seismic slip. We examine whether the 2004 Sumatra– Andaman earthquake had these features and thus involved a component of tsunami earthquakes. Fitting the effective moment versus frequency curve, we obtain characteristic times τ (Kanamori, 1972) of 70 and 290 sec. The former is on the scaling for normal earthquakes; the latter is longer. In the area off northern Sumatra, by back- projecting the wavefront recorded on the sea surface height (ssh) by the satellite altimetry, we estimate the seaward edge of the fault plane to be located at the deformation front. We then invert the ssh, assuming that the seaward edge of the fault is at this location, and obtain a maximum slip of 40 m, which was estimated to be 15 m previously. This amount of slip, approximately twice the slip estimated seismologically and geodetically, suggests that additional crustal deformation, such as inelastic uplift of the trench sediments, might have occurred near the deformation front. We propose that a similar, possibly slow, slip occurred in the shallow subduction boundary, extending from all over the rupture zone derived by the body-surface waves, with a smaller northward propagation velocity, corresponding to the longer τ . This rupture mode would solve the enigmatic features of this event seen in the seismological and tsunami data. The 2004 Sumatra–Andaman earthquake, having both features (1) and (2) that characterize tsunami eathquakes, likely had a component of tsunami earthquakes.
A Study to Explore Cultural Child Rearing Practices among Women in Village Manakpura, Patiala

Introduction: The child rearing practices differ in communities, depending on their social customs, traditional beliefs and prejudices which may not always be beneficial. Understanding these practices is important for the successful delivery of health messages and services . Aim: The aim of the study was to assess the cultural child rearing practices among women in village Manakpur, Patiala and taking measures (pamphlet distribution) to enhance knowledge of women regarding healthy practices. Material and Methods: This exploratory study was carried out at village Manakpura of dist.Patiala . Total 50 married women having children(0-5)yrs were selected by purposive sampling . After taking written informed consent from them the data was collected using a semistructured interview schedule. Analysis of collected data was done through descriptive statistics . REULTS: 100% women were following cultural child rearing practices where maximum (44%) were in the age group of 25-40 years.89% of them believed in evil eye and practiced either(24%) black thread around the neck or (92%) keeping iron objects under the bed sheet. Although all the subjects believed in giving colostrum to new born, however, 96% did follow prelacteal feeding practice, only 76% started breast feed immediately after birth ,56% continue it till 2years and only 60% initiated supplementary feeding at 6 months. 71% women applied oil, ghee on cord stump for early shedding of cord and to promote healing. 64%applied kajal in the eyes of child. All the subjects believed in immunization &toilet training of child . 90% consulted doctor for child’s sufferings like cough, cold, fever and 20% believe in religious remedies for measles/chickenpox treatments. Conclusion: Different cultures have different child rearing practices, customs and beliefs which affect the upbringing of child. Healthy child rearing practices must be emphasized and faulty practices needs to be corrected by educating the people.
Comparison of embryological development in the threatened Australian lungfish Neoceratodus forsteri from two sites in a Queensland river system

Lungfish are a relict group of basal fishes, survivors of an extensive fossil fauna that first appeared in the Devonian era. The Australian lungfish Neoceratodus forsteri is the only survivor of this fossil fauna in Australia, and is now confined to only 3 natural environments in southeast Queensland, as well as a few lakes and rivers to which the species has been introduced, all in southeast Queensland. The lungfish is under threat from many aspects of human activity in this highly populated part of the state, notably from conversion of the natural riverine environment into large reservoirs for water conservation where conditions are not ideal for adults or for eggs, embryos and hatchling lungfish. Food in reservoir environments is limited for all stages of the life cycle, and refuges for young fish do not exist because the water level fluctuates, especially in spring when lungfish are spawning. Lack of refuges for small fish has been identified as a possible danger to recruitment of young lungfish to the adult population. Comparison of embryological development between eggs and embryos found in unaltered reaches of the Brisbane River to eggs and embryos from a spawning event in Lake Wivenhoe, where lungfish were trapped when the reservoir was built over the Brisbane River in 1984, suggests that lungfish may face more problems than lack of shelter for the young. None of the material collected from Lake Wivenhoe developed normally, possibly because the level of nutrition for parent fish in this lake was so poor that they were unable to produce viable young.
Role of Fluoridation in Caries Prevention among Children-Long Term Follow-Up

It is known that fluoride spray application is an effective method of preventing dental caries permanent dentition. Material and methods: Our research of 355 school children 12 years old showed that use the spray preparation of fluoride 5% Sodium Fluoride 22.600 ppm had a remarkable anti-caries effect. In a control group we had 198 school children, girls 40.4% and boys 59.6%. In fluoridation group we had 157 school children, girls 40.1% and boys 59.9% of the same age. Resultants: Ninety percent of examined children had caries. DMFS (decayed, missing and filled surfaces) were from the data analyses we see that in the control group at the beginning of the study the index DMFS =4.5 while at the end of the study the index increases DMFS = 5.27. The fluoridation group at the beginning of the study presents a caries experience DMFS = 4.2 and at the end of the study DMFS =4 decreased respectively. Comparison of averages of DMFS at the end of study between control group and fluoridation group have shown the reduction of caries (p<0.05). Conclusion: The fluoride spray 5% NaF resulted effective in reduction of dental caries of permanent teeth in school children.
Properties and observability of glitches and anti-glitches in accreting pulsars

Several glitches have been observed in young, isolated radio pulsars, while a clear detection in accretion-powered X-ray pulsars is still lacking. We use the Pizzochero snowplow model for pulsar glitches as well as starquake models to determine for the first time the expected properties of glitches in accreting pulsars and their observability. Since some accreting pulsars show accretion-induced long-term spin-up, we also investigate the possibility that anti-glitches occur in these stars. We find that glitches caused by quakes in a slow accreting neutron star are very rare and their detection extremely unlikely. On the contrary, glitches and anti-glitches caused by a transfer of angular momentum between the superfluid neutron vortices and the non-superfluid component may take place in accreting pulsars more often. We calculate the maximum jump in angular velocity of an anti-glitch and we find that it is expected to be about 1E-5 - 1E-4 rad/s. We also note that since accreting pulsars usually have rotational angular velocities lower than those of isolated glitching pulsars, both glitches and anti-glitches are expected to have long rise and recovery timescales compared to isolated glitching pulsars, with glitches and anti-glitches appearing as a simple step in angular velocity. Among accreting pulsars, we find that GX 1+4 is the best candidate for the detection of glitches with currently operating X-ray instruments and future missions such as the proposed Large Observatory for X-ray Timing (LOFT).
Does the Endowment of Contributors Make a Difference in Threshold Public-Good Games?

We investigate experimentally whether the endowment of potential contributors changes outcomes in threshold public-good games. We find that the variance in contributions is significantly reduced for low and high levels of endowment in comparison with an intermediate level of endowment. This difference emerges with experience. Evidence on whether the level of endowment influences the success rate at providing public goods is more mixed. We provide, however, a measure of endowment size that correlates with success rate. Our interpretation suggests that people find it hardest to coordinate on the provision of threshold public goods when endowments are of intermediate size. By intermediate we mean that the endowment is small enough that people need to contribute relatively a lot to fund the good, but also large enough that no one person is critical in providing the good.
Large neighbourhood Benders ’ search

A general enhancement of the Benders’ decomposition algorithm can be achieved through the improved use of large neighbourhood search heuristics within mixed-integer programming solvers. While mixed-integer programming solvers are endowed with an array of large neighbourhood search heuristics, their use is typically limited to finding solutions to the Benders’ decomposition master problem, which may be of poor quality for the original problem or even infeasible. Given the lack of general frameworks for Benders’ decomposition, only ad hoc approaches have been developed to enhance Benders’ decomposition through the use of large neighbourhood search heuristics. Within the solver SCIP, a Benders’ decomposition framework has been developed to achieve a greater integration with the internal large neighbourhood search heuristics. Benders’ decomposition is employed to solve the auxiliary problems of all large neighbourhood search heuristics, the Large Neighbourhood Benders’ Search, to improve the quality of the identified solutions and generate additional cuts that can be used to accelerate the convergence of the main solution algorithm. The computational results demonstrate the performance improvements achieved by this general enhancement technique for Benders’ decomposition.
