EFFECT OF TRANSPORTATION ON THE EXPRESSION OF HEAT SHOCK PROTEIN 70 AND MEAT QUALITY OF BROILERS DURING SUMMER

The aim of this study was to determine the effects of pre-slaughter transport during summer on stress indicators, heat shock protein 70 (HSP70) expression and meat quality of broilers. We found that short-distance transport under high ambient temperature conditions induced the release of plasma corticosterone (CORT), creatine kinase (CK) and lactate dehydrogenase (LDH), which are significant indicators of stress conditions. The expression of HSP70 in the transport group was significantly lower than in the control group (P < 0.05). Moreover, immunofluorescence showed that the distribution of HSP70 shifted from cytoplasm and surface of membranes to extracellular matrix after stress. In addition, meat quality in the transport group showed a pale, soft and exudative (PSE)-like syndrome. Our research suggests that HSP70 may be associated with an unknown mechanism that leads to meat quality deterioration following acute stress.
Anaerobic Digestion of Slaughterhouse Wastewater: A Kinetics Study

Anaerobic digestion was used to study the treatment of slaughterhouse industrial wastewater (SHW). Digestion period of 50 days was observed. This hydraulic retention time (HRT) was used because that was when negligible biogas production was obtained with. The gas was collected in a measuring cylinder by the use of downward displacement of water. The maximum volume of biogas produced was 537ml. Some of the characteristics of the wastewater such as chloride, total nitrogen, calcium were within the limit prescribed by WHO (world health organization). The kinetic parameters such as maximum rate of substrate utilization (K), half velocity or saturation constant (KS), endogenous decay coefficient (Kd), biomass or microbial growth yield (Y) and maximum specific microorganism growth rate (μmax) were evaluated as 31.847day 1, 25,347.77mg/l, 0.009day 1, 0.034 mg/mg and 1.073day 1 respectively. The kinetics data of anaerobic digestion of the wastewater fitted first order kinetic model. The net specific growth rates (μnet) reduced with time. The values of the kinetics parameters showed that digestion of SHW did not require inoculation of the feed with microorganism to increase the rate of digestion.

Genetic Analysis of Mutations Causing Borrelidin Resistance

Mutations leading to borrelidin resistance in Escherichia coli by overproduction of threonyl-transfer ribonucleic acid synthetase were analyzed genetically. The regulatory mutations were closely linked to the threonyl-transfer ribonucleic acid synthetase structural gene (thrS), located clockwise to it. The mutation that causes the threefold-increased enzyme level was more distant from thrS than the mutation responsible for the ninefold overproduction. Both mutations were cis dominant in merodiploid strains, indicating that they affected promoter-operatorlike control elements. Overproduction was restricted to threonyl-transfer ribonucleic acid synthetase and was not observed for the products ofgenes neighboring thrS (e.g., infC, pheS, pheT, and argS), providing evidence that thrS is transcribed singly and that gene amplification is not a likely basis for increased thrS expression.
Modified Vanstone’s Construction of lightweight MAC for Vehicular On-Board IT Systems

We propose a lightweight construction, a modification of Vanstone’s MAC construction, for the message authentication of the communication between Electronic Control Units (ECUs) in distributed car control systems. The proposed approach can solve the task of error control and authentication in unified algorithmic technology, called MAC (Message Authentication Code) with ECC (Error Correction Code). We follow a provable approach in the design of the cryptographic primitive, where we quantify the security measures in the parameters of the system. Provable security approaches are missing in the field of secure in-vehicle communication.
Percutaneous surgery in the treatment of Haglund syndrome

Objective: The present study aimed to verify the state of the art of minimally invasive percutaneous surgical treatment for Haglund syndrome. Methods: This systematic review of the literature was based on a bibliographic survey in the PubMed, Medline and Embase databases. The descriptors "Haglund syndrome", "Haglund", "Achilles", "Minimally invasive", "Percutaneous surgery" and "Osteotomy" were used, in addition to the filters "Randomized Controlled Trial", "Randomized Clinical Trial", "Meta-Analysis", "Systematic Reviews", "Reviews", and "Clinical Trial". Results: A total of 37 articles were included. The total number of patients with Haglund syndrome treated in the included studies was 831 and 920. The mean patient age was 46.6 years (range, 28.7 to 61) and 58% were men. A higher success rate and a lower rate of complications were reported in men, and physically active patients had better treatment results. The mean success rate for minimally invasive percutaneous procedures was 83.4% (range 66 to 100%). Overall patient satisfaction was 77.5% (range 60 to 95%) and the complication rate was 6.3% (range 0 to 23%). Conclusion: Despite a lack of studies with the recommended evidence level, minimally invasive and percutaneous surgical treatments seem to be a good option for patients with Haglund syndrome when conservative treatment fails. Level of Evidence III; Therapeutic Studies; Systematic Review of Level III Studies.
Appendix for AABO: Adaptive Anchor Box Optimization for Object Detection via Bayesian Sub-sampling Optimal FPN Hyper-parameters in Preliminary Analysis In preliminary analysis, we search for better RPN head architecture in FPN

In preliminary analysis, we search for better RPN head architecture in FPN [6] as well as anchor settings simultaneously, to compare the respective contributions of changing RPN head architecture and anchor settings. The optimal hyper-parameters are shown in Table 1. Since the search space for RPN head architecture and anchor settings are both relatively small, the performance increase is not very significant.
Estimating the cancer risk and mortalities induced by routine digital radiography examinations on patient of different ages in Mazandaran province

Background: The aim of this study was to estimate the cancer risks and mortalities of different types induced by routine examinations of digital radiography for one year in Mazandaran province, Iran. Materials and Methods: Radiation parameters and calculated entrance skin dose (ESD) values of 13 digital radiographic examinations were collected from 2340 patients at 18 high-patient-load radiography centers. Organ mean doses were estimated based on the collected parameters applying PCXMC software. The BEIR VII-Phase 2 model was used to calculate the induced cancer risks and mortalities of various cancer types at different ages. Results: The average ± standard deviation (SD) lifetime risks (incidence probability in 100,000 people) induced by radiations from radiography examinations for one year was 51.29±4.73 and 99.62±7.36 for new-born males and females, respectively. The lifetime cancer risk decreased with age and reached 3.77±0.62 and 4.88±0.07 for 80-year men and women, respectively. The average lifetime risks of mortality due to cancers induced by annual radiographies were obtained at 14.18±1.62 and 22.83±2.55 for new-born males and females, respectively. This risk reduced with age and was reached 1.97±0.27 and 2.45±0.38 for men and women at the age of 80 years, respectively. Conclusion: Our results showed that there are low but significant risks of cancer incidence for patients undergoing digital radiography, which included a large percentage of the population in Mazandaran province, especially for children and newborns. Therefore, further efforts like appropriate patient setup and beam geometry should be carried out to decrease patient doses.
Advancing on large-scale trends of apparent organic matter reactivity in marine sediments and patterns of benthic carbon transformation

Abstract. Constraining the mechanisms that control organic matter (OM) reactivity and, thus, degradation, preservation and burial in marine sediments across spatial and temporal scales is key to understanding carbon cycling in the past, present, and future. However, we still lack a quantitative understanding of what controls OM reactivity in marine sediments and, as a result, how to constrain it in global models. To fill this gap, we quantify apparent OM reactivity (i.e., model-derived estimates) by extracting reactive continuum model parameters (a and v) from observed benthic organic carbon and sulfate dynamics across 14 contrasting depositional settings distributed over five distinct benthic provinces. Our analysis shows that the large-scale range in apparent OM reactivity is largely driven by the wide variability in parameter a (10−3
Influence of Trainees’ Entry Qualification on Skill Development for Kenya’s Realization of Her Development Agenda

The purpose of the study was to examine how entry qualifications of trainees at Technical Vocational, Education and Training (TVET) institutions impact on skill development for Kenya’s development agenda. The study was a qualitative case study of three cohorts (2016, 2017 and 2018) being the groups that had done national examinations set by Kenya National Examinational Council (KNEC) at the time the study was carried out. Data was gathered using questionnaires and document analysis. Data analysis involved verification of the entry requirements for one to be enrolled in a given course vis-a-vi the policy governing admissions, actual enrolments in the courses offered and trainees’ performances at the Kenya National Examinational Council examination. The study established that there was strong correlation of 0.798 in a 2 tailed test between trainees’ initial qualifications and academic achievement, a measure of skill formation. However initial entry qualification of trainees was generally low with over 60 percent of the trainees having scored grade D+ and below in their pre-entry examination leading to poor academic achievement, a state that was more pronounced in Science oriented courses. It was further established that the main cause of low achievement of the trainees in the science oriented courses investigated were that the trainees had registered for the courses based on the minimum grade requirement but had poor grades in Science subjects. These findings indicated that Kenya was unlikely to achieve a manpower development needs if this trend continues. As such the study recommends for the need to revise minimum requirements in the cluster subjects to be considered for admission to various courses. The institutes should provide proper career guidance for prospective trainees to help them make informed choices regarding courses to be pursued not only on the basis of their interests but also on their academic abilities as demonstrated in their entry examination performances.
Office Physical Proximity and Employee Efficiency of Manufacturing Companies in Port Harcourt

nrdajpapers@gmail.com 47 | P a g e Abstract: This study examined the relationship between office physical proximity and employee efficiency of manufacturing companies in Port Harcourt. The study adopted the cross-sectional survey design. Primary data was generated through structured questionnaire. The population of the study was 253 employees of seven (7) selected manufacturing companies in Port Harcourt. The sample size of 154 was determined using the Taro Yamane’s formula for sample size determination. The research instrument was validated through supervisor’s vetting and approval while the reliability of the instrument was achieved by the use of the Cronbach Alpha coefficient with all the items scoring above 0.70. The hypotheses were tested using the Spearman’s Rank Order Correlation Coefficient. The tests were carried out at a 95% confidence interval and a 0.05 level of significance. The findings of the study revealed that there is a significant relationship between office physical proximity and employee efficiency of manufacturing companies in Port Harcourt. The study thus recommends manufacturing companies should provide sufficient and flexible furniture supported by suitable height panels to facilitate communication as well as visual and acoustical privacy.
TITLE : Hedonic pricing analysis of the Norwegian hotel industry : consumers willingness to pay for environmentally certified hotels

With consumers becoming more environmentally conscious and governments implementing regulations to combat global warming, hotel owners need to consider making their practice more sustainable. By analyzing the Norwegian hotel industry, we estimate if the consumers are willing to pay more for a stay at an environmentally friendly hotel, than a hotel without sustainability measures. Collecting data on characteristics that influence the final price for a stay at 259 different hotels spread across Norway, we create a hedonic pricing model to calculate the implicit value of being certified as environmentally friendly. We find that consumers are willing to pay a premium of 80kr-161kr for hotels certified by Miljøfyrtårn but need 104kr-109kr in compensation to accept a hotel certified by Svanemerket.
Extrapolating fiber crossings from DTI data. Can we gain similar information as HARDI?

High angular resolution diffusion imaging (HARDI) has proven to better characterize complex intra-voxel structures compared to its predecessor diffusion tensor imaging (DTI). However, the benefits from the modest acquisition costs and significantly higher signal-to-noise ratios (SNRs) of DTI make it more attractive for use in clinical research. In this work we use contextual information derived from DTI data, to obtain similar fiber crossings as the ones recovered with the HARDI reconstruction techniques. We conduct a synthetic phantom study under different angles of crossing and different SNRs. We compare the extrapolated crossings from contextual information with HARDI data. We qualitatively corroborate our findings from the phantom study to real human data. We show that with extrapolation of the contextual information, the obtained crossings are similar to the ones from the HARDI data, and the robustness to noise is significantly better.
Electron-energy-loss spectroscopy and X-ray absorption spectroscopy as complementary probes for complex f-electron metals: cerium and plutonium

In this paper, we demonstrate the power of electron-energy-loss spectroscopy (EELS) in a transmission electron microscope by investigating the electron structure of two f-electron metals: Ce and Pu. It is shown that EELS in a transmission electron microscope may be used to circumvent the difficulty of producing single-phase or single-crystal samples owing to its high spatial resolution, and that diffraction patterns and images can be acquired, providing unambiguous phase determination when acquiring spectra. EELS results are supported by synchrotron-radiation-based X-ray absorption, multielectron atomic spectral simulations, and local density approximation calculations based on density-functional theory with the generalized gradient approximation. For Ce, it is shown that changes in {111} stacking sequences can drive substantial modifications in the electronic structure of close-packed phases of Ce that have similar atomic volumes, contrary to previous assumptions in literature. For Pu, it is shown that Russell–Saunders (L–S) coupling fails for the 5f states and that either a j–j or an intermediate scheme must be used for the actinides because of the considerable spin–orbit interaction in the 5f states. We present a model showing how the 5f states behave along the light actinide series.

Magpie: Python at Speed and Scale using Cloud Backends

Python has become overwhelmingly popular for ad-hoc data analysis, and Pandas dataframes have quickly become the de facto standard API for data science. However, performance and scaling to large datasets remain significant challenges. This is in stark contrast with the world of databases, where decades of investments have led to both sub-millisecond latencies for small queries and many orders of magnitude better scalability for large analytical queries. Furthermore, databases offer enterprise-grade features (e.g., transactions, fine-grained access control, tamper-proof logging, encryption) as well as a mature ecosystem of tools in modern clouds. In this paper, we bring together the ease of use and versatility of Python environments with the enterprise-grade, high-performance query processing of cloud database systems. We describe a system we are building, coined Magpie , which exposes the popular Pandas API while lazily pushing large chunks of computation into scalable, efficient, and secured database engines. Magpie assists the data scientist by automatically selecting the most efficient engine (e.g., SQL DW, SCOPE, Spark) in cloud environments that offer multiple engines atop a data lake. Magpie ’s common data layer virtually eliminates data transfer costs across potentially many such engines. We describe experiments pushing Python dataframe programs into the SQL DW, Spark, and SCOPE query engines. An initial analysis of our production workloads suggest that over a quarter of the computations in our internal analytics clusters could be optimized through Magpie by picking the optimal backend.
Electrospinning of Chitosan

Summary: An electrospun nonwoven fabric of a cationic polysaccharide, chitosan, was successfully prepared. The present study focuses on the effect of the electrospinning solvent and the chitosan concentration on the morphology of the resulting nonwoven fabrics. The solvents tested were dilute hydrochloric acid, acetic acid, neat formic acid and trifluoroacetic acid. As the chitosan concentration was increased, the morphology of the deposition on the collector changed from spherical beads to interconnected fibrous networks. The addition of dichloromethane to the chitosan-TFA solution improved the homogeneity of the electrospun chitosan fiber. Under optimized conditions, homogenous (not interconnected) chitosan fibers with a mean diameter of 330 nm were prepared. Effects of the coexisting dichloromethane (MC) in the prespun chitosan-TFA solution on the morphology of the electrospun chitosan fibers. The volume ratio of TFA:MC was 70:30 (×5 000).
The Impact of Controlling Families and Foreign Institutional Investors on Non-financial Performance Measures

This study examines how controlling family ownership and foreign institutional ownership affect companies’ use of non-financial performance measures (NFPMs). We conducted two surveys (one in 2005 and the other in 2015) with publicly listed companies and used archival data from 254 respondent companies in Taiwan. Our results from the 2005 data show that foreign institutional ownership increases the use of NFPMs, while family control is not associated with the extent of NFPM use. After 10 years, the full sample shows that both controlling families and foreign institutional ownership have enhanced NFPM use. Furthermore, the full sample data reveal that controlling families demand more NFPMs when the CEO is not a family member. These results suggest that foreign institutional ownership increases the use of non-financial performance measures, shedding additional light on the trade-off between monitoring mechanisms and the design of optimal performance measures.
Bone Formation and Skeletal Aging - The effects of oxygen tension and DNA repair

textabstractAging is a process that affects everybody and importantly, affects all cells and therefore all the tissues in our body. In the worst cases, tissue aging leads to organ failure and death; in other cases, the effects of aging are more subtle and less dramatic. In our tissue of choice – bone and the skeletal system - aging manifests in the form of osteoporosis, low bone mineral density and a higher risk of fractures, all contributors to a higher morbidity [1]. There are several theories applicable to the process of aging, of which the free radical theory of aging is one of the oldest and well-studied. This theory, first proposed by Denham Harman in the 1950’s, states that organisms age because cells accumulate free radical damage over time [2]. Free radicals are atoms or molecules that have a single unpaired electron in their outer shell. Many biologically relevant free radicals are highly reactive and can be produced by the cell’s metabolic mechanisms. Free radicals can cause intracellular damage to DNA and proteins.
