Epidemiology of Campylobacter Jejuni.

A study was conducted to determine the prevalence of Campylobacter jejuni in various avian species and humans. Cloacal swabs derived from birds submitted to the Louisiana Veterinary Medical Diagnostic Laboratory for necropsy examination during the period February 1987 through July 1 988 were routinely cultured for Ĉ _ jejuni using Butzler's selective medium. Campylobacter jejuni was isolated from 10.1% of the cases examined. The isolation rate was 25.2% in Galliformes, 12.9% in Anseriformes, 8.3% in Columbiformes, 7.7% in Falconiformes, and 0.6% in Psittaciformes. None of the other orders of birds examined yielded Ĉ _ j ej un i. Prevalence data demonstrated that Galliformes are important reservoirs of jejuni infection for humans and that Psittacines do not represent any significant risk to human contacts. Prevalence of Ĉ _ jejuni in diarrheic patients was studied during a one-year period, from August 1987 through July 1988. Of a total 1423 fecal samples cultured, 38 yielded C^ jejuni giving an isolation rate of 2.7%. This is comparable to the 2.6% prevalence rate obtained in a similar study in Texas. Prevalence rate for Salmonella spp. during the same study was 2.0%. Seasonal fluctuation in prevalence of C_. _ jejuni in humans was demonstrated, with a peak in Summer and a smaller increase in Winter. A high incidence was observed in children under 5 years, and in adults aged 21 to 25 and 31 to 40 years. The Penner serotyping system was able to classify 91.1% of the isolates obtained from human patients and 96.7% from avian species. Fourteen of the 16 serotypes considered in the present study were identified among the isolates. Eight of the serotypes were common to both avian species and humans indicating the potential for zoonotic transmission of Cj_ jejuni infection from birds. Serotype Penner 1 was isolated only from avian species indicating the low risk this serotype poses for humans while serotype Penner 10 was isolated mainly from humans suggesting that this serotype is transmitted by direct contact or acquired from non-avian species. Two serotypes (Penner 5 and 10) showed consistent production of enterotoxins. Toxin was produced by 75% of human and 85% of avian isolates demonstrating the considerable potential for human infection with toxigenic
Robustness Spatiotemporal Clustering and Trend Detection of Rainfall Erosivity Density in Greece

Soil erosion is affected by rainfall, among other factors, and it is likely to increase in the future due to climate change impacts, resulting in higher rainfall intensities. This paper evaluates the impact of the missing values ratio on the computation of the rainfall erosivity factor, R, and erosivity density, ED. The paper also investigates the temporal trends and defines regions of Greece with a similar monthly distribution of ED using an unsupervised method. Preprocessed and free from noise and errors rainfall data from 108 stations across Greece were extracted from the Greek National Bank of Hydrological and Meteorological Information. The rainfall data were analyzed and erosive rainfalls were identified, their return period was determined using intensity–duration–frequency curves and R and ED values were computed. The impact of missing data in the computation of annual values of R and ED was investigated using a Monte Carlo simulation. The findings indicated that missing rainfall data resulted in a linear underestimation of R, while ED is more robust. The trends in ED timeseries were evaluated using the Kendall’s Tau test and their autocorrelation and partial autocorrelation were computed for a small subset of stations using criteria based on the quality of data. Furthermore, cluster analysis was applied to a larger subset of stations to define regions of Greece with similar monthly distribution of ED. The findings of this study indicate that: (a) ED should be preferred for the assessment of erosivity in Greece over the direct computation of R, (b) ED timeseries are found to be stationary for the majority of the selected stations, in contrast to reported precipitation trends for the same time period, (c) Greece is divided into three clusters/areas of stations with distinct monthly distributions of ED.
Quality of life of patients with knee osteoarthritis

Introductions: Osteoarthritis (OA) is a non-inflammatory degenerative disorder of the joint. It has negative impact on health related quality of life (QOL), both in physical and mental health. This study aimed to assess QOL of patient with knee osteoarthritis. Methods: A descriptive cross-sectional study was conducted in outpatient department of orthopedic in Patan hospital, Patan Academy of Health Sciences. Non-probability purposive sampling technique was used. Data was collected from 21st July to 18th August 2017 among 125 knee osteoarthritis patients by face-to-face interview using structured interview. Results: Overall QOL of patients with knee osteoarthritis was good in mental health component mean score (62.09) and poor in physical health with a mean score of (38.18). The physical component of QOL was significantly associated with age (p<0.04) and occupation (p<0.001). There was no association between independent variable and mental component of QOL. Conclusions: The significant proportion of the patients have poor quality of life in physical health component, but majority of patients have good mental health.
Boron application affecting the yield and fatty acid composition of soybean genotypes

The effects of different boron (B) dosages (0, 2 and 12 mg B/kg) were determined on four soybean (Glycine max (L.) Merr. ) cultivars, namely 13935, Türksoy, ME 3399 and Deficiency. B contents of the dried plant samples, dry weight, total oil, biomass, seed yield (g/pot), seed protein contents and seed fatty acid compositions were estimated. The seed protein content and shoot dry weight of soybean cultivars increased and decreased with B supply, respectively. The seed oil of cv. Türksoy had the highest ratio of stearic and oleic acids under 2 mg B/kg treatment. The highest total oil content under 12 mg B/kg treatment was observed in cv. Deficiency with 8% higher total oil content. The ratio of saturated fatty acids to unsaturated fatty acids decreased in cvs. 13935 and ME 3399, and increased in cvs. Türksoy and Deficiency at B treatments. Seeds oil of cvs. 13935 and ME 3399 showed the highest α-linolenic acid levels under 2 mg B/kg and 12 mg B/kg soil treatment, respectively. The study revealed that high concentrations of boron had a diminishing effect on seed yield (except cv. Türksoy), increasing effect on protein content and variable effect on saturated and unsaturated fatty acid compositions. This specifies the involvement of boron in the formation of seed protein and fatty acids in soybean. However, detailed research is required to understand the mechanisms behind the process.
Fatty acids profile and oxidative stability of eggs from laying hens fed diets containing hemp seed or hempseed cake

High levels of polyunsaturated fatty acids (PUFAs) are desirable in eggs for its nutritional quality, but render them vulnerable to oxidation. The aim of this trial was to assess the effects of dietary intake of hemp (seeds or cake) on the fatty acid (FA) profile and oxidative stability of eggs. The control diet (C), which was composed of corn, soybean meal and sunflower oil (2.5%), was compared with two experimental diets that were designed to replace sunflower oil with fat from hemp seed (HS diet) or hempseed cake (HC diet). One hundred and twenty Tetra-SL LL laying hens (24-week old) were used in a 10-week trial. Each treatment was replicated five times with eight birds each. Average hen-day egg production was not affected by feeding either the HS or the HC diet. The α-linolenic acid (ALA) concentration in eggs was increased by substituting the HS- or HC-based diets fed to the hens with dietary ALA. Similar deposition profiles were exhibited by eicosapentaenoic acid (EPA) and docosahexaenoic acids (DHA) in yolks in response to increasing the dietary ALA supply. The HS group showed a greater concentration of egg yolk ALA and EPA than the HC group, which had a higher concentration of linoleic acid (LA). These alterations in yolk composition resulted in n−6 : n−3 FA ratio values as low as 2.98 and 4.15 for HS and HC, respectively, compared to 11.07 for the control diet. The atherogenicity index and cholesterol level were not affected by hemp (seed or cake) inclusion, while the thrombogenicity index decreased when compared to the control diet. On days 0, 15 and 30 of storage (4 °C), two eggs were selected randomly from each replicate (totalling 10 eggs per treatment) and analyzed. The PUFAs were not affected by storage. An exception occurred in the HC group, in which eggs had lower n-6 FA content. Egg storage for 30 d led to a reduction in egg α-tocopherol and an increase of malondialdehyde (MDA) concentration, an indicator of lipid peroxidation. The HS treatment resulted in the lowest MDA (0.22 mg MDA/kg yolk for fresh eggs and 0.35 mg for eggs in 30-day storage). The study demonstrates that the level and type of PUFAs, level of α-tocopherol and duration of egg storage significantly affected the oxidative stability of eggs. The results obtained suggest that the inclusion of hemp seed appears to be more effective in maintaining the oxidative stability of egg lipids than hempseed cake. Keywords: egg enrichment, α-tocopherol, malondialdehyde, omega-3, storage time
A spotlight on cross-sectional research: Addressing the issues of confounding and adjustment

ABSTRACT Purpose: This study attempted to conceptualize confounding and guide healthcare management researchers to identify and adjust for potential confounders from the point of view of their theoretical frameworks as a basis of achieving internal validity. Design/methodology/approach: A comprehensive statistical procedure was applied to demonstrate how likely it is for misleading effect sizes to be reached in a cross-sectional healthcare management study as a result of failing to adjust for potential confounders. Participants of the study were 403 volunteer health workers in selected hospitals in Accra, Ghana. A self-reported questionnaire was used to gather data. Confirmatory factor analysis and linear regression analyses were used to present findings. Findings: The study revealed that failing to adjust for potential confounders can over- or under-estimate the ‘ultimate effect’, which was under-estimated in this study by a value of β = . 006. The auxiliary regression estimates (e.g. the variance) were also wrongly estimated owing to failure to adjust for potential confounders. Originality/value: This study is the first of its kind to address the issue of confounding in healthcare management research and justifies how necessary it is for every study to control for all confounding variables.
Drug Withdrawal Effects on Cognition

Considerable neurological evidence indicates that the prefrontal cortex mediates complex decision-making functions, including behavioral autonomy and self-control (Lyvers, 2000). When drugs such as oxycodone are used as pain relievers, they may cause mild cognitive deficits in attention and complex working memory, and episodic memory. Patients who have abused different drugs in the past, have reported to have fatigue and poor concentration. For patients to exhibit withdrawal signs, tolerance or in some cases, addiction must be in play. The current research report highlights these areas and discusses the researched conducted in withdrawal on cognition.
Cognitive Structure, Managers’ Shared Social Understanding: From Psychological and Sociological Concepts to Managerial Strategic Choices

In this paper, the cognitions of industry participants are explored, by analyzing the shared social understanding of the industry (‘mental models’, ‘industry recipes’) as a factor limiting the pursuit of innovative strategies. It is hypothesized that the managers’ interpretation of Porter’s fi ve industry forces, within a given industry, represent the ‘cognitive’ proxy for performance, since shared cognitions represent the (self) imposed performance limitations. The empirical research has been conducted in the Croatian food & beverage industry, where CEOs of mid-sized and large enterprises have been surveyed. Initial support for this hypothesis is provided, since the perceived industry impact (measured by the INDUSTRUCT construct) has been empirically linked to the managers’ strategic behavior pattern. In addition, the discriminant analysis demonstrated that it is possible to forecast the specifi c strategic behavior archetype by analyzing the cognition of the industry’s structure. Implications for both theory and managerial practice are discussed. JEL Classification: L22
LINGUISTIC ALIGNMENT, LEARNER CHARACTERISTICS, AND THE PRODUCTION OF STRANDED PREPOSITIONS IN RELATIVE CLAUSES

Abstract The current study examined the occurrence and benefits of linguistic alignment in two modalities, face-to-face (FTF) and synchronous computer-mediated communication (SCMC), focusing on stranded prepositions in relative clauses. It further examined how learner characteristics (i.e., working memory, language proficiency, previous knowledge of the target structure) mediate the effects of linguistic alignment. Ninety-four Korean students were assigned to one of the following groups: FTF alignment, SCMC alignment, FTF control, and SCMC control. The alignment experimental groups completed two alignment sessions, finished three stranded preposition tests, and carried out a running span test and cloze test over three weeks. Results indicated not only that linguistic alignment occurred in both FTF and SCMC modes but also that alignment was facilitated significantly more in the SCMC than FTF interactions. Furthermore, the findings suggest immediate and delayed learning effects in both modalities, and that learners’ prior knowledge of the target structure was significantly associated with the occurrence of alignment.
Physiological Activation as a Mediator in the Relationship Between Perseverative Cognition and Somatic Symptoms

Somatic symptoms are a significant medical and mental health concern that affects healthy adults and places a significant burden on healthcare systems. The perseverative cognition hypothesis posits that perseverative cognition results in prolonged physiological activation that may be interpreted as somatic symptoms. The purpose of this study was to further examine this hypothesis in a sample of young adults. First, I hypothesized that perseverative cognition would prospectively predict somatic symptoms after controlling for anxiety and depression. Second, I hypothesized that parasympathetic nervous system functioning, measured as respiratory sinus arrhythmia (RSA) and sympathetic nervous system functioning, measured as electrodermal responding (EDR) would mediate this relationship. RSA and EDR were measured before, during, and after a stressor task to provide measures of basal levels, reactivity to the stressor, and recovery from the stressor respectively. These hypotheses were tested in a sample of 220 young adults. Participants ranged from 18 to 39 years old (M = 19.63, SD = 12.10), 84.5% of the participants were female, and 65.5% were Caucasian. Perseverative cognition predicted somatic symptoms in the unexpected direction in both hypothesized models (RSA: β = -0.23, p = 0.001; EDR: β = -0.23, p = 0.074). When anxiety and depression were removed as covariates, somatic symptoms were significantly predicted by perseverative cognition in the expected direction in both models (RSA: β = 0.38, p < 0.001; EDR: β = 0.37, p = 0.003). Neither RSA nor EDR at any time point were significantly related to either perseverative PERSEVERATIVE COGNITION AND SOMATIC SYMPTOMS viii cognition or somatic symptoms, and no indirect effects were observed. Individual mediations revealed that RSA recovery significantly predicted somatic symptoms (β = 0.16; p = 0.029) such that individuals whose parasympathetic nervous system re-engaged following the stressor experienced a higher level of somatic symptoms. Additionally, individuals who reported higher levels of perseverative cognition experienced greater increases in EDR during the stressor task (β = 0.17; p = 0.041). Overall, the findings of this study suggest that perseverative cognition is related to sympathetic nervous system functioning, while parasympathetic nervous system functioning is related to reporting of somatic symptoms. Future research directions and clinical implications are discussed. PERSEVERATIVE COGNITION AND SOMATIC SYMPTOMS 1
The CM carbonaceous chondrite regolith Diepenveen

A carbonaceous chondrite was recovered immediately after the fall near the village of Diepenveen in the Netherlands on October 27, 1873, but came to light only in 2012. Analysis of sodium and poly‐aromatic hydrocarbon content suggests little contamination from handling. Diepenveen is a regolith breccia with an overall petrology consistent with a CM classification. Unlike most other CM chondrites, the bulk oxygen isotopes are extremely 16O rich, apparently dominated by the signature of anhydrous minerals, distributed on a steep slope pointing to the domain of intrinsic CM water. A small subset plots closer to the normal CM regime, on a parallel line 2 ‰ lower in δ17O. Different lithologies in Diepenveen experienced varying levels of aqueous alteration processing, being less aqueously altered at places rather than more heated. The presence of an agglutinate grain and the properties of methanol‐soluble organic compounds point to active impact processing of some of the clasts. Diepenveen belongs to a CM clan with ~5 Ma CRE age, longer than most other CM chondrites, and has a relatively young K‐Ar resetting age of ~1.5 Ga. As a CM chondrite, Diepenveen may be representative of samples soon to be returned from the surface of asteroid (162173) Ryugu by the Hayabusa2 spacecraft.

A study of the effect of the combined application of a physiotherapeutical program with therapeutic fit balls in cases of chronic pain in the lumbar area.

Objective: To investigate the efficiency of the combined application of a physiotherapeutical program with fit-ball exercises in cases of chronic pain in the lumbar area. Subjects and method: 38 out-patients aged 39 to 67, with chronic pain in the lumbar area (dating back from 5-7 years, with last exacerbation 5-6 weeks prior to the patients? inclusion in the study), participated in the study. The patients were divided into two groups-a test group in whose physiotherapy program fit-ball exercises were included, and a control group performing standard analytical exercise routines. The pain was reported in the Visual Analogue Scale of Pain Intensity (VASPI). Muscular testing was performed at the beginning and at the end of the physiotherapy program. The physiotherapy rehabilitation program was implemented once a day during the out-patients? procedures in medical centres, and three time a week-at home. Results and discussion: At the end of the period of monitoring the condition of the patients, changes in the nature of the pain were reported in both groups: with initial levels of VASPI 3.50 for both groups, at the end of the treatment program the level reported by the test group was VASPI 2.00, and VASPI 3.00-by the control group. The continuous physiotherapy program including fit-balls leads to an improvement of the movements and a reduction of the dysfunction in cases of chronic pain in the lumbar area of the spine. The exercise programs using fit-balls performed at home enhance the functional capacity of the lumbar spine.
Realizing spike-timing dependent plasticity learning rule in Pt/Cu:ZnO/Nb:STO memristors for implementing single spike based denoising autoencoder

In this work, the Cu:ZnO based memristors were fabricated and modelled and its biological synaptic characteristics were realized. Phenomenon similar to long-term potentiation and long-term depression were observed in the proposed devices and spike timing dependent plasticity learning rule was established by engineering appropriate input voltage spikes, making the devices suitable for use in artificial neural networks. In order to demonstrate learning mechanism, a denoising autoencoder network was developed by incorporating the synaptic characteristics of the device along with the concept of rank coding. To evaluate the feasibility and performance of the network, images from the MNIST database for handwritten digits were employed. The training of the proposed network was accomplished by incorporating noisy images, and it was validated with images corrupted with Gaussian, Salt & Pepper and Speckle noises. Surprisingly, the obtained results demonstrated that the shape of the digits was recovered to a great extent and almost all noise in the background were removed. The accuracy of the denoising was found to be more than 90% for most cases. The proposed network shows the efficacy of ferroelectric Cu:ZnO memristors as artificial synapses in spiking neural networks, which opens up a new path towards developing future generation biologically compatible neuromorphic systems.
Influences of Product Involvement and Symbolic Consumption Cues in Advertisements on Consumer Attitudes

Symbolic consumption has become pervasive in daily life; advertisements focusing on brand awareness and celebrity endorsements involve strong product symbols and serve as a persuasive advertising tool. This study employed a 2 × 2 between-subject experimental design to investigate the influence of two independent variables, namely the level of consumer product involvement (high and low levels of involvement) and types of symbolic cues (brand and celebrity symbols), on consumer attitudes toward advertisements (Aad) and brands (Ab). Four notable findings were revealed: (1) the level of participant product involvement affected their fondness for Aad and Ab; (2) symbolic cues affected participant Aad and Ab; (3) participants with a high level of product involvement exhibited more positive Aad; and (4) participants with low product involvement demonstrated more positive Ab. In the contemporary advertising market, how enterprises can enable a product to convey a certain symbolic meaning has become particularly critical, and enterprises should not ignore the influences that symbolic consumption may have on consumers. These study results serve as a reference for enterprises and advising agents for devising future product advertising strategies.
Weldability and Lamellar Tearing Susceptibility of High-Strength SN 490C Steel Plates

In this study, weldability and cracking susceptibility of SN 490C steel were firstly investigated. For this study, SN 490C thick plates which had been developed for anti-seismic steel of building structures were welded by flux-cored arc welding (FCAW) and submerged arc welding (SAW) processes based on welding conditions of actual construction site. Weldments using the plates with different thickness were produced using E71T-1C and EH14 filler wires, respectively. For the weldability tests, various welded joints such as butt and T-joints were examined. After welding, microstructure analysis was performed. Various microstructures were found depending on the location of the weldments. Heat effects by multi-pass welding were correlated with the microstructure. The microstructure was correlated with the hardness profile and the impact test result. In addition, the through-thickness tensile test, window test, and Cranfield test were conducted to evaluate sensitivity of lamellar tearing, which may occur during tensile restraint stress of welds. As a result of the tests, it was found that the SN 490C steel was sufficiently resistant to lamellar tearing.
