Comparison between physical properties of ring-spun yarn and compact yarns spun from different pneumatic compacting systems

A comparative study pertaining to physical and mechanical properties of ring-spun yarn vis-a-vis compact yarns spun using three different compacting systems has been reported. Rieter (K-44), Toyota (RX-240) and Suessen (Fiomax) spinning machines have been used and the condensing process of the fibres in the yarn cross-section as per these compact spinning systems is accomplished pneumatically. Thus, a yarn of linear density 5.9 tex (100 Ne) is spun on the spinning systems using Egyptian cotton of the type Giza 86. One way Anova together with least significant difference are employed to feature the means of the properties of spun yarns and a significant difference among them is observed. According to the performed statistical analysis, there is a significant difference between ring - spun yarn properties and each of the pnuematic compact spun yarns. These compact-spun yarns are also found to differ significantly in terms of their physical and mechanical properties; however, they are all found superior to the ring-spun yarn.
The Statistical Characteristics of Small‐Scale Ionospheric Irregularities Observed in the Martian Ionosphere

Small‐scale ionospheric irregularities in magnetic field strength and ionospheric density have recently been discovered at Mars by the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. Studying these irregularities provides insight into the interaction between the thermosphere and ionosphere and allows for comparative aeronomy between Mars, Earth, and other planets. This paper reports the first statistical study utilizing 3.5 years of MAVEN in situ measurements to characterize these irregularities and to provide maps of where these irregularities are most likely to be observed. Irregularities are most likely to be observed at dawn and dusk, between solar zenith angles of 90° and 150°, although events are observed all the way to midnight. Irregularities occur primarily outside of the crustal magnetic field regions, between altitudes of ∼130 and 160 km, when ionospheric dynamo conditions exist (magnetized electrons and unmagnetized ions). The irregularities appear to be MHD‐like in nature (an interesting difference to their electrostatic terrestrial counterparts), characterized by variations in absolute magnetic field strength of 5–15% of the background field and perpendicular to magnetic field length scales of 5–20 km. Although MAVEN cannot accurately resolve the associated density variations, we estimate these variations to typically be between 10% and 75% of the background ionospheric density. When present, irregularity events appear to occur with equal likelihood above and below the ionospheric peak. At Earth, the occurrence of irregularity events exhibits strong seasonal dependencies; the MAVEN data set is currently too small to identify any conclusive trends as a function of Mars season.
Spatial and Social Mobility

This paper analyzes the relationship between spatial mobility and social mobility. It develops a two-skill-type spatial equilibrium model of two regions with location preferences where each region consists of an urban area which is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that both segregation and regional income inequality are negatively correlated with relative regional social mobility. In the model, segregation is driven by differences between urban and residential areas in commuting cost differences between high-skilled and low-skilled workers, whereas regional income inequality also depends on the magnitude of the productivity gap of low-skilled relative to high-skilled workers. A larger productivity gap does not affect segregation, but causes higher income inequality and lower relative mobility in the respective region.
The Option and Decision to Repurchase Stock: The Option and Decision to Repurchase Stock

Open market repurchase programs provide firms with the flexibility to manage the cash and risk aspects of their operations. This paper therefore aims to determine whether cash and risk matter only at the implementation stage in the sequence of a repurchase program: announcement, implementation, and withdrawal. We do find that temporary cash and risk measures only affect the implementation decision, while partially negating the traditional signaling effect around program announcement. The relevance of the flexibility afforded by the early announcement of a repurchase program is also evidenced by a steadily increasing time-to-event probability of repurchase implementation and program withdrawal.
Reproductive properties of the chub Squalius squalus (Bonaparte, 1837) in the Assino Creek (Umbria, Italy)

This study investigated the reproductive properties of the population of chub Squalius squalus (Linnaeus, 1758) in the Assino creek, one of the largest tributaries of the upper course of the River Tiber. A total of 547 specimens were caught monthly from March 2008 to May 2009. The age composition of the sample ranged between 0+ and 11+. The sample was made up of 64.54% males and 35.46% females; sexual maturity was attained in both sexes in the second year of life. Analysis of the gonado-somatic index (GSI) and of the stage of gonad maturation throughout the year suggests that the reproductive period of the population extends over a long time (April–July). The relationship between total length and fecundity was F = 5.466TL2. 312 . The mean number (±SE) of eggs produced by each female was 15 351 ± 1705 and increased with the size and age of the specimens; with regard to relative fecundity, an average value (±SE) of 53 553 ± 4098 eggs·kg-1 was observed. The mean diameter (±SE) of ripe eggs was 0.117 ± 0.004 cm. This study sheds light on some important characteristics of the reproductive biology of the chub that have not been fully investigated in Italian populations.
Analysing cyclist behaviour at cycling facility discontinuities using video data

The primary purpose of any transportation network is to provide connectivity between the origin and travel destination. However, given the vehicle oriented structure of the road network in many countries, there are connectivity issues in the cycling network, which has been implemented later. Discontinuities are physical interruptions in the cycling network where cyclists are faced with unexpected situations such as the end of a cycling facility or the change from one facility type to another that are perceived as inconvenient and less safe. The microscopic behaviour of cyclists and the risks they face at these points of discontinuity has not been extensively investigated in the literature. This study aims to evaluate the challenges faced by cyclists at discontinuities by observing cyclist behaviour at these locations and comparing them to control sites using automated video analysis techniques. Our methodology allows the extraction of valuable microscopic data for evaluation of cyclist behaviour at any location. The methodology is applied to a case study of four sites in Montreal, Canada. Using a set of discontinuity measures proposed in a previous work and applied to Montreal's cycling network, video data was collected from a pole-mounted camera at locations with discontinuity and control sites. After extracting road user trajectories from the video data, a trajectory clustering algorithm was applied to find cyclists' motion patterns and the various maneuver strategies adopted by cyclists. Speeds and acceleration statistics are extracted and compared between different motion patterns and between discontinuity and control sites. Results show that cyclists undertake a larger number of maneuvers at points of discontinuity compared to their control sites, and that both cyclist accelerations and speeds exhibit larger variations at discontinuities compared to larger and more stable speeds at control sites.
Severe androgenetic alopecia as a maker of metabolic syndrome in male patients of androgenetic alopecia: a hospital based case control study

Background: Several previous studies have investigated the association between androgenetic alopecia (AGA) and metabolic syndrome (MS), with inconsistent results. Objectives of the study were to study the prevalence of metabolic syndrome in male patients of androgenetic alopecia and compare with control population and study the relationship of metabolic syndrome with different grades of AGA. Methods: This prospective hospital based case control study included 100 new clinically diagnosed males of androgenetic alopecia, and age and sex matched control group. Assessment for presence of various components of metabolic syndrome was done following a uniform protocol in cases and controls. AGA was classified as per Hamilton –Narwood classification, grade I to III was classified as mild –moderate and grade IV and higher as severe AGA. Results: Of the 100 male AGA patients (age range 21-50, mean 34.49), 36 had grade II AGA, 24 had grade III AGA, 20 had grade IV AGA, 15 had grade V AGA and 5 had grade VI AGA. Among AGA patients, 60 of patients had mild-moderate AGA and 40 patients had severe AGA. Metabolic syndrome was statistically significantly more common in patients with AGA compared to controls. Among patients of AGA, metabolic syndrome was statistically significantly present in severe AGA compared to mild-moderate AGA. Among the evaluated parameters, like blood pressure, fasting blood sugar, dyslipedemia, abdominal obesity, all were significantly more common in AGA patients compared to controls except abdominal obesity. Conclusions: In the present study, metabolic syndrome was found to be 4.6 times more common in patients of androgenetic alopecia as compared to controls, being statistically significant, and more common in those with severe grades. This suggests that androgenetic alopecia patients especially with severe grades are at risk of metabolic syndrome and other cardiovascular diseases.
Rapid Naming: The Importance of Different Reading and Spelling Dimensions

This research extends the empirical evidence regarding the influence of rapid naming on the acquisition of reading and spelling of European Portuguese in third and fourth grade children. In reading, it addresses different dimensions (accuracy and fluency) and materials (words, pseudowords, and text) and it controls the influence of phonological awareness. In spelling, it addresses the accuracy and the fluency in the codification of words and pseudowords and it controls the influence of phonological awareness and handwriting fluency. In reading, rapid naming explained higher variance percentages in fluency than in accuracy. The main effect was registered on text reading fluency by a RAN digit test. In spelling, rapid naming predicted a small, but significant, percentage of word spelling fluency.
Marine and terrestrial palynofloras from transitional Devonian-Mississippian strata, Illinois Basin, U.S.A.

Diverse and reasonably well preserved palynoforal assemblages are described from a 12.9 m-thick section of the Upper Devonian Saverton Shale and a 17.0 m-thick section of the Lower Mississippian Hannibal Shale exposed along a bluff at Atlas South, Pike County, Illinois, U.S.A. The microphytoplankton assemblage, consisting of acritarchs and prasinophytes, comprises 17 genera and 38 species, including two new species (Cymatiosphaera scitula and Gorgonisphaeridium savertonense) and one new combination (Puteoscortum sprucegrovense). The miospore assemblage contains 14 species - one new (Punctatisporites hannibalensis) and one new combination (Vallatisporites hystricosus) - distributed among 13 genera. The overwhelming majority of microphytoplankton and miospore taxa occur in the Saverton Shale. The Saverton microphytoplank-ton assemblage indicates a latest Devonian (Strunian) age and is most similar in composition to previously described Late Devonian assemblages from North America and China. There is a low to moderate degree of similarity between the Saverton microphytoplankton assemblage and those reported elsewhere in the world. The miospore assemblage further corroborates a latest Devonian age (LN miospore Zone), as signifed by its content of Retispora lepidophyta, Verrucosisporites nitidus, Indotriradites explanatus, and Vallatisporites hystricosus. Based on the significant drop in diversity of the microphytoplankton, the presence of morphologically simple morphotypes, and several taxa, whose range extends into the Early Mississippian, a Kinderhookian date for the Hannibal Shale is reasonable. The Hannibal miospore palynofora is even more impoverished than the associated microphytoplankton, and its few named taxa are consonant with, albeit not independently corroborative of, an Early Mississippian age. Sedimentologic and paleontologic-palynologic evidence indicates that the Saverton and Hannibal shales were both deposited in a low energy, somewhat offshore, normal marine environment within the Illinois Basin.

Aqua Drugs and Chemicals Used in Aquaculture in Jamalpur Sadar Upazila of Bangladesh

The present study was conducted to know the present status of use of commercial aqua drugs and chemicals and their impact on fish health management in Jamalpur sadar upazila (sub-district). A questionnaire survey was conducted for a period of seven months from December 2013 to June 2014 from nineteen small scale fish farms, seven commercial fish farms, eight fish hatcheries and seven chemical retailers. Five categories of aqua drugs and chemicals were identified and noted in the study area. Those drugs and chemicals were produced by the following seven pharmaceutical companies: Square Pharmaceuticals Ltd., Novarties Animal Health, ACI Animal Health, Fish Tech BD Ltd., Acme Laboratories, Reneta, and Eon Animal Health. Different types of diseases such as edwardsiellosis, EUS (epizotic ulcerative syndrome), red spot and different parasitic diseases were found to occur in pangus (Pangasius hypophthalmus), tilapia (Oreochromis nilotica), sharputi (Puntius sarana), rui (Labeo rohita), mrigal (Cirrhinus mrigala), Thai koi (Anabas testudineus), shing (Heteropneustes fossilis) and silver carp (Hypophthalmicthys molitrix). Geotox, JV Zeolite, Aquakleen and Biomin Aquaboost were used for water quality management; Oxyflow, Bio Care and Oxylife to improve dissolve oxygen level; Megavit Aqua, Aqua Boost, Aquamin, Acimix Super-fish, Square Aquamix and Vitax-C as growth promoter; Oxysentin 20%, Captor, Aquamycine and Renamycin soluble powder as antibiotics; Hepaprotect-Aqua, Timsen, Virex, Polgard Plus as disinfectant; lime, salt, formalin, potash and malachite green were used against fish diseases. Susceptible months of disease outbreak in the study area were November to February. The recovery of fish diseases was found from 50% to 95% in Jamalpur region. Farmers’ poor understandings about the application of aqua drugs and proper withdrawal period were found in the study area which might have adverse effect on fish and human health. Proper training of fish farming community about the appropriate dose and administration methods should be suggested for safe and sustainable aquaculture practices.
The time trend in the matching function

"We revisit the puzzling finding that labour market performance appears to deteriorate, as suggested by negative time trends in empirical matching functions. We investigate whether these trends simply arise from omitted variable bias. Concretely, we consider the omission of job seekers beyond the unemployed, the omission of inflows as opposed to stocks, and the failure to account for vacancy dynamics. We first build a model of all labour market flows and use it to construct series for these flows from aggregate data on the U.S. labour market. Using these series, we obtain a measure for employed and non-participating job seekers. When we thus include all job seekers, the estimated time trend remains unchanged. We similarly obtain measures for inflows into unemployment and vacancies. When these are included, the magnitude of the time trend is halved but remains significant. When we account for basic vacancy dynamics, the estimated time trend can be fully explained by omitted variable bias. As suggested by this result, we present evidence that empirical matching functions can be interpreted as versions of the law of motion for vacancies: the coefficients in matching functions coincide with the coefficients in the law of motion after correcting for omitted variable bias.

Effects of Job Stress, Coping, and Type a Behavior Among Recently-Graduated Nurses.

A model integrating elements of job stress theory, coping theory, and Type A behavior research was developed and tested in the present study. The model was employed to generate numerous hypotheses concerning proposed relations among job stresses, coping strategies, Type A behavior, and stress-related outcomes. These hypotheses were tested utilizing questionnaire data collected from 136 recently-graduated nurses in ten hospitals. As predicted, Type A behavior was positively associated with job stresses, both Type A and job stresses were related to felt strain and organizational commitment, and commitment inversely predicted turnover intention. Hypotheses concerning the proposed moderating effect of coping on the stress-strain and stress-commitment relations were not supported. Because both the role of coping and some relations among other variables in this model remained unclear, a revised model was proposed and tested post hoc using path analysis. The results of the path analysis suggested that: (a) Type A behavior was a determinant of job stresses and felt strain, (b) coping behavior affected nurses' feelings of strain, (c) strain influenced nurses' organizational commitment, and (d) commitment affected turnover intention. Overall, the results indicated that Type A behavior and job stress can adversely affect a nurse's adaptation to a new job, and suggested the importance of developing programs to help new nurses adapt to their jobs. The results also pointed to the need for continued examination of the process and outcomes of coping with job stress. Effects of Job Stress, Coping, and Type A Behavior Among Recently-Graduated Nurses The present research examines both the relations among and results of job stress, Type A behavior, and coping behavior in a sample of recently-graduated nurses. Accordingly, a model of the process by which job stress, Type A behavior, and coping affect personal and organizational outcomes will be presented. The proposed model represents an integration of previous job stress and coping models and research findings, both those general in focus and those specific to the field of nursing. Although existing models and findings will be reviewed, the expansiveness of the stress and coping literature necessarily limits the presentation of these theoretical and empirical works to those concepts that substantially contributed to the proposed model.
Workplace interventions for intimate partner violence: A systematic review

Abstract Workplace interventions represent important opportunities to increase awareness of and adherence to disease prevention and health promotion initiatives. However, research on workplace interventions for intimate partner violence (IPV) has not been systematically evaluated. This systematic review summarizes existing studies evaluating workplace interventions for IPV. PubMed, PsycINFO, Business Source Complete, Web of Science, and Social Services Abstracts were systematically searched for English-language studies published before November 2017. Six studies evaluating five interventions were included. Only one study used a randomized design, and only two studies measured whether outcomes were sustained over time. None of the interventions addressed perpetrators of IPV. Interventions focused on recognizing signs of abuse, responding to victims, and providing referrals to community-based resources. Methodological rigor of included studies varied, but all reported at least one intervention-related benefit. Findings included improved awareness of IPV, increased provision of information to victims, and greater willingness to intervene if an employee may be experiencing IPV. Although sparse, available evidence suggests there are potential benefits of workplace interventions for IPV. It is important for future interventions to focus on primary and secondary prevention of IPV and address perpetration, and for investigators to use rigorous study designs and measure whether effects are sustained.
“They can crush you”: Nursing students’ experiences of bullying and the role of faculty

This paper will explore the faculty role when nursing students experience bullying, and what teaching practices best support student confidence and learning. Failure to address the issue of bullying in nursing education contributes to bullying in the profession, and creates an atmosphere of distrust between students and faculty. Nursing students have reported that faculty sometimes behave in bullying ways or are ill-prepared to address bullying as it occurs. Faculty may contribute to bullying unknowingly, as students may perceive teaching behaviours, such as giving feedback, as bullying. Giving feedback is a skill in itself, and faculty members should consider factors influencing a student’s perception of student/teacher interactions. Having a firm grasp on conflict resolution processes and reviewing related curriculum are responsibilities of post-secondary nurse educators. Faculty also have the responsibility to recognize and address conflict in a timely manner, and turn difficult situations into learning experiences or teachable moments. In order to prevent faculty bullying of students, faculty members should acknowledge the inherent vulnerability of learners, and also reflect on their own communication practices and their potential impact on learners.
