Evaluating Ballast Stabilization during Initial Compaction Phase
Authors: Liu Shushu , Huang Hai , Qiu Tong
Published: February 2018

The railroad ballast initial compaction phase occurs immediately after the construction or maintenance of a track is finished. The ballast particles are densified into a more compact state after certain load repetitions. With increases in heavy haul trains, the heavy loads imposed on the track significantly change the ballast behavior. In order to investigate the ballast particle movement in different track conditions, this paper presents a series of ballast box tests. Three types of tests were conducted as follows: one with an unstabilized track section, one with a track section geogrid-stabilized at a depth of 30 cm, and another one with a track section geogrid-stabilized at a depth of 40 cm. The track section consists of two half-crossties, a rail, ballast, subballast, and subgrade. Four wireless devices, “SmartRocks,” were installed underneath the rail seat and underneath the shoulder at a depth of 30 cm and 40 cm, respectively, to monitor the ballast particle movement under cyclic loading. The ballast behavior in different sections is compared and discussed in this paper.
Neuronal Organization in the Inferior Colliculus Revisited with Cell-Type-Dependent Monosynaptic Tracing
Authors: Chen Chenggang , Cheng Mingxiu , Ito Tetsufumi , Song Sen
Published: February 2018

The inferior colliculus (IC) is a critical integration center in the auditory pathway. However, because the inputs to the IC have typically been studied by the use of conventional anterograde and retrograde tracers, the neuronal organization and cell-type-specific connections in the IC are poorly understood. Here, we used monosynaptic rabies tracing andin situhybridization combined with excitatory and inhibitory Cre transgenic mouse lines of both sexes to characterize the brainwide and cell-type-specific inputs to specific neuron types within the lemniscal IC core and nonlemniscal IC shell. We observed that both excitatory and inhibitory neurons of the IC shell predominantly received ascending inputs rather than descending or core inputs. Correlation and clustering analyses revealed two groups of excitatory neurons in the shell: one received inputs from a combination of ascending nuclei, and the other received inputs from a combination of descending nuclei, neuromodulatory nuclei, and the contralateral IC. In contrast, inhibitory neurons in the core received inputs from the same combination of all nuclei. After normalizing the extrinsic inputs, we found that core inhibitory neurons received a higher proportion of inhibitory inputs from the ventral nucleus of the lateral lemniscus than excitatory neurons. Furthermore, the inhibitory neurons preferentially received inhibitory inputs from the contralateral IC shell. Because IC inhibitory neurons innervate the thalamus and contralateral IC, the inhibitory inputs we uncovered here suggest two long-range disinhibitory circuits. In summary, we found: (1) dominant ascending inputs to the shell, (2) two subpopulations of shell excitatory neurons, and (3) two disinhibitory circuits.

SIGNIFICANCE STATEMENTSound undergoes extensive processing in the brainstem. The inferior colliculus (IC) core is classically viewed as the integration center for ascending auditory information, whereas the IC shell integrates descending feedback information. Here, we demonstrate that ascending inputs predominated in the IC shell but appeared to be separated from the descending inputs. The presence of inhibitory projection neurons is a unique feature of the auditory ascending pathways, but the connections of these neurons are poorly understood. Interestingly, we also found that inhibitory neurons in the IC core and shell preferentially received inhibitory inputs from ascending nuclei and contralateral IC, respectively. Therefore, our results suggest a bipartite domain in the IC shell and disinhibitory circuits in the IC.
Heteromeric KV2/KV8.2 Channels Mediate Delayed Rectifier Potassium Currents in Primate Photoreceptors
Authors: Gayet-Primo Jacqueline , Yaeger Daniel B. , Khanjian Roupen A. , Puthussery Teresa
Published: February 2018

Silent voltage-gated potassium channel subunits (KVS) interact selectively with members of the KV2 channel family to modify their functional properties. The localization and functional roles of these silent subunits remain poorly understood. Mutations in the KVS subunit, KV8.2 (KCNV2), lead to severe visual impairment in humans, but the basis of these deficits remains unclear. Here, we examined the localization, native interactions, and functional properties of KV8.2-containing channels in mouse, macaque, and human photoreceptors of either sex. In human retina, KV8.2 colocalized with KV2.1 and KV2.2 in cone inner segments and with KV2.1 in rod inner segments. KV2.1 and KV2.2 could be coimmunoprecipitated with KV8.2 in retinal lysates indicating that these subunits likely interact directly. Retinal KV2.1 was less phosphorylated than cortical KV2.1, a difference expected to alter the biophysical properties of these channels. Using voltage-clamp recordings and pharmacology, we provide functional evidence for Kv2-containing channels in primate rods and cones. We propose that the presence of KV8.2, and low levels of KV2.1 phosphorylation shift the activation range of KV2 channels to align with the operating range of rod and cone photoreceptors. Our data indicate a role for KV2/KV8.2 channels in human photoreceptor function and suggest that the visual deficits in patients withKCNV2mutations arise from inadequate resting activation of KVchannels in rod and cone inner segments.

SIGNIFICANCE STATEMENTMutations in a voltage-gated potassium channel subunit, KV8.2, underlie a blinding inherited photoreceptor dystrophy, indicating an important role for these channels in human vision. Here, we have defined the localization and subunit interactions of KV8.2 channels in primate photoreceptors. We show that the KV8.2 subunit interacts with different Kv2 channels in rods and cones, giving rise to potassium currents with distinct functional properties. Our results provide a molecular basis for retinal dysfunction in patients with mutations in theKCNV2gene encoding KV8.2.
Differential Synaptic Remodeling by Dopamine in Direct and Indirect Striatal Projection Neurons in Pitx3−/−Mice, a Genetic Model of Parkinson's Disease
Authors: Suarez Luz M. , Alberquilla Samuel , García-Montes Jose R. , Moratalla Rosario
Published: February 2018

In toxin-based models of Parkinson's disease (PD), striatal projection neurons (SPNs) exhibit dendritic atrophy and spine loss concurrent with an increase in excitability. Chronicl-DOPA treatment that induces dyskinesia selectively restores spine density and excitability in indirect pathway SPNs (iSPNs), whereas spine loss and hyperexcitability persist in direct pathway SPNs (dSPNs). These alterations have only been characterized in toxin-based models of PD, raising the possibility that they are an artifact of exposure to the toxin, which may engage compensatory mechanisms independent of the PD-like pathology or due to the loss of dopaminergic afferents. To test all these, we studied the synaptic remodeling in Pitx3−/−or aphakia mice, a genetic model of PD, in which most of the dopamine neurons in the substantia nigra fail to fully differentiate and to innervate the striatum. We made 3D reconstructions of the dendritic arbor and measured excitability in identified SPNs located in dorsal striatum of BAC-Pitx3−/−mice treated with saline orl-DOPA. Both dSPNs and iSPNs from BAC-Pitx3−/−mice had shorter dendritic trees, lower spine density, and more action potentials than their counterparts from WT mice. Chronicl-DOPA treatment restored spine density and firing rate in iSPNs. By contrast, in dSPNs, spine loss and hyperexcitability persisted followingl-DOPA treatment, which is similar to what happens in 6-OHDA WT mice. This indicates that dopamine-mediated synaptic remodeling and plasticity is independent of dopamine innervation during SPN development and that Pitx3−/−mice are a good model because they develop the same pathology described in the toxins-based models and in human postmortem studies of advanced PD.

SIGNIFICANCE STATEMENTAs the only genetic model of Parkinson's disease (PD) that develops dyskinesia, Pitx3−/−mice reproduce the behavioral effects seen in humans and are a good system for studying dopamine-induced synaptic remodeling. The studies we present here establish that the structural and functional synaptic plasticity that occur in striatal projection neurons in PD and inl-DOPA-induced dyskinesia are specifically due to modulation of the neurotransmitter dopamine and are not artifacts of the use of chemical toxins in PD models. In addition, our findings provide evidence that synaptic plasticity in the Pitx3−/−mouse is similar to that seen in toxin models despite its lack of dopaminergic innervation of the striatum during development. Pitx3−/−mice reproduced the alterations described in patients with advanced PD and in well accepted toxin-based models of PD and dyskinesia. These results further consolidate the fidelity of the Pitx3−/−mouse as a PD model in which to study the morphological and physiological remodeling of striatal projection neurons by administration ofl-DOPA and other drugs.
Individual Importance Weighting of Domain Satisfaction Ratings does Not Increase Validity
Authors: Rohrer Julia M. , Schmukle Stefan C.
Published: February 2018

Bottom-up models of life satisfaction are based on the assumption that individuals judge the overall quality of their lives by aggregating information across various life domains, such as health, family, and income. This aggregation supposedly involves a weighting procedure because individuals care about different parts of their lives to varying degrees. Thus, composite measures of well-being should be more accurate if domain satisfaction scores are weighted by the importance that respondents assign to the respective domains. Previous studies have arrived at mixed conclusions about whether such a procedure actually works. In the present study, importance weighting was investigated in the Panel Study of Income Dynamics (PSID; N = 5,049). Both weighted composite scores and moderated regression analyses converged in producing the conclusion that individual importance weights did not result in higher correlations with the outcome variable, a global measure of life satisfaction. By contrast, using weights that vary normatively across domains (e.g., assigning a larger weight to family satisfaction than to housing satisfaction for all respondents) significantly increased the correlation with global life satisfaction (although incremental validity was rather humble). These results converge with findings from other fields such as self-concept research, where evidence for individual importance weighting seems elusive as best.

Published: February 2018

Regional history museums are uniquely positioned to cultivate a sense of place for their visitors and are often called upon to steward thoughtful community dialogues. These duties are particularly important when a community is struggling to reconcile its past as it confronts contemporary issues. This essay explores Levine Museum of the New South’s K(NO)W Justice K(NO)W Peace initiative—a rapid-response exhibit and related programming cocreated with community members in the aftermath of the police-involved shooting of Keith Lamont Scott and the protest that unfolded in Charlotte, North Carolina, in September 2016. This essay interrogates the approaches, processes, and lessons learned as the Levine Museum sought to spark civil dialogue and understanding at a time when its community needed it most.
Prevalence of Obesity and Severe Obesity in US Children, 1999–2016
Authors: Skinner Asheley Cockrell , Ravanbakht Sophie N. , Skelton Joseph A. , Perrin Eliana M. , Armstrong Sarah C.
Published: February 2018

OBJECTIVES:

To provide updated prevalence data on obesity trends among US children and adolescents aged 2 to 19 years from a nationally representative sample.

METHODS:

We used the NHANES for years 1999 to 2016. Weight status was determined by using measured height and weight from the physical examination component of the NHANES to calculate age- and sex-specific BMI. We report the prevalence estimates of overweight and obesity (class I, class II, and class III) by 2-year NHANES cycles and compared cycles by using adjusted Wald tests and linear trends by using ordinary least squares regression.

RESULTS:

White and Asian American children have significantly lower rates of obesity than African American children, Hispanic children, or children of other races. We report a positive linear trend for all definitions of overweight and obesity among children 2–19 years old, most prominently among adolescents. Children aged 2 to 5 years showed a sharp increase in obesity prevalence from 2015 to 2016 compared with the previous cycle.

CONCLUSIONS:

Despite previous reports that obesity in children and adolescents has remained stable or decreased in recent years, we found no evidence of a decline in obesity prevalence at any age. In contrast, we report a significant increase in severe obesity among children aged 2 to 5 years since the 2013–2014 cycle, a trend that continued upward for many subgroups.

OBJECTIVES:

To update clinical practice guidelines to assist primary care (PC) clinicians in the management of adolescent depression. This part of the updated guidelines is used to address practice preparation, identification, assessment, and initial management of adolescent depression in PC settings.

METHODS:

By using a combination of evidence- and consensus-based methodologies, guidelines were developed by an expert steering committee in 2 phases as informed by (1) current scientific evidence (published and unpublished) and (2) draft revision and iteration among the steering committee, which included experts, clinicians, and youth and families with lived experience.

RESULTS:

Guidelines were updated for youth aged 10 to 21 years and correspond to initial phases of adolescent depression management in PC, including the identification of at-risk youth, assessment and diagnosis, and initial management. The strength of each recommendation and its evidence base are summarized. The practice preparation, identification, assessment, and initial management section of the guidelines include recommendations for (1) the preparation of the PC practice for improved care of adolescents with depression; (2) annual universal screening of youth 12 and over at health maintenance visits; (3) the identification of depression in youth who are at high risk; (4) systematic assessment procedures by using reliable depression scales, patient and caregiver interviews, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria; (5) patient and family psychoeducation; (6) the establishment of relevant links in the community, and (7) the establishment of a safety plan.

CONCLUSIONS:

This part of the guidelines is intended to assist PC clinicians in the identification and initial management of adolescents with depression in an era of great clinical need and shortage of mental health specialists, but they cannot replace clinical judgment; these guidelines are not meant to be the sole source of guidance for depression management in adolescents. Additional research that addresses the identification and initial management of youth with depression in PC is needed, including empirical testing of these guidelines.

AbstractThe aim of the paper was to determine metric characteristics of the coordination and precision test named “ball-foot-wall” (Bös, 2001 according to Crnokić, 2011) on a sample of early and pre-school education students. The study sample consisted of 25 students first and second year of the Faculty of teacher education in Petrinja. Next to descriptive statistics, normality of distribution was tested, coefficients of reliability and the average correlation between the particles. Factor structure was checked with component analysis. The results showed satisfactory values of reliability coefficients. The isolated factor “covered up” 72.19% of the total value of the correlation matrix and indicates the existence of a common object of measurement, in this case, motoric skills coordination and precision. Although, the test was intended for use with children, age 6-11, to verify Universal sports school participants’ skills (Bös, 2001 according to Crnokić, 2011) its use with elderly participants showed good metric characteristics and can be used in practice with this age group of students. Given to the small number of participants in the study for further determination of metric characteristics of this test it is recommended significantly larger sample.Key words: motor skills, female students, early and pre-school education---SažetakCilj rada je utvrditi metrijske karakteristike testa koordinacije i preciznosti ,,Lopta – noga – zid“ na uzorku studentica ranog i predškolskog odgoja i obrazovanja.

Video demonstration as way of teaching in education
Authors: Vrbik Ivan , Vrbik Andrea
Published: February 2018

The advancement of technology and its easy access contributed to the everyday use of different technical aids in all aspects of human society as an essential asset for work. In the area of education, especially within physical exercising, for information transfer and familiarizing with the new task at hand, the most common way of introducing a new task is live demonstration.  A video demonstration is especially interesting as a mean of transferring information. Model learning cannot be considered as a simple imitation within specific area of motor behavior, hence it is a process in which a subject observes the model behavior and adjusts it to his/her's performance as a result of an interaction (Horn i Williams, 2004). It is an effective method used for learning simple and complex motor tasks, and observational practice if used with physical performance of the task significantly contributes to the learning of observed skills (Wulf, Shea i Lewthwaite, 2010). An expert video demonstration or direct demonstration is the most common way of giving instructions while learning motor tasks (Doussoulin i Rehbein, 2011). The use and practical application of expert video demonstration was confirmed in other areas as well. Research of video demonstration effectiveness in learning different skills as well as comparison with other ways of learning were conducted in medical students, nurses, in learning social skills in children with development difficulties, students with emotional problems in behavior, in children aged 12 to 18. The main goal of this paper was a review of literature considering video demonstration as a means of information feedback for facilitated learning of certain motor tasks in particular field of kinesiology.

Published: February 2018

The aim of this study was to determine the relation between physical activity and functional capacity at the primary school pupils. Many people are not aware that the health of the most important in human life and associated with the movement. In recent decades, the number of obese people, children and adolescents is is significantly increasing. The modern life style of children and young people are increasingly missing movement and outdoor games, is prevalent sedentary lifestyle (TV, Internet, Play Station ..) adverse effects the development of abilities and skills of children and their health status. The study included 80 students of the third grade of primary school, of which 43 boys (mean age 9.30 ± 0.46 years) and 37 girls (mean age 9.29 ± 0.47 years). The students attended two elementary schools in the city of Petrinja., First Primary School and Elementary School Dragutin Tadijanović. The survey was conducted in the school year 2014/2015. The sample of variables consisted of anthropometric measures of body height, weight, skin fold of the upper arm, back skinfold, abdominal skinfold. The functional abilities were measured test run for 3 minutes - F3, which is used to assess the level of functional ability in primary education in the Republic of Croatia. The level of physical activity was estimated PAQ-C questionnaire.   From the results it is evident that of the total sample 60% of them have a normal percentage of body fat, while almost 40% of students with excessive fat in the body. The conclusion of this study indicates a high percentage of students who are overweight. Functional capacity was inversely associated with indicators of obesity, which means that students with high levels of functional capacity have a lower percentage of body fat. School age is the best time to stimulate and positive impact on the growth and development of children and the missed possibilities to that age cannot be recovered in later stages of life.  Keywords: aerobic capacity, functional ability, obesity, students, school

Getting to know the knowledge that cultural practices have allows researchers to obtain the greatest benefit from the potential of fodder sources, this knowledge is necessary for animal production success. The aim of this study was to explore the bromatological response of Tripsacum laxum to fertilization with different levels of nitrogen, phosphorus, and potassium that were applied to the ground. The investigation was conducted at the “Alfredo Volio Mata” Experimental Dairy Farm a Dairy farm that is part of the University of Costa Rica and that is located in Ochomogo, Cartago, Costa Rica. In the investigation a randomized block design with four replications and treatments arranged in a factorial central composite and on a rotatable 53 was used. Dry matter, crude protein, neutral detergent fiber, and ether extract were determined. Depending on the levels of fertilization with N, P, and K, the appropriate doses were obtained in order to reach the maximum nutrient contents in each of the bromatological parameters evaluated in this study, it was possible to optimize the composition of the fertilizer mixture based on the nutritional component to be particularly favored, either on the leaf, on the stem, or on the whole plant. No single fertilizer dose was able to improve all nutritional components of the plant.

Terminal drought is a worldwide constraint to common bean production and its negative effects will be increased by climate change. The objective of this research was to characterize phenotypically advanced lines and commercial cultivars of common bean for their resistance to terminal drought stress. Field trials were conducted during 2012 and 2013 at Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia. A 4x4 partially balanced lattice design with four replicates was used and, evaluated under irrigation and terminal drought. To achieve the terminal drought condition, irrigation was suspended at 22-23 days after planting. Terminal drought reduced mean grain yield by 68%. Lines SEN 56, BFS 29, NCB 226 and SER 16 showed high grain yield in both irrigated (3617-3836 kg/ ha) and terminal drought (1232-1447 kg/ha) conditions, while RCB 593 and G 40001 showed high grain yield in drought (>1270 kg/ha) and similar to checks in irrigated condition. The most resistant lines showed lower drought susceptibility index (0,88 - 1,00), earlier maturity (56 - 60 dds), superior geometric mean (1931 - 2311 kg/ha), and higher number of grains/m2, (673 - 1250). Drought resistant lines produced at least 15% and 50% more grain yield than EAP 9510-77, commercial check for Central America, in irrigated and drought condition, respectively. In addition, they were also superior to other commercial checks such as DOR 390 and Bribri.
health enhancement programme for physiotherapy students: A mixed methods pilot study
Authors: Lo Kristin , Francis-Cracknell Alison , Hassed Craig
Published: February 2018

Health professional students have a high incidence of fitness to practise issues, including stress and may need strategies to support their wellbeing. The 331 first year Bachelor of Physiotherapy students enrolled in our programme between 2009 and 2013 undertook a 3–4 week wellness programme. They completed the Perceived Stress Scale (PSS), Fantastic Lifestyle Assessment questionnaire and the World Health Organisation Quality of Life Brief (WHOQOL-BREF) scale before and after the programme. Thematic analysis was used to interpret qualitative data. A non-clinically significant increase in the PSS coincided with increased assessment load during the semester which is a potential confounding variable thus randomised controlled trials taking this into account are indicated. Increases in the Fantastic Lifestyle Assessment across the 4-week programme indicated a healthier lifestyle had been adopted. Participants enjoyed the mindfulness (being aware of the present moment) activities, resources, sharing of discussion, content on healthy behaviours and goal setting. Practical activities in tutorials, and the lecturer and tutorial staff were viewed positively. There were a number of suggested changes to the programme content. To our knowledge this is the first documented wellness programme for physiotherapy students. A number of quantitative studies exist regarding health professional wellness courses, but minimal qualitative data exist. This article aims to address this.
Response of normally consolidated kaolin clay under irregular cyclic loading and comparison with predictions from the accumulation procedure
Authors: Zografou D. , Gourvenec S. , O'Loughlin C. D.
Published: February 2018

The accumulation procedure on contour diagrams of shear strain is used in geotechnical design to account for the effect of cyclic loading on offshore foundations. In this paper, contour diagrams of maximum shear strain are presented based on a series of stress-controlled, symmetrical and non-symmetrical, cyclic direct simple shear tests on normally consolidated kaolin clay that can be used to re-examine the extensive database of model testing in kaolin clay. It is shown that failure under non-symmetrical cyclic loading can be defined at a higher maximum shear strain than under symmetrical loading, offering potential opportunities for reducing foundation sizes for structures that are less sensitive to displacement. Staged tests with parcels of uniform amplitudes have also been performed to compare the measured shear strains with the values predicted by the accumulation procedure. It is shown that the accumulation procedure predicts the strain measured in the symmetrical staged tests well, but over-predicts shear strains measured in the non-symmetrical staged tests.

Gregorio Magno, Rom. 11, 25-26 y la conversión de los judíos en el fin de los tiempos
Authors: Cohen Rodrigo Laham
Published: February 2018

En este artículo se explora la posición de Gregorio Magno en relación a la noción paulina de conversión de los judíos en el fin de los tiempos enunciada en Epístola a los Romanos 11, 25-26. La investigación pone en evidencia que Gregorio sigue el pasaje paulino solo en sus textos con fuerte peso exegético – Moralia, Homiliae in Hiezechihelem y Homiliae in Evangelia – mientras que la temática de la conversión final aparece ausente en el resto de sus obras. Ello se explica si se toma en cuenta que Gregorio refirió – en sus obras exegéticas – a judíos hermenéuticos mientras que en las restantes – entre las que resalta el Registrum epistularum por sus explícitas menciones a comunidades judias – el énfasis estuvo en los judíos históricos.

Do mercado de livros ao acampamento militar: um estudo da difusão da 'Eneida' no Império a partir dos 'exercitationes scribendi'
Authors: Mota Thiago Eustáquio Araújo
Published: February 2018

Segundo a tradição biográfica tardo-antiga, Virgílio expressou antes de morrer o desejo de incinerar os livros da Eneida, uma vez que o trabalho da composição estava incompleto. Até a invenção do códice, o principal meio de divulgação da Eneida era muito provavelmente o volumen constituído por folhas de papiro. Tendo em vista as limitações deste tipo de suporte, é provável que os livros do poema circulassem separadamente. A julgar pelo corpus papirológico (31 papiros identificados até o atual estágio da pesquisa), pela epigrafia e pelas menções esporádicas dos autores latinos, o épico virgiliano alcançou uma rápida difusão nos quadros do Império logo nos dois primeiros séculos de sua publicação (séc. I a.C.). Como parte da tipologia da fonte pertinente à proposta de abordagem histórica do épico, debruçamo-nos neste artigo sobre um recorte da arqueologia do texto anterior aos codices antiquores (séculos IV-V). Nossa abordagem considera a problemática do suporte do volumen e a difusão dos poemas virgilianos, tendo em vista sua fruição poética e seu uso escolar a partir de um grupo de papiros categorizados como exercitationes scribendi.

Authors: Новенькова Аида Зуфаровна
Published: February 2018

В статье обосновано двойственное влияние теневой экономики на динамику агрегированных показателей регионального социально-экономического развития. Доказано, что в условиях выполнения субъектами теневых экономических отношений преимущественно функции институционального новаторства мезоэкономические показатели характеризуются положительной динамикой (снижение уровня безработицы, приток капитала, увеличение совокупных расходов и др.), в условиях выполнения субъектами теневых экономических отношений преимущественно функций институциональной конкуренции и консервации мезоэкономические показатели характеризуются понижательной динамикой (усиление межрегиональной дифференциации, отток высококвалифицированных работников, снижение объема частных инвестиций, сокращение доходов бюджета и др.). Это определяет необходимость легитимации публичного управления на основе повышения качества и его ориентацию на легализацию неформальных институтов, конгруэнтных институциональному контуру мезоэкономической системы.

Published: February 2018

Purpose: This study aimed at specifying the relationship between perceived organizational justice and job involvement in female teachers of the high school second year in Isfahan city and conducted in a correlation method in 2015-5016.

Methodology: Research population was all female teachers who teach to the student of 2nd year in high schools of Isfahan 6 educational areas (1475 individuals). From among this population, 260 individuals were selected based on Cochran sample mass in a multi-step cluster sampling. Research instruments were organizational justice questionnaire by Colquitt (2010) and job involvement questionnaire proposed by Kanugo (1983). Based on Cronbach's Alpha, the stability of these questionnaires was 80% and 90% for psychological assets and teachers work involvement, respectively. The data were then analyzed using descriptive and deductive statistic including Pierson correlation test, step to step regression.

Main Findings: Results of this study show that there exists a positive, meaningful relation between organizational justice and 4 of its dimensions (procedural, distributional, personal and informational) and job involvement. (p<0.01) results of the multi-regression analysis indicate that organizational justice and 2 dimensions of that (procedural and interpersonal ones) have got the most power to predict teachers' job involvement.

Implications: Results of this study can enrich the knowledge about the relationship between perceived organizational justice and job involvement in female teachers of the high school.

Originality: As per author’s information and belief, first-time relationship between perceived organizational justice and job involvement in female teachers of high school of Isfahan city, Iran.

Wstęp

Podawanie steroidów w ciąży do 34 hbd przyspiesza rozwój dojrzałości płuc płodu i stymuluje wydzielanie surfaktantu, przez co zapobiega występowaniu zespołu zaburzeń oddychania. Udowodniono, że podawanie steroidów prenatalnie powoduje czasowe obniżenie akcji serca płodu o adekwatnej masie ciała (AGA). W pracy podjęto próbę odpowiedzi na pytanie: jak długo utrzymuje się czasowe obniżenie akcji serca płodu (fetal heart rate – FHR) po podaniu steroidów u płodów z wewnątrzmacicznym ograniczeniem wzrastania?

Materiał i metody

Badanie przeprowadzono z udziałem 152 pacjentek Kliniki Ginekologii i Położnictwa SUM w Katowicach, hospitalizowanych w latach 2013–2016, podzielonych na dwie grupy: AGA – 109 przypadków, IUGR – 43 przypadki. W obu grupach została włączona profilaktyka steroidowa – betametazon lub deksametazon. Przeanalizowano zapisy KTG oraz MONAKO wykonane przy przyjęciu pacjentki oraz 24 i 48 godzin po podaniu steroidów, oceniając linię podstawową, epizody bradykardii oraz parametry zmienności LTV i STV. Wyniki opracowano w programie Statistica 12PL.

Wyniki

Bradykardia posteroidowa występowała częściej w grupie AGA niż w grupie IUGR. Po podaniu pierwszej dawki steroidów zauważono istotnie niższą wartość FHR w czasie trwania epizodów bradykardii w grupie AGA niż w grupie IUGR (p = 0,0001). Obniżenie FHR bez bradykardii było znamiennie większe w grupie AGA niż w grupie IUGR (p = 0,0001). Średnia wartość STV po podaniu drugiej dawki steroidów była znamiennie niższa w grupie AGA niż w grupie IUGR (p = 0,006). Ciśnienie parcjalne tlenu było wyższe w grupie IUGR (p = 0,001).

Wnioski

W świetle powyższych wyników wydaje się, że płody z IUGR wykazują lepszą tolerancję podawanych steroidów manifestującą się rzadszym występowaniem bradykardii i wyższymi wartościami STV oraz mniejszymi wahaniami wartości FHR.
A Dislocation-scale Characterization of the Evolution of Deformation Microstructures around Nanoindentation Imprints in a TiAl Alloy

Published: February 2018

In this work, plastic deformation was locally introduced at room temperature by nanoindentation on a γ-TiAl based alloy. Comprehensive analyzes of microstructures were performed before and after deformation. In particular, the Burgers vectors, the line directions and the mechanical twinning systems were studied via accurate electron channeling contrast imaging. Accommodation of the deformation are reported and a scenario is proposed. All features help to explain the poor ductility of the TiAl based alloys at room temperature.
Low-Waste Recycling of CuO-ZnO-Al2O3 Spent Catalysts
Authors: Małecki Stanisław , Gargul Krzysztof
Published: February 2018

CuO-ZnO-Al2O3 catalysts are designed for the low-temperature shift conversion in the process of hydrogen and ammonia synthesis gas production. The paper presents the results of research on recovery of copper and zinc from spent catalysts using pyrometallurgical and hydrometallurgical methods. Under reducing conditions, at high temperature, having appropriately selected the composition of the slag, more than 66% of copper in metallic form and about 70% of zinc in the form of ZnO can be extracted from this material. Hydrometallurgical processing of the catalysts was carried out using two leaching solutions: alkaline and acidic. Almost 62% of the zinc contained in the catalysts has been leached to the alkaline solution and about 98% of copper has been leached to the acidic solution. After the hydrometallurgical treatment of the catalysts, insoluble residue was also obtained in the form of pure ZnAl2O4. This compound can be reused to produce catalysts, or it can be processed under reducing conditions at high temperature to recover zinc. The recovery of zinc and copper from such a material is consistent with the policy of sustainable development and helps to reduce the environmental load of stored wastes.

Energy conversion and distribution (heat and electricity) is characterized by long planning horizons, investment periods and depreciation times, and it is thus difficult to plan and tell the technology that optimally fits for decades. Uncertainties include future energy prices, applicable subsidies, regulation, and even the evolution of market designs. To achieve higher adaptability to arbitrary transition paths, a technical concept based on integrated energy systems is envisioned and described. The problem of intermediate steps of evolution is tackled by introducing a novel paradigm in urban infrastructure design.It builds on standardization, modularization and economies of scale for underlying conversion units. Building on conceptual arguments for such a platform, it is then argued how actors like (among others) municipalities and district heating system operators can use this as a practical starting point for a manageable and smooth transition towards more environmental friendly supply technologies, and to commit to their own pace of transition (bearable investment/risk). environmental friendly supply technologies. Merits are not only supported by technical arguments but also by strategical and societal prospects like technology neutrality and availability of real options.
