Models for assessment of volatile organic compound diffusivities in leather or leather imitates by mercury intrusion porosimetry test
Authors: Yuan Xuzheng , Wang Xuechuan , Zhao Guohui , Jiang Sujie
Published: April 2019

Recent studies have been conducted on the characteristics of volatile organic compound emissions; most of them are focused on wood-based building materials, scarcely mentioned about leather or leather imitates. The volatile organic compound emissions of these products may cause poor indoor (vehicle cabins included) air quality. This article takes formaldehyde as an example to study its diffusion in leather. The porous structure of leather was characterized by carrying out mercury intrusion porosimetry test. The formaldehyde diffusivities in leather was assessed by Blondeau et al.’s, Ataka et al.’s, and Xiong et al.’s models which represent parallel, equivalent, and series interconnection of pores, respectively, and validated through independent liquid inner tube diffusion film emission experiments. The results demonstrated that the fractal dimension of leather is 2.19, which indicated it is a porous medium with self-similar pore structure. Most of the pores in leather were macro pores with average diameter 16.56 μm which contributed to 95.9% of whole porosity and the meso pore with average diameter 0.60 μm which contributed to 4.1%. As far as the liquid inner tube diffusion film emission experiment shows, the Xiong model agrees much better with the experimental results than the other two. The two kinds of pores were considered to be serially connected. It is useful for predicting volatile organic compounds diffusion coefficient in a short time and can be applied to the design and development of low volatile organic compound emission leather or leather imitates within further research.

Published: April 2019

There is a pressing need to establish automated solutions for the rapid, high-throughput, and automatic detection of chromosome aberrations (CAs) in the occupational health surveillance of large-scale radiation workers. Here, we described and verified the accuracy of a new measurement system based on the automatic scanning and analysis of dicentric chromosomes (DICs). The effects of cell number on DIC detection by automatic scanning and analysis were studied, and the distribution of DIC values per cell was calculated. In total, 1088 cases were detected by automatic DIC scanning and analysis in 26 663 radiation workers, and 73 cases were further confirmed by a technician, including 5 cases in which radiation exposure lead to harmful medical consequences. Our approach reduces the workload by 96% and increases the speed of assessment approximately 7-fold. Overall, this study validates the utility of a novel rapid and high-throughput CA detection procedure as a means of occupational health surveillance of large-scale radiation workers.
The Important Role of Contextual Information in Speech Perception in Cochlear Implant Users and Its Consequences in Speech Tests
Authors: Dingemanse J. Gertjan , Goedegebure André
Published: April 2019

This study investigated the role of contextual information in speech intelligibility, the influence of verbal working memory on the use of contextual information, and the suitability of an ecologically valid sentence test containing contextual information, compared with a CNC (Consonant-Nucleus-Consonant) word test, in cochlear implant (CI) users. Speech intelligibility performance was assessed in 50 postlingual adult CI users on sentence lists and on CNC word lists. Results were compared with a normal-hearing (NH) group. The influence of contextual information was calculated from three different context models. Working memory capacity was measured with a Reading Span Test. CI recipients made significantly more use of contextual information in recognition of CNC words and sentences than NH listeners. Their use of contextual information in sentences was related to verbal working memory capacity but not to age, indicating that the ability to use context is dependent on cognitive abilities, regardless of age. The presence of context in sentences enhanced the sensitivity to differences in sensory bottom-up information but also increased the risk of a ceiling effect. A sentence test appeared to be suitable in CI users if word scoring is used and noise is added for the best performers.
Predictors of Student Engagement in Learning Communities
Authors: Baños James H , Noah Jason P , Harada Caroline N
Published: April 2019

Introduction:

Little is known about what factors predict student engagement in learning communities (LCs). At our institution, we recently converted from an informal, unfunded program with volunteer mentors and no participation requirement to a formal, funded program with a structured curriculum, dedicated mentors, and required attendance. We sought to identify factors that predict student engagement in this new program.

Methods:

Medical students from all 4 years were invited to complete a survey that included self-rating of their level of engagement with their LC. We hypothesized that student engagement would be (1) higher in the new, formal program compared with the informal program; (2) lower among older students; and (3) higher among students who value collective activities for stress management.

Results:

In total, 75% of students completed the survey. Students who participated in the formal LC program reported significantly higher engagement than those who experienced the informal version. Older, out-of-state, and underrepresented in medicine (URiM) students reported lower levels of engagement compared with younger, in-state, and non-URiM students, but gender and campus assignment were not associated with level of engagement. Students who valued participation in extracurricular activities, service work, and time with friends or family all had higher levels of engagement in LCs compared with those who valued more solitary activities.

Discussion:

The formal, structured LC program was associated with higher levels of engagement than the informal program, and engagement was maintained throughout the 4-year curriculum. Subgroups of students reported lower engagement in LCs, and future research is needed to better understand and address this variability in engagement. This study is limited by the fact that students are only surveyed once annually, at a single institution, and our measure of engagement is brief and dependent on student self-report. In addition, it is not possible to discern from this study which components of the formal LC program were most strongly associated with high engagement.
Collaborative diagnosis between clinician and patient: why to do it and what to consider
Authors: Hackmann Corinna , Wilson Jon , Perkins Amorette , Zeilig Hannah
Published: April 2019

This article discusses findings from the literature and our own research related to the experience of the diagnostic process in mental healthcare, primarily from the perspective of patients, and it focuses on the benefits of collaboration. A common finding throughout our research is that, if a diagnostic process is undertaken, the majority of patients want to be actively involved and feel valued in it. This helps ensure that they find the process and the resulting diagnosis to be meaningful, informative and useful. We believe that collaboration could also mitigate some of the reported negative unintended consequences of diagnosis, including feeling stigmatised, labelled and disempowered. Our work has led us to conceive of diagnosis as having two overarching elements: the diagnostic process and the resulting diagnostic label. This article focuses specifically on the diagnostic process; we do not consider here the debate surrounding the evidence base for the validity of psychiatric classification.

LEARNING OBJECTIVES

After reading this article you will be able to:

•

understand patients' experiences of the diagnostic process

•

achieve a shared and collaborative diagnostic process with patients

•

reflect on potential barriers and facilitators to collaborative diagnosis in your own practice.

PURPOSE

A randomized, double-blind, phase III study of idelalisib (IDELA) plus rituximab versus placebo plus rituximab in patients with relapsed chronic lymphocytic leukemia (CLL) was terminated early because of superior efficacy of the IDELA-plus-rituximab (IDELA/R) arm. Patients in either arm could then enroll in an extension study to receive IDELA monotherapy. Here, we report the long-term efficacy and safety data for IDELA-treated patients across the primary and extension studies.

PATIENTS AND METHODS

Patients were randomly assigned to receive rituximab in combination with either IDELA 150 mg twice daily (IDELA/R; n = 110) or placebo (placebo/R; n = 110). Key end points were progression-free survival (PFS), overall response rate (ORR), overall survival (OS), and safety.

RESULTS

The long-term efficacy and safety of treatment with IDELA was assessed in 110 patients who received at least one dose of IDELA in the primary study, 75 of whom enrolled in the extension study. The IDELA/R-to-IDELA group had a median PFS of 20.3 months (95% CI, 17.3 to 26.3 months) after a median follow-up time of 18 months (range, 0.3 to 67.6 months). The ORR was 85.5% (94 of 110 patients; n = 1 complete response). The median OS was 40.6 months (95% CI, 28.5 to 57.3 months) and 34.6 months (95% CI, 16.0 months to not reached) for patients randomly assigned to the IDELA/R and placebo/R groups, respectively. Prolonged exposure to IDELA increased the incidence of all-grade, grade 2, and grade 3 or greater diarrhea (46.4%, 17.3%, and 16.4%, respectively), all-grade and grade 3 or greater colitis (10.9% and 8.2%, respectively) and all-grade and grade 3 or greater pneumonitis (10.0% and 6.4%, respectively) but did not increase the incidence of elevated hepatic aminotransferases.

CONCLUSION

IDELA improved PFS and OS compared with rituximab alone in patients with relapsed CLL. Long-term IDELA was effective and had an expected safety profile. No new IDELA-related adverse events were identified with longer exposure.

Frame Models Forming English Metadiscourse
Authors: Федотова Оксана , Fedotova Oksana
Published: April 2019

The paper presents fiction as a multi-layer unit. On the one hand, there is fictional reality in which characters live and act. On the other hand, there is a specific form of presentation of the plot to the reader, fiction narrative metadiscourse. The paper shows that metadiscourse unites the plot and the author’s metadiscourse into fiction text. Metadiscourse is presented as a two-layer structure, which consists of the inner conceptual layer and the outer layer, which includes the system of language means the choice of which is made on the basis of conceptual frame models. The paper describes frame models of metadiscourse forming the inner structure of the text. They are: the frame model of space and time, the frame model of generalization and the frame model of communicative interaction between the writer and the reader.

Cel pracy

W odniesieniu do choroby afektywnej dwubiegunowej (ChAD), dotychczasowe prace wskazują na zaburzenia ruchów sakadycznych, głównie pod postacią wydłużenia czasu reakcji (latencji) w testach prosakad i antysakad. Dotychczas nie przeprowadzono oceny ruchów wergencyjnych gałek ocznych u osób z ChAD. Głównym celem naszego badania jest ocena parametrów konwergencji (zbieżne ruchy gałek ocznych) w tej grupie klinicznej.

Metoda

Do badania włączono 30 pacjentów z ChAD w stanie remisji objawowej i 23 zdrowych ochotników. Uczestników poddano badaniu optometrycznemu oceniającemu punkt bliski konwergencji przy użyciu pręta fiksacyjnego. Badanie okulometryczne przeprowadzono przy pomocy okulografu wykorzystującego promieniowanie podczerwone z dedykowanym stymulatorem wergencji.

Wyniki

Pacjenci z ChAD wykazali istotnie większy średni błąd pozycji konwergencji do celu oraz większą liczbę wtrąceń sakadycznych w porównaniu do grupy kontrolnej. Analiza składowych głównych przeprowadzona na zmiennych okulometrycznych pokazała istotne różnice między pacjentami z ChAD a zdrowymi ochotnikami. Wykazano obecność istotnych korelacji między zaburzeniami ruchów wergencyjnych a liczbą wtrąceń sakadycznych.

Wnioski

Pacjenci z ChAD ujawnili zaburzenia ruchów wergencyjnych gałek ocznych podobne do zaburzeń opisywanych w trakcie śledzenia bodźców poruszających się w płaszczyźnie czołowej. Podczas gdy zaburzenia wergencji były opisywane w innych zaburzeniach psychicznych, nasza praca po raz pierwszy obiektywnie zmierzyła to zjawisko w ChAD.
EMBATES CULTURAIS E PRODUÇÕES FEMINISTAS: UM DIÁLOGO NECESSÁRIO
Authors: Miranda Juliana Aparecida Dos Santos
Published: April 2019

Neste artigo serão abordados os conceitos de cultura pensando primordialmente em sua relação com produções e manifestações artísticas, mais especificamente música de protesto feministas, e violências contra a mulher. Considerando a abrangência cultural tanto em seu viés artístico quanto ao que diz respeito aos hábitos e costumes cultivados por determinadas comunidades, buscaremos analisar, ou interpretar, o modo pelo qual a cultura artística de produtoras feministas tem trabalhado para descontruir com a cultura das violências contra as mulheres através de denúncias contidas em suas produções musicais. Partindo do pressuposto de que todo discurso pode ser ao mesmo tempo um contra-discurso, podemos pensar que a instância de discurso utilizada pelas bandas feministas na produção de letras musicais protestante pauta-se no desejo de resposta aos discursos machistas existente na sociedade como um todo. Desse modo, a música de protesto feminista, através do discurso artístico, instaura uma nova percepção em torno do feminismo e suas manifestações. Essa nova percepção aponta para outro aspecto importante da realização deste estudo: notar o lugar de fala das mulheres no cenário artístico marginal e o modo pelo qual o feminismo tornou este lugar possível. Assim, teremos uma leitura sobre a cultura da violência contra a mulher, pensando em como esta cultura se estabeleceu e se mantem até os dias atuais, faremos uma abordagem sobre os modos de produção artística feminista, através das canções de protesto feministas, promovendo o diálogo entre essas produções e a denúncia e as estratégias de combate contra as violências contra as mulheres.

Authors: Kuusisto Sanna , Holmes Michael V , Ohukainen Pauli , Kangas Antti J , Karsikas Mari , Tiainen Mika , Perola Markus , Salomaa Veikko , Kettunen Johannes , Ala-Korpela Mika
Published: April 2019

BACKGROUND

HDL-mediated cholesterol efflux capacity (HDL-CEC) is a functional attribute that may have a protective role in atherogenesis. However, the estimation of HDL-CEC is based on in vitro cell assays that are laborious and hamper large-scale phenotyping.

METHODS

Here, we present a cost-effective high-throughput nuclear magnetic resonance (NMR) spectroscopy method to estimate HDL-CEC directly from serum. We applied the new method in a population-based study of 7603 individuals including 574 who developed incident coronary heart disease (CHD) during 15 years of follow-up, making this the largest quantitative study for HDL-CEC.

RESULTS

As estimated by NMR-spectroscopy, a 1-SD higher HDL-CEC was associated with a lower risk of incident CHD (hazards ratio, 0.86; 95%CI, 0.79–0.93, adjusted for traditional risk factors and HDL-C). These findings are consistent with published associations based on in vitro cell assays.

CONCLUSIONS

These corroborative large-scale findings provide further support for a potential protective role of HDL-CEC in CHD and substantiate this new method and its future applications.
Optimization and Comparison of Information-Dependent Acquisition (IDA) to Sequential Window Acquisition of All Theoretical Fragment Ion Spectra (SWATH) for High-Resolution Mass Spectrometry in Clinical Toxicology
Authors: Whitman Jeffrey D , Lynch Kara L
Published: April 2019

BACKGROUND

Untargeted data acquisition on high-resolution mass spectrometers (HRMSs) has been used in clinical toxicology for screening and identifying unknown compounds in patient samples. A common modality for untargeted HRMS data acquisition is information-dependent acquisition (IDA), which analyzes the most abundant small molecules within an acquisition cycle. This process can potentially lead to false negatives of clinically relevant compounds at low concentrations. Sequential window acquisition of all theoretical fragment ion spectra (SWATH) has emerged as a method of unbiased, untargeted HRMS data acquisition in which no spectral data are lost. SWATH has yet to be optimized and assessed for use in clinical toxicology.

METHOD

We developed a variable-window SWATH method (vSWATH) and compared it to IDA by limit of detection studies in drug-supplemented urine (81 compounds) and against a retrospective cohort of 50 clinical urine samples characterized by LC-MS/MS.

RESULTS

vSWATH had a lower limit of detection than IDA for 33 (41%) drugs and metabolites added into urine samples. Both IDA and vSWATH were equivalent in discovering compounds from clinical urine samples and confirmed 26 additional compounds not previously discovered by targeted LC-MS/MS. Lastly, the unbiased acquisition of spectra in vSWATH allowed for identification of 5 low-abundance compounds missed by IDA.

CONCLUSIONS

This vSWATH method for clinical toxicology demonstrated equivalent analytical sensitivity and specificity for untargeted drug screening and identification in urine samples. vSWATH provided the additional benefit of collecting all tandem mass spectrometry spectra in a sample, which could be useful in discovering low-abundance compounds not discovered by IDA.

Published: April 2019

Aim: This study aimed to compare the physicochemical, the biochemical, and the antioxidant characteristics of unifloral bitter honey and polyfloral sweet honey. Materials and Methods: Unifloral bitter and polyfloral sweet honey samples were, respectively, harvested in January and July, and then, they were extracted by the traditional method. The markers of refractive index, pH, free acidity, Brix index, density, reducing sugars, total polyphenols, flavonoids, tannins, 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric reducing/ antioxidant power (FRAP) were evaluated. Results: The obtained results showed that the physicochemical parameters are within the normal ranges, in which they meet the international standards (Codex Alimentarius). For biochemical constituents, matching concentrations of reducing sugars (glucose+fructose) were observed in both samples, while that of sucrose were very low in unifloral than polyfloral honey. The levels of the active ingredients showed a difference in total polyphenols and tannins of the two types of honey studied, whereas that of flavonoids were almost similar. The antioxidant activity of various samples evaluated by DPPH and FRAP indicated that unifloral has a superior activity. Conclusion: Compared to polyfloral honey, unifloral bitter honey has lower sucrose, high total polyphenols, and tannins levels, in addition to higher antioxidant potential.
Política colonizadora de España en Alta California en la correspondencia de los padres Franciscanos 1769-1795
Authors: Tóth Ágnes
Published: April 2019

What were the reasons for the inability of the Viceroyalty of Spain to consolidate its power in Alta California? The aim of the essay is to provide an answer to this question, examining the interpretation of Franciscan fathers serving in missions of the region about the causes of that failure. The letters and other documents of the Franciscans—either unintentionally or consciously—represent a very modern point of view on power relations and government measures; they impeach the government for the lack of certain economic and commercial conditions that would encourage free trade and development in the region. In their interpretation, the essential prerequisite of development and wealth creation is the dilingent, continuous labor of the population. However, in the case of Alta California, this is hindered by the overregulation of commerce and the regulation of prices on behalf of the government. The Franciscans also note that as a result of the strict land ownership laws, the region does not attract much settlers, resulting in a decrease of urban development. Due to the lack of motivating factors, the main philosophy of the residents of the region is “maybe tomorrow”.
De la dictadura a la democracia : Manuel Fraga Iribarne
Authors: Anderle Ádám
Published: April 2019

The essay examines the political career of the renowned Spanish conservative politician. As a young jurist, Fraga Iribarne quickly developed an academic, diplomatic and political career in the Spanish Franco regime after the Second World War; he even occupied the—rather infamous—post of the Minister of Interior. Still, Fraga Iribarne was one of the few Francoist statesmen who recognized the importance of a democratic transition, and he became one of the key figures of the Spanish transition after the death of Franco. He also participated intensely in the creation of the democratic constitution of 1978, founded and presided People's Alliance (Alianza Popular), a party of conservative orientation, and was the President of Galicia's Xunta for 15 years. The author emphasizes the key role of Fraga Iribarne in the democratic transition, pointing out that it was him who, in the autumn of 1976, introduced the Communist leader Santiago Carrillo to the members of the Francoist elite club, Club 21st Century, causing a great stir in the Madrid élite. Fraga's move was a clear statement that in democratic pluralistic party politics, communist and other leftist elements also have the right to be represented. Still, the documents of the era also point out that Juan Carlos, the young monarch, also had a decisive role in the positive reception of democratic ideas by the Francoist élite.
Algunas cuestiones de la formación del participio en español y portugués
Authors: Krekovics Diana
Published: April 2019

The aim of this paper is a historical-comparative presentation of the development of past participle forms in the Iberoromanic languages. First of all, we focus on the Latin forms with desinence -utus which have gradually disappeared in those languages that are spoken in the Iberian Peninsula. After a rapid glance over the formation of participles in the languages in question (Spanish, Catalan, Portuguese) we make comparison with the help of statistical datas that were obtained from Spanish and Portuguese literary and legal texts, written in the 13th, 14th and 15th centuries. The subject of this comparison is the incidence rate in the aforementioned centuries and genres of those Spanish and Portuguese past participles that earlier had the desinence - utus in Latin.
José Ortega y Gasset y los principios de la psicología científica en España - "escorzo"
Authors: Horváth Petra
Published: April 2019

My essay discusses the rise of scientific psychology in Spain and the role José Ortega y Gasset played in its formation. From the second half of the 19th century, as part of the effort to catch up with the scientific development that took place in Europe, Spain turned with great interest towards the latest scientific theories of the day, as well as towards the network of ideas that served as their ground and context. The greatest Psychological Schools – Psychoanalysis, the Gestalt theory, Phenomenology, among others – soon appeared in Spain, and by the beginning of the 20th century Spanish scientific psychology was formed. In the institutionalization of this new science, the Spanish philosopher, José Ortega y Gasset, took a leading part. Already as a young man Ortega showed great interest in psychology and as a mature philosopher he even dedicated an entire university course to the question of Psychology with the title “System of Psychology”, in 1915-16. These lectures -which embedded various central psychological issues in philosophical discourse – are of great interest even today.

Magia bruniana y socialismo utópico : el concepto de imaginación dialéctica de Alfonso Sastre en "dónde estás ulalume, dónde estás"
Authors: Diéguez Mónica Poza
Published: April 2019

“In 1978 Alfonso Sastre (1926-) published his Crítica de la imagination, a capital work to understand his theory of drama, as Sastre defines and concretes the force of his writing on it. Imagination becomes a decisive element in Sastre's works as he has stated in multiple interviews and in the present book as well –which is the first in a series of publications regarding the topic. In this article I analyze the concept of “dialectic imagination” as proposed by Alfonso Sastre in relation with that other concept of imaginatio developed by the hermetic tradition from Classical antiquity to Neoplatonism. More precisely, I will focus my analysis of ¿Dónde estás, Ulalume, dónde estás? (1990) to underline the connections between Sastre's dialectic imagination and some interpretations regarding the works and thinking of Giordano Bruno.”

Relación entre las formas de un verbo supletivo : el caso del gallego, comparado con el de otras lenguas iberorrománicas
Authors: Szijj Ildikó
Published: April 2019

The verb 'go' (Spanish, Portuguese, Galician ir, Catalan anar) is a suppletive verb in the
Iberian romance languages. The roots and their distribution in the paradigm are similar in standard
Spanish, Portuguese and Galician, but rather different in Catalan. There is a diachronic variaton
and a synchronic difference between these languages in the 4th and 5th person of the present
^ indicative mood. The variants can also be observed in dialects: according to the Galician Unguistic
Atlas (Atlas lingüístico galego), the root can vary in the Galician linguistic territory in the previous
two forms and in the 5th person of the imperative mood. These three forms within the paradigm are
related in that thy are the "truly" arhygotonic forms in the three present tenses and they have the
same morphological structure.
El partido aprista cubano : 1933-1937
Authors: Anderle Ádám
Published: April 2019

This study is the reinterpretation of a previous study, published in 1975 by the same
author, in which he presented the political fights between the Cuban communists (PCC) and
Apristas in the 1930s. This research is based on archival sources, party brochures (folletos,
volantes) and contemporary printed materials. The study mitten in the 1970s accepted the
official communist standpoint and as a result showed a strongly negative, anti-communist image
of the Cuban Aprista Tarty (PAC) describing it as a party which hindered the Cuban
revolutionary movement and was in favour of American interests.
After the publication of the study in Caracas (1978) various Cuban PAC leaders
expressed their criticism against it.
As a result, the author started his research over. He had the opportunity to look into
documents in a few private archives in Havana, enriched his printed material collection,
examined the new results in the topic's literature, and conducted several interviews. Besides
this, he critically re-read his previously collected materials (both archival and printed) from the
1970s. In this study the author shows the activity of PAC in an extraordinaty way based-sn
his recent research.
The study emphasises that the ideas of APRA-PAC share various similarities with the
ideas ofJosé Martí who did not think in political pluralism: his concept of democraty meant
social and not political democray. PRC founded by him can be understood as a (future) state
party as well. The final conclusion of the study is that it was not only Marti's, but also PAC's
ideas that could have a great role in forming the ideology of Fidel Castro's Movement.

Authors: Csikós Zsuzsanna
Published: April 2019

The article analyses the figure of La Malinche in three least-known theatrical texts of the 20th century Hispanic Literature: La aprendiz de bruja of the cuban writer, Alejo Carpentier, Todos los gatos son pardos of the mexican Carlos Fuentes and the spanish Ramón Sender’s Jubileo en el Zócalo. Starting from the historical events and the reality will be examined her enigmatic rol, her tragic and contradictory destination in these fictions. The different views of the three works make it possible to present the indian woman’s and her nation’s identity.
ДОКУМЕНТНАЯ КОММУНИКАЦИЯ В КОНТЕКСТЕ ЛИНГВИСТИЧЕСКОЙ ЭКСПЕРТИЗЫ
Authors: Kushnir Olga , Martyshev Ivan
Published: April 2019

В статье рассматривается проблема, находящаяся на стыке документоведения, лингвистики и юриспруденции, − проблема качества текстов официальных документов, прежде всего − документов, обладающих юридической силой. Классификация документов на официальные и иные проводится на основании свойства документа воздействовать на правоотношения, или иметь юридическую силу.  Применяемое в документоведении понятие «юридическая значимость документа» применимо как к официальным, так и к иным документам. По мнению авторов, принципиальным различием между указанными свойствами документов является временнáя соотнесенность самих процессов: возникновение документа и возникновение события или действия, с которым документ связан юридической силой или юридической значимостью: юридическая сила связывает документ с событиями или действиями, которые наступают, как правило, после издания документа, а юридическая значимость связывает документ с произошедшими событиями / совершенными действиями. Грань между двумя процессами, вызывающими проявление указанных свойств документа, весьма зыбкая. При этом один документ может обладать одновременно и юридической силой, и юридической значимостью. Предметом лингвистической экспертизы чаще всего становятся тексты официальных документов, которые обладают юридической силой, поскольку их собственно правовая  и социальная значимость выше, чем у всех других документов. Но и само свойство юридической силы у разных видов документов различно и зависит от правового статуса и компетенции автора (авторов) документа и от его функционального назначения. В практике лингвистической экспертизы документных текстов различают экспертизу, проводимую на стадии проектирования текста документа, и экспертизу, проводимую на стадии его применения: в первом случае проявляется превентивная функция лингвистической экспертизы, во втором – детективная. Лингвистическая экспертиза документных текстов, по заключению авторов, должна получить четкий институциональный статус в документной коммуникации и в системе государственного и муниципального управления, и на корпоративном (локальном) уровне.

Objective

Osteoporosis is the most common metabolic disease of the bones. Osteoporosis reduces bone density, predisposes a person to fractures, and imposes high costs on societies. Osteoporosis develops from a variety of causes, one of the most significant is vitamin D deficiency. This study investigates the impact of vitamin D on osteoporosis.

Materials and Methods

In this clinical trial, 400 patients referred to the Bone Density Clinic of Kowsar Hospital in Semnan were selected by convenience sampling method. Bone densitometry tests were carried out using DEXA (x-ray absorptiometry) and serum vitamin D levels were measured by the ELISA method. Subjects with vitamin D deficiency were treated for 8 weeks with (50,000 Vitamin D units per week. At the end of the treatment period, all subjects were evaluated for bone density and the results of both groups were compared.

Results

13% of subjects had osteoporosis and 14.2% had osteopenia. 19% of subjects had vitamin D deficiency, 38.8% had insufficient levels of vitamin D, and 42.3% had sufficient vitamin D levels. The level of vitamin D in patients with osteoporosis (5.50 ± 5.5 ng/ml) was less than those with osteopenia (7.83 ± 4.8 ng/ml) and those with normal bone mineral density (23.88 ± 18.42 ng/ml) (P <0.001). The prevalence of osteoporosis in the intervention group after intervention with vitamin D was significantly lower than the control group (32.3 versus 67.7 and P <0.001).

Conclusion

The prevalence of serum vitamin D deficiency in osteopenic and osteoporotic individuals was higher than in normal subjects, with a significant relationship between age and sex. Thus, treatment with vitamin D improves bone density indices.

Jatropha oil [JO] based poly (esteramide-urethane) coatings embedded with fumed silica nanoparticles were prepared. JO was converted to N,N-bis(2-hydroxy ethyl) JO fatty amide (HEJA) and was further modified by a tetrafunctional carboxylic acid(trans1,2 diaminocyclo-hexane-N,N,N’,N’,-tetraacetic acid) to form poly (diamino cyclohexane esteramide) (PDCEA). PDCEA was then treated with toluene 2,4-diisocynate and fumed silica to prepare poly(diamino cyclohexane urethane esteramide) (PUDCEA) nanocomposite. The formation of PDCEA and PUDCEA nanocomposites was confirmed by FTIR,1H &13C NMR spectroscopic techniques. The thermal behavior and morphology of PUDCEA nanocomposite coatings were investigated by TGA/DTG, DSC, SEM, EDX spectroscopy. PUDCEA nanocomposites were applied on carbon steel and their coatings were produced at room temperature. The properties of these nanocomposite coatings were investigated by standard analytical methods. The PUDCEA-3 nanocomposite showed good anticorrosion and physico-mechanical performance. These naocomposite coatings can be employed safely upto 200oC.

Background

Adolescence is a critical stage of life which is characterized by rapid biological, social and emotional development. India has the highest adolescent population, however, there is paucity of literature reporting the sleep quality among adolescents.

Objective

To determine the sleep quality and its associated factors among adolescents residing in selected villages of rural Puducherry.

Materials and methods

A community-based cross-sectional study was conducted among adolescents during March and April 2018. Two out of four villages were randomly selected and all the adolescents were contacted through a household visit and a questionnaire was administered. The semi-structured questionnaire contained socio-demographic details of adolescents and details on living environment. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) scale. Sleep quality is expressed as a proportion with a 95% confidence interval (CI). The association of socio-demographic characteristics with poor sleep quality is reported as a prevalence ratio.

Results

The total number of adolescents interviewed was 789. The mean age of the study participants was 14.1 (±2.4) years and the majority, 440 (55.8%) were boys and 684 (86.7%) belonged to a nuclear family. More than a quarter, 210 (26.6%) belonged to the middle class as regards socio-economic status. Environmental assessment of households showed more than half, 456 (57.8%) were staying in a “pucca” house and the majority, 642 (81.4%) had adequate cross ventilation. The prevalence of poor quality of sleep among the adolescents was 2.5% (95% CI: 1.6%–3.9%). It was found that higher educational level [adjusted prevalence ratio (aPR) – 3.43] and belonging to higher socio-economic class (aPR – 5.48) were found to be significant determinants for poor quality of sleep among adolescents.

Conclusion

The current study found that only 2.5% of the adolescents have poor sleep quality. Adolescents with higher educational level and higher socio-economic status were more prone to have poor quality of sleep.
A Simplified Indirect Technique for the Measurement of Mechanical Power in Three-Phase Asynchronous Motors
Authors: Bucci Giovanni , Ciancetta Fabrizio , Fiorucci Edoardo , Ometto Antonio , Segreto Maria Anna
Published: April 2019

This paper presents an indirect method for measuring the mechanical power produced by three-phase induction motors. The proposed technique is based on the hypothesis that three-phase induction motors are balanced systems that transform electrical power into mechanical one. The measurement of a single phase current is used to estimate the mechanical power generated at the axis. The relationship between electric current and mechanical power is generally non-linear. By expressing the quantities in p.u., this trend is approximated with a second order polynomial. From the analysis of the mechanical power characteristics related to 13 motors we obtained the parameters of the interpolating parabolic curves of motors from 1.1 kW to 75 kW rated power. The proposed technique can be easily adopted in order to monitor the mechanical power of three phase induction motors using only one phase current transducer. Starting from the motor nameplate no experimental measurement or other data are necessary to estimate the mechanical power. This technique can be widely used in low cost multipoint measurement system able to monitor the mechanical power where no other transducer or voltage divider are necessary.
Contrasting Preterite and Imperfect use among advanced L2 learners: Judgments of iterated eventualities in Spanish
Authors: Salaberry M. Rafael
Published: April 2019

There are numerous studies that analyze the second language (L2) acquisition of aspect (e.g., see overviews and summaries in Ayoun and Salaberry 2005; Bardovi-Harlig 2000; Labeau 2005; Salaberry, 2008; Salaberry and Shirai 2002). The present study focuses on a specific component of tense-aspect: the iteration of eventualities (iterativity and habituality) conveyed with the use of Spanish Preterite and Imperfect respectively. The analysis is based on data from monolingual Spanish speakers and L1 English speakers with near-native competence in the L2 with the use of contextualized grammaticality judgments. The findings of the study show that near-native speakers of L2 Spanish do not distinguish fine-grained representations of aspectual knowledge (iterativity versus habituality), even though they demonstrate native-like judgments with more prototypical uses of aspect. The discussion of the findings points to possible effects of mapping of meaning and form in the L2, as well as possible instructional effects paired with frequency effects prompted by classroom environments.
