Accounting for the differential inter-system bias (DISB) of code observation in GPS+BDS positioning
Authors: Cao Xiang , Wang Qing , Gao Chengfa , Zhang Jie
Published: August 2018

If the associated differential inter-system biases (DISBs) are priori known, only one common reference satellite is sufficient, which is called the inter-system model. The inter-system model can help to maximize the redundancy of the positioning model, and thus can improve the positioning performance, especially in harsh environment. However, in practice use not all receivers can be calibrated with DISBs in advance. In this paper, taking combined GPS and BDS pseudorange positioning as the example, we compare three positioning models and their positioning performance. One is traditional intra-system model, and the other two belongs to the inter-system models, i. e. the model with calibration of DISB and the model with real-time estimation of DISB parameter. Positioning performance using the three models is evaluated with simulated obstructed environments. It will be shown that besides the model with calibration of DISB, the model with real-time estimation of DISB parameter can also effectively improve positioning accuracy and reliability compared with the traditional intra-system model, especially for the severely obstructed environment with only a few satellites observed. When no more than 7 satellites visible, the positioning accuracies in each directions can be improved by no less than 15 %. The proposed model can be used alternatively when no priori DISB calibration is available.

Recent years have witnessed a growing interest in the relationship between academic language registers and school success in the German-speaking education system. However, we still know very little about the actual effects that academic language has on the academic performance of students, for instance, in how far the extent to which academic language is used in subject tasks actually makes these tasks more difficult. It is therefore highly vital that any operationalization of difficulty-inducing linguistic features of tasks is made on solid theoretical and empirical grounds. The purpose of this article is thus to present the linguistic foundation used in an interdisciplinary empirical study in which 1.346 7thand 8thgraders solved a set of subject-oriented tasks from Maths, Physics, German, PE and Music, while the degree of linguistic demands in the tasks was systematically varied. First, the theoretical and empirical research on linguistic difficulty from a range of research discourses is discussed. The findings are merged into a model of linguistic demands. Its operationalization is then illustrated in three linguistically varied versions of the subject-specific tasks. Finally, an outlook on preliminary results of the empirical study is given, which indicate that the categories used in the model actually do produce differences in subject-task difficulty, even though there are a number of effects that need further investigation.

Authors: Maisuradze M. V. , Ryzhkov M. A.
Published: August 2018

High strength silicon steel implemented for manufacturing engineering products, such as aircraft components and various mining equipment, was under consideration. To obtain data for the numerical simulation of the studied steel heat treatment, the following investigations were conducted: (1) plotting of the continuous cooling transformation diagram; (2) identification of the steel microstructure constituents and the temperature ranges of their formation; (3) determination of the heat transfer coefficients of the industrial cooling media for the heat treatment (oil and still air) by the analysis of the cooling curves. The algorithm was developed for quantifying the amount of the microstructure constituents after continuous cooling to the room temperature at the rates 0.025°C/s–75°C/s. The obtained experimental data was implemented in the commercial software package to simulate the heat treatment process of the steel parts. The simulated data (microstructure distribution over the cross-section of the steel parts) was verified using the microstructure investigation of the heat-treated steel parts. A good agreement of the data was obtained.

En este texto nos hemos propuesto acercarnos a una definición propicia de la literatura, en primer lugar procuramos una definición / concepción general, partiendo del vocablo y sus diferentes conceptos a lo largo de la historia; luego  nos detenemos a repasar la convergencia que hay entre los términos individuo, lengua y literatura; de esa manera, nos enfocamos en la exposición y representación del individuo, del ser humano amplio, tanto en su ser como en su visión del mundo, que hay en el espacio literario. Finalmente, planteamos que en esa conversación que es la lectura, el lector puede descubrir su interioridad, ampliar su visión, para construir lo que es en esencia su ser y, también, para entender lo que ve en la naturaleza. Pero más allá todavía, por medio de la lectura literaria, es posible mejorar su condición para escuchar, entender y comprender a los otros.
Los usos de las campañas anti-corrupción en México
Authors: Nieto Nubia Zulma
Published: August 2018

México ha firmado y ratificado las iniciativas más importantes de la lucha contra la corrupción en el mundo. En tanto miembro de la OCDE, G-20, y miembro activo de las Naciones Unidas, la Organización de los Estados Americanos, el Fondo Monetario Internacional, y la Banca Mundial, México ha acordado luchar contra la corrupción. A nivel nacional, cada presidente como parte de su programa Nacional ha incluido iniciativas anti-corrupción en sus agendas políticas. Sin embargo, los niveles de corrupción e impunidad en México continúan siendo altos, lo cual plantea las siguientes preguntas: ¿Por qué, los políticos nacionales prometen frenar la corrupción al principio de sus gobiernos? ¿Porqué los políticos nacionales que prometen reducir la corrupción al finalizar sus gobiernos se ven envueltos en asuntos de corrupción? ¿Están los políticos mexicanos comprometidos en luchar contra la corrupción? Este artículo pretende analizar estas cuestiones, y se embarca en una exploración de las campañas de lucha contra la corrupción como uno de los pilares del sistema político mexicano desde el gobierno de José López Portillo (1976-1982) hasta Enrique Peña Nieto (2012-2018).

Published: August 2018

A study was carried out on biomass, shoot density and leaf production variability in three Thalassia testudinum meadows under different environmental characteristics in Nuevitas Bay, Cuba, in different seasons. The first site has muddy-sandy sediments and it is affected by bottom trawl fishing; the second has sandy sediments and it is affected by waste-water discharges, and the third has sandy-muddy sediments and no human impacts are present. Leaf, rhizome, and root biomass, daily production of leaves, density of short shoots, and length and width of leaves were estimated five times in a year. Seasonal variations were observed, with higher values of leaf and rhizome biomass, short shoot density, and daily production of leaves occurring in spring and summer. Spatial differences seem to be related to the environmental characteristics of each site: Leaf daily production, leaf biomass and leaf length were lower, and root biomass was higher in the site where sediments are impacted by fishing with bottom trawls; short shoot density and rhizome biomass were higher in the nonaffected site. Lower values of root biomass appeared where waste-water discharges occurred.Se realizó un estudio de la variación de la biomasa, la densidad de vástagos y la producción de hojas en tres praderas de Thalassia testudinum con diferentes características ambientales en la bahía de Nuevitas, Cuba, en diferentes épocas del año. El primer sitio tiene sedimentos fango-arenosos y está afectado por pesquería de arrastre; en el segundo, el sedimento es arenoso y se vierten aguas residuales en su cercanía, y el tercero, con sedimentos arenoso-fangosos, no está afectado por impactos antropogénicos. La biomasa de hojas, rizomas y raíces, la producción diaria de hojas, la densidad de vástagos, y el largo y ancho de las hojas fueron estimadas cinco veces en un año. Se observaron variaciones estacionales, con los valores más altos de biomasa de hojas y de rizomas, densidad de vástagos y de la producción diaria de hojas en primavera y verano. Las variaciones espaciales parecen estar relacionadas con las características de cada sitio: La producción diaria de hojas, la biomasa de hojas y su longitud fueron menores, y la biomasa de raíces mayor, donde los sedimentos están impactados por la pesquería con arrastre; la densidad de vástagos y la biomasa de rizomas fueron mayores en el sitio no afectado por ninguna acción antrópica. Los menores valores de la biomasa de raíces aparecieron donde se realiza la descarga de residuales.

Published: August 2018

OBJECTIVES:

We studied neonatal cortical brain response to 4 types of nonpharmacological analgesia (oral glucose, expressed breast milk, maternal holding plus oral glucose, breastfeeding). We aimed to assess the differential effect of oral solutions (glucose, breast milk) given alone or combined with the maternal-infant relationship (holding, breastfeeding).

METHODS:

Eighty healthy term newborns undergoing a heel stick were randomly assigned to 4 parallel groups of 20 infants each: group 1, infants received a glucose solution on a changing table; group 2, infants received expressed breast milk on a changing table; group 3, infants received a glucose solution in their mothers’ arms; and group 4, infants were breastfed by their mothers. Cortical activation in parietal, temporal, and frontal cortices was assessed by multichannel near-infrared spectroscopy. Pain expression was also evaluated.

RESULTS:

Oral glucose alone or combined with maternal holding was associated with no cortical activation during heel stick. Expressed breast milk was associated with localized bilateral activation of somatosensory and motor cortices (P < .01). Breastfeeding was associated with extensive bilateral activation of somatomotor, somatosensory, and right parietal cortices (P < .01). Pain expression was lower with the maternal-infant relationship (P = .007).

CONCLUSIONS:

Oral glucose, either alone or combined with maternal holding, appears to block or weaken cortical pain processing. Breast milk alone is associated with localized cortical activation. Breastfeeding is associated with extensive activation and may act by extending cortical processing. Maternal relationship, both combined with oral glucose and in breastfeeding, shows the greatest analgesic effect, although the neural patterns involved are distributed differently.

Communication is the performance and interpretation of messages between communication units that are part of a particular organization. Employee engagement is the degree to which people are known from their work, actively participate in them, and consider their achievements important to self-esteem. Organizational citizenship behavior is an optional behavior that is not part of an employee's formal work obligations, but supports the functioning of the organization effectively. Employee performance is the work quality and quantity achieved by a person in carrying out his function in accordance with the responsibilities given to him.

The purpose of this study was to examine and analyze the effect of communication and employee engagement on organizational citizenship behavior and employee performance at PT. PLN (Persero) Distribution of Bali. The sampling technique used was proportional random sampling. The sample in this study were 62 employees. Data analysis method used is SEM (Structural Equation Modeling) analysis based on component or variance, namely PLS (Partial Least Square).

FECAL CONTAMINATION AND THE PROPORTION OF HUMAN-ASSOCIATED E. coli ALONG NHUE RIVER, VIET NAM
Authors: Tanaka Mai
Published: August 2018

According to rapid urbanization in Asian countries, the amount of domestic wastewater discharge has been increasing, resulted in water pollution and potential health risk on human. To secure biological safety of rivers, it is critical to understand the sources of contamination. The present study applied the human-associated E.coli genetic marker (H8) to characterize the source of microbial contamination. E. coli concentration and other pollutants indices were investigated at 10 sites along the river: S1 (upstream) – S10 (downstream). For 220 E. coli isolates collected from river water samples, Real-Time PCR was performed with H8. The results showed that organic pollutants peaked at the middle stream, although they were originally low at upstream (S1). The positive proportion of H8 with E. coli peaked at 40.9 % at middle stream (S6), which was significantly higher than S1 (4.5 %) (p = 0.012). This high proportion implied the relative dominance of human-associated E. coli, which were in line with a large inflow of sanitary wastewater in middle stream, indicated by land use along the river. Thus, we successfully demonstrated the usefulness of H8 to track the source of microbial contamination in the river.
ACUTE TOXICITY OF THE ETHANOL EXTRACT AND ETHYL ACETATE FRACTION OF EUPATORIUM FORTUNEI TO DAPHNIA MAGNA
Authors: Nga Pham Thanh
Published: August 2018

Previous studies have shown that the crude ethanol extract and its ethylacetate fraction of the plant Eupatorium fortunei Turcz strongly inhibited the growth of a harmful freshwater cyanobacterium Microcystis aeruginosa. However, the perspective of using these plant extracts as alternative algicides takes into account their potential risks to other species in aquatic ecosystems, including Daphnia magna. The current study presents the acute toxicity of the extracts to D. magna. The median lethal concentrations, immobilizing 50 % of D. magna, (LC50) after 24 and 48 h of the ethanol extract were 247 and 183 mg L-1, respectively. In the exposure to ethyl acetate fraction, the values of 24h-LC50 and 48h-LC50 were 47 and 13 mg L-1, respectively. The values of dissolved oxygen (DO) and pH in the control and treatments had little change during the 48-hour experiment period, fluctuating from 6.44 ÷ 7.90 and 6.07 ÷ 7.78 mg L-1, respectively, and they were still good conditions for D.magna growth. Finally, these results prove clearly that the ethyl acetate fraction is more toxic to the freshwater cladoceran than the ethanol extract. To our knowledge, it is the first report of the acute toxic estimation of E. fortunei extracts to zooplankton species, D. magna. Chronic toxicity of these extracts to D. magna needs to be studied in next step.
HUMAN HEALTH RISK IMPLICATION FROM CADMIUM AND LEAD CONTAMINATION AT LEAD-ZINC MINE AREA, NORTHERN VIET NAM
Authors: Thu Hien Nguyen Thi
Published: August 2018

This study was conducted to investigate cadmium (Cd) and lead (Pb) accumulation in soil, vegetables, and residential hair in the vicinity of Cho Dien mine. Health risk assessment of those was also evaluated based on vegetables contamination, including the average daily dose (ADD) and hazard quotient (HQ) calculation. The concentration of Cd and Pb in soil was 2.1 and 8.4 times higher than QCVN 03-MT:2015/BTNMT. The highest concentrations of both metals were found at 56.2 mg/kg and 23.266 mg/kg near mine areas and tailings dam. Among eight vegetables investigated, the common leafy species consumed by local people, Sauropus androgynous and Ipomoea aquatic, were the most contaminated plants. Sauropus androgynous tended to be accumulated higher Cd (10.8 mg/kg) while Ipomoea aquatic was accumulated more Pb (17.3 mg/kg). Health impact monitoring revealed that Cd and Pb concentrations in hair samples were up to 0.93 and 84.2 mg/kg, respectively. Consumption of vegetables would lead to potential health risks especially for children, since the values of HQ of Cd and Pb for vegetables would sum up to almost 1. Thus, long-term Cd and Pb exposure by regular consumption of locally grown vegetables poses potentially health problems to the local population.
SOURCE APPORTIONMENT OF VOCS BY RECEPTOR MODELLING IN AN URBAN SITE IN HA NOI
Authors: Nhu Ngoc Do Thi
Published: August 2018

Volatile organic compounds (VOCs) are atmospheric pollutants of concern because of the health effect including carcinogenic risk of some of their species and the contribution in the formation of tropospheric ozone. The levels of VOCs in Hanoi were demonstrated to be higher than neighboring countries by previous research. The ozone potential formation (OFP) of VOCs was also some folds higher than others. Among transportation sources, VOCs were proved to be mainly emitted from motorbikes. The contribution percentages of transportation and other sources such as industrial, biomass burning sources are still remained unknown. In this research we applied chemical mass balance (CMB) receptor modelling to determine VOCs source apportionment. One week VOCs observation data at Hanoi University of Science and Technology in June 2017 was applied for investigation. Fourteen VOC species among 55 of which were applied for CMB modelling. Transportation and biomass burning source profiles were developed by monitoring in this study. Four other source profiles, namely gasoline evaporation, industrial production, cooking and paint that were compiled or calculated from previous studies. The results showed that the main sources of VOCs were vehicular emission, biomass burning, and gasoline evaporation contributing 37 %, 21 % and 20 % for VOCs levels, respectively. Other sources contributed for the leftover. The results can support to initiate policy for future control of VOCs.

The objective of this article is to review topography of posterior superior alveolar artery (PSAA), and to present a case with visualization of a rare anatomic variation of PSAA. An electronic search was undertaken to identify articles about topography of PSAA in Medline, Embase, and Google Scholar databases, published between January 1977 and December 2017. Two animal studies, 8 cadaver studies, 18 cone-beam computerized tomography (CBCT) studies, and 2 review articles were found. The animal studies, cadaver studies, and review articles were excluded because they were not about topography of PSAA. Only CBCT studies were included in this review. Accurate knowledge of vital structures in the surgical area is critical during surgical procedures. PSAA should be analyzed during planning sinus lifting with lateral approach. In the present case, a detailed evaluation of patient by CBCT provided the opportunity to find out a rare variation of PSAA with multiple vessels.

No Recourse to Social Work? Statutory Neglect, Social Exclusion and Undocumented Migrant Families in the UK
Authors: Jolly Andy
Published: August 2018

Families in the UK with an irregular migration status are excluded from most mainstream welfare provision through the no recourse to public funds rule, and statutory children’s social work services are one of the few welfare services available to undocumented migrant families. This article draws on semi-structured interviews with undocumented migrant families who are accessing children’s services support to illustrate the sometimes uneasy relationship between child welfare law and immigration control. Outlining the legislative and policy context for social work with undocumented migrant families in the UK, the article argues that the exclusion of migrant families from the welfare state by government policy amounts to a form of statutory neglect which is incompatible with the global social work profession’s commitment to social justice and human rights.
Destructive and Non Destructive Strength Evaluation of Concrete Exposed to Fire
Authors: Abdulkadir Mohamad , Karim Atta , Abdullah Avin
Published: August 2018

In this investigation concrete of different compressive strength is exposed to fire for various duration similar to natural fire occurring in buildings. A total of 72 Concrete cubes have been cast from three different concrete mixes then exposed to fire up to 10000C for three different durations (15,30 and 60 minutes) then tested using non- destructive methods like hammer rebound test and Ultra-Sonic Pulse velocity test. Then  the cubes were tested to destruction to measure their compressive strength. The results have shown that the unit weight, compressive strength and actual residual strength decreases with the increase of firing exposure duration similar to concrete exposed to steadily rising temperature. The correlation between the cube compressive strength and RN of the hammer test is very close, however the correlation coefficient of the cube strength with the UPV results is less. Using the combined method of the NDT, the relation between the cube strength and the NDT improves. Equations of relation betweencompressive strength and NDT tests are proposed for use in practice.

Published: August 2018

Pigeons are very well adapted and proliferate without control in urban centers. In this current study, ectoparasites and haemoparasites of 140 adult domestic pigeons (Columba livia domestica) of both sexes were studied, from different localities in Sulaimani province during April to October 2014, since there is no enough data regarding the frequency and identification of ectoparasites and haemoparasites in domestic pigeons in Sulaimani province. All pigeons were examined for the presence of ectoparasites and haemoparasites through checking of blood samples using Giemsa stain. As a result, various species of ectoparasites and haemoparasites were observed. From which, 4 species of lice were detected named Columbicola olumbae (62.5%) followed by Hoborstiella lata (10.42%), Campanulotes compar (4.17%) and Menacanthus stramineus (3.13%). On the other hands, 19.79% of infected pigeons with ectoparasites were diagnosed with the presence of more than 1 lice species. Additionally, examined Giemsa stained smears showed that 55.72% of studied pigeons were harbor haemoparasites including Haemoproteus species (28.20%) followed by Plasmodium species (26.92%) and then Leucocytozoon species (11.53%) consequently.

Authors: Strizhakov A. N. , Timokhina Е. V. , Ibragimova S. M. , Belousova V. S. , Martirosyan Ya. O.
Published: August 2018

In the present review, a new approach to studying the pathogenesis and predicting the development of preeclampsia (PE) – namely, the determination of matrix metalloproteinases (MMPs) – is discussed. Currently, the major cause of PE is thought to be an incomplete remodeling of spiral arteries because of an insufficient number of invading cytotrophoblasts or the absence/inactivation of crucial lysing enzymes, i.e. matrix metalloproteinases. The role of MMP-1, MМP-2, MМP-3, MМP-7, MМP-9 in the placenta formation, the development of oxidative stress and endothelial dysfunction is described. We propose that in the future, the MMPs may be used for differentially predicting early and late PE.

Bu çalışma Türkiye’de 1981-2014 döneminde nüfus
yoğunluğu, yenilenebilir enerji tüketimi, finansal gelişme, gelir ve karbon (CO2)
salımı arasındaki ilişkilerin çevresel Kuznets eğrisi (ÇKE) hipotezi kapsamında
incelenmesini amaçlamaktadır. ARDL sınır testi ile tahmin edilen uzun dönem
katsayıları nüfus yoğunluğu, finansal gelişme ve ekonomik büyümenin CO2
salımını arttırdığını, alternatif enerji tüketiminin ise çevre kalitesi
üzerinde pozitif bir etkiye sahip olduğunu göstermektedir. Bu çalışmanın
sonuçları ayrıca ÇKE hipotezinin Türkiye için geçerli olduğunu belirtmektedir.
Ancak 12,421$ olarak belirlenen dönüm noktası analiz dönemindeki en yüksek kişi
başına düşen gelir düzeyinin üzerinde yer almaktadır. Bu nedenle Türkiye’de
gelir düzeyi arttıkça CO2 salımı da artmaya devam etmektedir. Yenilenebilir enerji tüketiminin bir göstergesi olarak
kullanılan karbonhidrat içermeyen enerji tüketimi, Türkiye için CO2
salımını azaltmada alternatif bir çözüm olabilir.
Intersetorialidade e o trabalho em equipe: casos de estudo do Brasil e da Itália
Authors: Silocchi Cassiane , Junges José Roque , Ardigò Martino
Published: August 2018

Dois casos de estudo na atenção primária que se destacam na criação de estratégias para o enfrentamento das Doenças Crônicas Não Transmíssiveis (DCNT), podem ser observados no Brasil e na Itália: a experiência do Serviço de Saúde Comunitária que integra o Grupo Hospitalar Conceição no Brasil e a Unidade Sanitária Local de Ferrara que integra o Serviço Sanitário Regional da Emilia Romagna na Itália. Tendo em vista estes dois casos, este estudo tem como objetivo evidenciar e problematizar similaridades e diferenças entre os contextos no que se refere a estratégias relacionadas à organização do cuidado às condições crônicas. A metodologia utilizada foi prioritariamente qualitativa, uma vez que se se baseou em leituras, análises documentais e observações. Colocando em análise os dois casos, observou-se que ambos apresentam propostas significativas, contudo, ainda identificam-se problemáticas em relação ao trabalho em equipe e a intersetorialidade. No caso italiano, merece destaque a intersetorialidade como estratégia ainda em construção, bem como a falta de uma cultura de trabalho em equipe e a cogestão fragmentária, em que os médicos se colocam fora do sistema. No caso brasileiro, ao contrário, existe trabalho em equipe, contudo, o ato de trabalhar com novas estratégias, gera certo desconforto na equipe. Em relação a intersetorialidade, há iniciativas para ações intersetoriais, contudo, ainda existem barreiras para a sua aplicabilidade. Conclui-se que a implementação de um novo modelo assistencial, voltado para as DCNT, necessi­ta ainda ser assimilado no cotidiano dos serviços de saúde, pelos profissionais/equipes de saúde e pe­los gestores da saúde.
Análise do financiamento da Política Nacional para a Atenção Básica de 1996 até 2017
Authors: Pinto Hêider Aurélio
Published: August 2018

O artigo utiliza o referencial da análise de política para estudar as principais ações da Política Nacional para a Atenção Básica, tomando como elemento de análise a expressão das mesmas no orçamento federal de 1996 até 2017. Este estudo descritivo-analítico fez uso da análise documental de relatórios, sistemas de informação, sites e normativas relacionadas com o orçamento federal e que disciplinaram cada uma das ações estudadas. O estudo descreveu o desenho, as mudanças essenciais e a evolução da alocação dos recursos relacionando-os com os objetivos e prioridades da política. Identificou que os modos de repassar os recursos é parte central da estratégia dessa política ao mesmo tempo que reproduz o modelo centralizado do federalismo brasileiro e entra em contradição com o princípio descentralização do Sistema Único de Saúde. Ao fim, se discute os achados mais importantes e reflete sobre as perspectivas ante o cenário atual.
Identification of Mechanism and Pathway of the Interaction between the African Traditional Medicine, Sutherlandia Frutescens, and the Antiretroviral Protease Inhibitor, Atazanavir, in Human Subjects Using Population Pharmacokinetic (PK) Analysis
Authors: Muller Adrienne Carmel , Ducharme Murray P , Kanfer Isadore
Published: August 2018

Although the use of the indigenous Southern African plant, Sutherlandia frutescens (SF) for the treatment of HIV/AIDS has previously been described, the risk which it may pose to the safety and efficacy of ARVs and the potential mechanisms which underlie such effects may have clinical significance and relevance. The protease inhibitor (PI), atazanavir (ATV) is a substrate of the efflux transporter, P-gp which modulates absorption in the small intestine, as well as CYP3A4 and CYP3A5enzymes which facilitate metabolism in the small intestine and liver. The objective of this study was to investigate the effect of SF on the pharmacokinetics (PK) of atazanavir (ATV) and to use a population PK analysis to fit and explain plasma concentration vs. time profiles of ATV generated in a previously conducted study in healthy male subjects in order to understand and postulate on the potential mechanism(s) of the drug-drug interaction. The population PK Compartmental Analysis of ATV before and after a two-week regimen of Phyto Nova Sutherlandia SU1 tablets which contain SF plant material indicated that a two compartment model with a dual absorption mechanism best explained the data. The dual absorption mechanism is hypothesized to reflect “passive” (first-order, Ka parameter) and “active” (zero-order, K0 parameter) absorption processes. The model suggested that the mechanism by which SF reduced the overall bioavailability of ATV may be modulated via the inhibition of the “active” absorption process. This study has highlighted the utility of population PK analyses in postulating probable mechanism(s) whereby an ATM or a herbal medicine interacts with an allopathic drug.
Kalendarium życia kulturalnego Łodzi (cz. 2) 1–15 kwietnia 1945
Authors: Dakowicz Przemysław
Published: August 2018

Publikacja niniejsza, drugi fragment Kalendarium łódzkiego życia kulturalnego w latach 1945–1946, obejmuje swoim zakresem pierwszą połowę kwietnia 1945 roku, czas organizowania się kultury po przeszło pięciu latach niemieckiego terroru okupacyjnego. W dziejach miasta przełom zimy i wiosny roku 1945 był to okres szczególny – wobec niemal całkowitego zburzenia Warszawy przez Niemców, na terenie Łodzi ulokowały się niektóre spośród komunistycznych urzędów, zaczęli tu także zjeżdżać ważni przedstawiciele życia umysłowego i kulturalnego. Oferowano im mieszkania, pracę w dynamicznie rozwijającej się, kontrolowanej przez władzę prasie oraz w tworzonych naprędce instytucjach kultury i uczelniach. Autor tekstu próbuje – poprzez szczegółową denotację faktów z pogranicza historii, polityki, życia umysłowego i artystycznego – przedstawić mechanizmy i dynamikę najwcześniejszego etapu kulturowo-ideologicznej rewolucji przeprowadzonej w Polsce w latach 1945–1948.

Authors: Putra Sukarman Hadi Jaya
Published: August 2018

The purpose of this study was to determine the effect of supplementation of turmeric powder (Curcuma longa L.) before mature sex to the level of High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) serum quail of Japan (Coturnix coturnic japonica L.). This study uses an experimental method with completely randomized design pattern. The test animal used is 45 female Japanese quail of female divided into 3 groups, namely; P0: Japanese quail that is not given turmeric powder, P1: Japanese quail given turmeric powder with dose 54 mg/quail/day, P2: Japanese quail given turmeric powder with dose 108 mg/quail/day. Each group consists of 5 repetitions. Levels of HDL and LDL serum were taken at the Japanese quail. The data obtained were analyzed uses analysis of variance (ANOVA) and continued with Duncan test with 95% confidence interval (α = 0.05). The result showed that the powder of turmeric before genital effect (P˂0.05) increased the HDL level and decreased the LDL level of Japanese quail. Provision of turmeric powder at dose of up to 108 mg/quail day were relatively higher raising serum HDL levels and relatively higher lowering LDL levels of Japanese quail.
