Published: April 2019

Abstract
Generally, the strength at the weld line of the injection molded part is very weak. The heat transfer coefficient (HTC) between the polymer melt and the mold cavity surface was analyzed to solve this problem. The surface roughness of the mold cavity and the material of the mold insert were changed to adjust the interface environment between the polymer melt and the mold cavity surface. HTC was obtained by combing the experimental measurement with the theoretical calculation. In the current study, the influence of HTC on the tensile strength of the weld line of the molded specimen was investigated. The results show that the weld line strength of the molded specimen increases with the decrease in HTC between the polymer and the mold cavity surface. Meanwhile, the decrease in the surface roughness of the mold cavity or replacing the mold material with lower thermal conductivity can reduce the value of the HTC between the polymer and the mold effectively and can delay the cooling rate of the hot polymer melt. This provides a new idea to solve thin-wall injection molding weld line defects.

Abstract
The present work was devoted to study of sorption parameters of resorcinol-formaldehyde resins synthesized through introduction of an inorganic filler (in amounts of 10 and 25 wt.%) with its subsequent leaching. The surface morphology and composition of ion-exchange resins have been investigated by means of the method of scanning electron microscopy. The effect of internal diffusion on the peculiarities of the ion-exchange process has been determined. It has been revealed that the ion-exchangers destruction upon a prolonged contact with highly alkaline solutions is followed by the decrease of internal diffusion coefficients and selectivity toward Cs-137 micro-quantities. The sorption properties of resins under dynamic conditions at high solution feeding rates have been studied. A sample with the highest efficiency of Cs-137 removal from highly mineralized solutions has been identified.
Zur Autonomie indirekter Redewiedergabe – Eine diachrone Perspektive
Authors: Demske Ulrike 
Published: April 2019

AbstractRegarding verbal mood and complementation patterns of reporting verbs, the distinction between direct and indirect reported speech is well established in present-day German. This paper looks into the history of German: Common knowledge has it that both the use of verbal mood as well as the quality of clause linkage undergo considerable changes giving rise to the question how these changes affect the manifestations of indirect reported speech in earlier stages of German. The historical record of the 16th century (with an outlook on the 17th century) shows that the distinction between direct and indirect reported speech is not yet grammaticalized in historical sources at the time. In particular with respect to dependent (in)direct reported speech, both types prefer V2-complements with only verbal mood differentiating between the types. Although present and past subjunctive have a much wider distribution in earlier stages of German, the occurrence of free indirect speech likewise testifies to its increasing use as a marker of indirect reported speech. The growing conventionalization of patterns of indirect reported speech in the course of Early Modern German may be considered as an example for an increase of subjectification in its development.
Redewiedergabe – Schritte zur automatischen Erkennung
Authors: Brunner Annelen 
Published: April 2019

Abstract
This contribution presents a quantitative approach to speech, thought and writing representation (ST&WR) and steps towards its automatic detection. Automatic detection is necessary for studying ST&WR in a large number of texts and thus identifying developments in form and usage over time and in different types of texts. The contribution summarizes results of a pilot study: First, it describes the manual annotation of a corpus of short narrative texts in relation to linguistic descriptions of ST&WR. Then, two different techniques of automatic detection – a rule-based and a machine learning approach – are described and compared. Evaluation of the results shows success with automatic detection, especially for direct and indirect ST&WR.

Published: April 2019

Structural, electrokinetic and energy state characteristics of the Zr1-xVxNiSn semiconductive solid solution (х=0–0.10) were investigated in the temperature interval 80–400 К. It was shown that doping of the ZrNiSn compound by V atoms (rV=0.134 nm) due to substitution of Zr (rZr=0.160 nm) results in increase of lattice parameter а(х) of Zr1-xVxNiSn indicating unforecast structural change. Based on analysis of the motion rate of the Fermi level ΔεF/Δх for Zr1-xVxNiSn in direction of the conduction band it was concluded about simultaneous generation of the structural defects of the donor and acceptor nature (donor-acceptor pairs) by unknown mechanism and creation of the corresponding energy levels in the band gap of the semiconductor.

The photoconductivity spectra in the temperature range T≈36-200 K and the spectra of thermostimulated currents in the temperature range T≈70-300 K of Tl1-xIn1-xSnxSe2 single crystals obtained by directional crystallization of Bridgman-Stockbarger have been studied. The induced photoconductivity and long-term photoconductivity relaxation processes have been found. To interpret the found results, a model of two-center recombination has been suggested. It is illustrated that the role of the r-centers of slow recombination are formed by Tl vacancies. On the basis of the studies of the spectra of thermally stimulated currents, the thermal energy of electrons activation with t-levels of adhesion has been determined.

Based on the results of X-ray structural analysis, changes in the crystalline structure that occurred during 15 years in surface layers of epitaxial films of iron-yttrium garnet implanted by B+ ions were studied. The processes that occur during the B+ ion implantation of in ferrite-garnet films, and the processes that accompany the low-temperature aging of ion-implanted films are considered. Strain profiles were determined from the experimental rocking curves, obtained immediately after ion implantation and after 15 years. It was found that the value of relative maximum deformation of surface layers decreases at constant thickness of the disturbed layer.

OBJECTIVES:
To compare medical and developmental outcomes over the first 2 years of life in extremely preterm infants with bronchopulmonary dysplasia (BPD) who were discharged on supplemental oxygen via nasal cannula with outcomes of infants with a similar severity of respiratory illness who were discharged breathing in room air.

METHODS:
We performed a propensity score–matched cohort study. Eligible infants were born at &lt;27 weeks’ gestation, were receiving supplemental oxygen or respiratory support at 36 weeks’ postmenstrual age, and were assessed at 18 to 26 months’ corrected age. Study outcomes included growth, resource use, and neurodevelopment between discharge and follow-up. Outcomes were compared by using multivariable models adjusted for center and age at follow-up.

RESULTS:
A total of 1039 infants discharged on supplemental oxygen were propensity score matched 1:1 to infants discharged breathing in room air. Infants on oxygen had a marginal improvement in weight z score (adjusted mean difference 0.11; 95% confidence interval [CI] 0.00 to 0.22), with a significantly improved weight-for-length z score (adjusted mean difference 0.13; 95% CI 0.06 to 0.20) at 22 to 26 months’ corrected age. Infants on oxygen were more likely to be rehospitalized for respiratory illness (adjusted relative risk 1.33; 95% CI 1.16 to 1.53) and more likely to use respiratory medications and equipment. Rates of neurodevelopmental impairment were similar between the groups.

CONCLUSIONS:
In this matched cohort of infants with BPD, postdischarge oxygen was associated with marginally improved growth and increased resource use but no difference in neurodevelopmental outcomes. Ongoing and future trials are critical to assess the efficacy and safety of postdischarge supplemental oxygen for infants with BPD.

Published: April 2019

Background and purpose: Malaria is a public health problem in Eastern Indonesia, especially in East Nusa Tenggara. Insecticide-treated bed net was massively distributed in 2014, however the incidence of malaria in Ende District remains high. This study aims to examine association between the use of insecticide-treated bed net and malaria infection.Methods: A case control study was conducted in Wewaria Subdistrict, Ende District in 2016 involving 67 cases and 134 controls. Data on the use of insecticide-treated bed net which include methods of net use, net use practice, net maintenance and its current conditions were obtained through interviews and observations. Physical conditions of respondentâ€™s house that include conditions of the wall, floor, window, ventilation, ceiling and lighting were also documented through observations.Â Data were analysed using logistic regression.Results: Cases and control groups were comparable for gender (p=1), age (p=0.9), education level (p=0.9) and occupation (p=0.6). This study found that five variables were associated with malaria infection: irregular use of the insecticide-treated bed net (AOR=4.08; 95%CI: 1.87-8.89), torn net (AOR=2.23; 95%CI: 1.10-4.54), inadequate lighting (AOR=3.64; 95%CI: 1.77-7.47), humid floor (AOR=3.02; 95%CI: 1.24-7.34) and holes or broken ceiling (AOR=2.41; 95%CI: 1.02-5.72).Conclusions: The use of insecticide-treated bed net and physical conditions of the house are risk factors for malaria infection.

Published: April 2019

Background and purpose: HIV testing among pregnant women can reduce the risk of mother to child HIV transmission. The implementation of prevention of mother to child transmission (PMTCT) program in Bangli District is suboptimal. This study aims to explore challenges and opportunities for implementing PMTCT program from both user and provider perspectives.Methods: A qualitative approach was conducted in Bangli District between April and May 2016. Data were collected using in-depth interviews with 18 informants. All informants were purposively selected and covered of 10 pregnant women, two counsellors, two laboratory analysts, two head of community health centres, one disease control officer from Bangli District Health Office and one officer from Bangli District AIDS Commission. Data were analysed using thematic method.Results: Pregnant women chose to have ANC service at private midwife and obstetrician instead of Â public health centre. From health providersâ€™ perspectives barrier of PMTCT implementation included lack of health human resources and a high level of stigma and discrimination related to HIV/AIDS in the community. This study revealed that there was an opportunity for PMTCT implementation in Bangli District due to positive attitudes and supports from husband and health provider toward HIV testing. Another opportunity is to involve village health cadres and community leaders in promoting HIV testing among pregnant women.Conclusions: Implementation of PMTCT program in health centre should include network of private practitioner and enhance village health cadresâ€™ and community leadersâ€™ participation.
