Background: K4 is the fourth prenatal check-up visit for health workers to obtain antenatal care according to standards and to detect complications as early as possible during pregnancy. The K4 coverage in Batang-Batang Daya village, the working area of ​​the Batang-Batang Puskesmas is still below the target in 2018. The purpose of this study was to determine the relationship between husband's support and the decision of pregnant women in carrying out K4 examinations. Methods: The design of this study is analytic correlational with a cross-sectional study approach, the population of pregnant women in the third trimester of pregnancy in Batang-Batang Daya Village in 2019 was 27 respondents, using total sampling techniques, husband's support data was collected using a valid and reliable questionnaire. K4 examination data used a checklist in the KIA book, and the statistical test used was Chi-Square with an expected value of less than 5. Result: The results showed that most of the pregnant women received support from their husbands as many as 20 people (74.1). Most of the pregnant women underwent a K4 examination (4th pregnancy visit), as many as 20 people (74.1%). The analysis result from the Chi-Square test shows the value (ρ) = 0.000. Conclusion: It can be concluded that the husband's support is related to the decision by pregnant women to carry out K4 examinations. Husbands should always provide support to their wives to carry out routine checks so that pregnant women are motivated to carry out K4 examinations, and are more confident about carrying out their pregnancy.

Published: September 2020

Background: Midwife students are at risk of anemia, due to their busy life on campus and the influence of technology and modernization, thus ignoring the nutritional problems of the food they consume. Midwife students will later provide services to mothers and children so that sufficient knowledge is needed about health and healthy conditions without anemia. The purpose of this study was to determine the relationship between attitude and knowledge of midwife students to prevent anemi. Methods: analytical survey research type with cross sectional approach with a total sampling of 132 students of the Midwifery Study Program at the Blora Poltekkes Ministry of Health, Semarang.  The research was conducted in September 2019 and data were collected by distributing questionnaires directly to students. Data analysis using Chi square. Results: There was a significant relationship between knowledge and efforts to prevent anemia with p value = 0.001 <0.05. However, there is no significant relationship between attitudes and efforts to prevent anemia p value = 0.164> 0.05. Good knowledge about anemia will be able to encourage these students to take preventive measures. Meanwhile, students who have a positive attitude towards anemia prevention efforts do not necessarily make efforts to prevent anemia due to economic and lifestyle factors. Conclusion: Midwife student knowledge related to efforts to prevent anemia and can be improved by providing more intense information with attractive media to midwife students. Meanwhile, attitude is not related to preventing anemia.

The topic is mostly written in the Turkish language so we will be focusing on such references.
İslam Hukuk Usulünde Müşterek Lafzın Manaya Delaletine Dair Tartışmalar
Authors: SAMAR Mahmut
Published: September 2020

Kitap ve sünnet İslam hukukunun tarihi süreç içerisinde metin halini almış iki temel kaynağıdır. Bu iki kaynakta yer alan nasları anlamak ve bunun için doğru bir yöntem belirlemek İslam hukuk usulünün en önemli konularından biridir. Fıkıh usulünde lafızlar (elfâz) bahsi bu anlamda ihtiyaç duyulan kuralları içeren önemli bir bölümdür. Fıkhî anlamdaki ihtilafların çoğu nasları inşa eden lafızlara yüklenen manalara ve bu manalardan elde edilen hükümlere dayanır. Çünkü lafızlar (elfâz) bahsi, naslardan hüküm çıkarmada ihtiyaç duyulan kuralları ihtiva eder. Bu nedenledir ki fıkıh usulü alanında kaleme alınmış eserlerde lafızlara genişçe yer verildiği görülür. Lafızlar, farklı açılardan taksime tabi tutularak incelenir. Bu çerçevede dört kategoride yirmi dört lafız üzerinde titizlikle durulmaktadır. Çünkü lafızların tasnifi, birbiriyle ilişkisi, hiyerarşisi bilinmeden nasların doğru bir şekilde anlaşılması oldukça güçtür. Söz konusu taksime göre ilk sırada “vaz‘ olunduğu mana bakımından lafızlar” yer alır. Kapsadığı mana bakımından veya şümul bakımından lafızlar olarak da bilinen bu kate-goride dört lafız türü bulunur. Bunlar; âm, hâs, müşterek ve müevvel lafızlardır. Bun-lardan hâss lafız ise emir, nehiy, mutlak ve mukayyed kısımlarına ayırılır. İkinci sırada kullanıldığı mana bakımından lafızlar incelenir. Bu grupta hakikat, mecaz, sarih ve kinaye lafızları yer alır. Üçüncü olarak manaya delaletinin açık veya kapalı olması bakımından lafızlar ele alınır. Bunlar; dördü açık, dördü de kapalı olmak üzere sekiz lafızdan oluşur. Açık lafızlar; zahir, nass, müfesser ve muhkem. Kapalı lafızlar; hafî, müşkil, mücmel ve müteşabih. Son sırada manaya delaletinin şekli bakımından lafızlar üzerinde durulur. Bu lafızlar da ibarenin delaleti, işaretin delaleti, nassın delaleti ve iktizanın delaleti olmak üzere dört kısımdır. Bu taksim Hanefî/fukahâ metodunu be-nimseyen usûlcülere aittir. Mütekellimin/Şâfiî usûlcüleri de bu lafızları incelemişlerdir. Ancak iki yöntem arasında taksimde, sıralamada vs. bazı farklar söz konusudur.

Canine Myiasis and its Causal Agents in India
Authors: Singh A
Published: September 2020

Myiasis, the invasion of tissues of live humans and vertebrate animals with dipteran larvae is common throughout the tropical regions of the world. It is a real welfare problem of worldwide distribution and a matter of great concern among medical and veterinary fields. The reports indicate that dogs are the most common canine species affected by myiasis. The present study was conducted to ascertain prevalence of myiasis among pet dogs and to identify myiasis-causing flies in India. The study resulted in the identification of three species of myiasis causing flies among pet dogs. The Old World Screw-worm fly- Chrysomya bezziana was reported to be the predominant fly species followed by Musca domestica and Sarcophaga ruficornis. The overall infestation rate was high in rainy season followed by summer, spring, autumn and least in winter. Incidence of myiasis was found to be higher among adult males than the females. The most frequently infested body regions were the face, neck and perianal region among males and face, neck and vulvar lips among females. Most infestations were found in the wounds at front body parts of the adult males, suggesting the common occurrence of myiasis in consequence of competitive fighting.

CHALLENGES OF CIVIC ENGAGEMENT IN THE (POST-SOCIALIST) TRANSITIONAL SOCIETY: EXPERIENCES FROM WATERFRONT URBAN AREAS MEZAPARK IN RIGA AND KALARAND IN TALLINN
Authors: Prilenska Viktorija , Paadam Katrin , Liias Roode
Published: September 2020

Current case studies examine the shortcomings of civic engagement strategies during the design process and ratification of detailed plans for urban areas of strategic importance − Mezapark in Riga and Kalarand in Tallinn. Detailed plans caused public outcries and led to long-lasting and distressful negotiations between local communities, developers, designers and municipalities over the future development and use of these areas. The debates about detailed plans raised an increasing public interest in planning related issues and growing demands for greater civic engagement in decisions shaping the city. At the same time, the debates demonstrated the inability of local planning frameworks to meet public expectations. There appears a salient need for changing the planning culture. This paper studies the shortcomings of civic engagement strategies and the desirable changes through a series of semi-structured interviews with key stakeholders involved and the analysis of planning related documentation.
Astraea: Predicting Long Rotation Periods with 27 Day Light Curves

Published: September 2020

The rotation periods of planet-hosting stars can be used for modeling and mitigating the impact of magnetic activity in radial velocity measurements and can help constrain the high-energy flux environment and space weather of planetary systems. Millions of stars and thousands of planet hosts are observed with the Transiting Exoplanet Survey Satellite (TESS). However, most will only be observed for 27 contiguous days in a year, making it difficult to measure rotation periods with traditional methods. This is especially problematic for field M dwarfs, which are ideal candidates for exoplanet searches, but which tend to have periods in excess of the 27 day observing baseline. We present a new tool, Astraea, for predicting long rotation periods from short-duration light curves combined with stellar parameters from Gaia DR2. Using Astraea, we can predict the rotation periods from Kepler 4 yr light curves with 13% uncertainty overall (and a 9% uncertainty for periods >30 days). By training on 27 day Kepler light-curve segments, Astraea can predict rotation periods up to 150 days with 9% uncertainty (5% for periods >30 days). After training this tool on these 27 day Kepler light-curve segments, we applied Astraea to real TESS data. For the 195 stars that were observed by both Kepler and TESS, we were able to predict the rotation periods with 55% uncertainty despite the wild differences in systematics.
BVRCIC Observations and Analysis of the UV LEO-type Binary, the Pre-WUMa, V1023 Persei
Authors: Samec Ronald , Caton Daniel , Faulkner Danny R. , Morgan Shannon
Published: September 2020

V1023 Per is a polar spotted, but well-detached dwarf binary, very likely a Pre-WUMa eclipsing binary. It was observed on 11 nights in 2015 October, November, and December at Dark Sky Observatory in North Carolina with the 0.81 m reflector of Appalachian State University. The period behavior is complex and may be increasing with a cubic or quadratic ephemeris. Its odd light curves are of high amplitude but have no totality and reach maximum light just before and following the secondary eclipse, indicating that it has polar spots similar to UV Leo. The 28 yr orbital period study calls the attention of observers to further monitor this binary to understand the complex nature of the period evolution. Its presently fixed polar spot does indicate that it must have a strong magnetic field and that it is synchronously rotating. The BVR
c
I
c simultaneous 2016 Wilson–Devinney program (W-D) solution gives fillouts of 68% and 75% for the primary and secondary components, respectively. The polar position of the spot, its radius (24°), and T-fact (0.75) indicate that a strong magnetic field is present. The small ΔT in the components (∼289 K) show that the stars are similar in spectral type despite them being well detached. The inclination is high, ∼85.°19 ± 0.°04, but there is not a total eclipse due to the high mass ratio (∼0.739 ± 0.001). Due to the low galactic position (longitude = 150.°390, latitude = −1.°023), its reddening is addressed. The primary components temperature is estimated to be 5250 ± 250 K.
The Ubiquity of AGN Winds in Seyfert 1 Galaxies at Low Redshift

Published: September 2020

The optical spectra of 3896 Seyfert 1 (Sy1) galaxies detected with WISE at z < 0.4 were analyzed for evidence of outflows. In 37% of the Sy1s in our sample, the outflows appear as broad, blue-shifted, spectrally resolved components of the [O iii]λ5007 Å emission line, with a mean maximum velocity V
max ∼ 1014 km s−1 that is consistent with AGN winds. For each Sy1, we deduced the black hole (BH) mass, bolometric luminosity, Eddington ratio, and power-law index of the continuum, which we compared with the star formation rate (SFR) and host morphology. Having separated our sample in two spectroscopic subgroups—Sy1s with only broad Balmer lines (Sy1B) and those with both narrow and broad (Sy1N) lines—and distinguishing those that show as outflow (Sy1Bw and Sy1Nw), we report the following differences: (1) the BH mass is systematically higher and the power-law steeper in the Sy1B–Sy1Bw than in the Sy1N–Sy1Nw; (2) V
max is higher in the Sy1Bw than in the Sy1Nw, correlated in both groups with the BH mass and bolometric luminosity; (3) the Eddington ratio and SFR are higher in the Sy1 with outflows; and (4) the specific star formation rates (sSFRs) of the Sy1s are normal for their morphology and mass, typical of early-type spiral galaxies in the green valley, far from the quenched regime. From these results, we conclude that AGN winds in Sy1s are triggered by higher accretion rates and probably radiatively launched, and there is no clear evidence of an effect on the star formation.
Submerged Sources of Transient Acoustic Emission from Solar Flares

Published: September 2020

We report the discovery of ultra-impulsive acoustic emission from a solar flare, emission with a seismic signature that indicates submersion of its source approximately a Mm beneath the photosphere of the active region that hosted the flare. Just over two decades ago V. V. Zharkova and A. G. Kosovichev discovered the first acoustic transient released into the Sun’s interior by a solar flare. These acoustic waves, refracted back upward to the solar surface after their release, make conspicuous Doppler ripples spreading outward from the flaring region that tell us a lot about their sources. The mechanism by which these transients are driven has stubbornly eluded our understanding. Some of the source regions, for example, are devoid of secondary Doppler, magnetic, or thermal disturbances in the outer atmosphere of the source regions that would signify the driving agent of an intense seismic transient in the outer atmosphere. In this study, we have applied helioseismic holography, a diagnostic based upon standard wave optics, to reconstruct a 3D image of the sources of acoustic waves emanating from the M9.3-class flare of 2011 July 30. These images contain a source component that is submerged a full Mm beneath the active-region photosphere. The signature of acoustic sources this deep in the solar interior opens new considerations into the physics that must be involved in transient acoustic emission from flares—and possibly of flare physics at large. We develop analogies to seismicity remotely triggered by tremors from distant earthquakes, and consider prospects of new insight into the architecture of magnetic flux beneath flaring active regions.

SNe Ia are likely the thermonuclear explosions of carbon–oxygen white-dwarf stars, but their progenitor systems remain elusive. A few theoretical scenarios for the progenitor systems have been suggested, which have been shown to agree with some observational properties of SNe Ia. However, several computational challenges prohibit a robust comparison to the observations. We focus on the observed

Revision of the Plagiolepis schmitzii group with description of Pl. invadens sp. nov. – a new invasive supercolonial species (Hymenoptera: Formicidae)
Authors: Seifert Bernhard
Published: September 2020

Using high-resolution stereomicroscopy and exploratory data analyses, a taxonomic revision of the cryptic species close to Plagiolepis schmitzii Forel, 1895, called Pl. schmitzii group, was conducted. Morphology was numerically recorded under highly standardised conditions considering absolute size and 16 shape, pubescence and surface characters. A key to the non-parasitic Westpalaearctic species of the ant genus Plagiolepis Mayr, 1861 is provided which firstly separates, on species group level, the Pl. pygmaea (Latreille) species group, the Pl. pallescens Forel species group and the Pl. schmitzii species group and, finally, on species level, the cryptic species of the latter group. The recognised species of the Pl. schmitzii species group are Pl. schmitzii Forel, 1895 (invasive species), Pl. barbara Santschi, 1911, Pl. atlantis Santschi, 1920 and Pl. invadens sp. nov. (invasive species) that is described as new from a supercolony in Germany. Based on morphological arguments, the taxa Pl. barbara var. madeirensis Emery, 1921, Pl. maura polygyna Santschi, 1922 and Pl. schmitzii var. tingitana Santschi, 1936 are recognised as junior synonyms of Pl. schmitzii, the taxa Pl. schmitzii crosi Santschi, 1920, Pl. pallescens var. kabyla Santschi, 1920 and Pl. perperamusSalata et al., 2018 as junior synonyms of Pl. atlantis and the taxon Pl. maura Santschi, 1920 as junior synonym of Pl. barbara. A concluding comparative section suggests that pre-adaptations for anthropogenous dispersal and transformation to supercoloniality in introduction areas are apparently common traits in Plagiolepis ants.
The Effect of Length of Hospital Stay and Patient Factors on Patient Satisfaction in an Academic Hospital
Authors: Diwan Waqaar , Nakonezny Paul A. , Wells Joel
Published: September 2020

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) is a metric for patient satisfaction consisting of 19 questions divided into 10 domains. Scores affect hospital reimbursements and accreditation and may play a role in patient outcomes. It is unclear how length of stay and other factors affect each of the 10 domains. This retrospective review gathered data of 600 patients between December 2008 and January 2017 who completed the HCAHPS survey. The odds of complete satisfaction in each of the 10 domains was evaluated. The results suggest increased length of stay is associated with lower odds of patient satisfaction and decreased likelihood of recommending the hospital. The odds of being completely satisfied regarding communication with physicians, discharge information, and responsiveness of the hospital staff, as well as the odds of recommending the hospital to others, were lower if the care provider was younger than the patient. Obese patients were also more likely to be satisfied with responsiveness and care transition. Male patients were more satisfied with communication about medications (odds ratio [OR], 1.694), care transition (OR, 1.489), and cleanliness (OR, 2.120). Medicare and fewer consults were related to increased odds of patient satisfaction with care transition (OR, 1.748 and 0.573, respectively). Males, older patients, and White patients were more likely to recommend the hospital (OR, 1.476, 1.025, and 1.690, respectively). Length of stay affects patient satisfaction and likelihood of recommending the hospital to others. Other factors such as a younger provider age than the patient, lower body mass index, female sex, non-Medicare insurance, and higher number of consults are also associated with lower satisfaction in various domains. Hospital systems can bolster patient satisfaction by strategizing day-of-surgery and weekend staffing to reduce length of stay. [

Effects of Surgical Timing on Surgical Success and Long-term Motor and Sensory Outcomes of Infantile Esotropia
Authors: Muz Omer Ersin , Sanac Ali Sefik
Published: September 2020

Purpose:

To investigate the effect of surgical timing on long-term motor and sensory outcomes in patients with infantile esotropia.

Methods:

The medical records of patients who underwent strabismus surgery for infantile esotropia were reviewed retrospectively. The patients were divided into three groups according to age at the time of surgery: early group (6 to 11 months), late group (12 to 17 months), and very late group (18 to 27 months). The main outcome measures were final alignment, surgical success rate (the angle of deviation at final follow-up of ≤ 10 prism diopters [PD] of esotropia, no exotropia and no need for reoperation), stereoacuity, visual acuity, and the number of reoperations required during the follow-up.

Results:

A total of 79 patients (44 female, 35 male) met the inclusion criteria. The surgical success rate was 25.9%, 23.1%, and 53.8% in the three groups, respectively (
P
= .035). After a mean follow-up of 96 months, the average number of operations per child was 1.7 ± 0.9, 1.6 ± 0.6, and 1.4 ± 0.6 in the three groups, respectively (
P
= .020). The measurable stereopsis rate was higher in the early group (37% vs 3.8% and 3.8%, respectively) (
P
= .001). The amblyopia rate was similar between groups.

Conclusions:

The results show that performing surgery later in life in patients with infantile esotropia increases the motor success rate of surgery. In addition, orthophoria is achieved with fewer surgical operations. However, earlier surgery may improve stereopsis.

Skew doubled shifted plane partitions: Calculus and asymptotics
Authors: Han Guo-Niu , Xiong Huan
Published: September 2020

In this paper, we establish a new summation formula for Schur processes, called the complete summation formula. As an application, we obtain the generating function and the asymptotic formula for the number of doubled shifted plane partitions, which can be viewed as plane partitions "shifted at the two sides". We prove that the order of the asymptotic formula depends only on the diagonal width of the doubled shifted plane partition, not on the profile (the skew zone) itself. By using similar methods, the generating function and the asymptotic formula for the number of symmetric cylindric partitions are also derived.

We introduce a new family of dynamic mechanisms that restricts sellers from using future distributional knowledge. Since the allocation and pricing of each auction period do not depend on the type distributions of future periods, we call this family of dynamic mechanisms non‐clairvoyant.

We develop a framework (bank account mechanisms) for characterizing, designing, and proving lower bounds for dynamic mechanisms (clairvoyant or non‐clairvoyant). We use the same methods to compare the revenue extraction power of clairvoyant and non‐clairvoyant dynamic mechanisms.
Matching With Complementary Contracts
Authors: Rostek Marzena , Yoder Nathan
Published: September 2020

In this paper, we show that stable outcomes exist in matching environments with complementarities, such as social media platforms or markets for patent licenses. Our results apply to both nontransferable and transferable utility settings, and allow for multilateral agreements and those with externalities. In particular, we show that stable outcomes in these settings are characterized by the largest fixed point of a monotone operator, and so can be found using an algorithm; in the nontransferable utility case, this is a
one‐sided deferred acceptance algorithm, rather than a Gale–Shapley algorithm. We also give a monotone comparative statics result as well as a comparative static on the effect of bundling contracts together. These illustrate the impact of design decisions, such as increased privacy protections on social media, or the use of antitrust law to disallow patent pools, on stable outcomes.
Conmemoración estatal y representación escultórica del prócer de la Independencia peruana José Olaya (1823-1953)
Authors: Monteverde Sotil Rodolfo
Published: September 2020

El prócer peruano José Olaya fue un pescador indígena de modesta condición social, diferenciándose por ello de los demás próceres criollos extranjeros, militares y de situaciones económicas sosegadas, que encabezaron la Independencia peruana como José de San Martín y Simón Bolívar. Desde 1823, cuando Olaya fue fusilado por los españoles, cerca de la plaza Mayor de Lima, hasta cuando se cumplieron 130 años de su muerte, el Estado intentó primero homenajearlo con un lienzo (1823) y luego esporádicamente con un monumento público (en 1867, 1923 y 1952). Este texto analiza el contexto social y político en el cual se propusieron e inauguraron estas esculturas, qué sucedió con ellas y cómo fue representado Olaya.
¿Hacia un nuevo cristianismo? Religión y heterodoxia en la Joven Generación Argentina
Authors: Castelfranco Diego
Published: September 2020

El presente artículo analiza las concepciones religiosas de quienes integraron la Joven Generación Argentina a fines de la década de 1830. Dichos personajes pensaron a la religión, y más específicamente al cristianismo, como un vector de regeneración estrictamente terrenal sobre el cual debía apoyarse —junto a la filosofía— su proyecto de reforma social y política. Manifestaron también una velada hostilidad al catolicismo, asociado a las costumbres coloniales que se pretendía abandonar, a una España que consideraban “retrógrada” y a la “tiranía” de Juan Manuel de Rosas. Sus perspectivas religiosas no constituyeron un planteo sistemático, sin embargo, sino que es pertinente referir a ellas como dando forma a una “estructura de sentimientos”.
La Fundación Rockefeller y la Institución Cultural Española de Buenos Aires frente el exilio republicano español en la Argentina. El caso de Claudio Sánchez Albornoz
Authors: Lida Miranda
Published: September 2020

El exilio científico republicano en las Américas está ampliamente estudiado. En este contexto, el caso del historiador Claudio Sánchez Albornoz resulta excepcional, por la compleja estrategia puesta en marcha para su arribo a la Argentina. Fue apoyado por la Fundación Rockefeller (FR), cuyo papel ha sido poco estudiado. Otro actor que participó fue la Institución Cultural Española de Buenos Aires (ICEBA). Gracias a archivos de la Universidad de Buenos Aires, de la ICEBA (en correspondencia con la FR), podemos reconstruir la trama que lo llevó en la Argentina, con sostenido apoyo por parte de ambas instituciones.

Published: September 2020

The construction industry is one of the major producers of municipal solid waste. Although there are many studies in municipal solid waste management, the research on the recovery of recyclable building material from construction sites remains limited. This paper addresses the optimal design issue of the construction and demolition (C&D) waste logistics network based on the features of the construction industry from the contractors’ perspective. The purpose of this paper is to provide an optimal C&D waste recycling network decision (RND) model considering the change of construction sites location over time. A multi-period and multi-objective mixed-integer linear programming model was developed to minimize the cost of C&D waste disposal for contractors, and to minimize the carbon emissions from C&D waste transportation. An application study was conducted to assess the performance of the RND model. Through some sensitivity analysis experiments based on an immune genetic algorithm, the influences of environmental policies and carbon tax policy on improving the recycling rate of C&D waste and reduce the carbon emission were explored. The findings of this research suggest that: (1) a RND model with the feature of the construction industry developed in this paper can effectively optimize the C&D waste logistics network; (2) government policies and laws are valid political instruments to improve the recycling rate of C&D waste; (3) the carbon-tax analyses demonstrate that a carbon tax policy can effectively reduce carbon emissions.

A vast amount of construction and demolition (C&D) wastes are generated in Western Australia (WA) of which a major portion goes to landfills. The diversion of C&D waste from landfills would be the single most significant opportunity for WA to improve its recovery performance. C&D waste materials have already been investigated for their appropriateness and use in pavement and concrete. This work is the continuation of the authors’ previous work involving further experimental tests to prove the structural suitability of a building’s structural member (i.e., beam) made of recycled aggregates and industrial by-products. The concrete mixes considered in this study are 100NA+100 OPC (Control), 100RA+100OPC, 50RA+50NA+90OPC+10SF and 50RA+50NA+60OPC+30FA+10SF. The Reinforced Concrete (RC) beam made of 50RA+50NA+60OPC+30FA+10SF concrete mix was found to be the only eco-efficient option. This option has reduced the level of environmental impacts in a cost-competitive manner. The use of this eco-efficient option could also provide new employment opportunities and significant improvements in terms of land and energy resources conservation and bio-diversity enhancement.

The present study is aimed at investigated the miscibility in binary blend the Metallocene linear low density polyethylene (PE) and the Polypropylene homo (PP). Metallocene linear low density polyethylene is one of LLDPEs but with lower density higher melt flow index (MFI) than conventional LLDPE. The polyethylene and polypropylene blends (PB) were prepare by using o-xylene as solvent and polyethylene-co-glycidyl methacrylate (PE-co-GMA) as compatibilizer promote blending of immiscible homopolymers and the stability of the blend . The composites were characterized by wide angle X-ray diffraction (WAXD). Long period spacing was obtained using small angle X-ray scattering (SAXS).Crystallinity and melting behavior were studying by use the DSC and TGA, Metallocene linear low density polyethylene provide better behavior than the conventional LLDPE. The tensile test and DMA test were applied on the blends, which displayed improvement on the blend properties by using the PE-co-GMA and confirm the incompatible nature of the blends.

Published: September 2020

The series resistance (Rs) controls the device performance significantly and for organic diode, the typical value of Rs is quite high. There are not many reports on the investigation of the high value of resistance in organic diodes. In this paper, we report that the trapping of charge carriers which is an important parameter to control the charge transport mechanism in organic solids is responsible for this high value of series resistance. In this paper effect of trap energy on Rs has been studied in the presence of TiO2 and ZnO nanoparticles on Phenosafranine (PSF) dye-based organic diode. It is already reported that by incorporating nanoparticles, trap energy is reduced which in turn increases the conductivity and efficiency of the device. So it is expected that trap energy has a strong influence on Rs. In this work we have measured Rs by using the Cheung Cheung method and the trap energy is also measured by analyzing the dc current. The value of Rs is related to trap energy. The extracted values of Rs are about 250.8 KΩ, 108.0 KΩ, and 98.4 KΩ respectively for only PSF, PSF+ZnO, and PSF+TiO2. It is also been observed that by incorporating nanoparticles the trap energy is reduced. The estimated values of the trap energy are about 0.090eV, 0.078eV ,0.072eV respectively for only PSF, PSF+ZnO, and PSF+TiO2. It has been observed that lowering of trap energy by incorporating TiO2 and ZnO reduces the value of Rs.

The study results of the calcareous composites made with the use of activated mixing water are presented. Quicklime and slaked lime are used as lime binders. The mixing water was activated by the electric current and magnetic field in various modes. The effect of water activation on the physical and mechanical properties of slaked and quicklime composites and the resistance to the effects of the biological environment are studied. The water for mixing electromagnetic treatment effectiveness analysis is presented. The increase in the density of materials based on lime, trapped in activated water using ultrasound tests is proven. It was found that the mixing water activation affects the structure formation of composites and, under certain activation conditions, leads to an increase in such physical and mechanical parameters as strength and hardness. The positive effect of the mixing water activation on the lime-based materials’ resistance to microbial growth has been established, and the decrease in the growth of composites based on quicklime and slaked lime has been proved.
The Influence of Salts’ Presence in the Materials on their Moisture and Thermal Conductivity

Published: September 2020

Energy saving in buildings is largely determined by the energy efficiency of the external building envelopes. The latter, as a rule, are the multilayer and incorporate structural and heat-insulating layers. The presence of individual hygroscopic salts and their mixtures in building materials changes their physical and chemical properties. Due to the increase in the sorption properties of building materials and changes in the inter-pore substance composition, humidity increases and the heat-protective properties decrease. This paper presents the results of the experimental and theoretical studies on the salts’ effect assessment on the change in moisture content and thermal conductivity of building materials due to the salt solutions and crystals’ presence in the pore space. To study the saline building materials’ thermal conductivity, the mathematical modeling methods using the theory of flow and bringing the materials’ structure to a unit cell are used. It is shown that the change in thermal conductivity occurs due to the crystalline salt precipitation from the solutions in the material’s pores, to the changes in their initial chemical properties, to the changes in the properties of the vapor-air mixture above the salt solutions due to diffusion. The results obtained make it possible to establish the hygroscopic salts’ influence significance in solid and liquid phases on the building materials’ thermal conductivity. A scheme for determining the thermal conductivity of building materials is proposed, taking into account salt effects, including the determination of: the components’ volume concentrations; sequentially the thermal conductivity of the material’s shell; salt crystals, a solid phase consisting of the material’s shell and crystalline salt, a binary and multicomponent saline solution, the pore space and the pore substance inside. The general formula for determining the thermal conductivity of a saline building material is given.
