Authors: Yuskiv L. L. , Vlizlo V. 
Published: November 2018

The article contains data on the content of active metabolite of vitamin D3 – 25OHD3, calcium, phosphorus, magnesium and activity of alkaline phosphatase in the blood of cows and their calves in the early postnatal period. The experiment was conducted on cows-analogues of the Ukrainian Black-and-White dairy breed during the dry period and after calving and on calves received from them. The experiment was performed during the winter period of the stall at the Lviv region farm. The blood for tests was collected from the jugular vein before morning feeding at 3–5 days before calving and in the 5th–7th and 55th–60th days after calving. The blood from the calves was collected in the following dates: on the first day and at 5th–7th days old and at 55–60th days old. It was established that, the content of 25-hydroxycolecalciferol in blood calves on the first day after birth was 18.90 ± 2.08 nmol/l. In subsequent periods of study, its level decreased, in particular, at 5th−7th days old it was 1.52 times lower (P < 0.05), and in the at 55–60th days old – 2.07 times (P < 0.01) than on the first day old age during the winter period of the stall. Changes in the content of 25OHD3, total calcium and its fractions, inorganic phosphorus, magnesium and activity of alkaline phosphatase and its isoenzymes in the blood of cows in the prenatal and lactation periods have been determined. In particular, the content of 25OHD3 was 18.7 ± 2.27 nmol/l at 3–5 days before calving in the blood of cows, on the 5–7th day after calving continued to decrease and amounted to 15.8 ± 0.83 nmol/l, and on the 55–60th day of the postpartum period it increased to 20.5 ± 2.08 nmol/l.

<p>Maternal Mortality Rate of Padang City in 2016 reached 20 deaths. 10 cases of maternal deaths due to 3 cases of bleeding, 2 infections and 5 cases of Hypertension in Pregnancy. The purpose of this research is to know what factors influence the cause of maternal death in Padang city in 2017.The research is Mixed Metodes with sequential explanatory design conducted on June 16 until July 15, 2017 in the working area of Puskesmas in Padang City, DKK Padang and KUA Kuranji. Data collection by interview using questionnaires and interview guides. Respondents were case mothers totaling 7 people and control of 4 puskesmas that had death and 1 puskesmas with no maternal deaths amounting to 42 respondents. The informants were 7 heads of puskesmas, program holders of KIA Puskesmas and DKK Padang, and head of KUA. Processing and quantitative analysis with univariate, bivariate and multivariate while qualitative data reduction, categorization and sintesisasi poured form of matrix and described form of narration.The results of research on education level, anemia status, history of complication, age, parity, pregnancy distance, standard 7T midwife care, KB use, decision making and mother referral have relationship to maternal death. Nutritional status, ANC visits and handling at the referral facility did not have a significant relationship to maternal deaths. The most influential variable on the incidence of maternal death is the standard 7T midwife care.Input, the determinants of education has affect maternal mortality. The process, the determinant between all health of both mother and child and ministry of religion programs has not run optimally. Output, close determinants of complications and all risk factors that exist occur because the quality of services provided is not optimal. It is expected that Puskesmas in Padang city run all health of both mother and child programs maximally. Cross-sectoral cooperation with ministry of religion, mother affection movement to be more implemented maximally and continuum of care can be done.</p>
The Magnetic Nature of the Cataclysmic Variable Period Gap

Published: November 2018

Abstract
One of the most important problems in the context of cataclysmic variables (CVs) is the lack of observations of systems with periods between 2 and 3.12 hr, known as the period gap. The orbital evolution of CVs with periods shorter than those in the gap is dominated by gravitational radiation, while for periods exceeding those of the gap it is dominated by magnetic braking of the secondary star. Spruit & Ritter showed that as periods approach 3 hr and secondary stars become fully convective a sharp decline in magnetic dynamo and braking efficiency would result in such a gap. Recent X-ray observations finding coronal magnetic energy dissipation is similar in fully convective and partly radiative M dwarfs cast this theory into doubt. In this work, we use Zeeman–Doppler imaging observations culled from the literature to show that the complexity of the surface magnetic fields of rapidly rotating M dwarfs increases with decreasing rotation period. Garraffo et al. have shown that the efficiency of angular momentum loss of cool stars declines strongly with increasing complexity of their surface magnetic field. We explore the idea of Taam & Spruit that magnetic complexity might then explain the period gap. By generating synthetic CV populations using a schematic CV evolutionary approach, we show that the CV period gap can naturally arise as a consequence of a rise in secondary star magnetic complexity near the long-period edge of the gap that renders a sharp decline in their angular-momentum-loss rate.

Abstract
We report X-ray, optical, and near-infrared monitoring of the new X-ray transient MAXI J1820+070 discovered with MAXI on 2018 March 11. Its X-ray intensity reached ∼2 crab at 2–20 keV at the end of March, and then gradually decreased until the middle of June. In this period, the X-ray spectrum was described by Comptonization of the disk emission, with a photon index of ∼1.5 and an electron temperature of ∼50 keV, which is consistent with a black hole X-ray binary in the low/hard state. The electron temperature was slightly decreased, and the photon index increased, with increasing flux. The source showed significant X-ray flux variation on a timescale of seconds. This short-term variation was found to be associated with changes in the spectral shape, and the photon index became slightly harder at higher fluxes. This suggests that the variation was produced by a change in the properties of the hot electron cloud responsible for the strong Comptonization. Modeling a multi-wavelength spectral energy distribution around the X-ray flux peak at the end of March, covering the near-infrared to X-ray bands, we found that the optical and near-infrared fluxes were likely contributed substantially by the jet emission. Before this outburst, the source was never detected in the X-ray band with MAXI (with a 3σ upper limit of ∼0.2 mcrab at 4–10 keV, obtained from seven years of data from 2009 to 2016), whereas weak optical and infrared activity was found at flux levels ∼3 orders of magnitude lower than the peak fluxes in the outburst.

Effect of Therapy on Choroidal Thickness in Patients With Obstructive Sleep Apnea Syndrome
Authors: Uslu Hasim , Kanra Ayşe Yağmur , Cetintas Gulgun , Tatar Mehmet Gurkan 
Published: November 2018

BACKGROUND AND OBJECTIVE:
To evaluate effect of continuous positive airway pressure (CPAP) therapy on choroidal thickness in patients with obstructive sleep apnea syndrome (OSAS).

PATIENTS AND METHODS:
Thirty distinct eyes of 30 patients with OSAS were evaluated right before and 12 months after CPAP treatment in this prospective observational study. Choroidal thickness was measured at the fovea and with periodic intervals of 500 µm from the foveal center in both temporal and nasal directions using spectral-domain optical coherence tomography in enhanced depth imaging mode.

RESULTS:

The patients' mean age was 45.33 years ± 7.74 years, and there were eight females and 22 males. After CPAP therapy, the choroidal thicknesses were increased significantly at the subfoveal, 500 µm nasal to the fovea, 500 µm temporal to the fovea, and 1,000 µm temporal to fovea points (
P
< .05). However, none of retinal macular parameters were significantly different in statistical terms between the two measurements (
P
> .05).

CONCLUSIONS:
CPAP therapy had a significant influence on choroidal thickness in patients with OSAS, providing an increase in choroidal thicknesses after 12 months. The determination of an increase in choroidal thickness may be useful to reveal the effects of CPAP therapy and also may be one of the mechanisms to improve choroidal function.

Correlation of “Panoramic” Optical Coherence Tomography Angiography With Indocyanine Green Angiography Characteristics of Serpiginous-Like Choroiditis
Authors: Nagpal Manish , Mehrotra Navneet , Juneja Rakesh , Vishnoi Avijit , Jain Ashish 
Published: November 2018

BACKGROUND AND OBJECTIVES:
To analyze the panorama optical coherence tomography angiography (P-OCTA) characteristics of serpiginous-like choroiditis (SLC) and to correlate these findings with indocyanine green angiography (ICGA).

PATIENTS AND METHODS:
Prospective, observational study of 32 eyes of 24 patients. Twenty-seven eyes of 16 patients who met inclusion criteria were included in the final study. Multimodal imaging was performed using P-OCTA, OCT, fundus autofluorescence, fluorescein angiography, and ICGA. Morphologic features at the site of lesions were analyzed using P-OCTA and correlated with ICGA.

RESULTS:
P-OCTA in active phase revealed areas of large flow void, which correlated with hypofluorescent areas on ICGA. Healing phase revealed appearance of vascular network due unmasking of choriocapillaris that corresponded to reduced hypofluorescence on ICGA.

CONCLUSION:
P-OCTA as a noninvasive tool provides widefield and high-resolution images that can be used as an complementary tool to ICGA for diagnosis of SLC cases.

Measuring Social Communication in the Community: Novel Tools for Advancing Family Participation
Authors: Irvin Dwight W. , Bard Anna , Wallisch Anna , Little Lauren M. 
Published: November 2018

Abstract
Natural contexts and family involvement are key features of effective intervention approaches. However, the measurement of community participation and parent engagement with children remains complex. Therefore, we examined the feasibility of combining use of the Language ENvironment Analysis (LENA®) system and a global positioning system (GPS; i.e., Qstarz® BT-Q1000XT). The LENA is a small speech recognition device that captures and quantifies full-day recordings of the natural language environment. The Qstarz BT-Q1000XT is a wearable GPS data logger that allows identification of the locations a person visits. The marrying of these measures allows for an accurate representation of community settings that afford children greater social communication opportunities. Our results show that the combination of measures provides meaningful social communication location data. Also, the participating caregiver reported that the collection of measures was feasible across community settings.

Published: November 2018

The paper examines the relationship between weather and stock market returns in the Argentina’s stock market using daily data from 2001 to 2014 and regression models. The data consists of stock market returns, temperature, humidity and wind. The empirical findings show that all weather variables (temperature, humidity and wind) have significant relationship with stock market returns in some of the trading days in the week. We also find evidence of the existence of day-of-week effect in the stock market. On average, the highest return falls on Friday and lowest return falls on Monday. Temperature is considered very significant in influencing the stock market returns in Argentina. Our findings suggest that the stock market returns are higher when the temperature is higher. This phenomenon is related to the seasonal affective disorder (SAD). We can conclude that stock market of Argentina is not informational efficient. The results have major implications for traders, individual investors, fund managers and financial institutions to make investment planning in the Argentina’s stock market.

Objective: To report the experience developed in a Third Level Referral Center in performing a multifaceted intervention strategy to reduce Caesarian Sections (CS) rate. A comparison of our results with the performance of the best Italian hospitals for number of deliveries and CS has been performed.Methods: A monitoring system was set up, based on a prospective collection of all deliveries from 2013 to 2017, according to Robson’s classification. Data have also been collected retrospectively at a regional and national level to compare our results to other institutions. The multi-approach intervention consisted of evidence based tools: process management, training, multiprofessionalism, development of planning and control systems, continuous monitoring, audit and feedback.Results: The percentage of primary CS decreased from 26.71% in 2013 to 15.03% in 2017 (RR adjusted considering the regional average: 0.87 in 2013; 0.57 in 2017, p < .001). A raise of 19.76% in the annual volume of deliveries was registered. Such results have also been confirmed after comparing to the best performing Italian centers. From 2013 to 2016 the percentage of primary CS decreased from 27.02% to 18.04% (RR adjusted considering the regional average: 1.04 in 2013, p > .05; 0.74 in 2016, p < .001), while there was an increase in the annual volume of deliveries from 3,311 to 4,219.Conclusions: Our study confirms that multifaceted interventions can strengthen a continuous quality and safety improvement approach. This is of crucial relevance in the obstetric field and in the Italian country, where overall performance in CS needs to be improved.

Authors: Hodgson Alex , Cochran Jack 
Published: November 2018

Abstract
Background: Traditional detectors such as flame ionization detection and MS have issues with coeluting isomers like terpenes; however, unique vacuum UV (VUV) absorbance spectra can be used to deliberately compress chromatography. Objective: Deconvolution capabilities under various run conditions of GC-MS and GC-VUV arecompared. Methods: A standard terpenes mix and tea tree essential oil were run on both GC-MS (63 and 14 min run times) and GC-VUV (22, 11, and 7 min run times). Results: The three GC-VUV methods showed good precision for10 terpenes, as well as with the 63 min GC-MS method. The 14 min GC-MS method struggled precisely quantifying some terpenes. Highlights: GC-VUV allows for faster run times while providing the same level of quantitative accuracy.
Transition, not revolution

Published: November 2018

Watch the VIDEO.This presentation is aiming to discuss the effects of conversion of a journal to OA and suggests that this is likely to cause a loss of authorship of the journal. Further, we conclude that transitioning to OA via hybrid models is a more sustainable approach than flipping all journals to OA at once.As an example we use RSC Advances – a high quality journal in multidisciplinary chemistry published by RSC.Since launch in 2012, RSC Advances has achieved rapid growth and worldwide acceptance. In 2016 we converted RSC Advances to OA to:• give researchers free access to a broad scope of quality work• make the research we publish more visible• positively influence the future of OA publishing• demonstrate that OA publishing can be both affordable, and sustainableAn anticipated result of flipping to open access is the loss of authorship and submissions to competing journals. In fact, in 2017 just over 6600 articles were published in RSC Advances – less than a half of the publishing output in 2016. The loss of authorship and a risk of authors choosing to publish in a competing journal is the reason why RSC cannot go full OA (all journals) yet.This does not mean that RSC suspended the support of OA. We continue introducing new OA journals like Nanoscale Advances, and new OA transition models like Read & Publish, which allows authors to access all content behind paywall and publish OA at no extra cost.
Vanadium Doping Enhanced Electrochemical Performance of Molybdenum Oxide in Lithium‐Ion Batteries

Published: November 2018

AbstractMolybdenum trioxide (MoO3) suffers from poor conductivity, a low rate capability, and unsatisfactory cycling stability in lithium‐ion batteries. The aliovalent ion doping may present an effective way to improve the electrochemical performances of MoO3. Here, it is shown, by first‐principle calculations, that doping MoO3 with V by 12.5% can modulate significantly electronic structure and provide a small diffusion barrier for enhancing the electrochemical performance of MoO3. The ultralong Mo0.88V0.12O2.94 nanostructures, which retain the h‐MoO3 structure and present an exceptionally high conductivity and fast ionic diffusion due to the substitution of V, facilitating lithiation/delithiation behavior, and induce a fine nanosized structure with a reduced volume change are prepared. As a result, the stress and strain are alleviated during the Li‐ion intercalation/deintercalation processes, improving the cycling stability and rate capability. Such a large improvement in the electrochemical properties can be ascribed to the stabilizing effect of V, the small migration energy barrier, and short diffusion path, which arise from the introduction of V into MoO3. The unique engineering strategy and facile synthesis route open up a new avenue in modifying and developing other species of electrode materials.

Published: November 2018

AbstractDual‐ion batteries (DIBs) have attracted much attention due to their advantages of low cost and especially environmental friendliness. However, the capacities of most DIBs are still unsatisfied (≈100 mAh g−1) ascribed to the limited capacity of anions intercalation for conventional graphite cathode. In this study, 3D porous microcrystalline carbon (3D‐PMC) was designed and synthesized via a self‐templated growth approach, and when used as cathode for a DIB, it allows both intercalation and adsorption of anions. The microcrystalline carbon is beneficial to obtain capacity originated from anions intercalation, and the 3D porous structure with a certain surface area contributes to anions adsorption capacity. With the synergistic effect, this 3D‐PMC is utilized as cathode and tin as anode for a sodium‐based DIB, which has a high capacity of 168.0 mAh g−1 at 0.3 A g−1, among the best values of reported DIBs so far. This cell also exhibits long‐term cycling stability with a capacity retention of ≈70% after 2000 cycles at a high current rate of 1 A g−1. It is believed that this work will provide a strategy to develop high‐performance cathode materials for DIBs.

Published: November 2018

AbstractAs one of the most widely discussed fields, the assembly of nanomaterials has always been extensively studied. However, its inverse process, namely disassembly, is still limited in the ambit of biomolecules. Specifically, in the emerging 2D research field, disassembly still remains unexplored. Inspired by the disassembly of DNA molecules via breaking intermolecular hydrogen bonds, the disassembly of 2D vertical heterostructures (2DVHs) is first achieved through the weakening of the interlayer van der Waals interactions. As a demonstration, ReS2/WS2 VHs is successfully disassembled into individual building blocks. Density functional theory calculations are performed to study the disassembly of the 2DVHs, which simulate that 2DVHs are first activated by the disassembly promoters and then disassembled with weakened interlayer van der Waals interactions. Such a disassembly process demonstrates that it has great potential to be expanded as a general strategy to achieve the disassembly of other 2D superstructures.
