Authors: Faisal A , Riza F V , Hadibroto B 
Published: November 2019

Abstract
The directivity pulse motion in near-field earthquake affects the responses of structures. The response includes the roof drifts and interstory drifts, which is so-called the ductility demand. Although many studies have done in this topic, the effect of various post-yield stiffness ratio and ductility capacity ratio to the global ductility demands of reinforced concrete (RC) frames under near-field ground motion is not specifically investigated yet. The trend of global ductility demands of RC frames under near-field earthquake is the objective of this study. The frames are modeled with various fundamental period, behavior factor, plastic rotation capacity, post-yield stiffness ratio, and ductility capacity ratio. The study reveals that the effect of ductility capacity ratio on the global ductility demands is apparent as as the plastic rotation capacity changes. The global ductility demand is also found influenced by global post-yield stiffness ratio and behavior factor.

Published: November 2019

Abstract
Responding to the effects of the earthquake and tsunami in 2004, Badan Rehabilitasi dan Rekonstruksi Nanggroe Aceh Darussalam-Nias (BRR NAD-Nias) was assigned as the coordinating and executing agency for improving the region in Aceh province and Nias islands in Indonesia. The allocation for the projects directly implemented by the BRR was approximately USD 2.6 billion. Based on local regulation, these assets must be turned over to the Aceh government. Although most assets were already occupied, neither an appropriate handover nor external project evaluation was conducted. This preliminary study surveyed opinions from building users regarding building quality, the need for building evaluation, and the general opinion for occupying assets with no appropriate handover process in a post-disaster context. The samples included a school, health center, and a sub-district level government office in Banda Aceh city. This study used descriptive methods and a quantitative approach. Results showed the majority of respondents doubted the quality and condition of the assets and agreed with the importance of conducting asset evaluation. However, they are uncertain whether occupying assets before an appropriate handover was appropriate because the post-disaster situation required assets to be functional as soon as possible.

Authors: Lubis S , Cholish  
Published: November 2019

Abstract
The alternator is a critical component. The car alternator issued AC electric power by utilizing wind power rotation is then converted into DC electrical power supplied to the accumulator before. Therefore, it is not required of operators to operate the working of the alternator. The voltage generated cells in a standard battery is 2V / cell. However, the working voltage is higher. As is known, in order to drain current through a battery, alternator voltage should be higher than the voltage of the batteries themselves. On the other hand must be maintained so that the voltage is not too high to prevent boiling of (gas) from the batteries. As the voltage regulator safe at 200 ° C should be maintained to 2.35 V / cell until 2.4 V / cell. For 12V battery it means that the working voltage of 14.1 V-14.

Published: November 2019

Abstract
The objective of present research work is to investigate the surface morphology and surface microhardness of unidirectional E-glass fiber epoxy composites filled with varying amount of ZnO nanofiller content such as 1, 2, 3, 4 and 5 wt% respectively. ZnO nanofiller was added to the epoxy resin matrix in varying amount (wt%) using mechanical stirrer and followed by ultrasonication process. The laminate composites were fabricated using a compression molding press technique. Further, laminate composites were subjected to individual characterization and testing according to ASTM standards. The crystalline nature of ZnO nanofiller was studied using x-ray diffraction analysis (XRD) and surface morphology of ZnO nanofiller on the resin surface was examined by using a scanning electron microscope (SEM). The experimental test results revealed that addition of nanofiller content by 1, 2 and 3 wt% resulted in a gradual reduction of void fraction and thereafter increase in void fraction was observed with 4 and 5 wt% of ZnO loading. The surface microhardness results indicated a linear increment with increase in ZnO nanofiller loading from 1 to 5 wt%. Further, surface topography was studied with the help of atomic force microscopy (AFM), to obtain the surface roughness values. The surface roughness values increased with increase in ZnO wt% within the epoxy resin matrix. The results of the surface analysis of the fabricated composites indicate that at higher loading of ZnO nanofiller, there is formation of clusters and agglomerates of the nanofiller which reduces the nano-scale effects of the filler and nanofillers tend to behave as micro-fillers.
Fast speciations and slow genes: uncovering the root of living canids
Authors: Lamarca Alessandra P , Schrago Carlos G 
Published: November 2019

AbstractDespite ongoing efforts relying on computationally intensive tree-building methods and large datasets, the deeper phylogenetic relationships between living canid genera remain controversial. We demonstrate that this issue arises fundamentally from the uncertainty of root placement as a consequence of the short length of the branch connecting the major canid clades, which probably resulted from a fast radiation during the early diversification of extant Canidae. Using both nuclear and mitochondrial genes, we investigate the position of the canid root and its consistency by using three rooting methods. We find that mitochondrial genomes consistently retrieve a root node separating the tribe Canini from the remaining canids, whereas nuclear data mostly recover a root that places the Urocyon foxes as the sister lineage of living canids. We demonstrate that, to resolve the canid root, the nuclear segments sequenced so far are significantly less informative than mitochondrial genomes. We also propose that short intervals between speciations obscure the place of the true root, because methods are susceptible to stochastic error in the presence of short internal branches near the root.

Abstract
In vitro reconstitution of germ-cell development from pluripotent stem cells (PSCs) has created key opportunities to explore the fundamental mechanisms underlying germ-cell development, particularly in mice and humans. Importantly, such investigations have clarified critical species differences in the mechanisms regulating mouse and human germ-cell development, highlighting the necessity of establishing an in vitro germ-cell development system in other mammals, such as non-human primates. Here, we show that multiple lines of embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) in cynomolgus monkeys (Macaca fascicularis; cy) can be maintained stably in an undifferentiated state under a defined condition with an inhibitor for WNT signaling, and such PSCs are induced efficiently into primordial germ cell-like cells (PGCLCs) bearing a transcriptome similar to early cyPGCs. Interestingly, the induction kinetics of cyPGCLCs from cyPSCs is faster than that of human (h) PGCLCs from hPSCs, and while the transcriptome dynamics during cyPGCLC induction is relatively similar to that during hPGCLC induction, it is substantially divergent from that during mouse (m) PGCLC induction. Our findings delineate common as well as species-specific traits for PGC specification, creating a foundation for parallel investigations into the mechanism for germ-cell development in mice, monkeys, and humans.
Gonadotrope-specific deletion of the BMP type 2 receptor does not affect reproductive physiology in mice†‡
Authors: Ongaro Luisina , Zhou Xiang , Cui Yiming , Boehm Ulrich , Bernard Daniel J 
Published: November 2019

Abstract
Activins selectively stimulate follicle-stimulating hormone (FSH) secretion by pituitary gonadotrope cells. More recently, other members of the TGFbeta superfamily, the bone morphogenetic proteins (BMPs), were reported to regulate FSH synthesis. Activins and BMPs independently and synergistically stimulate transcription of the FSHbeta subunit (Fshb) gene in immortalized gonadotrope-like cells. Both ligands can signal via the activin receptor type IIA (ACVR2A) to regulate FSH synthesis in vitro. In vivo, global Acvr2a knockout mice exhibit a 60% reduction in circulating FSH relative to wild-type animals, suggesting that activins, BMPs, or related ligands might signal through additional type II receptors to regulate FSH in vivo. Although the leading candidates are ACVR2B and the BMP type II receptor (BMPR2), only the latter mediates activin or BMP2 induction of Fshb transcription in vitro. Here, we generated mice carrying a loss of function mutation in Bmpr2 specifically in gonadotropes. Puberty onset, estrous cyclicity, and reproductive organ weights were similar between control and conditional knockout females. Serum FSH and luteinizing hormone (LH) and pituitary expression of Fshb and the LHbeta subunit (Lhb) were similarly unaffected by the gene deletion in both sexes. These results suggest that BMPR2 might not play a necessary role in FSH synthesis or secretion in vivo or that another type II receptor, such as ACVR2A, can fully compensate for its absence. These data also further contribute to the emerging concept that BMPs may not be physiological regulators of FSH in vivo.
Transcriptome analysis during photostimulated recrudescence reveals distinct patterns of gene regulation in Siberian hamster ovaries†
Authors: Leon Kathleen , Hennebold Jon D , Fei Suzanne S , Young Kelly A 
Published: November 2019

AbstractIn Siberian hamsters, exposure to short days (SDs, 8 h light:16 h dark) reduces reproductive function centrally by decreasing gonadotropin secretion, whereas subsequent transfer of photoinhibited hamsters to stimulatory long days (LDs, 16 L:8 D) promotes follicle stimulating hormone (FSH) release inducing ovarian recrudescence. Although differences between SD and LD ovaries have been investigated, a systematic investigation of the ovarian transcriptome across photoperiod groups to identify potentially novel factors that contribute to photostimulated restoration of ovarian function had not been conducted. Hamsters were assigned to one of four photoperiod groups: LD to maintain ovarian cyclicity, SD to induce ovarian regression, or post transfer (PT), where females housed in SD for 14-weeks were transferred to LD for 2-days or 1-week to reflect photostimulated ovaries prior to (PTd2) and following (PTw1) the return of systemic FSH. Ovarian RNA was extracted to create RNA-sequencing libraries and short-read sequencing Illumina assays that mapped and quantified the ovarian transcriptomes (n = 4/group). Ovarian and uterine masses, plasma FSH, and numbers of antral follicles and corpora lutea decreased in SD as compared to LD ovaries (P &lt; 0.05). When reads were aligned to the mouse genome, 18 548 genes were sufficiently quantified. Most of the differentially expressed genes noted between functional LD ovaries and regressed SD ovaries; however, five main expression patterns were identified across photoperiod groups. These results, generally corroborated by select protein immunostaining, provide a map of photoregulated ovary function and identify novel genes that may contribute to the photostimulated resumption of ovarian activity.
