Published: August 2021

The purpose of this study is to investigate the assets management in the Papua Campus of Institut Pemerintahan Dalam Negeri (IPDN). The research also wants to reveal how the influence of Legal Audit, Human Resources and Leadership Commitments on Optimizing Asset Management. We surveyed on this Campus by selecting a sample of 30 respondents. We empirically tested our hypothesis using Multiple Regression Analysis. The results show that the assets management on this Campus is proper and running under the appropriate statutes. Still, there are needs for more advance and thought in the assets administration, utilization and supervision. Legal audit proved to have a positive but not significant effect on asset management. It means that the audit does not guarantee asset optimization. Human resources and leadership commitments have a positive and significant impact on asset management, reflects that if human resources and leadership commitments are getting more robust, asset management will also be more trustworthy.

The purpose of the study was to explore the correlation between 11С-methionine (Met) uptake measured by combined positron emission and computed tomography (PET/CT) in newly diagnosed cerebral gliomas and tumor proliferative activity as measured by Ki-67 labeling index (Ki-67 LI).The results of PET/CT with 11С-methionine (PET-Met) of 236 adult patients with pretreated glial brain tumors were included in retrospective analysis. The final diagnosis of glioma according to WHO classification of CNS tumors (2007) was based on both histology and immunohistochemistry using Ki-67 antibodies. On PET-Met tumor-to normal brain uptake ratio (TBR) was calculated by dividing maximum Met uptake in the tumor (hot spot 10 mm in diameter) to activity concentration in the contralateral cortex. The Spearmen rank correlation test was used to analyze the relationships between TBR and Ki-67 LI.PET-Met analysis showed that TBR increases with an increase in the aggressiveness of the glial tumor. The differences of TBR values between gliomas grade II vs III and grade III vs IV were significant (p < 0,001). Among grades II-III gliomas Met uptake was significantly higher in oligodendroglial and mixed gliomas than in astrocytomas (p < 0,001), but the differences did not depend on Ki-67 LI.Correlation analysis demonstrated significant correlation between Ki-67 LI and TBR values (r = 0,49, p < 0,05, Spearman rank test). With analyzing glioma subgroups TBR values correlated with Ki-67 LI in diffuse astrocytomas (r = 0,52, p < 0,05), oligodendrogliomas (r = 0,40, p < 0,05), oligoastrocytomas (r = 0,47, p < 0,05) and in high-grade gliomas (r = 0,45, p < 0,05) but not in low-grade gliomas. Comparison between TBR value and Ki-67 LI in each glioma showed a lack of coincidence in 22 % of cases (high Met uptake but low Ki-67 LI and vice versa). The main reasons for such discrepancies were tumor molecular biology or incorrect biopsy target.Met uptake in diffuse gliomas correlates with proliferative activity which justifies the use of PET-Met for glioma grading. In case of mismatch between two biomarkers one should rely on the indicator that implies a higher aggressiveness of the glioma.

Background
Loss of organic matter and mineral nutrients to soil erosion in rain-fed agriculture is a serious problem globally, especially in China’s Loess Plateau. As a result, increasing rainwater usage efficiency by tied-ridge-furrow rainwater harvesting with biochar is expected to improve agricultural productivity. Nonetheless, with limited knowledge on tied-ridge-furrow rainwater harvesting with biochar, small-scale farmers face the challenge of adoption, thus, the rationale for this study.

Materials and methods
A field experiment was conducted to determine the influence of open-ridging (OR) and tied-ridging (TR) with bio-degradable film on ridges and biochar in furrows on runoff, sediment losses, soil moisture, fodder yield, and water use efficiency (WUE) on sloped land, using flat planting (FP) without ridges and furrows as control, during alfalfa-growing year (2020).

Results
Runoff in flat planting (30%), open ridging (45%), and tied ridging (52%) were decreased with biochar to the extent where sediment was decreased in flat planting (33%), open ridging (43%), and tied ridging (44%) as well. The mean runoff efficiency was lower in flat planting (31%), open ridging (45%), and tied ridging (50%) in biochar plots compared to no-biochar plots. In biochar and no-biochar plots, soil temperature on ridges of TR was higher than that on OR, which was higher than FP during alfalfa growing season. Soil temperature in furrows during alfalfa growing season in biochar and no-biochar plots were in the order FP > OR > TR. Mean soil water storage for FP, OR, and TR, in biochar plots was higher than in no-biochar plots. This indicates biochar has a beneficial impact on open riding. Total annual net fodder yield (NFY) was significantly (p = 0.00) higher in treatments in the order TR > OR > FP. Tied ridging had a significant effect on actual fodder yield (AFY) in biochar plots, while open ridging significantly affected AFY in no-biochar plots. Annual total mean NFY and AFY increased by 8% and 11% in biochar plots compared to no-biochar plots. In biochar and no-biochar plots, water use efficiency was in the order TR > OR > FP. Conclusively, water use efficiency was significantly higher (p = 0.01) in biochar plots compared to no-biochar plots.

Conclusion
When crop production is threatened by soil erosion and drought, mulched tied-ridge with biochar is beneficial to crop growth in rain-fed agriculture, according to this research. Smallholder farmers should be trained on applying this technique for water-saving to mitigate runoff, soil erosion, sediment losses, and improve food security in semiarid areas.

Published: August 2021

To study the potential relationship between melatonin and beta‐amyloid (Abeta), we established a liquid chromatography–mass spectrometry (LC‐MS) method to quantitatively analyze melatonin, deuterated isotopes (melatonin‐D4), and internal standard 6‐iodo‐2‐(4'‐dimethylamino‐) phenyl‐imidazo(1,2) pyridine (IMPY) under positive (+) mode. The gradient elution was set to 6 min, and the corresponding peak time of melatonin and its isotope melatonin‐D4 was 3.14 min, while the peak time for the internal standard IMPY was 3.24 min. Next, we established and optimized the molecule receptor saturation binding assay based on LC‐MS to determine the melatonin affinity for beta‐amyloid (Abeta). Melatonin showed a high and specific binding for Abeta. The corresponding equilibrium dissociation constant (Kd) of melatonin with Abeta 1‐40 and Abeta 1‐42 was 814.37 ± 36.62 and 628.33 ± 13.57 nmol·L−1; besides, the Kd of melatonin with mixed plaques (1‐40 and 1‐42) was 461.13 ± 45.37 nmol·L−1. The results may suggest the potential mechanism of action of MT on Abeta and provide a theoretical basis for the improvement of MT treatment of Alzheimer's disease.
Social skills moderate the time‐varying association between aggression and peer rejection among children with and without ADHD

Published: August 2021

AbstractAlthough childhood aggression is typically associated with peer rejection, some children concurrently employ coercive and socially skilled behavior and successfully avoid negative peer outcomes. However, research on children's dual use of coercive and social behavior has largely employed cross‐sectional designs with nonclinical populations and, as a result, little is known about the covariation of aggression with social skills, particularly among high‐risk samples. We directly addressed this limitation by testing childhood aggression and social skills as separate time‐varying predictors of prospective change in peer rejection in a sample of children with and without attention‐deficit/hyperactivity disorder (ADHD). Two hundred and two 5–10‐year‐old children (M = 7.9 years, SD = 1.2) with and without ADHD were followed prospectively for 6 years. Key constructs, including children's overt aggression, social skills, and peer rejection, were collected at each of the three waves using multiple methods and informants. Controlling for demographic factors and time‐varying ADHD symptoms, longitudinal change in child‐, parent‐, and teacher‐reported aggression positively predicted prospective change in parent‐ and teacher‐reported peer rejection. Importantly, predictions were moderated by parent‐ and teacher‐reported social skills, such that aggression inversely predicted peer rejection for children with high social skills. These results demonstrate that social skills meaningfully alter trajectories of peer rejection predicted from cross‐time variation in aggression. We discuss the theoretical and empirical implications of these findings within a developmental psychopathology framework, including recommendations for directions for future research.

AbstractThe sub‐picosecond response of amorphous germanium telluride thin film to a femtosecond laser excitation is investigated using frequency‐domain interferometry and ab initio molecular dynamics. The time‐resolved measurement of the surface dynamics reveals a shrinkage of the film with a dielectric properties’ response faster than 300 fs. The systematic ab initio molecular dynamics simulations in non‐equilibrium conditions allow the atomic configurations to be retrieved for ionic temperature from 300 to 1100 K and width of the electron distribution from 0.001 to 1.0 eV. Local order of the structures is characterized by in‐depth analysis of the angle distribution, phonon modes, and pair distribution function, which evidence a transition toward a new amorphous electronic excited state close in bonding/structure to the liquid state. The results shed a new light on the optically highly excited states in chalcogenide materials involved in both important processes: phase‐change materials in memory devices and ovonic threshold switching phenomenon induced by a static field.

AbstractThe hexagonal epithelial cells covered with mucus are believed to be responsible for the superior adhesion ability of tree frogs under dry and wet conditions. In spite of good progress made in the past years, many questions about the mechanism of wet adhesion remain to be addressed. Here, a tree frog‐inspired wet adhesive, termed structured hydrogel adhesive, with poly(acrylamide)/poly(vinyl alcohol) hydrogel to mimic the hexagonal epithelial cells and glycerol–water mixture to mimic the mucus is reported. The combined analysis of adhesion force and work of adhesion reveals the major contribution of direct solid–solid contact in wet adhesion. The contributions of capillarity and viscosity of liquid are qualitatively decoupled by regulating the fluid components and the temperature. The study offers an excellent model system and a great opportunity to gain deep insight into wet adhesion of animals, like tree frogs, which may pave the way for the design of adhesives for wet environments.

Published: August 2021

AbstractOver the years, organic optoelectronics have evolved into a mature technology with a wide range of applications. Their building blocks, namely organic semiconductors, are distinctly different from their inorganic counterparts due to orientational degrees of freedom that offer unique possibilities for tailoring their properties in thin‐film structures. In this article, the many facets that molecular orientation has for fundamental aspects, like film growth as well as optical and electrical behavior, are reviewed and the implications of molecular orientation for device application are discussed.

Published: August 2021

AbstractAs additive manufacturing (AM) expands as a processing technology for structurally customizable materials, there is increasing interest in printing with high particle contents. For suspensions with particle contents of over 50 vol%, there are significant formulation and processing challenges due to increased interparticle friction and suspension complexity. We focus on suspensions with bimodal particle distributions and two common binder systems, a high molecular weight polymer in a solvent that solidifies via solvent evaporation and a monomer mixture that cures via ultraviolet irradiation. We examine the interplay between formulation and processing and show that the formulation effects are particularly important at optimal printing parameters, but that they are overcome by processing‐related defects at sub‐optimal parameters. By understanding the processing and formulation effects specific to direct ink write AM of high solids suspensions, new customized inks can be designed for a wide range of applications, including construction, energetics, and ceramics.

AbstractGuided by a second‐sphere interaction strategy, we fabricated a Tb(III)‐based metal—organic framework (MMCF‐4) for turn‐on sensing of methyl amine with ultra‐low detection limit and high turn‐on efficiency. MMCF‐4 features lanthanide nodes shielded in a nonacoordinate geometry along with secondary coordination spheres that are densely populated with H‐bond interacting sites. Nonradiative routes were inhibited by binding‐induced rigidification of the ligand on the second coordination sphere, resulting in luminescence amplification. Such remote interacting mechanism involved in the turn‐on sensing event was confirmed by single‐crystal X‐ray diffraction and molecular dynamic simulation studies. The design of both primary and secondary coordination spheres of Tb(III) enabled the first turn‐on sensing of organic amines in aqueous conditions. Our work suggests a promising strategy for high‐performance turn‐on sensing for Ln‐MOFs and luminous materials driven by other metal chromophores.

Published: August 2021

AbstractNO is a harmful pollutant to the environment. The traditional removal of NO is hindered by the harsh operating conditions and sacrifice of value‐added chemicals. Efficient electrocatalytic oxidation of NO was achieved over plasma‐treated commercial carbon cloth, serving as a promising anode substitution reaction to couple with the hydrogen evolution reaction without consumption of hydrogen‐containing resources. The introduction of carboxyl groups onto the carbon cloth boosted the electrocatalytic activity via the enhancement of NO chemisorption. Only potentials of 1.39 V and 1.07 V were applied to reach the current density of 10 mA cm−2in neutral and acidic conditions, respectively, which is superior to the state‐of‐the‐art electrocatalysts for oxygen evolution. Energy and environmental concerns on fossil‐fuel‐derived hydrogen production, ammonia manufacture and nitrate synthesis, are greatly alleviated. This work provides an original strategy to realize the resource utilization of NO, the sustainable nitrate synthesis and hydrogen production in a green and economical way.

AbstractDesigning definite metal‐support interfacial bond is an effective strategy for optimizing the intrinsic activity of noble metals, but rather challenging. Herein, a series of quantum‐sized metal nanoparticles (NPs) anchored on nickel metal–organic framework nanohybrids (M@Ni‐MOF, M=Ru, Ir, Pd) are rationally developed through a spontaneous redox strategy. The metal‐oxygen bonds between the NPs and Ni‐MOF guarantee structural stability and sufficient exposure of the surface active sites. More importantly, such precise interfacial feature can effectively modulate the electronic structure of hybrids through the charge transfer of the formed Ni‐O‐M bridge and then improves the reaction kinetics. As a result, the representative Ru@Ni‐MOF exhibits excellent hydrogen evolution reaction (HER) activity at all pH values, even superior to commercial Pt/C and recent noble‐metal catalysts. Theoretical calculations deepen the mechanism understanding of the superior HER performance of Ru@Ni‐MOF through the optimized adsorption free energies of water and hydrogen due to the interfacial‐bond‐induced electron redistribution.

AbstractWe report a Ni‐catalyzed regioselective arylbenzylation of alkenylarenes with benzyl halides and arylzinc reagents. The reaction furnishes differently substituted 1,1,3‐triarylpropyl structures that are reminiscent of the cores of oligoresveratrol natural products. The reaction is also compatible for the coupling of internal alkenes, secondary benzyl halides and variously substituted arylzinc reagents. Kinetic studies reveal that the reaction proceeds with a rate‐limiting single‐electron‐transfer process and is autocatalyzed by in‐situ‐generated ZnX2. The reaction rate is amplified by a factor of three through autocatalysis upon addition of ZnX2.

AbstractNovel palladium‐doped nanoporous carbon composite material obtained via thermolysis of amorphous zeolitic imidazolate framework (aZIF) was synthesized and used as an efficient catalyst on Suzuki–Miyaura cross‐coupling reactions of aryl bromides. With this developed catalytic system, the Suzuki–Miyaura cross‐coupling reaction was accomplished in aqueous solutions, and biaryls were obtained in good to excellent yields in a short reaction time. The APC‐750@Pd catalyst was characterized by Fourier Transform Infrared spectroscopy (FTIR), X‐ray Diffraction (XRD), Scanning Electron Eicroscopy (SEM), X‐ray Photoelectron Spectroscopy (XPS), Transmission Electron Microscopy (TEM), Thermal Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA), Inductively Coupled Plasma Mass Spectrometry (ICP‐MS) and Brunauer–Emmett–Teller (BET) analysis tecniques. N‐doped porous carbon material (NPC‐1000) was synthesized by thermolysis from aZIF. Activated porous carbon material (APC‐750) was fabricated via fused at 750°C with KOH from NPC‐1000. The APC‐750@Pd was obtained as a result of the interaction of APC‐750 and PdCl2in deionized water. The cross‐coupling reaction of different aryl bromides with phenylboronic acid was investigated to show the potential of the APC‐750@Pd in the Suzuki–Miyaura cross‐coupling reactions. The APC‐750@Pd catalyst could be recycled at least five times with a 15% loss of catalytic efficiency in this catalytic system.
