A Free Phosphaborene Stable at Room Temperature
Authors: Li Jiancheng , Lu Zhihao , Liu Liu Leo
Published: December 2022

Free phosphaborenes (R−P=B−R) are PB analogs of alkynes and their isolation is a long-sought-after goal. Herein, we demonstrate that the combination of a π-donating and a π-accepting substituent with bulky flanking arene rings enables the isolation of a crystal-line free phosphaborene 5 at room temperature. This electron push-pull cooperation, combined with the kinetic protection, hinders its inherent tendency to oligomerize. This species features a PB double bond consisting of a conventional σ bond and a delocalized π bond. The lone pair of electrons at P slightly contributes to the PB bonding. Preliminary reactivity studies show that 5 undergoes facile (cyclo)addition reactions with p-methyl benzaldehyde, p-fluoroacetophenone and carbon disulfide, the last of which results in facile PB double bond cleavage. Our strategy has a significant impact on the future synthesis of ambiphilic heterodiatomic multiply bonded main group species.

Lysyl hydroxylase 2 (LH2), an Fe(II) and α-ketoglutarate (αKG, also called 2-oxoglutarate, or 2OG)-dependent oxygenase, is an endoplasmic reticulum-resident enzyme that hydroxylates telopeptidyl lysine residues on fibrillar collagen molecules. It leads to the formation of hydroxylysine aldehyde-derived collagen cross-links (HLCCs), which are more stable than lysine aldehyde-derived collagen cross-links (LCCs) generated devoid of LH2. It has been reported that LH2 enhances lung cancer metastatic and invasive proclivity and modulates the types of collagen cross-links (HLCC-to-LCC) in the tumor stroma. Herein, we prepared a series of 1,3-diketone analogs 1–18 and identified 12 and 13 that inhibit the LH2-driven hydroxylation of a collagen peptide substrate with IC50 approximately 300 nM and 500 nM, respectively. 12 and 13 demonstrate a 9-fold selectivity for LH2 over LH1 and LH3. Quantum Mechanics/Molecular Mechanics (QM/MM) modeling indicates that in addition to the relatively stronger interactions between compounds 12 and 13 with the active site, the selectivity stems from non-covalent interactions like hydrogen bonding between the morpholine/piperazine rings with LH2-specific Arg661, where the corresponding residue in LH1 and LH3 is Pro. Migration assays in the 344SQ lung adenocarcinoma cell line reveal that 13 shows anti-migration activity.
Post-Hydration Crosslinking of Ion Exchange Membranes to Control Water Content
Authors: Barnett Adam , Karnes John , Clemens Auston , Oakdale James , Molinero Valeria
Published: December 2022

Crosslinking is a common approach toward mitigating excess water uptake by ion exchange membranes. Most crosslinking reactions are performed when the ionomer is in anhydrous form, before the membrane self-segregates into hydrophilic and hydrophobic domains upon exposure to water. Here we use numerical and molecular simulations to investigate the prospect of crosslinking the polymer after casting and partial hydration of the membrane at subsaturated conditions. Such a process would allow the membranes to develop their nanosegregated morphology and establish well-connected but narrow water channels, while limiting further sorption of water. We find that post-hydration crosslinking of membranes has the ability to dramatically reduce membrane swelling. These results show that crosslinking after membrane casting and hydration may be a viable option for controlling water uptake. Further, we suggest chemical crosslinking strategies that may yield sufficiently high membrane gel fractions based on our analyses.
High Pressure Homogenization – An Update on its Usage and Understanding
Authors: Inguva Pavan , Grasselli Silvia , Heng Paul W.S.
Published: December 2022

Despite being a technology of several decades, high pressure homogenization (HPH) remains widely used in food and pharmaceutical industries, often as an essential unit operation in liquid product processing. Continual advances in the technology are made on multiple fronts, on equipment innovations by the manufacturers, new applications by users and advances in process understanding by multidisciplinary scientists alongside subject matter experts amongst industry practitioners. While HPH is comparatively simple conceptually, the homogenization process involves complex engineering physics which is influenced by the varied processing conditions and highly diverse inputs with each use-case requiring its own treatment. The successful application of a HPH process indubitably requires practitioners to draw upon insights from multiple domains and the optimization for each case. Thus, this timely review aims to outline the more recent trends and advancements in HPH process understanding and novel applications involving HPH from both academic and industrial perspectives.

Determinación del rendimiento de la biodegradación de residuos de aceite lubricante retenidos en bentonita usando el consorcio bacteriano oil eating microbes (Rodhococus, Pseudomonas y Bacillus)
Authors: Chirre Flores Jaqueline Heidy , Feliciano Muñoz Osiris , Robles Calderón Roberto
Published: December 2022

Los aceites que se utilizan como lubricantes en maquinaria, vehículos o equipos industriales se deterioran con el uso, es decir, pierden sus propiedades por efecto de las condiciones medioambientales, lo que da lugar a la formación de ácidos y compuestos de oxidación que pueden ser corrosivos y son considerados residuos peligrosos. Esta investigación busca determinar el rendimiento de la biodegradación del aceite lubricante automotriz usado utilizando el consorcio bacteriano oil eating microbes (Rhodococcus, Pseudomonas y Bacillus). Este se cuantificó por medio de la reducción de la cantidad de hidrocarburos totales de petróleo (HTP) presentes en la bentonita en cuatro pruebas experimentales. Se obtuvo como resultado la disminución de HTP en un 57 %, en las siguientes condiciones de operación del proceso: T = 35 ºC, pH = 7,0, agitación mecánica = 120 rpm, dilución de la arcilla contaminada en agua en una relación de 1 (arcilla): 3 (agua).

Authors: Nurhayati Yati
Published: December 2022

This study aims to dissect the concept of annulment of arbitral awards in several countries. Arbitration disputes are one of the options in resolving business disputes that are used in various countries in the world, one of which is Indonesia. Arbitration, both national and international, has a very important role in the business world which continues to develop, especially in the digital era. However, the arbitration award which has a final and binding nature still has a denial effort through the annulment of the award. In Indonesia, the provisions for the cancellation of arbitration are regulated in Article 70 of the Arbitration Law which has changed from the provisions before the birth of the Arbitration Law. This study uses a normative research method (comparative descriptive) which focuses on comparing the concept of annulment of arbitral awards in several countries in accordance with the laws and regulations in force in each country, not only discussing the rejection of the implementation of arbitral awards in comparison of two countries, the conditions for the cancellation of arbitral awards. national or international arbitral award. The results of the study showed that although arbitration applies in almost many countries, the provisions for the cancellation of arbitration awards in several countries are different.

Environmental Dynamism and Search Distance: Technology Search Efforts of Korean High-tech Electronics Firms
Authors:   Korean Academy Of Management, Kim Doyoon , Shin Dongyoub
Published: December 2022

In this paper, we explored the market and environmental factors that may drive an organization’s technology search efforts through patent applications under dynamic environments. Unlike previous studies which have mainly focused on the consequences of exploration and exploitation, this study draws attention to a more contextual perspective, as the antecedents of exploration and exploitation, to explain and to elaborate on organizational adaptation – i.e. exploration and exploitation. This study empirically investigated factors affecting organizations’ strategic choices for carrying out a distant search rather than a local search or factors driving a local search rather than a distant search. We hypothesized that different market and environmental factors, such as exogenous shock, volatility, and complexity, may also induce greater organizational search distance. First, this study explored exogenous shock affecting organizational adaptation not only exogenously but also endogenously. Next, the effect of market volatility has been examined for whether it suppresses organizational change. Last, environmental complexity has been established through organizations’ surroundings and an investigation was done for suspected effects on organizational decision-making. The results of our analysis of technology search processes in the Korean high-tech electronics industry from 1994 to 2008 showed that these three environmental factors affected the search distance when they explored new technology domains, as predicted in our hypotheses. General implications on organizational search processes for researchers and practitioners are discussed.
The Effect of Psychological Entitlement on Unethical Behavior: Testing the Moderating Effects of P-O Fit and P-J Fit and the Mediating Impact of Job Stress
Authors:   Korean Academy Of Management, Kim Hyung Jin , Shim Duk Sup
Published: December 2022

The current generation's sense of self-value and privilege are much higher than that seen in the previous generation and have manifested socially in the form of negative behaviors such as 'gapjil' and social dissatisfaction.
Because a large proportion of the current labor force belongs to the millennial generation or Generation Y, it is necessary to find a way to manage the problems caused by employee's psychological entitlement in the workplace.
However, only a few studies have been conducted on the impact of psychological entitlement in the workplace. As such, understanding of psychological entitlement in the job environment is limited. The purpose of this study is to explore how psychological entitlement impacts employees’ unethical behavior and to examine the mediating effect of job stress. It also tests whether person-organization fit and person-job fit moderate the relationship between psychological entitlement and job stress. The major findings are 1) psychological entitlement is positively associated with job stress; 2) person-organization fit and person-job fit have moderating effects on the relationship between psychological entitlement and job stress, implying that person-organization fit and person-job fit act as a buffer mitigating the negative effect of psychological entitlement; 3) psychological entitlement is positively linked to unethical behavior, 4) job stress partially mediates the relationship between psychological entitlement and unethical behavior, and 5) person-job fit negatively moderates the mediating effect of job stress in the relationship between psychological entitlement and unethical behavior. Thus, person-job fit decreases the influence of job stress in the psychological entitlement-unethical behavior linkage. Based on the results, the theoretical and practical implications are discussed, and recommendations for future research are provided.

Published: December 2022

The results of the effect of complex phytopreparations on blood parameters in the treatment of dyspepsia in young cattle are presented. Three groups of newborn Hereford calves with signs of dyspepsia were used as the research material. The first experimental group was given the developed preparation № 1 (bird cherry fruit, eleutherococcus rhizome, camomile flowers, probiotic) 2 times a day at 12-hour intervals at the rate of 2 ml/kg of live weight; the 2nd - was given the developed preparation № 2 (bergenia rhizome, fennel leaf, calendula flowers, probiotic) 2 times a day at 12-hour intervals at the rate of 2 ml/kg of live weight. Animals of the control group were not given the studied preparations and were treated according to the scheme adopted at the farm (they were given boiled water with NaCl 9 g/boiled water, pancreatin, tetracycline. Prior to the experiment, all clinical signs of dyspepsia were noted in sick calves. After the application of herbal preparations in the experimental groups in 7 days normalization of leukocytes by 60.4 and 48.7%, respectively, was observed. The number of erythrocytes in all studied groups was within the normal range, the level of hemoglobin in the control group was registered 10% lower than normal and 20.5% lower than in the second group of animals. Hematocrit in the experimental groups corresponded to the norm (35.2 and 38.7%, respectively), in the control group it exceeded the norm by 26% (p < 0.01). The content of sodium and potassium in the blood serum in the control group was reduced by 44 and 17.1%, respectively, and in the experimental groups it was within the reference values. In the experimental groups, positive dynamics of normalization of calcium-phosphorus ratio and iron was noted. Glucose level significantly (p < 0.05) increased by 2.7% in the 1st experimental group and by 3.9% in the 2nd group. The data obtained indicate high effectiveness of the preparations (90 and 100% respectively) and a positive effect on the physiological parameters of the calves, as well as on the consumer qualities of the products.

Authors: Fedina L. A. , Markova T. O. , Maslov M. V.
Published: December 2022

The information is given about the Chinese ladies'-tresses Spiranthes sinensis (Pers.) Ames (Orchidaceae Lindl.), which is a promising species for use in the floriculture under conditions of the Primorsky Territory. In this region, the Chinese ladies'-tresses is found in almost all areas, but the known present-day locations have low number of populations. This decorative, long-blooming orchid propagates well vegetatively, tolerates drought, severe soil compaction, and is long-lived in grasses. Like other meadow species of orchids, the Chinese ladies'-tresses can grow in sunny places and in the penumbra, in combination with accompanying small plants. Limiting factors include disturbance of natural habitats as a result of extreme natural phenomena and anthropogenic impact. New locations of S. sinensis in the Primorsky Territory are described. Field studies were conducted in 2018-2021 by route reconnaissance method. Description of habitats and morphometric parameters of Chinese ladies'-tresses, analysis of herbarium specimens (VLA, VBGI, MW, MHA, LE) of this plant in the Russian Far East was carried out. In the Primorsky Territory, new habitats of the Chinese ladies'-tresses have been identified and five cenopopopulations have been described. The area of the plots ranged from 8 to 936 m2, the number of flowering individuals was from 12 to 28 specimens, and the population density reached 5 specimens/m2. The height of a flowering plant can reach 64 cm. The species is not included in the Red Book of the Russian Federation (2008) or in the Red Book of the Primorsky Territory (2008), so it can be used in the region for landscaping as a beautiful flowering herbaceous plant.

The level of accuracy in determining the prediction of the provision of educational funding assistance is very important for the education agency. The large number of data on prospective beneficiaries can be processed into information that can be used as decision support in determining eligibility for education funding assistance. The data processing is included in the field of data mining. One method that can be applied in predicting the feasibility of receiving aid funds is classification. There are several classification algorithms, one of which is a decision tree. The famous decision tree algorithm is C4.5. The C4.5 algorithm can be applied in classifying prospective recipients of educational aid funds. This study uses datasets from student data of SMK Al Fattah Kertosono. The purpose of this study is to increase the accuracy of the C4.5 algorithm by applying adaboost in classifying students who deserve education funding and not, by comparing the results before and after applying adaboost. Validation in this study uses cross validation. While the measurement of accuracy is measured by the confusion matrix. The experimental results show that there is an increase in accuracy of 7.2%. The accuracy of the application of the C4.5 algorithm reaches 91.32%. While the accuracy of the application of the C4.5 algorithm with adaboost reached 98.55%.

Negative traits of bauxite residue (BR) include low shear strength, inconsistent compaction characteristics and dispersion, render it unsuited geomaterial for engineering applications. The present study aims at stabilizing BR with the combination of lime (L) and graphene oxide (GO) in suitable proportions and investigating their impact on improvement in engineering properties (viz., density, unconfined compressive strength (UCS), dispersion, and durability). Lime of 2-10% and GO of 0.05-0.1% dosages (% weight of BR) are selected for experimentation purpose. Results demonstrate that L and GO together, not the individual additive, is effective to stabilize BR. A substantial improvement in UCS from 710 kPa of raw BR to 3890 kPa after treating with 10% L and 0.1% GO with 60 days curing period has been observed. 6% L and 0.05% GO for strength only in the short-term, and 10% L and 0.05% GO in durability aspect in the long-term are found as optimum dosages. Drastic decline in turbidity from 453 to 83 NTU establishes that L (6%) and GO (0.05%) addition completely alleviates dispersion behavior in BR. Though GO addition is trivial, its effect on strength and durability enhancement of BR is significant. Cementitious gel formations and bonding mechanism leading to particle aggregations are evidenced as the reason behind the improvement in strength and durability of BR. To verify the applicability of amended BR, the obtained findings are compared vis-à-vis with standards, which illustrated that the amended BR could be an excellent resource material in road construction, especially in base or sub-base courses.

Follicular dendritic cell sarcomas (FDCS) are spindle cell lesions that are large, slow-growing masses in either nodal or  extranodal regions or both and originate from B-cell follicles of the lymph nodes. Most tumors originate from the cervical lymph nodes, but retroperitoneal and mediastinal origins have also been reported. Extranodal areas include soft tissues, skin, tonsils, gastrointestinal tract, liver, and spleen. The spleen is an uncommon location for an FDCS and for this reason, the tumor may be underdiagnosed or overlooked because of confusion with other solid tumors. In this study, we present a patient with a splenic FDCS who presented clinically with abdominal pain and diarrhea. The patient underwent a splenectomy and had an uneventful remission.

Published: December 2022

La competitividad y su relación con la ciencia es cada vez más estrecha en países en vías de desarrollo, pues en naciones desarrolladas es una constante en la implementación de políticas públicas de desarrollo. Medir la competitividad permitirá entender la situación actual de un determinado sector económico frente a otro, dentro de las fronteras nacionales o fuera de ellas. El propósito de esta investigación es analizar la eficiencia comercial de la malanga como uno de los productos alternativos de exportación no petrolera del país hacia los Estados Unidos. Lo anterior encuentra su base en el índice de ventaja relativa de exportaciones (VRE), describiendo la competitividad exportable de cuatro países. El resultado establece que Nicaragua y Ecuador son competitivos en la exportación de este tubérculo, mientras que México y República Dominicana no logran los niveles de los primeros en el mercado analizado, el cual tiene una proyección de consumo atractiva en el mediano plazo. Adicionalmente el VRE determina las ventajas del mercado estadounidense que han permitido incrementar las exportaciones de malanga ecuatoriana. Lo anterior refleja resultados en un sector que tradicionalmente ha sido dominado por productos históricos tradicionales que, en este caso, no han impedido destacar en un mercado que recién está conociendo su potencial.
