WOOD ANATOMY OF TREES AND SHRUBS FROM CHINA. I. OLEACEAE

Summary The wood anatomy of 34 species belonging to nine genera of Oleaceae, native or common ly cultivated in China, is described in detail, and a key to the identification of the genera is given. The diversity in wood structure supports the grouping of genera as based on a worldwide wood anatomical survey of the family by Esser and Van der Westen (1983) and Esser et al. (in preparation). Characters to separate these groups are type of imperforate tracheary ele ments (libriform fibres or fibre-tracheids), ves sel distribution and grouping (mainly solitary or mainly in multiples; in an oblique to den dritic pattern or not), presence or absence of vascular tracheids, presence or absence of pa renchyma bands (mostly marginal), and vessel wall sculpturing and intervessel pit size. Within Chionanthus s.1. (i.e., Linociera Sw. and Chionanthus L. s. s.) there is an abrupt and significant set of wood anatomical differences between the species previously treated in Lino ciera (diffuse-porous, small intervessel pits, spi ral vessel wall thickenings and vascular tracheids absent) and Chionanthus retusus (vessels in an oblique to dendritic pattern, large intervessel pits, spiral vessel wall thickenings and vascular tracheids present). In Olea a similar wood ana tomical diversity exists, but here the differences are less abrupt. In its ecological wood anatomy, the Oleaceae from China largely follow general trends: the taxa from mesic (sub)tropical provenances tend to have longer vessel members, and wider and less frequent vessels than their relatives from more temperate or seasonally dry habitats; spi ral vessel wall thickenings are largely restricted to the temperate species.
Experimental investigation of high frequency combustion instability in cryogenic oxygen-hydrogen rocket engines

Self-sustaining pressure oscillations in the combustion chamber, or combustion instability, is a commonly encountered and potentially damaging phenomenon in liquid propellant rocket engines (LPREs). In the high-frequency variety of combustion instability, the pressure oscillations take on the form and frequency of an acoustic resonance mode of the combustion chamber volume. The most common mode in naturally occurring instability, and also the most destructive, is the first tangential mode, with acoustic gas oscillations oriented transversally to the direction of propellant injection. The instability is driven by the coupling between acoustic oscillations and unsteady energy release from combustion. The mechanisms through which injection and combustion firstly respond to the acoustic field, and secondly feed energy back into the acoustic field have not yet been fully characterised.
Associations among Orthodontic History, Psychological Status, and Temporomandibular-Related Quality of Life: A Cross-Sectional Study

Objectives This cross-sectional study aimed to evaluate the associations among orthodontic history, psychological status, and temporomandibular-related quality of life. Methods A questionnaire was developed and distributed to students in a local college, containing questions about demographic information, the Patient Health Questionnaire-4 (PHQ-4), the Fonseca anamnestic index, and the Oral Health Impact Profile for Temporomandibular Disorders (OHIP-TMD). The respondents were divided into with orthodontic history (OS) group and without OS group. Binary logistic regression and multiple linear regression were performed for statistical analysis. Results A total of 531 valid questionnaires were collected, covering 161 participants with OS and 370 participants without OS. No statistically significant differences were observed in the scores of PHQ-4 between the two groups. There was statistical difference in the prevalence of TMD (with OS group, 54.66%; without OS group, 40.81%) and the mean value ( ± standard deviations) of the scores of OHIP-TMD (with OS group, 9.64 ± 12.36; without OS group, 6.64 ± 10.79) (p < 0.05). After adjusting confounding factors, participants with OS have worse temporomandibular-related quality of life and a higher risk of having TMD than the participants without OS. Conclusions Orthodontic history was related with the higher prevalence of TMD and worse temporomandibular-related quality of life, but not related with psychological distress, and the cause-and-effect relationship needs further exploration.
Kinetic Control of Anion Stoichiometry in Hexagonal BaTiO3

The cubic oxyhydride perovskite BaTiO3−xHx, where the well-known ferroelectric oxide BaTiO3 is partially hydridized, exhibits a variety of functions such as being a catalyst and precursor for the synthesis of mixed-anion compounds by utilizing the labile nature of hydride anions. In this study, we present a hexagonal version, BaTi(O3−xHx) (x < 0.6) with the 6H-type structure, synthesized by a topochemical reaction using hydride reduction, unlike reported hexagonal oxyhydrides obtained under high pressure. The conversion of cubic BaTiO3 (150 nm) to the hexagonal phase by heat treatment at low temperature (950~1025 °C) using a Mg getter allows the introduction of large oxygen defects (BaTiO3−x; x − 0.28) while preventing the crystal growth of hexagonal BaTiO3, which has been accessible at high temperatures of ~1500 °C, contributing to the increase of the hydrogen content. Hydride anions in 6H-BaTiO3−xHx preferentially occupy face-sharing sites, as do other oxyhydrides.
A Review on Current Strategies for Extraction and Purification of Hyaluronic Acid

Since it is known that hyaluronic acid contributes to soft tissue growth, elasticity, and scar reduction, different strategies of producing HA have been explored in order to satisfy the current demand of HA in pharmaceutical products and formulations. The current interest deals with production via bacterial and yeast fermentation and extraction from animal sources; however, the main challenge is the right extraction technique and strategy since the original sources (e.g., fermentation broth) represent a complex system containing a number of components and solutes, which complicates the achievement of high extraction rates and purity. This review sheds light on the main pathways for the production of HA, advantages, and disadvantages, along with the current efforts in extracting and purifying this high-added-value molecule from different sources. Particular emphasis has been placed on specific case studies attempting production and successful recovery. For such works, full details are given together with their relevant outcomes.
An Unethical Organizational Behavior for the Sake of the Family: Perceived Risk of Job Insecurity, Family Motivation and Financial Pressures

In organizations, unethical behaviors are pervasive and costly, and considerable recent research attention has been paid to various types of workplace unethical behavior. This study examines employees’ behaviors that are carried out for the benefit of one’s family but violate societal and organizational moral standards. Drawing upon the self-maintenance and bounded ethicality theories, this study examines the engagement of unethical organization behaviors (UOB) in the name of the family during the COVID-19 pandemic. It examines the influence of job instability and the mediating role of family financial pressure and family motivation. A total of 770 employees in hotels and travel agents in Egypt were targeted, and the data were analyzed using structural equation modeling. The results posit that perceived risk of job insecurity predicts engagement in unethical organizational behaviors, while intentions of UOB increase by high family motivation and financial pressures. Toward the end of this paper, a discussion on the theoretical and practical implications and are presented.
The Preference Survey Module: New Evidence on Social Preferences from Tehran

IZA DP No. 15006 JANUARY 2022 The Preference Survey Module: New Evidence on Social Preferences from Tehran* We provide new evidence on the extent that survey items in the Preference Survey Module and the resulting Global Preference Survey measuring social preferences − trust, altruism, positive and negative reciprocity − predict behavior in corresponding experimental games outside the original student sample from Bonn, Germany. Our results, which are based on a replication study in Tehran, Iran, are somewhat mixed. While quantitative items considering hypothetical versions of the experimental games correlate significantly and economically meaningfully with individual behavior, none of the qualitative items show significant correlations. The only exception is altruism where results correspond more closely to the original findings. JEL Classification: C81, C83, C90, D01, D03
Indonesian Stock Price Prediction using Deep Learning during COVID-19 Financial Crisis

This research paper aims to use the deep learning model Long Short-Term Memory (LSTM) for the stock prediction model under the financial crisis of COVID-19. The financial impact of the COVID-19 has brought many of the world's indexes down. The impact of the financial crisis is even riskier for an emerging country such as Indonesia where foreign investors tend to take out their investments in emerging countries in financial crisis events. The application of deep learning in financial time series applications such as stock price prediction has been researched extensively. This study used the (Bidirectional LSTM) BiLSTM model which is a variation of the LSTM model to predict stock closing price. The stock prediction is applied to a selected company from the Indonesian stock market using historical prices. The model is then evaluated using metrics Mean Absolute Percentage Error (MAPE) and Symmetric Mean Absolute Percentage Error (SMAPE). A graphical comparison between the actual price and predicted price of the stock is charted to study the stock price movement. To study the impact during COVID-19 on the stock prices, an intervention analysis is conducted along with the Wilcoxon model. The stock price prediction model can forecast the price of stocks before and during the financial crisis with minimal error. The intervention analysis result showed that health sectors have a positive effect while other sectors such as transportation, finance, information technology, and entertainment have a negative effect during the financial crisis of COVID-19. Being able to analyze and study the stock price movement of stocks is beneficial to investors in understanding the impact of the financial crisis on some industries and the behavior of certain stocks or industries under the circumstances which can lead to alternate investment strategies and decision making.
Silver Nanoparticles Inhibit Metastasis of 4T1 Tumor in Mice after Intragastric but Not Intravenous Administration

The potential anticancer activity of different silver nanoformulations is increasingly recognized. In the present work, we use the model of 4T1 tumor in BALB/ccmdb immunocompetent mice to analyze the impact of citrate- and PEG-coated silver nanoparticles (AgNPs) on the development and metastatic potential of breast cancer. One group of mice was intragastrically administered with 1 mg/kg body weight (b.w.) of AgNPs daily from day 1 to day 14 after cancer cells implantation (total dose 14 mg/kg b.w.). The second group was intravenously administered twice with 1 or 5 mg/kg b.w. of AgNPs. A tendency for lowering tumor volume on day 21 (mean volumes 491.31, 428.88, and 386.83 mm3 for control, AgNPs-PEG, and AgNPs-citrate, respectively) and day 26 (mean volumes 903.20, 764.27, and 672.62 mm3 for control, AgNPs-PEG, and AgNPs-citrate, respectively) has been observed in mice treated intragastrically, but the effect did not reach the level of statistical significance. Interestingly, in mice treated intragastrically with citrate-coated AgNPs, the number of lung metastases was significantly lower, as compared to control mice (the mean number of metastases 18.89, 14.90, and 8.03 for control, AgNPs-PEG, and AgNPs-citrate, respectively). No effect of AgNPs treatment on the number of lung metastases was observed after intravenous administration (the mean number of metastases 12.44, 9.86, 12.88, 11.05, and 10.5 for control, AgNPs-PEG 1 mg/kg, AgNPs-PEG 5 mg/kg, AgNPs-citrate 1 mg/kg, and AgNPs-citrate 5 mg/kg, respectively). Surprisingly, inhibition of metastasis was not accompanied by changes in the expression of genes associated with epithelial–mesenchymal transition. Instead, changes in the expression of inflammation-related genes were observed. The presented results support the antitumor activity of AgNPs in vivo, but the effect was limited to the inhibition of metastasis. Moreover, our results clearly point to the importance of AgNPs coating and route of administration for its anticancer activity. Finally, our study supports the previous findings that antitumor AgNPs activity may depend on the activation of the immune system and not on the direct action of AgNPs on cancer cells.
Effects of Tannic Acid Supplementation on Growth Performance, Oocyst Shedding, and Gut Health of in Broilers Infected with Eimeria Maxima

Simple Summary E. maxima, an intracellular protozoan parasite propagating in the jejunum, can cause severe negative effects on growth and gut health of chickens. Tannic acid (TA), a polyphenol compound that can precipitate proteins, was hypothesized to control E. maxima infection and attenuate its negative effects in broilers due to their antimicrobial, antioxidative, and anti-inflammatory effects. Our study showed that supplementation of TA reduced oocyst shedding of E. maxima. Supplementation of TA at the level of 500 to 2750 mg/kg reduced gut permeability, increased nutrient digestibility, and improved intestinal development in broilers infected with E. maxima. However, supplementation of 5000 mg/kg TA showed anti-nutritional effects including reducing growth performance, increasing gut permeability, and decreasing nutrient digestibility in broilers infected with E. maxima. In summary, supplementation of TA at the level of 500 to 2750 mg/kg showed potential as an anti-coccidial agent by decreasing oocyst shedding and improving nutrient digestibility and intestinal integrity in broilers infected with E. maxima. Abstract The purpose of this study was to evaluate effects of tannic acid (TA) on growth performance, fecal moisture content, oocyst shedding, gut permeability, lesion score, intestinal morphology, apparent ileal digestibility, and the antioxidant and immune system of broilers infected with Eimeria maxima. A total of 420 one-day-old broilers were distributed to five treatments with seven replicates of 12 birds. The five treatments were the (1) sham-challenged control (SCC; birds fed a control diet and administrated with PBS); (2) challenged control (CC; birds fed a control diet and inoculated with E. maxima); (3) tannic acid 0.5 (TA0.5; CC + 500 mg/kg TA); (4) tannic acid 2.75 (TA2.75; CC + 2750 mg/kg TA); and (5) tannic acid 5 (TA5; CC + 5000 mg/kg TA). The TA2.75 group had significantly lower gut permeability compared to the CC group at 5 days post-infection (dpi). Supplementation of TA linearly reduced oocyst shedding of E. maxima at 7 to 9 dpi (p < 0.05). At 13 dpi, the TA2.75 group had significantly greater apparent ileal digestibility (AID) of dry matter (DM) and organic matter (OM) compared to the CC group. At 13 dpi, supplementation of TA linearly increased jejunal villus height (VH). Thus, this study showed that supplementation of TA at levels of 500 to 2750 mg/kg has the potential to be an anti-coccidial agent against E. maxima in broilers.
Impact of Pavement Thickness on Load Response of Perpetual Pavement

This thesis studies the performance of perpetual pavement structures constructed by the Ohio Department of Transportation. The pavement responses, collected from sensors installed in three separate perpetual pavement test sections on U.S. Route 23 in Delaware, Ohio during controlled vehicle load testing, were the main analysis for the study. To complement the pavement responses, a software analysis of the test sections was performed using PerRoad. The main pavement responses measured by test section instrumentation were strain at the bottom of the asphalt layer as well as in the base layer of the asphalt structure, subgrade pressure, pavement deflection, and subgrade deflection. Pavement responses were compared with fatigue endurance thresholds in order to evaluate the longevity of the pavement test sections. Additionally, the influences of several variables, including axle configuration, speed, and tire pressure, were analyzed to further understand their effects on pavement responses. Although controlled vehicle load testing was conducted during periods of colder temperatures, it was discovered that all of the pavement responses analyzed for the three sections were less than their respective fatigue endurance thresholds. Additionally, speed and axle configuration had a significant influence on the pavement responses. As testing speeds were increased the pavement responses decreased in magnitude. Furthermore, testing utilizing a tandem axle truck with dual tires produced reduced pavement responses in comparison with testing utilizing a single axle truck with wide-based tires even though the tandem axle truck carried a greater load. Tire pressure did not have a significant effect on pavement responses recorded in lower portions of the pavement structure. The PerRoad analysis performed, using inputs corresponding to the U.S. Route 23 test sections, revealed that, in theory, all three of the test sections would have in-service lives in excess of their design life of 50 years. An optimized pavement thickness for perpetual pavement systems in Ohio was not recommended due to a need for controlled vehicle load testing to be conducted during warmer periods since pavement responses are typically greater at higher pavement temperatures.
Comparative study on water impact problem

This paper presents a comparative numerical study for the water impact problems due to dropping of triangular wedges or ship sections. In the numerical investigation, both the dynamic mesh technique and immersed boundary method adopting fixed Cartesian grids have been adopted in order to conform to the motion of the structure. For the former, a multiple-phase solver with the volume of fluid for identifying the free surface is implemented. In the simulation using this method, both the compressible and incompressible solvers have been considered to explore the role of the compressibility. For the latter, an in-house immersed boundary method, in which a generalized equation is developed to govern the motion of different phases (air, water and solid) and a level-set method is adopted to identify the free surface & body surfaces. Different cases with different dropping speed have been considered in the investigation and the results are compared with the experimental data for the comparative study on the water impact problem.
Difluoromethylornithine (DFMO) Enhances the Cytotoxicity of PARP Inhibition in Ovarian Cancer Cells

Ovarian cancer accounts for 3% of the total cancers in women, yet it is the fifth leading cause of cancer deaths among women. The BRCA1/2 germline and somatic mutations confer a deficiency of the homologous recombination (HR) repair pathway. Inhibitors of poly (ADP-ribose) polymerase (PARP), another important component of DNA damage repair, are somewhat effective in BRCA1/2 mutant tumors. However, ovarian cancers often reacquire functional BRCA and develop resistance to PARP inhibitors. Polyamines have been reported to facilitate the DNA damage repair functions of PARP. Given the elevated levels of polyamines in tumors, we hypothesized that treatment with the polyamine synthesis inhibitor, α-difluoromethylornithine (DFMO), may enhance ovarian tumor sensitivity to the PARP inhibitor, rucaparib. In HR-competent ovarian cancer cell lines with varying sensitivities to rucaparib, we show that co-treatment with DFMO increases the sensitivity of ovarian cancer cells to rucaparib. Immunofluorescence assays demonstrated that, in the presence of hydrogen peroxide-induced DNA damage, DFMO strongly inhibits PARylation, increases DNA damage accumulation, and reduces cell viability in both HR-competent and deficient cell lines. In vitro viability assays show that DFMO and rucaparib cotreatment significantly enhances the cytotoxicity of the chemotherapeutic agent, cisplatin. These results suggest that DFMO may be a useful adjunct chemotherapeutic to improve the anti-tumor efficacy of PARP inhibitors in treating ovarian cancer.

Inducing the growth and flowering of caraway (Carum carvi L.) plant

This study was conducted during the 2019/2020 and 2020/2021 seasons at the Farm of Medicinal and Aromatic Plants Research Department in El-Kanater El-Khairia to evaluate the effect of glycine and tryptophan, each of them alone, at concentrations of 50, 100, and 150 ppm on vegetative growth, fruit yield, oil production, and plant hormones of caraway plants ( Carum carvi L.). The results are summarized as follows: caraway plants showed a positive response to the foliar application by glycine and tryptophan. The plant that received tryptophan at 150 ppm has the highest vegetative growth, denoted as plant height and the number of branches/ plant, and produced the highest number of umbels per plant and fruit yield compared with other treatments in the two seasons. The high concentration of glycine or tryptophan (150 ppm) significantly increased the essential oil percentage compared to the control in both seasons. The application of tryptophan at a concentration of 150 ppm recorded the highest percentage of the main constituent of the essential oil (carvone). Moreover, it also affected some plant hormones such as gibberellin, indole acetic acid, and abscisic acid.
