Brillouin scattering studies of ordered Pb(Sc1/2Nb1/2)O3 crystal with vacancies

Abstract Pb(Sc1/2Nb1/2)O3 (PSN) with a perovskite structure is a well-known ferroelectric material. The rapidly quenched PSN (PSN-D) shows a B-site disordered structure, and exhibits the noncanonical relaxor behavior with Tmax=around 351 K. The well-annealed PSN (PSN-O) exhibits a B-site 1:1 ordered structure, and undergoes a normal ferroelectric phase transition at TC= about 346 K, while, the introduction of vacancies may lead to the broadening of dielectric peak with frequency dispersion down to low temperatures, typical of relaxor nature. It was reported that as-sintered ordered PSN (PSN-OV) with Pb/oxygen vacancies exhibits relaxor ferroelectric behavior with TC= about 292 K. In this work, the elastic anomaly of a longitudinal acoustic (LA) mode and the central peak of a PSN-OV crystal were studied by Brillouin scattering. The temperature dependences of the frequency shift and the width of the LA mode along the [100] direction were investigated. A broad elastic anomaly and a broad slowing down of the relaxation time were observed at the ferroelectric phase transition. The elastic anomaly of PSN-OV is compared with those of PSN-D and PSN-O crystals reported in our previous studies. It is found that the relaxor nature of PSN-OV caused by vacancies is stronger than that of PSN-D caused by the B-site disorder.
DNA DAMAGE INDUCED BY OCCUPATIONAL EXPOSURE TO COPPER OXIDE NANOPARTICLES

Copper oxide nanoparticles (CuO NPs) have a widespread use in industry, chemistry, in production of electronic devices and as an antimicrobial agent. Although copper is an important biogenic element, CuO NPs are toxic with the ability to induce oxidative stress, apoptosis, cell cycle arrest or DNA damage. For humans, the inhalation route is the most common way of exposure to CuO NPs. In the body, CuO NPs may be either deposited in the lungs, or transported to other organs. Their presence usually causes oxidative stress or inflammatory responses, consequently leading to DNA damage. In this study, we investigated the effect of CuO NPs inhalation on DNA damage in a group of researches conducting animal exposure experiments. The subjects were exposed to various metal oxide nanoparticles, including CuO NPs, by inhalation for an average of 4.9 ± 0.4 years. The average mass concentration of Cu in the air during the experiment was 7.3 ± 3.2 ng/m3. Subjects not exposed to nanoparticles served as a control group. We applied micronucleus assay using Human Pan Centromeric probes to detect DNA damage and to distinguish between the frequency of centromere positive (CEN+) and centromere negative (CEN−) micronuclei (MN) in the binucleated cells. We did not find differences between both groups for either mean MN frequency (10.38 ± 2.50 vs. 11.88 ± 3.01 MN/1000 binucleated cells), or CEN+/CENratio (58%/42% vs. 55%/45%), for the exposed and controls, respectively. In conclusion, inhalation of CuO NPs at this low-level exposure had no effect on chromosomal losses and/or breaks.
A deep learning-based quantitative computed tomography model for predicting the severity of COVID-19: a retrospective study of 196 patients

Background The assessment of the severity of coronavirus disease 2019 (COVID-19) by clinical presentation has not met the urgent clinical need so far. We aimed to establish a deep learning (DL) model based on quantitative computed tomography (CT) and initial clinical features to predict the severity of COVID-19. Methods One hundred ninety-six hospitalized patients with confirmed COVID-19 were enrolled from January 20 to February 10, 2020 in our centre, and were divided into severe and non-severe groups. The clinico-radiological data on admission were retrospectively collected and compared between the two groups. The optimal clinico-radiological features were determined based on least absolute shrinkage and selection operator (LASSO) logistic regression analysis, and a predictive nomogram model was established by five-fold cross-validation. Receiver operating characteristic (ROC) analyses were conducted, and the areas under the receiver operating characteristic curve (AUCs) of the nomogram model, quantitative CT parameters that were significant in univariate analysis, and pneumonia severity index (PSI) were compared. Results In comparison with the non-severe group (151 patients), the severe group (45 patients) had a higher PSI (P<0.001). DL-based quantitative CT indicated that the mass of infection (MOICT) and the percentage of infection (POICT) in the whole lung were higher in the severe group (both P<0.001). The nomogram model was based on MOICT and clinical features, including age, cluster of differentiation 4 (CD4)+ T cell count, serum lactate dehydrogenase (LDH), and C-reactive protein (CRP). The AUC values of the model, MOICT, POICT, and PSI scores were 0.900, 0.813, 0.805, and 0.751, respectively. The nomogram model performed significantly better than the other three parameters in predicting severity (P=0.003, P=0.001, and P<0.001, respectively). Conclusions Although quantitative CT parameters and the PSI can well predict the severity of COVID-19, the DL-based quantitative CT model is more efficient.
Analysis on the Spatial Distribution and Evolutionary Trends of Farmers’ Forestry Income in China

With regard to the implementation of the Collective Forestry Tenure Reform in China, the proportion of forestry income in farmers’ total family income has gradually increased with rapid increases observed in some provinces. Due to these regional disparities, it is important to analyze the spatial distribution and evolutionary trends of farmers’ forestry income to uncover the underlying factors for the existing distribution and note gradual changes from the perspective of economic geography. When spatial distribution and evolutionary trends of farmers’ forestry income data from 31 provinces from 2000 to 2012 were analyzed, we found that farmers’ forestry income during the 13-yr period grew quickly, but the disparities between the highest and lowest income rates gradually widened as large increases in income within a few provinces constituted the bulk of the overall increase across China. We attribute the observed spatial distribution and evolutionary trends to an imbalanced distribution of forestry resources, varying forest species, complicated forestry ownership, multiple forestry policies, differences of labor, and forestry investment.
IDENTIFICATION AND EVALUATION OF DIPLOGYNY IN CLEMENTINE (CITRUS CLEMENTINA) FOR USE IN BREEDING

Seedlessness is an important trait in citrus cultivars for the fresh fruit market. It can be obtained by selection of self-incompatibility and sterility genes or by triploid methodology. Auto-incompatibility phenomena induce sterility but cross pollinations restore fertility. INRA and CIRAD-FLHOR are exploring triploid methodology to create new hybrids for diversification of the easy peeler citrus group. One of the possibilities is to select for spontaneous triploids occurring naturally in citrus progenies. These result from gametic cell fusions between a haploid gamete and an unreduced diploid gamete. We crossed three selections of clementine and a mandarin with different citrus species. Considering that the unbalanced level of ploidy between endosperm cells and embryo cells could affect seed development, we screened seeds, and extracted embryos which were then cultivated in vitro. From 99 triploid hybrids, we saved 88 by macro-grafting. We determined the parental origin of diplogamy for 72 triploid hybrids using isozymes. We have found that 2n ovum production (diplogyny) is very frequent, and 2n pollen production (diploandry) is a rare event (less than 2%). A few triploid hybrids have started to fruit. Comparison of seed yield per fruit for triploid hybrids and their genitors showed a dramatic decrease of female fertility leading most of the time to total sterility. Pollen of triploid hybrids was totally sterile. (Resume d'auteur)
Analysis of the anatomic variations of the ethmoid roof among Saudipopulation: A radiological study

The olfactory fossa (OF) is a depression in the anterior cranial cavity whose floor is formed by the cribriform plate of ethmoid, bounded laterally by the lateral lamella of cribriform plate and medially by crista galli. Keros categorized the olfactory fos-sa depth into 3 types. For a successful endoscopic sinus surgery, the surgeons should pay attention to the details when dealing with the complex anat-omy of the paranasal sinuses (PNS) and skull base. The aim of this study was to describe the distribution of Keros classification of the height of ethmoid roof among Saudi population by using multidetector computed tomography (MDCT). This was a retrospective study conducted on 511 pa-tients (360 males and 151 female) referred for MDCT assessment of PNS over a two-year period. The mean age of our patients was 34.47± 10.69 years, aged between 18 and 79 years. Patients with nasal trauma, surgeries or any pathological diseases affecting the ethmoid roof were excluded from the study. Keros type II was the commonest presentation observed in 53.2% of cases, followed by type I in 12.5%, then type III in 11.7% of cases. Out of the 511 patients analyzed, 115 (22.5%) cas-es had asymmetry (different types of OF) on both sides. Conclusion: The majority of studied Saudi adult population showed Keros type II (53.3%), followed by type I (12.5%). Keros type III was seen in 11.7% among the studied population.
Faecal microbiota transplantation: indications, evidence and safety

SUMMARY The human gut contains many species of microorganisms, many of which have a role in maintaining good health. The gut microbiota can be affected by diet, diseases and drugs, especially antibiotics. Faecal microbiota transplantation involves transplanting faecal material from a healthy person to a patient, with the aim of treating disease. It is a recommended treatment option for patients with recurrent or refractory Clostridioides difficile as it has a cure rate over 90%. There is evidence that faecal microbiota transplantation can induce remission in ulcerative colitis, however maintenance of remission data are lacking. For other diseases it currently should not be used outside a clinical trial. Stool donors have to be healthy and are screened for a range of diseases. As faecal material is usually transplanted during colonoscopy, the recipient must have bowel preparation before the procedure. Adverse effects are mainly gastrointestinal and usually resolve in the week following transplantation. There are limited data on long-term safety.
Video/Computer Game Addiction among University Students in Ghana: Prevalence, Correlates and Effects of Some Demographic Factors

Background: This study represented the first investigation of video/computer game addiction in Ghana and Africa. We investigated the prevalence of video game addiction and some of its correlates. In addition, the effects of some demographic factors on video game addiction were examined. Methods: A sample of Ghanaian University students (n= 263) from three public universities in Ghana were randomly selected. 136 were males whereas 127 were females. The mean age of the participants was 21.65 years. Results: We found that 12.2% (n=32) of the total sample were addicted to playing video games when a monothetic approach was used (i.e., every criterion for video game addiction were met), while 31.2% (n=82) of the total sample were addicted to playing video games when a polythetic approach was used (i.e., half of the criteria for video game addiction were met). Males spent more time and were addicted to playing video games than females. Our findings also revealed that students who played online games reported being addicted to playing video/computer games than offline gamers. Video game addiction was positively related to time spent playing video games and depression. In contrast, video game addiction was negatively related to self-esteem. No relationship was found between video game addiction and life satisfaction. Conclusions: Our high prevalence rates suggest that video game addiction is a problematic issue among the Ghanaian University students and needs proper attention from researchers and clinicians.
Effect of Digestate on Soil Organic Carbon and Plant-Available Nutrient Content Compared to Cattle Slurry and Mineral Fertilization

Digestate contains many valuable nutrients, including nitrogen (N), phosphorus (P), and potassium (K); however, it is characterized by relatively little organic matter. The objective of this study was to assess the four-year impact of digestate (Dig) application, digestate + straw (Dig + St), cattle slurry (Csl), and mineral fertilization (NPK) on soil organic carbon (SOC), total nitrogen (TN), mineral N (Nmin), and the content of plant-available P and K. Fertilization did not have any significant influence on SOC, TN, and SOC/TN parameters. Yet, in comparison with control, there was an upward trend in the concentration of SOC and TN in the topsoil, where fertilizers were applied. In contrast to SOC and TN, fertilizer treatment significantly affected the content of P, K, and Nmin, and the differences depended on the soil depth and the fertilizer used. On average, the highest content of P was obtained in Csl treatment, but the highest content of K was observed in Dig + St. The effect of treatment on Nmin in spring was as follows: NPK = control < Csl = Dig + St < Dig. Straw plowing increased the bio-immobilization of N with digestate and, at the same time, lowered the content level of nitrates in soil.
A comparison of macrophage migration inhibitory factor with C reactive protein in diabetic hypertensive patients with myocardial infarction that underwent primary percutaneous coronary intervention

The inflammatory response is one of the complications of diabetic hypertensive patients with myocardial infarction (MI). The purpose of this study was to determine the diagnostic value of macrophage migration inhibitory factor (MIF) compared with high sensitivity C reactive protein (hs-CRP) in diabetic hypertensive patients presented with MI; and to determine the concomitant association between these factors in MI patients. For this purpose, 100 patients with MI were categorized into four groups, according to the existence of diabetes mellitus (DM) and/or hypertension (HTN), with 38 subjects with normal angiography considered as the control group. The levels of MIF and hs-CRP were estimated quantitatively using a sandwich enzyme-linked immunosorbent assay and a particle-enhanced immune turbidimetric assay, respectively. In addition, lipid profiles, hematological indicators, and certain clinical features were compared among the studied groups. The levels of MIF and hs-CRP increased significantly in MI patients compared to the controls (p<0.05). Additionally, the levels of MIF differed significantly between all MI
Structure and Properties of Liquid Fe‐C Alloys at High Pressures by Experiments and First‐Principles Calculations

It is believed that the core formation processes sequestered a large majority of Earth’s carbon into its metallic core. Incorporation of carbon to liquid iron may significantly influence its properties under physicochemical conditions pertinent to the deep magma ocean and thus the chemical evolution of terrestrial planets and moons. Compared to available experimental data on the physical properties of crystalline iron alloys under pressure, there is a remarkable lack of data on the properties of liquid iron‐rich alloys, due to experimental challenges. Here we review experimental and computational results on the structure and properties of iron or iron‐nickel liquids alloyed with carbon upon compression. These laboratory data provide an important foundation on which the interpretation of ultrahigh pressure laboratory data and the verification of theoretical data will have to be based. The low‐pressure data can be used to validate results from theoretical calculations at the same conditions, and high‐pressure calculations can be used to estimate and predict liquid properties under core conditions. Availability of the liquid properties of Fe‐C liquids will provide essential data for stringent tests of carbon‐rich core composition models for the outer core. 4
Impact of Online Reviews on Consumer’s Hotel Booking Intentions: Does Brand Image Mediate?

Abstract The recent trend suggests that people are more inclined to online hotel reviews to take online hotel booking decisions. The present study argues that when consumers are exposed to online hotel reviews, it draws an impression of the hotel brand in the mind of consumers, resulting in influence their hotel booking intentions. The current study determines the mediation effects of brand image between credible online hotel reviews and consumers’ hotel booking intentions. To ascertain the uni-dimensionality of the scales, the present study executes exploratory factor analysis. The ensure the internal consistency of the variable scales, the study determines Cronbach’s alpha. To measure the mediation effects, the present study performs structural equation modeling bootstrapping method. Data analysis reveals that marketers should look at hedonic brand image, which ultimately influences consumers’ hotel booking intentions. This is a unique study that ascertains the type of brand image that actually mediates between the impact of online hotel reviews and consumers’ hotel booking intentions. In addition, the paper furnishes theoretical background on how people interpret online hotel reviews and its effects.

Pengaruh Suplementasi dan Proteksi Minyak Biji Kapuk Terhadap Fermentabilitas Ruminal Rumput Gajah pada Sapi Secara In Vitro

(The effect of supplementation and protection of kapok seed oil on in vitro ruminal fermentability of elephant grass) ABSTRACT . The purpose of this research was to study the interaction between supplementation and protection of kapok seed oil (KSO) influence on in vitro digestibility and ruminal fermentability products of elephant grass. Material used were elephant grass, kapok seed oil, KOH and CaCl 2 reagens and cattle rumen fluids. Completely randomized design (CRD) was used with two factorial pattern 3 x 5 with 2 replications, first factor was supplementation of KSO consist of 3 levels: 5% (S1); 10% (S2); and 15% (S3), respectively. Second factor was protection consist of 5 levels: 0% (P0); 25% (P1); 50% (P2); 75% (P3) and 100% (P4); also control treatment without supplementation and protection of KSO (S0P0). The result of this research showed there was no interaction between supplementation and protection of KSO on digestibility of elephant grass. The highest In vitro Dry Matter Digestibility (IVDMD) and In vitro Digestibility of Organic Material (IVDOM) reached by control treatment, 55,17% and 54,27%, respectively. The results of this research showed influence of interaction between supplementation and protection of KSO on VFA and NH 3 production (P<0.05). The highest VFA and NH 3 production reached by 10% supplementation and 25% protection were 152,5 and 6,50 mM. The conclusion of this study showed that supplementation and protection of KSO was not effecting ruminal fermentation, but decreasing in vitro digestibility of elephant grass.
A Student-Led Elective Provides Quality Improvement Feedback for a Required Compounding Course

Objective. To implement an advanced elective compounding course where pharmacy students conduct investigations to improve compounding-related issues that were subsequently evaluated in a required compounding course. Methods. The elective compounding course required students to engage in self-directed learning, critical thinking, creation and evaluation of laboratory data, and self- and group reflection. Students researched and developed “solutions” to compounded preparation problems, and their solutions were tested in the next iteration of a required compounding course. For example, students in the elective course identified sources of potency variability in a ketoprofen Pluronic organogel (PLO) emulsion preparation. The students identified six variables and executed an investigative action plan. They considered all data collected and proposed a method to reduce potency variation. The recommended solution was implemented in the next offering of a required compounding course and the potency variability results were compared to the previous required course’s results. Results. The mean ketoprofen PLO emulsion potency achieved in the required course prior to implementing the elective course recommendation was 129% (SD 21%), n=158. After the recommended change from elective course was implemented, the mean potency was 118% (SD 21%), n=131. Conclusion. The teaching methods and activities conducted in the elective course provided students with a deeper level of learning and understanding of compounding science, while providing practical experience in scientific research methodology. The course also provided a cyclic quality improvement feedback mechanism for the required course.
Performance of transplanted maize (Zea mays) under varying age of seedling and method of nursery raising in the midlands of eastern region

Field experiments were conducted at ICAR Research Complex for Eastern Region Farm, Patna during winter (rabi) season of 2008-09, 2009-10 and 2010-11 to study the performance of maize (Zea mays L.) crop under transplanted condition as affected by different age of seedlings and methods of nursery raising. Transplantation of five weeks old seedlings and nursery raised on sand culture as well as on raised bed recorded more plant height, leaf length, dry matter accumulation/plant and yield attributes over other methods of raising seedlings and varying age group. After transplantation mortality of seedlings in the main field was minimum reported with 5 week old seedlings (5.8%) as well as seedlings raised under sand culture and raised bed method (5.2% and 5.8%, respectively) during the years of experimentation. Transplanting of five weeks old seedlings raised either in sand culture or on raised beds produced significantly higher grain yield (6.71 and 6.36 tonnes/ha, respectively) over other treatments. Root volume and leaf area index (LAI) at 90 days after transplanting (DAT) were also higher in seedlings raised under sand culture (1.03and 72.2 cm3) and raised bed conditions (0.99 and 69.8 cm3) in nurseries. However, 5 week old seedlings grown either on sand culture or on raised bed resulted higher net income (Rupees 23 074 and 22 334/ha respectively). It was also observed that transplanted crop matured 10-12 days earlier than direct seeded maize.
