Maturation rate of sheep oocytes cultured in suboptimal environment using CO2 exhaled by human and glutathione addition

This study aimed to identify the effect of the use of CO2 exhaled by human (CEbH) in in vitro maturation (IVM) with the addition of Glutathione also known as GSH on the oocytes maturation rate. It is known that CO2 derived from human respiration can be used as alternative support for IVM of oo-cytes. However, this method is categorized as using a suboptimal culture environment, and it results in increased production of reactive oxidative species (ROS). Thus, the addition of the antioxidant GSH is needed. In total, 273 oocytes were cultured in three groups: 5% CO2 (control) and CEbH with 0 mM and 1 mM of GSH addition, respectively. The results showed that the control group produced a better maturation rate (p < 0.05) compared to the remaining two groups (65.92% vs. 24.44% and 30.61%), which used CEbH. Statistically, 0 mM GSH vs. 1 mM GSH did not show any significant differences (p > 0.05). However, 1 mM GSH led to more mature oocytes (24.44% vs 30.61%) compared to the group without GSH. In conclusion, IVM using CEbH supports oocyte maturation, and the addition of GSH can improve the maturation rate in a suboptimal culture environment.
SSR-Based Genetic Structure Study of Seventy-Eight Cowpea (Vigna unguiculata (L.) Walp) Genotypes

Seventy-eight cowpea accessions were studied using short sequence repeats (SSR) technique. Genetic structure of these accessions was studied using three SSR polymorphic primers, SSR-6206, SSR-6218 and SSR-6219. A total of eight loci were scored for the three primers with a total of ten alleles. Bayesian clustering method grouped the cowpea genotypes into 4 sub-populations. Ancestral allele frequencies ranged between 0.128 and 0.802, while allele frequencies within sub-populations ranged from 0.001 and 0.997. Allele frequency divergence among sub-populations ranged from 0.145 to 0.406. Expected heterozygosity between individuals in the same sub-population ranged from 0.084 and 0.26, Mean genetic differentiation among sub-populations ranged from 0.374 and 0.687, with a mean geneflow ranging from 0.228 and 0.837. There was relative uniformity within the sub-populations which can be accounted for by independent random genetic drift.
A new metastable phase with T/sub c/ of 32 K in La/sub 2/CuO/sub 4+/spl delta// system

A metastable superconducting phase with T/sub c/ of 32 K and /spl delta/=0.084 in La/sub 2/CuO/sub 4+/spl delta// system is reported in this paper. It is prepared by electrochemical oxidation for more than 2 months using a small constant current of 10 /spl mu/A. Its structure and physical properties are studied by X-ray diffraction, magnetic susceptibility and resistance measurements. This phase (we call it /spl beta/-phase) is different from the previously known one (we call it /spl alpha/-phase) that has the same T/sub c/ but 0/spl les//spl delta//spl les/0.055. After heat treatment at temperature T=80/spl deg/C, the /spl beta/-phase decomposes into two phases with T/sub c/'s of /spl sim/17 K and /spl sim/30 K, respectively. This kind of behavior is similar to the phase with T/sub c/ of 45 K. Our study shows that T/sub c/ increases with the intercalation rate, and oxygen distribution is an important factor for controlling superconducting properties.
Prediction of surface roughness of CO2 laser modified poplar wood via response surface methodology

Due to the advantages of short treatment period, no wastewater and oil produced, the CO 2 laser is applied as an environment friendly thermal treatment for wood materials to improve the wood properties, such as ap-pearance, color and wettability, among others. However, the morphological features of treated wood surface are also changed, which have negative effects on wooden product properties. To reveal the change tendency of surface roughness during laser irradiation, the common indexes of average roughness (Ra) and mean peak-to-valley height (Rz) were chosen to evaluate the surface roughness. The response surface methodology was selected to arrange the experiments and analyze the influences of laser parameters on surface roughness. The results showed that the poplar wood got rougher with the increased laser power, but the surface roughness decreased with increased feed speed and path spacing, due to the total heat absorption varied under different com bination of laser parameters. The ANOVA results showed that the selected quadratic models for Ra , Rz , Ra and Rz were significant due to the values of probability value (“Prob>F”) less than 0,05. In this case, all the input laser parameters were also the significant model terms for variation of surface roughness. The values of correlation coefficient were very close to 1, which meant the selected quadratic models could give accurate prediction of surface roughness for laser treated wood. Therefore, it is of great significance to predict the surface roughness of the modified wood surface scientifically and to guide the selection of reasonable modifi cation process parameters.
Trapping fermionic and bosonic helium atoms

This thesis presents experimental and theoretical work performed at the Laser Centre of the Vrije Universiteit in Amsterdam to study laser-cooled metastable triplet helium atoms. Samples containing about 3x10^8 helium atoms-either fermionic helium-3 atoms, bosonic helium-4 atoms or mixtures thereof-are cooled to a temperature around 1 mK and form the starting point of the presented studies. The studies include an investigation of cold ionizing collisions in the absence of resonant light, an investigation of magneto-optical trapping with ultraviolet light, a feasibility study of an atomic fountain clock based on metastable helium-3 atoms and the first demonstration of magneto-optical trapping of an isotopic mixture of metastable helium atoms.
Illness Perceptions and Self-Management among People with Chronic Lung Disease and Healthcare Professionals: A Mixed-Method Study Identifying the Local Context

Self-management interventions (SMIs) may fail if they misalign with the local context. To optimize the implementation of SMIs in Chinese people with chronic lung disease (CLD), the local context was identified in Chinese primary care (PC) and secondary care (SC). A mixed-method study using semi-structured interviews and quantitative surveys was conducted on people with CLD and healthcare professionals (HCPs). The qualitative data was collected until data saturation was reached, and participants were invited to complete the survey after the interview. The qualitative data—analyzed with the framework approach—was triangulated with the quantitative data. A total of 52 participants completed the interviews, and 48 also finished the survey. Four themes were identified; (a) illness perceptions (e.g., patients had poor CLD knowledge and SM, inadequate resources lead to suboptimal disease control in PC); (b) self-management skills (e.g., most patients delayed exacerbation recognition and action, and some were admitted at the crisis point); (c) factors influencing self-management skills (e.g., (in)adequate disease knowledge and medical expenditure affordability); and (d) needs for self-management (e.g., increased disease knowledge, individualized self-management plan, eHealth, (healthcare insurance) policy support). Identified themes were dependent on each other and should be leveraged when implementing SMIs. Ultimately, such SMIs can optimize patient health outcomes.
New construction for a QMA complete three-local Hamiltonian

We present a new way of encoding a quantum computation into a three-local Hamiltonian. Our construction is novel in that it does not include any terms that induce legal-illegal clock transitions. Therefore, the weights of the terms in the Hamiltonian do not scale with the size of the problem as in previous constructions. This improves the construction by Kempe and Regev [Quantum Inf. Comput. 3, 258–264 (2003); e-print quant-ph∕0302079] who were the first to prove that three-local Hamiltonian is complete for the complexity class QMA, the quantum analog of NP. Quantum k-SAT, a restricted version of the local Hamiltonian problem using only projector terms, was introduced by Bravyi (e-print quant-ph∕0602108) as an analog of the classical k-SAT problem. Bravyi proved that quantum 4-SAT is complete for the class QMA with one-sided error (QMA1) and that quantum 2-SAT is in P. We give an encoding of a quantum circuit into a quantum 4-SAT Hamiltonian using only three-local terms. As an intermediate step to this th.
High-resolution transmission electron microscopy studies of planar defects in the magnetic superconductor RuSr2EuCu2O8

The defect structure in powders of the 1212-type phase RuSr2EuCu2O8 was investigated using high-resolution transmission electron microscopy. Both 90° domain boundaries and planar “faults” on {100} were observed. By comparing images of the faults with simulations for various plausible atomic models, it was shown that they are crystallographic shear planes with a displacement vector of R=(1∕6)⟨332⟩. Such defects correspond to a local deficiency in Ru, Cu, and O, and give a local discontinuity in the Ru-O charge reservoir planes. As such, these defects may be responsible for the sensitivity of the superconducting and magnetic properties to processing conditions.
Sick Leave in Colombia in the 2016–2018 period: A Retrospective Cross-Sectional Observational Study

Introduction: To understand the sick leave situation and the causes and effects of a temporary loss of capacity to work allows for the strengthening of policies and management in the provision of health services. Objective: To analyze sick leave in Colombia in the 2016–2018 period. Materials and methods: A retrospective cross-sectional observational study and the relative risk was calculated. Sick leave reports were provided by the Ministry of Health and Social Protection. 12,410,837 reports from formal workers between the ages of 18–70 years and had at least one temporary disability were processed. Results: The average age of people with sick leave was 37.11 years, 53% corresponding to females. On average, sick leave was 90.6% and 5.6% for dependent and independent workers, respectively. The principal causes of disability were musculoskeletal diseases and were more likely in men and adults according to RR. Men in comparison to females and adults in comparison to youths are less likely to have sick leave due to respiratory disease. Conclusions: In Colombia, females presented more temporary sick leave, even if males had more days of disability, even though the median was three days in both genders. Youth and adults had more sick leave days.
Resistance of the cattle tick Rhipicephalus microplus to alphacypermethrin, deltamethrin and amitraz in Côte d’Ivoire

Cattle tick Rhipicephalus microplus has become a common problem for cattle herders in Côte d’Ivoire after its discovery there in the early 2000s, despite the availability of a large range of acaricide products. The objective of this study was to assess the resistance of the cattle tick R. microplus to alphacypermethrin, deltamethrin and amitraz, and to provide information to advice farmers of acaricide products choice in Côte d’Ivoire. A cross-sectional survey was conducted in September 2016 on nine farms where resistance to acaricides was suspected. Engorged R. microplus females were sampled and transported to the International Centre for Research and Development on Subhumid Livestock Production (CIRDES) in Burkina Faso. The FAO larval packet test method (adapted by CIRDES) was applied to assess the resistance-susceptibility level of the R. microplus tick populations to three common acaricidal molecules (alphacypermethrin, deltamethrin and amitraz) in Côte d’Ivoire. The results showed resistance ratios (RR) at 50% (RR50 95% CI) ranging from 0.26 (0.20-0.33) to 1910.3 (0.0-9063.3). High resistance to amitraz and deltamethrin was found on all farms, whereas resistance of tick populations to alphacypermethrin varied by farm from very susceptible to highly resistant. These results indicate that alphacypermetrin should remain a recommended acaricide on some farms in the country and underline the importance of raising awareness on the appropriate use of acaricides and monitoring acaricide resistance in tick populations in Côte d’Ivoire. Such actions will support farmers in the control and prevention of R. microplus infestation in cattle herds in Côte d’Ivoire.
Efficacy and safety of esophagectomy via left thoracic approach versus via right thoracic approach for middle and lower thoracic esophageal cancer: a multicenter randomized clinical trial (NST1501)

Background Left thoracic approach (LTA) has been a favorable selection in surgical treatment for esophageal cancer (EC) patients in China before minimally invasive esophagectomy (MIE) is popular. This study aimed to demonstrate whether right thoracic approach (RTA) is superior to LTA in the surgical treatment of middle and lower thoracic esophageal squamous cell carcinoma (TESCC). Methods Superiority clinical trial design was used for this multicenter randomized controlled two-parallel group study. Between April 2015 and December 2018, cT1b-3N0-1M0 TESCC patients from 14 centers were recruited and randomized by a central stratified block randomization program into LTA or RTA groups. All enrolled patients were followed up every three months after surgery. The software SPSS 20.0 and R 3.6. 2. were used for statistical analysis. Efficacy and safety outcomes, 3-year overall survival (OS) and disease-free survival (DFS) were calculated and compared using the Kaplan-Meier method and the log-rank test. Results A total of 861 patients without suspected upper mediastinal lymph nodes (umLN) were finally enrolled in the study after 95 ineligible patients were excluded. 833 cases (98.7%) were successfully followed up until June 1, 2020. Esophagectomies were performed via LTA in 453 cases, and via RTA in 408 cases. Compared with the LTA group, the RTA group required longer operating time (274.48±78.92 vs. 205.34±51.47 min, P<0.001); had more complications (33.8% vs. 26.3% P=0.016); harvested more lymph nodes (LNs) (23.61±10.09 vs. 21.92±10.26, P=0.015); achieved a significantly improved OS in stage IIIa patients (67.8% vs. 51.8%, P=0.022). The 3-year OS and DFS were 68.7% and 64.3% in LTA arm versus 71.3% and 63.7% in RTA arm (P=0.20; P=0.96). Conclusions Esophagectomies via both LTA and RTA can achieve similar outcomes in middle or lower TESCC patients without suspected umLN. RTA is superior to LTA and recommended for the surgical treatment of more advanced stage TESCC due to more complete lymphadenectomy. Trial Registration ClinicalTrials.gov NCT02448979.
The action of a semisimple Lie group on its maximal compact subgroup

In this paper we determine the structure of the minimal ideal in the enveloping semigroup for the natural action of a connected semisimple Lie group on its maximal compact subgroup. In particular, if G = KAN is an Iwasawa decomposition of the group G, then the group in the minimal left ideal is isomorphic both algebraically and topologically with the normalizer M of AN in K. Complete descriptions are given for the enveloping semigroups in the cases G = SL(2, C) and G = SL(2, R).

Can pasture defoliation management targets be similar under full sun and shaded conditions?

Abstract Context. Defoliation management targets applied to forages under the full sun have not yet been properly evaluated for shaded environments such as occur in integrated crop–livestock systems with the presence of trees. AimsThis study aimed to determine defoliation targets under full sun and shaded environments for the shade-tolerant perennial summer grass hybrid Axonopus catharinensis (giant missionary grass), widely used in pasture systems of South Brazil and Argentina. Methods. Four pre-defoliation canopy heights (15, 25, 35 and 45 cm) and four defoliation severities (20%, 40%, 60% and 80% reduction in pre-defoliation canopy height) were evaluated. Plants were grown in 0.15 m3 wooden boxes filled with sand/vermiculite substrate (1:1 v/v) and irrigated with a complete nutrient solution. An artificial shade structure was made with wooden slats, reducing light intensity by 50% for shaded plants. Key results. Herbage accumulation decreased by 54% in shaded plants compared with those under full sun. Regardless of the light environment, the lowest crude protein content (<150 g/kg dry matter) and the highest neutral detergent fibre content (>650 g/kg dry matter) were observed when the defoliation target height was >35 cm. Both shaded and full sun environments showed decreases in tiller density when defoliation severity was >60% of pre-defoliation canopy heights. Conclusions. Pre-defoliation canopy heights >35 cm and defoliation severity >60% of pre-defoliation canopy height should be avoided when managing A. catharinensis, regardless of the light environment. Implications. Recommended targets may be easily implemented by livestock producers and are similar for full sun and shade environments.
Microgrid Stability Improvement Using a Deep Neural Network Controller Based VSG

In order to support the inertia of a microgrid, virtual synchronous generator control is a suitable control method. However, the use of the virtual synchronous generator control leads to unacceptable transient active power sharing, active power oscillations, and the inverter output power oscillation in the event of a disturbance. This study aims to propose a deep neural network controller which combines the features of a restricted Boltzmann machine and a multilayer neural network. To initialize a multilayer neural network in the unsupervised pretraining method, the restricted Boltzmann machine is applied as a very important part of the deep learning controller. The Lyapunov stability method is used to update the weight of the deep neural network controller. The proposed method performs power oscillation damping and frequency stabilization. The experimental and simulation results are presented to assess the usefulness of the suggested method in damping oscillations and frequency stabilization.
Influence of Adapted Physical Facilities on the Execution of Inclusive Education in Public Preschools in Belgut Sub-County, Kenya

Inclusive education is one of the key areas articulated in Sustainable Development Goal No.4. which global nations aspire to implement. Effective execution of Inclusive education requires institutions of learning to create disability-friendly environments whereby the physical facilities are structured to allow learners with special needs to participate on an equal basis in school activities with their typically growing peers. However, the execution of Inclusive education is yet to be accomplished globally. The objective of the study was to establish the influence of physical facilities on the execution of Inclusive education in the public preschools in Belgut Sub-County, Kenya. The study adopted the social model of disability theory. The study also utilised a descriptive survey research design. The target population of the study was 238 out of which a sample size of 168 participants comprising 113 preschool teachers and 65 primary school head teachers was selected. Sampling was done using stratified and simple random sampling techniques. Data for the study was collected using an observation checklist, pre-primary school teachers and the head teachers’ questionnaires. Data were analysed using descriptive statistics with the help of Statistical Package for Social Sciences (SPSS) Version 22 and presented in the form of frequencies and percentages displayed in distribution tables. The results showed that the majority of preschools had classrooms that were accessible to learners with disabilities. However, the results also revealed that the majority of them lacked rails on entrances to buildings, adapted toilets, ramps, swings, wide pavements, adapted desks/ furniture, and swings. The study concluded that adapted physical facilities influence the execution of Inclusive education in public preschools negatively. The study recommends that the County Government provides sufficient funds to preschools to aid in restructuring the existing physical facilities to attain disability friendly status.
Heterogeneity evaluation of pore types based on dipole shear sonic imager logs by means of statistical parameters, the central Persian Gulf

Heterogeneity analysis in carbonate reservoirs is of great importance for the interpretation of their characteristics. This study focuses on the evaluation of pore‐type heterogeneity by means of the sonic wave velocities in the carbonate–evaporite series of Permian–Triassic sequences in the Persian Gulf. Thin section petrography and laboratory measured the porosity and permeability of 1576 samples, as well as routine wire‐line logs, were employed. To manage heterogeneity, six electrofacies (EF) were determined based on an integrated analysis of compressional, shear and Stoneley waves as well as three routine logs (gamma, neutron and density). The frequency of pore types in each electrofacies was calculated. Then, the heterogeneity of pore‐type distribution in each electrofacies was measured by standard error and coefficient of variation. Sonic velocity has been compared with the geological properties of electrofacies. Results indicated that velocity is affected by factors other than the amount of porosity, facies or lithology. The standard error values in all electrofacies were close to zero. The coefficient of variation values ranges from 1.08 to 4.60. The lowest amount of coefficient of variation was observed in EF6 in the Khuff (K) 4 zone for moldic porosity. This value for intercrystalline porosity distribution in EF1 in the K1 zone was low, too. These results indicate the lowest standard deviation and the highest homogeneity in the distribution of intercrystalline and moldic porosities in K1 and K4. Also, comparing the mean values of sonic logs in each electrofacies with the total mean value in the whole sequence indicated that there is a relationship between sonic velocity logs and the type of porosity. High values of sonic velocity correspond to intercrystalline porosity in K1 and low values of velocity correspond to moldic porosity in K4. Results show that integrated pore‐type studies should be carried out to understand the sonic velocities in carbonate reservoir rocks.
