Published: April 2021

A study was conducted to evaluate the effect of management, breed, and their interaction on growth performance, egg production, and survivability under on-station and on-farm management conditions in Tanzania. A total of 1200 chicks, 600 for each breed, Kuroiler, and Sasso of mixed sexes were used. Birds under on-station management were confined and fed commercial ration throughout the experiment while those under on-farm management were allowed to semi-scavenge and supplemented with available feeds in the household. Brooding was carried out on-station for six weeks. Thereafter, birds were sub-divided for on-station and on-farm evaluation where data on body weight, egg production traits, and survival rate were taken at different ages from week 6 up to 52. The General Linear Models procedure fitting management, breed, and interaction between management and breed was used to analyze the data. Results show that management conditions had a significant influence on the performance of the breeds. Birds reared on-station performed better in all traits measured than those reared on-farm. The general effect of the breed was significant only for hen-day egg production (HDEP %) and hen-housed egg production (HHEP) in favour of Sasso chickens. Similarly, Sasso was more efficient at converting feed to live body weight. Interactions between management and breed were observed for all traits except peak egg production rate and mortality rate. While Sasso performance was better than that of Kuroiler on body weight, age at first egg, HDEP, age at peak egg production, and HHEP under the on-station management system, their performance in these traits were similar under the on-farm management except for body weight and age at first egg where Kuroiler was superior to Sasso. The survivability was also higher for Kuroiler than for Sasso under both management systems. It is concluded that genotype by environment (GxE) interaction had significant effects on the performance of the two breeds thus, a need to consider such effect when promoting them for either on-station or on-farm rearing.

Listening skills are important skills that need to be mastered by foreign language learners. Listening skills have, however, often been neglected in the teaching and learning process. This study aims to investigate the effectiveness of using WhatsApp messenger as an instructional tool in enhancing listening skills. This experimental research employs the two-group pre-test post-test design. Two groups of 30 students who enrolled in the Introductory Mandarin course in one of the public universities in Malaysia took part in the study. During the study, the experimental group of 30 students underwent listening drills and exercises using WhatsApp messenger as the treatment, while another 30 students in the control group were taught by another lecturer using the conventional method of teaching listening skills. Listening test scores of before and after the treatment were compared and analyzed using Independent Samples t-Test to identify the significant level of the difference between the scores of these two groups. The findings show no significant difference in the listening pre-test scores between both control and experimental groups. However, after the treatment, the listening scores of the experimental group students are significantly better than that of the control group students. These results indicate that WhatsApp messenger is a useful instructional tool to teach listening skills in foreign language. The findings of this study could be used as a reference for further development of WhatsApp messenger as an instructional tool to enhance listening skills, overcome the constraints on teaching time, and improve the pedagogy as well as the instructions of foreign language learning.

Linguistic landscape is a study field covering all linguistic objects in public spaces. It provides an important perspective for investigating the dynamics of social life and language change in given territories. Guangzhou, a significant commercial center in southern China, is renowned for its globalized development. With the growth of globalization, the increasing intrusion of English and the emerging English varieties have occurred in the urban linguistic landscapes of Guangzhou City. Therefore, this descriptive qualitative study collected English usage in the public sphere by taking pictures of private signs in two commercial centers. Monolingual and bilingual public signage displayed in public spaces shows that English has been an important foreign language widely used in Guangzhou's cityscape. Meanwhile, the use of English in Guangzhou is somewhat affected by local languages, a phenomenon called glocalization. The misuse of English, code-mixing between Chinese and English, and emerging English varieties are the product of glocalization. This study can shed light on the present linguistic situation of English in Guangzhou. Additionally, it provides evidence for the development process of glocalized English and translanguaging practice in southern Chinese communities.

Published: April 2021

The choice of clothing for enforcement personnel is vital to ensure minimum physical interference and optimum freedom of movement. The clothing type and fibre composition are important factors that have strong influence on the activities of enforcement personnel. This study presents an evaluation of the thermoregulatory responses for two type of enforcement personnel clothing after uphill running with different material composition.  Eight recreational trained respondents (age, 24.4 ± 2.3; height, 166.9 ± 3.3; body weight, 64.0 ± 5.8; BMI 23.0 ± 1.8) completed an 8 km run on a treadmill with 6% elevation wearing enforcement personnel clothing. Both clothing used in the trials were made of polyester/cotton (P50C50) and nylon/cotton (N20C80) material composition. The finding revealed that compared to P50C50 clothing, the N20C80 clothing does not have a good thermal balance. The loss of body mass did not vary significantly but the sweating rate differed significantly between trials (P = 0.008). The Rating of Perceived Exertion (RPE) of the participants was rated higher for N20C80 as compared to P50C50. The thermal sensation (P < 0.001), sweating sensation (P = 0.05), skin wetness (P = 0.007), clothing comfort (P < 0.01) and clothing humidity (P = 0.001) were significantly greater with N20C80 compared to P50C50 during exercise. The P50C50 clothing was more convenient to wear for the uphill running during the exercise. This study suggested that P50C50 would provide a better thermoregulatory response to regulate the thermal equilibrium between human skin and the environment.

Published: April 2021

In this study, this SiO2 has been coated on the surface of Fe3O4 (Fe3O4@SiO2) by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) under alkaline medium at 80oC. It was found that only 500  mL TEOS is required to obtain the best coated Fe3O4 core structures which has been confirmed from its TEM micrograph. FTIR analyses revealed the formation of Si-O-Si bonds at 1084.2–1101.4 cm-1 hence confirmed that SiO2 has been successfully coated the Fe3O4 core. From the FESEM analyses, the average size of silica was ~ 50 -70 nm.  EDX of the Fe3O4@SiO2 showed that silica had been effectively bonded onto the surface of Fe3O4. The VSM measurements confirmed the superparamagnetic properties of Fe3O4@SiO2 that is desirable for biomedical applications.
Hegel’s Account of Christianity and Religious Alienation
Authors: Stewart Jon
Published: April 2021

In his Lectures on the Philosophy of Religion, Hegel argues that the development of the religions of the world leads up to and culminates in Christianity, which is the one true religion. One key element which separates Christianity from the other religions, according to Hegel, concerns the issue of alienation. He argues that the previous religions all contain some form of alienation, which can be found in their conceptions of the divine. In this paper, I wish to examine Hegel’s view that Christianity alone overcomes religious alienation. What is it that makes Christianity so special in this regard? This is a particularly important issue given that the question of alienation is so central in the post-Hegelian thinkers such as Feuerbach, Bauer, and Marx, who all insist that, far from overcoming alienation, Christianity is guilty of causing it. I wish to argue that this issue provides new insight into the old criticism of Hegel as a thinker of abstraction.

Brayton-Moser Passivity Based Controller for Electric Vehicle Battery Charger
Authors:   Sardar Vallabhbhai National Institute of Technology, Shipra Kumari
Published: April 2021

In this paper Brayton-Moser passivity-based control (BM-PBC) methodology is developed for an on-board battery charger for plug-in electric vehicles(PHEVs). The main features of this electric vehicle (EV) charger include improved power quality, reduced filter size and voltage stress across the switches and fast dynamic response. In this paper, a dynamic model of the three-level (TL) boost power factor correction (PFC) converter is developed using the Brayton-Moser formulation. Then, the Brayton-Moser based control technique is designed by injecting a virtual resistor in series with the input inductor. Further, the stability analysis of the proposed controller is also carried out using energy balance approach. To improve the dynamic performance and reduce the steady state error, a PI controller is integrated with the aforesaid controller. Therefore, the controller comprises of BM-PBC and the PI controller is implemented for the TL boost PFC converter as a battery charger and its performances are investigated under various operating modes with the help of MATLAB/Simulink. Furthermore, power quality of charger is assessed by monitoring source current total harmonic distortion (THD) under different operating conditions. It is also observed that the proposed system provides THD less than 5% in source current which satisfies IEC 61000-3-2 Class C standard. The performance of the aforesaid controller is also compared with the conventional PI controller. In order to validate the proposed controller, a prototype model of same specifications is tested in hardware in loop and obtained test results are also presented.
Input/Output EMI Filter Design for Three-Phase Ultra-High Speed Motor Drive GaN Inverter Stage
Authors:   ETH Zurich, Antivachis Michael
Published: April 2021

Pairing wide-bandgap (WBG) inverters with high-speed motors results in compact and effi cient motor drives, but requires special attention on electromagnetic interference (EMI) aspects. This paper focuses on electromagnetic compatibility (EMC) of high-speed motor drives, supplied by a DC source. In order to protect the nearby equipment from the EMI noise of the WBG inverter, a fi lter that complies with conducted EMI regulations is placed at the inverter DC input-side. However, there is no clear mandate requiring from inverters to comply with conducted EMI regulations at the AC output-side, where only the motor is placed. For this reason, there is no full consensus whether it is necessary to use an output fi lter, and if so, what type of output fi lter would be suitable, i.e., if differential-mode (DM), common-mode (CM) or both DM/CM output fi lter would fi t best. A full sine-wave output fi lter (FSF) is proposed in this paper, that features both DM and CM attenuation, and capacitors connected to the DC link. Besides the several well established benefi ts of a FSF, such as purely sinusoidal motor currents and the protection of the motor against high du/dt originating from the fast switching of the semiconductor devices, a FSF at the inverter output-side, also reduces the CM EMI emissions at the inverter input-side. Namely, since the inverter housing, the motor housing and the interconnecting shielded cable are all grounded, CM emissions generated at the inverter output-side are directly mapped to the inverter input-side, i.e., there is an input-to-output CM noise interrelation. A FSF reduces the output-side CM EMI emissions and thus mitigates the input-to-output CM noise mutual influence. Two types of FSF (c-FSF and d-FSF) are comparatively evaluated, in terms of volume, losses and EMI performance. The theoretical consideration are tested within the context of a high-speed 280 krpm, 1 kW motor drive, with 80 V DC supply. The experimental results validate the good performance of the proposed filter concept.

Published: April 2021

Vegetables form major part of human dietary/nutritional needs. It provides the necessary vitamins and minerals as well as antioxidants to boost immunity. Different vegetables however have different benefits and require different growing conditions. This study investigated the effect of two growing conditions (Screen-house and open field) and soil amendments; Mexican sunflower compost (MSC; applied at 0, 5, 10 t/ha) and NPK 15:15:15 (applied at 0, 50 and 100 kg N/ha) on the growth performance, yield, and nutritional quality of five selected vegetables (Amaranthus cruentus, Celosia. argentea, Solanum macrocarpon, Solanum nigrum and Solanum incanum). Each treatment was replicated three times and experiment arranged in completely randomized design, Compost was applied a week before seed sowing vegetables grown in the screen-house generally performed better than the open field in terms of leaf area and chlorophyll content. The response however varied based on the vegetable and the soil amendments. Solanum species, performed better than Amaranthus under screen-house than open field. Chlorophyll in the leaf responded positively to NPK fertilizer under screen-house conditions while growth parameters such as plant height, stem girth, number of leaves under screen-house and field conditions varied depending on the vegetables. The number of leaves and leaf area increased with soil amendments. Moisture, crude protein and ash contents were reduced under open field compared to screen-house. The zinc and iron contents of the vegetable leaves showed that addition of compost was superior to NPK and screen-house better than open field. It can be concluded that vegetables grown in the screen-house performed better in their respective growth parameters than vegetables are grown under the open field.

Authors: Zadro Joshua R. , O'Keeffe Mary , Ferreira Giovanni E. , Haas Romi , Harris Ian A. , Buchbinder Rachelle , Maher Christopher G.
Published: April 2021

Objective

To investigate whether different labels for rotator cuff disease influence people's perceived need for surgery.

Design

Randomized controlled experiment.

Methods

Participants with and without shoulder pain read a vignette describing a patient with rotator cuff disease and were randomized to 1 of 6 terms describing rotator cuff disease: subacromial impingement syndrome, rotator cuff tear, bursitis, rotator cuff–related shoulder pain, shoulder sprain, and episode of shoulder pain. Perceived need for shoulder surgery was the primary outcome. Secondary outcomes included perceived need for imaging, an injection, a second opinion, and to see a specialist; perceived seriousness of the condition; recovery expectations; and perceived impact on work attendance. Using a Bonferroni correction (significance, P<.003), adjusted between-group mean differences and 99.67% confidence intervals (CIs) were obtained using a 1-way analysis of covariance.

Results

One thousand three hundred eight (80% of 1626) responses were analyzed. Participants' mean ± SD age was 40.3 ± 16.0 years, and 59% were women. Mean perceived need for surgery (0–10 scale) was low and slightly higher among those assigned to the rotator cuff tear label compared to the bursitis label (2.6 versus 2.1; adjusted mean difference, 0.7; 99.67% CI: 0.0, 1.4). Mean perceived need for imaging (0–10) was moderate and slightly higher among those assigned to the rotator cuff tear (4.7 versus 3.7; adjusted mean difference, 1.0; 99.67% CI: 0.2, 1.9) and subacromial impingement syndrome labels (4.7 versus 3.7; adjusted mean difference, 1.0; 99.7% CI: 0.1, 1.9) compared to the bursitis label.

Conclusion

There were small differences in the perceived need for surgery and imaging between some labels, which could be important at the population level. J Orthop Sports Phys Ther 2021;51(8):401–411. Epub 31 Mar 2021. doi:10.2519/jospt.2021.10375
No Added Benefit of 8 Weeks of Shoulder External Rotation Strength Training for Youth Handball Players Over Usual Handball Training Alone: A Randomized Controlled Trial
Authors: Fredriksen Hilde , Cools Ann , Myklebust Grethe
Published: April 2021

Objective

To assess the effectiveness of a short (5–10 minutes) shoulder external rotation (ER) strength program, using elastic bands, in adolescent handball players.

Design

Randomized controlled trial.

Methods

The sample included 6 adolescent handball teams (3 female, 3 male) with a total of 92 players and a mean age of 16.6 years. Players were randomized within teams to an intervention group, which completed a shoulder ER strengthening program of 2 exercises performed 3 times per week after handball training for 8 weeks, or a control group of no treatment. The primary outcome was the between-group difference in shoulder ER strength change, measured as isometric strength using a handheld dynamometer from preintervention to postintervention (8 weeks). Secondary outcomes were between-group differences in internal rotation (IR) strength and the ER/IR strength ratio from preintervention to postintervention.

Results

The estimated between-group difference in dominant-shoulder ER strength was 0.06 N/kg (95% confidence interval [CI]: −0.01, 0.14) in favor of the intervention group. The estimated between-group differences in the ER/IR ratio and IR strength were 0.03 (95% CI: −0.02, 0.08) and 0.02 (95% CI: −0.08, 0.13), respectively.

Conclusion

The ER strength program improved neither the ER strength nor the ER:IR ratio. J Orthop Sports Phys Ther 2021;51(4):174–187. doi:10.2519/jospt.2021.9957

Authors: Panggabean Siska Naomi
Published: April 2021

The emergence of e-Court as a modernization on trials enabled the judicial process to run online. The application allowed users, including Persons with Disabilities (PwD). Since the online system is essentially similar to the on-site one, the judicial process should consider reasonable accommodation. Moreover, considering Government Regulation Number 39 of 2020 concerning Reasonable Accommodations for Person with Disabilities (Regulation of Reasonable Accommodation in Judicial Process), the types of accommodations to enable PwD to use the online system must be clear. How the reasonable accommodations provided in e-Court is the issue of this research. The method of research used to elaborate on this issue is the normative juridical method. Patterns of problem approach are statute approach and conceptual approach. Meanwhile, the Analytical Descriptive method is used to construct the data. In this writing, automated online web accessibility tests showed that the medium percentage of the e-Court's accessibility is used to bolder the analysis. This writing elaborated the accessibility of e-Court and the components of the information within which needed to be enhanced for providing reasonable accommodation for Persons with Disabilities, mainly in the form of service. It also touched on the Standard of Judicial Process involving Persons with Disabilities and the provision of the Companion and/ or the Translator for Persons with Disabilities during the trial process linked with the personal assessment and the participation of society.

De novo, in-silico design of molecules is a challenging problem with applications in drug discovery and material design. We introduce a masked graph model, which learns a distribution over graphs by capturing conditional distributions over unobserved nodes (atoms) and edges (bonds) given observed ones. We train and then sample from our model by iteratively masking and replacing different parts of initialized graphs.

We evaluate our approach on the QM9 and ChEMBL datasets using the GuacaMol distribution-learning benchmark. We find that validity, KL-divergence and Fréchet ChemNet Distance scores are anti-correlated with novelty, and that we can trade off between these metrics more effectively than existing models. On distributional metrics, our model outperforms previously proposed graph-based approaches and is competitive with SMILES-based approaches. Finally, we show our model generates molecules with desired values of specified properties while maintaining physiochemical similarity to the

training distribution.

Published: April 2021

A gram-scale synthesis of iboxamycin, an antibiotic candidate bearing a fused bicyclic amino acid residue, is presented. A pivotal transformation in the route involves an intramolecular hydrosilylation–oxidation sequence to set the ring-fusion stereocenters of the bicyclic scaffold. Other notable features of the synthesis include a high-yielding, highly diastereoselective alkylation of a pseudoephenamine amide, a convergent sp3–sp2 Negishi coupling, and a one-pot transacetalization–reduction reaction to form the target compound’s oxepane ring. Implementation of this synthetic strategy has provided ample quantities of iboxamycin to allow for its in vivo profiling in murine models of infection.

Published: April 2021

The biomedical and surgical applications of hydrogels demand effective methods to adhere hydrogels to diverse substrates including living tissues. Here we present a mussel mimetic polyurethane as topological suture material for tough adhesion of hydrogels by introducing catechol moieties into polymer chains. Solution of the stitching polyurethane can be injected onto the surface of a hydrogel, followed by diffusing spontaneously into the hydrogel, then get triggered by oxidant for in situ gelation. Oxidative cross-linkage of catechol-modified polyurethane after penetration into hydrogels or living tissues could establish enough covalently entangled networks to afford desired adhesion strength. The mussel mimetic polyurethane demonstrates excellent adhesion strength of hydrogels to universal substrates including inorganics, polymers, and biomaterials, with no requirements for specific functional groups or chemical modification. The adhesion energy achieved by the topological stitching strategy can reach up to 350 J/m2. Moreover, the stitching polymer shows good biocompatibility and the potential for debonding under the catalysis of elastase. This work will possibly become a promising strategy candidate for adhesion in wet environments.

We use second harmonic generation spectroscopy, molecular dynamics simulation, and theoretical modeling to study the response of the neat liquid water-air interface to changes in the potential of an external electrode positioned above the liquid. We observe a parabolic dependence of second harmonic intensity on applied potential, indicating that water’s net interfacial dipole responds linearly. We also observe a minimum intensity when the potential is tuned to a specific positive value. Interpreting this minimum based on the macroscopic electrostatic potential profile yields misleading physical conclusions because it neglects the internal bias exerted on molecular orientations by the excess surface concentrations of OH- or H3O+. We thus find that water’s net interfacial dipole orientation is primarily responsive to the effects of these ionic species rather than the external electric field.
Rh(III)-Catalyzed Three-Component Syn-Carboamination of Alkenes Using Arylboronic Acids and Dioxazolones
Authors: Lee Sumin , Rovis Tomislav
Published: April 2021

Herein we report a Rh(III)-catalyzed three-component carboamination of alkenes from readily available aryl boronic acids as a carbon source and dioxazolones as nitrogen electrophiles. This protocol provides facile access to valuable amine products including a-amino acid derivatives in good yield and excellent regioselectivity without the need for a directing functionality. A series of experiments suggest a mechanism in which the Rh(III) catalyst undergoes transmetalation with the aryl boronic acid followed by turnover limiting, alkene migratory insertion into the Rh(III)-aryl bond. Subsequently, fast Rh-nitrene formation provides the syn-carboamination product selectively after reductive elimination and proto-demetalation. Importantly, the protocol provides 3-component coupling products in preference to a variety of 2-component undesired by-products.
Magnetoelectric Coupling on the Fused Azulene Oligomers

Published: April 2021

The global magnetic phase diagram for fused azulene oligomers is obtained by using a fermionic Hubbard Hamiltonian, a intermediate model between the molecular (Pariser-Parr-Pople empiric Hamiltonian) and spin-1/2 antiferromagnetic Heisenberg approaches. As a function of the on-site coulomb repulsion and the oligomer size we show that fused azulene transitions from a singlet (S = 0) to a higher-spin (S = 1, 2, 3) ground state. Near the quantum magnetic phase transition the electric dipole moment, present on fused azulene molecules, couples with the magnetic moment leading to a divergent magnetoelectric susceptibility at the boundary lines of the magnetic phase diagram. These spontaneous electric and magnetic polarizations, together with the magnetoelectric coupling between them, indicate that fuzed azulene molecules are potentially strong candidates for purely organic multiferroic materials.

Published: April 2021

Nasal polyps are macroscopic oedematous lesions in the nose openings are the most common problem of the patients. Main causes of the polyps are due to inflammatory conditions and allergy. An association with asthma, aspirin sensitivity and cystic fibrosis was seen in the population. The main objectives of medical treatment of nasal polyps are to eliminate or reduce the size of the polyps thereby improving the symptoms of rhinitis and breathing. The clinical characteristics and treatment pattern among the 125 patients having nasal polyps was analyzed by a retrospective, observational study using patient’s medical records and hospital data management system. Males predominated in the present study (64.8%) and majority of the patients were in the age group of 41-60 years (44%). Most of the patients suffered from sinonasal polyposis (76.8%) with the main symptom being nasal block (88.8%). Most of the polyps were of the inflammatory origin (53.6%). Asthma and rhinitis were observed in 11% patients. Majority of the patients were treated with corticosteroids and antihistamines. Many patients required surgery for the management of nasal polyps. Nasal polyps appear to be associated with inflammatory and may be an allergic response. Most of the patients require surgery while few can be managed with anti-inflammatory and/or anti-allergic drugs.

Published: April 2021

Biogenic amines generally can be found in fish due to amines in fish undergoing a degradation process. According to the United States Food and Drug Administration (FDA), biogenic amines in fish and fish products can cause harm to consumers if consumed more than 50 µg/mL. Thus, it is important to analyze them. Five biogenic amines such as heptylamine, histamine, tyramine, cadaverine and spermidine were extracted using soaking method with methanol 50% (v/v), afterward they were detected in fish and fish products using gas chromatography – flame ionisation detector (GC-FID) and the biogenic amines structures were confirmed using mass spectrometry (MS). The detection limits (DLs) were range at 1.20 – 2.90 µg/mL. Histamine was detected in fish and fish products such as sardine (Sardinella gibosa) and mackerel (Scomberomorus guttatus) at concentration of 5.96 and 2.69 µg/mL, respectively, whereas cadaverine was found in sardine (Sardinella gibosa) at concentration of 4.96 µg/mL. Histamine concentrations in this study were detected below 50 µg/mL which is below the permissible threshold associated with scombroid poisoing.

A cross-domain sentiment analysis (CDSA) study in the Indonesian language and tree-based ensemble machine learning is quite interesting. CDSA is useful to support the labeling process of cross-domain sentiment and reduce any dependence on the experts; however, the mechanism in the opinion unstructured by stop word, language expressions, and Indonesian slang words is unidentified yet. This study aimed to obtain the best model of CDSA for the opinion in Indonesia language that commonly is full of stop words and slang words in the Indonesian dialect. This study was purposely to observe the benefits of the stop words cleaning and slang words conversion in CDSA in the Indonesian language form. It was also to find out which machine learning method is suitable for this model. This study started by crawling five datasets of the comments on YouTube from 5 different domains. The dataset was copied into two groups: the dataset group without any process of stop word cleaning and slang word conversion and the dataset group to stop word cleaning and slang word conversion. CDSA model was built for each dataset group and then tested using two types of tree-based ensemble machine learning, i.e., Random Forest (RF) and Extra Tree (ET) classifier, and tested using three types of non-ensemble machine learning, including Naïve Bayes (NB), SVM, and Decision Tree (DT) as the comparison. Then, It can be suggested that the accuracy of CDSA in Indonesia Language increased if it still removed the stop words and converted the slang words. The best classifier model was built using tree-based ensemble machine learning, particularly ET, as in this study, the ET model could achieve the highest accuracy by 91.19%. This model is expected to be the CDSA technique alternative in the Indonesian language.
