Authors:   Oromia Agricultural Research Institute, Mechara Agricultural Research Center, Mechara, Ethiopia, L Urgesa
Published: April 2023

Ethiopia has considerable livestock resource and poultry population is second ranked preceded by Cattle. Besides their important and numbers, little is known about their production systems, population growth, egg utilization trends and development strategies in Ethiopia. The Ethiopian poultry population is almost entirely composed of indigenous chicken and recent estimates showed that poultry 81.7%, 10.9%, and 7.4% are indigenous, hybrids and exotic, respectively. The distribution of poultry population in Ethiopia is diverging from region to region. Oromia region has the largest number of poultry population followed by Amhara, South Nation and Nationality People of Ethiopia (SNNP). Poultry production system in Ethiopia is indigenous and an integral part of farming system. Based on the objective, breed, flock size, housing, feeding, health, biosecurity level and technology used, the poultry production system in Ethiopia can be classified into extensive or scavenging, semi-intensive, small-scale intensive and large scale commercial poultry production system. The extensive scavenging and small-extensive scavenging systems are the dominant forms of poultry production in Ethiopia. The poultry population growth over the year almost stagnant because of high poultry mortality due to lack of adaptation of introduced exotic poultry, diseases, predators prevalent in the scavenging production systems and limited expansion of commercial poultry production both in terms of number of operators and volume of operation. The poultry sector did not have a clear roadmap guiding its development until the recent production of the LMP. The future study should be attention onto expansion of large scale commercial poultry production system, constraints of poultry population growth, adaption of introduced exotic poultry breeds and the reason for eggs sale and household consumption fluctuated.

Published: April 2023

Spinal Cord Injury (SCI) may result in the impairment of motor, sensory, and voluntary functions below the spinal level of injury. The global prevalence of SCI is 1:1000, with an incidence of 4–9 new cases per 100 000 people per year. The most common causes of traumatic SCI are traffic accidents, falls, and acts of violence. Currently, the prevalence of quadriplegia is comparable to that of paraplegia [1]. To the best of our knowledge, this case report highlights the use of spinal cord stimulation for the first time to treat traumatic complete paraplegia of the lower extremities, with substantial efficacy. We present the case of a 38-year-old Asian male, a truck driver by profession. He had suffered a complete loss of motor and sensory functions in both lower extremities in a traffic accident 3 years ago. The accident also resulted in an AIS-B injury (the sensory function is preserved in the S4-S5 area of the sacral segment, but no motor function is preserved) at the T11/T12 level, accompanied by alternating numbness, deep sensory disturbances, and dyskinesia in both lower extremities, with no spasticity in the legs, and a motor score of 0 for all key leg muscles (No muscle contraction). The patient did not show any clinical improvement in both lower extremities after spinal internal fixation and could not stand or walk (walking index score for SCI: 0), despite extensive rehabilitation in a rehabilitation center. Therefore, with the consent of the patient and his family, we exploratively implanted a Spinal Cord Stimulation (SCS) device in his body on April 26, 2020, to improve the symptoms of the lower extremities.

We surveyed Board Certified Behavior Analysts (BCBAs®) about their experiences with pediatric feeding problems. Results show that the most common forms of inappropriate mealtime behavior with which behavior analysts have worked are passive refusal, head turns, and elopement from the feeding area. The most common intervention techniques used by BCBA®s when working with feeding problems are shaping and graduated guidance. BCBAs® work most often with occupational therapists and speech-language pathologists when providing feeding-related services. We conclude by providing recommendations to equip behavior analysts to better manage feeding cases.

Published: April 2023

In modern conditions, the system of interaction between the university and representatives of the real sector of the economy is one of the key factors of competitiveness. In this regard, the development of a model of interaction “university - industrial enterprise” is especially relevant. The purpose of the study is to confirm the hypothesis that the graduate is the main source of partnerships for universities. The objectives of the study are: analysis of the current partnerships between the university and the graduate of the largest technical universities of the Russian Federation; determination of the levels of interaction between the university and representatives of the real sector of the economy (industrial enterprises); development of a “motivation ladder” for the graduate on the way to his transformation from an applicant who considers the university from the point of view of an assistant at the start of professional activity to a strategic partner - an industrial enterprise that considers the university as a source of research competencies; the development of an original model of interaction “university - industrial enterprise” based on the principles of crowdfunding and managing the grad[1]uate development cycle as a partner from the applicant to the employer . The authors developed a “motivational triad”, reflecting the predictive utility of cooperation in the long term. To confirm the practical significance of the conducted study, digital communication outlines were designed that describe key business processes and the achieved result at each level of interaction between the university and industrial enterprises, which can be integrated into the digital infrastructure of universities. The research described in this article was carried out using the methods of observation, collection, analysis and systematization of information.
Insights into the Mechanism and Regioselectivity of Palladium-Catalyzed Arylation of α,β-Unsaturated Ketones
Authors: Luo Jinbo , Su Xiaoxi , Chen Zhizheng , Qu Shuanglin
Published: April 2023

Transition-metal catalyzed coupling reactions of carbonyl compounds using simple chemical feedstocks have become a cornerstone of modern synthetic organic chemistry. The mechanisms and origins for ligand-controlled palladium-catalyzed regioselective α- and γ-arylation of α,β-unsaturated ketones with aryl halides have been investigated by density functional theory (DFT) calculations. Computational results have confirmed our proposed catalytic cycle, which includes four steps: oxidative addition, transmetallation, deprotonation/protonation, and reductive elimination. The Heck-type mechanism for α-arylation of α,β-unsaturated ketones is proved to be less feasible due to the high energy barrier for the insertion step. While reductive elimination is the rate-determining step (RDS), the critical process responsible for the regioselectivity depends upon the direction of protonation step, where the base function as a proton shuttle to facilitate H migration. Distortion/interaction analysis, natural bond orbital (NBO) analysis, and bur-ied volume calculations indicate that the regioselectivity is primarily controlled by the steric hindrance at the region of the ligand close to the enone. The indole ring of the phosphine ligand lay upward or downward, varying the space crowding in the region, thus leading to different protonation products followed by corresponding reductive elimination. The phenomenon of [1,5]-H trans-fer discovered in the γ-arylation of β-alkoxy cyclohexenones is also well rationalized by the proton shuttle model.

Published: April 2023

An enantioselective NiH-catalyzed syn-hydrocyclization of alkyne-tethered ketoamides for the synthesis of α-hydroxy γ-lactams is reported. Using Ni(OTs)2•6H2O/(S,S)-Me-Duphos as a precatalyst and (EtO)2MeSiH as a hydride source, a broad range of enantioenriched γ-lactams with a fully substituted stereogenic center are obtained in 32–84% yields with 89.5:10.5–96.5:3.5 er. Synthetic utilities, including scale-up reaction and product derivatization, are also demonstrated. This research represents a ligand-enabled regioselective functionalization of alkynes and provides an efficient strategy to access functional group-enriched chiral heterocycles.
Nature of the amorphous-amorphous interfaces in solid-state batteries revealed using machine-learned interatomic potentials
Authors: Wang Chuhong , Aykol Muratahan , Mueller Tim
Published: April 2023

Non-crystalline solid materials have attracted growing attention in energy storage for their desirable properties such as ionic conductivity, stability and processability. However, compared to bulk crystalline materials, fundamental understanding of these highly complex metastable systems is hindered by the scale limitations of density functional theory (DFT) calculations and resolution limitations of experimental methods. To fill the knowledge gap and guide the rational design of amorphous battery materials and interfaces, we present a molecular dynamics (MD) framework based on machine-learned interatomic potentials trained on the fly to study the amorphous solid electrolyte Li3PS4 and its protective coating, amorphous Li3B11O18. The use of machine-learned potentials allows us to simulate the materials at time and length scales that are not accessible to DFT while maintaining a near-DFT level of accuracy. This approach allows us to calculate amorphization energies, amorphous-amorphous interface energies, and the impact of the interface on lithium ion conductivity. This study demonstrates the promising role of actively-learned interatomic potentials in extending the application of ab-initio modeling to more complex and realistic systems such as amorphous materials and interfaces.

Published: April 2023

The knowledge of frontier orbital, highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), energies is vital for studying chemical and electrochemical stability of compounds, their corrosion inhibition potential, reactivity, etc. Density functional theory (DFT) calculations provide a direct route to estimate these energies, either in the gas-phase or condensed phase. However, the application of DFT methods becomes computationally intensive when hundreds of thousands of compounds are to be screened. Such is the case when all the isomers for the 1-alkyl-3-alkyllimidazolium cation [C$_n$C$_m$im]$^+$ (n = 1-10, m=1-10) are considered. Enumerating the isomer space of [C$_n$C$_m$im]$^+$ yields close to 316,000 cation structures. Calculating frontier orbital energies for each would be computationally very expensive and time-consuming using DFT. In this article, we develop a machine learning model based on extreme gradient boosting (XGBoost) method using the a small subset of the isomer space and predict the HOMO and LUMO. Using the model, the HOMO energies are predicted with a mean-absolute error (MAE) of 0.4 eV and the LUMO energies with MAE of 0.2 eV. Inferences are also drawn on type of the descriptors deemed important for the HOMO and LUMO energy estimates. Application of the machine learning model results in a drastic reduction in computational time required for such calculations.

Authors: Yuan Feng , Wong Wei
Published: April 2023

A new bioink consisted of single-walled carbon nanotubes (SWCNTs) conjugated with anti-HBsAg antibodies (SWCNT-Ab) was applied for the detection of HBsAg. The electrical conductivity of the printed film was optimized by printing multiple layers of the SWCNT-Ab bioink. The biosensors showed a linear response range from 1-10 mM HBsAg, and the response began to plateau after 10 mM, with a detection limit of 0.5 mM. The inkjet printed biosensors showed stable resistance and a linear response to increasing concentrations of HBsAg. The study suggests that this method has the potential for producing low-cost and sensitive biosensors for the early detection and accurate diagnosis of HBV in resource-limited settings.

The dynamic disulfide linkage plays a vital role in various biological processes as well as drugs and biomaterials. Oxidation of thiols is a widely utilized approach for disulfide synthesis; however, achieving both optimal reactivity and selectivity continues to pose a significant challenge. Here, we report the redox-click chemistry for disulfide formation from thiols by sulfonyl fluorides in both batch and flow-mode. Sulfuryl fluoride is a potent oxidant with exceptional selectivity toward thiols. This reaction's unique characteristics satisfy click chemistry's stringent criteria with its high thermodynamic driving force, simple reaction conditions, wide scope, quantitative yields, exceptional chemoselectivity, and non-chromatographic purification process. Furthermore, the redox click chemistry's ability to joining various modular thiol units was showcased in the synthesis of symmetrical, unsymmetrical and cyclic disulfides, poly(disulfide)s, and the in vivo disulfide cross-linked biomedical hydrogels.

Published: April 2023

Self-powered active micro/nanomotors have gained significant research attention in the scientific community due to their unique dynamics and emergent behaviors in response to various external stimuli. In recent years, different prototypes of micro/nanomotors have been investigated extensively for various fundamental studies and useful applications. Enzyme powered motors have emerged as ideal platforms for realizing various biological applications due to their multifunctionality and specificity in operation under complex conditions. However, most enzyme powered motors developed so far suffer from issues pertaining to their integration with biological systems due to retention of their synthetic components. With an aim to design a micromotor completely devoid of non-biological components, the present study reports the fabrication of a catalase driven, bovine serum albumin shelled microbubble motor. In substrate-rich environments, these ‘active’ microbubbles have been found to undergo substrate concentration dependent enhanced diffusion, just like their single enzyme counterparts. Brownian dynamics simulations have also been carried out to estimate the average force generated per catalytic turnover over the motor surface. Interestingly, it was found that these active microbubbles also possess the ability to transfer energy to their surroundings. The experiments were carried out within a three-dimensional setup that offered an advantage over the commonly used quasi two-dimensional systems, as it could enable researchers to probe micro/nanomotor dynamics and associated energy transfer profiles in more in vivo like settings.

This study delves into the current state and challenges of vocational education through a comparative study of cross-national vocational education and an analysis of the Zhaixing Academy case. The research reveals that vocational education reform can draw on the experiences of the German dual system, American community colleges, and Chinese vocational education reforms, with a focus on informal education pathways, practice-oriented teaching, and flexible training methods. The Zhaixing Academy case demonstrates the application of practice-oriented teaching approaches in the field of vocational education, emphasizing individual student development needs and the advantages of education outside formal institutions, offering new insights and references for the current Chinese education system. The study proposes that governments and education departments should increase investment in vocational education, encourage collaboration between enterprises and vocational education institutions, and support innovative practice-oriented education. In the future, Zhaixing Academy can continue to focus on education reform, expand the realm of practice-oriented education, promote its educational philosophy and methods, and contribute to the diversification and sustainable development of education.

Published: April 2023

Breast Cancer is a highly lethal reproductive cancer that disproportionately affects women and is a leading cause of death worldwide. Cancer is characterized by the uncontrolled division and invasion of abnormal cells into the surrounding tissues. Early detection is crucial in the diagnosis of Breast Cancer, as it accounts for a significant percentage of cancer diagnoses and deaths among women. To prevent unnecessary tests, accurate classification of malignant and benign tumors is necessary. Researchers have developed numerous automated classification methods for Breast Cancer, with soft computing techniques being widely used due to their high performance in classification. Machine learning algorithms, known for their ability to identify critical features from medical datasets, are also extensively utilized in Breast Cancer prediction. Therefore, this study seeks to employ Boosting algorithms in machine learning to predict Breast Cancer accurately. Over the years, the mortality rate in Breast Cancer diagnosis has decreased due to research efforts.

Objective. To improve the results of surgical treatment in patients with postoperative peritonitis, using the certain algorithm proposed.

Materials and methods. Prospective investigation was conducted on 244 patients, suffering postoperative peritonitis (the main group). In accordance to the peritoneal affection size the restricted postoperative peritonitis was present in 125 (51.2%) patients, and the extended one – in 119 (48.8%). Retrospective investigation consisted of studying of 212 cards of stationary patients, operated for postoperative peritonitis (the control group).

Results. Miniinvasive operative reinterventions were done in 114 (46.7%) patients, suffering postoperative peritonitis, of them in 55 (48.2%) laparoscopic sanation and drainage of the peritoneal cavity abscess was used. In 19 (55.9%) of 34 patients with postoperative peritonitis in the interloop abscesses a laparoscopic sanation and drainage of the abscess were performed. Open operative interventions were performed in 130 (53.3%) patients.

Conclusion. Application of the elaborated algorithm of the postoperative peritonitis surgical treatment have permitted to reduce the patients stationary stay from (14.2 ± 1.6) bed–days (control group) to (10.6 ± 1.2) bed–days (main group) and to reduce the lethality level from 31.6% (control group) to 18.4% (the main group).

Objective. To analyze the mistakes while application of modern surgical magnet instruments for diagnosis and removal of ferromagnetic foreign bodies.

Materials and methods. In accordance to the exploitation-clinical criteria, the material, delivered by usages of the magnet instruments (623 respondents), about results of its clinical usage in period from 2014 yr up to nowadays, was analyzed.

Results. In total the mistakes while application of surgical magnet instruments may be divided on two groups: the clinical and exploitation-technical  Most quantity of clinical mistakes are connected with application of such instruments without indications, basically in absence of ferromagnetic fractures inside the wounds channels and cavities. Other causes of the mistakes were following: failure to include physiologic peculiarities of the wound process course, such as formation of capsule over foreign bodies, characteristic of the wound channel, choice of inappropriate nomenclature specimen and failure to include the vessels and neural trunks projections, leading to development of complications (hemorrhage, neuralgia, paresis), formation of  the contraperture incision and mechanical removal of the fracture. Sterilization in a dry-heat wardrobe and physical damage of instruments were taken into account and have been considered as an exploitation-technical mistake.

Conclusion. In accordance to the results obtained, the conduction of educational trainings for usage of surgical magnet instruments, guaranteeing reduction of the various mistakes and complications quantity, leading to maximal effect of its application are recommended.

Published: April 2023

As the type and category of social problems expanded, it became complicated that could not be solved only by the state or market mechanism, and a social economy that combines social values and market economy emerged as a new alternative. The government recognizes the usefulness of social enterprises as a voluntary subject of social value creation and provides support policies for them, but the implementation level of support policies for social enterprises varies considerably from local governments. Therefore, in order to promote the implementation of social enterprise support policies, it is necessary to diagnose what factors cause differences across jurisdictions. The political and socioeconomic environment and conditions have been considered important as factors affecting the activism at the local government level. In this study, citizenship held by members of the local community is presented as one of the main environmental variables that affect the implementation of social enterprise support policies. As a result of analyzing local governments' social enterprise product purchases and citizen awareness survey data, it was confirmed that the solidarity factor of active citizenship had a positive effect on the execution of social enterprise support policies. Therefore, in order to develop the social economy, including social enterprises, policy efforts to promote citizens' social efficacy should be expanded.
