Organic waste that comes from daily food leftovers in the community has not been used properly, people still put together organic waste and non-organic waste which is then burned, this results in the environment being exposed to carbon dioxide from burning garbage. In Nyalindung Village, many of the people make a living as breeders and farmers, where farmers buy their agricultural crops from Sukabumi City, which is quite far from Nyalindung Village, as well as breeders who buy chicken feed from cities which are quite far and expensive. To reduce organic waste, this community service will conduct training on how to process organic waste into compost so that it can be used by farmers, and the use of organic waste for magot cultivation so that it can be used by chicken breeders as high protein feed. The target output of this community service is the community, farmers and breeders can make fertilizer and animal feed based on magot

Microstructure, hardness and wear resistance of AZ91 magnesium alloy produced by friction stir processing with air cooling
Authors: Iwaszko Józef , Kudła Krzysztof 
Published: June 2021

Abstract
Friction stir processing (FSP) was used to modify the surface layer of the AZ91 magnesium alloy. The treatment was carried out using a jet cooling nozzle, generating a stream of cold air and enabling intensive cooling of the friction stir processed (FSPed) zone. Single-pass FSP was carried out using a tool rotational speed of 500 rpm and travel speed of 30 mm/min. The treatment was conducted using a truncated cone-shaped tool with a threaded side surface. Strong grain refinement and microstructural changes typical for FSP were found in all the samples. Very fine, equiaxed recrystallized grains dominated in the stirring zone. In the samples modified with the jet cooling nozzle, greater grain refinement was obtained than in the case of naturally-cooled material. The average grain size in the surface part of the stirring zone was 1.4 µm and 9 µm in the samples with air cooling and with natural cooling, respectively. Both the naturally-cooled specimen and air-cooled specimen were characterized by a distinctly higher hardness than the base material. The average Vickers hardness in the stirring zone was 91 HV0.1 in the FSPed sample with the air-cooling system and 85.5 HV0.1 with natural cooling, respectively. The average Vickers hardness of the as-cast alloy was 64 HV0.1. Slightly higher wear resistance of the FSPed samples using a jet cooling nozzle was found in relation to the naturally-cooled sample. Based on the conducted research, high efficiency of the jet cooling nozzle in cooling the modified zone during friction stir processing was found.
Gate-on-drain overlapped L-shaped channel Tunnel FET as label-free biosensor
Authors: Das Suman , Sharma Bikash 
Published: June 2021

Abstract
In this manuscript gate-on-drain L-shaped channel Tunnel FET is proposed to detect various biomolecules through label-free bio-sensing detection technique. Biomolecules can be detected in the proposed structure through modulating ambipolar current between channel and drain by overlapping gate on drain thus creating a cavity. Trapped biomolecules within cavity gets immobilized. Immobilized biomolecules change the drain to channel tunneling width, thus changing the ambiploar leakage current. Drain doping and cavity length was fine-tuned to achieve better sensitivity in terms of ambipolar current and ambipolar knee voltage shift with and without presence of biomolecules. A maximum sensitivity of 3.8×107 is achieved for drain doping of 5×1019 donors/cm3 and cavity length of 60nm. A high value of sensitivity is achieved for each biomolecules when drain doping ranged from 1019 donors/cm3 to 5×1019 donors/cm3 and cavity length ranged between 40nm to 50nm. Effect of differently charged biomolecules on sensitivity has also be structured.

Abstract
Poultry and swine are the major proportion of the livestock industry in terms of output value. To meet the growing need for protein sources in these sectors, the use of biomasses coming from agro-industrial residues can be an interesting option in the coming years. This study aimed to evaluate the capacity of seven basidiomycetes to grow, detoxicate, increase protein content, and also its antioxidant activity when grew in pure Jatropha seed cake (JSC) and cottonseed cake (CSC) biomasses and mixtures containing 50% of lignocellulosic biomasses from coconut husks and Acrocomia aculeata (macauba cake). Results showed that five basidiomycetes were able to grow in these substrates. F. hepatica, P. lecomtei, and P. pulmonarius presented the highest bio-detoxification capacity. All treatments showed a reduction in total phenolic compounds (TPC) and antioxidant activity, but treatments with coconut husks showed lower reductions. Results also indicated that there are molecules produced by basidiomycetes responsible for antioxidant activity other than phenolic compounds. These results indicated that basidiomycetes could detoxify JCS and CSC biomasses, suggesting their possible use in animal feed and that the addition of coconut husks in JSC and macauba cake in cottonseed cake can promote greater colonization by fungi.

Abstract
Preclinical studies have revealed that the elevation of nicotinamide adenine dinucleotide (NAD+) levels on administration of an NAD+ precursor, nicotinamide mononucleotide (NMN), can mitigate aging-related disorders; however, human data are sparse. Therefore, we aimed to investigate whether the chronic oral supplementation of NMN can elevate blood NAD+ levels and alter physiological dysfunctions, including muscle weakness, in healthy elderly participants. We administered 250 mg NMN per day to aged men for 6 or 12 weeks (n=21 for 6 weeks, n=10 for 12 weeks) in a placebo-controlled, randomized, double blind, parallel-group trial. Chronic supplementation with NMN was well tolerated and did not cause any significant deleterious effect. Metabolomic analysis of whole blood demonstrated that the oral supplementation of NMN significantly increased the concentrations of NAD+ and NAD+ metabolites. Moreover, NMN significantly improved muscle strength and performance, which were evaluated using the 30-second chair stand test, walking speed, and grip strength, and it showed no significant effect on body composition. Thus, our evidence indicates that chronic oral NMN supplementation can be an efficient NAD+ booster for preventing aging-related muscle dysfunctions in humans.

Abstract
Exposure to xenobiotics such as Yersinia ruckeri can significantly affect bacterial infections in fish. Microplastics (MPs) may predispose fish to infection and act as carriers in pathogen transmission. Therefore, this study is designed to evaluate MPs' effect on damage caused by exposure to Y. ruckeri in rainbow trout. In this study, blood biochemical parameters and hepatic oxidative biomarkers as clinical signs were measured in the fish co-exposed to Y. ruckeri (5 and 10% LD50) and MPs (500 and 1000 mg Kg-1) for 30 days. There were no significant changes in the creatinine, triglyceride, cholesterol levels, and glutamic-pyruvic transaminase activity in the blood of fish infected with Y. ruckeri. In contrast, exposure to MPs had a significant effect on most clinical parameters. The total protein, albumin, globulin, total immunoglobulins, High-density lipoprotein, low-density lipoprotein, cholesterol levels, and γ-glutamyltransferase activity decreased, whereas glucose, triglyceride, and creatinine levels, and glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, and lactate dehydrogenase activities increased in the plasma of fish after co-exposure to MPs and Y. ruckeri. Dietary MPs combined with a bacterial challenge decreased catalase activities, glutathione peroxidase, and total antioxidant levels. However, the superoxide dismutase activity and malondialdehyde contents in the hepatocytes increased in the hepatocyte of fish co-exposed to MPs and Y. ruckeri. In conclusion, this study showed that fish exposure to MPs and simultaneous challenge with Y. ruckeri could have a synergistic effect on clinical parameters.

Abstract
PurposeThere have been few studies using mindfulness-based stress reduction (MBSR) to improve sexual function in Asian women with breast cancer. This study aimed to evaluate the impact of mindfulness intervention on female sexual function, mental health and quality of life in patients with breast cancer.MethodsFifty-one women with breast cancer were allocated into 6-week MBSR (n=26) session or usual care (n=25), without differences in group characteristics. The research tools included the Female Sexual Function Index (FSFI), the Depression Anxiety Stress Scales-21 (DASS-21), and the EuroQol instrument (EQ-5D). The Greene Climacteric Scale (GCS) was used to verify the foregoing scale. The effects of MBSR were evaluated by the differences between the post- and pre-intervention score in each scale. Statistical analyses consisted of descriptive dataset and Mann-Whitney ranked-pairs test.ResultsAlthough MBSR did not significantly improve sexual desire and depression in patients with breast cancer, MBSR could improve parts of female sexual function [i.e. Δarousal: 5.73 vs. -5.96, Δlubrication: 3.35 vs. -3.48, and Δsatisfaction: 8.48 vs. 1.76; all p <.005] assessed by the FSFI, and mental health [Δanxiety: -10.92 vs.11.36 and Δstress: -10.96 vs.11.40; both p <.001] assessed by the DASS-21.Conclusion﻿Our study revealed that MBSR can improve female sexual function and mental health except sexual desire and depression in women with breast cancer. Medical staffs can incorporate MBSR into clinical health education for patients with breast cancer to promote their overall quality of life.

Published: June 2021

Abstract
Wastewater generation from beverage industries is on the rise as the demand and consumption surge worldwide. The typical ingredients of beverages are carbonated water, saccharides, sweetener, fruit pulp, flavoring agent, color, preservatives, and salts. Only 20% concentration of the mixture goes to the bottle and the remaining becomes wastewater. However, nutrients and organics remain in wastewater and are left in sludge after going through ETP. The presence of these nutrients makes the beverage sludge useful for the cultivation that can not only decrease the application of chemical fertilizers but also combat the environmental pollution. Indian spinach and Okra have been cultivated in six different mixtures containing beverage sludge and soil to study their effects on growth, yield, food value and nutrient. Soil nutrients, organic content, EC, and pH have been analyzed to assess the suitability of sludge for cultivation. The control treatment was designed by 100% soil and gradually 20, 40, 60, 80 and 100% soil were replaced by beverage sludge in other treatments. The maximum growth of Indian Spinach and Okra was observed 120% and 125% higher at 38 days after sowing on the treatment of 80% sludge and 20% soil compared to the control treatment. Similarly, the maximum yield of Indian spinach and Okra was computed to be nine and two times higher than the control on the same treatment. Food values (ascorbic acid, β- carotene, and protein) and nutrients (Fe, Ca, Mg, K, P and Zn) were found to increase with the increasing amount of beverage sludge while those satisfy the standards of USDA. Without using any kind of fertilizer in low grade soil, the beverage sludge has shown the potentiality in both growth and yield. It turns out that beverage sludge can be used as a substitute for chemical fertilizer with an optimum amount of 80%.

Abstract
Objective: Typical endometrial polypoid adenomyoma (TPA) is a rare type of lesion in the uterine cavity or cervical canal. Although the clinical and pathologic features of TPA have been described extensively, reports on its pathogenesis and treatment remain inconclusive. This study was conducted to investigate the risk factors for endometrial TPA and recurrence and to further define the pathogenesis and treatment.Study design: This was a retrospective analysis of 488 cases of TPA and 500 cases of normal endometrium. Age, menopausal status, body mass index (BMI), reproductive history, and method of surgery were retrospectively analyzed. Among TPA cases, 360 were treated by conservative surgery. Risk factors for TPA and recurrence were assessed.Results: There was a significant difference in age, menopausal status, BMI, gravidity, and parity between the two groups (P<0.05). Age >50 years, menopause, obesity, gravidity >3, and parity >2 were risk factors for TPA (P<0.05). The incidence rate of endometriosis and adenomyosis in the TPA group was significantly higher than that in the normal endometrium group (P<0.05). Follow-up data (22–77 months) were obtained for 360 patients, revealing gravidity >3, menopause, curettage, and polyp clamp as independent risk factors for the recurrence of TPA (P<0.05). Conclusions: In addition to high estrogen levels, endometrial injury was the main contributor to TPA pathogenesis. Hysteroscopic electrotomy was the preferential treatment for TPA to avoid recurrence, especially for women with risk factors. Increasing the depth of ablation may prevent the recurrence of TPA more efficiently.

Abstract
Background: Primary health care (PHC) system is designated to be responsible for epidemic control and prevention during the outbreak of COVID-19 in China, while COVID-19 suspected cases in PHC are required to be transferred to specialist fever clinics at higher level hospitals. This study aims to understand to impact of COVID-19 on PHC delivery and antibiotic prescribing at community level in the rural areas of central China.Methods: Qualitative semi-structured interviews were conducted with 18 PHC practitioners and seven patients recruited from two township health centres and nine village clinics in two rural residential areas of Anhui province. Interviews were transcribed verbatim and thematically analysed.Results: Practitioners’ and patients’ views and perspectives on COVID-19 impacts on PHC services and antibiotic prescribing are organised into four broad themes. PHC practitioners took on a key public health role of tracing, screening and educating in rural areas, while their original role in seeing and treating patients was reduced since government required patients to be diverted. The additional work, risk, and financial pressure that PHC practitioners faced placed considerable strain on them, particularly those working in the village clinics. PHC largely diminished that related to the difficulty of PHC workforce with limited medical training and the high number of elderly patients in rural areas, and as a result of epidemic, rural patients found it more difficult to access health care. Antibiotic prescribing practices for non-COVID-19 respiratory tract infections remained unchanged and were not seen as relevant to practitioners’ knowledge of COVID-19, although overall antibiotic treatments were reduced because fewer patients were attending rural PHC clinics. Conclusions: Our study identified the considerable impact of COVID-19 epidemic on PHC in rural China. Since COVID-19 epidemic control work has been designated as a long-term task in China, rural PHC clinics now face the challenge of how to balance their principal clinical and prevention and public health roles and, in the case of the village clinics, remain financially viable.

Abstract
In recent years, many researches have been analyzed on the subject of geopolymer materials. As far as we know, the design of experiments (DOE) methods had not been used for the analysis of geopolymer containing silicon carbide sludge (SCS) waste and metakaolin components. This study was used to quantify the effects the interaction between the constituent factors and macroscopic / microstructure properties of SCS-based geopolymers (SCSGPs), by the DOE methods. Compares the correlation between the factor parameters and physical properties, which were analyzed the microstructure analysis of SCSGPs. The results of statistical analysis showed that the influencing factors of compressive strength of SCSGPs were mainly Na / Si mole ratio (NSR), Na / Al mole ratio (NAR), followed by dissolution rate of Al (DRA). In the regression curve analysis results, when the SCS replacement levels of 20%, the coefficient of b was the most influential, because the synergistic effect between metakaolin (MK) and SCS. In this study, the multivariate adaptive regression splines model provided a valid reference for the application of and future improvements in SCSGPs.

Abstract
Background The purpose of this retrospective study was to compare the clinical outcomes of anterior surgical management for cervical spinal tuberculosis by iliac bone grafts versus structural manubrium graft.Methods From January 2009 to September 2018, 23 patients with cervical spinal tuberculosis were treated with anterior debridement,autogenous structural bone graft and fixation at our spinal department. The patients were divided into 2 groups according to the different graft material,including iliac crest bone grafts in group A, structural manubrium grafts in group B. The clinical and radiographic results for the 2 groups were analyzed and compared. Results The mean duration of follow-up was 24 months. Bony fusion was achieved in all cases without failure of internal fixation. There were no significant differences between groups regarding the the operation time,blood loss,fusion time,neurological outcomes,and postoperative local Cobb angle (P>.05).However,the donor site complication rate of Group A was more than that of Group B. Postoperative ambulation time in group A was later than that of group B.The mean visual analog scale (VAS) for donor-site pain in group A was higher than group B at a week after surgery (P < 0.05).However,there was no significant difference between the 2 groups at last visit (P>.05).Conclusion Both iliac bone grafts and sternal manubrium grafts can effectively reconstruct anterior column defects in anterior surgery. However,structural sternal manubrium autografts has less complications associated with donor site morbidities than that of iliac bone.
