Assessment, analysis and optimization for high temperature sliding wear process parameter with additive built nickel-base superalloy
Authors: S.P Jani , C Saravanamurthi , P Pugalenthi , Arul Sujin Jose
Published: July 2023

The nickel-base superalloy is developed through an additive manufacturing process following a metal laser sintering technique. The developed alloy is used to perform high-temperature sliding wear analysis with the different input process conditions. Applied load, sliding duration and the working temperature are the defined process environment for the investigation. The process conditions are designed with twenty-seven sets of experimental trials for statistical analysis and process assessment. The responses on surface roughness and the material loss with respect to the input process parameters are technically assessed and justifications are made with the electron microscopic images. The surface topography has been influenced due to applied load and the sliding duration. The statistical analysis has proved that the influence of temperature is less and negotiable compared to the load and time factors. From the optimization process, the optimal parameter for the experimental design is 10 N, 100 ºC and 30 min is the ultimate condition to produce the best results from the high temperature sliding wear analysis.

There has been an alarming rise in suicide attempts among indigenous people in Brazil leading to national concerns about the provision of psychosocial care and professional support. In this study, we make an attempt to understand the perspectives of professionals in assisting indigenous people from a specific group, the Iny, and identify the specific challenges of addressing issues through the mental health care system, related specifically to suicide prevention. Using a qualitative approach with participant observation and semi-structured interviews, the research included indigenous and their families assisted by three public institutions, and the professionals that work in the public psychosocial assistance. For this paper we examined the tensions, conflicts and challenges of the health care professionals at one of these institutions, a Psychosocial Care Center in the state of Goiás/Brazil. For the analysis of data, a sociocultural protocol was built to identify dialogical tensions between the different thematic-fields of mental health care. The findings reveal that the theme of suicide was an important concern in the daily work with the community, but there were significant issues related to the assumptions, methodology and meaning of care between the professionals and the community on account of which the objective of the programme to address suicide attempts had not been effective or successful. The discussion of the results raises several critical questions about possible contributions of dialogical cultural psychology in the context of indigenous health, and also has important implications for the global issue of well-being of indigenous people.
Characterizing basalt-atmosphere interactions on Venus: A review of thermodynamic and experimental results
Authors: Filiberto Justin , McCanta Molly C.
Published: July 2023

The surface of Venus is in contact with a hot (~470 °C), high pressure (92 bars), and caustic (CO2 with S, but little H2O) atmosphere, which should cause progressive alteration of the crust in the form of sulfate and iron-oxide coatings; however, the exact rate of alteration and mineral species are not well constrained. Different experimental approaches, each with its own limitations, are currently being used to constrain mineralogy and alteration rates. One note is that no experimental approach has been able to fully replicate the necessary conditions and sustain them for a significant length of time. Furthermore, geochemical modeling studies can also constrain surface alteration mineralogy, again with different assumptions and limitations. Here, we review recent geochemical modeling and experimental studies to constrain the state of the art for alteration mineralogy, rate of alteration, open questions about the surface mineralogy of Venus, and what can be constrained before the fleet of missions arrives later this decade.

Combining the new results confirms that basalt on the surface of Venus should react quickly and form coatings of sulfates and iron-oxides; however, the mineralogy and rate of alteration are dependent on physical properties of the protolith (including bulk composition, mineralogy, and crystallinity), as well as atmospheric composition, and surface temperature. Importantly, the geochemical modeling results show that the mineralogy is largely controlled by atmospheric oxygen fugacity, which is not well constrained for the near-surface environment on Venus. Therefore, alteration experiments run over a range of oxygen and sulfur fugacities are needed across a wide range of Venus analog materials with varying mineralogy and crystallinity.

Objectives: This study assessed the barriers faced by FMresidents in performing minor surgical procedures in their clinics in Tabuk, Saudi Arabia. Methodology:This observational cross-sectional study was conducted among family medicine (FM) physicians in Tabuk in June 2023. An adapted questionnaire wasdistributed online to determine the barriers family physicians may face in performing minor surgeries in their clinics. Results:A total of 35 FM physicians were included, 14 (40%) aged 25-28 years. Most of them were males (71.4%). Nearly 82.8% of the family physicians who liked performing procedures did not find it complicated, and 82.3% of those who did not like performing procedures found it complicated this association was statistically significant (P=0.001). Nearly half of the physicians (52.6%) who found it easier to refer cases with indications of minor procedures did not consider performing procedures complicated, and 93.8% of the physicians (52.6%) who did not find it easier to refer cases with indications of minor procedures did not consider performing procedures complicated this association was statistically significant (P=0.007). Conclusion: One of the biggest challenges that prevented family physicians from doing minor procedures in their clinics was a lack of time. Additionally, many physician find it easier to refer patients who need minor operations to surgical departments. The complicated nature of these operations was rated by physicians in our study based on how much they enjoyed performing them. Patients were more likely to be sent to other departments by physicians who found procedures challenging. These cases were easily and frequently referred to other surgical departments by physicians who did not enjoy conducting simple procedures, who found it complicated, and who thought their fees were too low.

Published: July 2023

Cost of cultivation of small farmers is increasing due to higher price of input of farming but they are getting profitable price. It is common phenomenon that price of crops decrease during the pick season of farming. So farmers face tremendous problems in marketing of their articles. The problems will be more tragic in case of vegetables since farmers cannot enjoy the facility of cold storage. As a remedy of this great problem the concept of contract farming has raised in 2003-2004 in India. The process of contract farming in India involves scientific and optimum use of land and farm resources for maximum output of agriculture produce. Small farmers practicing primitive agricultural methods for cultivation and harvesting of crops. But with the liberalization of Indian economy, there has been a sudden spurt in contract farming in India. Practice of this farming may bring revolution to the poor farmers by successful implementation of it.

:

Dyslipidemia and altered lipid metabolism are closely involved in the pathogenesis
and clinical manifestation of many metabolic and non-metabolic diseases. Therefore,
mitigation of pharmacological and nutritional factors together with lifestyle modifications
is paramount. One potential nutraceutical exhibiting cell signaling and lipid-modulating
properties implicated in dyslipidemias is curcumin. Specifically, recent evidence
suggest that curcumin may improve lipid metabolism and prevent dyslipidemia-induced
cardiovascular complications via several pathways. Although the exact molecular mechanisms
involved are not well understood, the evidence presented in this review suggests
that curcumin can provide significant lipid benefits via modulation of adipogenesis and
lipolysis, and prevention or reduction of lipid peroxidation and lipotoxicity via different
molecular pathways. Curcumin can also improve the lipid profile and reduce dyslipidemia-
dependent cardiovascular problems by impacting important mechanisms of fatty acid
oxidation, lipid absorption, and cholesterol metabolism. Although only limited direct supporting
evidence is available, in this review we assess the available knowledge regarding
the possible nutraceutical effects of curcumin on lipid homeostasis and its possible impacts
on dyslipidemic cardiovascular events from a mechanistic viewpoint.

Published: July 2023

Viruses cause a variety of diseases in the human body. Antiviral agents are used to prevent
the production of disease-causing viruses. These agents obstruct and kill the virus's translation
and replication. Because viruses share the metabolic processes of the majority of host cells, finding
targeted medicines for the virus is difficult. In the ongoing search for better antiviral agents, the
USFDA approved EVOTAZ, a new drug discovered for the treatment of Human Immunodeficiency
Virus (HIV). It is a once-daily (OD) fixed-dose combination of Cobicistat, a cytochrome P450
(CYP) enzyme inhibitor, and Atazanavir, a protease inhibitor. The combination drug was created in
such a way that it can inhibit both CYP enzymes and proteases at the same time, resulting in the
virus's death. The drug is not effective in children under the age of 18; however, it is still being studied
for various parameters. This review article focuses on EVOTAZ's preclinical and clinical aspects,
as well as its efficacy and safety profiles.

Published: July 2023

Background:

The emergence of drug-resistant bacteria and multidrug-resistant diseases, both of which are associated with high mortality, has posed a serious global health issue. Thiazoles and coumarins were reported as antimicrobial agents.

Objective:

This research paper aims to describe the synthesis of some novel thiazole derivatives bearing a coumarin residue as antibacterial agents

Methods:

The thiazole - coumarin hybrids were synthesized starting from the condensation of 3-acetyl coumarin (1) hydrazine carbothioamide (2) or thisemicarbazide then reacting the resulting products with different p-substituted phenacyl bromides (4a-e), hydrazonoyl chlorides (8a-e), and (11). In vitro antibacterial activity was studied in this work. In addition, molecular docking studies for the new compounds have also been carried out to investigate the binding mode of actions against the target DNA gyrase B.

Results:

Some of the newly synthesized compounds such as compounds 10b, 7, and 6b showed pro-nounced activities against Gram (+ve) and Gram (-ve) bacteria compared to a reference antibacterial agent. Compounds 10b, 7, and 6b exhibited the best binding affinity against the target

Conclusion:

We could obtain a series of precious hitherto unknown thiazole derivatives with varied antibacterial activities from cheap laboratory-available starting material following rather simple envi-ronmentally friendly techniques avoiding the use of hazardous or heavy metal-containing catalysts.

Recent advances in brachytherapy (BT) and chemotherapy, as well as consensus statements
from several different organizations, were examined in this study as they pertain to the treatment
of locally advanced cervical cancer (LACC). Since patients undergoing intensive chemotherapy
before, during, and after radiation therapy (RT) experienced significant toxicities, it was decided that
no additional conventional therapeutic options should be pursued. The use of PET-CT and MRI in the
assessment of pelvic lymph nodes and bone marrow metastases improved pelvic RT planning. It can
be concluded from the findings of the study that by administering an integrated boost for metastatic
pelvic lymph nodes in IMRT followed by MRI-guided adaptive beam therapy, patients with LACC
may benefit from modern radiation therapy methods that treat bladder and rectum tissues while shortening
treatment times.

Published: July 2023

The composite materials find various applications such as in turbine blades, helicopter blades, airplane wings, medical instruments, sports equipment, etc. They are subjected to a variety of dynamic excitations. The resonance condition is desirable for some applications such as vibration actuators, and musical instruments. And due to resonance, catastrophic failure may occur for most of the applications. Therefore, a study of dynamic behavior plays an important role in the design of materials either to avoid or to enforce resonance conditions.This work aims at the experimental investigation of vibration characteristics of composite beams. In this work, composite beams were made of glass fiber and epoxy resin with varying filler materials and their percentage. Three filler materials, viz. Calcium Carbonate (CaCO3), Nano-Clay, and Silicon Carbide (SiC) were considered for the study. The National Instruments Data Acquisition system (NI-DAQ) with a triaxial accelerometer was used to acquire the vibration data. The natural frequencies of the beams were determined from the frequency domain data and damping ratios of the beams were determined from time-domain data. Effects of filler material type on natural frequencies and damping ratios were studied. According to the research, the damping ratio values drop in the order of CaCO3, Nano-Clay, and SiC while the natural frequency values decrease in the order of Nano-Clay, CaCO3 and SiC.

The band gap dependence on the thickness dS of ultra-thin silicon dioxide films is studied using the projection augmented wave method within the density functional theory. It is shown that the value of EGS for ultrathin silicon dioxide films is less than its values for bulk crystals and increases with increasing thickness. For this, the parameters of the band structure of the tetragonal modification silicon dioxide, stishovite, were calculated for film from the thinnest oxide thicknesses 0.3 to 3.68 nm. It is found that the condition for minimizing leakage currents requires additional analysis, since it is not satisfied for all oxide dielectrics thicknesses.

Authors: Alves Santana Elisson , Francismar de Medeiros José , Lucena Cavalcante Ítalo Herbert , Teixeira Lobo Jackson
Published: July 2023

Grown in different regions of Brazil, mango is of great importance at the national level. However, mango cultivation is directly related to physiological factors such as photosynthesis, stomatal conductance and chlorophyll. Physiological factors are related to the nutritional balance of the plant. Among the nutrients, potassium (K) can be highlighted, which, despite not being a structural element for the plant, stimulates, or is part of several physiological plant processes. Therefore, an experiment was carried out with the purpose of evaluating, in the vegetative period of 'Palmer' mango, the effect of different sources of K to accelerate the maturation stage of mango branches and verify their influence on physiological indexes and chlorophyll. Treatments consisted of three ripeners and a control, which were applied directly to the branches and leaves of “Palmer” mango trees. The variables analyzed were chlorophyll A, B and Total indexes; Internal concentration of CO2; Stomatal conductance; transpiration rate; Net photosynthesis; Instantaneous Carboxylation Efficiency and Water Use Efficiency. After collecting, and analyzing the data, it was concluded that the vegetative period of the “Palmer” mango tree, in relation to the different evaluation dates, was not influenced by potassium sources. The use of T4 treatment (SpeedFol® induction mango) can provide a greater increment of chlorophyll A, B and Total than KCl and K2SO4.

BACKGROUND

Limited access to nutrition support among populations with cancer is a major barrier to sustainable and quality cancer care. Increasing use of mobile health in health care has raised concerns about its validity and health impacts.

OBJECTIVE

This systematic review aimed to determine the effectiveness of commercial or cancer-specific nutritional mobile apps among people living with cancer.

METHODS

A systematic search of the CENTRAL, Embase, PubMed (MEDLINE), and Scopus databases was carried out in May 2024. All types of intervention studies were included, except observational studies, gray literature, and reference lists of key systematic reviews. Studies were eligible for inclusion if they involved (1) patients with or survivors of cancer and (2) nutrition-related mobile apps. Studies were excluded if the nutrition intervention was not delivered via mobile app or the app intervention was accompanied by dietary counseling. The review process was conducted based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The Risk of Bias 2 and Risk of Bias in Nonrandomized Studies tools were used to assess the study quality. The Cochrane Review Manager (version 5.4) software was used to synthesize the results of the bias assessment.

RESULTS

A total of 13 interventions were included, comprising 783 adults or teenagers with cancer. Most studies focused on breast cancer (6/13, 46%), overweight (6/13, 46%), and survivors (9/13, 69%). Data on anthropometry and body composition (7/13, 54%; 387 participants), nutritional status (3/13, 23%; 249 participants), dietary intake (7/13, 54%; 352 participants), and quality of life (6/13, 46%; 384 participants) were gathered. Experimental groups were more likely to report significant improvements in body weight or composition, dietary compliance, nutritional status, and quality of life than control groups.

CONCLUSIONS

Although mobile app platforms are used to deliver nutrition interventions, the evidence for long-term efficacy, particularly in populations with cancer, remains elusive. More robust randomized controlled trials with larger sample sizes, as well as more homogeneous population characteristics and outcome measures, are warranted.

Hasil kegiatan tersebut telah meningkatkan keterampilan mereka dalam membuat produk batik tulis. Namun, daya jual batik produk mereka masih rendah di pasaran, terlebih lagi pada masa pandemi Covid-19. Setelah melakukan wawancara dan diskusi pada tahap survei, diketahui bahwa masyarakat memiliki kendala berupa kesulitan memasarkan batik tulis dan keinginan untuk memiliki batik khas Banyunibo. Berdasarkan keadaan tersebut, tim pengabdian kepada masyarakat Departemen Arkeologi UGM melakukan program pemberdayaan komunitas dengan pembinaan batik cap dan pembuatan motif batik khas Banyunibo yang terinspirasi dari relief pada Candi Banyunibo. Pengabdian masyarakat ini dilakukan menggunakan pendekatan berupa pendampingan dan pemberdayaan masyarakat dengan tujuan agar masyarakat dapat terlibat langsung dan aktif dalam pelaksanaan pendampingan ini. Batik cap sebagai alternatif diperkenalkan untuk menghasilkan batik yang tidak semahal batik tulis sehingga harganya dapat bersaing di pasaran. Motif inspirasi relief candi diciptakan melalui proses distorsi dan stilasi dari gambar asli relief candi. Motif batik yang dihasilkan dengan teknik cap tersebut juga dikombinasikan dengan teknik jumput sehingga menghasilkan motif khas Banyunibo yang diharapkan dapat meningkatkan daya jual dari batik Desa Banyunibo.

Published: July 2023

Objectives This study examined how parental and adolescent children's smartphone dependency affects their own life satisfaction and their partner's life satisfaction by applying the actor-partner Interdependence Model (APIM), and examined the structural relationship between parental and child smartphone dependency, life satisfaction, and child depression, and the mediation of life satisfaction on the relationship between parental and child smartphone dependency and child depression.
Methods For this purpose, we utilized data from the third year of the Korean Children-Youth Panel Survey (KCYPS) 2018, with a total of 2,276 adolescent children and their caregivers (father or mother) in pairs as the final data. Based on the acter-partner interdependence model (APIM), acter-effects and partner-effects were identified, and structural equations were used to test the structural relationships between variables and mediating effects through bootstrapping.
Results First, there was a acter-effect of parent-child smartphone dependency on parent-child life satisfaction, and a partner-effect of parent-child smartphone dependency on the other's life satisfaction. Comparing the magnitudes of the self and other effects, the acter-effect was larger among children, and the partner-effect was larger for the effect of child smartphone dependency on parental life satisfaction. Second, a partial mediation effect was found for the effect of parent-child smartphone dependency on child depression, mediated by parent-child life satisfaction.
Conclusions Since parent-child smartphone dependency and parent-child life satisfaction are influential on adolescent children's depression, it is necessary to provide education to prevent adolescent children's smartphone dependency and to recognize their life satisfaction positively in order to reduce adolescent children's depression, and to explore ways to increase life satisfaction by reducing smartphone dependency.
