The CO2 Mitigation and Exergo and Environ- Economics Analysis of Bio-gas Integrated Semi- Transparent Photo-voltaic Thermal (Bi-iSPVT) System for Indian Composite Climate
Authors: Tiwari Gopal Nath , Srivastava Praveen Kumar , Sinha Akhoury Sudhir Kumar , Tiwari Arvind
Published: August 2022

It is to be noted that biogas production is drastically reduced in cold
climatic conditions, especially in winter, due to a drop in ambient air temperature,
which is much below an optimum temperature of about 37℃ for fermentation of
slurry. Many methods, such as hot charging, passive/active for slurry heating, have
been tested, and it has been found that the passive heating method is neither practical
nor self-sustained. In order to make bio-gas heating self-sustained, economical, and
friendly to ecology and the environment, a new approach of Bi-iSPVT has been
adopted. Based on the finding, we have made an attempt to analyze the system in
terms of CO2 mitigation, energy matrices, and environ- and exergo-economics to have
a clean environment and sustainable climate. An analysis has been performed by using
embodied energy, the annual overall thermal exergy of the system for ecological
balance for the good health of human beings. It has been found that an energy payback
time (EPBT) for a sustainable Bi-iSPVT system is about 1.67years, along with an
exergo-economic parameter (Rex) of 0.1016 kWh/₹0.1016 𝑘𝑊ℎ/₹.

Published: August 2022

Abdominal pain (AP) is a very common complaint that renders it elusive to
diagnose in most instances. After history and evaluation narrow the list of differential
diagnoses (DD), ancillary investigations including laboratory tests and radiological
modalities are ordered. Of note, these adjuncts will only help the clinician who bears a
presumptive diagnosis on the mind. Non-invasive, repeatable and cost-efficient options
such as ultrasound are preferred initially, although, in most instances, more specific and
definitive information warrants advanced imaging techniques including computed
tomography and contrast studies. Laboratory work-up needs to be tailored to the
individual based on findings on evaluation. ECG, complete blood count and blood
chemistry can provide inappreciable clues for specific diagnoses while none will be
sufficient per se. Urinalysis and specific cultures including stool studies will expedite
recognition of urinary tract infection, amebiasis and other infections when indicated.
B-hCG level can prevent unwanted exposure to radiation and drug effects on an
unrecognized pregnant woman. Thus, all these adjunctive investigations should be
included in the management plan individualized to the patient, based on the history and
evaluation findings.
Treatment and Resuscitation of the Patient with Acute Abdominal Pain

Published: August 2022

Provision of airway patency, effective breathing and gas exchange and
circulatory functions producing adequate perfusion (ABC) are vital elements in all
emergent and critical patients. Initial resuscitation should begin with control in a
primary survey both in the field and in the hospital in the management of the patients
with abdominal pain. In a patient whose respiratory patency is under threat, evaluation
and management of the inflammatory process in the abdomen should not be considered
before this is resolved. Differential diagnosis and proper management of abdominal
pain follow the primary survey, resuscitation and resolution of vital threats. IV fluid
therapy and pain management are commenced as prompted by the general condition.
Prehospital providers should operate in communication with the command control
center in this context. “Tubes or fingers for all orifices” can be accepted as a general
approach for the moribund patient to monitor the clinical course. In the hospital, the
emergency physician should relieve the pain expediently after evaluating and recording
the initial vital signs and findings on systemic examination. Antiemetic therapy and
other symptomatic measures should be individualized for the given patient.

Background/Aim: During ovarian cancer (OC) debulking surgery, the surgeon can examine the peritoneal cavity for malignant cancer cells with peritoneal washing (PW) cytology. The goal of this study was to examine the significance of peritoneal washing as a prognostic indicator for ovarian cancer patients. Patients and Methods: Information considering the prognostic factors of OC and their impact in PW’s result was collected, compared, and combined. Results: Omental metastasis, tumor type, tumor invasion, tumor size, tumor grade/ stage, tumor’s cytoreduction, and recurrence affect both the peritoneal washing result and the patient’s prognosis. The correlation that most of the above factors have with a positive PW and dismal prognosis, led us to the assumption that PW has a significance as a prognostic indicator. Conclusion: The significance of PW as a prognostic indicator remains an assumption.

Published: August 2022

A potentially curative treatment scheme for gastric cancer is considered futile without a proper surgical resection. An oncological, surgical resection for gastric cancer prerequisites a proper resection of the stomach, and a D2 lymph node dissection followed by reconstruction of the gastrointestinal tract continuity. Recently, as the favorable impact of organ preserving surgery on functional outcomes has been increasingly appreciated; distal gastrectomy represents a valid alternative to total gastrectomy provided that the proper oncological principles are not violated. However, the appropriateness of distal gastrectomy as a valid type of resection becomes synonymous with achieving a negative proximal resection margin. The purpose of the present study was to assess the optimal distance between the tumor and the resection margin in a gastrectomy with curative intent, performed for gastric cancer, by reviewing the relevant literature. Having in mind, the well documented discrepancy between the gross and the pathologic boundaries of the tumor, pitfalls might be encountered. Current published guidelines have used a “safety distance” i.e., >4 or 5 cm between the proximal macroscopic tumor border and the proximal resection margin in order to guarantee a negative resection margin on pathology. An increased distance of safety is currently proposed in high-risk tumors such as tumors of the diffuse histological type.

Background/Aim: The proton pump inhibitors were reported to affect the blood concentration of tacrolimus. Vonoprazan fumarate is a new acid suppressant with potent acid inhibitory effects. There have been no reports concerning the effect of vonoprazan on the tacrolimus blood concentration in liver transplant (LT) recipients. Patients and Methods: Eighteen living donor liver transplantation (LDLT) recipients who switched from proton pump inhibitors (PPIs) to vonoprazan between 2016 to 2018 were enrolled in this retrospective study. We investigated blood levels of tacrolimus, and liver and renal function before and after the change from PPIs to vonoprazan. Results: The median C0/D of tacrolimus before conversion, 3 months after conversion, and 6 months after conversion were 2.33, 1.53, and 1.89, respectively, and there was no significant difference. Conversion from another PPI to vonoprazan was not associated with a worsening liver function. The estimated glomerular filtration rate was significantly worse after conversion. Conclusion: Vonoprazan can be safely administered to LT recipients receiving tacrolimus during the stable period.

Abstract. Ag8Ge1-xMnxTe6 solid solutions with different manganese content (x = 0; 0.05; 0.1; 0.2) were prepared by alloying and further pressing the powders under a pressure of 0.6 GPa. By the X-ray diffraction studies have shown that the introduction of manganese atoms leads to the compressibility of the Ag8Ge1-xMnxTe6 lattice. All p-type samples had high resistance below the transition at temperatures of 180 - 220 K. An increase in electrical conductivity in the range of 220 - 300 K was analyzed using the Mott ratio; at temperatures T > 320 K, semiconductor behavior is observed in all compositions. The highest thermoelectric figure of merit ZT = 0.7 at 550 K was obtained for a solid solution of the composition Ag8Ge1-xMnxTe6 (х = 0.05).

We study radiation damage accumulation in alphapolymorph of gallium oxide (α-Ga2O3) epitaxial layers under irradiation with 40 keV monatomic P and 140 keV molecular PF4 ions. The distribution of stable structural damage is bimodal in both cases. The growth rate of the surface disordered layer under PF4
ion irradiation is significantly higher than that under monatomic P ion bombardment. At the same time, monatomic ion irradiation is more efficient in the bulk defect peak formation. Thus, the density of displacement cascades strongly affects the formation of stable damage in α-gallium oxide. The doses required to create the same level of disorder in the metastable α-polymorph are higher than that in the thermodynamically stable β-Ga2O3. Mechanisms of damage formation in these polymorphs are
different.

Предложен новый подход для реализации сильного электрон-фононного взаимодействия в гетероструктурах. Исследована трехслойная структура, состоящая из ионной подложки, полупроводниковой пленки и покрывающего диэлектрика, в роли которого может выступать воздух или вакуум. Вблизи гетерограницы возникают интерфейсные оптические фононы, параметры которых определяются главным образом диэлектрическими свойствами подложки. Показано, что наличие интерфейсных фононов меняет величину эффективной массы носителей в пленке. В зависимости от степени ионности подложки это изменение может варьироваться от нескольких десятков до сотен процентов. Показано, что во многих полупроводниковых пленках возможна реализация условия сильного электрон-фононного взаимодействия. При этом измерение эффективной массы носителей в одинаковых пленках, расположенных на разных подложках, позволит проследить переход от слабого электрон-фононного взаимодействия к сильному. Ключевые слова: электрон-фононное взаимодействие, эффективная масса, интерфейсные фононы, полярон, тонкие пленки.

The electrical and photoelectric characteristics of the Ga2O3/n-GaAs structures have been studied. A gallium oxide film was obtained by HF magnetron sputtering on n-GaAs epitaxial layers with concentration of Nd = 9.5ˑ1014 cm–3 concentration. The thickness of the oxide film was 120 nm. Measurements at a frequency of 106 Hz have shown that the capacitance-voltage and conductance-voltage dependences are described by curves characteristic of metal-insulator-semiconductor structures and exhibit low sensitivity to radiation with λ = 254 nm. When operating on a constant signal, the samples exhibit the properties of a photodiode and are able to work offline. The photoelectric characteristics of the detectors during continuous exposure to radiation with λ = 254 nm are determined by the high density of traps at the Ga2O3/GaAs interface and in the oxide film.
The Factors Influencing Older Adults’ Decisions Surrounding Adoption of Technology: Quantitative Experimental Study
Authors: Moxley Jerad , Sharit Joseph , Czaja Sara J
Published: August 2022

Background

The rapid diffusion of technology apps may support older adults’ independence and improve the quality of their lives. Models for predicting technology acceptance in older adults are sparse, based on broad questions related to general technology acceptance, and largely not grounded in theories of aging.

Objective

This study aimed to use a mixed methods approach involving 5 technologies to comprehensively assess the causal relationships among factors that influence older adults’ willingness to adopt the technologies.

Methods

In total, 187 men and women aged 65 to 92 years participated in the study. Participants were given presentations on 5 different technologies spanning domains that included transportation, leisure, health, and new learning and provided ratings of each technology on various measures hypothesized to influence adoption. They were also administered other instruments to collect data on their actual and self-assessed cognitive abilities, rates of discounting of the technologies with respect to willingness to invest time to attain higher skills in the technologies, general technology experience, and attitudes toward technology. We used the machine learning technique of k-fold cross-validated regressions to select variables that predicted participants’ willingness to adopt the technologies.

Results

Willingness to adopt technologies was most impacted by 3 variables: perceived value of the technologies (β=.54), perceived improvement in quality of life attainable from the technologies (β=.24), and confidence in being able to use the technologies (β=.15). These variables, in turn, were mostly facilitated or inhibited by the perceived effort required to learn to use the technologies, a positive attitude toward technology as reflected in the optimism component of the technology readiness scale, the degree to which technologies were discounted, and the perceived help needed to learn to use the technologies.

Conclusions

Our findings demonstrate that participants’ willingness to adopt technologies is mainly determined by perceptions of 3 aspects of the technologies; these aspects possibly mediate many relationships with willingness to adopt. We discuss the implications of these findings for the design and marketing of technology products for older consumers.
Association between Severity of Depressive Symptoms and Human-Smartphone Interactions: A Longitudinal Study (Preprint)
Authors: Yang Xiao , Knights Jonathan , Bangieva Victoria , Kambhampati Vinayak
Published: August 2022

BACKGROUND

Various behavioral sensing research studies have found depressive symptoms are associated with human-smartphone interaction behaviors, including lack of diversity of unique physical locations, entropy of time spent in each location, sleep disruption, session duration, and typing speed. These behavioral measures are often tested against a total score of depressive symptoms and the recommended practice to disaggregate within- and between-person effects in longitudinal data is often neglected.

OBJECTIVE

We aimed to understand depression as a multi-dimensional process and explore the association between specific dimensions and behavioral measures computed from passively sensed human-smartphone interactions. We also aimed to highlight the non-ergodicity in psychological processes and the importance of disaggregating the within- and between-person effects in the analysis.

METHODS

Data used in this paper were collected by Mindstrong Health, a telehealth provider that focuses on individuals with Serious Mental Illness (SMI). Depressive symptoms were measured by DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure – Adult every 60 days for a year. Participants’ interactions with their smartphones were passively recorded and five behavioral measures were developed and expected to associate with depressive symptoms according to either theoretical proposition or previous empirical evidence. Multilevel modeling was used to explore the longitudinal relations between severity of depressive symptom and these behavioral measures. Furthermore, within- and between-person effects were disaggregated to accommodate the non-ergodicity commonly found in psychological processes.

RESULTS

This study included 982 records of DSM Level 1 depressive symptom measurements and corresponding human-smartphone interaction data from 142 participants (AgeM = 55.1; of whom 30% are female). Anhedonia was significantly associated with app count (γ_10= -0.14, p =0.01, within-person), and marginally significant associations was found between anhedonia and nighttime smartphone use (γ_30= 0.07, p =0.10, within-person effect), typing time interval (γ_05= 0.88, p =0.07, within-person effect), and session duration (γ_04= -0.29, p =0.07, between-person effect). Depressed mood was significantly associated with typing time interval (γ_05= 0.88, p =0.04, within-person effect), and session duration (γ_05= -0.37, p =0.03, between-person effect).

CONCLUSIONS

This study contributes new evidence of associations between human-smartphone interaction behaviors and the severity of depressive symptoms from a dimensional perspective, and it also highlights the importance of considering the non-ergodicity of psychological processes and analyzing the within- and between-person effects respectively.
A STUDY ON THE ANTECEDENTS OF CONFLICT MANAGEMENT STYLES: THE ROLE OF MINDFULNESS AND EMOTIONAL INTELLIGENCE
Authors: KALAFATOĞLU Yaprak
Published: August 2022

Aim: Mindfulness means focusing on the moment with attention and a positive attitude. It is a Buddhist concept that was secularized by Kabat-Zinn (2005) and brought to the world of science, and its effects in different areas such as psychology, business administration, health sciences, guidance, and psychological counseling were studied. Numerous studies have found that mindfulness has positive effects on an individual’s attitudes and behaviors. A less studied concept regarding the influence of mindfulness is conflict management styles. In this research, the mediating role of emotional intelligence on the relationship between trait mindfulness and cooperative conflict management styles was determined.Method: Data were collected from 193 white-collar personnel who are employed in the public and private sectors using the convenience sampling method.Findings: Trait mindfulness was related to integrating and compromising conflict management styles. The mediation analysis was conducted with SPSSS Process Macro and it was found that emotional intelligence didn’t act as a mediator.Results: The integrating and compromising styles predict trait mindfulness. The theoretical contributions of the research were discussed and suggestions were given to the practitioners.
Pemodelan Pembangkit Listrik Tenaga Bayu Kecepatan Variabel untuk Analisis Aliran Daya
Authors: Rudy Gianto
Published: August 2022

Akhir-akhir ini, pemanfaatan energi angin melalui pembangkit listrik tenaga bayu (PLTB) kecepatan variabel untuk pembangkitan daya listrik telah mengalami peningkatan yang cukup signifikan. Hal ini berbanding terbalik dengan PLTB kecepatan tetap yang penggunaannya semakin menurun. Pesatnya perkembangan PLTB kecepatan variabel ini terjadi terutama karena PLTB tersebut dapat mengekstraksi atau menangkap energi angin secara lebih optimal dibandingkan PLTB kecepatan tetap. Operasi kecepatan variabel pada suatu PLTB dapat dicapai melalui aplikasi doubly fed induction generator (DFIG) sebagai konverter energi utamanya. Untuk dapat menyelidiki atau menganalisis sistem tenaga yang mengandung PLTB, langkah penting pertama yang harus dilakukan adalah pemodelan dari seluruh komponen sistem tenaga (termasuk PLTB). Analisis terhadap sistem tenaga ini biasanya dilakukan untuk mengevaluasi kinerja atau penampilan sistem tenaga tersebut. Makalah ini membahas pemodelan PLTB kecepatan variabel yang berbasis DFIG untuk digunakan pada analisis aliran daya sistem tenaga listrik. Usulan model PLTB tersebut diperoleh berdasarkan formula-formula yang menghitung daya dan rugi-rugi daya dari PLTB. Pemodelan konverter elektronika daya dari DFIG yang biasanya cukup rumit tidak diperlukan dalam proses pembentukan model. Lebih lanjut, tidak seperti pada metode-metode yang sebelumnya telah dipublikasi, yaitu dua model yang berbeda harus digunakan untuk mengakomodasi analisis aliran daya pada kondisi subsinkron dan kondisi supersinkron, pada makalah ini PLTB yang berbasis DFIG tersebut cukup direpresentasikan melalui satu model matematis. Model tersebut dapat digunakan untuk menyatakan DFIG, baik pada kondisi subsinkron maupun kondisi supersinkron. Model ini kemudian diintegrasikan ke dalam analisis aliran daya untuk mengevaluasi kinerja keadaan mantap sistem. Hasil-hasil dari studi kasus juga disajikan pada makalah ini. Pada studi kasus tersebut, dilakukan penyelidikan terhadap aplikasi dari metode yang diusulkan pada sistem tenaga terinterkoneksi yang mengandung PLTB. Hasil penyelidikan mengonfirmasi validitas usulan model DFIG.

Electrical energy consumption has increased annually. It is in line with the fulfillment of electricity sales for the last five years (2013-2017) with a 5.1% growth per year. Muna and Buton are large islands in Southeast Sulawesi with a population of 360,682 and an area of 7,712.18 km2. Muna and Buton are two main cities in Southeast Sulawesi that are developing rapidly. Those two regions are relatively rich in natural potential, promoting local economic growth. The primary source of electricity for both regions is Buton. Current electricity consumption in Muna and Buton is relatively high, with a peak load of 37 MW primarily fulfilled by diesel power plants (pembangkit listrik tenaga diesel, PLTD) of 30.15 MW. The government's target to achieve a new renewable energy mix (NRE) of 23% in 2025 and 31% in 2050 is contrary to the situation of generations in Muna and Buton, which is currently still dominated by PLTD. The planning was conducted by looking at its effect on the cost of generation construction, reserve margin, energy mix, and total cost. The desired optimization value was achieved through several performed scenarios, i.e., an isolated or pre-interconnection scenario, assuming each system was separated, and an interconnection system, assuming that interconnection was performed in Muna and Buton system. The optimization method was carried out using mixed-integer linear programming (MILP) by employing the OSeMOSYS software platform. The optimization results show that the Muna-Buton generation expansion planning has been successfully carried out. Of the several performed scenarios, the scenario with the interconnection system can be selected as the best option. It is based on the total cost value and reduced generation costs of 1,073 IDR per kWh in 2022 and 1,362 IDR per kWh in 2047, with an average of 1,202 IDR per kWh.

Penggunaan energi listrik di gedung-gedung pemerintahan terkesan kurang memperhatikan ketentuan penghematan energi listrik. Pada kenyataannya, banyak ruangan yang masih menyalakan lampu penerangan pada siang hari meskipun pencahayaan ruangan sudah cukup terpenuhi oleh sinar matahari. Penggunaan air conditioner (AC) banyak yang tidak sesuai dengan volume ruangan dan jumlah orang yang beraktivitas dalam ruangan tersebut. Hal ini menyebabkan terjadinya pemborosan energi listrik. Universitas Negeri Gorontalo (UNG) mempunyai permasalahan dalam pemborosan energi listrik. Berdasarkan data dari bagian rumah tangga UNG, penggunaan daya listrik bulan Maret 2021 adalah 65.291.330 VA. Hal tersebut sangat membebani anggaran biaya operasional universitas (±60,30% dari dana operasional rumah tangga UNG). Tujuan penelitian ini adalah menganalisis intensitas penggunaan energi listrik dan menetapkan kebijakan penghematan penggunaan energi listrik. Studi penelitian dilakukan di Fakultas Teknik UNG. Metode penelitian yang digunakan adalah metode analisis audit intensitas konsumsi energi (IKE). Tingkat pencahayaan ruangan sesuai cahaya lampu penerangan dan cahaya matahari yang masuk dalam ruangan diukur secara langsung dengan lux meter dan dianalisis sesuai ketentuan Standar Nasional Indonesia (SNI) 6197-2011. Penggunaan energi listrik pada ruangan ber-AC maupun tidak ber-AC dianalisis menggunakan metode analisis IKE. Tingkat penggunaan energis mengacu pada standar efisiensi sesuai Peraturan Menteri ESDM No. 13 Tahun 2012. Hasil penelitian menunjukkan bahwa rata-rata 23,43% dari 233 ruangan memiliki intensitas pencahayaan melebihi standar SNI. Penggunaan daya listrik pada ruangan ber-AC selama satu bulan (26 hari kerja) adalah 14,73 kWh/m2/bln. Berdasarkan standar efisiensi Peraturan Menteri ESDM, hal ini termasuk pada kategori agak boros. Penghematan energi listrik dilakukan dengan menerapkan efisiensi sistem pencahayaan ruangan dan penggunaan AC dengan daya sesuai standar kebutuhan kesejukan ruangan serta penerapan pola hidup hemat energi listrik.
Impact of Decadence of Education on the National Security and Sustainable Governance in Nigeria
Authors: Ojewunmi Emmanuel Adelekan
Published: August 2022

This paper investigates the causes for the decadence and continuous decline of education and its impact on the national security and sustainable governance in Nigeria. The paper with the use of descriptive design along with the secondary data collection, analyses the various negative ways the continuous and incessant closure of the public educational institutions in Nigeria can have on the national security and sustainable democratic governance in Nigeria state. The finding of this paper is that the government has not done enough to arrest the situation, and that the country is therefore heading toward total disintegration. The paper also believes that the inadequate budgeting for the educational sector has contributed greatly to the inefficiency of Nigeria’s educational institutions at all levels. The paper therefore recommends that the governments should revisit their budget provisions by voting more funds for this important sector and as a matter of urgency, the government at the central levels should speedily resolve the ongoing strike of public university staff, while those closed institutions since February 2022 be opened within a shortest period in order to return the students back to their schools.

Democracies considered advanced have legislation regulating lobbying activities as an important element in the representation of interest groups, but the relationship of these groups with the State integrates elements of corporate social responsibility. What has not been considered is how public servants view this regulation as an interested party. The present study observes the perception of the Federal District Legislative Chamber employees on the elements necessary for effective social responsibility in government relations.

The digital transformation in agriculture is underway and has increasingly attracted several segments that perceive the potential of technologies to leverage agricultural production, through the use of technological resources that enable rural planning, cost reduction allied to the preservation of resources. natural resources, such as precision agriculture. This article aims to identify the contributions of technological training in sustainable agriculture made possible with the use of information and communication technologies [ICTs] in the Brazilian context and its implications for the economic and social development of the territories. The perceived problem is that the lack of adoption of ICTs by social and economic agents delays the process of territorial development. Based on the hypothesis that the use of ICTs in technological training in sustainable agriculture can contribute to the economic and social development of the territories, a literature review of articles published in journals was carried out, from 2017 to May 2022. The main observed results highlight that the use of ICTs requires greater engagement of social and economic agents from different territories, in order to guarantee the implementation of public policies that expand connectivity and the training of actors.
The Black Feminine: Women and Their Positioning in the Patriarchal Societies
Authors: Shafi Uzma
Published: August 2022

The Westernization of black women in the US and throughout the diaspora, via ideological apparatuses such as education and the labour market, is symptomatic of the West’s attempt to interpellate and embourgeois them, post the 1970s, to fit, converge, with their role as professional managers and service workers in the globalization efforts, for equality of opportunity, recognition, and distribution with their white male counterparts, in spite of some obstacles and roadblocks. This Westernization of black women by global capital, leading to what Paul C. Mocombe calls black feminine patriarchy, is not liberatory; instead, it is integrative, oppressive, exploitative, and a threat to all life on earth as black women become feminine patriarchs recursively organizing and reproducing the Protestant Ethic and the spirit of capitalism of their former white enslavers despite its effects on black family life, the climate, and all life on earth.
Cost–effectiveness analysis of pembrolizumab for patients with advanced esophageal cancer at PD-L1 combined positive score ≥10
Authors: Xie Qian , Luo Yaxin , Peng Xingchen
Published: August 2022

Aim:
Due to the high price of pembrolizumab, it is still unknown whether the use of pembrolizumab for advanced esophageal cancer would be a cost-effective option for patients whose PD-L1 combined positive score is ≥10.
Methods:
A Markov simulation model was performed based on clinical trial KEYNOTE-181. Incremental cost–effectiveness ratios were calculated to compare the two treatments.
Results:
The total costs were US$193,575.60 and $8789.24 for pembrolizumab and chemotherapy treatment, respectively. The pembrolizumab group produced 0.93 quality-adjusted life years (QALYs), while the chemotherapy group produced 0.58 QALYs. Thus, patients in the pembrolizumab group spent an additional US$184,786.36 and produced 0.35 QALYs more than the chemotherapy group, which resulted in an incremental cost–effectiveness ratio of US$527,961.03 per QALY.
Conclusion:
For patients with advanced esophageal cancer whose PD-L1 combined positive score is ≥10, pembrolizumab is not a cost-effective second-line therapy versus chemotherapy from the US payer perspective.
Development of Decision Making Android Model for Farmers

Abstract: Agriculture is the backbone of our country and contributes almost 18 percent of the GDP, according to the Department of Agriculture, Cooperation, and Farmer Welfare’s 2018–2019 annual report. Agriculture is the largest sector of the Indian economy, employing about half of the labour force. However, farmers might not always benefit from the market for their products. Producing the fruits and vegetables, India is second largest in world according to Department of Agriculture, cooperatives and Farmer Welfare’s annual report for 2020–2021 yet, farmers there are experiencing financial hardship due to crop failures. Marketing veggies from growers to consumers is fraught with issues. Transportation and the seasonality of fruit are the two rather significant obstacles that farmers who grow vegetables must overcome. The perishability of the goods, the seasonality of manufacturing, the bulkiness of the products, and the price difference between buying and selling were the less severe constraints. The objective of this project is to create a system that helps farmers choose the best crop based on soil characteristics, environmental factors like temperature, soil humidity, humidity and market demand, as well as technological advancements like crop suggestions and decision-making models to help farmers understand the demand for perishable crops.

Abstract: There are many approaches to the RTL design Verification. The different types of approach can be software simulation based, hardware accelerated simulation, formal verification etc. It helps to verify the correctness of the design, functional implementation and enhancing the design at every stage. Transition to Systemverilog has been done to cope up with the shrinking size of technology nodes and Time to market. In advanced times, the systems are to be designed in a generic way. The number of registers in the architecture increases as the number of combinations increases. Additionally, memory size is increasing as a result of the increased market need for data storage. An innovative approach is needed to access and validate the large variety of registers and the memory. A SystemVerilog class library called UVM was created specifically to support the creation of modular, reusable verification components and test-benches. Since it is an industry standard, you can use UVM IP that you obtain from other sources in your environment. You'll need to construct everything from scratch if you don't utilise UVM.
