The effect of substitution of non-fat dry milk residue (NFDMR) by 100 and 50% of dry substances of the whey and by 50% of serum protein concentrates on the quality indices of ice cream at 12% milk fat content was investigated. To avoid the lactose crystallization when using the whey its hydrolysis was carried out. The researches resulted in establishing that the substitution of NFDMR by dry substances of whey affected negatively the dynamic viscosity of the mixture, thermal stability, air phase dispersion as well as organoleptic indices. Hydrolysis of lactose at the maturation stage prevented the crystallization of lactose during storage of ice cream. The protein content and heat stability increased when 50% NFDMR were substituted by serum protein concentrates. All studied samples with NFDMR substitution showed the decrease of the milk taste of different intensity.

An overview of ammonia physicochemical fire and explosion hazardous properties reports that this gas has its own distinctive features to be taken into account when estimating the level of fire risks of the facilities, in which it is used. In the open air at atmospheric pressure, the burning of ammonia is relatively slow, and not accompanied by a sharp increase in pressure and sound effect. Due to this, the shock waves are not formed when burning ammoniaair cloud in the open area. So, the installations using ammonia and mounted outside are not related to explosive ones. In a confined space ammonia is burning quicker, and the gas pressure increases gradually. Therefore, the explosion in the premises is dangerous for people, equipment and building units. Emissions of gas, vapor and leakage of liquid NH3 are the greatest fire and explosion hazard when operating with ammonia. When ammonia is released, the mixture of the gas with air can vary in density from the formation of gasair clouds at density lower than air density to the floatability with exceeding air density depending on the discharge conditions. Refrigeration industry is the greatest user of ammonia. The work highlights the issues of fire safety and fire protection of industrial cold stores

The article gives the results of a study of the influence of an oxygen reduced concentration and a carbon dioxide increased concentration at cold storage of apples of autumn variety on the activity of terminal oxydases, involved in the regulation of physiological and biochemical processes at the final stages of oxidation of respiration substrates. The aim of the research is to study the change of the activity of terminal oxidases depending on the cold storage duration in the gaseous atmosphere with reduced oxygen concentration and increased carbon dioxide concentration formed by a biological method using gas selective track membranes. The test subjects were the apples of autumn varieties Grushovka Yudicheva, Kordonovka and Pepin Shafranny, grown according to the generally accepted technology in the garden of collection trees of the Pavlovskaya experimental station of the N.I. Vavilov VNIIR. To form a gaseous atmosphere during the storage of autumn variety apples a new composite membrane was used, it consisted of a substrate based on the polyethylene terephthalate (PET) track membranes (TM) and a selective layer based on the organosilicon block copolymer (pore diameter 0,2 µm, selectivity 5,0). This membrane was developed in laboratories of the A.F. Ioffe PhysicalTechnical Institute and S.V. Lebedev NIISK. It was shown that during storage the change of the terminal oxidase activity depended on the apple variety, storage duration, gas composition and enzyme type. The kinetic dependences of changes in the activity of phenol oxidase, peroxidase, and catalyse enzymes on the storage duration of autumn apple varieties Grushovka Yudicheva, Kordonovka and Pepin Shafranny in the normal atmosphere (NA) and controlled atmosphere (CA) were revealed. The regression equations characterizing these dependences were obtained. The velocity constants of inactivation reactions of the enzymes studied during storage of autumn varieties in NA and CA were determined. It was established that the activity of the enzymes of phenol oxidase, peroxidase, and catalyse decreased when storing apples in CA with reduced oxygen concentration (up to 5,2±0,1%) and with increased carbon dioxide concentration (up to 3,6±0,1%) decreased. The velocity constants of enzyme inactivation reactions decreased 1,15-1,77 times depending on the variety and enzyme type. It was shown that when the apples adapted to the positive low temperature and the modified gas composition, then the terminal oxidases performed the regulatory function.
Basis of the computational domain selection in the problems of modeling a viscous flow in lowflow stages of a centrifugal compressor
Authors: Kartashov S. V , Kozhukhov Yu. V
Published: September 2022

The paper examines the problem of definition of the computational domain of the gasflow part at numerical simulation (RANS-approach) of gas flow in the low-flow stage of a centrifugal compressor at conditional flow rate Ф = 0.008. Several variations of replacing the design assembly of the flow part of the simulation stage with a gasdynamic model are considered: main working path of the stage; main working path of the stage taking into account the inlet area (inlet pipe and cowling); main working path of the stage taking into account the adjacent areas with full and partial connection with the gasflow part; main working path of the stage taking into account the friction surfaces of the stage rotor hub. It is shown that in case of axial suction into the stage the inlet pipe and cowling don’t significantly affect the parameter profile in front of the stage rotor and the gasdynamic characteristics of the stage. Modeling without areas adjacent to the path gives unsatisfactory quantitative and qualitative results. The most relevant option to take into account the losses of disk friction and leaks is a full twoway connection of adjacent areas with the flow part along the stage rotor disks, because when connecting only at the outlet of the stage rotor, the friction and leak losses are simulated, but the effect on the flow in the stage rotor is not taken into account. In some cases, it is important to consider the additional areas involved in friction losses.

With the modern variety of equipment presented on the market, it is quite difficult to make an informed choice of a particular technology. For small commercial and technological refrigeration equipment, usually, the main selection criteria are such parameters as the purchase price, reliability and energy efficiency. However, the growing requirements for workplace conditions require the inclusion in this list of characteristics that allow us to evaluate the convenience and comfort of using the purchased equipment, especially when it comes to longterm interaction with personnel. Among these parameters can be distinguished noise emission of devices This factor has a direct impact on working conditions if employees are constantly located near its source.

Authors: Gursky I. A , Tvorogova A. A
Published: September 2022

Based on cultured milk ice cream, a dessert composition at low sucrose content, enriched with food fibers, has been developed. The feature of the dessert consists in ability to keep its structure when using in an unfrozen state. The influence of gelatin and its composition including a processed product of the physically modified starch on the structure of the dessert in unfrozen state has been examined. It was established that the dessert developed had all useful qualities of cultured milk products and its structure was stable under temperature conditions of the refrigerator during two days. The use of the physically modified product (PMP) leads to the increase of the viscosity of the mixture for desserts, and also enhances the ability of their mixtures to be saturated with air. The enrichment of the dessert with food fibers allows positioning it as a food fiber source.

The amount of energy losses in hydraulic systems, determined directly by the efficiency parameter, becomes one of the basic aspects related to the design of these systems. Recently, reducing the energy consumption of hydraulic drives has become one of the most important factors in, and sometimes even the main reason for, development works focused on hydrostatic drive systems in newly designed and already deployed types of machines. The article presents an approach to improve the efficiency of such a hydraulic system based on the analytical model and also includes a case study of redesigning a hydrostatic drive system in a stationary rock breaking machine. The analysis of the calculation results showed benefits resulting from two different concepts of modifying hydraulic systems with an aim at reducing their energy consumption.

Choice of Law and Nazi-Looted Art Restitution: Cassirer v. Thyssen-Bornemisza Collection Foundation
Authors: Vastano Julia
Published: September 2022

On April 21, 2022, the Supreme Court came to an unanimous decision in Cassirer v. Thyssen-Bornemisza Collection Foundation, a case concerning the legal ownership of a valuable painting by Camille Pissarro that was appropriated by the Nazi regime during the 1930s when its Jewish owners fled to the United States. After World War II, the painting changed ownership several times, ultimately to be acquired by Baron Hans Heinrich who sold it to the Thyssen-Bornemisza Collection Foundation in the Kingdom of Spain. After sixteen years of litigation and four appeals to the Ninth Circuit, the Supreme Court vacated and remanded the case back to the Ninth Circuit. The opinion, written by Justice Kagan, contended that in a suit raising non-federal claims against a foreign state or instrumentality under the FSIA, a court should determine the substantive law by using the same voice of law rule applicable in a similar suit against a private party. This paper will introduce the facts of Cassirer, present its procedural history, and dissect its treatment before the United States Supreme Court. This analysis will conclude with a discussion of the potential implications of the Cassirer decision on future Nazi-looted art claims.

Social-Cultural Quantum Optics at a Predominantly White University: Refusing, Rebuffing and Undoing Racism through Collective Experiential Observation
Authors: Sweet Elizabeth L. , Williams-Witherspoon Kimmika , Turner Karen M. , Fornaro Elisabeth
Published: September 2022

Racism is commonly defined as prejudice plus power, but in some contexts it can be practiced as a lack of diversity, equity and inclusion. These issues have been at the forefront of popular culture and academic research for some time now, but one could argue, interest has exploded in the U.S. consciousness since May of 2020 and the video recording of the extra-judicial killing of George Floyd in Minneapolis, mirroring that of Philando Castile four years earlier in the same city. In this paper we document the ways diversity, equity and inclusion are perceived, and how those perceptions render racism (un)visible. Within this context, we introduce a framework we are calling social-cultural quantum optics (SQO). With data from two large diversity symposia at a university on the east coast that is more diverse than many coupled with our experiences at three art exhibits, we begin to construct a path unlocking small scale, quantum, determinants of racism. We argue that understanding SQO can undo its links to racism on everyday life in cities and communities where universities are located, while at the same time urging the use collective experiential observation of artistic expression to aid in data analysis.
Community Engagement through Contact Tracing Training
Authors: Line David , Kohlmeier Pamela , Mount Sarah
Published: September 2022

The COVID-19 pandemic has brought many physical, mental, and economic challenges and has provided an opportunity for academia to participate in community engagement to help support public health. Through a partnership between a university and a local health district, a contact tracing training program was developed and implemented in the late spring of 2020. That training program increased the health district’s capacity to respond to the pandemic and provided an experiential learning experience for public health students. Through this community engagement endeavor, university faculty and students helped support a local health district’s COVID-19 response efforts and, in so doing, also helped to support public health in the early stages of a global health crisis. The products of this endeavor, including contract tracers, case investigation, and trained instructors, continue to support public health contact tracing efforts in the community.

Published: September 2022

The COVID-19 pandemic has disproportionately impacted people of color, underscoring the importance of equity in the public health response. The Duquesne University Center for Integrative Health (DUCIH) is a university-wide center focused on training future practitioners and improving health equity in the Pittsburgh region. DUCIH’s initial pandemic response included a virtual adaptation of community health programs and supporting partners’ testing and vaccination efforts. In March 2021, the Allegheny County Health Department (ACHD) asked DUCIH to establish a vaccine Point of Dispensing (POD) at Central Baptist Church in Pittsburgh’s Hill District, to reach underrepresented populations. DUCIH engaged the Schools of Health Sciences, Nursing, and Pharmacy and multiple university offices to recruit an interprofessional team of 263 volunteers. From March to June 2021, the POD administered 5,652 vaccines in an underserved neighborhood, with a majority of doses administered to people of color, meeting the POD’s aim. This university-church partnership has continued with vaccine clinics and health screenings. This case study shares lessons for rapid response to public health emergencies through university-wide collaboration with community partners. Universities with health science schools should cultivate relationships with local health departments to promote awareness of these capabilities.
Establishing Principles for Community-Based Research

Published: September 2022

Academic health centers and their universities are increasingly encouraged to engage in more community-based and participatory approaches to research. Yet, traditional ethics guidelines and regulations are inadequate for addressing the dynamics of community-campus research partnerships. In this article, the authors share stories from the Community Research Collaborative (CRC), a collective of community leaders and faculty that published guidelines for community-based research (CBR). The CRC offers a case study in how a collaborative process of developing CBR guidelines can create space for partners to wrestle with the historical and present-day harms carried out in indigenous and minoritized communities in the name of science and to imagine alternative ways of working together collectively. This case study highlights the complex power dynamics inherent in community-campus partnerships and how storytelling can play a role in unearthing and addressing them. It positions the work of the CRC as incomplete and evolving while offering a foundation on which other institutions could carry out similar processes in their localities.

Ohio providers’ practices and barriers to use of reproductive life plans and long-acting reversible contraception with patients and clients
Authors: Mager Natalie DiPietro , Lucas Brad , Clark Michelle , Kelly Molly , Gabbe Patricia
Published: September 2022

Background: Creating reproductive life plans, assessing pregnancy intent, and discussing long-acting reversible contraception (LARC)can reduce unintended pregnancies and promote women’s health before and between pregnancies. The primary objective of this study was to collect information from Ohio health workers on knowledge, use, barriers, and perceptions of reproductive life plans. Secondary objectives were to determine whether health workers systematically ask female clients/patients about pregnancy intent, include information on LARC when discussing contraceptive options, or encounter barriers to these practices.Methods: A 13-item survey was sent electronically utilizing a snowball sampling design to Ohio Collaborative to Prevent Infant Mortality members and to nurses and providers working with women of reproductive age in Ohio who had current certifications listed in public access state licensure files. Chi-square tests were performed to identify associations between response to survey questions (yes/no) and respondent position (physician/advanced practice nurse/nurse).Results: Four hundred fifty-two responses were analyzed; 81% were physicians, advanced practice nurses, or nurses. Among respondents, 47% indicated routinely asking all reproductive age females if they plan to become pregnant in the next year; 47% indicated knowledge of reproductive life plans; 28% reported using reproductive life plans with clients/patients; and 72% reported discussing LARC with clients/patients. Significant differences in these practices were seen based on respondent position. The most commonly reported barriers were provider attitudes/knowledge, client/patient attitudes, workflow disruption, and time.Conclusions: Inconsistencies were seen in the delivery of these practices. There is a need for education about these practices and todevelop solutions to barriers.
Validation of the exercise self-efficacy scale (ESE-S) for increased adherence to physical activity
Authors: Nolan Rachael D. , Hallam Jeffrey S.
Published: September 2022

Background: Various self-efficacy instruments have been used to predict exercise behavior. Many of these scales have been shown tobe valid and reliable measures for the strength dimension of self-efficacy, but have overlooked the construct’s dimensions of magnitude and generality. This study established the Exercise Self-Efficacy Scale (ESE-S), a measure of the strength, generality, and magnitude dimensions of exercise self-efficacy, as a valid tool towards the promotion and adherence of routine physical activity.Methods: Using a non-experimental, cross-sectional design, the ESE-S was administered to individuals aged 18 and older (n=270) whowere conveniently recruited from a large city located in Ohio. Participants were employees of a large, national company and consentedto participate in an employee wellness campaign over a two-day period. Participants completed the 24-item ESE-S onetime and demographic data were not collected. Confirmatory factor analysis was used to examine the 4-factor hypothesized structure of the ESE-S.Results: The confirmatory analysis showed that the data did not conform to the factorial structure as originally hypothesized, but didretain a 4-four factor solution. Final factors identified from the confirmatory analysis were internal strength, external strength, generality, and magnitude.Conclusions: This study confirmed a 4-factor, 21-item factorial structure. Although the structure differed from that hypothesized, theresults showed that the tool was a valid and reliable instrument to measure the dimensions of exercise self-efficacy commonly overlooked within the literature. Public health professionals and researchers can use the instrument to measure exercise self-efficacy and develop self-efficacy based exercise promotion programs.

Communication Preferences of Young Adults During "Do Not Drink" Water Emergencies
Authors: Welch Philip , Zitko Phil , Raker Chelsea , Fallon Rebecca
Published: September 2022

Background: Rapid, accurate communication between public health officials and the community members they serve is essential for public health protection and safety. "Do not drink" water advisories are public health emergencies that periodically occur in Northwest Ohio. The City of Toledo issued a "do not drink" advisory to approximately 400,000 residents in August 2014. Most families learned about the "do not drink" advisory from television news networks. However, communication preferences among young adults differ greatly from older generations. The purpose of this study was to identify young adult communication preferences during public health emergencies such as "do not drink" water advisories.

Methods: A cross-sectional survey was used to gauge young adults' preferred method of communication during public health emergencies and to ask how they have learned about health advisories in the past. The questionnaire was administered electronically to 330 college students at a mid-size public institution in the Midwest.

Results: A total of 291 surveys were collected (88% response rate). When asked "If you have experienced a "do not drink" advisory or other public health emergency, how did you hear about it?" the majority of students (69%) reported television news stations (38%) or Social Media/Facebook (31%). When asked "how would you like to be notified during a public health emergency such as a "do not drink" water advisory?" the majority (70%) preferred text messaging.

Conclusions: Communicating rapidly with members of the community during public health emergencies is vital. Text messaging may be the best way to quickly disseminate critical information to young adults.
Human Development and Controlled Substance Prescribing in Ohio Counties
Authors: Factor Patricia , Chambers Wallace , Kauffman JoAnna “Anna” C. S. , Kinebrew Tunu , Yonley Natasha , Kauffman Ross M.
Published: September 2022

Background: Human development is a holistic measure of well-being. The American Human Development Index (AHDI) operationalizes the concept for the American context, using a composite measure of income, education, and health. This work presents the first county-level examination of AHDI for the state of Ohio and examines the relationship between human development and controlled substance prescribing.Methods: Publicly available data from the census and prior publications were compiled to calculate county-level AHDI for all 88 Ohio counties. Correlations were examined between AHDI and 4 classes of controlled substances, opioids, benzodiazepines, stimulants, and sedatives, using Pearson product moment correlation coefficient.Results: County AHDI scores ranged from 3.3 to 7.6, with mean and median values of 4.8. At the county level, human development is negatively correlated with opioid (r = -0.46, r2 = 0.22, P <0.0001) and benzodiazepine (r = -0.43, r2 = 0.18, P <0.0001) prescribing and positively associated with stimulant prescribing (r = 0.49, r2 = 0.24, P <0.0001). Neither sedative prescribing practices (r = 0.09, P = 0.40) nor median age (r = -0.09, P = 0.41) were significantly correlated with AHDI.Conclusion: There is a strong correlation between AHDI and prescribing of several classes of controlled substanc-es. Work remains to ascertain mechanisms and directionality of these relationships. Whether higher prescribing in areas with lower human development is an attempt to medicate health inequity or low human development is an additional manifestation of the opioid epidemic, this study underscores the necessity of pursuing equity in all policies.
Association of Perfluoroalkyl Substance with Lung Function in the US Population
Authors: Heinle Brenna C. , Crawford Tim N. , Paton Sara J. , Khalil Naila
Published: September 2022

Background/Aim: Perfluoroalkyl substances (PFASs) are chemical compounds used in consumer products and are linked with increases in cholesterol, thyroid disease, and pregnancy-induced hypertension. However, their association with lung function is not completely understood.Methods: Cross-sectional 2011-2012 US population data from the National Health and Nutrition Examination Survey (NHANES) were analyzed (n = 1450, aged 12 to 79 years, 50.5% females). Serum concentrations of 4 PFASs, perfluoronon-anoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorohexane sulfonic acid (PFHxS), were assessed using mass spectrometry and categorized into quartiles. Lung function was measured by spirome-try as forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and the ratio of FEV1/FVC (%). Survey weighted sex stratified adjusted linear regression analysis was used to predict lung function with PFASs quartiles.Results: In males, compared to females, all 4 PFASs serum concentrations and lung function indices were higher, except FEV1/FVC (%) which was lower than females. No association of any PFAS with decrease in lung function was seen in multivariable-adjusted models in both males and females.Conclusion: In this exploratory analysis, PFAS exposure was not associated with lung function. PFAS contamina-tion has been ongoing for many years across the US and Ohio, and cleanup efforts are now underway. The association between PFAS exposure and lung function needs further exploration in longitudinal studies.

Published: September 2022

Introduction: Dementia is a debilitating disease affecting over 50 million people. Major challenges facing patients with dementia lie in the impact of the behavioral and psychological symptoms of dementia (BPSD). The American Geriatrics Society and Dementia Action Alliance recommend against the use of antipsychotics as first-line treatment. Antipsychotics often fail to treat BPSD whereas nonmedication practices such as horticulture therapy may lessen BPSD. Guideline evidence has provided a unique opportunity for public health officials to assist in filling this vital role in the approach to BPSD management.Methods: Several studies and meta-analyses were reviewed to determine the effectiveness of horticulture therapy in managing BPSD, and evidence supports horticulture therapy as an effective method of addressing BPSD.Results: The benefits of horticulture therapy extend beyond addressing only BPSD; through multisensory stimulation, patients have increased physical activity, reduced stress, and improved sleep. Horticulture therapy has been shown to decrease the sense of loss and reestablish the patient in a familiar nurturing role, providing the patient with a sense of purpose.Conclusion: Stakeholders within the public health sector are strategically positioned to implement evidence-based interventions that address the unmet needs for the care of dementia within the community.

How My Provider Communicates: A Qualitative Exploration of Pregnant Women’s Communicative Experiences When Receiving Prenatal Care in Ohio
Authors: Evans Na’Tasha M. , Spates Kamesha , Sheu Jiunn-Jye
Published: September 2022

Background: Ohio disproportionately has one of the highest infant mortality rates in the United States. Failure to receive effective prenatal care can result in adverse pregnancy outcomes, specifically infant morbidity and mortality. Therefore, the purpose of this study is to gain a better understanding of pregnant women’s communicative experiences when receiving prenatal care in Ohio.
Methods: We interviewed pregnant women (N=30) between the ages of 19 to 39 years who were in the second or third trimester of pregnancy residing in Ohio using semi-structured interviews. The data were analyzed using a two-stage inductive thematic analytic technique.
Results: Findings demonstrated that pregnant women’s communicative experiences when receiving prenatal care in Ohio could be categorized into 4 overarching salient themes: (1) dialogue with the prenatal care provider, (2) time required for the prenatal care visit, (3) the prenatal care provider’s interpersonal and personality characteristics, and (4) continuity of care.
Conclusion: Results identified pregnant women’s communicative experiences when receiving prenatal care in Ohio. Findings may assist prenatal care providers in enhancing prenatal care outcomes in Ohio by promoting continuous dialogue, spending time with patients, displaying positive interpersonal and personality characteristics, and providing continuous prenatal care.
Strategies to Enhance Qualitative and Mixed Methods Research Instruction to Prepare MPH Students for Public Health Practice
Authors: Chatfield Sheryl L.
Published: September 2022

Background: The 2016 Council on Education for Public Health (CEPH) accreditation guidelines for Master of Public Health (MPH) programs describe skills, including qualitative and quantitative research skills while removing the requirement to structure programs around 5 designated core areas. These revised guidelines provide an opportunity to integrate qualitative and mixed methods instruction in multiple courses. The purpose of this paper is to describe process and outcomes of a project aimed at integrating qualitative and mixed methods content into core courses within the Kent State University MPH program.

Methods: Content development work was conducted from May through October 2019. The work consisted of content analysis of current core course content, research texts, practicum presentations, and feedback from alumni working in public health practice. Five key qualitative processes that support CEPH competencies and reflect current public health practice in Ohio were articulated to form a framework for new course content.

Results: New content was developed for each of the 6 current core MPH courses to address CEPH competencies, incorporate the identified 5 key processes, and to emphasize cross-methodological comparison and the complementary nature of qualitative and quantitative approaches to research questions or practice issues. Initial student responses to content were positive; further evaluation efforts are planned.

Conclusion: New content provides MPH students with skills practice associated with qualitative and mixed methods approaches to research and applied public health. To address complex public health challenges, current and future public health professionals will benefit from being able to flexibly move across methodological boundaries.
The Generalized Odd Log-Logistic Fréchet Distribution for Modeling Extreme Values
Authors: Abd El Khaleq Rania Hassan
Published: September 2022

We introduce a new extension of the Fréchet distribution for modeling the extreme values. The new model generalizes eleven distributions at least, ﬁve of them are quite new. Some important mathematical properties of the new model are derived. We assess the performance of the maximum likelihood estimators (MLEs) via a simulation study. The new model is better than some other important competitive models in modeling the breaking stress data, the glass ﬁbers data and the relief time data.
The Construction of Some New Quasi Rees Neighbor Designs Using Cyclic Shifts

Published: September 2022

Many popular neighbor designs are used in serology, agriculture, and forestry which manifest neighbor effects very much. If every treatment appears as a neighbor with other (v-2) treatments once but emerges twice with only one treatment, such designs are called Quasi Rees neighbor designs (QRNDs) in k size of circular blocks. These designs were used for counterbalancing the neighboring effects for the cases for which minimal neighbor designs cannot be constructed. In this article, various generators are constructed to obtain circular binary NDs, using cyclic shifts.
Generalized Linear Models for Loss Calculation in General Insurance
Authors: Lestari Dian , Tanujaya Raymond , Al Kafi Rahmat , Devila Sindy
Published: September 2022

In most cases, loss in non-life insurance is calculated based on claim severity and frequency and an assumption of independence. However, in some cases, claim severity depends upon the claim frequency. This paper presents the derivation of aggregate loss calculation by modeling claim severity and frequency as the assumption of independence is eliminated. The authors modeled average claim severity using claim frequency as the covariate to induce the dependence among them. For that purpose, we use the generalized linear model. After doing parameters estimation, we will obtain the calculated loss.
Bayesian Life Analysis of Generalized Chen's Population Under Progressive Censoring
Authors: Elshahhat Ahmed , Rastogi Manoj Kumar
Published: September 2022

Chen's model with bathtub shape provides an appropriate conceptual for the hazard rate of various industrial products and clinical cases. This article deals with the problem of estimating the model parameters, reliability and hazard functions of a three-parameter Chen distribution based on progressively Type-II censored sample have been obtained. Based on the s-normal approximation to the asymptotic distribution of the maximum likelihood estimates and log-transformed maximum likelihood estimates, the approximate confidence intervals for the unknown parameters, and any function of them, are constructed. Using independent gamma conjugate priors, the Bayes estimators of the unknown parameters and reliability characteristics are derived under different versions of a symmetric squared error loss functions. However, the Bayes estimators are obtained in a complex form, so we have been used Metropolis-Hastings sampler procedure to carry out the Bayes estimates and also to construct the corresponding credible intervals. To assess the performance of the proposed estimators, numerical results using Monte Carlo simulation study were reported. To determine the optimum censoring scheme among different competing censoring plans, some optimality criteria have been considered. A practical example using real-life data set, representing the survival times of head and neck cancer patients, is discussed to demonstrate how the applicability of the proposed methods in real phenomenon.

To establish cephalometric norms (skeletal and dental) for Coastal Odisha population of India and to compare it with other Caucasian norms.

The Lateral cephalograms of 60 children of 9-16 year age group with normal occlusion and pleasant profile were taken and cephalometric norms were established using Down’s, Steiner’s, Tweeds, Wits, Bjork, Jarabak, McNamara, Ricketts and Schwarz analysis.

The study concluded that Overall dimension of cranial base, maxilla and mandible are smaller in Coastal Odia children than that of Caucasians. Odia children are having more proclined upper and lower incisors and smaller upper and lower dental height in anterior and posterior region, steeper mandibular plane angle, greater upper and lower lip prominence but lesser upper lip thickness and strain than Caucasian population.
