Authors:   Universitas Gadjah Mada, Santosa Langgeng Wahyu
Published: December 2021

Mata air merupakan sumber air bersih potensial yang dimanfaatkan masyarakat di Lembah Banjarasri Kecamatan Kalibawang Kabupaten Kulonprogo. Tujuan penelitian ini adalah menganalisis karakteristik hidrogeomorfologi mata air di daerah penelitian. Kajian hidrogeomorfologi menjelaskan tentang aspek-aspek geomorfologi yang berpengaruh terhadap karakteristik pemunculan mata air pada setiap satuan bentuk lahan. Hasil penelitian menunjukkan bahwa secara geomorfologi di Lembah Banjarasri terdapat 2 mata air yang muncul pada bentuk lahan lerengkaki perbukitan struktural terdenudasi kuat, dengan debit aliran kecil, karena dipengaruhi oleh kemiringan lereng yang sangat curam, tipisnya lapisan tanah sebagai media infiltrasi air hujan, dan jenis material penyusun berupa batuan andesit tua yang relatif kedap air. Terdapat 12 mata air pada bentuk lahan lerengkaki perbukitan struktural terdenudasi sedang tersusun oleh batugamping Formasi Sentolo, berstruktur percelahan dan retakan, sehingga permeabilitas dan prorositas batuan tinggi dan berpotensi memunculkan mata air. Hanya terdapat 4 mata air yang muncul pada lerengkaki perbukitan struktural terdenudasi ringan, karena faktor material penyusun berupa batuan beku andesit tua Formasi Kebobutak. Pada bentuk lahan dataran aluvial terdapat 3 mata air, karena faktor topografi yang relatif datar hingga landai, dan tebalnya endapan aluvium, serta tidak ada kontrol struktur yang tegas sebagai faktor pemunculan mata air.

Potencijalna toksičnost titanija
Authors: Dežulović Lara , Čanadi Jurešić Gordana
Published: December 2021

Titanij se široko primjenjuje zbog svoje biokompatibilnosti i dobrih biomehaničkih svojstava. Pokazuje dobru sposobnost vezanja za živo tkivo i kosti pa se često upotrebljava za zubne, ortopedske i srčane implantate. Upotrebljava se kao čisti titanij ili kao legura na bazi titanija, gdje dodatak drugog elementa titaniju omogućuje dobivanje boljih svojstava od samoga titanija. Unatoč inertnosti, titanij je i dalje podložan koroziji i otpuštanju štetnih metalnih iona u organizam. Većina studija pokazuje da je titanij izrazito biokompatibilni materijal, međutim određene studije ukazuju da materijali od titanija mogu postati nekompatibilni i prouzročiti štetne učinke. S obzirom na široku upotrebu titanija, javljaju se pitanja o mogućoj štetnosti titanija. Stoga je važno i dalje provoditi toksikološka ispitivanja, pomno procijeniti i ispitati potencijalnu štetnost titanija te provjeriti potencijalne zdravstvenerizike za ljude i za ekosustav.

Authors: Kenđel Jovanović Gordana , Krešić Greta , Pavičić Žeželj Sandra
Published: December 2021

Aim: To evaluate students’ dietary vitamin D intake according to characteristics and habits concerning daily sunlight exposure. Methods: The study included 403 students of the University of Rijeka, Croatia that fulfilled questionnaire about their characteristics, habits, physical activity, supplement use, diet, and their daily sunlight exposure. For assessing diet quality, the Dietary inflammatory index (DII®) was used. Results: Average dietary vitamin D intake was 2.76 μg/day, statistically highest among men (p<0.01), medical sciences universities’ students (p<0.01), students with obesity (p=0.03), highly physically active (p=0.02) and smokers (p=0.01). Major dietary vitamin D sources were fish (42%, p<0.01) and meat and meat products (31%). Students that more frequently expose themselves to the sunlight were mostly men, overweight, moderately physically active, dietary supplements users, and had a diet with more anti-inflammatory potential, higher dietary vitamin D intake and its major dietary sources. Those who rarely and never used a sunscreen had a more anti-inflammatory diet and higher vitamin D and its major food sources intakes. Diet with more pro-inflammatory potential had students that rarely or never directly expose themselves to the sunlight, likewise the students that frequently used sunscreen. Those subgroups also had the lowest dietary vitamin D intake. Conclusions: The average dietary vitamin D intake by investigated university students satisfied only the fifth of the recommended daily vitamin D intake. Students with habits that can influence the lower synthesis of vitamin D may increase the risk of diseases related to bone health, immunity and inflammation in their future life. Provided results about students’ habits of their exposure to the sunlight might be useful for public health messages toward sufficient sunlight exposure, diet quality with more anti-inflammatory potential, vitamin D supplements use, and vitamin D deficiency prevention.

Published: December 2021

Cilj: Porod carskim rezom kontinuirano se povezuje s povećanim rizikom za pojavu komponenti metaboličkog sindroma kod ispitanika u općoj populaciji, dok su podatci za bolesnike sa shizofrenijom manjkavi i proturječni. U ovom smo istraživanju ispitali pridonosi li, i u kojoj mjeri, vrsta poroda vrijednostima indeksa tjelesne mase (ITM) te koncentracijama lipida i glukoze u plazmi na dvjema skupinama bolesnika sa shizofrenijom koji ne primaju terapiju: u bolesnika s prvom epizodom shizofrenije (N = 48) i u kroničnih bolesnika neadherentnih prema antipsihotičnoj terapiji (N = 83). Ispitanici i metode: Podatci o vrsti poroda i neadherentnosti prema antipsihotičnoj terapiji prikupljeni su iz autoanamneze i heteroanamneze. Određivanje ukupnog kolesterola, LDL kolesterola (engl. low density lipoprotein cholesterol), HDL kolesterola (engl. high density lipoprotein cholesterol), triglicerida i glukoze u plazmi realizirano je nakon 12-satnog gladovanja. Rezultati: Učestalost poroda carskim rezom iznosila je 8,4 %. Koncentracije triglicerida i vrijednosti ITM-a bile su značajno više u bolesnika rođenih carskim rezom u odnosu na bolesnike rođene vaginalnim porodom: 1,5 (0,6 – 4,3) vs. 1,1 (0,3 – 3,1); z = -2,21, p = 0,027. Vrsta poroda pridonosi s približno 3,3 % varijabilnosti koncentracija triglicerida. Zaključci: Naši rezultati upućuju da vrsta poroda utječe u manjoj mjeri na koncentracije triglicerida u plazmi u bolesnika sa shizofrenijom koji nisu na terapiji antipsihotičnim lijekovima. Porod carskim rezom predstavlja rizični čimbenik za povišene koncentracije triglicerida.

Authors: Zimmermann Bettina M , Willem Theresa , Bredthauer Carl Justus , Buyx Alena
Published: December 2021

Background

Social media recruitment for clinical studies holds the promise of being a cost-effective way of attracting traditionally marginalized populations and promoting patient engagement with researchers and a particular study. However, using social media for recruiting clinical study participants also poses a range of ethical issues.

Objective

This study aims to provide a comprehensive overview of the ethical benefits and risks to be considered for social media recruitment in clinical studies and develop practical recommendations on how to implement these considerations.

Methods

On the basis of established principles of clinical ethics and research ethics, we reviewed the conceptual and empirical literature for ethical benefits and challenges related to social media recruitment. From these, we derived a conceptual framework to evaluate the eligibility of social media use for recruitment for a specific clinical study.

Results

We identified three eligibility criteria for social media recruitment for clinical studies: information and consent, risks for target groups, and recruitment effectiveness. These criteria can be used to evaluate the implementation of a social media recruitment strategy at its planning stage. We have discussed the practical implications of these criteria for researchers.

Conclusions

The ethical challenges related to social media recruitment are context sensitive. Therefore, social media recruitment should be planned rigorously, taking into account the target group, the appropriateness of social media as a recruitment channel, and the resources available to execute the strategy.

Authors: Nwosu Amara Callistus , McGlinchey Tamsin , Sanders Justin , Stanley Sarah , Palfrey Jennifer , Lubbers Patrick , Chapman Laura , Finucane Anne , Mason Stephen
Published: December 2021

Background

Developments in digital health have the potential to transform the delivery of health and social care to help citizens manage their health. Currently, there is a lack of consensus about digital health research priorities in palliative care and a lack of theories about how these technologies might improve care outcomes. Therefore, it is important for health care leaders to identify innovations to ensure that an increasingly frail population has appropriate access to palliative care services. Consequently, it is important to articulate research priorities as the first step in determining how finite resources should be allocated to a field saturated with rapidly developing innovation.

Objective

The aim of this study is to identify research priority areas for digital health in palliative care.

Methods

We selected digital health trends, most relevant to palliative care, from a list of emerging trends reported by a leading institute of quantitative futurists. We conducted 2 rounds of the Delphi questionnaire, followed by a consensus meeting and public engagement workshop to establish a final consensus on research priorities for digital technology in palliative care. We used the views of public representatives to gain their perspectives on the agreed priorities.

Results

A total of 103 experts (representing 11 countries) participated in the first Delphi round. Of the 103 experts, 55 (53.3%) participated in the second round. The final consensus meetings were attended by 10.7% (11/103) of the experts. We identified 16 priority areas, which involved many applications of technologies, including care for patients and caregivers, self-management and reporting of diseases, education and training, communication, care coordination, and research methodology. We summarized the priority areas into eight topics: big data, mobile devices, telehealth and telemedicine, virtual reality, artificial intelligence, smart home, biotechnology, and digital legacy.

Conclusions

The priorities identified in this study represent a wide range of important emerging areas in the fields of digital health, personalized medicine, and data science. Human-centered design and robust governance systems should be considered in future research. It is important that the risks of using these technologies in palliative care are properly addressed to ensure that these tools are used meaningfully, wisely, and safely and do not cause unintentional harm.
Learning and Use of eHealth Among Older Adults Living at Home in Rural and Nonrural Settings: Systematic Review (Preprint)
Authors: Airola Ella
Published: December 2021

BACKGROUND

Care policies emphasize deinstitutionalization and aging in place in response to demographic changes. Different eHealth technologies are one way to achieve this aim. However, there is a need to better understand older adults’ needs for eHealth services, and thus, these health solutions require further exploration.

OBJECTIVE

The purpose of this systematic literature review is to appraise, synthesize, and summarize the literature on older adults’ (aged ≥60 years) eHealth learning and use in real home settings, particularly in rural and remote areas, with a focus on the social and cultural context.

METHODS

A systematic search was conducted in January 2020 using 4 academic databases. The studies by means of qualitative thematic analysis to identify the barriers, enablers, and support practices involved in the domestication process were examined. In addition, we identified the various meanings attached to eHealth technologies for older adults living in rural and remote areas.

RESULTS

In total, 31 empirical studies published between 2010 and 2020 were included in this review. A total of 17 articles included participants from rural and remote areas. The most regularly reported barriers related to older adults’ learning to use and use of eHealth were health-related difficulties, such as cognitive impairment or impaired hearing. The most reported enabler was the support provided for older adults in learning and use of eHealth. Support mainly comprised older adults’ own digital competences, which were distributed with their social network. It was found that eHealth technology is needed for rural and remote areas to facilitate access and reduce logistical barriers to health care services.

CONCLUSIONS

The literature review provided information and practical implications for designers, health care providers, and policy makers. On the basis of these findings, eHealth technologies should be easy to use, and adequate support should be provided to older adults for use.
Boulding’s Psychic Capital: The Linking of Individual and Collective Identities
Authors: Bostock William Walter
Published: December 2021

The purpose of this article is to establish that Kenneth E. Boulding, an economist whose work also encompassed many other disciplines, provided a valuable insight within the study of psychology. Boulding observed that while in an economic unit there is a store of financial capital which is necessary for continued existence, also in human nature there is a need for a reserve of psychic capital that is vital for the mental health of the individual and society. Psychic capital does this by providing a link consisting of positive feelings shared between the individual and the larger grouping. Boulding proposed that a coherent body of thoughts, memories, and emotions may be shared between individual and collective minds as shared psychic capital. Finally, some present-day examples are given whereby the consequences of a loss of psychic capital have been observed with particular emphasis on collective depression and suicide.

Este artículo presenta el análisis del texto del villancico Guineo a 5, Eso rigor e repente escrito por Gaspar Fernandes, maestro de capilla de Puebla, a comienzos del siglo XVII. En dicha composición se pueden percibir ciertos elementos que remiten a la realidad cotidiana y a la visión que la sociedad tenía de los africanos y afrodescendientes en la ciudad de Puebla y la Nueva España. Destaca en este análisis la identificación de elementos de pensamiento espiritual y religioso africano o afrodescendiente (principalmente bantú) en el villancico, probablemente como una referencia a las prácticas de religiosidad católica  afrodescendiente realizadas por esta población. Puebla fue un espacio urbano donde hubo cofradías de negros y músicos afrodescendientes dentro de la capilla musical catedralicia al momento en que se escribió y estrenó este guineo.

Tabasco, con su geografía fragmentada por una intricada red hidrográfica, así como por su bajo porcentaje demográfico, constituía en los primeros siglos del virreinato un paisaje que escapaba al control de las autoridades coloniales. A través del análisis de mapas y fuentes escritas, el presente estudio se propone desarticular las políticas de movilidad que subyacieron a la nueva organización sociopolítica de la región de Tabasco, así como poner en luz posibles prácticas de resistencia al nuevo orden colonial.
Permeability Analysis of Dredged Material and Its Stabilization Using Surkhi/Brick Dust
Authors: Fayaz Misba
Published: December 2021

Abstract: This study presents the permeability and strong relationship of dredged soil stabilized with surkhi/brick dust which is to be used for constructing road embankments. Tests like the unconfined compressive strength test and the falling head permeability test were conducted. The test results showed that as the percentage replacement of surkhi increases, the samples become less permeable. Showing that the surkhi tends to cover up the pore spaces of the soil, causing the water to have fewer passageways. Large amount of sediments are dredged from rivers and lakes as a result of environmental dredging in India. These dredged materials (DM) have poor Geotechnical properties and are normally treated as wastes. On the other Hand, there is a huge demand of sub-grade materials due to the increasing number of highway construction projects in the J&K. Thus, the reuse of the dredged material as sub-grade material may be considered as an Environmental-friendly and economical option. For the stabilization of dredged material various waste materials can be effectively used. brick dust is one such waste product. The surkhi/brick dust is generated from brick kilns. The amount of brick dust produced every year is in the range of 3-4 million ton. This project therefore intends to study the stabilization of dredged material procured from Sindh Nallah having a higher content of alluvial Soil using Surkhi/Brick dust as an additive. Soil stabilization by this means can be utilized on airport pavements, highway pavements, earthen dams and many other situations where sub-soils are not suitable for construction. Keywords: dredged material Sindh Nallah, surkhi, Dredged soil, CBR, UCS, proctor test, porosity, void ratio and permeability

Dietary Fats Are Vital For Human Long-Term Health
Authors: Sumathy.T  , Maheshkumar V.P  , Jaikumar.S
Published: December 2021

Lipids are the major contributors of taste, texture and energy of a diet. Changes in the intake of dietary fats bring about varied serum cholesterol levels as well the other factors that cause risk of chronic diseases. It has been established over years that the risk of CAD and other chronic health problems are not significantly influenced by the dietary saturated fatty acids (SFAs). Many recent researches also reported that the SFAs present in dairy products and coconut oil are very helpful in improving the health of an individual. Even though enhancement of inflammation and augmentation of the chronic ailments by V6 polyunsaturated fatty acids (PUFAs) have been reported widely, the V3 PUFA’s take the other side and act to counter the ill effects. Obesity and other associated health issues arise mainly due to the use of diets rich in carbohydrates instead of saturated fats. The benefits of replacing these carbohydrates and others with alternative nutrients have been well established with known mechanisms which bring down the adverse effects. The quality of fat may bring about chronic degenerative effects in the later stages. The use of fat and its types is shifted towards a pattern of healthy diet wherein the food may include a variety of different fats even at high levels. The present scenario of the researches in public health is mainly centered with the analysis of the association between dietary fat, level and quality, its impact on the risk of chronic diseases and cure. Thus, this review focuses on the need to re-examine the use of dietary fats and their clinical implications.

The use of horses in The History by Georgios Akropolites: a comparison with Historia Romana by Nikephoros Gregoras
Authors: Stamouli Alexia-Foteini
Published: December 2021

The short historiographical text by Georgios Akropolites (1217-1282 CE) covers the period of the Latin conquest of the Byzantine Empire. Due to the important position the author held, and his participation in some of the events narrated, his History is a valuable source. This paper concerns the information Akropolites provides about horses, and compares his work with the part of the historiographical text Historia Romana by Nikephoros Gregoras (c. 1292/1295–1358/1361 CE) that describes the same period. Most of the equestrian references consist of details of the kinds of horses used by various people during wars. Akropolites provides more information about the empire of Nicaea, and delivers further interesting details and descriptions concerning horses.
Interdisciplinary Approaches to the Medieval Warhorse

Published: December 2021

The warhorse is arguably the most characteristic animal of the English Middle Ages. But while the development and military uses of warhorses have been intensively studied by historians, the archaeological evidence is too often dispersed, overlooked or undervalued. Instead, we argue that to fully understand the cultural significance and functional role of the medieval warhorse, a systematic study of the full range of archaeological evidence for warhorses (and horses more generally) from medieval England is necessary. This requires engagement with material evidence at a wide variety of scales — from individual artefacts through to excavated assemblages and landscape-wide distributions — dating between the late Saxon and Tudor period (c. AD 800–1600). We present here a case study of our interdisciplinary engaged research design focusing upon an important English royal stud site at Odiham in Hampshire. This brings together several fields of study, including (zoo)archaeology, history, landscape survey, and material culture studies to produce new understandings about a beast that was an unmistakable symbol of social status and a decisive weapon on the battlefield.
Towards an Economic History of the Horse in the Mediterranean Area during the Middle Ages: What Perspectives?
Authors: Noé Clothilde
Published: December 2021

Studying the economic and non-economic exchanges of the horse in the Mediterranean area during the Middle Ages is a recent phenomenon in history. Indeed, while the trade and circulation of many products in the Mediterranean region, notably sugar, for example, have received substantial attention, equids have remained of surprisingly marginal interest. However, many indicators reveal their historical trading patterns as well as other reasons for the exchange of equids throughout the Mediterranean region. Economic, political, military, and diplomatic histories merge to provide precious information which helps to explain the commercialization of this emblematic animal of the Middle Ages. The aim of this paper is to establish an inventory of historical studies about the exchange of horses in the Mediterranean area, and to contextualise the horse as a real object of historical interest within the topics of exchange and movement of commodities.
Arabians in the Architecture: Historiographic Implications of Misidentification
Authors: Bibby Miriam A.
Published: December 2021

The Arabian, or more correctly, Arab horse, is widely acknowledged to be one of the most influential horse breeds in the world. Enthusiasts of the breed admire its beauty and its quality of endurance. They also frequently claim it has a long and influential history, some suggesting this dates back to the days of the kings of Egypt, if not beyond. It is the historiographical aspect with which this paper intends to engage, arguing that some key examples currently identified as Arab(ian) horses are not Arabs at all. This has created long-standing issues with the literature on the breed and its history, as well as affecting our understanding of the origins of other breeds.

Published: December 2021

Recent global initiatives in ecosystem restoration offer an unprecedented opportunity to improve biodiversity conservation and human health and well-being. Ecosystems form a core component of biodiversity. They provide humans with multiple benefits – a stable climate and breathable air; water, food and materials; and protection from disaster and disease. Ecosystem restoration, as defined by the UN Decade on Ecosystem Restoration, includes a range of management interventions that aim to reduce impacts on and assist in the recovery of ecosystems that have been damaged, degraded or destroyed. This Guide promotes the application of the science of ecosystem risk assessment, which involves measuring the risk of ecosystem collapse, in ecosystem restoration. It explores how the IUCN Red List of Ecosystems and ecosystem restoration can be jointly deployed to reduce risk of ecosystem collapse.

Published: December 2021

We report investigations of the low temperature dc susceptibility and the magnetization on the layered organic superconductor k-(BEDT-TTF)2Cu[N(CN)2]Br near 80 K and the effect of disorder on the superconducting transition temperature Tc. The shielding effect (S) and the critical current density Jc were studied (with H parallel to the c axis of the crystal). Jc can be estimated by analysis of magnetic hysteresis measurement using the Bean model. For each temperature value, we observed two regimes in the critical current density Jc(H). Our results show that the magnetic properties of these compounds depend strongly on the cooling rate. The structural transformation which occurs at the vicinity of 80 K very strongly influences the physics of vortex lattice and the associated magnetic behavior. #organic_superconductor #critical_current #shielding_effect #magnetic_susceptibility #vortex_pinning
On the Bandkeramik on the Lower Vistula River
Authors: Pyzel Joanna
Published: December 2021

The Vistula River is the most important river in Polish history and culture. This paper discusses whether this could influence the hypothesis regarding the crucial role of this river for the Early Neolithic colonization of the Polish lowlands. It presents an overview of the Linear Pottery culture settlement on the lower Vistula River. The main sources of information are broad-scale survey programmes, which provide an impressive number of sites, while the extent of large-scale excavations is very limited. This is an important caveat with respect to statements on similarities and differences in occupation between the lowlands and other regions. Nevertheless, according to the present state of research, the lower Vistula region can be regarded as a remote, but important settlement area of the LBK.

The study was focused on investigating the impact of different washing processes (dark shade, medium shade, light shade) on various properties of denim fabric. Two different types of fabrics with twill and dobby weave constructions were produced from cotton, spandex, and polyester yarn, and different types of washing processes were applied. Dimensional stability, tensile strength, tearing strength, EPI and PPI, weight, colorfastness to rubbing, colorfastness to perspiration (acid and alkaline), and colorfastness to water was investigated and comparisons were made statistically between the before washed sample and after washed sample. It is found that the process result shows better tear and tensile strength in case of dark & medium shade wash than light shade wash. On the other hand, weight and EPI & PPI have shown better result for light wash than other wash. Colorfastness to rubbing, Colorfastness to water, and Colorfastness to perspiration (acid and alkaline medium) are similar. The shrinkage% is higher especially in the weft direction of the fabric for light wash than the dark wash.

Anti-surge control valves are used for the protection of gas compressors by opening to relief sudden pressures (surge) which could damage the compressor internals. It is of great importance that the response of the anti-surge valves to surge detection is swift and within a few seconds since a little delay could cause catastrophic damages to the compressor it is meant to protect. In this paper, a design modification was done on an existing anti-surge valve to improve its response time. The modified system was designed and implemented, installed, and commissioned on a mixed refrigerant compressor. The modified system was tested, and the response performance was recorded. Results obtained showed average percentage improvement of 86% to that of the initial system. Also, the response performance of the modified system was less than 3 seconds as compared to the initial set-up which averages 9 seconds. This is indeed a great improvement in comparison to the initial system.

Published: December 2021

Any single machine rotary component in the process could result in downtime costs. It is necessary to monitor the overall machine health while it is in use. Bearing failure is one of the primary causes of machine breakdown in industry at high and low speeds. A vibration signature evaluation has historically determined misalignments in shafting systems. These misalignments are also responsible for the bearing increase in temperature. The purpose of this work is to undertake a comparative study to obtain the reliability of the effect of the amount of misalignment on bearing by using thermography measurement. An experimental study was performed in this paper to indicate the existence of machine misalignment at an early stage by measuring the bearing temperature using a thermal imaging camera. The effects of load, velocity, and misalignment on the bearings and their temperature increase have been investigated. The test bench's rolling-element bearing is an NTN UCP213-208 pillow block bearing. It has been observed that by tracking the change of temperature in bearings could lead to misalignment detection and the effect of the amount of misalignment on it.

One of the growing concerns in companies in developed countries and in Brazil is to look for new ways to stay in the market, increasing their productivity and improving the quality of their products. The FMEA methodology allows us to avoid, through the analysis of potential failures and proposals for improvement actions, failures in the design of the product or process occur, in order to increase reliability. The reliability of a product is the reflection of the number of failures it presents when subjected to stress tests, thus helping in the detection of problems, determining the time to be offered as a guarantee and helping in the prevention of new failures. The objective of this article is to present a proposal for the application of an FMEA in a white line company, where there is a product with a high failure rate, in which this issue will be analyzed and direct proposals for improvements, seeking to reduce its occurrence in the product.
