Authors: Ferrara Michela , Bertozzi Giuseppe , Zanza Christian , Longhitano Yaroslava , Piccolella Fabio , Lauritano Cristiano Ernesto , Volonnino Gianpietro , Manetti Alice Chiara , Maiese Aniello , La Russa Raffaele
Published: June 2022

Background:

Traumatic brain injury (TBI) can be considered a "silent epidemic", causing
morbidity, disability, and mortality in all age cohorts. Therefore, a greater understanding of the underlying
pathophysiological intricate mechanisms and interactions with other organs and systems is
necessary to intervene not only in the treatment but also in the prevention of complications. In this
complex of reciprocal interactions, the complex brain-gut axis has captured a growing interest.

Aim:

The purpose of this manuscript is to examine and systematize existing evidence regarding the
pathophysiological processes that occur following TBI and the influences exerted on these by the
brain-gut axis.

Methods:

A systematic review of the literature was conducted according to the PRISMA methodology.
On the 8th of October 2021, two independent databases were searched: PubMed and Scopus. Following
the inclusion and exclusion criteria selected, 24 (12 from PubMed and 12 from Scopus) eligible
manuscripts were included in the present review. Moreover, references from the selected articles
were also updated following the criteria mentioned above, yielding 91 included manuscripts.

Results:

Published evidence suggests that the brain and gut are mutually influenced through four
main pathways: microbiota, inflammatory, nervous, and endocrine.

Conclusion:

These pathways are bidirectional and interact with each other. However, the studies
conducted so far mainly involve animals. An autopsy methodological approach to corpses affected by
traumatic brain injury or intestinal pathology could represent the keystone for future studies to clarify
the complex pathophysiological processes underlying the interaction between these two main systems.

Published: June 2022

Osteoporosis is a systemic disease in which bone mass decreases, leading to an increased risk of bone fragility and fracture. The occurrence of osteoporosis is believed to be related to the disruption of the differentiation of mesenchymal stem cells into osteoblasts and adipocytes. N6-adenylate methylation (m6A) modification is the most common type of chemical RNA modification and refers to a methylation modification formed by the nitrogen atom at position 6 of adenine (A), which is catalyzed by a methyltransferase. The main roles of m6A are the post-transcriptional level regulation of the stability, localization, transportation, splicing, and translation of RNA; these are key elements of various biological activities, including osteoporosis and the differentiation of mesenchymal stem cells into osteoblasts and adipocytes. The main focus of this review is the role of m6A in these two biological processes.
Foresee Novel Targets for Alzheimer’s Disease by Investigating
Repurposed Drugs
Authors: Agarwal Kritie , Katare Deepshikha Pande , Jakhmola-Mani Ruchi
Published: June 2022

Background:

Alzheimer’s Disease (AD) is the most rampant neurodegenerative disorder
which has caused havoc worldwide. More than a century has passed since the first case of AD was reported,
but still, no stable treatment is known to humanity. The available medications only provide
temporary relief and are not a cure for the disease. The hunt for advanced techniques in drug development
has paved the way for drug repurposing, i.e., repositioning or reutilizing drugs as an innovative
approach.

Methodology:

Several drugs which were repurposed for AD were collected by following PRISMA
2020 systemic review. Databases like PubMed, ScienceDirect, JSTOR, and SciELO were used for data
extraction. Further, the Drugbank database was used to download all the identified drugs. Later, the
Swiss Target Prediction tool was used to identify protein receptors for these drugs and the biological
pathway followed by them.

Results:

Drugs like Zileuton, Salbutamol, Baricitinib, Carmustine, Paclitaxel, and Nilotinib were observed
to be involved in regulation of neurotransmitters. Similarly, Metformin, Liraglutide, UDCA,
and Bexarotene are involved in protein kinase cascades which also is one of the prime processes in
metabolic disorders like AD. Furthermore, drugs like Rosiglitazone, Pioglitazone, and Lonafarnib are
involved in interleukin-3 biosynthetic processes, which is again one of the most important processes
studied in AD treatment.

Conclusion:

The study concluded that the reviewed drugs that follow similar biological and molecular
processes could be repurposed for AD if chosen judiciously with current medications and thus, drug
repurposing is a promising approach that can be utilized to find a cure for AD within a brief time and
fewer resources compared to de novo drug synthesis. Although certain loopholes still need to be
worked upon, the technique has great prospects. Furthermore, in silico methods can be utilized to justify
the findings and identify the best drug candidate.
A Potential Strategy for Treating Parkinson's Disease Through Intranasal
Nanoemulsions
Authors: Shirsath Krushna , Agrawal Yogeeta O.
Published: June 2022

Intranasal delivery has great potential to cross the blood-brain barrier and deliver the drug
molecule into the central nervous system faster than the traditional methods. The olfactory neuronal
and trigeminal pathways both are involved in intranasal delivery. The nano-technology is an innovative
strategy for the nose to brain delivery. The mucoadhesive nanoemulsion formulation is a modified
technology that increases the duration of drug accumulation and provides prolonged delivery at a targeted
site. The nanoemulsion formulation oil, surfactant, and co-surfactant components maintain lower
surface tension and particle coalescence. The globule dimension and zeta potential are affected in
brain targeting. The globule size of the innovative formulation should be <200 nm for drug permeation
because, in humans, the average axon magnitude ranges from around 100 to 700 nm. Furthermore,
modified technology of nanoemulsions like nanogel and nanoemulsion in-situ gel provide a
great advantage to cure neurodegenerative disorders. Therefore, focusing on the innovative pharmaceutical
approaches of nanoemulsion in intranasal drug delivery, the current review provides insight
into the applications of nanoemulsion in neurodegenerative disorders like Parkinson's disease, which
are due to the depletion of dopamine in substania nigra resulting in cardinal motor activity bradykinesia
and tremors. The review also touches upon the pathways for intranasal delivery of nanoemulsion,
the pathogenesis of Parkinson's disease, and the future direction of the research on intranasal
nanoemulsion.
Proposing Cubic-Grid System as a New Structural System for Tall Buildings
Authors: Sheikhi Morteza , Rezagholizadehomran Farideh
Published: June 2022

Background:

Changes in the skyline of cities all over the world show that tall buildings are an interesting solution to accommodating growth more sustainably in today’s urban areas. Stability against lateral loading is the main issue for designing high-rise buildings. Diagrid systems or grid structures are one of these stable systems. For a long time, the only structural pattern used in this system was the triangular modulus (diagrid).

Methods:

In the present study, a new pattern for grid structures was introduced, and its performance was compared with the two previous common patterns (triangular and hexagonal). The new pattern is called the Isometric Cube grid, thanks to its particular shape. The design process was performed based on a simple stiffness criterion presented in the previous research. In order to calculate the stiffness of the structure for the new pattern, two types of existing structural nodes were distinguished, and the results were combined to determine the stiffness of the unit forming the entire grid.

Results and Conclusion:

From the results of analysis, it was found that the optimal angles of diagonal elements were in the range of 50-65 degrees. Although the behavior of the new pattern in terms of shear stiffness was between the two previous patterns (and closer to the hexagonal pattern), the shear stiffness ratio increased from 30° to 65° for cube pattern, while for hexagrid, it decreased over the same range of angles.
The Thermal Time Constant of an Electrothermal Microcantilever Resonator
Authors: Zarog Musaab
Published: June 2022

Background:

The thermal time constant is the core parameter for determining the dynamic response of the electrothermal actuators and the corresponding maximum operational frequency.

Aim:

Since it is necessary to determine how the thermal actuation is taking place within the cantilever, this paper presents two models for the thermal time constant of bimetal microcantilevers. One model was based on the bimetallic effect, and the second was based on temperature gradients in layers

Methods:

In order to investigate and check the validity of the two roposed model, the device was actuated electrothermally and the thermal time response was estimated. A driving voltage was applied to the platinum electrode. The first model is based on the interface thermal resistance between the base and the top electrode layer. The second model assumes that the temperature gradients within the base layer are responsible for thermal actuation.

Results:

The microcantilever was excited electrothermally with a resonance frequency of 1.89 MHz. The bimetallic effect was found to be less able to stimulate the microcantilever at this resonance frequency. Therefore, the conclusion was that thermal actuation occurred as a result of temperature variation within the SiC base layer.

Conclusion:

The results also indicated that temperature variations within one of the two materials in contact may be responsible for thermal actuation, especially if the material has high thermal conductivity.

Authors: Guo You , Feng Wenqing , Zhang Guoyong , Ouyang Yi , Pi Xinyu , He Lifu , Luo Jing , Yi Lingzhi
Published: June 2022

Background:

With the rapid development of power system, oil-immersed transformers are widely used in the substation and distribution system. The faults of oil-immersed transformers are large threat to the power system. Therefore, it is significant that the faults of oil-immersed transformers can be diagnosed accurately.

Objective:

To accurately diagnose the faults of oil-immersed transformers through machine learning methods and swarm intelligent algorithms.

Methods:

To accurately diagnose the faults of oil-immersed transformers, a fault diagnosis method based on T-distributed stochastic neighbor embedding and support vector machine is proposed. The improved beetle antennae search algorithm is used to optimize the parameters of support vector machine. Firstly, the non-coding ratio method is used to obtain nine-dimensional characteristic indices. Secondly, the original nine-dimensional data are reduced to three-dimensional by T-distributed stochastic neighbor embedding. Lastly, the data after dimensionality reduction are used as the input of the support vector machine optimized by improved beetle antennae search algorithm and the fault types of transformers can be diagnosed.

Results:

The accuracy rate is 94.53% and the operation time is about 1.88s. The results indicate that the method proposed by this paper is reasonable.

Conclusion:

The experimental results show that the method proposed by this paper has a high accuracy rate and low operation time. Mixed faults that are difficult to diagnose also can be diagnosed by this paper's method. In the era of big data, there is a lot of data of transformer, so the method proposed in this paper has certain engineering significance.

In 2019, the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) was first reported in Wuhan, China, affecting the population all over the globe. This ongoing pandemic is creating major havoc and has already taken the lives of many people. It has become really difficult to control the spread of the virus because of its high rate of multiplication in the host and transmission. The virus spreads by the means of droplets or direct contact with the infected person, causing pneumonia-like symptoms, such as fever, dry cough, throat pain, and breathlessness. This review presents the indications, mechanism of action, administration, and adverse effects of some antiviral, antibiotic, and immunomodulatory drugs, that are currently employed in the treatment of SARS-CoV-2. It also presents the effects and benefits of drugs on an infected person, when co-administered together.
Νέα Εστία and the Literary Scene in Greece (1967-1974)
Authors: Theologou Chrysa
Published: June 2022

Νέα Εστία (Nea Hestia), one of the most important literary periodicals in Greece, was established in 1927 by Grigorios Xenopoulos and it is still in circulation today. Petros Charis (who was Xenopoulos’s collaborator from the very first years) was the director of Nea Hestia for more than fifty years (from 1935 to 1987) and he contributed both to the formation of the special character of the periodical and to the history of modern Greek literature. This article focuses on the period that starts with the establishment of the military junta (1967) and ends with its fall (1974). The basic goal of the article is the study the role that Nea Hestia played during the abovementioned years. Some of the questions that I try to answer are: what was the contribution of Nea Hestia to the formation of the Greek literary scene?; to what extent did Nea Hestia influence new tendencies in poetry and prose (the so-called literary generation of 1970) produced during the pressing conditions of the military junta?; in what way did the director Petros Charis and his personal aesthetic and political ideology shape Nea Hestia’s character?; taking into consideration the significant role that the periodical played during the previous decades (1930-1960), did it manage to maintain its position during the years 1967-1974? The approach is based on two axes: The first is the literary content of the main corpus of the periodical and the second is the literary reviews that appeared in a special section. Both the authors whose work is selected for publication and the reviewed books reveal the editors’ choices and can be seen as a ‘mirror’ that reflects changes in the literary scene in Greece.
Oeioei you just have to listen : Rock criticism in Hitweek. A categorization model for evaluation domains in rock music.
Authors: None Alex van der Hulst
Published: June 2022

Rock criticism plays an important role in the formation of rock music as a cultural field in the 1960s. Criticism provides legitimization of taste, canonization and consecration. Nevertheless, the arguments and evaluations within rock criticism have been marginally studied, if at all in the Netherlands. Especially when you compare how literary criticism in its turn is studied as part of Dutch literary theory (see among others Van Rees 1985, Janssen 1994, and Van Dijk 2006). Rock criticism is mostly studied in cultural and music sociology. This research focuses on rock criticism as part of a cultural field (Lindberg et al. 2005). Within the humanities, the study of rock criticism offers an opportunity to map out which arguments are used in criticism and how they are applied.
In research into literary criticism, Mooij, Boonstra, Praamstra, and, following them, Op de Beek and Linders, among others, categorize evaluative statements by critics. I will elaborate on their work in the categorisation of evaluative statements by rock critics. In this article, the categorization model of Op de Beek and Linders is applied and adapted to rock criticism. The corpus of this paper is the archive of Hitweek (1965). A Dutch magazine that appears weekly between 1965 and 1969 (in approximately 190 editions) and pays ample attention to Dutch rock music as part of youth culture. Hitweek is the first critical music magazine for rock music in the Netherlands and is therefore important for the formation of the cultural field of rock music in the Netherlands. For this study, the evaluative statements in the reviews of singles and albums by Dutch bands were examined. The statements are categorized and grouped to provide a picture of what criteria the reviewers of Hitweek used and how the model can help determine these criteria.
This article is one of the few studies into evaluation criteria within Dutch rock criticism. For the time being, it is the only research into the evaluation criteria in Hitweek.
Representations of Acoustic Discourse in The Yellow Book Volumes 1, 2, and 3: Walter Sickert's Music Hall Paintings
Authors: Tarantino Christiane
Published: June 2022

The images Aubrey Beardsley chose to have reproduced within the first, second, and third Volumes of The Yellow Book include; The Old Oxford Music Hall from Volume One (April 1894), The Old Bedford and Ada Lundberg from Volume Two (July 1894),Collins’ Music Hall, Islington, and The Lion Comique both from Volume Three (October 1894). By examining Sickert’s aforementioned reproductions chosen by Beardsley, this paper will utilize the politics of acoustic discourse and intermediality to investigate how Sickert's intermedial acoustic representations of Music Hall are reflective of the social, cultural and technological contentious modernist climate of the 1890s; and why the inclusion of the reproduced images within The Yellow Book are relevant to the magazines status as a total work of art. 
‘A monthly album of crazy fancies’: The Arena, ‘cranks’ and radical magazines in the 1890s
Authors: Marin-Lamellet Jean-Louis
Published: June 2022

This article uses Boston reformer Benjamin O. Flower’s magazine The Arena in its first, most militant and successful period, from 1889 to 1896, as a case study to analyze the relationship between political radicalism and the periodical form and to examine the changing and contested definition of ‘radicalism’. It analyzes how Flower’s ambivalent intentions as an editor and a reformer were reflected in the hybrid nature of his magazine. It also examines two ‘cranky’ movements he was associated with: middle-class women’s struggle for emancipation and Populists’ fight against railroad and money monopolies. This paper explores how radicals used print culture to circulate and legitimize the fringe protest movements they thought would regenerate the United States.
‘Spatializing Europe’ – Ethno-Pluralist Approaches through Cultural Transfer in the Revista de Occidente (1923-1936)
Authors: Lemke Duque Carl Antonius
Published: June 2022

This study focuses on the question how Europe was spatialized through cultural transfer in the Revista de Occidente between 1923 and 1936 in Spain. Two complementary discourses will be analysed: Firstly, contributions in cultural history that framed Europe as a world area amongst other, extra-European spaces; secondly, the main ideas and theories that determined a particular European spatial ingredient. While the first discourse focuses on non-European geographical areas as ‘monolithical cultures’, the second discourse stresses the notion of Europe as an ethnopluralist entity. Both complementary discourses will be examined separately by a two-step analysis. As a final conclusion, the present paper highlights the ethno-pluralist character in this process of a spatialization of Europe through cultural transfer.

Girls Girls Girls Girls Girls: The Trans-Atlantic Mass Magazine Culture of the 1920s as a Gendered Affair
Authors: Mayer Ruth
Published: June 2022

The article explores the ways in which illustrated magazines of the Weimar period contribute to a larger gendering of transnational exchange, particularly through image-text doubling and shifts. It takes the Weimar society magazine Uhu as a major reference point, investigating how it modelled itself on American lifestyle and ‘smart’ magazines and made use of the iconic figure of the ‘Girl’ to carve out a spatio-temporal continuum between ‘Amerika’ and Europe. While the Girl is a figure of the stage and screen as much as of the modern magazine, it is in the magazine that this figure comes into her own. The Girl incorporates modernity as a multimodal and multifaceted configuration much like the modern magazine itself. The article argues that the Girl enters the illustrated magazines not only as a subject matter but also as a tool of gendered self-reflection, particularly in the work of female writers, illustrators, and photographers.
In Time: Periodical Theories and Philosophies of History in the Nineteenth and Twentieth Centuries
Authors: Neuffer Moritz
Published: June 2022

Throughout modern history, concepts and metaphors of time have been part of the self-conception and self-marketing of countless periodicals. Concentrating on journals and magazines from the German-speaking countries between around 1800 and around 1968, the article outlines a history of the periodical as a subject and object of philosophies of historical time. The cases examined not only show the affinity between periodical theory and the philosophy of history, but also shed light on the specific roles that have been attributed to periodical publishing in varying conceptions of the modern intellectual public sphere.
Periodicity, Subscription, and Mass Circulation: Mail-Order Book Culture Reconsidered
Authors: Norrick-Rühl Corinna
Published: June 2022

Connections between periodical studies and book history run deep. Building on this existing work, this contribution discusses untapped potential at the cross-section of book studies and periodical studies, especially when considering mass-market periodical and book formats. Several popular magazines, among them Psychology Today and Playboy, created book series and even book clubs, expanding their brands and diversifying their income streams. The article offers a case study of the mass-market book club ‘Reader’s Digest Condensed Books’, launched by the magazine Reader’s Digest in the 1950s. This popular club reached millions of households in the second half of the twentieth century and still continues to play a role in the book industry today with the series ‘Reader’s Digest Select Editions’.
Micromicetos asexuales hallados sobre hojas de Quercus spp. (Fagaceae) en Huixquilucan, Estado de México, México
Authors: Delgado Zúñiga José Pablo , Heredia Gabriela , Rodríguez-Gutiérrez Ibeth
Published: June 2022

Antecedentes y Objetivos: Los micromicetos asexuales (MA) constituyen un grupo diverso y abundante de hongos en la naturaleza. Hasta la fecha, para el Estado de México no se habían realizado estudios sobre estos hongos. El objetivo de esta aportación es proporcionar información sobre la riqueza taxonómica de las especies de MA que habitan en hojas vivas senescentes y muertas de cinco especies de Quercus de un bosque templado en el municipio Huixquilucan, Estado de México, México.Métodos: Durante un año, quincenalmente se cortaron hojas de cinco especies diferentes de encinos vivas senescentes y se recolectaron hojas del suelo. Las muestras se incubaron en cámaras húmedas; la revisión microscópica se efectuó dos veces por semana. La determinación taxonómica se basó en la conidiogénesis y en las características morfométricas de los conidiomas. El material de referencia (preparaciones microscópicas), se depositó en el herbario del Instituto de Ecología, A.C. (XAL) en Xalapa, Veracruz, México. Los nuevos registros para la micobiota de México se ilustran y describen en detalle.Resultados clave: Se identificaron 30 especies de MA, 12 de ellas constituyen nuevos registros para el país y todas lo son para el Estado de México. En las hojas muertas del suelo hubo un mayor número de especies que en las hojas vivas senescentes. Ocho de los taxones identificados no habían sido recolectados desde que fueron descritos como especies nuevas para la ciencia. Trichothecium roseum, Pestalotiopsis maculans y Vermiculariopsiella immersa son micromicetos que están ampliamente distribuidos en las hojas de todas las especies de encinos estudiadas.Conclusiones: La riqueza de MA encontrada en el área de estudio evidencia que las hojas de los Quercus son sustratos que albergan una considerable riqueza fúngica aun desconocida en México. Lo anterior es una importante razón para la conservación de los bosques de Quercus y promover estudios sobre este grupo de micromicetos en nuestro país.
Retrospective and prospective of the Algerian healthcare supply: Some obstacles that have become chronic discomforts
Authors:   Department of Finance Sciences, Faculty of Economics, Business and Management Sciences, Oum El Bouaghi University, Oum El Bouaghi, Algeria, et al. Aissaoui
Published: June 2022

The current paper attempts to analyze the causes, which divert the care structures from their fundamental mission, and to evoke the consequences of this situation on the main actors who make up the Algerian health system, to try to prescribe the solutions likely to improve the quality of health care in this country. Although free healthcare has been decreed since 1973 to overcome the financial obstacles, and despite the efforts of successive governments to dismantle the geographical obstacles, unfortunately, the organizational obstacles have not found effective and lasting solutions until now; the majority of experts have pointed out this type of obstacle since the outbreak of the COVID-19 pandemic. This article highlights the growth of national and international scientific research; on the conditions that can improve the quality of health care provision. Nevertheless, current work barely addresses organizational shortcomings, particularly in the unique context of a health system that provides free health care. Through an analysis of the Algerian context, this article proposes avenues of research for the organizational obstacles that can hinder the performance of the health care system, which can constitute future empirical studies. The results of the study indicate that there is a great disparity between the regions ranging from the North to the South of the country in terms of health coverage (hospital beds, specialized care, medical personnel, etc.); a flagrant lack of operational medical equipment, and a shortage of medicines for hospital use; despite the good results recorded over the past three decades, expenditure continues to increase steadily; the private sector does not play its role as a complement to the public sector, it improvises as best it can to provide less risky lucrative care; and the application of obsolete legislation that governs a sick hospital.
Acceptability of an mHealth Family Self-management Intervention (myFAMI) for Pediatric Transplantation Families: Qualitative Focus
Authors: Lerret Stacee Marie , Flynn Erin , White-Traut Rosemary , Alonso Estella , Mavis Alisha M , Jensen M Kyle , Peterson Caitlin G , Schiffman Rachel
Published: June 2022

Background

Around 1800 pediatric transplantations were performed in 2021, which is approximately 5% of the annual rate of solid organ transplantations carried out in the United States. Effective family self-management in the transition from hospital to home-based recovery promotes successful outcomes of transplantation. The use of mHealth to deliver self-management interventions is a strategy that can be used to support family self-management for transplantation recipients and their families.

Objective

The study aims to evaluate the acceptability of an mHealth intervention (myFAMI) that combined use of a smartphone app with triggered nurse communication with family members of pediatric transplantation recipients.

Methods

This is a secondary analysis of qualitative data from family members who received the myFAMI intervention within a larger randomized controlled trial. Eligible participants used the app in the 30-day time frame after discharge and participated in a 30-day postdischarge telephone interview. Content analysis was used to generate themes.

Results

A total of 4 key themes were identified: (1) general acceptance, (2) positive interactions, (3) home management after hospital discharge, and (4) opportunities for improvement.

Conclusions

Acceptability of the intervention was high. Family members rated the smartphone application as easy to use. myFAMI allowed the opportunity for families to feel connected to and engage with the medical team while in their home environment. Family members valued and appreciated ongoing support and education specifically in this first 30 days after their child’s hospital discharge and many felt it contributed positively to the management of their child’s medical needs at home. Family members provided recommendations for future refinement of the app and some suggested that a longer follow-up period would be beneficial. The development and refinement of mHealth care delivery strategies hold potential for improving outcomes for solid organ transplantation patients and their families and as a model to consider in other chronic illness populations.

Impact of education, food restriction, and body image on postpartum nutrientBackground: The level of nutritional consumption of postpartum mothers increases for the need for tissue repair and the breastfeeding process, but in practice, there are still many postpartum mothers who have not met the recommended level of nutritional consumption due to several factors, including education level, dietary restriction, and body image. Objective: This research seeks to determine the relationship between education level, dietary restriction culture, and body image with the level of macro nutritional consumption. Method: This research implemented an observational analytic method with a cross-sectional design. The sample size was 40 mothers selected using the convenience sampling technique, with data obtained through face-to-face, Google form, and telephone. The independent variables are education level, dietary restriction culture, and body image. The dependent variable is macro nutritional consumption, including energy, carbohydrates, protein, and fat. The instruments used were the Body Shape Questionnaire (BSQ) to measure body image, the food recall questionnaire, and the food frequency questionnaire (FFQ) to measure nutritional consumption. Data analysis was performed using the Chi-Square test. Results: The results showed that most of the mothers had not met their energy, carbohydrate, and protein needs but were able to consume fat that exceeded the nutritional adequacy rate. The analysis results showed no relationship between education level, dietary restriction culture, and body image with consumption of macronutrients (p>0.05). \Conclusion: There is no relationship between education level, dietary restriction culture, body image with the level of nutritional consumption of energy, carbohydrate, protein, and fat.

Diet quality and glycemic control in adults with type two diabetes mellitusBackground: As assessed by Alternate Healthy Eating Index (AHEI), diet quality is correlated with glycemic control through its effect on glucose-insulin homeostasis. Studies are evaluating the diet quality index in Indonesia, especially its relation to glycemic control in those with type 2 diabetes mellitus (T2DM), are lacking. Objective: To analyze the association between diet quality and glycemic control T2DM in adults. Methods: This research was a cross-sectional study using data from "Cohort study of non-communicable disease risk factors" in 2016 by the Indonesia Ministry of Health. Hundred and five (105) subjects diagnosed with T2DM, aged 25-65, were recruited in this study. A 24-hour dietary recall was collected, and a diet quality index referred to the USA adapted AHEI-2010 was assessed. The portion of food components was modified based on the Indonesian Dietary Guidelines. Glycemic control was evaluated according to fasting blood glucose (FBG) and 2-hours-post-75-g glucose load (2h-PG). Spearman correlation test was applied in this analysis. Results: A mean age of subjects was 51 years, and 77.1% out of 105 subjects were women. Mean value of FBG 123.5 and 2h-PG 228.9 mg/dL. The total score of AHEI was 53.8. There was not a significant correlation between the total score of AHEI with FBG (r= -0.079) and 2h-PG (r= -0.069) (p>0.05). However, there was a significant association between the fruits score and 2h-PG (r= -0.224) (p<0.05). Most of the subjects consumed fruits containing low-moderate fructose, such as bananas, oranges, papayas. Conclusions: In T2DM, there was no significant association between the total score of current diet quality and poor glycemic control, except for the fruits component.

Nutrition education using booklet media with and without counseling on parental knowledge, amount and frequency of consumption of vegetables and fruits of preschool children in urban areasBackground: Consumption of vegetables and fruit in preschool children in Indonesia is still less than recommended. Nutrition education through booklets and counseling media will clarify information and understanding of parents about the importance of consuming vegetables and fruit in preschool children, resulting in parental feeding behavior to increase the amount and frequency of consumption of vegetables and fruits in preschool children. Purpose: This study aims to determine the effect of nutrition education using booklet media with counseling and without counseling on parental knowledge, amount, and frequency of consumption of vegetables and fruits of preschool children in urban areas. Methods: This type of research was a quasi-experimental research design with pre and post-test with the control group. The selection of respondents used purposive sampling to select the sub-districts that had the percentage of excess nutrition in Yogyakarta, namely the Danurejan District, and simple random sampling to choose children and preschools (kindergarten). The number of respondents was 56 people consisting of 28 experimental and 28 controls from 4 kindergartens. Nutrition education in the experimental group gave booklets and counseling, once for 30-60 minutes and at each respondent's home. The control group was only assigned a booklet without counseling. The instruments used consisted of booklets, knowledge questionnaires, and SQ-FFQ. The statistical tests used were paired t-test, Wilcoxon, Mann Whitney, independent t-test, and Pearson. Results: This study showed increased parental knowledge before and after nutrition education in the experimental group (p<0.05). In addition, the amount and frequency of consumption of vegetables and fruits of preschool children in the experimental group increased between before and after being given nutrition education (p<0.05). Knowledge, amount, and frequency of consumption of vegetables and fruit also showed differences between the experimental and control groups (p<0.05). Conclusions: Nutrition education using booklets and counseling media affects parents' knowledge and the amount and frequency of consuming vegetables and fruit in preschool children compared to using only booklets without counseling.

Det Norske Veritas (DNV) yang merupakan sebuah institusi sertifikasi independen, memberikan formulasi untuk menghitung pengurangan kapasitas tali baja berdasarkan rasio diameter pembengkokan dan diameter tali baja, D/d. Pengurangan kapasitas dalam hal ini adalah rasio terhadap kapasitas normal tali baja dalam kondisi aksial tarik. Penelitian ini dilakukan untuk mengetahui korelasi antara kondisi pembengkokan paksa dengan pengurangan kapasitas tali baja, mengetahui selisih antara hasil simulasi dengan formulasi DNV, serta mengetahui parameter yang berkontribusi terhadap pengurangan kapasitas tali baja. Penelitian dilakukan dengan metode simulasi elemen hingga. Dimulai dengan pemodelan kasus aksial tarik dengan variasi sudut lilitan, dilanjutkan dengan validasi terhadap hasil eksperimen dari literatur. Model dengan error minimum selanjutnya digunakan dalam simulasi pembengkokan paksa. Pengurangan kapasitas tali baja yang terjadi dibandingkan dengan hasil formulasi DNV. Hasil penelitian menunjukan semakin kecil nilai D/d pengurangan kapasitas yang terjadi semakin besar. Perbandingan dengan formulasi DNV menunjukan kesesuaian yang baik pada nilai D/d yang besar tetapi menurun pada nilai D/d yang semakin kecil dimana selisih yang dihasilkan semakin meningkat. Hasil simulasi juga menunjukan bahwa kekakuan material sangat mempengaruhi pengurangan kapasitas tali baja di bawah pengaruh pembengkokan paksa.

Media filtrasi merupakan material yang pada saat kondisi operasi sebuah filter memiliki sifat mampu alir terhadap fluida tertentu dan juga memiliki sifat tidak mampu alir terhadat zat-zat pengotor tertentu. Filter tipe Deep-bed filtration memiliki media filtrasi berbentuk padatan granular seperti pasir maupun berupa lapisan serat alam, serat sintetis ataupun serat metal yang dipadatkan. Serat yang digunakan sebagai media filtrasi Deep-bed filtration bekerja dengan prinsip saat fluida mengalir melalui filter maka zat-zat partikulat pengotor tertahan dan terkumpul di sela-sela rongga pori-pori yang terbentuk diantara sekumpulan serat media filtrasi. Jumlah serat yang digunakan per satuan volume atau densitas media filtrasi menentukan nilai tahanan alir atau permeabilitas sebuah media filtrasi. Penelitian ini difokuskan dalam melihat karakteristik permeabilitas media filtrasi serat sabut kelapa berdasarkan jumlah kerapatan serat yang digunakan. Karakteristik permeabilitas media filtrasi sangat berpengaruh terhadap efisiensi aliran fluida dalam aplikasi filter pasir sumur minyak bumi. Karakteristik permeabilitas serat sabut kelapa diukur dengan cara membuat core spesimen uji diameter 3,8 cm, panjang 7 cm dan variasi massa serat sabut kelapa spesimen uji 7,5; 10; 15; 17,5 dan 20 gram. Kemudian masing-masing spesimen uji core diukur nilai permeabilitasnya menggunakan alat Permeability Meter AFS200. Hasil penelitian menunjukkan bahwa nilai permeabilitas serat sabut kelapa menurun seiring bertambahnya massa serat sabut kelapa yang digunakan untuk membuat core spesimen uji. Nilai permeabilitas paling rendah 8508 miliDarcy diperoleh dari spesimen uji dengan massa sabut 20 gram dan nilai permeabilitas paling tinggi 19.790 miliDarcy dihasilkan dari spesimen uji dengan massa sabut 7,5 gram.

Nowadays, the need for linear actuator as a component of a hospital bed is increasing due to the growing needs of electric bed. The function of this component is to adjust the form of the bed for the patient’s comfort. However, the producers of the local hospital bed mostly rely on foreign products. To reduce the production cost, an effort was made to design a low cost yet functional electric linear actuator. The actuator using basic components, consists of a DC motor, transmission, and screw mechanism. Stainless steel pipe with outer diameter of 26 mm was used for the body of the actuator. The performance of the actuator was tested by applying gradual loading with variations on the stroke. It was shown that the the actuator works well in varying loads from 0 to 150 kg with varying stroke from 0 to 19 cm.

Pada industri minyak dan gas bumi, selain digunakan dalam proses penyambungan pipa minyak dan gas bumi, pengelasan juga digunakan untuk perbaikan penguatan dinding pipa ketika terjadi penurunan ketebalan, salah satunya dengan metode perbaikan yang dilakukan adalah weld-deposition. Namun demikian, metode ini memiliki risiko kegagalan berupa burn-through dan hydrogen cracking. Pada penelitian ini, dilakukan pengelasan deposisi pada pipa API 5L X52 dengan nominal diameter 4 inchi (101.6 mm) dan sisa ketebalan dinding pipa 4 mm yang dialiri air dengan kecepatan 15,4 liter per menit (lpm). Dari hasil pengujian ini, akan didapatkan nilai temperatur pada dinding pipa dan waktu yang diperlukan untuk terjadi penurunan suhu dari 800oC ke 500oC (Δt8/5). Pengujian menggunakan beberapa nilai heat input yang merupakan manifestasi dari kuat arus I antara 160 – 200 A, voltase V sekitar 24 – 30 V, dan kecepatan pengelasan v bervariasi dengan interval 2 – 10 mm/s yang menghasilkan heat input pada rentang 0,3031 kJ/mm sampai dengan 1,6907 kJ/mm, sedangkan parameter lain diasumsikan tetap. Penelitian ini menghasilkan rekomendasi pengelasan dengan metode weld-deposition pada pipa in-service dengan mengaplikasikan heat input pada rentang 0,5388 kJ/mm sampai dengan 1,3526 kJ/mm untuk debit alir fluida air 15,4 lpm untuk menghindari potensi timbulnya hydrogen crack dan burn-through. Burn-through sendiri terjadi pada heat input 1,6907 kJ/mm pada kecepatan pengelasan 2 mm/s.
