La traducción en el marco del desexilio: acercamiento a Nordan-Comunidad y Vintén Editor.
Authors:   Universidad de la República, Torres Rippa Cecilia
Published: January 2025

Durante la etapa final de la dictadura y los primeros años de la democracia diversas propuestas editoriales surgieron en el Uruguay y en el exterior como modo de revitalizar el campo local, mermado por crisis que supuso para el sector la represión. En estecontexto, nacen dos editoriales en Suecia en los ochenta: Nordan-Comunidad (1980-2019) y Vintén Editor (1980/2-2006). Estas desarrollarían —primero desde Estocolmo y Växjö (respectivamente), luego en Montevideo—una intensa labor, en la cual destacan las primeras traducciones de sus catálogos, publicadas con el doble objetivo de colaborar en el desexiliode quienes retornaban al país y para plantear, desde lo literario, un espacio de reflexión respecto del fascismo y de las experiencias de los presos políticos. Es así que en 1988 Nordan-Comunidad publica en Montevideola primera traducción al español de Kalocaínade Karin Boye (a cargo de Anahy Cabrera y Ana Luisa Valdés) y en 1990 Vintén edita, también en Montevideo, Acerca de la libertadde Ingemar Moberg(traducido por Anahy Cabrera). Enmarcados en líneas editoriales que buscan fortalecer la democracia mediante la puesta en circulación de obras literarias y de ciencias sociales en un ambiente de desarrollo cultural, estos textos ponen en diálogo (no solamente a través de sus traducciones, sino también mediante los paratextos que acercan la obra al lector local) dos experiencias: la de la amenaza nazi en la Suecia de los años cuarenta y la de las dictaduras del Cono Sur de los setenta. Abordaré, entonces, desde los estudios del libro, la lectura y la edición, los intercambios entre dos sistemas literarios lejanos hasta el momento y el rol de las editoriales como mediadoras entre culturas a través de los paratextos en la traducción.
ТЕРИТОРІАЛЬНА ОРГАНІЗАЦІЯ РИТЕЙЛЕРСЬКИХ МЕРЕЖ УКРАЇНИ В УМОВАХ ВІЙНИ (НА ПРИКЛАДІ ТОВ «СІЛЬПО-ФУД»)
Authors: Бондар В.В.
Published: January 2025

Повномасштабне вторгнення росії в Україну на початку 2022 р. суттєво вплинуло на роботу найбільших мереж вітчизняного продуктового ритейлу, торговельні об’єкти яких змушені були змінити місце своєї локації, особливо у південно-східних регіонах країни. Метою дослідження є аналіз трансформаційних процесів розвитку територіальної організації регіональної мережі супермаркетів ТОВ «Сільпо-фуд» як одного з провідних food-операторів країни в умовах повномасштабної військової інтервенції країни-агресора. Для досягнення поставленої мети автором узагальнено основні тенденції та виклики для функціонування об’єктів даної мережі у складних умовах соціально-економічного розвитку, визначено потенційно можливі загальні обсяги фінансових збитків для втрачених супермаркетів оператора на тимчасово окупованих територіях Донбасу й Придніпров’я та виявлено кількісне представництво нових відкритих торговельних локацій мережі у регіональному розрізі протягом 2022–2023 рр. З’ясовано, що з квітня по грудень 2022 р. мережа «Сільпо» відкрила вісім нових супермаркетів загальною торговельною площею 10,6 тис м2, переважно в регіональних і субрегіональних центрах Київської та Львівської областей. У 2023 р. оператор продовжив активну регіональну експансію, відкривши ще 11 нових торгових точок (15,2 тис м2) у західних та центральних областях, збільшивши їх кількісне представництво у мережі до 312 супермаркетів. При цьому здійснені нами розрахунки показали, що загальна торговельна площа для втрачених супермаркетів мережі на вище зазначених тимчасово окупованих територіях становила близько 25,2 тис м2, а потенційно можливий загальний обсяг отриманого товарообороту цими підприємствами в 2022 р. за умови їхнього звичного режиму роботи у мирний час становив би не менше ніж 3,7 млрд грн.
СТАЛА РЕГЕНЕРАЦІЯ ЗАТОПЛЕНИХ КАР’ЄРІВ ЯК ПЕРЕДУМОВА СТВОРЕННЯ ТУРИСТИЧНО-РЕКРЕАЦІЙНИХ КОМПЛЕКСІВ (КЕЙС КРИВОГО РОГУ)

У статті досліджується важлива багатоаспектна проблема, вірне розв’язання якої матимете значний позитивний вплив на розвиток рекреації та туризму у Кривому Розі – потужному промисловому центрі України та являтиме собою вдалий приклад регенерації відпрацьованих кар’єрних ландшафтів. Сьогодні ключовим питанням не тільки у Кривому Розі є питання рекреації місцевого населення та гостей міста, оскільки відпочинок на узбережжях морів став ризикованим та майже неможливим, пляжі в межах міста котрий рік поспіль не отримують дозволу на організацію місць купання, а бази відпочинку у передмісті мають досить обмежений ресурс, і зазвичай співвідношення «якість – ціна» не є адекватним. З іншого боку, у місті є досить велика кількість відпрацьованих кар’єрів, які заповнилися водою і не один рік використовуються як місця стихійної рекреації, що теж є небезпечним. Автори пропонують знайти рішення даної проблеми, поступово вивчаючи світовий досвід регенерації та перепрофілювання бувших у використанні кар’єрів, використовуючи власний досвід організації та проведення екскурсій і турів до міста, де у програмі обов’язковим є відвідування як діючих залізорудних кар’єрів, так і напрочуд естетично привабливих кар’єрних озер. У статті здійснено порівняльний аналіз придатності кар’єрів Криворіжжя (Карачунівського, Кресівського та Візирки) для здійснення рекреаційно-туристичної діяльності та визначено як найбільш придатний для регенерації Кресівський кар’єр. Для створення проєкту регенерації даного об’єкта автори дібрали Business Model Canvas і обґрунтували «Бізнес-модель креативного туризму «Парк «Зелена хвиля» Екопригоди у затопленому гранітному кар’єрі». Удалий вибір моделі регенерації та впровадження сталих практик дадуть змогу зменшити ризики функціонування таких відпрацьованих кар’єрів, створити цінні екосистеми та зробити свій внесок у збалансований розвиток громади та більш стійке екологічно чисте майбутнє.

Dönüşümün Kimlik ve Fonksiyon Bağlamında Okunması: Kiliseden Camiye İstanbul
Authors: Tokat Esra
Published: January 2025

Bu çalışmada, İstanbul’un fetih sonrası yaşadığı dönüşüm; değişen toplumsal yapı ve buna bağlı olarak dönüştürülen eserler üzerinden okunmuş, aynı amaca hizmet etmek üzere dönüşüme uğramış farklı plan tiplerindeki yapıların yeni işlevleri için uygunlukları tartışılmıştır. Yeniden işlevlendirme bağlamında dini yapıların seçilmesinin nedeni, hem İstanbul’da birçok somut ve erişilebilir/gözlemlenebilir örneğin bulunması hem de yeniden işlevlendirme konusunu, ihtiyaçlar bağlamında tartışmaya fırsat sunmasıdır. Çalışmada, camiye dönüştürülmüş farklı plan tiplerine sahip beş adet kilise yapısı seçilerek yerinde gözlem ve literatür araştırması yöntemleriyle incelenmiştir. Dönüşüm süreçlerini daha iyi tahlil edebilmek adına, Bizans’ın muhtelif dönemlerinde inşa edilmiş ve özgün durumlarında Bizans mimarlığı süresince ortaya konmuş farklı plan tiplerine sahip yapılara yer verilmesine dikkat edilmiştir. Yapıların sadece ilk inşa tarihlerinin esas alınması, dönüşüm sürecindeki yaklaşımların tam olarak analizini engelleyeceğinden, Osmanlının dönüşüm odaklı iki farklı zaman diliminde müdahale edilmiş yapılara özellikle yer verilmiştir. Bunlar, Bizans mimarlığı süresince değişik dönemlerde inşa edilmiş ve fethin hemen ardından gelen ilk dalga dönüşüm faaliyetleri ile ikinci dalga olarak nitelendirebileceğimiz II. Bayezid dönemi dönüşüm hareketlerine konu olan kilise yapılarıdır. Belirlenen yapılar öncelikle konumları ve dönüşüm gerekçeleri çerçevesinde incelenerek ihtiyacın yeni işlev üzerindeki etkisi tartışılmıştır. Daha sonra yapılara yeni işlevleri için duyulan ihtiyaçlar doğrultusunda yapılan müdahaleler ortaya konmuştur. Böylece makalenin ana konusu olan ‘farklı plan tiplerindeki yapıların dönüşüm gerekçeleri ve yeni işlevleri için uygunluğu’ irdelenmiştir.

Published: January 2025

Introduction: Various factors contribute to knowledge, attitudes, and practices toward family planning practices in rural Bangladesh. Unfortunately, studies on the knowledge, attitude, and practices of Bangladeshi nationals in a rural setting are not sufficient. Objective: This study aimed to #nd out people’s knowledge, attitudes, and practices for getting family planning services in rural areas of Bangladesh. Materials and methods: A qualitative descriptive study was employed to follow a semi-structured questionnaire format. A total of 36 participants were interviewed from an upazila. Relevant works of literature were reviewed to enhance our understanding of the issue in question. The questionnaires were pretested before finalization. Results: All of the 36 participants were concerned regarding family planning but 16 (44.44%) of them were currently practicing, and 8 (2.22%) of them never used any of them in their conjugal life. Of all users, the Pill was the most favorite method 24 (82.76%). Condom 2 (6.9%), Injectable 1 (3.45%), Vasectomy 1 (3.45%), and Withdrawal 1 (3.45%) methods were common in the community. Though interested in using the methods, 32 (88.89%) participants didn’t know the benefits and side effects of using them. The majority of 30 (83.33%) of them got information regarding family planning from family members, and the rest of them were from media 6 (16.67%), health workers 5 (13.89%), and neighbors 8 (22.22%). Of those who used, 23 (85.18%) of them collected family planning materials from local pharmacies and the rest of them got them from hospitals 6 (22.22%) or, other #eld workers 3 (11.11%). Though their conjugal life varied but majority of them 23 (63.88%) had 1 or, 2 children. The majority of the participants 12 (33.33%) were between 14-28 years of age group, 34 (94.44%) of them were housewives and most of them had completed secondary level 25 (69.44%). Conclusion: We can have regular meetings in the community with users and service providers to make our knowledge and practices better. People of all ages, genders, and different incomes need to be involved to support services that are based on solid evidence. We need to teach and talk a lot about ways to plan your family and the services available for it.

Authors: Pervez Md Imtiaz , Rahman Ridwana , Khan Masuma , Sonia Zannatul Ferdous , Ahmed A S M Nawshad Uddin
Published: January 2025

Introduction: Very low birth weight (VLBW) babies are at increased risk from a wide range of hazards resulting from immaturity of structure and functions of many organs, which may cause death or permanent damage. Objective: The objective of this study was to evaluate immediate outcomes in VLBW babies. Materials and Methods: This hospital-based prospective cohort study was conducted in the Department of Paediatrics, Kumudini Women’s Medical College and Hospital, Mirzapur, Tangail from August 2008 to July 2009. At enrollment VLBW babies (birth weight <1500 grams) were assessed for gestational age and weight. Patients were followed up daily till discharge or death. The outcome in terms of survival till discharge was recorded. Informed verbal consent from the caregiver was taken before enrolment. Results: A total of 60 VLBW neonates were enrolled in the study. Eight (13.3%) neonates had weights below 1000 grams and 52 (86.7%) had 1000-1499 grams. Five (8.3%) neonates had gestational age <28 weeks, 44 (73.3%) were 29-32 weeks, and 11(18.3%) were 33-36 weeks. Maternal age, place, and mode of delivery were significant contributory factors. In the present study, 35(59%) of VLBW babies expired; 100% of babies died below 1000 grams. Neonatal mortality showed an inverse relationship with birth weight and gestational age. Conclusion: Proper antenatal care should be encouraged throughout the country to prevent the neonatal mortality associated with VLBW infants. Management of labor is important and facilities for the management of high-risk pregnancy should be made available widely. Immediate management of newborns after birth can prevent the worst hospital outcomes in our country.

Background: Cell phone is very important and wonderful communicative tools used by all age group people especially young generation. Extra sense of security and safety is probably one of the main reasons parents even consider getting a younger child a cell phone. This study was designed to assess perception of the people about young generations indulge in cell phone use. Methods: This descriptive cross-sectional study was conducted among 725 respondents selected purposively from areas of Dhaka North City and Dhaka South City Corporation. Relevant data were collected through face-to-face interview with the help of semi-structured questionnaire. Results: Among the total 725 respondents 63.0% were male and the rest 37.0% were female. In Bangladesh the sex ratio is 0.98 (980 males per 1,000 females). Regarding education, it was seen that most were literate (97.2%) having education from non-formal to graduation and above. Majority of the respondents (60.6%) were graduates and above and 20.8% passed higher secondary education. The literacy rate of Bangladesh in the urban area is 81.28 % while in rural area it is 71.56. The rate is higher among the male population which is 76.56%, while among female population it is 72.82%. Adult literacy rate is the percentage of people ages 15 and above whom can both read and write with understanding a short simple statement about their everyday life. One fifth (20.6%) of the respondents were service holders, 17.1% were students, 15.7% were doctors, and 14.1% were businessmen. Conclusion: Cell phone becomes most popular in adolescence students for special feature like social networking and gaming service. Although cell phone is useful and convenient, adolescences are dependent on cell phone more and more for unnecessary communication. Considering its negative impact of cell phone over use on physical and psychosocial health, public health programs should develop preventive strategies.

Published: January 2025

Background: Prescriptions are one of the prescribing standards to promote the rational use of drugs. To provide a corrective message to prescribers, it is important to evaluate prescription patterns and identify unreasonable prescribing practices. Keeping these facts in consideration the present study was planned to assess the prescription pattern using WHO prescribing indicators. Methods: The cross-sectional study was conducted at outpatient department of Dhaka Medical College Hospital and Sir Salimullah Medical College Mitford Hospital, Dhaka from January to December, 2022. A systematic random sampling technique was used to select prescriptions and data were collected by observation check list. Data were analyzed by statistical software- SPSS 23 version. Ethical issues were maintained strictly. Results: Around 296 prescriptions were analyzed. Average number of drugs per prescription was 3.5 (optimal value 1.6–1.8). About 1043 drugs were prescribed, from which 24.73% were with their generic name (optimal value 100%), antibiotics and injections were prescribed 57% (optimal value 20.0–26.8%) and 3.37% (optimal value 13.4–24.1%) respectively. About 32.7% drugs were prescribed from the Essential Drug List. During the study period, anti-ulcerant and NSAIDs were highest prescribed drug (69.3%) followed by antibiotics (57.1%). Conclusion: The study result revealed that average number of drugs per encounter, generic formatting, antibiotic prescribing, and the use of Essential Drug List (EDL) of the hospital to prescribe drugs out of the recommended values. Periodic training and initiating the performance evaluation for doctors are effective ways for improving prescription quality. There is a need to standardize the format of prescriptions so that all essential information is included.

Published: January 2025

Background: District Health Information Software 2 (DHIS2) is an open source, web-based, health management information system (HMIS) recognized as world's largest HMIS platform, customized for health information system of Bangladesh for decentralized data entry since 2011. Health care managers and employees should be well informed about the health information system for accurate, appropriate, precise, timely, valid information and also interpretation of information which are the basis for policy planning and decision-making at various levels of the organization. The study aimed at exploring the limitations of DHIS2 in decision making process for health service management among the Upazila (Sub district) level health managers of Bangladesh. Methods: The cross sectional study was conducted among the Upazila Health and Family Planning Officers (UH&FPOs) of Bangladesh during the period of January to December 2018. All (482) UH&FPOs of Bangladesh posted as regular, current charge or in-charge were included for the study. Data were collected by a pre-tested semi-structured email-based questionnaire. Results: Response rate was 88.8% (428 out of 482). The mean age of the respondents was 47.08 (±6.33 SD). Mean duration of job experiences as UH&FPO was 1.9 years (±1.635 SD). Regarding limitation, the study revealed that 76.2% (of 424) UH&FPOs think that lack of rrealizing the Importance of DHIS2 by Doctors, Nurses and other Staffs is the most important “Facility Centered Barriers” for using DHIS2 as a decision support tool of Upazila health service management. Beside this 71.2% UH&FPOs think that lack of effective training of the staffs concerned with DHIS2 operation are the second most important barrier. The study also revealed that 59.7% (of 402) UH&FPOs think that absence of the option for automatically displaying the summary reports of various datasets in the respective Upazila dashboard is the most important “Software Centered Barriers” for using DHIS2 as a decision support tool of Upazila health service management beside this 58.5% UH&FPOs think difficulties in identifying the management related data elements from various data sets of DHIS2. Conclusion: So, this study recommends scaling up DHIS2 by redesigning training programs with more focus on the ways of its’ application in the decision making process, create awareness among all categories of health staffs, customization of its contents and more research on this ground. These initiatives will explore several innovative approaches to monitor health indicators by DHIS2, measure and plan health interventions to ensure quality health service and will lead towards achieving Sustainable Development Goal 3 (SDG-3).

Published: January 2025

У статті теоретично обґрунтовано та експериментально підтверджено методологію використання поляризаційної селекції навігаційних об'єктів, що перебувають на траєкторії руху судна в складних умовах атмосферного середовища судновим радіолокаційним поляризаційним комплексом. Показано, що використання дійсних енергетичних параметрів Стокса, дає змогу здійснити розпізнавання луна-сигналу навігаційного об'єкта на тлі луна-сигналів атмосферного утворення з використанням енергетичної матриці розсіювання та пристрою обробки луна-сигналу складного об'єкта (навігаційний об'єкт і атмосферне утворення) на виході приймача суднового радіолокаційного поляризаційного комплексу (СРПК). Теоретичною основою розпізнавання є радіофізична модель енергетичної матриці розсіювання з елементами, представленими параметрами Стокса та вимірюваними СРПК. Обрані опромінювані луна-сигнали навігаційного об'єкта й атмосферного утворення визначили вигляд енергетичної матриці розсіювання складного об'єкта та забезпечили функціонування СРПК в умовах складного атмосферного середовища під час розв'язування задачі поляризаційної селекції.Розроблено схеми обробки луна-сигналу складного об'єкта, що дали змогу виділити луна-сигнал навігаційного об'єкта з луна -сигналу складного об'єкта шляхом вимірювання елементів енергетичної матриці розсіювання. Обґрунтовано можливість використання енергетичної матриці частково поляризованої хвилі під час поляризаційної селекції навігаційних об'єктів, що перебувають у складних умовах атмосферного середовища. Енергетична матриця розсіювання дає змогу одержати в СРПК інформацію про поляризацію луна-сигналу частково поляризованої хвилі навігаційного об'єкта й атмосферного утворення шляхом вимірювання інтенсивностей їхніх луна-сигналів, які й розв'язують завдання поляризаційної селекції навігаційних об'єктів. Причому інтенсивність зливових випадних опадів вимірюється СРПК за першим параметром Стокса. Представлено результати експериментальної перевірки ефективності використання енергетичної матриці в поляризаційній селекції навігаційних об'єктів, які перебувають у зоні небезпечного для судноплавства атмосферного утворення.

Published: January 2025

Метою статті є розробка пропозицій щодо моделювання процесів подавання водно-паливних емульсій у суднових дизельних двигунах для підвищення ефективності їх функціонування. Поставлена мета досягається шляхом аналізу особливостей роботи дизеля на водно-паливних емульсіях, а також процесів сумішоутворення та паливоподачі при роботі на водно-паливних емульсіях. Встановлено, що на теперішній час впровадження водно-паливних емульсій в експлуатацію у суднових дизельних двигунах майже не реалізується. Доведено, що використання водно-паливних емульсій значно покращує експлуатаційні характеристики двигунів і є альтернативним паливом, оскільки вносить позитивні зміни у фізичний характер процесів подачі палива, сумішоутворення та згоряння, а також у механізм зносу і впливу навколишнього середовища на навколишнє середовище. Звичайно, використання водно-паливних емульсій водночас потребує певної зміни паливного обладнання і впровадження модуля підготовки транзиту водно-паливних емульсій, що може суттєво ускладнити установку двигуна. Досліджуючи рух водно-паливні емульсії в нагнітальному трубопроводі як двофазної рідини, визначені такі фізико-механічні властивості, як щільність, стисливість і швидкість поширення звуку. Найбільш суттєвим результатом є отримані залежності, що були наведені в статті в рамках моделювання процесів подавання водно-паливних емульсій у суднових дизельних двигунах. Під час математичного моделювання було отримано залежності, що описують зміну тиску та швидкості в процесі нагнітання палива на кількох ділянках суднових дизельних двигунів. Це дозволило виявити ряд локальних та інтегральних особливостей процесу, включаючи: обсяг палива, частку циклу подавання палива при посадці голки, кутове положення валу та максимальний тиск палива у порожнині насоса, на нагнітальному клапані та на інжекторі. Використання водно-паливних емульсій дозволяє знизити мінімальні стабільні швидкості на навантаженні та холостому ходу, а також відповідати вимогам ДСТУ, що значно підвищує ефективність функціонування суднового дизеля.
Ключові слова: судновий дизельний двигун, паливо, водно-паливні емульсії, математичне моделювання, викиди.

The characteristics of tourists play an important role in determining the tourist destinations they want to visit. The tourism potential offered on Pramuka Island is marine and coastal tourism. Snorkeling marine tourism has become one of the most popular diving attractions on Pramuka Island because it is quite safe and affordable. The high number of snorkeling tourism visits requires an analysis to enhance marketing planning that is more specific based on tourist characteristics, aiming to predict tourist needs, so that the interests and patterns of tourists who want to go snorkeling align with the target. The research method used is a quantitative descriptive method, with the sampling technique being accidental sampling. The research findings reveal that the characteristics of tourists in choosing snorkeling tourism destinations in Pramuka Island can be examined based on factors such as age, education, occupation, income, distance, origin, and frequency of visit

Optimizing the work accident and/or occupational disease prevention activity has as
its starting point the assessment of occupational injury and disease risks. The notion of risk is
defined in specialized literature by the probability with which an accident or an occupational
illness occurs in a work process with a certain frequency and severity of consequences. The
purpose of assessing the level of risk is to offer the possibility of knowing the real situation at
each workplace, from the point of view of work security, in order to take the most suitable
preventive measures for the given situation. The basis of the risk assessment principle consists
in taking into account two parameters: the frequency of accidents and the severity of the
maximum foreseeable consequence (principles also included in European standards)

Laser cutting is a computer numerically controlled process widely used in the
automotive industry for cutting metal materials needed to manufacture parts used in
automobile production. The production process represents all the conscious actions of a
company's employees carried out with the help of various machines, equipment, or
installations on raw materials, materials, or other components to transform them into
products or services with a certain market value. The Ishikawa diagram, also known as the
cause-and-effect diagram, is often used in industrial process analysis, defect prevention,
and product design processes. The paper presents the results of the research conducted on
the use of the Ishikawa diagram in analyzing the causes that lead to negative effects in the
laser cutting process of S235JRH structural steel pipes. After defining the problem, by
applying the "WHO, WHAT, WHERE, WHEN, HOW MUCH, HOW, WHY" method, all
possible causes were identified using the "5 Whys" method. The analysis identified 11
probable causes, and through further analysis, it was concluded that 3 of them were already
present in the process, influencing the laser cutting of the pipes and generating quality
problems. All the identified causes built the Ishikawa diagram consisting of 7Ms.

The need to reduce the mass of products manufactured by welding processes has led
to the replacement of the basic steel materials, such as construction steels, by steels with high
mechanical properties, such as hard and brittle steels. The increase of the mechanical properties
but also of the alloying degree has led to a decrease in the weldability of these materials. The
present paper presents the analysis of the welding possibilities with the gas metal arc welding
process of S890QL steel. The paper analyzes the hardness values obtained in the case of welding
technologies using two preheating temperature values (100 and 1500C) in the context of the
variation of the cooling time between 800 and 5000C. The values resulting from the hardness
measurements performed indicate that no significant changes in hardness occur in the
characteristic areas of the weld bead, the material not being subjected to additional hardening
processes. To analyze the weldability of the S890QL material, the results presented in the paper
must be correlated with the results of the mechanical tests performed on the welded joints.

Travelling is a fundamental activity for personal development, giving opportunities
for exploring, learning and enrich the cultural knowledge. Especially for young travellers, the
use of a backpack becomes a challenge due to its weight, limited space and the need of
transporting only the essentials. In the same time, the reduce mobility and the insufficient
comfort are elements that can cause the traveller experience. The project aims to reduce those
obstacles by developing an innovating product which combines two of the most chosen
electronics in travelling backpack: an iron and a hairdryer, integrating them into a compact, easy
to carry and light device. This product not only saves space but also meets the need for comfort
and convenience during travel. In technical terms, this project contributes to an ecological design
process by reducing the materials used in manufacturing and minimizing the resources required
for those products, individually. In a global context, where sustainability is crucial, the proposed
project considers not only the immediate needs of users but also the protection of the planet’s
resources for the future.

The paper presents a risk assessment and the action plan implemented for the welder
position using the INCDPM method. The method allows the prioritization of risks according to
their value and the efficient allocation of resources for labor protection. For the position analyzed
by the welder, 37 risk factors were identified. The overall risk level calculated for the analyzed
job is equal to 3.46, a value that places it in the category of jobs with an acceptable level of risk.
As regards the distribution of risk factors on generating sources, the situation is as follows:
37.84% of the contractor's own factors; 5.41% factors specific to the workload and 37.84%
factors specific to the means of production; 18.92% factors specific to the work environment.
The purpose of the risk level assessment is to provide the possibility of knowing the real situation
at each workplace, from the point of view of occupational safety, in order to take the most
appropriate preventive measures for the given situation. In order to avoid or reduce occupational
risks, occupational health and safety policies and procedures have been developed, in accordance
with the Romanian legislation in force in conjunction with the applicable legislation of the
European Union
What is it like to be a tetrachromat?
Authors: Newall Michael
Published: January 2025

Most people are trichromats, but some people have an extra kind of cone cell in their retinas: they are tetrachromats. Recent science shows that some tetrachromats make distinctions between reflectances that ordinary viewers are unable to detect. This paper asks what kind of colour experience these tetrachromats have. It rejects the claim that they simply see finer gradations of those colours familiar to trichromats. Instead, it draws on both scientific evidence and anecdotal data to argue that tetrachromats’ visual acuity is due to seeing novel colours: elementary colours that trichromat viewers are unable to see or imagine.
Campaign Spending Law & Politics for Constitutional Convention Referendums: A Case Study of Alaska
Authors: Snider J.H.
Published: January 2025

Fourteen U.S. state constitutions, including Alaska, require that at periodic intervals the people have the right to call a constitutional convention via a referendum. Alaska’s period is every ten years, and its last such referendum was in 2022. Its referendum illustrates certain latent tendencies of convention referendum law and politics, including severe collective action problems and corresponding campaign finance imbalances that campaign finance disclosure laws have not rectified. On a per capita basis, Alaska’s convention referendum had the fourth highest combined “yes” and “no” contributions and highest “no” and dark money contributions among the 140 U.S. state ballot measures across 38 U.S. states in 2022. High spending by the “no” campaign continued even after the “no” campaign knew it was essentially assured of victory. Such spending may be designed to deter future “yes” campaigns in Alaska and other states.
Political Science in Practice: Applied Research Projects as Career Preparation
Authors: Paci Simone
Published: January 2025

Curricular activities can bridge the gap between political science education and its application across professional fields. This study introduces a seminar final project format that modifies the traditional academic paper with diverse, real-world outputs, such as public policy white papers, lobbying memos, or long-form journalism. This innovative approach achieves three goals: fostering active learning, sharpening research skills, and providing professional preparation by simulating practical uses of political science. To ensure rigor and equity across formats, the project follows a milestone-based structure, guiding students through iterative submissions, including a research question, argument, and data plan. Drawing on evidence from two quarter-long Stanford University seminars, I assess the strategy’s impact using student surveys, interviews, and classroom observations. The findings indicate that this assessment format offers a valuable professionalizing experience, equipping students with the tools to apply political science insights effectively in varied career paths.
No-Go Theorem Requires Modification: An Additional Constant Term $C$ and Its Laurent Series Structure in f(R) gravity
Authors: CHEN WEN-XIANG
Published: January 2025

No-go theorems often assert that certain solutions or configurations in gravitational and field-theoretic models cannot exist under a prescribed set of assumptions~\cite{NoGoClassic}. However, recent analyses using a \emph{modified} Robson-Villari-Biancalana (RVB) approach~\cite{RobWilcz1,BanKul1,BanKul2} indicate the presence of an additional integration constant, $C$, that may appear in topological or horizon-based integrals (notably through expansions in Laurent series). This subtle term invalidates the usual dismissal of boundary or horizon contributions and demands a revised understanding of no-go arguments. In this work, we demonstrate how $C$ can be revealed through careful Laurent expansions about the horizon and discuss why ignoring this term undermines the classical no-go statement. We illustrate these ideas with examples in $f(R)$ gravity~\cite{fR-Review1,fR-Review2,fR-Review3}, emphasizing how familiar no-go theorems must be updated to accommodate the extra freedom that $C$ provides.

It is widely acknowledged that the world is currently experiencing an unprecedented water shortage, with agriculture being a crucial contributor. This paper presents a synthesis of available evidence, identify knowledge gaps, and make a state-of-the-art synthesis on green water management in Ethiopia. A systematic review methodology was implemented, encompassing the compilation and analysis of peer-reviewed and gray literature. The paper demonstrates that rainfed agriculture, which relies on “green water” (soil moisture from rainfall), accounts for 80% of cultivated land and 60-70% of global crop production. However, green water management has not received adequate attention in water policy and land rehabilitation programs in Ethiopia, where irrigation is limited. The analysis reveals a large yield gap and water productivity gap for major crops like maize, sorghum, and wheat in Ethiopia’s rainfed agriculture. Increasing crop yields through better soil, water, and crop management practices can significantly improve water productivity, offering “windows of opportunity” to enhance food and water security. Thus, a paradigm shift from the traditional narrow focus on soil erosion control towards an integrated green-blue water management approach in water and agricultural policies and programs is urgently required. Increased investments and expertise in green water management at the government level are crucial. Optimizing the use of green water resources in rainfed farming can also unlock Ethiopia’s export potential while improving domestic water and food security through strategic virtual water trade. In conclusion, the review highlights unlocking the potential of green water resources through targeted investments and policy support for rainfed agriculture can significantly contribute to Ethiopia’s water and food security objectives in a cost-effective and environmentally sustainable manner.
Ditch management using low-grade weirs: an opportunity for mitigating water quality and quantity impacts
Authors: Strock J. S. , Ranaivoson A. Z.
Published: January 2025

To improve productivity, extensive agricultural areas in the Midwest United States require drainage systems consisting of subsurface drainage (tile) and open ditches. Transport of sediment, pathogens, pesticides, and nutrients from runoff and drainage from crop fields contributes to eutrophication and degradation of surface waters. Solutions are needed to improve environmental quality and reduce the negative impacts from runoff and agricultural drainage systems. This study assessed the effect of low-grade weirs on discharge and nitrate-nitrogen concentration and loss from a pair of experimental drainage ditches. One control (without weirs) and one treatment (with weirs) ditch were studied from 2017 through 2023 at the University of Minnesota, Southwest Research and Outreach Center near Lamberton, MN, United States. This study was the first evaluation of agricultural ditches, with and without low-grade weirs, and their potential to mitigate discharge and nitrogen loss in a cold climate. Stage-discharge data were collected using a data logger and bubble level sensor. Water samples were collected for water quality analysis daily using automated samplers. Analysis of the data was conducted using paired t-tests and a paired analysis approach. Analysis of covariance and linear regression of the treatment ditch against the control ditch were highly significant for nitrate-nitrogen concentration and load. The ditch with the low-grade weir was found to significantly decrease nitrate-nitrogen concentration and load. More specifically, the treatment ditch reduced discharge, nitrate-nitrogen concentration and load by 51%, 22% and 58%, respectively. The greatest discharge from the ditches occurred in March while most nitrogen losses occurred between May and June. This study provides evidence and highlights the potential of ditches equipped with low-grade weirs to reduce nitrate-nitrogen losses when compared to ditches without low-grade weirs in a cold climate. In addition, the study also emphasizes the importance of climate as a driver of nitrate-nitrogen loss from crop lands and ditches which is amplified by monthly precipitation variability.
Characterization of novel human endogenous retrovirus structures on chromosomes 6 and 7
Authors: Pasternack Nicholas , Paulsen Ole , Nath Avindra
Published: January 2025

Human endogenous retroviruses (HERV) represent nearly 8% of the human genome. Of these, HERV-K subtype HML-2 is a transposable element that plays a critical role in embryonic development and in the pathogenesis of several diseases. Quantification and characterization of these multiple HML-2 insertions in the human chromosome has been challenging due to their size, sequence homology with each other, and their repetitive nature. We examined a cohort of 222 individuals for HML-2 proviruses 6q14.1 and 7p22.1a, two loci that are capable of producing full-length viral proteins and have been previously implicated in several cancers, autoimmune disorders and neurodegenerative diseases, using long-read DNA sequencing. While the reference genome for both regions suggests these two loci are structurally dissimilar, we found that for both loci about 5% of individuals have a unique tandem repeat-like sequence (three long terminal repeat sequences sandwiching two internal, potentially protein coding sequences), while most individuals have a standard proviral structure (one internal region sandwiched by two long terminal repeats). Moreover, both proviruses can make full-length, or nearly full-length, HERV-K proteins in multiple transcription orientations. The amino acid sequences from different loci in the same transcriptional orientation share sequence homology with each other. These results demonstrate a clear, previously unreported, relationship between HML-2 loci 6q14.1 and 7p22.1a and highlight the utility of long-read sequencing to study repetitive elements. Future studies need to determine if these polymorphisms determine genetic susceptibility to diseases that are associated with them.
