Authors: Yarangga Christine M W , Purcahyono Joko , Sitorus Yannice L  M
Published: October 2024

Kawasan permukiman di Kelurahan Yabansai mengalami banjir saat terjadi hujan deras di Kota Jayapura pada awal tahun 2022. Bencana banjir dan diikuti longsor ini menyebabkan korban jiwa di Kota Jayapura, tetapi di Kelurahan Yabansai, hanya menimbulkan kerugian material bagi warga setempat. Kelurahan Yabansai terletak di kawasan berbukit hingga landai dengan permukiman yang relatif padat penduduknya. Tujuan penelitian ini untuk mengetahui kesiapsiagaan masyarakat dan menyusun strategi penanganan banjir berbasis pemberdayaan masyarakat di Kelurahan Yabansai, Distrik Heram, Kota Jayapura. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif dan kualitatif serta menggunakan metode analisis deskriptif. Identifikasi kapasitas warga Kelurahan Yabansai dalam menangani banjir dilakukan lewat penyebaran kuesioner, dan informasi lainnya diperoleh lewat observasi dan wawancara dengan tokoh masyarakat setempat. Hasil penelitian menunjukan bahwa ada lima titik lokasi potensial banjir di kawasan permukiman Kelurahan Yabansai dan sebagian besar masyarakat belum siap siaga dalam menghadapi bencana banjir. Penyebab banjir antara lain: drainase belum berfungsi dengan baik akibat sedimentasi, adanya sampah serta ditumbuhi oleh rerumputan, dan ada beberapa tempat belum memiliki saluran drainase. Strategi penanganan banjir berbasis pemberdayaan masyarakat lebih ditekankan pada upaya mitigasi nonstruktural, yaitu: sosialisasi atau penyuluhan kepada masyarakat tentang penanganan bencana banjir.
Pollen Cross-Reactivity: A Primer for Allergy Specialists
Authors: Sowers Tricia
Published: October 2024

There are over 400,000 land-based plant species that comprise our biodiverse habitat. Only a small subset of those plant species satisfies Thommen’s postulates, classifying them as allergens. The number of allergenic species, however, remains so vast that it is prohibitive to both test and treat for all relevant species within a geographical region. Allergy specialists have a valuable tool that can be used to help simplify the management of allergic patients: cross-reactivity. 
Cross-reactivity is the ability for an allergen to induce an IgE-mediated response, regardless of previous exposure. Allergens are a complex milieu of proteins, some of which have allergic potential while others do not. A number of proteins are conserved across allergen species. When exposure to these conserved proteins occurs, the immune system recognizes them in a similar manner. For homologous or cross-reactive allergenic proteins, this conserved molecular recognition initiates the allergic cascade. Allergen characterization is critical to the understanding of cross-reactivity. Characterization, in this context, refers to the protein make-up of a particular allergen. The process of allergen characterization began in 1962 with the discovery of antigen E, the first identified allergenic protein. Antigen E, commonly known as Amb a 1, is an allergenic protein in ragweed, and is the primary sensitizing protein for ragweed allergy sufferers. These primary sensitizers are referred to as major allergens and can be defined as such when >50% of the allergic patient population is sensitized to them. An entire branch of research arose from this discovery, which has allowed for major advances to be made in the understanding of cross‑reactive relationships among allergen species. Cross‑reactivity is not limited to homologous major allergen expression. Rather, minor allergens and panallergens, though less clinically relevant, play a similar role in cross‑reactive relationships. This primer will explore the science behind cross‑reactivity, as well as provide a general overview of the cross‑reactive relationships that have been defined for plant allergens found across North America.
Low-tech Treatments for Acne Scarring: CROSS, Subcision, and Injectables
Authors: Richer Vincent
Published: October 2024

Dermatologists routinely treat acne with the objective of preventing acne scarring. Once control of acne has been achieved, our patients are often keen to improve textural skin changes such as atrophic acne scars. We often equate the management of atrophic acne scars with the need to reach for high-tech devices such as resurfacing lasers or radiofrequency-microneedling. While these modalities can play a pivotal role in resurfacing the skin, low-tech treatments can also be used in monotherapy or combination treatment to improve specific types of acne scars. In this article, we discuss the CROSS technique, subcision, and the use of injectables for acne scars.
Sjogren’s Syndrome: Strategies for Treatment
Authors: Bookman Arthur A.M.
Published: October 2024

Sjogren’s syndrome, characterized by dry eyes, dry mouth, and immunological hyperactivity, has been one of the most difficult rheumatic diseases to differentiate and define. After many hours of consensus group development, studies on large cohorts/registries of over 1500 patients in totality and following national, European, American, and finally consensus iterations, criteria have been agreed upon for the classification of this disease. In the final analysis, these criteria are objective and accessible for measurement, and a number of them can be documented in clinical practice. To treat Sjogren’s syndrome effectively, it is important to rely upon objective evidence with respect to the diagnosis of this disease, as well as the specific component of the condition that one is attempting to manage.
Um balanço da "questão" das drogas no início do terceiro governo Lula
Authors: Pedro Henrique Antunes da Costa
Published: October 2024

Analisamos o início do terceiro governo Lula quanto à “questão” das drogas. Recorremos a fontes e dados estatais e de importantes atores, movimentos e à literatura acadêmica. Há muitas contradições atentando contra a Reforma Psiquiátrica e o Sistema Único de Saúde. Há um avanço privatista, manicomial e conservador, tendo as Comunidades Terapêuticas (CTs) como carro-chefe, não só expressando a conjuntura e a correlação de forças, mas as reforçando. Em nome da conciliação (do que não é conciliável), chancela-se a hegemonia manicomial, repressiva e criminalizadora das políticas sobre drogas, só que em volume, velocidade e intensidade únicos. Sinalizamos os principais retrocessos implementados, os quais devem ser revogados para políticas mais humanizadas, assegurando e fortalecendo direitos, a partir da Reforma Psiquiátrica e da Redução de Danos. Nisso, é mister o fim do financiamento público das CTs e o fim delas e de outros manicômios.
Redes vivas de saúde frente às maternidades sequestradas
Authors: Simões de Souza Isadora , Gonçalves Vicentin Maria Cristina
Published: October 2024

Neste texto discutimos a produção de redes de saúde como estratégia de enfrentamento ao   intolerável da retirada de bebês, mais especificamente daquelas mulheres em situação de rua e/ou usuárias de drogas, que passam a ter seus direitos cerceados, como o de ver ou serem informadas do paradeiro institucional de seus filhos. Visando compreender tal operação, que chamamos de sequestro, traçamos, por meio de entrevistas, os itinerários de mulheres usuárias de drogas que lutam para reaver ou reconstruir a história de seus filhos, bem como as ações de profissionais que construíram estratégias de enfrentamento destas violações. Tomando como fio condutor duas histórias que se entrecruzam, na cidade de Belo Horizonte, a de uma mãe e a de uma médica pediatra, evidenciamos: o desmentido como modo de operar o sequestro e a configuração de “redes vivas” como caminho do cuidado em resposta à “rede fria” da violência de estado.

ОСОБЕННОСТИ ЗАИМСТВОВАННЫХ СЛОВ В РУССКОМ ЯЗЫКЕ В СОВРЕМЕННОЙ ТЕРМИНОЛОГИИ МЕЖДУНАРОДНОГО ТУРИЗМА
Authors: Умирзакова З.А. , Кадырова Г.Р.
Published: October 2024

В данной статье нами проведён анализ материалов, раскрывающий типологические особенности терминов международного туризма в русском языке.
Методами исследования стали анализ литературного материала (специальной лингвистической и педагогической литературы), сравнительный и сопоставительный анализ о заимствованной лексике в предметной терминологии и контекстный анализ материала.
Установлено, что особенностями современного заимствования русского языка в области международного туризма является преимущественное использование американизмов, так как английский язык является международным, на его основе создаются международные термины. Активность процессов заимствования терминов международного туризма в современный период определена потребностями русского языка по исследованию иноязычных аббревиатур и стремлению к универсализации, языковой экономии и туристическими интересами гражданского общества.
В системе русского языка новые заимствованные слова образованы в основном прямыми заимствованиями (транскрипция, транслитерация, вкрапления), кальками или непрямыми заимствованиями (синтаксические, семантические, переносный смысл). Применяются довольно активно полукальки или гибридные образования. Терминологический состав международного туризма новейшего периода в русском языке образуется заимствованными словами особой категории (термины и аббревиатуры). За счёт неологизмов значительно расширена в русском языке терминологическая языковая система международного туризма.
Научная значимость характеризуется тем, что в исследовании представлены состав, содержание, раскрыты аналитические характеристики создания современной терминологии международного туризма в русском языке, образованных на основе новых заимствованных слов, внутреннего отраслевого характера и терминов, не связанных с международным туризмом.
Практическая значимость исследования заключается в том, что его результаты будут включены в учебное пособие по русскому языку для всех специальностей групп образовательных программ «В 091 -Туризм», «В093 – Ресторанное дело и гостиничный бизнес», что позволит использовать их при преподавании русского языка, в профессиональном туризме и населением в процессе общения.

Published: October 2024

Acne vulgaris adalah penyakit peradangan kulit yang meskipun tidak membahayakan jiwa, dapat memengaruhi estetika dan rasa percaya diri, bahkan menyebabkan kecemasan dan depresi, terutama pada remaja. Prevalensi tertinggi acne vulgaris terjadi pada usia 16 hingga 18 tahun, baik pada remaja laki-laki maupun perempuan. Salah satu faktor yang memengaruhi acne vulgaris adalah kebersihan wajah atau Personal Hygiene. Kebersihan wajah yang buruk menyebabkan kulit kotor dan berminyak, sehingga bakteri Propionibacterium acnes mudah berkembang biak dan menyebabkan acne vulgaris. Penelitian ini bertujuan untuk mengetahui hubungan antara personal hygiene wajah dan keparahan acne vulgaris pada remaja SMA Negeri 3 Jakarta. Penelitian ini menggunakan metode survei analitik dengan rancangan potong lintang pada 91 siswa yang dipilih secara consecutive sampling. Data personal hygiene dikumpulkan melalui kuesioner, sedangkan keparahan acne vulgaris diukur menggunakan Global Acne Grading System (GAGS). Hasil penelitian menunjukkan hubungan bermakna antara personal hygiene wajah dan keparahan acne vulgaris, dengan p-value 0,000 dan korelasi negatif tinggi (r = -0,610). Sebum berlebih yang bercampur dengan kotoran dapat menutup pori-pori, menyebabkan inflamasi dan acne vulgaris. Remaja laki-laki cenderung memiliki keparahan acne vulgaris lebih tinggi dibandingkan perempuan, karena perempuan lebih menjaga kebersihan wajahnya.

Published: October 2024

Engineering works greatly influence the lateral channel migration (LCM) of meandering rivers. We aimed to characterise the spatiotemporal characteristics of LCM during the last 174 years of the almost freely meandering Upper Rába (Hungary) and to identify units with distinctive LCM histories. The studied Rába's reach has been regulated just at some points. Due to the free meandering, its length varied between 119 and 133 km. The most intensive length increase (+291 m/y) took place between 2005 and 2008, and by the end of the process , the sinuosity had reached its historical maximum (SI 2018 = 1.93). The mean LCM was 3.3 m/y (1844-2018). The periods with intensive channel migration (max: 24-27 m/y) were followed by periods with low migration rates. Based on local channel morphology and LCM rates, 14 units were identified. The highest LCM rate was measured in the freely migrating units (R5: 5.8 m/y; R3: 4.4 m/y and R6 4.0 m/y).

Published: October 2024

Small trade formats, like traditional trade formats, play a significant role in the trade sector and on the consumer goods retail market in the Republic of Serbia with a network of around 12.000 retail stores. On the other hand, the issue of productivity in trade in the conditions of labor deficit in this sector is increasingly important. The paper deals with the research of the productivity of retail stores with an emphasis on smaller trade formats such as independent trade shops. An analysis of the productivity and differences in the productivity of these trade formats was carried out in relation to the size of these stores and the degree of urbanity of the locations where they are located, using the example of consumer goods retail stores of a trade chain in one of the largest cities of the Republic of Serbia. The research analyzed more than 4000 data on sales of these stores in 2022, which were put in relation to the number of employees of individual retail stores. The results of the analysis are given by month as well as by quarter for the entire 2022. The analysis was carried out using parametric statistical tests. Precisely, the t test was used to determine differences in productivity based on the urbanity of the location of the retail store and ANOVA was used to determine differences in productivity based on the size of the retail store. The work aims to determine the existence of differences in the productivity of retail stores of fast-moving consumer goods in relation to their individual size and the degree of urbanity of the location where these stores are located.

Authors: Benahmed Abdelkrim , Bouguenina Otbi , Meksi Ali , Benmahdi Khaled , Bendahane Khaled , Sadoun Mohamed
Published: October 2024

Introduction/purpose: The dynamic analysis of a seismic response of a concrete vault dam is a complex problem in which the representation of the behavior of the material requires some form of a nonlinear model, especially if the concrete is subjected to a significant stress load of the ground. In the case of large movements of the latter, large cracks may form in some areas of the dam, especially at the base of the dam and near sudden changes in geometry. Methods: This analysis was based on a numerical simulation of the dynamic effect. This work was carried out using the finite element method with the ANSYS 12.1 program. The dam was modelled in two dimensions. Four types of analysis were performed: static analysis, modal analysis, seismic analysis under excitation of two accelerograms (Asnam 1980 and Boumerdes 2003), and spectral analysis. Results: This analysis showed the vulnerability of the Brezina dam to the Boumerdes earthquake with high stresses at the base of the structure. Conclusions: Based on this study, it was concluded that if the Brezina dam suffers an earthquake of a greater intensity than that of Boumerdes, this will cause structural damage and cracks that will compromise the dam's watertightness as well as its durability.
Some considerations on the total stopping time for the Collatz problem
Authors: Fabiano Nicola , Mirkov Nikola , Radenović Stojan
Published: October 2024

Introduction/purpose: The Collatz conjecture has been considered and the stopping time needed for the recursive transformation to end has been investigated. Methods: A statistical analysis on the stopping time has been used. Results: The statistical approach shows that the probability of finding an infinite stopping time, that is a violation of the Collatz conjecture, is extremely low. Conclusion: Picking precisely one particular atom in the Universe is still more favorable, by more than 61 orders of magnitude, than encountering an infinite total stopping time.
Analytical investigation on the buckling and free vibration of porous laminated FG-CNTRC plates
Authors: Ghazoul Tahir , Benatta Mohamed , Khatir Abdelwahhab , Beldjelili Youcef , Krour Baghdad , Bachir Bouiadjra
Published: October 2024

Introduction/purpose: The aim of this study is to examine the buckling and free vibration behavior of laminated composite plates reinforced with carbon nanotubes when various sources of uncertainty are taken into account with 1 the main focus being the existence of porosity. Methods: A porous laminated plate model is developed using a high order shear deformation theory. Different configurations of functionally graded aligned single-walled carbon nanotubes throughout the thickness of each layer are being investigated. The effective properties of materials are evaluated through the extended rule of mixture while considering an upper bound for the effect of porosity. The governing equations are derived and solved using the virtual work principle and Navier's approach. The validity of the current formulation is confirmed by comparing the results with the existing data from literature sources. The impact of numerous parameters such as porosity, carbon nanotube volume fraction, reinforcement distribution types, lamination scheme, and the number of layers on the buckling and free vibration responses is investigated in detail. Results: A key finding of this study is the significant reduction in buckling resistance of laminated FG-CNTRC plates due to porosity, contrasting with the minor impact on the free vibration response. Conclusion: The results of this paper emphasize the critical role of porosity in structural integrity and provide novel insights into the behaviour of advanced composite materials.

Airline Price prediction using ExtraTrees Regressor
Authors: Mahesh Sharma Rupam Kumari , Sarwath Unnisa
Published: October 2024

Airlines employ dynamic pricing strategies, which are based on demand estimation models, to set ticket prices. Airlines often set the price of their seats based on the necessary demand because they can only sell a certain number of seats on each journey. Airlines typically raise travel costs during times of strong demand, which slows down the rate at which seats are filled. When demand declines and seats become unsold, airlines typically lower their ticket prices to draw in new passengers. It will be more beneficial to sell those seats for more than the cost of service per passenger because unsold seats result in a loss of revenue. In order to forecast airline ticket prices, the primary objective of this study was to determine the factors influencing airline ticket costs and look into the relationships between them. Consequently, a model is created to predict the cost of plane tickets, allowing consumers to make better-informed decisions regarding their purchases. The cost of airline tickets in India is then predicted by this study using Four different machine learning algorithms: Extra Trees Regressor, XG Boost Regressor, Random Forest, and Decision Tree. Furthermore, hyperparameter optimization is done to obtain the most accurate and ideal prediction results. The Extrat Trees regressor yielded the greatest results, with the lowest RMSE of about 1807.59 and the highest accuracy of nearly 88%.

Published: October 2024

Objective: Identify the best method for treating overweight/obesity in adults by analyzing their characteristics, benefits, and side effects. Methods: This is an integrative review composed of the following stages: 1. formulation of the guiding question; 2. literature search; 3. data collection; 4. critical analysis of the articles; 5. discussion of the results; 6. presentation of the integrative review. The databases Pubmed, BIREME, and SCIELO were consulted. Inclusion criteria were articles available in full, published in the last 5 years (2020 - 2024 ), in English or Portuguese. Articles were transferred to Rayyan software, where duplicates and those not meeting the inclusion criteria, such as studies on children and review articles, were excluded. Results: The results showed that Tirzepatide, compared to Semaglutide, was superior in reducing BMI, abdominal circumference, and weight percentage. Adverse effects occurred in both studies, mainly gastrointestinal, with no preference for either drug to reduce these effects. Comparison between Semaglutide or Tirzepatide versus Bariatric Surgery was not possible, as no studies addressing this comparison were found. Conclusions: Future research comparing medicinal and surgical approaches for weight reduction in obese patients is necessary to determine the best treatment, considering both weight reduction and undesirable post-treatment effects. More research on weight regain after study completion is also needed

To investigate the effects of intercropping of maize with sugarcane on cane development, outturn, and overall economic return, field experiments were carried out during the cropping year 2021–22 in two different locations: Bangladesh Sugarcrop Research Institute (BSRI), Ishwardi, Pabna and the Regional Sugarcrop Research Station (RSRS), Thakurgaon, Bangladesh. There were nine treatments namely T1 : Single row sugarcane only (SS), T2 : SS+ Maize (During sett placement), T3 : SS+ Maize (7 days after sett placement), T4 : SS+ Maize (14 days after sett placement), T5 : SS+ Maize (21 days after sett placement), T6 : SS+ Maize (28 days after sett placement), T7 : SS+ Maize (35 days after sett placement), T8 : SS+ Maize (42 days after sett placement), T9 : Maize (M) only. Sugarcane variety “Isd 39” and maize variety “Super 92” were used in this experiment as experimental materials. Results indicated that T7 treatment was superior in terms of germination (56.56% at BSRI and 57.33% at Thakurgaon). The treatments T1 (174.33×103 ha-1 and 184.00×103 ha-1) and T7 (162.67×103 ha-1 and 168.00×103 ha-1) consistently exhibited superior tiller production and millable cane yield at both the locations. However, T1 generally resulted in higher cane yield, while T7 demonstrated higher SEY (108.25 t ha-1 at BSRI and 114.79 t ha-1 at Thakurgaon), LER (1.56 at BSRI and 1.52 at Thakurgaon), ATER (1.20 at BSRI and 1.16 at Thakurgaon), gross monetary value (487133 BDT ha-1 at BSRI and 516533 BDTha-1at Thakurgaon), and monetary advantage index (175178 at BSRI and 177542 at Thakurgaon) compared to other treatments. Treatment T2 also showed competitive SEY (105.52 t ha-1 at BSRI and 108.69 t ha-1 at Thakurgaon), LER (1.64 at BSRI and 1.54 at Thakurgaon), ATER (1.13 at BSRI and 1.07 at Thakurgaon), gross monetary value (474867 BDT ha-1at BSRI and 489100 BDT ha-1at Thakurgaon), and monetary advantage index (184942 at BSRI and 173134 at Thakurgaon), indicating its effectiveness in enhancing sugarcane production. Therefore, it maize planted 35 days after sugarcane sett placement (T7 ) or during sugarcane sett placement (T2 ), profitable intercropping system.

An experiment was conducted at the ICAR-Indian Agricultural Research Institute in New Delhi during the rainy (Kharif) seasons of 2021–22 and 2022–23. The study aimed to evaluate the weed control efficiency of low dose new generation herbicide: tembotrione (34.4% SC) as a component of integrated weed management (IWM), on zero-till (ZT) and conventional till (CT) maize (Zea mays L.). The treatments were comprised of conventional tillage maize (M1: CT-M), conventional tillage maize with green manure from preceding green gram (M2: CT-M+GM), zero tillage maize with residue retention at 3 t/ha (M3: ZT-M+R), zero tillage maize with Sesbania co-culture as brown manuring (cover crop) (M4: ZT-M+BM) in the main plot and five weed control treatments, viz S1: Un- weeded check, S2: Pre +1 HW, S3: Pre + Post (tembotrione) @120g/ha, S4: Pre+ Post (Premix of Mesotrione+ Atrazine) @120 g/ha, S5: Weed free check (WFC) in the sub-plots were evaluated in split-plot design. It was ob- served that ZT-M+BM caused a considerable reduction in the population of broad-leaf weed, narrow leaf weed with sedges and total weeds (28.4% reduction at 60 days after sowing) compared to M1. The results also revealed that the sequential application of atrazine @750g/ha+pendimethalin @750g/ha(pre) followed by (fb.) tembotrione (34.4% SC) @120 g/ha (post) among the herbicide options reduced the weeds population (78.5%) and dry weight (81.3%) significantly than the un-weeded control (UWC). Maize yield attributes were higher in ZT with Sesbania co-culture (ZT-M+BM) than conventional-tilled treatments (CT-M). The application of atrazine @750g/ ha+pendimethalin @750g/ha (pre) fb. tembotrione @120 g/ha (post) combined with ZT-M+BM resulting in higher maize yield (6.88 t/ha) which was comparable with that in weed-free check (WFC). The post emergence (PoE) ap- plication of tembotrione (34.4% SC) @120 g/ha recorded highest weed control efficiency (86.2%), weed control in- dex (88.1%) and lowest value of weed index (7.04) when applied in the ZT-maize with sesbania as a cover crop. Therefore, combining zero tillage (ZT) with brown manure (Sesbania), along with atrazine and pendimethalin (@750g/ha each) as pre-emergence herbicides, and tembotrione (@120g/ha) as a post-emergence herbicide is recommended for effective weed control and high maize productivity in the North-Western Indo-Gangetic plains (IGP).

A ground-breaking and enduring way to significantly reduce the use of conventional nitrogen fertilizer is to use nano-urea as a nitrogen supplement. The combination of nano and prilled urea was investigated in this study to address this issue and allowing for a 25% reduction in the recommended urea dosage. Research on rainfed maize during kharif season was conducted at ICAR-IARI Jharkhand. Twelve different combinations of conventional prilled urea, nano and prilled urea spray were investigated in the study. In the fields, the experiment used a randomized block design. Different treatments included applying prilled urea as a 2% solution in 150 liters of water per hectare and nano-urea at a rate of 1250 ml/acre applied twice through foliar application. Results showed that applying two additional applications of nano-urea along with 75% of the recommended dose of prilled-urea was the most successful fertilization strategy. This performed statistically equal with both the 100% recommended dose and the 100% recommended dose with two prilled urea spray applications in terms of yield, and cost-to-benefit ratio. The study's findings show that nano-urea can safely replace at least 25% of the dosage of prilled urea i.e. recommended, providing a more profitable and environmentally friendly method of cultivation.

A field experiment was laid out during 2023-24 at ICAR- Indian Agricultural Research Institute, New Delhi to study the effect of various nutrient management options on growth performance, yield and quality of sugarcane. Optimized integration of organic sources were evaluated with inorganic nutrient sources in randomized block design with three replications. The result revealed that a significantly higher plant height (407.8 cm), number of tillers (191 × 103/ha), leaf area (511.7 dm2), leaf area index (6.81) and cane yield (91.2 t/ha) of sugarcane were obtained with the integration of 100% synthetic along with 4 t/ha solid digest, which was at par to 100% NP + K through liquid digest, 100% synthetic + 6 t/ha biochar and 100% NP + K through Ash, while the lowest were observed under treatment receiving organic manure alone i.e. 100% N through solid digestate, might be owing to very slow mineralization process of nutrients. These treatments also resulted in an effective combination of organic and inorganic nutrient sources with regard to increased 0brix reading.
