Published: September 2024

Microclimate differences in water availability can diversify seasonal
water use and photosynthetic strategies among co-occurring tropical tree
species, especially in forests with strongly seasonal climates. We
studied a tropical forest site in the Western Ghats, India, and
characterised seasonal differences in photosynthetic CO
2 assimilation rates ( A net)
among three tree species groups spanning leaf habit and topographic
affinity: deciduous species in dry hilltops, dry-affinity evergreens on
slopes, and wet-affinity evergreens in valleys. As expected, deciduous
species on dry hilltops showed higher P opt (
A net at optimal temperature, T
opt) during the wet period, while evergreen species
showed no overall seasonal differences. Interestingly, dry-affinity
slope evergreens showed higher P opt during the
dry period compared to the wet period despite lower soil moisture,
suggesting sufficient water availability and warmer thermal niche
preference. Across species, stomatal conductance ( g
s) at T opt was generally higher
during the wet period, except for one evergreen species. Surface soil
moisture was lowest in hilltops, intermediate on slopes, and highest in
valleys, with higher levels during the wet period compared to the dry
period. Our findings highlight the diverse seasonal photosynthetic
strategies among tropical tree species with different leaf habits and
water affinities.
The effects of the volatilities in global determinants on the Istanbul stock exchange
Authors: Köse Nezir , Ünal Emre
Published: September 2024

This study investigates the impact of the VIX, volatility in the oil price,
gold price, exchange rate, interest rate, and traded value on volatility in
the Istanbul stock exchange. The structural vector autoregression (SVAR)
model and pairwise and multivariate Granger causality tests were utilized
for weekly data ranging from January 2002 to November 2020. According to
causality tests, the volatility in global determinants were the primary
factors that determined the volatility in the stock exchange. The variance
decomposition analysis indicated that the VIX was the main contributor to
stock exchange volatility, and its influence increased in successive time
periods. The impact of the volatility in the gold price had the second
highest influence, while the influence of the oil price remained more
limited. The volatility in the stock exchange was significantly affected by
volatility in the exchange rate, but the significance of its movements
decreased over time. In the early stages, the gold price had no effect, but
then it started to have a significant and continuous positive impact. The
volatility in the oil price was initially positive and significant, but
after a few weeks, its influence became insignificant. Interest rate
volatility was insignificant, but exchange rate volatility remained positive
and significant for a few of weeks. The volatility in traded value initially
appeared insignificant, but it eventually became significant, had a positive
influence, and had a long-lasting effect on stock exchange volatility.
Hence, the VIX is the most important global driver of stock exchange
volatility in both long and short terms.

Published: September 2024

Population-based epidemiological studies on disease burden and risk factors for psoriatic arthritis (PsA) in patients with psoriasis (PsO) are limited, especially in Asian populations. Therefore, the aim was to determine the prevalence and incidence of PsA among PsO patients in Korea, and examine associated clinical factors. A cohort study was performed to determine the annual prevalence and incidence of PsA among PsO patients between 2008 and 2020 using nationwide claims data in Korea. Risk factors for PsA development were also examined using logistic regression among matched PsA cases and controls. An increasing trend in PsA prevalence per 1,000 patients was observed; prevalence was 6.17 (95% confidence interval [CI] 5.73–6.65) in 2008 and 19.03 (95% CI 18.39–19.70) in 2020. Similarly, the PsA incidence rate per 1,000 patient-years increased from 3.35 (95% CI 3.01–3.72) in 2008 to 5.01 (95% CI 4.68–5.36) in 2020. Patients with plaque PsO, moderate-to severe PsO, receiving oral systemic therapy or phototherapy, with a higher burden of comorbidities, and concomitant autoimmune diseases had a higher risk of PsA. The results provide insight into the burden of PsA among PsO patients in Korea and risk factors associated with developing PsA.

Published: September 2024

Investing involves putting money into a variety of asset classes for a predetermined amount of time in the hopes of increasing total value and producing more income. The goals of investments and economics, such as value creation, profit generation, and other related goals, are strongly correlated. It is critical to recognize that investments may include additional financial, social, and spiritual goals. This research aims to assess investor behavior from internal and external perspectives concerning investing decisions. This study employs the Structural Equation Model (SEM) methodology utilizing the Smart-PLS software. This study's findings demonstrate that qualities including anger, anxiety, overconfidence, and self-monitoring positively influence investment decisions. Herding mitigates the adverse impacts of anger, anxiety, overconfidence, and self-monitoring on investment decisions. This research's consequences can assist investors in circumventing irrational risks and yield more objective findings grounded in thorough study. This tendency can result in inefficient market transactions, asset bubbles, and significant volatility. This study arose as a counter to the conventional understanding of exchange markets predicated on the premise of trader rationality. This research identifies that emotional emotions, risk perception, and cognitive biases frequently affect investment decisions by comprehending human nature.

Authors: PUTRA ORLANDA MAHARI , Hadiana Muhammad Hasan , Hidayati Yuli Astuti
Published: September 2024

A study on livestock waste treatment at farm level has been carried out on members of a dairy farmer group in Lembang District, West Java Province, aiming to examine the potency of income incentive for farmer, as well as whether there is a relationship between farm-output and cattle size with farmers' decisions to improve the waste treatment commercially. The study is a case in a farmer group with 30 members of farmer. The data were analyzed descriptively. Non-parametric analysis are used to examinne how farmers' attitude resistance against the improvement in waste treatment. The results shows that the  livestock waste treatment provides additional benefits. With having an average cattle-size of 4.6 LSU, the farmers obtain benefit equal to an income  increase of IDR 4.26 million/year.  Improvement waste treatment leads to the economic productivity of each LSU increased, the highest yield was obtained by the farmers who utilized livestock waste in an integrated production of biogas-vermiculture-vermicomposting, which is equal to an income of IDR 1.68 million/LSU/year. The introduction of waste treatment improvement has been going on for one decade but only 30% of member farmers have adopted it. There is an associative relationship between the scale of the milk production and the farmer resistance  to practicing good waste management, meaning that there is no guarantee that larger-scale farmers participate to adress cattle-waste problems to obtain greater benefits. Hence, growing awareness to waste problem at every level of farmers needs to be continued and developed for better environment of dairy farming.

PENGARUH FAKTOR EKONOMI PADA POLA KONSUMSI: PERILAKU PEMAKAIAN BRAND SEPATU IMITASI CONVERSE DI KOTA SURABAYA
Authors: Insani Nataya Khuria , Riyanto Edi Dwi
Published: September 2024

Sepatu saat ini menjadi trend fashion, terutama di kalangan masyarakat urban. Berbagai model sepatu banyak bermunculan karena telah menjadi salah satu kebutuhan fashion yang penting sama halnya dengan busana pakaian. Dengan trend sepatu yang saat ini marak menjadikan harga sepatu mahal, apalagi brand sepatu luar negeri. Bagi orang berpendapatan tinggi, tentu tidak masalah karena bisa membelinya. Namun, bagi orang berpendapatan rendah mungkin akan berpikir ulang untuk membeli produk tersebut. Maka dari itu muncul cara alternatif untuk masyarakat kelas bawah dan menengah yang berpendapatan rendah agar bisa tetap bergaya mengikuti trend fashion yang ada. Cara tersebut adalah dengan membeli dan menggunakan produk sepatu imitasi dari merek sepatu terkenal, salah satunya ialah sepatu imitasi dari merek Converse. Munculnya sepatu imitasi ini menunjukkan bahwa saat ini masyarakat menginginkan sepatu bermerek tetapi mereka juga melihat keadaan ekonomi mereka yang seutuhnya. Penelitian ini bertujuan untuk mengetahui pola pembentukan identitas yang dimunculkan oleh para konsumen pada produk sepatu imitasi dari merek Converse dengan menggunakan teori simulakrum Jean Baudrillard. Penelitian ini merupakan penelitian deskriptif kualitatif. Lokasi penelitian ini di kota Surabaya. Penelitian ini menggunakan beberapa metode untuk pengumpulan data. Pertama observasi, yaitu dengan melakukan pengamatan terhadap subjek yang akan diteliti. Kedua wawancara, yaitu dengan melakukan tanya jawab kepada subjek yang akan diteliti. Ketiga interprestasi, yaitu memberikan pendapat maupun pandangan tentang hasil observasi dan wawancara yang telah dilakukan. Setalah itu melakukan analisis dengan mendeskripsikan dan memaknai data yang telah diperoleh. Hasil dari penelitian ini menunjukkan bahwa penggunaan produk sepatu imitasi dari merek Converse merupakan akibat munculnya konsumerisme, yakni pola konsumsi yang tidak sesuai dengan makna dari konsumsi, namun lebih mengarah pada simbol atau tanda.
KINGSTON’S THE WOMAN WARRIOR AND CHINA MEN: GENDERED CONSTRUCTION OF ABJECT THROUGH GHOSTS
Authors: Yovela Stasya , Priyatna Aquarini , Prabasmoro Tisna
Published: September 2024

The autobiographical works by Maxine Hong Kingston, The Woman Warrior: Memoirs of a Girlhood Among Ghosts (1989) and China Men (1989), portray a gendered construction of the abject through the ghosts of Kingston’s deceased family members in the novels. As Chinese descendants, the family should uphold a tradition of honoring their dead, feeding them food, and remembering them. However, Kingston’s family in the novels rejects their ghosts instead because the dead are thought to bring shame and discomfort to the family, who are now living as Americans. We see such ambiguity where the ghosts are simultaneously seen as part of the family yet also discomforting as related to the abject. By utilizing the framework of feminist narratology and theories of abjection, we see that the family abjects them by forgetting and not acknowledging them. These ghosts are part of the family but simultaneously expelled as the abject. However, despite all of the ghosts being the abject, we argue that their individual abjections vary based on their gender where the female ghosts and male ghosts are abjected differently. We argue that the abject constructed through the female ghosts is portrayed as disobedient, disturbing borders, and traumatic, whereas through the male ghosts is portrayed as passively expelled from a place of power and silenced. Despite all of the deceased being treated as outcasts, we see that the deceased women are able to reclaim subjectivity through their abjection, whereas the abjection from the male ghosts reflects ambiguity.
AMBIVALENSI BIROKRAT HINDIA BELANDA: STUDI KASUS VISI HASAN MUSTAPA AKHIR ABAD XIX
Authors: Razy Mohammad Refi Omar Ar , Munigar Muhammad Miqdad Rojab , Ma'mur Tarunasena
Published: September 2024

Penelitian ini bertujuan untuk menjelaskan transisi politik di Kesultanan Aceh pada akhir abad XIX melalui sudut pandang Hasan Mustapa. Meskipun banyak penelitian yang telah dilakukan mengenai kesulitan-kesulitan yang dihadapi Hindia Belanda dalam menaklukkan Aceh, namun masih sedikit penelitian yang mengkaji kondisi-kondisi tersebut dari sudut pandang pegawai negeri setempat. Penelitian ini menggunakan metode sejarah yang terdiri dari heuristik, kritik, interpretasi, dan historiografi. Melalui pembacaan catatan harian Hasan Mustapa, kami mencoba mengelaborasi visi Hasan dalam fase masa transisi dan pengintegrasian Aceh ke dalam wilayah Hindia Belanda. Hasan Mustapa, seorang pemuka agama dari Garut yang terkenal di Makkah karena murid-muridnya yang cendekia, diangkat sebagai Penghulu (1893–1895) di Kutaraja, Aceh, atas rekomendasi Snouck Hurgronje kepada Pemerintah Kolonial Hindia-Belanda. Ambivalensi Hasan dalam memaknai masa transisi dan integrasi Aceh yang kompleks mencerminkan kewajiban ganda untuk memenuhi tugas birokrasi kepada pemerintah kolonial Hindia Belanda sekaligus bersimpati pada perjuangan rakyat Aceh sebagai sesama Muslim. Selain itu, Sultan Muhammad Daud Syah muncul sebagai tokoh penting dalam perjuangan rakyat Aceh, yang melanjutkan perlawanan mereka dalam masa transisi dan integrasi Aceh. Meskipun banyak pemimpin dan pejabat tinggi ditinggalkan selama perang, perlawanan rakyat Aceh yang terus berlanjut menjadi tantangan yang signifikan bagi pemerintah kolonial.
Una mirada al tráfico ilícito de migrantes desde la perspectiva de “Yo capitán”
Authors: Fascioli Caorsi Federico
Published: September 2024

El presente artículo analiza la película italiana “Yo capitán” a la luz de la normativa internacional en materia de tráfico ilícito de migrantes. Se analizará el Protocolo contra el Tráfico Ilícito de Migrantes por Tierra, Mar y Aire −conocido como Protocolo de Palermo−, especialmente la definición de tráfico ilícito de migrantes cristalizada en el mismo y los hechos que surgen del largometraje. Esta galardonada película que narra el viaje de dos primos senegaleses que deciden emigrar de forma irregular a Europa se inspiró en una historia real, la de Amara Fofana: un adolescente de 15 años sin ninguna experiencia en navegación que fue seleccionado por unos traficantes para capitanear un barco con 250 personas a bordo rumbo a Europa. Es esta travesía marítima la que se tomará como eje central para desarrollar el presente trabajo académico, que –como ya se señaló– tiene como principal objetivo determinar el alcance de la definición de “tráfico ilícito de migrantes” contenida en el Protocolo de Palermo.

Authors: Song Guoyang , Han Defa , Li Yingge , He Zhaoming , Du Dongxing
Published: September 2024

In this paper, a solar tracking device that can continuously track the sun by adjusting the direction and angle of the solar panel in real time is designed and fabricated to improve the power generation efficiency of the solar cell panel. The mechanical parts as well as the automatic control part of the passive sun-tracking system are described, and the efficiency enhancement with the sun-tracking solar panel is characterized in comparison with the fixed panel system. The test results show that in the spring season in Qingdao city of eastern China, the sun-tracking system can improve the solar cell power generation efficiency by 28.5%–42.9% when comparing to the direction and elevation angle fixed system in sunny days. Even in partly cloudy days, the PV power output can increased by 37% with using the passive sun-tracking system. Economic analysis results show the cost-benefit period is about 10 years, which indicates that the passive sun tracking device can substantially contribute to the solar energy harvest practices.
Modified Cattaneo-Vernotte equation for heat transfer in solids
Authors: Mironov Victor L.
Published: September 2024

We propose a modified relation between heat flux and temperature gradient, which leads to a second-order equation describing the evolution of temperature in solids with finite rate of propagation. A comparison of the temperature field spreading in the framework of Fourier, Cattaneo-Vernotte (CV) and modified Cattaneo-Vernotte (MCV) equations is discussed. The comparative analysis of MCV and Fourier solutions is carried out on the example of simple one-dimensional problem of a plate cooling.
Unveiling the intricacies of the rice-Rhizoctonia pathosystem: a comprehensive review of host-pathogen interactions, molecular mechanisms, and strategies for sustainable management
Authors: Biswal Kumar Avinash , Das Siddhartha
Published: September 2024

Sheath blight disease in rice, induced by the necrotrophic basidiomycetes Rhizoctonia solani, has emerged as a significant menace to global rice cultivation, especially with the widespread adoption of high-yielding varieties. The pathogen’s capacity to endure unfavorable conditions and its wide host range contribute to the increased challenge for management. The occurrence of sheath blight in rice is intensified when high-yielding semi-dwarf cultivars are employed, coupled with dense planting and the application of substantial amounts of nitrogenous fertilizers. Managing this pathogen is a formidable challenge due to its broad host range, substantial genetic variability, and the absence of satisfactory levels of natural resistance in the existing rice germplasm. Due to the absence of complete resistance sources, the predominant approach for managing sheath blight has been through chemical control methods. It is imperative to explore solutions to combat this pathogen, in order to reduce rice yield losses and safeguard global food security. Developing genetic resistance provides an alternative to the use of potentially harmful chemical fungicides. This review crucially delivers efforts to enhance the understanding of the host–pathogen relationship, which involves identification of gene loci/markers associated with resistance responses, modification of host genome through transgenic approaches, examining the wide host range, epidemiology and its managemental approaches. Recent advancements and current research on the R. solani–rice pathosystem, along with a gap analysis, are presented.

При использовании подземных вод для питьевого водоснабжения поселков часто возникает необходимость в их обезжелезивании и деманганации. Вода со сверхнормативным содержанием железа и марганца неприятна на вкус, вызывает болезни сердечно-сосудистой, костной и репродуктивной систем человека. Высокая жесткость воды ведет к атеросклерозу и мочекаменной болезни. Цель данного исследования – разработка технологической схемы подготовки питьевой воды из подземных источников для водоснабжения малых населенных мест Сибири. Исследования проведены в рабочем поселке Ордынский Новосибирской области на экспериментальной установке, предназначенной для очистки природной подземной воды из скважин. В результате установлено, что предварительная аэрация и реагентная обработка воды с последующим фильтрованием на двух ступенях осветлительных фильтров, загруженных новым фильтрующим материалом «Диамикс Аква», обеспечивают питьевое качество очищенной воды. Разработана новая технологическая схема водоподготовки для питьевого водоснабжения поселка, включающая новые оборудование, материалы и реагенты, с повторным использованием промывных сточных вод и утилизацией водопроводного осадка.

When using groundwater for drinking water supply to villages, there is often a need for their deferrization and demanganization. Water with excess iron and manganese content has an unpleasant taste and causes diseases of the cardiovascular, skeletal and reproductive systems of humans. High water hardness leads to atherosclerosis and urolithiasis. The purpose of this study is to develop a technological scheme for the preparation of drinking water from underground sources for water supply to small populated areas in Siberia. The research results were obtained by conducting experimental studies. The research was carried out at an experimental installation in the working village of Ordynsky, Novosibirsk region, for the purification of natural groundwater from wells. As a result of research, it was established that preliminary aeration and reagent treatment of water followed by filtration on 2-stage clarification filters loaded with the new Diamix Aqua filter material ensures the drinking quality of purified water. A new technological scheme for water treatment for the drinking water supply of the village has been developed, including new equipment, materials and reagents, with the reuse of rinsing wastewater and disposal of water sludge.

В статье приведены результаты апробации модифицированного кремнеземистого компонента в сравнении с базовым кремнеземистым компонентом. Актуальность работы обусловлена совершенствованием технологии путем максимально полного использования потенциала исходного сырья и активации его внутренних резервов. Доказана возможность регулирования реологии ячеистобетонной смеси на этапе формирования структуры. Показаны изменения размера и объема пор, а также их количества по видам пористости. Анализ образцов после тепловлажностной обработки выявил различия в дисперсности и морфологии поверхности новообразований. На основании полученных данных выявлены причинно-следственные связи и показаны пути повышения качества газобетона. Для марки по средней плотности D600 при использовании литьевой и ударной технологий производства установлено: увеличение коэффициента конструктивного качества с 8,67–8,98 до 9,46–9,57; снижение отпускной влажности с 24,9–20,5 до 22,2–17,3%; уменьшение теплопроводности с 0,153–0,154 до 0,144–0,150 Вт/м∙оС; увеличение паропроницаемости с 0,171–0,175 до 0,186–0,195 мг/(м∙ч∙Па); сокращение усадки при высыхании с 0,149–0,104 до 0,133–0,102 мм/м соответственно. В результате раскрыт высокий потенциал применения модифицированного кремнеземистого компонента для решения практических технологических задач.

The study presents the results of approbation of the modified silica component and comparison with the basic silica component. The relevance of the work is due to the improvement of technology due to the fullest possible use of the potential of the feedstock and the activation of its internal reserves. The possibility of regulating the rheology of a cellular concrete mixture at the stage of structure formation is proved. Changes in the size and volume of pores, as well as their number by type of porosity, are shown. The analysis of samples after heat and moisture treatment revealed differences in the dispersion and morphology of the surface of neoplasms. Based on the data obtained, the authors established causal relationships and demonstrated ways to improve the quality of aerated concrete. For the D600 medium density brand, when using injection molding and impact production technologies, it is established: an increase in the coefficient of structural quality from 8.67–8.98 to 9.46–9.57; a decrease in the release humidity from 24.9–20.5% to 22.2–17.3%; a decrease in thermal conductivity from 0.153–0.154 to 0.144–0.150 W/m∙oC; an increase in vapor permeability from 0.171–0.175 to 0.186–0.195 mg/(m∙h∙Pa); reduction of shrinkage during drying from 0.149–0.104 to 0.133–0.102 mm/m, respectively. Thus, the study reveals the wide potential of using a modified silica component to solve practical technological problems.

Published: September 2024

Background: Phelan-McDermid syndrome (PMS) [OMIM: 606232] is a neurodevelopmental disorder commonly due to a deletion of chromosome 22q13.3. It is characterized by neonatal hypotonia, severely delayed absenting speech, developmental delay, and minor dysmorphic facial features.
Case Presentation: The Comparative genomic hybridization array was performed on three patients referred to our genetics department for an autism spectrum disorder and facial dysmorphia. The results showed a deletion of chromosome 22.
Conclusion: In summary, the genotype-phenotype of PMS is still not clear. Moreover, the penetrance of this deletion seems to be incomplete for some genes, leading to variable phenotypes in patients with the same deletion.

Diagnostic tests for primary immunodeficiency disorders: Classic and genetic testing
Authors: Klangkalya Natchanun , Fleisher Thomas A. , Rosenzweig Sergio D.
Published: September 2024

Primary immunodeficiency diseases encompass a variety of genetic conditions characterized by a compromised immune system and typically results in increased susceptibility to infection. In fact, they also manifest as autoimmunity, autoinflammation, atopic diseases, and malignancy. Currently,
the number of recognized monogenic primary immunodeficiency disorders is set at ∼500 different entities, owing to the exponential use of unbiased genetic testing for disease discovery. In addition, the prevalence of secondary immunodeficiency has also been on the rise due to the increased
use of immunosuppressive drugs to treat diseases based on immune dysregulation, an increase in the number of individuals undergoing hematopoietic stem cell transplantation, and other chronic medical conditions, including autoimmunity. Although the clinical symptoms of immunodeficiency disorders
are broad, an early diagnosis and tailored management strategies are essential to mitigate the risk of infections and prevent disease-associated morbidity. Generally, the medical history and physical examination can provide useful information that can help delineate the possibility of immune
defects. In turn, this makes it feasible to select focused laboratory tests that identify immunodeficiency disorders based on the specific immune cells and their functions or products that are affected. Laboratory evaluation involves quantitative and functional classic testing (e.g., leukocyte
counts, serum immunoglobulin levels, specific antibody titers in response to vaccines, and enumeration of lymphocyte subsets) as well as genetic testing (e.g., individual gene evaluation via Sanger sequencing or unbiased evaluation based on next-generation sequencing). However, in many cases,
a diagnosis also requires additional advanced research techniques to validate genetic or other findings. This article updates clinicians about available laboratory tests for evaluating the immune system in patients with primary immunodeficiency disorders. It also provides a comprehensive list
of testing options, organized based on different components of host defense.
