Authors: Horikoshi Ryo , Endo Yota , Shirotani Dai , Nakanishi-Masuno Tsugumi , Shioyama Hiroshi 
Published: June 2024

Abstract
The conversion from line-angle formula to chemical formula often poses a challenge for first-year nonchemistry majors. To address this, the authors developed an engaging exercise lecture that encompasses the conversion process and related chemistry concepts, including molecular weight and elemental analysis. Initially, the instructor reviews basic chemistry concepts with the students. Subsequently, students construct a NanoKid structure model using transistors and red LEDs connected by plastic tubes, representing carbon and oxygen atoms, respectively. By referencing their models, students identify the chemical formula of NanoKid, calculate its molecular weight, and perform elemental analysis under the guidance of the instructor. Additionally, they estimate the scale of the NanoKid model relative to the actual NanoKid molecule. The exercise promotes peer review among students and is completed within approximately 45 min. A post-lecture questionnaire revealed that the exercise was well-received by the students.
Universities and Firm Performance: Evidence from Germany
Authors: Meier Philipp 
Published: June 2024

AbstractThis paper analyses the impact of universities on firm performance based on the universe of firms in Germany from 2013 to 2017. From a regional perspective, firms have 0.92 % more revenues per employee in counties with a university than in a county without a university. To address potential endogeneity concerns, I focus on a subsample of universities, founded for political reasons. Analysing different types of German universities indicates that the high-skilled regional labour supply is important for the positive impact of universities, while proximity to the knowledge spillovers of research-intensive universities is associated with weaker firm performance. The latter finding is at least partially explained by the networks of multinational firms.
Immobilisation of catalase purified from mushroom (Hydnum repandum) onto glutaraldehyde-activated chitosan and characterisation: Its application for the removal of hydrogen peroxide from artificial wastewater
Authors: Tabaru Işıl Nur , Türkhan Ayşe 
Published: June 2024

Abstract
Hydrogen peroxide (H2O2) is a chemical that is widely used in many industrial processes, and, except at certain concentrations, it is toxic in biological systems such as water and air. Among enzymes, catalases are important industrial enzymes because of their role in the conversion of hydrogen peroxide to water and molecular oxygen. Herein, catalase (CAT) from Hydnum repandum was purified 3.02-fold with a yield of 68.10% by three-phase partitioning (TPP) for the first time. The purified catalase was immobilised on glutaraldehyde-activated chitosan (Glu-Cts), and its applicability for the removal of hydrogen peroxide released from industrial processes was investigated. The results of the present study showed that the optimum pH and temperature were found to be 7.0 and 30°C for both free and immobilised catalase (CAT-Glu-Cts). The catalytic efficiency (V
max/K
m) of the immobilised enzyme increased 8-fold compared to the free enzyme. CAT-Glu-Cts was shown to have better pH, thermal stability, and storage stability than free CAT. In this study, >96% of 6 mM, 15 ve 24 mM H2O2 was removed from artificial wastewater after 2 h using immobilised catalase. We expect that CAT-Glu-Cts, obtained by purifying a plant-derived catalase and immobilising it into an environmentally friendly and biocompatible material, is a promising candidate that can be safely used for H2O2 removal in various branches of industry.

Abstract
This scoping review provides an up-to-date overview of the evidence on adolescent and youth-friendly health services (AYFHS) in sub-Saharan African countries. We conducted a search of four databases and grey literature sources to identify English language publications from January 1, 2005, to December 14th, 2022. The review synthesized evidence on the models and characteristics of AYFHS, the application of World Health Organization (WHO) standards, and whether AYFHS have improved young people’s health outcomes. In total, 77 sources were included in the review, representing 47 AYFHS initiatives spanning 19 countries, and three multi-country reports. Most commonly, AYFHS were delivered in public health facilities and focused on sexual and reproductive health, with limited application of WHO standards. Some evidence suggested that AYFHS increased young people’s health service utilization and contraceptives uptake. There is a clear need to strengthen and develop innovative and multi-pronged approaches to delivering and evaluating AYFHS in this region.
MZM–SOA based RoF system for 30-tuple millimeter-wave generation
Authors: Kumar Ajay , Kedia Deepak , Singla Shelly 
Published: June 2024

Abstract
In this paper, we have reported radio over fiber system with 30-tuple millimeter-wave generation using dual parallel Mach–Zehnder modulator and semiconductor optical amplifier. The optimum choice of Mach–Zehnder modulator parameters has resulted into generation of signal lightwave and pump signal with frequency separation of 10f
RF. Four wave mixing effect in semiconductor optical amplifier results into 30-tuple millimeter-wave signal. The proposed scheme is applicable to radio over fiber system with multiple base stations. The multiple number of frequencies such as 50 GHZ, 100 GHz, and 150 GHz have been generated using 5 GHz radio frequency only. NRZ data at 2.5 Gbps was modulated and successfully transmitted via optical fiber. The impact of injection current on the sideband ratio and BER is investigated. The proposed scheme confirms quality reception of demodulated signal at a transmission distance of 20 km.
Cancer nuclear envelope rupture and repair in taxane resistance

Published: June 2024

Abstract
Taxanes, including paclitaxel, docetaxel, and cabazitaxel, are key agents in cancer treatment, often used as front-line chemotherapy drugs in combination with other agent(s) (commonly carboplatin) and as second-line treatments alone. Generally, taxanes are highly effective, but drug resistance unavoidably develops following repeated treatment. Taxanes work by binding to and stabilizing microtubules, leading to mitotic arrest, mitotic catastrophe, and micronucleation. The long-recognized mechanisms of drug resistance generally can be classified into three categories: drug efflux, microtubule polymerization, and apoptotic pathway. A recent new addition to this list is a mechanism related to the nuclear envelope, as cancer cells undergo micronucleation and nuclear membrane rupture when treated with taxanes. All these mechanisms may operate simultaneously as taxane resistance is multi-factorial. Here, we review the cell biology understanding of nuclear envelope breaking in production of micronucleation, and nuclear membrane rupture and repair, and propose that these processes are involved in taxane resistance.
Thermal radiation forces on planar structures with asymmetric optical response
Authors: Deop-Ruano Juan R. , García de Abajo F. Javier , Manjavacas Alejandro 
Published: June 2024

Abstract
Light carries momentum and, upon interaction with material structures, can exert forces on them. Here, we show that a planar structure with asymmetric optical response is spontaneously accelerated when placed in an environment at a different temperature. This phenomenon originates from the imbalance in the exchange rates of photons between both sides of the structure and the environment. Using a simple theoretical model, we calculate the force acting on the planar structure and its terminal velocity in vacuum, and analyze their dependence on the initial temperature and the geometrical properties of the system for different realistic materials. Our results unravel an alternative approach to manipulating objects in the nano and microscale that does not require an external source of radiation.

Published: June 2024

Abstract

Purpose
The distinction between beliefs and facts, as well as between science and pseudoscience, appears to be hazy in the post-truth era. This study draws inspiration from public discourse concerning the safety of COVID-19 vaccines during the pandemic, aiming to explore the narratives of COVID-19 vaccine skeptics within the Greek online public sphere.

Methodology
For the purposes of our study, we analyzed Facebook posts from users’ pages and public groups during a three-month period (from September 2021 to November 2021), focusing primarily on content related to COVID-19 vaccination. By employing thematic analysis, we investigated the main themes upon which the anti-vaccination camp bases its rhetoric and the sources it uses to justify its claims.

Findings
Our findings suggest that in the Greek online context, the anti-vaccination discourse, as expressed on Facebook platform, is an amalgam of distrust towards institutional actors (politicians, the medical community, legacy media, the establishment in general) and concerns regarding the safety/complications of COVID-19 vaccination itself.

Social implications
Our study contributes to the existing body of academic literature addressing the impact of social media platforms on public opinion related to health matters. It underscores the potential and challenges associated with the unregulated dissemination of information within polarized digital contexts.

Originality/value
This study sheds light on the distinctive characteristics of anti-vaccine rhetoric, as expressed on social media, within the context of Greek society. It offers insights to scholars and researchers interested in the dynamics of social media discourse and its implications for public health communication.

Authors: Sonule Bhavna , Mehetre Nikhil , Kumar Lalit 
Published: June 2024

Abstract
Dietary polyphenols from plant sources play an important role in the human diet. They have various biological effects, such as protein kinase inhibition, antibacterial, anticancer, antiulcer, antiarthritic, and anti-angiogenic properties. Among the various phenolic chemicals found in plants, resveratrol (trans-3,5,4′-trihydroxystilbene) (RVT) is a non-flavonoid polyphenolic compound that has been extensively studied for its health-promoting advantages, including its anti-cancer, neuroprotective, anti-inflammatory, antioxidant, and cardio-protective activities. Considering its potential in pharmaceutical nanoformulations, a rapid, economical, sensitive, and robust UV spectrophotometric method was developed and validated. The proposed method was developed in phosphate buffer at pH 7.4 to estimate the RVT content in the pharmaceutical nanoformulation. The method was developed at a reported wavelength of 306 nm. The developed method was validated according to ICH Q2A (R1) guidelines and was applied for the estimation of RVT in prepared nanoformulations. The method showed exceptional linearity in the range of (1–6) μg mL−1 with a coefficient of determinant value of 0.9998. The study proves that the developed method is linear, precise, sensitive, robust, reproducible, and accurate. This method can be applied for the estimation of RVT in nanoformulations and other bulk dosage forms.
Raum und Rhythmus: Radio-Design im Diskurs der Zeitschrift Innendekoration in den 1920er und 1930er Jahren
Authors: Zeising Andreas 
Published: June 2024

Abstract
From the mid-1920s onward, radio, which in its early days had still been experimental in many respects, became a companion of everyday life. The professionalization of program content was accompanied by a change in the appearance of the radio itself: simple receivers with headphones were replaced by elegant radio furniture with a modernist touch meant to blend in with contemporary home design. The interior magazine Innendekoration, published by Alexander Koch in Darmstadt, commented on the integration of the Zeitgeist medium radio into the private interior in a number of essays that present radio as a technological interface between the private and the public sphere, individuation and the masses, location and the dissolution of boundaries.

Domestic violence spans across cultures and many countries include Indonesia. In the women and children perspectives, it is taboo to report the domestic violence because it is a private matter, not for the public domain. Therefore domestic violence screening through the empowerment and mentoring of mental health cadres is needed to raise awareness of domestic violence in rural community. The aim of this study is to explore the influence of the empowerment and mentoring of mental health cadres on screening domestic violence. A quasi experimental was conducted among mental health cadres. The total sampling derived from six sub district of Kalegen village. Data were analyzed by using SPSS (version 19). A total sample of 22 mental health cadres aged between 28 years to 49 years. There is a high significant screening capability in pretest-posttest after empowerment andÂ mentoring of mental health cadres (p .001). The empowerment and mentoring of mental health cadres on screening domestic violence could strengthen support and raising domestic violence awareness. This intervention should become a part of community health program in community. A longitudinal study can be carried out to prevent domestic violence.

Obesity has become a pandemic in the Asia-Pacific region, with an alarming rate of increase in the prevalence of obesity. The impact of obesity and its associated comorbidities goes beyond the healthcare system, posing a substantial burden not only on the individual, but also on the society and the economy. In this review, we focus on the latest situation in the Asia-Pacific region, and review the diagnostic criteria of obesity, management strategies and access to treatment in the region. National guidelines on obesity management are available in some countries, reflecting the recognition of the problem of obesity by healthcare professionals and government bodies. Although a range of anti-obesity pharmacotherapies and bariatric surgeries are available, access remains restricted and reimbursement criteria vary in different parts of the Asia-Pacific. Prevention is key, as treatment alone cannot reverse the tide of obesity, and a sustained partnership between the patient and the clinician is necessary to manage the chronic disease of obesity.

Authors: Davis Joseph , Atkins Chelsea , Doyle Michael , Williams Carl , Boyce Ross , Byrd Brian 
Published: June 2024

Background La Crosse virus neuroinvasive disease (LACVND) is the most common cause of arboviral encephalitis in children within the United States; in North Carolina, it is the most prevalent endemic mosquito-borne disease in humans. Methods Here we report a surveillance summary of confirmed and probable LACVND during 2000–2020 using North Carolina Electronic Disease Surveillance System data, and we describe associated demographic characteristics, spatiotemporal distribution, clinical features, and mortality rates. Results A total of 355 cases (74.9% confirmed) were reported from 41 North Carolina counties; most cases (92%) occurred in 19 Western North Carolina counties. An average of 17 cases were reported annually with the majority (94%) of cases occurring between mid-June and early October (epiweeks 25–41). The median case age was nine years (range: 1–95 years), 79% were aged ≤ 18 years, and 56.6% were male. Cases commonly presented with headache (95.4%), fever (95.1%), and altered mental status (80.8%); encephalitis (82.0%) and meningitis (45.9%) were frequently diagnosed. Encephalitis was more common in children (87%) than adults (62%) (P < .001). Similarly, seizures were more common in children (54%) than adults (27%) (P < .01). The case fatality rate was 1.4%; however, differences in age-specific rates were observed. Limitations Changes in case definitions and reporting requirements, missing data, different reporting sources, and the retrospective nature of this study are all important limitations of our study. Conclusion Given the persistent endemicity of La Crosse virus in Western North Carolina, clinicians and public health providers should consider La Crosse virus disease in all individuals, especially children, with compatible symptoms and a travel history to endemic counties. Prevention measures and educational outreach/public health messaging should focus on caregivers and children in Western North Carolina counties and during times when transmission risk is higher (i.e., summer and early fall).
Forecasting the development indicators of oil and gas reservoirs based on initial period data

Published: June 2024

The practice of oil fields development indicates that the economic efficiency of this process is largely determined by the oil production regime, which is characterized by indicators of the intensity of hydrocarbon extraction: the total number of wells in the field, the dynamics of their commissioning, and production volumes from each of them. At the same time, when justifying oil production projects, it is a very common opinion that it is premature to address the problems of managing the rate of raw material selection in the early stages of project development, often relegated solely to petroleum engineering without consideration of economic aspects. This often leads to a decrease in the efficiency of the entire project due to the inability to control the oil production regime in later stages. This formulation of the problem is particularly relevant for new oil production regions. In well-studied oil and gas region, an error in selecting the rate of raw material production may not be so critical. However, in the case of new fields in undeveloped regions, the cost of such an error can significantly exceed the economic benefits derived from the sale of all the oil produced. In this regard, the problem of developing models and methods for determining economically feasible regimes for oil field development based on controlling the rate of product selection is relevant. The article predicts the dynamics of the following indicators of oil and gas field development: current and cumulative production of oil, water and gas, average well flow rate, and water cut depending on the number of production wells, etc. It demonstrates how it is possible to simplify two- and three-parameter models using the proposed forecasting technique.
Methods for solving two-dimensional tasks of cutting raw materials

Published: June 2024

The article discusses the methodology for solving two-dimensional material cutting problems, widely used in practice and applied to industrial equipment. Several modifications of the original problem are considered. An interactive optimization procedure is presented for a general two-dimensional material cutting problem. When cutting correctly, the two dimensions of the cut pieces (usually length and width) must be consistent with the length and width of the sheet. One of the problems most frequently encountered in literature and in practice is the problem of cutting a rectangular material into rectangular pieces. Therefore, this work focuses on this task. First, a two-dimensional problem of cutting material is formulated. Next, methods for solving the problem of cutting material and the related problem of constructing (creating) a template is outlined. The solution method includes a new interactive (dialogue) optimization procedure. A very interesting feature of 2D problems is that there are different options that arise from practical requirements due to the type of material and manufacturing process constraints. A description of the general technique would be incomplete without mentioning how it can be modified to apply specific practical problems. Therefore, the paper briefly discusses some practical applications and describes ways to modify the general methodology to solve these practical problems.
