Fotografia chłopska w zakładach fotograficznych w okresie transformacji. Na podstawie książki „Dworki i pałace” oraz czasopisma branżowego „Twoje Studio”
Authors: Myślińska Małgorzata
Published: May 2024

W ramach rezydencji w Centrum Kultury Zamek w Poznaniu i projektu Zakład Fotograficzny (2018) przeprowadziłam inwentaryzację wyposażenia wielkopolskich zakładów fotograficznych: przede wszystkim teł wykonywanych przez malarzy rzemieślników oraz rekwizytów. Na jej podstawie, wspólnie z kolektywem wydawniczym Ostrøv opracowałam książkę fotograficzną Dworki i pałace.
Artykuł poświęcony jest kulturze wizualnej odwiedzonych przeze mnie zakładów fotograficznych, czasopismu branżowemu „Twoje Studio”, a także sesjom scenkowym, w których brały udział tła i rekwizyty. Badam wytwarzaną za ich pomocą tożsamość — szlacheckie imaginarium posiadającej chłopskie korzenie i aspirującej do lepszego życia fantomowej klasy średniej. Wcielanie się do nowej grupy społecznej odbywało się zgodnie z panującymi wówczas normami widzialności — na drodze naśladowania, gdzie rolę tak zwanej konwencji przebieranki odgrywały między innymi sesje scenkowe inspirowane kulturą arystokratyczno-ziemiańską. Wizerunki wytwarzane za pomocą teł, rekwizytów, choreografii i gestów miały legitymizować nową pozycję społeczną, pomagać w pięciu się w górę po drabinie społecznej.
Korzystając z narzędzi radykalnego programu socjologii wizualnej — kategorii patrzenia „przez” oraz „za” zdjęcie — pokazuję, że fotografię związaną z kulturą wizualną zakładów fotograficznych można zaliczyć do fotografii chłopskiej. Jedną z jej cech jest niemożliwość zaprzeczenia, że czegoś nie było, że ktoś nie istniał. Fotografia chłopska, której najważniejszą cechą było upamiętnienie, służyła, jak udowadniam, silnemu zapominaniu: wspólnych korzeni — chłopskiej genealogii.

SINERGI FINTECH DENGAN PERBANKAN SYARIAH DALAM PERSPEKTIF HUKUM
Authors: Ahmad Syafii Andi Fariana
Published: May 2024

Abstract: The digital era that cannot be stifled by its development has a negative and positive impact on humans in all dimensions of life. However, this important development should be used as an opportunity and challenge to provide benefits and convenience.Similarly in the financial industry, where the development of information technology has penetrated and entered all financial sectors, including the banking industry. Islamic banking that carries Islamic values must also participate and utilize this phenomenon and collaborate with Fintech (Financial Technology) for the purpose of benefit, and this is very possible to be done while upholding the values of sharia. For this reason, regulation is indispensable so that collaboration that is carried out will result in comfort, tranquility and most importantly, emphasizes that compulsory avoidance from transactions that are Ribawi, Gharar, Maysir, Tadlis, Risywah and Israf and transactions on objects that are haram or immoral. OJK as a regulator and supervisor in the financial industry has issued regulations relating to this matter, and supported by the DSN-MUI Fatwa, while it is considered currently as adequate, other legal products are needed to anticipate the development and utilization of IT in the Islamic finance industry, especially Islamic Banking in the future.
Abstrak: Era digital yang tidak bisa dibendung perkembangannya memberikan dampak negatif dan positif bagi manusia dalam semua dimensi kehidupannya. Namun, perkembangan yang niscaya adanya ini selayaknya dijadikan peluang dan tantangan untuk memberikan keuntungan dan kemudahan. Demikian pula dalam industri keuangan dimana perkembangan teknologi infomasi merambah dan masuk kesemua sektor keuangan termasuk juga industri perbankan. Perbankan syariah yang mengusung nilai-nilai syariah juga harus ikut dan memanfaatkan fenomena ini serta berkolaborasi dengan fintech (financial technologi) untuk tujuan kemaslahatan, dan hal ini sangat mungkin dilakukan dengan tetap menjunjung tinggi nilai-nilai syariah. Untuk itu regulasi sangat diperlukan agar kolaborasi yang dilakukan melahirkan kenyamanan, ketenangan serta yang paling utama tetap menekankan bahwa wajib terhindar dari transaksi yang ribawi, gharar, maysir, tadlis, risywah dan israf dan transaksi atas obyek yang haram atau maksiat. OJK sebagai regulator dan pengawas dalam industri keuangan telah mengeluarkan Peraturan yang berkaitan dengan hal tersebut, dan didukung dengan Fatwa DSN-MUI maka sementara dirasa cukup memadai namun kedepan diperlukan produk-produk hukum lain untuk mengantisipasi perkembangan dan pemanfaatan IT dalam industri keuangan syariah khususnya Perbankan Syariah.
RELEVANSI EFISTEMOLOGI MASLAHAH NAJAMUDDIN AT-TUFI DALAM ISTINBATH HUKUM ANAK SEBAGAI MAHKUM ALAIH
Authors: Mansyur Zaenudin
Published: May 2024

Abstract: This paper investigates the relevance of epistemological principles of maslahah initiated by at-Thufi in determining children as mahkum alaih particularly in contemporary muamalah transactions. At-Thufi is consistent with his principle of prioritizing maslahah instead of nash or ijma’ with no beneficial factors since maslahah and mafsadah cases in legal matter can be determined by independents or authorities and Ijma’ cannot become justifying tool for reasoning. His unique statement is extremely relevant to the children’s status as mahkum alaih in contemporary muamalah transactions, namely transaction is within muamalah boundary therefore it is legitimate for under age children  to undertake transactions due to their reasoning. Moreover, the purposes or benefits intended are the education to maturate children to carry out transactions and to provide facilitation to do so without leaving the home which are relevant to maslahah initiated by at-Thufi. Furthermore, the relevance of at-Thufi’s thought is not limited to that reasoning authority is prioritized instead of nash` dan ijma`, for instance, child’s reasoning ability is of more importance than waiting for the age of 17 and 18. Similarly, online transactions that are inevitable trends or habits for children in the contemporary age are extremely relevant to at-Thufi’s view that benefits founded by reasoning only work within the boundary of customary traditions.
Abstrak: Makalah ini mengakji tentang relevansi prinsip efistemologi maslahah yang digagas at-Thufi dalam penetapan anak sebagai mahkum alaih terutama dalam transaksi muamalah kontemporer. At-Thufi tetap dalam pendiriannya memenangkan maslahah daripada nash atau ijma`yang tidak ada unsur kemaslahatan di dalamnya karena perkara maslahah dan mafsadah dalam soal hukum dapat ditentukan oleh independen atau otoritas akal. Nash dan ijma` tidak bisa menjadi alat konfirmasi terhadap akal. Statemennya yang unik ini sangat relevan dengan status anak yang dijadikan sebagai mahkum alaih dalam transaksi muamalah kontemporer, yaitu transaksi merupakan wilayah muamalah maka anak yang dibawah umur sah-sah saja melakukan transaksi karena kemampuan akal yang dimilikinya. Apalagi tujuan atau kemaslahatan yang dihajatkan adalah edukasi dalam mendewasakan anak untuk melakukan transaksi serta memberikan keringan dalam melakukannya tanpa harus keluar rumah tentu sangat relevan dengan maslahah yang digagas at-Thufi, yaitu menetapkan tujuan lebih penting daripada sarana dalam istinbath hukum. Selanjutnya relevansi pemikiran at-Thufi ini tidak terhenti ketika menyatakan otoritas akal lebih dimenangkan daripada nash` dan ijma`, misalnya kemampuan akal anak lebih penting daripada menunggu usia sampai 17 dan 18 tahun. Begitu juga dalam aktivitas transaksi one line merupakan trend atau kebiasaan yang tidak bisa dihindari oleh anak zaman kontemporer tentu sangat relevan dengan pandangan at-Thufi bahwa kemaslahatan yang diprakarsai oleh akal hanya berlaku dalam wilayah adat kebiasaan.

Published: May 2024

Introduction: The mineral ore processing industry is a sector that can generate pollutants in the form of dust during the production, commonly known as respirable dust. This dust can enter the upper respiratory tract and lungs, thereby causing health problems to employees working in the mineral ore processing industry. This study aims to investigate health risks associated with exposure to dust in the mineral ore processing industry. Methods: Environmental Health Risk Analysis (EHRA) was used to assess dust exposure over the previous three years, following the NIOSH Manual of Analytical Methods (NMAM) 0600 for dust sampling measurement. Results: Seven locations with high dust emissions were considered for this study. The results of the respirable dust sampling showed that the concentrations in the previous three years ranged from 1,823 to 6,109 mg/m3, followed by a decrease in the following year to 0.049 to 2,715 mg/m3. Meanwhile, in the final year, the concentration of respirable dust ranged from 0.094 to 1.341 mg/m3. The calculated risk quotient (RQ) value for the previous three years remained below 1, indicating safety. Conclusion: Athough respirable dust was considered safe in the previous year, it is important to constantly control exposure due to continued high levels and the possibility of future increases

Authors: Qu Qiang , Chen Zhuo , Sun Guo-Tao , Qiu Ling , Zhu Ming-Qiang
Published: May 2024

The low performance of electrode materials is the main obstacle limiting the development of the supercapacitor industry, which can be solved by doping cobalt ferrate nanoparticles (NPs) with carbon materials. Herein, the composites of CoFe2O4 based on activated carbon (AC) were successfully prepared using a one-step solvothermal method and subsequently applied in anodes of battery-type asymmetrical supercapacitors. The effect of solvothermal temperature and heating time on the composite characteristic was systematically evaluated. The electrochemical analysis in the three-electrode system revealed that modified activated carbon heated at 140 °C for 24 h (140MAC24) displayed excellent specific capacitance of 571.36 F/g at the current density of 0.2 A/g due to the synergistic effect of the double-layer and faradic capacitance. Moreover, iron and cobalt elements in CoFe2O4 could change into the oxide form to accelerate charge in potential range window of -1.0 to -0.2 V and discharge from -0.2 to 0.2 V, respectively. Meanwhile, the result of assessing economic feasibility suggested the splendid availability of 140MAC24 electrodes. Additionally, the assembled supercapacitor displayed the outstanding specific capacitance of 171.31 F/g in the potential window of 1.8 V, energy density of 43.5 Wh/kg at the current density of 0.2 A/g, and capacitance retention rate of 82.49% after 10,000 cycles. The excellent electrochemical properties demonstrated that CoFe2O4 could be used as a bifunctional agent for enhancing supercapacitive performance.

Published: May 2024

Osteochondral injuries represent prevalent clinical conditions with profound implications for functional impairment and diminished quality of life. Despite the considerable potential of tissue engineering in osteochondral repair, substantial strides in clinical implementation remain elusive. Biomimetic materials, designed to emulate natural cartilage, offer a stabilized structure and microenvironment capable of accommodating the diverse properties inherent in different cartilage regions. Smart materials, endowed with the ability to deliver drugs, metal ions, and growth factors contingent on the disease progression, exert precise control over the microenvironment and cellular epigenetic behaviors. This review scrutinizes the nuanced characteristics of cartilage in both physiological and pathological states. Subsequently, a succinct overview of recent applications of biomaterials with bionic and smart attributes in osteochondral regeneration and repair is provided. Finally, we propose our perspectives on the application of biomimetic-smart materials in osteochondral regeneration and repair, emphasizing their potential clinical translation.

Published: May 2024

Spray drying is one of the widely used drying process in chemical, pharmaceutical, and food industry. This process allows removing water from the product, which is produced in the solution form, and turn the finished product into a flowing powder material. It is obvious that such a process requires a significant amount of thermal energy, which is spent on the water evaporation. In addition, as in any drying process, in spray drying there is a problem with possible material over-drying. Therefore, the task of qualitative regulation of the spray drying process remains relevant.
In this article, we attempt to compare the efficiency of two modern controllers for controlling the spray drying process. This is known in the theory of control of dynamic objects using predictive models model predictive controller and a fuzzy controller based on linguistic variables. The regulators choice due to both their popularity and high control quality indicators, which are given in published scientific works. The study was performed on based on spray drying process models, which were obtained in the previous work of the authors.
In the research we used the software package MATLAB Simulink for control systems simulation. The research result show, that using the MPС-controller in the spray dryer’s control system allow to reduce the transient processes time. However, in case of a fuzzy controller, the control system partially levelling the mathematical model’s inaccuracy.

This study, conducted with meticulous attention to detail, comprehensively examines the state of plants and their adaptation to Kazakhstan's extra-arid climatic zone of the Mangistau. It uses the collections of woody plants from the Mangyshlak Experimental Botanical Garden in Aktau as a case study and extrapolates the results to the entire region. The study area is arid and unsuitable for many plants, so examining physiological adaptation mechanisms and strategies for preserving plants in unfavourable conditions is crucial. The study employed a range of methods, including the measurement of the intensity of transpiration, leaf hydration, and the content of chlorophyll A, B, and carotenoids. These methods were chosen for their proven effectiveness in similar studies and their ability to provide accurate and reliable data. The samples were also assessed using a point system for resistance to drought, phytophagy, gas tolerance, salt tolerance, winter hardiness, and soil fertility. The results obtained and entered into the IEBG platform “DinTseR” to assess the value of the introduction using a diagnostic scale revealed a high variability (up to 51.7-52.2%) of physiological indicators of growth and development. The highest values of transpiration intensity were observed in deciduous trees and shrubs, rose varieties (205-243 mg/g fresh leaf mass per hour), leaf water content - in climbing plants (68.9%), chlorophyll A and B content - in deciduous plants, and plants - old trees, fruit trees and varietal roses (3.46-3.93 and 1.34-1.84%). Their concentration in coniferous species is almost two times lower (0.63%). A correlation was also made between various significant factors. Twenty regression equations and forecasts have been identified that can be used to diagnose and assess resistance, thereby reducing the cost of determining the introduction value in the conditions of Mangistau. These findings are essential in understanding and preserving the unique flora of the Mangistau region.

Authors: Palacios Merino Luis Alberto , Mauricio Sanchez David Santos
Published: May 2024

With the Sendai Framework (2015-2030) and the Paris Agreement (2015), the UN has been promoting at a global level, the priority objectives to protect the life and well-being of people, these documents of global consensus have scheduled in several countries, an extensive list of actions of responsibilities and commitments to the environment, to address natural disasters among those of greatest impact earthquakes and floods and among earthquakes (seismic activity). The materialization of the disaster is a natural or human-induced event, it manifests itself in permanent changes in society and by its origin it is classified as natural, anthropogenic (anthropogenic) and mixed, creating a worldwide problematic situation of immediate reaction. The attention and alert in the scientific community have been adding efforts, but in a disorganized way, with limited human and material resources and with globalized strategies still to be improved. The literature review of disaster risk management due to seismic activity, from 2008 to 2023, allows us to have updated information to identify the factors and deepen them, with the understanding, comprehension, and multidisciplinary knowledge. The selected researches that mention the factors (elements) that influence risk management of natural disasters due to seismic activity (RMNDDSA) allow us to know the advances and spaces to approach them, which constitutes the motivation to study the twenty-four (24) factors present in this type of disasters. The selected research articles indicate important advances that associate disaster risk management (DRM) and communication technology (ICTs). The technological means mentioned are well received and accepted by society, capable of detecting and communicating in real time seismic activity worldwide, with the help of social mobile networks, technological platforms, Twitter, Facebook, and others.
Mitigating Overfitting in Neural Net Classification of Radio Galaxies through Wavelet Analysis
Authors: Liu Andrew , Sabhanayakam Karthik
Published: May 2024

Over the last few decades, advancements in astrophysics have been closely linked to the development of powerful machine-learning models that can accurately classify celestial bodies. At the same time, however, many astronomical datasets are filled with new features collected by increasingly powerful telescopes. These features can cause overfitting, clouding predictive abilities, and dampening the ability of many models to classify images. Therefore, motivation to design more efficient models has skyrocketed—aiming to optimize for lower run times and high accuracies, even with fewer provided features. In our project, we seek to optimize a convolutional neural network model using a technique known as wavelet analysis. This technique allows us to pick the key features of an astronomical image and accentuate niche details, saving time and boosting accuracy. We applied it to the MiraBest Dataset, a dataset compiled from the FIRST sky survey using a virtual telescope. In the end, after training our neural network on the original images and the five filters (approximation, horizontal, vertical, diagonal, and combined), we found that with fewer features and less overfitting, the vertical Daubechies-family wavelet filter outperformed the original runs with the unaltered images by over 10%. Our findings suggest that wavelet analysis can help harvest the most valuable features in images of celestial bodies–leading to enhanced predictions in astronomical applications and perhaps bolstering modern astrophysical theory.

Authors: Aoki,* Takuma , Miyamoto Takashi , Kizaki Kota , Ueshima Asuka , Iwasaki Kentaro , Kusaka Takuya , Terui Haruko
Published: May 2024

: We report the case of a 2-year-old Norwegian Forest cat diagnosed with pulmonary edema and pulmonary hypertension (PH) secondary to cor triatriatum sinister, who showed improved breathing following furosemide treatment. Sildenafil was prescribed post-discharge without diuretic. Thirty-eight days later, no abnormalities were observed in the septum or accessory chamber of the left atrium; however, continuous mosaic blood flow (maximum velocity, 3.14 m/s) was observed in two enlarged pulmonary veins. Pulmonary artery enlargement (main pulmonary artery to thoracic aorta ratio: 1.90), pulmonary vein stenosis (PVS), and diffuse bilateral ground-glass lung opacities were observed using computed tomography. PH with partial PVS and pulmonary parenchymal disease was diagnosed. The cat was further treated with furosemide with no clinical symptoms, but succumbed to acute dyspnea 51 days after the first visit. PH, despite partial PVS, may also be associated with concurrent parenchymal lung disease. Sildenafil can worsen pulmonary edema in the affected lung but did not in this case.

Authors: Herdiati Meilisa Fani , Fitriyah Hadiah
Published: May 2024

This study examines how waiting time and health literacy-sensitive communication (HL-COM) affect patient satisfaction in the executive outpatient unit of Hospital Z. Using a sample of 120 respondents and analyzing data with Partial Least Square (PLS) structural equation modeling, we found that waiting time negatively impacts patient satisfaction. However, HL-COM significantly moderates this effect, mitigating the negative impact of waiting time. These findings suggest that hospital management should focus on both reducing waiting time and improving doctor-patient communication to enhance patient satisfaction.
Highlights:

Negative Impact: Waiting time significantly reduces patient satisfaction.
Moderating Role: HL-COM moderates the effect of waiting time on satisfaction.
Management Focus: Reduce waiting time and enhance doctor-patient communication.

Keywords: Patient satisfaction, waiting time, health literacy-sensitive communication, hospital management, Partial Least Square (PLS)

Authors:   Department of Yoga Research, Patanjali Research Foundation, Haridwar 249405, Uttarakhand, India, Vishwakarma, Babita
Published: May 2024

Background: Previously, the reasons to practice yoga were reported in non-clinical populations. Patients’ motivators for yoga as therapy have not been reported. Methods: A convenience sampling survey was conducted on 1077 patients (age range: 18-83 years; M:F=57.17:42.83) at a yoga therapy in India. Participant reported motivators for yoga therapy were assessed with a multiple choice questionnaire. Results: The three most common motivators for yoga therapy were: (i) advice from close associates (26.3 percent), (ii) disease symptom reduction (20.0 percent) and (iii) interest in yoga (14.9 percent). The motivators to yoga differed for patients with and without prior exposure to yoga (Chi square =79.42, df = 16, p<0.001, Cramer’s V = 0.29). Conclusions: In the present clinical population, the motivators for yoga as a therapy differ based on prior exposure to yoga.
Evaluation of “Cognitive Behavioral Intervention for Trauma in Schools” (CBITS) in child welfare programs in Germany: Study Protocol of a Randomized Controlled Trial
Authors: Pfeiffer Elisa , Dörrie Loni , Köksal Jessica , Krech Fabienne , Muche Rainer , Segler Jacob , Sachser Cedric
Published: May 2024

Background
Children and adolescents growing up in child welfare institutions have been frequently exposed to traumatic events, psychosocial stress and show elevated rates of mental disorders. Yet there is a lack of empirically supported treatments to provide adequate mental health care for children in care suffering from trauma-related mental disorders such as posttraumatic stress disorder (PTSD), depression and anxiety. The Cognitive Behavioral Intervention for Trauma in Schools (CBITS) is an evaluated trauma-focused cognitive-behavioral group intervention, which has proven to be effective in reducing symptoms of PTSD, depression and anxiety for traumatized children in group settings. The trial will evaluate effectiveness of the CBITS intervention as an outreach treatment compared with an enhanced treatment as usual condition (TAU+) within the German mental health and child welfare system.
Methods
In a randomized controlled trial (RCT) involving N = 90 children and adolescents, we will compare CBITS with TAU+. Participants between 8–16 years, reporting at least one traumatic event and moderate Posttraumatic Stress Symptoms (PTSS) will be randomized within their child welfare institution to either one of the conditions using a CATS-2 severity stratified block randomization. Assessments will take place at baseline, as well as 4 months and 10 months after baseline. The primary outcome is the severity of PTSS after 4 months. Secondary outcomes are depression, anxiety, irritability/anger, quality of life and global functioning level.
Discussion
The results of our trial will provide evidence regarding effective treatment options for traumatized children in care, which represent an understudied population with limited access to mental health care. Additionally, it could serve as blueprint for implementing trauma-focused outreach group treatments for children in care and increase the accessibility to appropriate treatment.

Neuromorphic computing has attracted great attention for its massive parallelism and high energy efficiency. As the fundamental components of neuromorphic computing systems, artificial neurons play a key role in information processing. However, the development of artificial neurons that can simultaneously incorporate low hardware overhead, high reliability, high speed, and low energy consumption remains a challenge. To address this challenge, we propose and demonstrate a piezoelectric neuron with a simple circuit structure, consisting of a piezoelectric cantilever, a parallel capacitor, and a series resistor. It operates through the synergy between the converse piezoelectric effect and the capacitive charging/discharging. Thanks to this efficient and robust mechanism, the piezoelectric neuron not only implements critical leaky integrate-and-fire functions (including leaky integration, threshold-driven spiking, all-or-nothing response, refractory period, strength-modulated firing frequency, and spatiotemporal integration), but also demonstrates small cycle-to-cycle and device-to-device variations (~1.9% and ~10.0%, respectively), high endurance (107), high speed (integration/firing: ~9.6/~0.4 μs), and low energy consumption (~13.4 nJ/spike). Furthermore, spiking neural networks based on piezoelectric neurons are constructed, showing capabilities to implement both supervised and unsupervised learning. This study therefore demonstrates the piezoelectric neuron as a simple yet reliable, fast, and energy-efficient artificial neuron, and also showcases its applicability in neuromorphic computing.

In today's ever-evolving networking landscape, Software Defined Networking (SDN) has emerged as a paradigm-shifting technology that promises greater flexibility, agility, and control over network infrastructures. However, how easy are the configuration, extensibility, and programmability of these SDN controllers, considering the practical implications for network administrators and developers? This study aims to explore the practical implementation and comparative evaluation of different SDN Controllers within diverse simulated network environments. Prominent controllers such as POX and Faucet are meticulously configured and deployed in simulated network environments created using GNS3, NS3, OPNET, OMNET + + and MININET platforms. Furthermore. the study employs a range of performance metrics like controller latency, network throughput, packet loss, CPU and memory utilization to assess the efficacy and efficiency of each SDN Controller.

The effect of feeding bush-based finishing rations on the performance of Damara lambs was studied. Thirty weaned lambs weighing 16.7 ± 1.9 kg were allocated to five treatments in a completely randomized design over a 90-day feeding period. The control diet (T1), consisted of Lucerne (10%), grass hay (30%) and concentrate mix (60%). Treatments T2-T5 consisted of roughage (40%) from the milled bushes Senegalia mellifera, Dichrostachys cinerea, Terminalia sericea and Rhigozum trichotomum respectively, and concentrate mix (60%). At the end of the feeding trial, the lambs were slaughtered and carcass characteristics were evaluated. The average daily feed intake (ADFI) was affected (P < 0.05) by sex, treatment, week and treatment x week interactions. The ADFI for T1 exceeded (P < 0.05) that for T2 and T3, at most time points. The ADFI of T1 and T4 were similar (P > 0.05) at weeks 6 to 10, but differed (P < 0.05) at other time points. The average daily gain (ADG) and feed conversion ratio (FCR) were affected (P < 0.05) by sex and treatment. The ADG (g/day) least squares means (± S.E) for T1 – T5 were 148.0 ± 6.9, 156.4 ± 6.9, 124.2 ± 6.9, 133.7 ± 6.9 and 133.7 ± 6.9, respectively. Treatment T2 had a better (P < 0.05) FCR compared to other bush-based treatments. Males had heavier (P < 0.05) final, hot and cold carcass weights than females. Lambs fed T4 had greater (P < 0.05) rib eye area than T1 (8.3 ± 0.5 vs. 5.9 ± 0.5 mm2). Bush-based diets can serve as production diets for weaned sheep and result into acceptable weight gain and carcass quality.

Published: May 2024

Internet addiction is an emerging mental health concern, particularly among young people who avidly use online technologies. This cross-sectional study examined the predictive relationship between curiosity and internet addictive behaviours among 480 tertiary students in Ghana. Data were collected using Kashdan's Curiosity Scale and Samaha’s Internet Addiction Test. The results revealed a 13.1% prevalence rate of internet addiction, with 73.1% classified as over-users. Only 29.4% exhibited high curiosity levels, while 35.6% had low curiosity. Structural equation modelling showed that deprivation sensitivity, covert social curiosity, overt social curiosity, stress tolerance, and thrill-seeking positively predicted various dimensions of internet addiction. Conversely, joyous exploration negatively predicted these behaviours. The curiosity composite positively predicted the overall internet addiction composite. The findings highlight curiosity’s complex role, where adaptive curiosity mitigates internet addiction risks, but maladaptive curiosity exacerbates such risks. Nurturing healthy curiosity while equipping students with self-regulation skills is crucial for promoting responsible internet use and preventing addictive behaviours. This study contributes insights into curiosity’s influence on youth mental health, informing prevention and intervention strategies within Ghana's tertiary education context.

Drug resistance in cancer poses a serious challenge in finding an effective remedy for cancer patients, because of the multitude of contributing factors influencing this complex phenomenon. One way to counter this problem is using a more targeted and dose-limiting approach for drug delivery, rather than relying on conventional therapies that exhibit multiple pernicious side-effects. Stability and specificity have traditionally been the core issues of peptide-based delivery vectors. In this study, we employed a structural regression modelling approach in the design, synthesis and characterization of a series of peptides that belong to approximately same topological cluster, yet with different electrostatic signatures encoded as a result of their differential positioning of amino acids in a given sequence. The peptides tagged with the fluorophore 5(6)-carboxyfluorescein,showed higher uptake in cancer cells with some of them colocalizing in the lysosomes. The peptides tagged with the anti-cancer drug methotrexate have displayed enhanced cytotoxicity and inducing apoptosis in triple-negative breast cancer cells. They also showed comparable uptake in side-population cells of lung cancer with stem-cell like properties. The most-optimized peptide showed accumulation in the tumor resulting in significant reduction of tumor size, compared to the untreated mice in in-vivostudies. Our results point to the following directives; (i) peptides can be design engineered for targeted delivery (ii) stereochemical engineering of peptide main chain can resist proteolytic enzymes and (iii) cellular penetration of peptides into cancer cells can be modulated by varying their electrostatic signatures.

Published: May 2024

Purpose: The aim of our study was to investigate sociodemographic factors, comorbidities and health behaviors associated with self-reported diagnosed cataract in a large, nationally representative population of older adults in Poland, aged 60 and above.
Patient and Methods: An analysis was conducted on a survey among 5956 participants of the nationally representative PolSenior2 study conducted between 2018 and 2019. Multiple logistic regression analysis was employed to ascertain the association between self-reported diagnosed cataract and sociodemographic factors, health behaviors, and comorbidities.
Results: In the final multivariate model, the odds radio (OR) of self-reported diagnosed cataract were 1.71 times higher among women compared to men. Additionally, the odds increased significantly with age, with 70-79-year-olds having 3.38 times higher odds, 80-89-year-olds having 8.08 times higher odds, and those aged 90 years and older having 10.76 times higher odds compared to the reference group (60-69 years old). The prevalence of self-reported diagnosed cataract was found to be 1.47 times higher among individuals with diabetes, 1.20 times higher among those with hypertension, and 1.25 times higher among tobacco users compared to their respective counterparts. Additionally, rural dwellers exhibited a lower risk for self-reported cataract (OR = 0.63).
Conclusion: Our study revealed a positive correlation between several demographic and health factors—namely, older age, female gender, urban residence, hypertension, diabetes, and smoking—and an elevated risk of cataract.
