Published: July 2023

OBJECTIVES: Active surveillance for low-risk prostate cancer closely monitors patients conservatively instead of the pursuit of active treatment to reduce overtreatment of insignificant disease. Since 2009, active surveillance has been recommended as the primary management option in the European Association of Urology guidelines for low-risk disease. The present study aimed to investigate the use and uptake of active surveillance over 10 years in our certified prostate cancer centre (University Hospital of Zurich) compared with those derived from the cancer registry of the canton of Zurich, Switzerland.

MATERIALS AND METHODS: We retrospectively identified all men diagnosed with low-risk prostate cancer at our institution and from the cancer registry of the canton of Zurich from 2009 to 2018. The primary treatment of each patient was recorded. Descriptive statistics were used to analyze the use of different treatments in our centre. The results were compared with those derived from the cancer registry.

RESULTS: A total of 3393 men with low-risk prostate cancer were included in this study (University Hospital of Zurich: n = 262; cancer registry: n = 3131). In the University Hospital of Zurich and cancer registry cohorts, 146 (55.7%) and 502 (16%) men underwent active surveillance, respectively. The proportions of local treatment [115 (43.9%) vs 2220 (71%)] and androgen deprivation therapy [0 (0%) vs 43 (1.4%)] were distinctly lower in the University Hospital of Zurich cohort than in the cancer registry cohort. The uptake of active surveillance over the years was high in the University Hospital of Zurich cohort (35.4% in 2009 and 88.2% in 2018) but only marginal in the cancer registry cohort (12.2% in 2009 and 16.2% in 2018).

CONCLUSION:Despite clear guideline recommendations, active surveillance for low-risk prostate cancer is still widely underused. Our analysis showed that access to a certified interdisciplinary tumour board significantly increases the use of active surveillance.

A Framework based on a Pattern Language for Business Resource Management
Authors: Braga Rosana T. Vaccare , Masieiro Paulo Cesar
Published: July 2023

A framework based on a pattern language for Business Resource Management is under construction to be used for developing systems in the information systems domain. Business resources include assets and services, as products and repairs. By management we mean their trade, rental and maintenance. A pattern language has been developed for aiding in the analysis of systems for business resource management. It includes fourteen patterns for identifying the resource, quantifying it, renting, trading and maintaining it, reserve it, quote the trade, quote the maintenance, check its delivery, allowing several items to be dealt with in the same transaction, paying for the transaction, identifying the transaction executor, and identifying maintenance tasks and parts. One of the patterns is included, corresponding to trading the resource. A class model shows its structure (classes and relationships), and an application example shows the roles played by each participant class. An example of the pattern language usage for a car repair shop system is presented, together with an object model that shows the patterns used and the roles played by their participant classes. The present development stage of the framework is mentioned.
Die Abgeordneten im Landtag Mecklenburg-Vorpommerns: Sozialprofil im Wandel
Authors: Diesing Johannes
Published: July 2023

Over the course of the process of transformation in East Germany elites from the West moved into the new Bundesländer of the East . This transfer took place in a number of domains of society including the political system of the new Bundesländer . After 30 years it can be assumed that the social profile of Members of Parliament in the Bundesländer did change once again, due to a generation of politicians which grew up during the collapse of 1989 and the following years of transformation [German: Wendekinder] . This article examines the social profile of Members of Parliament in the current Landtag of Mecklenburg-Vorpommern as well as its development over the last 30 years . The article focuses on the legislative periods of the first (1990-1994), the sixth (2011-2016) and the eighth (2021-ongoing) Landtag of Mecklenburg-Vorpommern . Biographical data was gathered on date and place of birth and moving into the Bundesland as well as secondary school qualifications and vocation before entering the Parliament from publicly available parliamentary documents and analyzed the distribution of these items to compare differences and continuities .

Aportación al modelado del motor trifásico de inducción con consideración de la saturación y el efecto de doble jaula
Authors:   , Martín Cañadas María Elena
Published: July 2023

El gran atractivo del modelo estándar del motor de inducción en ejes dq con parámetros constantes reside en su relativa simplicidad, por lo que generalmente se toma como base para la predicción de su conducta dinámica.
No obstante, durante transitorios exigentes y en determinadas condiciones de operación, este modelo se revela claramente inadecuado para representar el comportamiento de la máquina.
Para paliar este hecho, numerosos esfuerzos se han efectuado para incluir en el modelo del motor efectos tales como el de ranura profunda o la saturación magnética, así como otros fenómenos de segundo orden. No obstante, el enorme incremento en complejidad experimetado por el modelo desincentiva su utilización.
En la presente tesis se explora la bondad de determinados modelos simplificados con inclusión del efecto de ranura profunda y la saturación magnética del flujo principal, evaluando bajo qué condiciones su utilización ofrece garantías.
Concretamente, se muestra la necesidad del empleo de modelos con inclusión del efecto de ranura profunda para la determinación del tiempo de operación estable del motor trifásico de inducción ante huecos de tensión, evidenciando cómo aun los modelos de orden reducido, mas de doble jaula, predicen resultados acordes con los datos de catálogo suministrados por el fabricante, cometido en el que falla el modelo estándar de jaula sencilla.
En lo tocante al modelado de la saturación magnética, se justifica la divergencia en los resultados obtenidos a partir de los modelos con y sin intersaturación cuando estos son formulados en función de determinados conjuntos de variables de estado, a partir de la evaluación de los pesos relativos de los distintos términos que marcan la diferencia entre ambos tipos de modelos, contribuyendo así a clarificar un punto que ha sido objeto de controversia en la literatura especializada. Se efectúa, así mismo, un estudio detallado sobre las implicaciones del uso de parámetros y magnitudes referidos en los modelos con y sin intersaturación, evaluando para qué conjuntos de variables de estado su utilización resulta ventajosa.
En suma, queda puesto de manifiesto que haciendo uso de determinados recursos simplificativos, es posible modelar con garantías efectos que en muchas ocasiones son obviados en los modelos para evitar la excesiva complejidad que su inclusión aporta, pero que en aplicaciones concretas resultan esenciales para representar adecuadamente el comportamiento real del motor.

Arquitectura i màquina : principis d'instal·lacions als edificis
Authors: Serra Florensa Rafael , Isalgué Buxeda Antonio , Sánchez Lluïsa
Published: July 2023

Les instal·lacions, ja siguin de sistemes de serveis o bé de control ambiental, s'han entès sempre com elements incòmodes afegits a l'arquitectura que cal amagar o dissimular en els edificis. Entenem que després de més de dos segles de civilització industrial ja és hora que l'arquitectura comenci a utilitzar obertament aquests nous recursos i n'aprofiti totes les seves possibilitats tècniques i estètiques. Aquest llibre planteja els principis bàsics d'aquests sistemes des d'un punt de vista arquitectònic. Així s'estableixen els conceptes científics de tot allò que després es podrà resoldre en el disseny amb sistemes tècnics concrets que no es tracten en aquesta obra. Considerem que el coneixement dels principis de funcionament de les coses és més important i útil que el de les solucions específiques, sotmeses avui a un procés d'obsolescència molt ràpid.

Authors:   Pakistan Institute of Development Economics (PIDE), Islamabad, SHAHZAD SHAKEEL
Published: July 2023

This study was conducted to examine the role of financial inclusion in economic growth, poverty, and income inequality in developing countries from 2010 to 2020. A panel data consisting of 101 countries for the period 2010 to 2020 was compiled from the World Development Indicators and the Global Financial Inclusion Database (Global Findex Database). The collected data was analyzed using the System Generalized Method of Moments. The study's findings indicate that financial inclusion has a positive impact on improving economic growth and reducing income inequality in developing countries. However, contrary to existing literature, this study found that financial inclusion has a direct relationship with poverty, which can be attributed to the economic peculiarities of developing countries. Therefore, this study concludes that financial inclusion contributes to improved economic growth and reduced income inequality. Although it may not directly alleviate absolute poverty, it helps reduce poverty through the mechanisms of income inequality and economic growth. It is recommended that policymakers and regulators in respective countries focus on expanding the scope of financial inclusion to enhance economic growth and reduce income inequality.
Game Changer for Pakistan: Significance of Gawadar for Pakistan Economy & Factors of Underutilization of Gawadar Port
Authors:   Lahore Leads University, Anwar Usman , Hussain Dr. Zakir ,   Assistant Professor, Lahore Leads University
Published: July 2023

Gwadar is a game-changer for Pakistan's economy because of its tremendous potential for growth and development across many industries. The Pakistani government initiated the Gwadar Port Project in the early 2000s with the goal of making the deep-sea port a significant entrance point for trade and business, linking Pakistan with the Middle East, Central Asia, and other regions. The project was built and run mostly by China, with financial support from Pakistan. China-Pakistan Economic Corridor (CPEC) initiative will play a significant role in the development of Gwadar, which is now viewed as a strategic asset for Pakistan and China's economic interests. CPEC aims to connect China's western region with the Gwadar port through a network of highways, railways, and pipelines. Gwadar is an essential part of China's Belt and Road Initiative (BRI), a vast infrastructure and development project that aims to improve regional connectivity and promote economic growth throughout Asia and beyond. Gwadar is a key strategic asset for Pakistan's economy with the potential to fundamentally alter the country's trade and commerce environment. It is located at the junction of crucial trade and energy routes and has the potential to become a gateway to the rest of the globe, connecting Pakistan to Central Asia, the Middle East, and beyond. Thanks to its deep-water facilities and advantageous location, the port makes a perfect transit point for both international trade and energy supplies via pipelines and other infrastructure. The Gwadar Free Zone, a special economic zone within the port, aims to attract investment and provide a business-friendly environment for businesses. This will enhance possibilities. Pakistan has a coastline of approximately 1,050 kilometers along the Arabian Sea, making it a country with significant potential to harness the benefits of the ocean for its economy. Pakistan can harness the benefits of the ocean for its economy by investing in its fishing industry, shipping industry, offshore oil and gas exploration, tourism industry, and renewable energy sector. The government must ensure sustainable and responsible use of ocean resources while promoting economic growth.

Published: July 2023

Owing to the widespread use of pesticides all over the world and the lack of effective remediation technologies, the persistence of pesticides in the soil has emerged as a serious environmental issue. Although pesticides have a great impact on increasing yield and benefitting cultivators economically, the indiscriminate application of pesticides in croplands has become a threat to the well-being of the natural ecosystems. Pesticides represent one of the most toxic soil pollutants and represent a significant risk to human wellness as well as the natural ecology. The bioremediation process, which utilizes bacteria, fungi, algae, and other organisms, has proved to be one of the most cost-effective and environmentally beneficial solutions to this growing problem. A number of approaches employing bioremediation technologies have successfully been implemented in the field. However, more adaptable, cost effective and easily implementable approaches need to be developed that can deliver the intended outcome. This review elucidates the present status of pesticide contamination and highlights the predominant role played by microbes in pesticide remediation, along with the advances made in recent years.
A Field Guide to Forest Seeds

Seeds are incredible because they are smaller versions of the entire plant, concealing the entire tree structure under the skin and allowing them to thrive in favorable conditions. Seeds have been known to humans from the beginning of time, and they have played an important role from nomadic farming to precision farming. These are employed in a variety of ways, including food, decorative, cosmetics, medicine, pharmaceuticals, and so on, harnessing their physiochemical or biological qualities. Seed descriptions, including phenology, distribution, and basic seed handling techniques for more than 75 tree and plant species utilized in forestry programs, have been compiled and presented with seed photos in this book. This book will greatly benefit students, field personnel, and others interested in forest nursery activities.

Authors:   University of Eastern Africa, Baraton, Mohammed Isiko , Gude Korso , Balyage Yona
Published: July 2023

The current study ascertained signs that differentiated supervision is implemented to improve teacher performance in public primary schools in Iganga District. A descriptive cross-sectional design was used on a sample of 481 respondents selected using stratified, purposive, and simple random sampling techniques. A questionnaire and interview guide were used to collect data. Mean and standard deviations were used to rate the items while the relationship between differentiated supervision appraisal and teacher performance was tested using correlation and regression analyses. A regression analysis was performed to respond to each of the hypotheses using a p-value of 0.05. According to findings, differentiated supervision positively predicts teacher performance (B = 0.040; p =.405>0.05). Based on these results, therefore, there is no statistically significant evidence of differentiated supervision is implemented to improve teacher performance in public primary schools. Conclusively, performance appraisal is used in public primary schools in Iganga District but have a marginal impact on teacher performance. The district reports, which indicate that performance appraisal informs excellence in teacher performance, were not the case in public primary schools given the weak coefficients. It was recommended that teachers need to develop a love for the profession, the head teacher's presence in schools should be increased, and the ministry of education should invest more money in school inspections.

Content of English Language Certificate Examination in Primary School in Cameroon: An Analysis.
Authors:   University of Buea, Cameroon, Tante Achu
Published: July 2023

In many countries in sub-Saharan Africa an official language is used as either a second or foreign language. In the case of Cameroon English is used as a second language by the English-medium population from pre-nursery to university. Instruction apart English language is employed for formal, informal and government situations. What is more it is the language for career prospects. This is not easy especially for young children who are still in the process of developing in their L1. English language competence therefore most often is related to academic success and progress. This article analyses the examination content of the First School Leaving Certificate (FSLC) in Cameroon. The general argument is that the English language competence and performance of successful primary school graduates still falls short of expectation. A number of reasons have been given for this low level such as use of the Communicative Language Approach, the young ages of pupils and inadequate resources. By analysing the content of the examination from 2014-2015 indicators may be drawn with regard to the appropriateness to expected skills and abilities. Discussions are made further in the light of similar contexts and suggestions are drawn to inform ESL/EFL summative assessment practice of Young Learners world-wide.
Architecture and the subconscious
Authors: Paramita Kristanti Dewi
Published: July 2023

The subconscious thinking governs the way the built environment is experienced and organised by its inhabitants. The collection of articles in this issue of ARSNET explores how our subconscious thinking provides alternative spatial narrative and design methods. The explorations in this issue highlight the different conditions and realms of the subconscious, as well as the various ways of learning and making driven by subjective subconsciousness. These inquiries offer deep thought on how the focus on subconscious thinking reveals hidden experiences and knowledge of architecture, as well as celebrating speculations and open-ended qualities that allow architecture to evolve.
The Dirichlet divisor problem over square-free integers and unitary convolutions

Published: July 2023

We obtain an asymptotic formula for the sum $\tilde{D}_2$ of the divisors of all square-free integers less than or equal to $x$, with error term $O(x^{1/2 + \epsilon})$. This improves the error term $O(x^{3/4 + \epsilon})$ presented in [7] obtained via analytical methods. Our approach is elementary and it is based on the connections between the function $\tilde{D}_2$ and unitary convolutions.

The vertebrate brain is highly conserved topologically, but less is known about neuroanatomical variation between individual brain regions. Neuroanatomical variation at the regional level is hypothesized to provide functional expansion, building upon ancestral anatomy needed for basic functions. Classically, animal models used to study evolution have lacked tools for detailed anatomical analysis that are widely used in zebrafish and mice, presenting a barrier to studying brain evolution at fine scales. In this study, we sought to investigate the evolution of brain anatomy using a single species of fish consisting of divergent surface and cave morphs, that permits functional genetic testing of regional volume and shape across the entire brain. We generated a high-resolution brain atlas for the blind Mexican cavefish Astyanax mexicanus and coupled the atlas with automated computational tools to directly assess variability in brain region shape and volume across all populations. We measured the volume and shape of every grossly defined neuroanatomical region of the brain and assessed correlations between anatomical regions in surface fish, cavefish, and surface × cave F2 hybrids, whose phenotypes span the range of surface to cave. We find that dorsal regions of the brain are contracted, while ventral regions have expanded, with F2 hybrid data providing support for developmental constraint along the dorsal-ventral axis. Furthermore, these dorsal-ventral relationships in anatomical variation show similar patterns for both volume and shape, suggesting that the anatomical evolution captured by these two parameters could be driven by similar developmental mechanisms. Together, these data demonstrate that A. mexicanus is a powerful system for functionally determining basic principles of brain evolution and will permit testing how genes influence early patterning events to drive brain-wide anatomical evolution.

The defensive–offensive associations between algae and herbivores determine marine ecology. Brown algae utilize phlorotannin as their chemical defense against the predator Aplysia kurodai, which uses β-glucosidase (akuBGL) to digest the laminarin in algae into glucose. Moreover, A. kurodai employs Eisenia hydrolysis-enhancing protein (EHEP) as an offense to protect akuBGL activity from phlorotannin inhibition by precipitating phlorotannin. To underpin the molecular mechanism of this digestive–defensive–offensive system, we determined the structures of the apo and tannic acid (TNA, a phlorotannin analog) bound forms of EHEP, as well as the apo akuBGL. EHEP consisted of three peritrophin-A domains arranged in a triangular shape and bound TNA in the center without significant conformational changes. Structural comparison between EHEP and EHEP–TNA led us to find that EHEP can be resolubilized from phlorotannin precipitation at an alkaline pH, which reflects a requirement in the digestive tract. akuBGL contained two GH1 domains, only one of which conserved the active site. Combining docking analysis, we propose the mechanisms by which phlorotannin inhibits akuBGL by occupying the substrate-binding pocket, and EHEP protects akuBGL against this inhibition by binding with phlorotannin to free the akuBGL pocket.

Rapid conversion of force into a biological signal enables living cells to respond to mechanical forces in their environment. The force is believed to initially affect the plasma membrane and then alter the behavior of membrane proteins. Phospholipase D2 (PLD2) is a mechanosensitive enzyme that is regulated by a structured membrane-lipid site comprised of cholesterol and saturated ganglioside (GM1). Here we show stretch activation of TWIK-related K+ channel (TREK-1) is mechanically evoked by PLD2 and spatial patterning involving ordered GM1 and 4,5-bisphosphate (PIP2) clusters in mammalian cells. First, mechanical force deforms the ordered lipids, which disrupts the interaction of PLD2 with the GM1 lipids and allows a complex of TREK-1 and PLD2 to associate with PIP2 clusters. The association with PIP2 activates the enzyme, which produces the second messenger phosphatidic acid (PA) that gates the channel. Co-expression of catalytically inactive PLD2 inhibits TREK-1 stretch currents in a biological membrane. Cellular uptake of cholesterol inhibits TREK-1 currents in culture and depletion of cholesterol from astrocytes releases TREK-1 from GM1 lipids in mouse brain. Depletion of the PLD2 ortholog in flies results in hypersensitivity to mechanical force. We conclude PLD2 mechanosensitivity combines with TREK-1 ion permeability to elicit a mechanically evoked response.

The study was conducted to investigate the effective management of some major insect pests of soybean in the research field of Sher-e-Bangla Agricultural University, Dhaka during the period from December, 2020 to March 2021. The experiment was designed with Randomized Complete Block Design (RCBD) with three replications. During this experiment total six insecticides were tested viz., Lambda-Cyhalothrin @1ml/L of water Neemoil @1ml/L of water with 3g of detergent; Thiamethoxam @0.5g/L of water; Spinosad @0.5ml/L of water; Chlorantraniliprole @0.3ml/L of water; Emamectin Benzoate @1ml/L of water. Data on different pests populaton number and yield were collected and recorded. The lowest population per unit of whitefly and jassid was found in Emamectin Benzoate @1ml/L of water treated plots after consecutive three times application. Similarly, lowest unit of aphid was found in Chlorantraniliprole @0.3ml/L of water; treated plots. On the other hand, Thiamethoxam @0.5gl/L of water were found effective against whitefly, aphid, pod borer per plant, while the highest infestation was observed in control plots. The maximum yield was 1.68 t/ha, observed from Emamectin Benzoate @1ml/L of water, followed by (1.61 t/ha ) Chlorantraniliprole @0.3ml/L of water Among the treatments, Emamectin Benzoate @1ml/L of water was more effective for the controlling of insect pests as well as yield of soybean.

Facing the future development trend of miniaturization and intelligence of electronic devices, solar‐blind photodetectors based on ultrawide‐bandgap 2D semiconductors have the advantages of low dark current, and high signal‐to‐noise ratio, as well as the features of micro‐nanometer miniaturization and multi‐functionalization of 2D material devices, which have potential applications in the photoelectric sensor part of high‐performance machine vision systems. This study reports a 2D oxide semiconductor, AsSbO3, with an ultrawide bandgap (4.997 eV for monolayer and 4.4 eV for multilayer) to be used to fabricate highly selective solar‐blind UV photodetectors, of which the dark current as low as 100 fA and rejection ratio of UV‐C and UV‐A reaches 7.6 × 103. Under 239 nm incident light, the responsivity is 105 mA W−1 and the detectivity is 7.58 × 1012 Jones. Owing to the remarkable anisotropic crystal structure, AsSbO3 also shows significant linear dichroism and nonlinear optical properties. Finally, a simple machine vision system is simulated by combining the real‐time imaging function in solar‐blind UV with a convolutional neural network. This study enriches the material system of ultrawide‐bandgap 2D semiconductors and provides insight into the future development of high‐performance solar‐blind UV optoelectronic devices.

Living materials represent a new frontier in functional material design, integrating synthetic biology tools to endow materials with programmable, dynamic, and life‐like characteristics. However, a major challenge in creating living materials is balancing the tradeoff between structural stability, mechanical performance, and functional programmability. To address this challenge, a sheath–core living hydrogel fiber platform that synergistically integrates living bacteria with hydrogel fibers to achieve both functional diversity and structural and mechanical robustness is proposed. In the design, microfluidic spinning is used to produce hydrogel fiber, which offers advantages in both structural and functional designability due to their hierarchical porous architectures that can be tailored and their mechanical performance that can be enhanced through a variety of post‐processing approaches. By introducing living bacteria, the platform is endowed with programmable functionality and life‐like capabilities. This work reconstructs the genetic circuits of living bacteria to express chromoproteins and fluorescent proteins as two prototypes that enable the coloration of living fibers and sensing water pollutants by monitoring the amount of fluorescent protein expressed. Altogether, this study establishes a structure–property–function optimized living hydrogel fiber platform, providing a new tool for accelerating the practical applications of the emerging living material systems.

Halide perovskite colloidal nanocrystals (NCs) have enabled considerable progress in light conversion applications. However, the presence of unavoidable defect states and phase transition effects can accelerate undesirable rapid charge recombination of the photogenerated charge carriers. To address this issue, chromophores with an anchoring moiety are often used to modify the surface of the NCs, promoting prolonged charge separation through electron or energy transfer processes for optoelectronic applications. Here, steady‐state and time‐resolved spectroscopy methods are combined with density functional theory (DFT) calculations to explore and decipher the excited‐state interaction in colloidal CsPbX3 (X = Br, I) NCs with a rhodamine 6G (Rh6G) hybrid assembly. The results show that Rh6G dimerizes even at low concentrations, as evidenced by DFT calculations. The binding of Rh6G on the NC surface is confirmed by FTIR and NMR spectroscopy techniques. In addition, transient absorption spectroscopy reveals directional sub‐ps electron transfer from Rh6G to CsPbI3 NCs, whereas energy transfer occurs from CsPbBr3 to Rh6G, which ultimately recombines in the µs time regime. The findings highlight the simplest and most practical approaches for studying and tailoring the excited‐state interaction in colloidal perovskite NCs and chromophore assembly.
