How good is lobectomy for the Turkish population with papillary thyroid cancer? A clinicopathological evaluation
Authors: Konca Can
Published: February 2024

Objective: In modern practice, there is an increasing recommendation for higher utilization of lobectomy in the management of papillary thyroid cancer (PTC). However, in this decision where the optimal balance of locoregional recurrence and complication burden should be achieved, there are still conflicting results in the literature. The aim of this study was to evaluate the effect of high-risk factors in the Turkish population with PTC on the decision of hypothetical lobectomy.

Material and Methods: In this study, 96 PTC patients undergoing total thyroidectomy were retrospectively analyzed. Preoperative and postoperative evaluation differences and the impact of high-risk factors (tumor size, multifocality, extrathyroidal extension and central lymph node metastasis) on the decision for hypothetical lobectomy were investigated.

Results: In all patients and lobectomy-eligible patients, postoperative evaluations of multifocality, contralateral multifocality, and central lymph node metastases were significantly higher than preoperative evaluations. Consequently, postoperative evaluation revealed that completion thyroidectomy would be required in 52.9% of 51 patients who were hypothetically suitable for lobectomy. Furthermore, comparisons of tumor size-based grouping in lobectomy and total thyroidectomy suitable patients showed similar high-risk factor distribution except for central lymph node metastasis for tumors <10 mm and contralateral multifocality between 11-20 mm.

Conclusion: Completion thyroidectomy will be required in approximately half of the patients evaluated as suitable for lobectomy in the treatment of PTC in the Turkish population. In the treatment decision, in which many patient- and surgeon-related factors are influential, each patient should be considered separately.

Contemporaneity of Modernism as an Aesthetic Innovation
Authors: Jose Antony , Grace VM Berlin , Wilson D David
Published: February 2024

Modernism as a literary movement can be periodized from the point of literary history where postmodernism follows modernism. However, modernism as an aesthetic innovation was ever-present in so-called postmodernism and is present in the contemporary literary world. In other words, because of modernism’s open-ended nature as an aesthetic innovation as well as the essential presence of newness in the term, the contemporary is forced to rely on modernism as the frame that can help it define its own identity. Contemporary authors reveal their relationship with modernism and contemporary literature demonstrates the recurring presence of modernism even beyond historical periodization. As a stylistic mode, modernism becomes more dominant in the contemporary. In today's neoliberal capitalism, key components of modernist thinking and art reappear in contemporary situations to serve a specific purpose. Thus, modernism is not a closed movement of the past but is a recurring presence in the contemporary literary world as an aesthetic intervention. This paper through the conceptual analysis of the term as well as its usage, investigates the contemporaneity of modernism to comprehend how modernism is not only back or can be said to have resurfaced, but also how modernism is ever present as an aesthetic innovation in contemporary literature.

Published: February 2024

Since the 21st century, Lamreh, Aceh Besar Regency, Indonesia played an important role during the maritime silk route at the gate of the Malacca strait. This article investigates the subsurface structure of landslide-prone areas in cultural heritage based on 2D resistivity, chargeability and current density models of ERT, IP and VLF-EM methods, respectively. Field data measurements were carried out on 2 crossing profiles along the cliff suspected of experiencing landslides. The length of each profile is 220 with 4 m distance between stations. The 2D models reveal that the subsurface geological structure of Lamreh is composed of a mixed layer of clastic sediment and volcanic material at the top, followed by a layer of calcareous sandstone, and volcanic breccia at the bottom. The 3 layers are most easily distinguished in the resistivity model. The topmost layer is permeable but dry, i.e., characterized by a more resistive layer in the models. While the second layer is characterized by an intermediate conductivity and the bottom layer is highly conductive. The conductivity in these 2 layers is influenced by the degree of water content within the rocks. The chargeability models derived from IP data can distinguish between the dry layer on the surface and the saturated layer below. Meanwhile, the current density models obtained from VLF-EM data have proven the presence of fractures and faults along the profiles due to weathering as also seen in the resistivity models.

Metabolomic and Growth Responses of Houttyunia cordata to Varying Light Intensities and Subsequent Effects on Fermented Products
Authors: Boonchaisri Siriwat , Mokoed Chutima , Phuangchaona Phanumat , Treenate Ekawit
Published: February 2024

Suitable light intensities were studied to enable sustainable and efficient cultivation of Houttuynia cordata with a high yield of bioactive compounds which later can be a good quality material for fermentation. To achieve this goal, the evaluation of physiological adaptation and elucidation of the metabolic alterations of Houttuynia cordata in response to different light intensities were conducted. Four-month-old H. cordata was exposed to 3 different light intensities: high light, control, and low light (100, 50 and 20 % natural irradiances, respectively). Physiological responses were measured using leaf gas exchange. The same leaf samples were either methanolic extracted for LC-QTOF-MS analysis to generate metabolite fingerprints or fermented for 3 months prior to quercetin quantification. High light treatment had the greatest effects on both the physiology and metabolisms of H. cordata compared to control and low light treatments. Compared to the control, the key results observed in high-light-grown H. cordata were a significant increase in photosynthesis, a decrease in relative chlorophyll contents, the enrichment of the top 3 metabolic pathways (phenylpropanoid biosynthesis, pyruvate metabolism and fatty acid degradation) and increasing quercetin concentrations in both fresh and fermented leaves. Metabolite fingerprints of high light-grown H. cordata were distinctively different from those of the other 2 treatments according to PCA and hierarchical clustering analysis. In conclusion, H. cordata responded to high light intensity by enriching the phenylpropanoid biosynthetic pathway to elevate sunscreen pigments. Additional acetyl-CoA generated from pyruvate metabolism and fatty acid degradation was a key supporting factor in the above response. As high quercetin concentration was observed in both fresh and fermented leaves, this will lead to quality improvement of the fermented products.
HIGHLIGHTS

The remarkable effects of light intensities on Houttuynia cordata growth and abundance of bioactive compounds are substantial, but the underlying mechanism has never been investigated. Metabolomics technology was applied to gain insight into light-induced metabolic reconfiguration.

Published: February 2024

Radiologists find it challenging and time-consuming to recognize and evaluate nodules of lung using CT scans that are malignant. Because of this, early lung growth prediction is necessary for the inquiry technique, which raises the likelihood that the treatment will be successful. Computer-aided diagnostic (CAD) tools have been used to help with this issue. The primary goal of the work is to identify if the nodules are cancerous or not and to deliver more accurate results. The RNN [Recurrent] which is a type of neural network model that includes a feedback loop. In this paper, evolutionary algorithms are examined using the MATLAB Tool, including the Grey Wolf Optimization Algorithm and Recurrent Neural Network (RNN) Techniques. Additionally, statistical characteristics are generated and examined in comparison to other RNNs using Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) combinations. Comparing the suggested approach to other state-of-the-art techniques, it yielded results with extremely high accuracy, sensitivity, specificity, and precision. In the past few years, there has been a substantial increase for evolutionary algorithms in the field of feature selection due to their simplicity and potential for global search capabilities. The suggested solutions have outperformed classical approaches employed across various fields, showing excellent results. Determining whether lung nodules will become malignant or not will be made easier with early identification.

Published: February 2024

The text uses two tools to interpret the relationship between employee and employer. The first tool is anthropological, while the second is a legal one. In this way, the complex relationship between an employee and an employer is analyzed in the larger context of doubling the real identity of the two participants with a virtual identity for each of them. Therefore, the relationship will include two levels of reporting from the employee to the employer and vice versa. The employee will be viewed by the employer both as a natural person, therefore real, but also as a virtual person with the virtual identity or profile. In turn, the employee will refer to the employer both as a legal person and as a virtual legal person. In the following lines we propose to establish a possible ethical boundary between the employee and the employer as virtual entities capable of orienting the anthropological and legal analysis.

In order to offer students a quality internship, specialized practice should be an integrated, valuable experiential learning, relevant for their future activities. More, future students learn about university / faculty/professors’ prestige, about their opportunity to be engaged when they graduate, and learn about their internships and sometimes this internship could be an important reason for choosing a study program. So, considering university offer for a quality internship, we consider that is necessarily to also create for students the opportunity to be reflexive on their personal experiential learning. Our present study presents the opinion of our students from Petroleum – Gas University of Ploiesti, Pedagogy specialisation, considering their pedagogic and specialized practice, starting from their reflexive observation during counselling activities they have assisted / performed in high schools.

Published: February 2024

The education of a child, who represents the future adult and a responsible, emotionally intelligent citizen actively engaged in urban life, stands as a paramount concern and priority for all of us. Therefore, the foundation of this endeavor rests upon a child-centric approach, with the family, society in its narrower context, and the state serving as essential pillars of support. In this comprehensive perspective, the child occupies a central role, necessitating concerted efforts and commitment from all stakeholders. A child and future citizen must develop harmoniously physically and emotionally to be protected against any form of neglect or abuse. The societal community, within its defined scope, plays a pivotal role in shaping the environments that molds a child's development. Meanwhile, the state has the responsibility of formulating and implementing coherent measures that govern relationships and address various circumstances to ensure they do not adversely affect a child's upbringing.

Published: February 2024

The following study is based on a practical case concerning the situation of a husband and wife who, although they met all the requirements for usucapio, died without exercising this right before the court. Such facts raise the following legal questions: could their right of option to invoke the positive prescription be transferred to their heirs? Or is it necessary for the heirs to start a new possession in their own person, in order to then take advantage of the merger of possessions? The answer to these questions is not easy to deduce, as the research we conducted shows that the issue is a controversial one.
Quantifying the contribution of atmospheric circulation to precipitation variability and changes in the US Great Plains and southwest using self-organizing map–analogue
Authors: Zhuang Yizhou , Fu Rong
Published: February 2024

Abstract. The Great Plains and southwest regions of the US are highly vulnerable to precipitation-related climate disasters such as droughts and floods. In this study, we propose a self-organizing map–analogue (SOMA) approach to empirically quantify the contribution of atmospheric moist circulation (mid-tropospheric geopotential and column moisture transport) to the regional precipitation anomalies, variability, and multi-decadal changes. Our results indicate that moist circulation contributes significantly to short-term precipitation variability, accounting for 54 %–61 % of the total variance in these regions, though these contributions vary significantly across seasons. As indicated in previous research, Pacific Decadal Oscillation (PDO) is one of the major climate modes influencing the long-term multi-decadal variation in precipitation. By contrasting three multi-decadal periods (1950–1976, 1977–1998, 1999–2021) with shifting PDO phases and linking the phase shift to self-organizing map (SOM) nodes, we found that circulation changes contribute considerably to the multi-decadal changes in precipitation anomaly in terms of the mean and days of dry and wet extremes, especially for the southern Great Plains (GP) and southwest. However, these circulation-induced changes are not totally related to the PDO phase shift (mostly less than half) since internal variability or anthropogenically induced changes in circulation can also be potential contributors. Our approach improves upon flow analogue and SOM-based methods and provides insights into the contribution of atmospheric circulation to regional precipitation anomalies and variability.
Research on landslide master control factor identification and susceptibility prediction modelling
Authors: Xing Yin , Chen Yang , Wang Peng , Huang Saipeng , Xiang Yunfei
Published: February 2024

Abstract. It is important to properly identify the primary control elements of landslide susceptibility because the modelling process and its uncertainties differ between machine learning predictions of susceptibility to landslides. In response to the aforementioned issues, the novel "weight mean method" is suggested to determine more precise landslide master factors. Support vector machine (SVM) and random forest (RF) are used as examples to discuss the prediction of landslide susceptibility and its uncertainty based on machine learning. For Ruijin City, Jiangxi Province, the landslide inventory and 12 different types of underlying environmental factors were acquired, and the factor frequency ratios were employed as input variables for SVM and RF. The landslides and randomly selected non-landslide samples were then divided into training and test sets, and the trained machine learning was used to predict and map landslide susceptibility. In order to assess modeling uncertainty and determine the landslide master control factor, subject work curves, means, and standard deviations were used. The results show that: (1) Machine learning can effectively predict regional landslide susceptibility, the accuracy of landslide susceptibility predicted by RF is higher than that of SVM, while its uncertainty is lower than that of SVM, but the overall susceptibility distribution patterns of both are similar. (2) The weight-mean approach determines that the slope, height, and lithology, in that order, are the primary controlling elements of the landslide in Ruijin City. In comparison to other machine learning models, the case studies and literature study demonstrate how dependable and susceptible the RF model is.
Quantifying the Influence of Snow over Sea Ice Morphology on L-Band Microwave Satellite Observations in the Southern Ocean

Published: February 2024

Abstract. Antarctic snow on sea ice can contain slush, refrozen snow-ice and stratified layers, complicating satellite retrieval processes for snow depth, ice thickness, and sea ice concentration. The introduction of moist and brine-wetted snow alters microwave snow emissions and modifies the energy and mass balance of sea ice. This study assesses the impact of brine-wetted snow and slush layers on L-band surface brightness temperatures (Tbs) by synergizing a snow stratigraphy model (SNOWPACK) driven by atmospheric reanalysis data and a RAdiative transfer model Developed for Ice and Snow in the L-band (RADIS-L) v1.0. The updated RADIS-L v1.1 further introduces parameterisations for brine-wetted and slush snow layers over Antarctic sea ice. Our findings highlight the importance of including both brine-wetted snow and slush layers in order to accurately simulate L-band brightness temperatures, laying the groundwork for improved satellite retrievals of snow depth and ice thickness using satellite sensors such as the Soil Moisture and Ocean Salinity (SMOS) and Soil Moisture Active Passive (SMAP). However, biases in modeled and observed L-band brightness temperatures persist, which we attribute to sub-grid scale ice surface variability and snow stratigraphy. Given the scarcity of comprehensive in situ snow and ice data in the Southern Ocean, ramping up observational initiatives in the region is imperative to provide not only satellite validation data sets but also improving process-level understanding that can scale up to improving the precision of satellite snow and ice thickness retrievals.
A new dataset of rain cells generated from observations of the Tropical Rainfall Measuring Mission (TRMM) precipitation radar and visible and infrared scanner and microwave imager

Published: February 2024

Abstract. Rain cells are the most common units in the natural precipitation system. Enhancing the understanding of these rain cell characteristics can significantly improve the cognition of the precipitation system. Previous studies have mostly analyzed rain cells from a single radar data. In this study, we merged the precipitation parameters measured by the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) with the muti-channel cloud-top radiance measured by the visible and infrared scanner (VIRS) and the muti-channel brightness temperature measured by the TRMM microwave imager (TMI). The rain cells were identified within the PR orbit, and the swath truncation effect was eliminated. We used two methods for rain cell identification: the minimum bounding rectangle (MBR) method and the best fit ellipse (BFE) method, and compared the differences between these two methods in describing the rain cell characteristics. The results indicate that both methods can better reflect the geometric characteristics of rain cells. Compared with the MBR method, the BFE method can obtain a smaller rain cell area, and the filling ratio is better. However, the MBR method can simplify the data storage volume. Consequently, we employed the MBR method to analyze the precipitation structure of two typical rain cell precipitation cases. The results show that the new rain cell dataset can be used for the analysis of rain cell precipitation parameters and visible/infrared and microwave signals, which provides valuable data for comprehensive studies on the rain cell structural characteristics and furthers the understanding of precipitation mechanisms.

Published: February 2024

Abstract. China has undergone rapid urbanization and internal migration in past years and its up-to-date gridded population datasets are essential for diverse applications. Existing datasets for China, however, suffer from either outdatedness or failure to incorporate the latest seventh national population census data conducted in 2020. In this study, we develop a novel population downscaling approach that leverages stacking ensemble learning and geospatial big data to produce up-to-date population grids at a 100-m resolution for China from the seventh census data at both county and town levels. The proposed approach employs random forest, XGBoost, and LightGBM as base models for stacking ensemble learning and delineates the inhabited areas from geospatial big data to enhance the gridded population estimation. Experimental results demonstrate that the proposed approach exhibits the best fit performance compared to individual base models. Meanwhile, the out-of-sample town-level test set indicates that the estimated gridded population dataset (R2=0.8936) is more accurate than existing WorldPop (R2=0.7427) and LandScan (R2=0.7165) products for China in 2020. Furthermore, with the inhabited areas enhancement, the spatial distribution of population grids is more reasonable intuitively than the two existing products. Hence, the proposed population downscaling approach provides a valuable option for producing gridded population datasets. The estimated 100-m gridded population dataset of China holds great significance for future applications and it is publicly available at https://figshare.com/s/d9dd5f9bb1a7f4fd3734 (Chen et al., 2024).

Abstract. Aerosol particles are an important part of the Earth system, but their concentrations are spatially and temporally heterogeneous, as well as variable in size and composition.  Aerosol particles can interact with incoming solar radiation and outgoing long wave radiation, change cloud properties, affect photochemistry, impact surface air quality, and when deposited impact surface albedo of snow and ice, and modulate carbon dioxide uptake by the land and ocean. High aerosol concentrations at the surface represent an important public health hazard.  There are substantial datasets describing aerosol particles in the literature or in public health databases, but they have not been compiled for easy use by the climate and air quality modelling community.  Here we present a new compilation of PM2.5 and PM10 aerosol observations including composition, a methodology for comparing the datasets to model output, and show the implications of these results using one model.  Overall, most of the planet or even the land fraction does not have sufficient observations of surface concentrations, and especially particle composition to understand the current distribution of aerosol particles.  Most climate models exclude 10–30 % of the aerosol particles in both PM2.5 and PM10 size fractions across large swaths of the globe in their current configurations, with ammonium nitrate and agricultural dust aerosol being the most important omitted aerosol types.  The dataset is available on Zenodo (https://zenodo.org/records/10459654, Mahowald et al., 2024).

Abstract. No consensus exists about the techniques to use for microbiological diagnosis of bone and joint infections (BJIs). The objective herein was to define an algorithm to optimize BJI diagnosis in adults using various bacteriological methods on synovial fluid samples. This prospective multi-center study included 423 synovial fluids collected from adult patients with suspected BJIs. Culture (using five solid media, an enrichment broth, and blood culture bottles), universal 16S rRNA PCR followed by Sanger sequencing, and seven specific bacterial PCRs were systematically performed. Combinations of methods were compared to arrive at the optimized algorithm. Among 423 synovial fluids, 242 infections were diagnosed (57.2 %): 213 mono- and 29 poly-microbial for a total of 284 bacteria (staphylococci at 54.6 %, streptococci–enterococci at 16.5 %, Gram-negative bacilli at 15.5 %, anaerobic species at 8.8 %). Comparing culture techniques, blood culture bottles had the highest sensitivity (67.6 % for pediatric and 63.9 % for anaerobic bottles) but are not sufficient alone and require being combined with solid media. The 16S rDNA PCR detected only 52.3 % of the bacteria, whereas specific PCRs had a higher sensitivity (Staphylococcus spp. at 66.2 %, S. aureus at 85.2 %, Streptococcus spp. at 91.2 %). Based on these results, an algorithm was proposed associating three solid media; inoculation into blood culture bottles; and 16S, Staphylococcus spp., and Streptococcus spp. PCRs, which would have detected 90.5 % of bacteria in the present cohort versus 79.2 % using all culture techniques on synovial fluid. This prospective study shows that a combination of culture and molecular methods on synovial fluids allows the optimization of bacterial detection.

Abstract. This paper designed a kind of satellite deployment mechanism with a boxed structure and passive torsion joints. This deployment mechanism has significant strengths, including a high base frequency and stiffness, a high ratio of deployed and folded space occupation ratios, and self-actuated joints without needing any external power to drive. In order to analyze the dynamic characteristics of this mechanism, a simplified governing equation is proposed and dynamic behavior is studied systematically, including impact response, harmonic response, and modal analysis. Through systematic research, several conclusions are drawn. Firstly, when the deployment mechanism reached the ending stage of unfolding driven by passive torsional joints, the load base installed on top of the deployment mechanism generated a first-order sharp reaction force and multiple low-order shocks followed, and the system entered a stable state after a certain time of vibration. Secondly, the system can generate a high vibration magnitude at low-frequency excitation when the mechanism is in a fully deployed state and at high-frequency excitation when the mechanism is in a folded state. Thirdly, the first sixth-order natural frequency and vibration shape with different wall thicknesses are obtained by modal analysis. The result shows that only with a 2.5 mm wall thickness can the connecting rod satisfy the design requirement. Through dynamic behavior research, the structure characteristics are obtained which can be used for structure optimization and to provide an effective solution for the design of a box-structured satellite-unfolding mechanism with self-actuated torsion joints.

The Relationship between Resilience, Wellbeing, and Psychological Distress as Mediated by Mindfulness and Coping
Authors: Pangngay Jose J.
Published: February 2024

Determining the multifaceted antecedents of mental health and psychological distress offers valuable insights into the intricate interplay of factors that influence individuals' wellbeing. Hence, this paper aimed to assess the causal relationship of resilience to subjective wellbeing and psychological distress as mediated by mindfulness and coping. Using a non-experimental mediation design, 365 college students recruited through stratified random sampling were administered with online self-report measures measuring resilience, subjective wellbeing, psychological distress, mindfulness, and coping. Parallel mediation analysis was used to analyze the data. Results revealed that mindfulness, adaptive, and maladaptive coping partially mediated the predictive association of resilience to wellbeing. Moreover, mindfulness and maladaptive coping partially mediated the predictive association of resilience to psychological distress. These findings provide a practical framework for outcome-based resilience intervention programs where interventionists would heavily emphasize enhancing resilience, mindfulness, and adaptive coping to achieve good mental health outcomes.

Mục tiêu: Đánh giá hiệu quả điều trị bệnh trứng cá thông thường (TCTT) mức độ vừa và nặng bằng isotretinoin (ISO) kết hợp kẽm đường uống. Đối tượng và phương pháp: Thử nghiệm lâm sàng có đối chứng. 90 bệnh nhân TCTT mức độ vừa và nặng được lựa chọn ngẫu nhiên vào hai nhóm (45 bệnh nhân/nhóm), nhóm nghiên cứu (NNC) dùng ISO 20mg/ngày và kẽm 40mg/ngày, nhóm đối chứng (NĐC) chỉ dùng ISO 20mg/ngày, thời gian điều trị 4 tháng. Thay đổi về mức độ bệnh, điểm GAGS và mức đáp ứng điều trị được đánh giá trước, trong và sau điều trị để so sánh hiệu quả điều trị ở hai nhóm. Kết quả: Hiệu quả cải thiện về mức độ bệnh và mức đáp ứng điều trị, điểm GAGS đều ghi nhận ở cả 2 nhóm đối tượng sau điều trị. Tuy nhiên, NNC cải thiện mức độ bệnh và đáp ứng điều trị, điểm GAGS ở hơn 90% bệnh nhân, có sự khác biệt với NĐC sau thời gian điều trị 3 và 4 tháng. Tác dụng phụ trên lâm sàng gặp ở NĐC nhiều hơn NNC là bùng phát mụn ở tháng thứ 1 và 2 sau điều trị. Kết luận: Trong điều trị TCTT mức độ vừa và nặng, uống isotretinoin phối hợp kẽm cho hiệu quả điều trị tốt hơn so với dùng isotretinoin đơn trị liệu.
SUSTAINABLE LIVELIHOOD AND NUTRITION SECURITY FOR TRIBAL FARMERS: CASE STUDY OF WADI PROJECTS IN DUNGARPUR
Authors: VERMA RATNA
Published: February 2024

Dungarpur is a tribal-dominated district of Rajasthan. The district is exemplified by low agriculture productivity, poor irrigation sources, drought, and low infrastructural and market support to the farmers. The majority of farmers in this tribal part of the state are small and marginalized and have experienced age-old deprivation. The Dharampal Satyapal Ltd. (DS Group), as a Corporate Social Responsibility (CSR) has built a model of a three-tier system of wadi cultivation (small orchard to grow fruits and vegetables) to reduce climatic, biological, and market risks and secure livelihoods and nutrition for deprived tribal farmers' families. The study attempted to assess the PAHAL (Promotion of Agriculture and Horticulture for Advancement of Livelihood) project implemented by DS Group in Dungarpur. The exploratory study was conducted using quantitative and qualitative methods for data collection. The 24 dietary recall method and food frequency were used to understand micronutrient intake. An anthropometric data was taken to explore BMI for women and MUAC for children under five years. The study covered 100 samples from the intervention area and 100 from the non-intervention area (control group) to obtain findings based on a case-control strategy. The findings of the study indicate that wadi cultivation has dramatically increased family income through improved production of diversified crops. The family income ranges from 5000-10000 per month exclusively from the sale of wadi produce throughout the year. The availability of varied fruits and vegetables and nutrition awareness resulted in adding diversity of nutritious food to the farmers’ food basket and improved nutritional outcomes among women and children. The anthropometric data indicate the significant contribution of the project in improving nutritional outcomes among women and children of farmers’ families.

Visceral Leishmaniasis (VL) known as Kala Azar, is a gradually advancing endemic illness triggered by a protozoan belonging to the Leishmania family, particularly L. Donovani in India. Ranking as the second most significant parasitic cause of mortality globally, it follows malaria in terms of impact. This disease stands out as the world?s most overlooked, and poverty linked health challenges, predominantly affecting impoverished individuals in developing nations. Contributing factors include malnutrition, compromised immune systems, displacement, substandard housing, low literacy rates, gender disparities, and limited access to resources. The widespread across a significant global expanse, with an annual estimated incidence of 500,000 cases [1]. This leads to a significant number of 2.4 million DALYs every year. In the last century, various occurrences of Kala-azar outbreaks have affected areas in South-East Asia.

Published: February 2024

The impact of shading on selected ornamental plant species was investigated by monitoring plant growth under a nontransparent roof in a nursery in Jülich and in an AgriPV-System in Rathenow. Plants were continuously measured using different RGB camera systems. Shading led to an increase in projected leaf area, increased petiole length and specific leaf area. Morphological changes in shade-sensitive Geranium cinereum plants led to a loss of plant marketability. Flowering time of Hydrangea sp. was not affected in a long term experiment in the AgriPV-System. Pigment composition was not altered significantly in Rhododendron plants. Experiments will be continued with a local nursery in a novel AgriPV-System established near Jülich.
Agrivoltaics in Japan
Authors: Doedt Christian , Tajima Makoto , Iida Tetsunari
Published: February 2024

A comprehensive and supportive legal framework is a key factor for the expansion of agrivoltaics. This study analyzed, therefore, the existing laws, regulations, and policies related to agrivoltaics in Japan and assessed its actual effects on relevant stakeholders. An increasing horizontal policy integration on the federal level was identified. However, the vertical policy integration is still insufficient with often skeptical municipalities and local agricultural councils. The key barriers are related to the land-use conversion process, financing of agrivoltaic projects, socio-political and market acceptance, and grid constraints in rural areas. There are, however, opportunities for addressing these challenges in recently established councils that include a variety of members from industry, academia, and government.
