Penile calciphylaxis is a rare complication of end-stage renal disease, & occurs as a manifestation of calcic uremic arteriolopathy, leading to necrosis and gangrenous changes in the penis. Also, penile calciphylaxis is a late manifestation in the course of end-stage renal disease, and potentially a forerunner of more sinister events to follow, such as mortality. Despite the rich vascular supply of the penis, this uncommon affectation of the penis by uremic arteriolopathy is an intriguing entity for urologists & nephrologists alike, and no formal management protocol or guidelines exist for successful management of such cases. We present 2 such cases of penile calciphylaxis which were managed at our institution

Published: May 2023

Mosquitoes are insects that vector many of the life threatening diseases. Control of these insects is one of the major problems of the world today. Leaves and seed kernel extracts of Tobacco; Nicotiana tabacum (L.) and Thorn-Apple; Datura metel (L.) were assayed for larvicidal activity against three mosquito species of Aedes, Anopheles and Culex respectively. Samples of the three species were collected from mosquito breeding sites and reared in the laboratory for continued source of larvae following standard procedures. The plants parts used were extracted with hexane, chloroform and methanol in increasing order of polarity. Each extract was formulated into 0.9, 1.6, 2.4, 3.5 and 4.0mg/mL concentrations, and tested for larvicidal activity against 25 larvae of each genus in three replicates, alongside the controls over 12 to 72 hrs periods. The extracts that exhibited highest larvicidal activity were subjected to phytochemical screenings for searching active ingredients. Data were analyzed using Analysis of Variance, treatment means separated through DNMRT and lethal concentrations of the extracts were determined. Among the extracts tested, hexane extract of D. metel and methanol extract of N. tabacum caused highest larvicidal activity with more than 70% mortality on Aedes and Anopheles larvae when 4.0mg/mL was applied after 72 hrs (LC50 2.94±0.1 and LC502.58±0.1 mg/mL respectively). Culex larvae were less susceptible to all concentrations of the extracts. Though, larvicidal activity was observed to be directly proportional to concentrations and larval exposure periods, significant differences (p< 0.05) in the means of larval death were observed. The active extracts were found to contain alkaloids, saponins steroids, flavonoids and glycosides from moderate to high quantity which could be responsible for larvicidal activity. Future formulation studies, toxicity profile and possible mechanism of action may lead to the development of potential insecticidal products.

Different strategies had been used for controlling the pest and stabilizing the productivity of the cropping systems. Weeding and insecticide application are some of the crop management practices that minimize the incidence and damage of insect pests in eggplant crops in order to enhance its growth and yield performance. Eggplant (Solanum melongena L.) is a popular and very important vegetable crop that is infested and damaged by arthropod pests in Nigeria. Field experiments were conducted to evaluate the of weeding frequency and conventional insecticide application in the control of leaf roller (Eublemma olivacea Wlk.) in eggplant. Five application concentrations of magic force (0.0, 0.5, 1.0, 1.5, and 2.0L/ha) and four weeding frequencies were assessed using split- plot laid out in randomized complete block design (RCBD) replicated three times. Results showed that three weedings and the application of insecticide at 1.5l/ha were found to be effective in reducing the population of E. olivacea and eggplant leaves damage. It further showed that these practices improved the number of eggplant fruits, fruit weight and fruit yield during the 2019 and 2020 cropping seasons in the study area combining three weedings with an appropriate insecticide (1.5l/ha) concentration rate is recommended for the control of eggplant leaf roller (E. olivacea) to poor resource farmers in the study area.

Yam (Dioscorea species) is an annual root-tuber crop with social and economic significance in terms of food security, cash returns and human health, which has social and economic importance in terms of food, cash and medicine. Insect pests present major constraints to production, storage and marketing resulting in yield and revenue reduction, and deterioration of tuber quality in storage. This study was thus designed to assess yam storage practices by the farmers and the prevalence and economic impacts of the yam scale insect, Aspidiella hartii in selected locations of Nasarawa state, Nigeria. A multi-stage sampling technique was used to select 60 yam farmers from the study area. The first stage involved random selection of four Local Government Areas (LGAs) out of the five in the study area. The second stage was the purposive selection of three villages from each of the selected LGAs while the 3rd stage was random selection of five yam farmers from each of the 12 selected villages who were interviewed using a pretested structured questionnaire. Data collected were analyzed using descriptive statistics. Results showed that the common yam storage structures were open sheds, under tree canopies, and field barns with varied dimension of 5-10 m2. Most respondents (98.3%) affirmed the presence of the yam scale insects on stored yams on those stored in the open, barns and stores, with increased incidence with extended duration in storage. Significant reduction of 36% – 50% in the market value of yam due to infestation of the yam scale insect was reported under all storage conditions. Many respondents (60%) recognized misuse and abuse as consequences of pesticide application thus, creating the need for farmers to adopt more environmentally friendly storage practices for management of the yam scale insect in the study area.
Accurate and Fast Damage Thickness Estimation in Concrete Using Smartphone-Mounted Handheld GPR and Spectrum Pattern Matching
Authors: Mizutani Tsukasa , IWAI Shunsuke
Published: May 2023

Smartphone-Mounted Handheld GPR are used to detect rebar, but quantitative detection of damage is difficult due to small reflectance. In this study, we propose an algorithm to quantitatively estimate damage thickness from received waveforms obtained from electromagnetic radar. A simple estimation method that separates peaks from above and below the crack from the time waveform is extremely difficult due to the presence of subtractive interference and side lobes. Therefore, we focus on the amplitude spectrum with the phase information dropped and estimate the damage thickness by pattern matching with a rigorous theoretical spectrum that takes multiple reflections into account. Rough damage thickness is determined by first combining multiple centroids of amplitude intensity and low-frequency components, and then spectral pattern matching is performed within the gating and bandwidth ranges set for each region, which also contributes to improving processing speed. As a result, damage thicknesses from 2 mm to 180 mm could be quantitatively estimated with a single algorithm in the 0.001 second range, confirming the practical feasibility of this algorithm.
Fully Automated Millimeter-Order Depth Estimation in Concrete Using Smartphone-Mounted Handheld GPR and Curve Fitting Techniques
Authors: Mizutani Tsukasa , IWAI Shunsuke
Published: May 2023

Smartphone-mounted handheld GPR are mainly used for detecting rebar and are attracting attention in the field of infrastructure maintenance. However, the information obtained by electromagnetic wave radar is the round-trip propagation time of electromagnetic waves from the transmitting antenna to the receiving antenna, which requires estimation of the relative permittivity in the medium to be converted into distance information. In this study, we propose a method for estimating relative permittivity and depth that takes advantage of curve reactions generated from any reflective object, including rebar and cracks. First, we confirmed that the relative permittivity can be estimated with practicable accuracy by curve fitting, in which theoretical and measured curves are observed. Next, we proposed an algorithm that automatically extracts the range to be fitted, making it possible to obtain the relative permittivity and the depth to be estimated simultaneously. As a result, we succeeded in estimating the relative permittivity with high accuracy on the millimeter-order of less than 5% error in the 0.1 second range.

On the Shielding Effectiveness of Anti-Electromagnetic-Radiation Clothes for Pregnant Females
Authors: Dehrouyeh Fatemeh , Aliakbarian Hadi , Asadi Reza
Published: May 2023

Fetal health during pregnancy is one of the most common concerns today. Some of these concerns are due to electromagnetic (EM) radiations. Thus various products are offered to protect the fetus from damage by electromagnetic radiation. One of these products is the Anti-Electromagnetic-Radiation pregnancy band - a shawl-type band which the mother wraps around her belly to protect the fetus against EM radiation. In this paper, the effects of these bands are studied to investigate how effective they are in protecting against electromagnetic waves. In order to show the effectiveness of such bands, different scenarios of using them are considered. By simulating the mother’s belly, it is shown that in some cases, it can have even opposite effects and increase the level of electromagnetic waves. To better illustrate the concept, an exemplary phantom of the mother’s belly is made, and measurements are performed on it. Simulations show that the total average field of all the scenarios in the ideal case where the shielding has no seams, at three main frequencies (0.9, 1.8, and 2.4 GHz), does not decrease more than 30 percent after using these bands, and the maximum electric field increases in more than 90 percent of the considered situations after using the band.

Efficient Multiple Scattering Solutions to Radiative Transfer Equations in Strong Forward Scattering Environments for Vegetated Land Emission and Its Parameterization through The Albedo-Tau Formalism
Authors: chen kaiqi , Tan Shurun
Published: May 2023

The Radiative Transfer (RT) theory has been widely utilized for wave propagation in random media, but it faces challenges in situations involving strong forward scattering, such as in forests with electrically large trunks, due to the singularity of the scattering phase matrix. In this paper, we present an effective approach to compute multiple scattering solutions to RT equations with singular phase matrix by combining the strategy of forward scattering extraction with an efficient numerical iterative procedure through interpolation. We evaluate the effectiveness and efficiency of our technique through simulations using a layer of vertically oriented, electrically large long cylinders to represent a layer of trunks over the ground. The results demonstrate that the proposed approach increases the computational efficiency by one to two orders of magnitude in cases where forward scattering is dominant. Additionally, a parameterized model is derived by matching the higher-order RT results with the ω − τ formalism under catered conditions. An explicit physical definition of the equivalent scattering albedo and equivalent optical thickness are proposed under boundary-free conditions. The multiple scattering effects are included in the physically derived equivalent parameters of the plant layer, which are independent of ground conditions by definition. Tests verify that the applicability of the parameterized model with ω−τ form can be extended to a wider range of vegetation and ground conditions. Besides, these equivalent parameters are directly linked to the geometric structures and electromagnetic properties of the vegetation layer, allowing their values to be frequency- and angle-dependent. Compared to the single-scattering albedo and optical thickness, the effective albedo derived from the RT model exhibits relatively weak polarization and angle dependence. This is consistent with many empirically derived parameterizations while providing a physically plausible origin for these equivalent parameters. Remarkably, we find that the transmittance linked to the parameterized tau value, incorporating multiple scattering effects, is similar to that obtained through full-wave simulations.

A Data-Centric Approach for Object Recognition in Hemispherical Camera Images
Authors: Balgabekova Zarema , Alaran Muslim , Varol Hüseyin Atakan
Published: May 2023

Object recognition is a machine learning problem that involves the correct classification and localization of objects in an image. Object recognition has found wide applications in Industry 4.0, surveillance, and autonomous driving. Prominent datasets such as Pascal VOC, ImageNet, and MS COCO have further spurred advances in object recognition. However, the images in these datasets were captured using ordinary perspective lenses. Unlike ordinary cameras, fisheye or hemispherical cameras have a wide FoV reaching 180 degrees. Due to this property, they can acquire wide panoramic images, thus, capturing more objects in a scene as compared to ordinary perspective lenses. In this work, we provide the first benchmark testing dataset of real fisheye images containing commonly-occurring objects in the human environment obtained with hemispherical cameras. The dataset comprises 1,000 images containing 39 classes with a total number of 14,218 object instances. We trained the YOLOv7 model on the original MS COCO and transformed FisheyeCOCO datasets and tested the obtained models with our dataset. The results indicate that training the model on the combination of original and transformed datasets improves the performance by 2.5% compared to using these datasets separately.

Published: May 2023

To communicate, speech impaired people use hand signs and gestures. The ordinary people are faced with difficulties in knowing what they're attempting to communicate. There's a lot of systems that are converting information to Hindi, but it's very rare. It is therefore necessary to introduce a system whereby all signs, gestures and messages can be recognised and communicated to the general public. It will bridge the gap between people with speech impairments and ordinary folk.Recognition of sign language and learning are the main research methods based on human interaction with computers. For data transfer to be recognised in sign language, multiple sensors are needed. In this Research Paper, the design of a training tool in Hindi that senses an image is targeted at those who are impaired with their speech and thus provides information as to what another person wishes to communicate.

European Commission has recently published the rules on the use of the quality term "mountain product". The new regulation aims to promote the sustainable development of mountain areas and to facilitate the identification of mountain products by consumers. Despite the importance of viticulture for several European mountain communities and the growing interest of European consumers in quality certified foods, the regulation did not encompass wines. The literature addresses many issues regarding wines and consumer preferences, but so far mountain wines are not specifically researched. With this study, we seek to fill this gap by analysing Italian consumers’ preferences for mountain wines as well as their opinion on the inclusion of this product in the mountain labelling scheme. To do so, this study applies a best-worst scaling model and subsequent latent class analysis. Data was collected through an online questionnaire applied to a consumer panel. The results indicate that most of respondents are in favour of applying the mountain label to wines. The three most preferred attributes are related to human health, ecological sustainability and product typicity. Most of the participants gave less importance to the attributes that characterize mountain agriculture. Only one consumer segment valued some of these. The findings suggest that the inclusion of mountain wines in the labelling scheme may increase the interest of Italian wine consumers, especially if health, sustainability and typicity are ensured by producers.

Published: May 2023

Aim: In this study, we aimed to examine the expression levels of Adrenomedullin (ADM) and soluble fms-like tyrosine kinase-1 (sFlt-1), two novel proteins found to be involved in vascular regulation in gestational diabetes mellitus (GDM), to compare the expression levels of these proteins in the histopathology of the disease and to observe the correlation of the expression intensity of these proteins with the disease.

Methods: In our study, 20 healthy and 20 GDM placenta samples were obtained. Histologic follow-up was performed. 5µm thick sections were taken from these tissues and stained with Hematoxylin-Eosin and Periodic Acid Schiff (PAS). Immunohistochemically, ADM and sFlt-1 antibodies were studied.

Results: In the GDM group, vascular dilatation and congestion in stem villus, hyperplasic endothelial cells, and increased syncytial bridges in the external part of the villi, mononuclear cell infiltration, pyknotic nuclei and cytoplasm loss in some of the decidual cells in the maternal region were observed. In the immunohistochemical examination, cytotrophoblast and syncytiotrophoblast cells of villous and syncytial nodes showed negative ADM expression. ADM was positively expressed in some cytotrophoblast cells of small villi, vascular endothelial cells and decidual cells. In the GDM group, sFlt-1 expression was positive in endothelial cells, some Hofbauer cells of mesenchymal connective tissue, decidual cell nuclei and membranes.

Conclusion: ADM may be an important receptor in insulin metabolism to determine the glucose level because we found positive ADM expression in cytotrophoblasts and membranes of decidual cells. In addition, changes in endothelial cells of maternal and fetal regions and sFlt-1 expression in Hofbauer cells suggest that this molecule possibly plays a key role in the angiogenic effect.
