A Novel Analog Circuit Design for Maximum Power Point Tracking of Photovoltaic Panels

A new analog technique is proposed in order to track the maximum power point (MPP) of PV panels. The proposed technique uses the well-known simple functions of electronic circuits. The proposed technique is validated by applying it to boost based off grid PV system. The simulation of the PV system was done on the circuit oriented simulator Proteus-ISIS. A good efficiency of the analog technique (more than 98%) was registered. The variation of irradiation was introduced in order to study the robustness of the proposed analog MPPT technique.
Dystocia in the Standardbred Mare: A Retrospective Study from 2004 to 2020

Simple Summary In the equine species, dystocia, any impediment to normal parturition, is not frequent, but when it occurs it can quickly evolve into a critical situation. The aim of this study was to retrospectively describe the incidence, causes, categories of dystocia severity, resolution procedures and postpartum complications in Standardbred mares hospitalized in a Veterinary Teaching Hospital and evaluate the effects of dystocia on the clinical and blood parameters of their foals. In normal pregnancy, the incidence of dystocia was 4.9%. Stage II appeared significantly longer in dystocic delivery, and the occurrences of postpartum complications in mares and onset of neonatal disease in foals were more frequent after dystocia. This study also investigated, for the first time, foaling difficulty, dividing all dystocic deliveries into mild, moderate and severe dystocia. Therefore, even a short but physiologically abnormal delivery can pose a risk to the life of the newborn and determine complications in the mare. Abstract Dystocia as a prolonged stage II parturition (>30 min) was associated with a higher risk of complications. The hypothesis of the study was that any type of dystocia could affect the foal’s health, even when the stage II was <30 min. Clinical reports on 222 Standardbred mares and their foals hospitalized at the Veterinary Teaching Hospital of the University of Bologna from 2004 to 2020 were reviewed. Mares were divided into the Eutocia Group (165, eutocic delivery) and the Dystocia Group (57, dystocic delivery). The incidence of dystocia was 4.9%. Stage II was longer in the Dystocia Group (median 20 min) than in the Eutocia Group (median 12 min). All occurrences of dystocia were retrospectively classified into three categories of severity: mild, moderate and severe dystocia. The occurrence of postpartum complications in mares and neonatal diseases and failure of passive transfer of immunity in foals was higher in the Dystocia Group. Foal venous lactatemia and serum creatine kinase were significantly higher in the Dystocia Group (median 3.9 mmol/L; 262 UI/L respectively) than in the Eutocia Group (median 3.1 mmol/L; 187 UI/L respectively). The APGAR score was lower in the Dystocia Group (median 8) than in the Eutocia Group (median 10) and significantly lower in severe dystocia (median 3). The duration of stage II should not be considered the only parameter of dystocia in mares: even a rapid resolution of dystocia could pose health risks to the foal and the mare.
Effect of injection laryngoplasty material on outcomes in pediatric vocal fold paralysis

Background While injection laryngoplasty is becoming increasingly common in children, there has not been clearly established guidelines for the choice of injection material. This study evaluates for variability in post-surgical outcomes between different materials used for injection laryngoplasty in the treatment of pediatric unilateral vocal cord paralysis. Methods In this cohort study, a retrospective chart review was performed for all patients undergoing injection laryngoplasty for unilateral vocal cord paralysis at our tertiary-care children’s hospital between January 2010 and December 2019. Patients with vocal cord paresis or bilateral vocal cord paralysis were excluded from this study. Demographics, pre- and post-injection clinic visits, and operative reports were reviewed to compare outcomes between injection materials, including the number of injections required, inter-surgical interval, and rate of vocal improvement. Results Forty-four patients were included in the analysis. Half of the patients were female, and half were male. A total of 97 injections were observed, with 32 patients receiving multiple injections. The mean age at first injection was 7 years. The most common causes of vocal fold paralysis were iatrogenic (n=21, 48%) and idiopathic (n=9, 20%). Thirty-nine percent (n=17) had a history of cardiac surgery. Forty-five percent of injections used Radiesse® voice/Prolaryn® plus, 35% used Radiesse®/Prolaryn® voice Gel, and 20% used Cymetra™. The material used was not associated with a difference in post-operative outcomes, including number of injections, (P=0.10; 0.29), inter-surgical interval (P=0.27; 0.29), or rate of voice improvement (P=0.86; 0.36). Conclusions Neither material choice nor demographic factors were associated with a difference in outcomes following injection laryngoplasty or a change in the inter-surgical interval. Further research is needed to develop standardized protocols for injection laryngoplasty in this population.
Overview of magnetless brushless machines

Owing to the definite merits of high-efficiency and high-power density, the permanent-magnet (PM) brushless machines have been dominating the high-performance industrial applications. However, the problems of high PM material cost, fluctuating supply of rare-Earth materials and ineffective PM flux control have hindered the widespread applications of the PM brushless machines. In recent years, many attentions have been shifted to the magnetless candidates, while the focuses are mainly placed on the classical candidates. In this study, an overview of magnetless brushless machines including both the classical and advanced types is presented, with emphasis on their machine topologies, features and performances. In addition, the upcoming trend of these machines is reviewed and discussed.

GREENING THE GRID: Pathways to Integrate 175 Gigawatts of Renewable Energy into India’s Electric Grid, Vol. I—National Study EXECUTIVE SUMMARY

Author(s): Palchak, D; Cochran, J; Deshmukh, R; Ehlen, A; Soonee, S; Narasimhan, S; Joshi, M; McBennett, B; Milligan, M; Sreedharan, P; Chernyakhovskiy, I; Abhyankar, N | Abstract: The use of renewable energy (RE) sources, primarily wind and solar generation, is poised to grow significantly within the Indian power system. The Government of India has established an installed capacity target of 175 gigawatts (GW) RE by 2022 that includes 60 GW of wind and 100 GW of solar, up from current capacities of 29 GW wind and 9 GW solar. India’s contribution to global efforts on climate mitigation extends this ambition to 40% non-fossil-based generation capacity by 2030. Global experience demonstrates that power systems can integrate wind and solar at this scale; however, evidence-based planning is important to achieve wind and solar integration at least cost. The purpose of this analysis is to evaluate the operation of India’s power grid with 175 GW of RE in order to identify potential cost and operational concerns and actions needed to efficiently integrate this level of wind and solar generation.
Neural Differentiation Potential of Mesenchymal Stem Cells Enhanced by Biocompatible Chitosan-Gold Nanocomposites

Chitosan (Chi) is a natural polymer that has been demonstrated to have potential as a promoter of neural regeneration. In this study, Chi was prepared with various amounts (25, 50, and 100 ppm) of gold (Au) nanoparticles for use in in vitro and in vivo assessments. Each as-prepared material was first characterized by UV-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), scanning electron microscopy (SEM), and Dynamic Light Scattering (DLS). Through the in vitro experiments, Chi combined with 50 ppm of Au nanoparticles demonstrated better biocompatibility. The platelet activation, monocyte conversion, and intracellular ROS generation was remarkably decreased by Chi–Au 50 pm treatment. Furthermore, Chi–Au 50 ppm could facilitate colony formation and strengthen matrix metalloproteinase (MMP) activation in mesenchymal stem cells (MSCs). The lower expression of CD44 in Chi–Au 50 ppm treatment demonstrated that the nanocomposites could enhance the MSCs undergoing differentiation. Chi–Au 50 ppm was discovered to significantly induce the expression of GFAP, β-Tubulin, and nestin protein in MSCs for neural differentiation, which was verified by real-time PCR analysis and immunostaining assays. Additionally, a rat model involving subcutaneous implantation was used to evaluate the superior anti-inflammatory and endothelialization abilities of a Chi–Au 50 ppm treatment. Capsule formation and collagen deposition were decreased. The CD86 expression (M1 macrophage polarization) and leukocyte filtration (CD45) were remarkably reduced as well. In summary, a Chi polymer combined with 50 ppm of Au nanoparticles was proven to enhance the neural differentiation of MSCs and showed potential as a biosafe nanomaterial for neural tissue engineering.
Intonation system of the Surgut dialect of Khanty

This paper aims to present the main features of the intonation system of the Surgut dialect of Khanty. The analysis of five folklore texts narrated by one native speaker distinguished three main intonation constructions (IC). The first one (IC-1), with a rising-falling tone, is typically used to mark the rheme (focus) and the end of the utterance, though its usage can vary depending on the tone level in its final part. The second (IC-2) and the third (IC-3), characterized by even and rising tone, are used on non-contrastive and contrastive themes accordingly. The intonation of utterances is shown to correlate strongly with their syntactic structure. In particular, intonation participates in the formation of complicated syntactic structures, with the IC-1 marking the detached components. Intonation is also used to express the relation between clauses: while communicatively and syntactically homogeneous, non-subordinate clauses are pronounced with IC-1, subordinate clauses are marked by IC-2. In addition, the role of intonation in forming the communicative structure of an utterance is considered. With the word order and communicative structure of Khanty relatively rigid, intonation is used mainly to mark the boundaries between the communicative components of utterances instead of marking their theme and rheme. Even in such cases, intonation is secondary to morphological means of expressing the communicative roles of noun phrases. Due to the limited research material, this work does not claim to be a complete description of the intonation system under consideration. How-ever, the results may serve as a basis for future research.
Online Troll Reviewer Detection Using Deep Learning Techniques

The concentration of this paper is on detecting trolls among reviewers and users in online discussions and link distribution on social news aggregators such as Reddit. Trolls, a subset of suspicious reviewers, have been the focus of our attention. A troll reviewer is distinguished from an ordinary reviewer by the use of sentiment analysis and deep learning techniques to identify the sentiment of their troll posts. Machine learning and lexicon-based approaches can also be used for sentiment analysis. The novelty of the proposed system is that it applies a convolutional neural network integrated with a bidirectional long short-term memory (CNN–BiLSTM) model to detect troll reviewers in online discussions using a standard troll online reviewer dataset collected from the Reddit social media platform. Two experiments were carried out in our work: the first one was based on text data (sentiment analysis), and the second one was based on numerical data (10 attributes) extracted from the dataset. The CNN-BiLSTM model achieved 97% accuracy using text data and 100% accuracy using numerical data. While analyzing the results of our model, we observed that it provided better results than the compared methods.
Time Spent in a Maternity Pen during Winter Influences Cow and Calf Behavior in Pasture-Based Dairy Systems

Simple Summary One of the major challenges of spring calving pasture-based systems in temperate regions is the exposure of periparturient dairy cows and their newborn calves to cold and wet winter conditions. We investigated whether moving precalving cows from an outdoor paddock to an indoor maternity pen affects the behavior of the cow and her newborn during winter and if this was influenced by the timing relative to calving. Our results indicated that cows housed in a maternity pen spent more time lying and ruminating compared with cows kept in an outdoor paddock. Moreover, newborn calf vitality improved when cows were moved to a maternity pen 3 weeks before calving when compared with those moved during the week before calving or those that remained in an outdoor paddock precalving. This information may aid in the design of calving management systems that can minimize any negative effects of inclement winter weather on cow and calf welfare in seasonal, year-round pasture-based systems. Abstract Our study compared the behavior of prepartum dairy cows that either remained in an outdoor paddock until calving (OP) during winter or were moved to an indoor maternity pen either early (EM) or late (LM) relative to calving. Forty-two multiparous Holstein cows were divided into three treatments (OP, EM, or LM) and monitored from 3 weeks before to 1.5 h after calving. Cows in EM and LM were moved to a maternity pen starting at week three and week one before the expected calving date, respectively. We assessed the cleanliness of the cows at calving, immunoglobulin G concentration in colostrum, and the behavior and vitality of calves across treatments. Cows spent more time lying in EM compared to OP and LM during the weeks −3 and −2 relative to calving, but lying time was increased in LM cows compared with OP cows during the week −1 relative to calving. Prepartum rumination time was lowest in OP cows but not different between EM or LM. Calves from OP cows spent more time lying and had lower vitality after calving than those from LM and EM cows, respectively; calves from EM and LM cows were intermediate for lying and vitality, respectively, but did not differ from either group. The cleanliness was greatest in cows that calved indoors (EM or LM); nevertheless, precalving management did not affect the IgG concentration in colostrum. Our study demonstrates that, in comparison with OP, EM and LM have positive implications for the welfare of the dam and its newborn calf during winter.
Proportion and Pattern of Epithelial Cell Abnormalities in Cervical Smears- A Retrospective Study

Introduction: Cervical cancer is a leading cause of mortality and morbidity among women worldwide. Approximately, 90% deaths due to cervical cancer occur in developing countries like India. Papanicolaou (Pap) smear test is an efficient, cost-effective screening tool to identify epithelial abnormalities in the preinvasive and early invasive stages of cervical cancer. Knowledge of the proportion and pattern of abnormal Pap smears in the local population is essential to ensure the early detection and treatment of precancerous lesions of cervix, thereby reducing the morbidity and mortality resulting from cervical cancer, which at present is preventable to a large extent. Aim: To estimate the proportion of cervical epithelial abnormalities in the local population and describe the morphological patterns of abnormalities employing the 2014 revised Bethesda system. Materials and Methods: This was a retrospective, hospital record- based descriptive study conducted in a tertiary care centre in Kerala, India from January 2016 to December 2018. Altogether, 9330 cervical smears stained using Pap method were retrieved from slide archive and evaluated. Data was collected from case notes, request forms and cytology registers. Morphological analysis was done using the revised 2014 Bethesda system. Proportion of smears showing epithelial cell abnormalities and categories of epithelial abnormalities were expressed as percentages. Results: A total of 9330 samples were studied. The proportion of epithelial abnormalities was 1.70%, of which Atypical Squamous Cells of Undetermined Significance (ASCUS) was the most frequent (1.38%), followed by Atypical Squamous Cells cannot exclude an High-grade squamous intra epithelial lesion (Atypical squamous cells-H) [HSIL (ASC-H)] (0.13%). Women with epithelial abnormalities belonged to a wide age range of 31-70 years, with majority in the 41-50 years age group. Most of the patients with abnormal Pap smears (62.3%) had normal looking or unremarkable cervix. Conclusion: The proportion and pattern of cervical epithelial abnormalities in the local population of Kerala is comparable to that of developed nations. Patients for cervical cancer screening cannot be selected based on clinical features or appearance of cervix. Even in the absence of gynaecologic complaints, screening for cervical cancer must be done at regular intervals and Pap smear test should be employed as a routine screening procedure for all women above 30 years of age. Special measures need to be taken to ensure that postmenopausal females are screened for cervical cancer.
Multiple-Vessel-Based Blood Gas Profiles Analysis Revealed the Potential of Blood Oxygen in Mammary Vein as Indicator of Mammary Gland Health Risk of High-Yielding Dairy Cows

Simple Summary The objective of the study was to realize the function of blood gas parameter in relation to the health of high-yielding dairy cows. The study showed that most blood gas parameters differ across the three vessels (coccygeal artery, coccygeal vein, and mammary vein). The associations of oxygen-related variables in the mammary vein are negatively correlated with the levels of malondialdehyde, lactate dehydrogenase, and plasmin in the milk. In the present study, we used blood gas profile to identify the mammary gland health condition in lactating dairy cows. Abstract The blood gas profile is a routine method in the rapid disease diagnosis of farm animals, yet its potential in evaluating mammary health status of dairy cows remains to be investigated. This study was conducted to learn the potential of the blood gas parameter regarding the mammary gland health status in lactating dairy cows. Twenty animals were divided into two groups, the H-SCC group (milk SCC > 122 k/mL) and L-SCC group (milk SCC < 73.8 k/mL), to compare blood gas profiles from different blood vessels and to identify the key parameters associated with milk somatic cell count. H-SCC cows are higher in malondialdehyde content, but lower in SOD and T-AOC activities in the milk, compared to the L-SCC group. In terms of blood gas parameters, most differ across the three vessels, including K+, CO2 pressure, O2 pressure, HCO3−, base excess in the extracellular fluid compartment, and saturation of O2. The Pearson correlation analysis showed that oxygen-related variables in the mammary vein, including oxygen concentrations, O2 pressure, and saturation of O2, are negatively correlated with levels of malondialdehyde, lactate dehydrogenase, and plasmin in the milk. Our study revealed that oxygen-related variables in the mammary vein can be a marker in suggesting mammary-gland health status in high-yielding cows.
Effectiveness, Attractiveness, and Emotional Response to Voice Pitch and Hand Gestures in Public Speaking

Some non-verbal cues, such as voice pitch and gestures, can influence the individual's emotional response to different messages. For this reason, non-verbal communication can be understood as the language of emotion, while the content is the language of ideas. But the research question here is what voice pitch and hand gesture strategies are more effective, attractive, and elicit a stronger emotional response. To answer this question, this study analyzes some pitch and hand gesture strategies in public discourses. In the experiment, 120 participants were exposed to different public presentations with three conditions for voice pitch (few, medium, and many variations) and three for hand gestures (smooth, medium, and strong intensity). Then, they rated the effectiveness and attractiveness levels and self-report arousal and valence while their emotional response was registered. Physiological arousal was measured with electrodermal activity (EDA) and valence with facial expression recognition. Participants perceived the medium pitch variations and the medium intensity of gestures as the most effective and attractive strategies with the highest self-reported arousal and valence. The combination that elicited the strongest autonomic arousal was medium pitch variations-strong gestures. Finally, the most positive emotional valence was for many pitch variations and medium gestures and the happiest for the combination many-strong.
Examination and Evaluation of Oyster Shell Utilization with Rice Husk Biochar for Phosphorus Adsorption

Calcium (Ca)-loaded biochar was produced from rice husks by loading the Ca source with subsequent carbonization and was examined from the evaluation of P adsorption capability about the loading method, the availability of oyster shells as the alternative, and the effect of carbonization temperature. Ca-loaded biochar prepared at 650°C had the CaCO3 form, and that at 400°C had unconverted Ca(OH)2 with less CO2 generation. Moreover, silicon in the rice husks might have existed as an amorphous structure of calcium silicate hydrate by reacting with Ca. As the loading method of the Ca source, the powder mixing method was as effective as the conventional impregnation method. It was clarified that oyster shells can be used by decarboxylation and hydration in the powder mixing method, and that the chemical form of the Ca source is important for improving P adsorption capability. Furthermore, the Ca-loaded biochar prepared at 400°C as the condition that could be performed at the paddy field location was higher P adsorption capability than that at 650°C, even though the pores were not developed. The formation of Ca(OH)2 by low-temperature carbonization of rice husks with Ca affected the improvement of P adsorption capability.
