Authors: Polisetti Ravibabu , Lanke Sowmya , Vanipenta Teja 
Published: September 2022

<p class="abstract"><strong>Background:</strong> Hearing is necessary to learn languages and speech and to develop cognitive skills. Unfortunately, many children with severe hearing loss from birth are not diagnosed until 21/2-3 years. of age. Implementing high-risk neonatal screening, detecting hearing loss before 3 months, and intervention before 6 months will result in a better speech performance of neonates.</p><p class="abstract"><strong>Methods:</strong> Detailed history taking and general and ear, nose and throat (ENT) examination were done to rule out external ear and middle ear pathology. Brainstem evoked response audiometry (BERA) was done in a dust-free, sound-proof, airconditioned room. Feed was given 10–15 min before the procedure. Syrup pedichloryl 20 mg/kg was given to sedate the baby half an hour before the procedure. Intelligent hearing system BERA instrument was used. The study included a total of 60 infants. 30 were in the high-risk group and 30 were in the normal group. There were 14 males and 16 females in each group. </p><p class="abstract"><strong>Results:</strong> 21 infants had hearing loss out of the 30 infants in the high-risk group on initial screening. On doing a repeat BERA after 3 mins on the affected infants, 3 were detected to have normal hearing, i.e., 18 out of 30 infants were affected. All the infants in the normal or no risk factor group had normal hearing.</p><p class="abstract"><strong>Conclusions:</strong> The present study emphasizes the importance of using ABR as a screening tool for the detection of hearing impairment at an early stage which would have otherwise go unnoticed for about 2-3 years. Since it is an objective test, it is useful in the early identification of hearing loss.</p><p> </p>

Published: September 2022

<p><strong>Background:</strong> Spontaneous cerebrospinal fluid (CSF) rhinorrhoea is encountered as a diagnosis of exclusion in clinical practice once all other aetiologies have been meticulously ruled out and can mostly present from preformed pathways due to benign intracranial hypertension (BIH) over time. Such leaks need to be clearly located for planning appropriate repair along with adequate control of CSF pressure to avoid recurrence. Thus, the aim of our study was to review the efficacy and outcomes of a combined endoscopic multilayered repair along with simultaneous theco-peritoneal shunting (TPS) for patients with spontaneous CSF rhinorrhoea in the background of BIH.</p><p><strong>Methods:</strong> Retrospective observational study analyzing the clinical presentations, surgical techniques and the immediate / long term outcomes of this combined approach.</p><p><strong>Results: </strong>The<strong> </strong>46 patients who had endoscopic CSF repair with TPS done between 2008-2019 were reviewed. The mean opening CSF pressure in these cases were &gt;25 cm H<sub>2</sub>O. The commonest site of leak was from cribriform plate followed by fovea ethmoidalis. Multilayered closure was done with autologous grafts along with TPS simultaneously. The 92% were successful, 6% had shunt problems needing revision shunts and 2% also needed revision endoscopic repair. </p><p><strong>Conclusions:</strong> Overall outcomes shows that the combined approach was safe and effective in arresting the CSF leak in 98% patients. Therefore, the rationale for a combined approach for the management of spontaneous CSF leaks in the background of BIH stands proven based on our Institutional experience.</p>

Published: September 2022

Introduction: Hyperkyphosis is known to interfere with the normal function of the trunk musculature in the elderly. Although the effectiveness of orthoses in improving posture and balance in hyperkyphotic elderly people has received much attention, the effect of an orthosis on motor control of muscles remains unknown. This study aimed to evaluate changes in motor control strategies of trunk muscles during walking in elderly hyperkyphotic subjects after using an anatomical posture control (APC) orthosis.
Materials and Methods: A total of 19 elderlies (11 women and 8 men) with thoracic hyperkyphosis of more than 45 degrees were enrolled in the study. Surface electromyography (EMG) signals were recorded from 6 trunk muscles bilaterally with and without orthosis. The voluntary response index (VRI) was calculated from quantitative analysis of surface electromyography (sEMG) data during level walking in those with and without orthosis. The outcome variables of VRI included the similarity index (SI) and electromyographic magnitude (MAG) of muscle groups. The effects of APC orthosis on trunk motor control were tested using a Wilcoxon non-parametric test. Cohen’s d effect sizes were also calculated.
Results: A significant improvement was observed (P<0.05) in MAG and response vector (RV) of five muscles from the right and left sides and the VRI increased significantly after using this posture control orthosis (P<0.05; effect size [ES]: 0.27).
Conclusion: Improving trunk motor control after using orthosis, with relatively medium effect sizes, was observed in the elderly with hyperkyphosis during walking.
Riesgo para la salud asociado a la vivienda y su entorno. Propuesta metodológica para su evaluación
Authors: Grijalba Olatz , Barrena-Herrán Mikel , Modrego-Monforte Itziar 
Published: September 2022

ResumenSegún la Organización Mundial de la Salud (OMS) las condiciones morfológicas, materiales y de contexto de los edificios residenciales pueden exponer a las personas a distintos riesgos para la salud, tanto físicos como mentales. Dicho riesgo depende de factores de muy diversa índole (socioeconómica, sociocultural, ambiental, etc.). Es un fenómeno multifactorial y multicausal, donde los aspectos arquitectónicos y urbanísticos son una variable importante de un sistema complejo. Los retos a los que se enfrentan las estrategias de rehabilitación residencial deberían adaptarse para dar respuesta a las deficiencias de los distintos ámbitos. En este contexto, se ha desarrollado un método para evaluar la vulnerabilidad residencial en función al riesgo para la salud de las personas. Se trata de una primera propuesta para incorporar aspectos como la iluminación y la ventilación natural o la espacialidad o flexibilidad de las viviendas en los métodos de evaluación del parque edificado. Pretende provocar una reflexión acerca de la diversidad existente en las necesidades, en contraposición a la uniformidad de las estrategias de rehabilitación impulsadas por la Administración Pública en esta última década. A su vez, posibilita entender la estructuración del parque residencial a nivel urbano e interrelacionar aspectos tipo morfológicos y socioeconómicos e indagar en las dinámicas de vulnerabilidad urbana. El análisis se ha realizado en cuatro tipos de vulnerabilidad (espacial, ambiental, energético y socioeconómico) a través de 24 indicadores recogidos en un modelo SIG basado en la lógica difusa y la evaluación multicriterio. Se ha utilizado como base la información cartográfica y alfanumérica del catastro. La escala de trabajo y de análisis es municipal siendo la unidad de desagregación el portal. El método se ha implementado en un caso de estudio, el término municipal de Donostia-San Sebastián, aunque es exportable y adaptable a otros contextos. La propuesta metodológica desarrollada posibilita tener una visión holística del parque y comparar las afecciones en distintas áreas de estudio. Dicha información es la base para diseñar adecuadamente las intervenciones para cada contexto o tipología y definir una estrategia de escala municipal.

Begining of integration RATP model in LASER/F for thermo-radiative simulation of an urban district with vegetation
Authors: Chakkour Tarik 
Published: September 2022

Abstract
LASER/F is designed to simulate the energy budget of the urban climate. This
model has been developed for the needs of urban climate research. The framework of the
model is described in this paper. This article deals with simulating radiative fluxes and distribution
of the radiative energy in an urban canyon. Specific algorithms involving in these
computations are presented. When vegetation is present on the ground, the transpiration
is slightly underestimated using it. On the other hand, the model RATP simulates well the
spatial distribution of radiation and leaf-gas exchanges within vegetation canopies as a function
of canopy microclimate. The aim of the paper is to improve some geometric procedures
used in LASER/F in order to obtain globally a good level of performance. Coupling these
models stays chalenging and complicated. Then, we will consider the influence of urban
planning and in particular the influence of urban vegetation in the model.

Abstract
Allopolyploid genomes are divided into compartments called subgenomes that are derived from lower ploidy ancestors. In African clawed frogs of the subgenus Xenopus (genus Xenopus), allotetraploid species have two subgenomes (L and S) with morphologically distinct homoeologous chromosomes. In allotetraploid species of the sister subgenus Silurana, independently evolved subgenomes also exist, but their cytogenetics have not been investigated in detail. We used an allotetraploid species in Silurana—Xenopus calcaratus—to explore evolutionary dynamics of chromosome morphology and rearrangements. We find that the subgenomes of X. calcaratus have distinctive characteristics, with a more conserved a-subgenome resembling the closely related genome of the diploid species X. tropicalis, and a more rapidly evolving b-subgenome having more pronounced changes in chromosome structure, including diverged heterochromatic blocks, repetitive sequences, and deletion of a nucleolar secondary constriction. Basedon these cytogenetic differences, we propose a chromosome nomenclature for X. calcaratus that may apply to other allotetraploids in subgenus Silurana, depending on as yet unresolved details of theire volutionary origins. These findings highlight the potential for large-scale asymmetry in subgenome evolution following allopolyploidization.
In-vivo acaricidal efficacy of Tephrosia vogelii leaf extract against tick infestation in cattle
Authors: Jerjero Tajebe 
Published: September 2022

Abstract
A study was conducted with the objective of evaluating the in-vivo acaricidal efficacy of Tephrosia vogelii leaf extract in controlling ticks on cattle. For this experiment, forty five naturally tick infested cattle were selected and equally divided into five treatment groups of nine animals in completely randomized design. The first three groups were topically treated with 20%, 25% and 30% w/v extract, the forth group was sprayed with diazinon as positive control at a recommended dose of 1:1000 while the fifth group was left untreated as negative control. Tick counts were conducted on day0 pre-treatment and on days4 and 7 post treatment on each animal. Post-treatment quantitative assessment of tick burden revealed a significant (P < 0.05) reduction in tick load in all treated groups compared to untreated ones. The percentage tick count reduction was higher at day 7 than day 4 for all treated groups with their respective efficacy of 80.33%, 85.42% and 90% for 20%, 25% and 30% extracts and 97.67% for diazinon at day 7 post treatment. The observed tick count reductions were found to be statistically significant (P < 0.05) at all dilution levels of the extract but without significant difference (P > 0.05) among themselves. The results also revealed both time and dose dependent efficacy of the extract and its comparable effectiveness with diazinon which was an evidence suggestive of its significant anti-tick effect. Therefore Tephrosia vogelii could be recommended as effective natural tick control alternative, especially for poorly-resourced small-scale farmers in rural areas where commercial acaricides are unavailable or unaffordable.
Any positive integer n can be expressed as the sum of 3n fractions: n=[{𝟏/2+𝟏/2+…….+𝟏/2(nth term)}+{𝟏/3+𝟏/4+…….+ 𝟏(𝒏+𝟐)(nth term)}+{1/6+2/8+….+n/𝟐(𝒏+𝟐)(nth term)}

Abstract
We aim to build an expression for any positive integer fractional form with the help of a basic concept in mathematics. We know that any positive integer n (n > 1) can be expressed as the sum of two or more positive integers. Additionally, a positive integer n (n > 1) can be expressed as the sum of positive integers and also a positive integer n can be expressed as the sum of only fractions. However, our proposal is different: we can express the fractional form of any positive integer in an attractive manner. Through a certain identity, we fulfill this objective. For any integer n, by applying the identity, we can express it as the sum of 3n fractions.
Arbuscular mycorrhizal colonization of a Cd hyperaccumulator Viola baoshanensis at Baoshan Pb/Zn Mine
Authors: Zhong Weiliang 
Published: September 2022

Abstract
Despite great potential for arbuscular mycorrhizal (AM) fungi associated with heavy metals (HMs) hyperaccumulators in the phytoremediation of contaminated sites, rather limited information is available in literature about the community structure of AM fungi (AMF) in the rhizosphere of hyperaccumulators in nature. A field survey was conducted to investigate the colonization status and community structure of AMF of Viola baoshanensis, a Cd hyperaccumulator, growing at Baoshan Pb/Zn Mine. Shoot/root ratios of 1.78 for Cd, and 2.57 for Zn in V. baoshanensis indicate that these two metals were preferentially transported from roots to shoots, whereas Pb was mainly stored in roots. The roots of V. basshanensis were extensively colonized by AMF with M% of 69.1% , and A% of 46.9% , whereas mycorrhizal colonization was not affected by concentrations of Cd, Zn and Pb in the soil. 15 AMF species ( 5 Glomus, 3Rhizophagus,2 Claroideoglomus, 2 Septoglomus, and each one of Ambispora, Funneliformis, and Sclerocystis ) were identified by a morphological method. The dominant AMF genus was Glomus, showing high tolerance to excess Cd, Zn and Pb, while Glomus ambisporum and Claroideoglomus etunicatum were the most abundant species in the rhizosphere of V. baoshanensis.

Abstract
Cardiolipin is a hallmark phospholipid of mitochondrial membranes. Despite established significance of cardiolipin in supporting respiratory supercomplex organization, a mechanistic understanding of this lipid-protein interaction is still lacking. To address the essential role of cardiolipin in supercomplex organization, we determined cryo-EM structures of a wild-type supercomplex (IV1III2IV1) and a supercomplex (III2IV1) isolated from a cardiolipin-lacking Saccharomyces cerevisiae mutant at 3.2-Å and 3.3-Å resolution, respectively. Phosphatidylglycerol is located in the III2IV1 supercomplex at similar positions as cardiolipin in the wild-type supercomplex. Lipid-protein interactions in the latter are different from that observed for the former that conceivably underlies the reduced stability of supercomplexes in mutant mitochondria. Our studies provide evidence that anionic phospholipids appear to nucleate a phospholipid domain at the interface between the individual complexes, which may contribute to supercomplex stability. Destabilization of supercomplex formation by phosphatidylglycerol has significant implications for Barth Syndrome patients where mitochondrial phosphatidylglycerol levels are significantly elevated.

Published: September 2022

Abstract
In recent years, due to the development of flexible electronics, flexible sensors have been widely concerned and applied in intelligent robots, brain-computer interfaces and wearable electronic devices. We propose a low-cost and high-efficiency sensor component preparation method. The sensor Tetrathiafulvalene-Tetracyanoquinodimethane/ melamine sponge (TTMS) takes a melamine sponge as a flexible substrate and metallizes the sponge with the organic conducting molecule Tetrathiafulvalene-Tetracyanoquinodimethane (TTF-TCNQ) to construct a conductive pathway with chemical stability. We use a physical load approach to ensure the advantages of low cost and efficient manufacturing. TTMS has good mechanical stability and can withstand 8000 compressions. 1000 cycles of cyclic voltammetry scanning proved that it also had good electrical stability. TTMS can distinguish pressure changes of 100 Pa and respond quickly to pressure application and release. These TTMS can be assembled to form an array of sensors that can distinguish the position and intensity of pressure. Therefore, the excellent performance of the sensor is expected to promote the commercial application of the piezoresistive sensor.
Adaptation of inductive power transfer to small household appliances that can operate on induction heating cooktops: wireless electric kettle
Authors: SEZER CANBERK , ALTINTAŞ NİHAN 
Published: September 2022

Abstract
In this study, the adaptation of the small household electric kettle to the inductive wireless power transfer system, which will allow it to be used as a load in induction heating cooktops, is presented. In the wireless power transfer system, a transmitter coil is used in the characteristics of the coil used in domestic induction cookers. In order to successfully transfer power, the receiving side is placed on the bottom of the existing corded electric kettle. The magnetic system model consisting of aligned transmitter and receiver coils is created in the Maxwell program. In the created model, the analysis is carried out depending on the air gap and frequency, which are the variables that affect the wireless power transfer. The coil model created to examine the dynamic behavior of the system is used in the simulation of the electronic circuit. The prototype of the system is established in the laboratory and tested under different output power values. Experimental results confirm the magnetic model and simulation results. As a result, wireless power transfer is realized without loss on performance in the electric kettle. System efficiency is greater than 90% specified in the standard and the harmonic currents drawn from the mains are lower than the values determined by the standard. Moreover, the results obtained confirm the usability of the proposal on induction hobs.
A physics-based source model for real-time tephra-dispersal prediction
Authors: Ishii Kensuke , Nishijo Akira , Koyaguchi Takehiro , Suzuki Yujiro 
Published: September 2022

Abstract
A physics-based model to estimate source conditions for a tephra-dispersal model is developed. The source condition is generally expressed by a distribution of released particles along an eruption plume (referred to as source magnitude distribution" SMD).The present model (NIKS-1D) calculates the SMD and the column height for given vent conditions(e.g. mass eruption rate and magma properties) on the basis of an eruption column model below the neutral buoyancy level (NBL), a downwind gravity current model around the NBL,and a particle sedimentation model.It quantitatively reproduces the following features of the SMD for typical explosive eruptions: (1) a significant amount of coarse particles are released from the rising eruption column, whereas most of the fine particles are carried to the NBL, (2) in a downwind gravity current, the coarse particles tend to decrease more rapidly with distance from the vent than the fine particles,(3) the SMD from the downwind gravity current decreases with distance more slowly in a strong ambient wind than that in a weak ambient wind, and (4) the SMD from the downwind gravity current for eruptions with large mass eruptionrates decreases with distance more slowly than that for eruptions with smalleruption rates. NIKS-1D includes a new parameter, $\mu$, which represents the ratioof the volumetric flux at the source of the downwind gravity current to that ofthe eruption column model at the NBL. This parameter is determined by thephysics of the entrainment process around the connection between the eruptioncolumn and the downwind gravity current, and depends on the intensity oferuptions. We propose an empirical formula to calculate the value of $\mu$ as afunction of the mass eruption rate on the basis of the observation data fromthree well-studied eruption events. In a real-time tephra-dispersal predictionsystem, NIKS-1D estimates the mass eruption rate from the observed plumeheight, and calculates the SMD from the estimated mass eruption rate as asource conditions for a tephra-dispersal prediction immediately after an eruption.
