On the Possibility of Generalized Wormhole Formation in the Galactic Halo Due to Dark Matter Using the Observational Data within the Matter Coupling Gravity Formalism
Authors: Mustafa G. , Maurya S. K. , Ray Saibal
Published: December 2022

In this article, we find the possibility of generalized wormhole formation in the galactic halo due to dark matter using observational data within the matter coupling gravity formalism. Keeping this as a target, we specifically employ f(R, T) gravity with (i) a variational approach concerning the metric, and (ii) the anisotropic source of matter. To understand the features of the wormholes, we thoroughly calculated and analyzed the energy conditions under f(R, T) gravity. We discuss the second embedded wormhole solution, known as the generalized Ellis–Bronnikov spacetime (ultrastatic wormhole model), in terms of the tortoise coordinate. Thereafter we generate and compare different wormhole solutions depending on the parametric values. In the second part of our investigation, we presented dark matter halos and provided interesting features by considering a couple of profiles. For the dark matter halos models, we particularly use the observational data of the M87 galaxy and the Milky Way galaxy.

Published: December 2022

Prestellar cores, the birthplace of Sun-like stars, form from the fragmentation of the filamentary structure that composes molecular clouds, from which they must inherit at least partially the kinematics. Furthermore, when they are on the verge of gravitational collapse, they show signs of subsonic infall motions. How extended these motions are, which depends on how the collapse occurs, remains largely unknown. We want to investigate the kinematics of the envelope that surrounds the prototypical prestellar core L1544, studying the cloud-core connection. To our aims, we observed the HCO+ (1–0) transition in a large map. HCO+ is expected to be abundant in the envelope, making it an ideal probe of the large-scale kinematics in the source. We modeled the spectrum at the dust peak by means of a nonlocal thermodynamical equilibrium radiative transfer. In order to reproduce the spectrum at the dust peak, a large (∼1 pc) envelope is needed, with low density (tens of cm−3 at most) and contraction motions, with an inward velocity of ≈ 0.05 km s−1. We fitted the data cube using the Hill5 model, which implements a simple model for the optical depth and excitation temperature profiles along the line of sight, in order to obtain a map of the infall velocity. This shows that the infall motions are extended, with typical values in the range 0.1–0.2 km s−1. Our results suggest that the contraction motions extend in the diffuse envelope surrounding the core, which is consistent with recent magnetic field measurements in the source, which showed that the envelope is magnetically supercritical.

Black Hole Images as Tests of General Relativity: Effects of Plasma Physics
Authors: Özel Feryal , Psaltis Dimitrios , Younsi Ziri
Published: December 2022

The horizon-scale images of black holes obtained with the Event Horizon Telescope have provided new probes of their metrics and tests of general relativity. The images are characterized by a bright, near-circular ring from the gravitationally lensed emission from the hot plasma and a deep central depression cast by the black hole. The metric tests rely on the fact that the bright ring closely traces the boundary of the black hole shadow with a small displacement that has been quantified using simulations. In this paper we develop a self-consistent covariant analytic model of the accretion flow that spans a broad range of plasma conditions and black hole properties to explore the general validity of this result. We show that, for any physical model of the accretion flow, the ring always encompasses the outline of the shadow and is not displaced by it by more than half the ring width. This result is a consequence of conservation laws and basic thermodynamic considerations and does not depend on the microphysics of the plasma or the details of the numerical simulations. We also present a quantitative measurement of the bias between the bright ring and the shadow radius based on the analytical models.
Searching for Extremely Blue UV Continuum Slopes at z = 7–11 in JWST/NIRCam Imaging: Implications for Stellar Metallicity and Ionizing Photon Escape in Early Galaxies

Published: December 2022

The ultraviolet (UV) continuum slope (β, where f

λ
∝ λ

β
) of galaxies is sensitive to a variety of properties, from the metallicity and age of the stellar population to dust attenuation throughout the galaxy. Considerable attention has focused on identifying reionization-era galaxies with very blue UV slopes (β < −3). Not only do such systems provide a signpost of low-metallicity stars, but they also identify galaxies likely to leak ionizing photons from their H ii regions as such blue UV slopes require the reddening effect of nebular continuum to be diminished. In this paper we present a search for reionization-era galaxies with very blue UV colors in recent JWST/NIRCam imaging of the Extended Groth Strip field. We characterize UV slopes for a large sample of z ≃ 7–11 galaxies, finding a median of β = −2.0. Two lower luminosity (M
UV ≃ −19.5) and lower stellar mass (6–10 × 107
M
⊙) systems exhibit extremely blue UV slopes (β = −2.9 to −3.1) and rest-optical photometry indicating weak nebular line emission. Each system is very compact (r

e
≲ 260 pc) with very high star formation-rate surface densities. We model the spectral energy distributions (SEDs) with a suite of BEAGLE models with varying levels of ionizing photon escape. The SEDs cannot be reproduced with our fiducial (f
esc,H II
= 0) or alpha-enhanced (Z
⋆ < Z
ISM) models. The combined blue UV slopes and weak nebular emission are best-fit by models with significant ionizing photon escape from H ii regions (f
esc,H II
= 0.5–0.8) and extremely low-metallicity massive stars (Z
⋆ = 0.01–0.06 Z
⊙). The discovery of these galaxies highlights the potential for JWST to identify large numbers of candidate Lyman continuum leaking galaxies in the reionization era and suggests low-metallicity stellar populations may be common in dwarf galaxies at z > 7.
Using the EPM method for the estimation of soil erosion in forest territories in the upper part of Dzherman River
Authors: Pavlova-Traykova Eli
Published: December 2022

One of the most vulnerable to soil erosion parts in Bulgaria is the Struma river watershed. In the past, a lot of erosion control activities have been carried out in this catchment, but the topographic condition and easily prone to soil erosion soils are still redounding to erosion processes. 

As a global problem with severe effects on the environment, soil erosion is on the agenda of scientific community. Because of difficult recognition on time, various methods for erosion risk and sediment loss assessment were applied. For mountainous watersheds one of the most appropriate approach is Erosion Potential Model (EPM). 

The study aims to evaluate soil erosion and investigate its spatial distribution by applying EPM, also known as Gavrilovic method. The object of investigation is the upper part of the Dzherman river, which is tributary of Struma river. The method was implemented only for forest territories to determine the most vulnerable part of the forest. The results showed that for the forest territories the average value of the coefficient Z is 0.19, which defines erosion as “low” and the average soil loss only for forest areas is 15.28 m3/km2/year. Nevertheless there are territories with more than 100 m3/km2/year. 
Microbial cellulose: an alternate source for plant cellulose

Published: December 2022

In the contemporary generation, rapid urbanization, industrialization, and declining woodland lead to global weather modifications. The massive scale of deforestation for firewood, constructions, paper products, textile, and plenty of different packages are steadily enforcing a critical poor impact on the surroundings. Inherently, plant cellulose has restrained utility because of the presence of hemicellulose and lignin. Consequently, studies in the discipline of microbial cellulose display many benefits over plant cellulose. It possesses numerous crucial and unique properties compared to plant cellulose, including high purity, better absorptivity, excellent polymerization, crystallization, in-situ mold potential, biodegradability, biocompatibility, and plenty of others. This assessment looks into a potent cellulose producer to develop an economically feasible manner for huge-scale production of microbial cellulose therefore, it may replace some of the requirements where plant cellulose has been currently in use.

Distribution of graminoids in open habitats in Tajikistan and Kyrgyzstan
Authors: Świerszcz Sebastian , Swacha Grzegorz , Raduła Małgorzata W. , Nowak Sylwia
Published: December 2022

Aims: Landscapes of Middle Asia are exposed to human influence due to long-lasting pastoral tradition, and now are largely dominated by non-forest vegetation. Graminoids perform key ecosystem functions, and constitute an important feed source for livestock. We studied the distribution patterns of graminoids cover under climatic and grazing pressure gradients in different open vegetation types. Study area: Tajikistan, Kyrgyzstan. Methods: 1,525 vegetation plots representing five open vegetation types (mires, salt marshes, tall-forb communities, pseudosteppes and steppes) were extracted from the Vegetation of Middle Asia Database. We assessed the relative cover of graminoid species in each vegetation type. The importance of mean annual temperature, sum of annual precipitation, aridity and livestock density as drivers of relative cover of graminoids contribution patterns in the five vegetation types were explored with use of polynomial functions and commonality analysis. Results: Open ecosystems of Middle Asia are characterized by different graminoid contributions. The highest relative cover of graminoids was found for steppes, pseudosteppes and mires. Comparison of model fits for relationship between the graminoids cover, climatic parameters and livestock pressure indicated advantage of polynomial models. The best-fitting models for pseudosteppes were for mean annual temperature, Aridity Index and livestock density, for steppes mean annual temperature and Aridity Index, and for salt marshes mean annual temperature. For mires and tall-forb communities, the models showed a poor fit or no effect of the variables studied. Conclusions: Our study shows that climate and livestock pressure have an impact on the contribution of graminoids in open vegetation types, but a general pattern is difficult to describe. Ongoing climate change may influence the share of graminoids in salt marshes, steppes and pseudosteppes. Grazing (with a common effect of climatic factors) is the most important factor influencing graminoids contribution on pseudosteppes, confirming the secondary origin of this vegetation type.

Published: December 2022

The development of urban digital inclusive finance has a complex network connection, and the characteristics of this network affect urban innovation and entrepreneurship. By using 287 cities from 2015 to 2019 in China, this paper constructs the network of Chinese digital inclusive finance, extracting two typical network characteristics. And it further studies the impact of the two network characteristics on innovation and entrepreneurship in various cities. The empirical results show that: first, the network centrality characteristics of digital inclusive finance have a significant promoting effect on urban innovation and entrepreneurship; second, the impact of the network centrality characteristics of digital inclusive finance is related to the speed of industrial structure transformation, but the impact mechanism is related to the node number instead of the node strength; third, the impact of the network centrality characteristics on innovation and entrepreneurship exists heterogeneity among cities and the moderately developed cities have the largest impact.

Cet article a pour objectif d’analyser l’usage
fait par Miguel Reale de la pensée de Carl Schmitt en vue de légitimer
juridiquement le coup d’État civil-militaire au Brésil en 1964. Nous
soutenons que la pensée politique de Reale a évolué du corporatisme
fasciste pendant sa jeunesse, vers une pensée toujours autoritaire,
mais dorénavant épurée de ses références fascistes et désormais fondée
sur un outillage conceptuel philosophique et juridique sophistiqué,
dans lequel les concepts schmittiens occupent une place centrale. Pour
examiner l’usage de Schmitt par Reale, nous nous pencherons sur
l’œuvre de l’un et de l’autre : du premier, Théologie politique (1922), La notion de politique (1927)
et Le gardien de la
Constitution (1928) ; du second, ses mémoires Destinos Cruzados et A Balança e a Espada (1987) et Imperativos da revolução de
março (1964). Cet article est divisé en trois parties. Dans la
première, nous examinons quelques présupposés théoriques et
méthodologiques sur lesquels nous nous sommes appuyés pour mener à
bien nos analyses ; dans la seconde, nous nous concentrons sur les
travaux de Carl Schmitt, mettant en exergue les principaux concepts
que Miguel Reale s’est appropriés ; dans la troisième, enfin, nous
analysons comment Reale les a opérationnalisés pour expliquer et,
surtout, légitimer la prise de pouvoir militaire en 1964.

Published: December 2022

O presente artigo buscou analisar o Grupo de incentivo ao Aleitamento Materno de Criciúma-SC, que funcionou de 1987 a 1990. Esse grupo coordenado por um médico homem, era formado também por participantes voluntários/as e pessoas ligadas à área da saúde. O GIAM era voltado as mulheres mães e operava formas da pedagogia materna direcionadas a proteger a infância e em suma, ensinar, educar e promover assistência às mulheres mães. Utilizava-se de materiais educativos como cartilhas, panfletos, palestras, cursos e materiais pedagógicos para promover a defesa do aleitamento materno e em contrapartida, pontuar todos os malefícios das mães não amamentarem seus filhos. O Grupo também demonstrava interesse em adentrar no Conselho Municipal de Saúde de Criciúma, atuando na agenda das políticas públicas para mulheres. O GIAM em suas práticas de pedagogia materna traçou o que era considerado uma maternidade ideal que ao mesmo tempo em que tentava proteger a infância, também regulava as condutas das mulheres dentro das famílias.

Authors: Wimalasuriya I. G. R. N. , Kapukotuwa A.
Published: December 2022

‘On-site interpretation’ is a critical success factor in conveying the significance and multiple heritage values of a cultural heritage site to the visitors. The initial assessment done on the current status of the on-site interpretation at six Cultural World Heritage Sites (CWHS) in Sri Lanka under this study, unveiled the need for a ‘Value-based interpretation strategy’ and integration of ‘appropriate’ digital interpretation techniques with the existing techniques. Accordingly, the objective of this study was to explore the potential digital interpretation techniques and their applicability, aiming at enhancing the level of on-site interpretation of Sri Lankan CWHS. The data gathered through thirteen in-depth interviews with respective professionals, on-site observations, a literature survey, and a survey questionnaire of 505 respondents, were analyzed against 24 criteria, categorized under six themes (Site condition, Legal and Regulatory concerns, Technical and Financial feasibility, Content preparation, Implementation, and Sustainability), which were developed as the theoretical framework for the present study by referring the literature. It was determined that ‘Augmented Reality (AR) enabled Mobile apps’, a combination of Mobile apps and Mobile-AR technology, are feasible and appropriate for all six CWHS. This study recommends a dedicated app for each CWHS, enriched with Mobile-AR modules (virtual tour guide, virtual markers for visitor navigation, virtual reconstructions, AR filters), Comparisons to world context, Customizable itineraries, Side-tabs of heritage values, User engagement features, etc., to provide a tailor-made and innovative visitor experience in complying with the value-based interpretation strategy. In addition, the study presents a set of recommendations for the proposed apps under the themes of ‘Content creation’, ‘Organizational adaptability’, ‘Policy changes’, ‘Partnerships and Promotion’, and ‘Post-Implementation Evaluation and Extended Uses’ for a successful future implementation. The composite outcome of the present study could be followed as a reference model in enhancing the level of on-site interpretation at the CWHS of the country but not limited to.

Nature and extent of degradation and deterioration of Medavela Rajamaha Vihara Palm Leaf Manuscript Collection
Authors: Dehigama Kanchana , Neththasinghe N. M. P.
Published: December 2022

Palm Leaf Manuscripts faced the threat of deliberate as well as unintentional destruction since ancient times. Custodian individuals and personnel protected the collections from natural and manmade disasters by adhering to the traditional conservation and preservation methods that prevailed for generations. However, the advent of printing, absence of patronage, lack of know-how, less priority paid, and attitudinal changes led Palm Leaf Manuscript collections to deteriorate fast, especially after the beginning of colonial administration. Hence, this study is carried out to identify the condition of the Palm Leaf Manuscript available at the Medavela Rajamaha Vihara based on the nature and extent of the degradation and deterioration. To investigate the collection of qualitative data collection techniques such as survey method and observations was employed to draw data. Palm Leaves as a natural organic material, has been deteriorated owing to several factors. Chemical, physical, and biological degradation, caused by improper storage, incorrect climatic conditions, inappropriate handling, and damage instigated by pests are among the many circumstances that caused the condition of these manuscripts. Safeguarding the collection is suggested by adhering to both modern and traditional techniques. Future research avenues are open for documentation, conservation, and preservation of the collection.
An Investigative Study of Trade relations between Sri Lanka and South India mentioned in Tamil inscriptions of Sri Lanka
Authors: Nanayakkara Kaveesha
Published: December 2022

According to Tamil inscriptions in Sri Lanka, we can get to know some information on trade relations between Sri Lanka and South India. In this study, the information on the trade relations between Sri Lanka and South India in the Tamil inscriptions found in Sri Lanka is studied investigative. This study was conducted under the research problem of, what information is contained in Sri Lankan Tamil inscriptions about the trade relationship between Sri Lanka and South India. And this aimed to obtain information on the economic connection between Sri Lanka and South India through Tamil inscriptions found in Sri Lanka. This whole research depends on the readings of Tamil inscriptions found in Sri Lanka. Hence, this could be categorized as desktop research and conducted as qualitative research. To collect data, I used library and museum studies under the secondary data collection method and later analyzed them. In this study, I got data from Tamil inscriptions found in the Anuradhapura, Kalutara, and Kurunegala districts and, the Sinhala inscription of Queen Lilawathi. Those inscriptions mention some South Indian trade corporations, that have been involved in foreign trade in Sri Lanka such as Ainnurruvar, and Nanadeshi. Weerakoti and Nanadeshi, which can be trusted as Ainnurruvar trade corporation and its affiliates, also appear to have been involved in foreign trade. The inscriptions state that the trading companies built and sponsored Buddhist and Hindu temples in the country. There were trade cities in Sri Lanka that were associated with trade corporations in Real-time and also tax collection was associated with those corporations. It can be concluded that during the Polonnaruwa period, South Indian trade corporations were active in Sri Lanka and Sri Lanka remained an economic hub.

Published: December 2022

Presently, lots of countries have initiated sustainable approaches to destination development. As result, cycling is also promoted due to the enormous environmental benefits it offers to ensure a smokeless tourism industry. Accordingly, this study aims to identify the potential and challenges of cycling tourism as a sustainable mode of transport for destination promotion. Further, the study explores the challenges of promoting cycling along with the tourists' perception. Ella-Sri Lanka was chosen as the main study location, and for in-depth analysis, the scenario study employed a qualitative approach. Purposive sampling and semi-structured interview techniques were applied for the data collection and at the data saturation point, 20 cycling tourists' responses were recorded for data analysis. The thematic analysis method was used for data analysis. Findings associated with the benefits of cycling were divided into four main themes economic, social-cultural, environmental and health, and other benefits. Additionally, tourist perception and the related challenges were categorized under three themes namely, safety and security-related issues, product, and process-related issues, and infrastructure facilities. Finally, implications for developing a more participatory policy approach towards sustainable destination development are highlighted considering the cycle renters, tourist guides, travel agents, accommodation providers, tourist services and facility providers, local authorities, government, and other relevant stakeholder groups involved in the tourism sector.

Published: December 2022

Sensors are key elements for capturing environmental properties and are today indispensable in the industry for monitoring and control of industrial processes. Many applications are demanding for highly integrated intelligent sensors to meet the requirements on safety, clean, and energy-efficient operation, or to gain process information in the context of industry 4.0. While in many everyday objects highly integrated sensor systems are already state of the art, the situation in an industrial environment is clearly different. Frequently, the use of sensor systems is impossible due to the fact that the extreme ambient conditions of industrial processes like high operating temperatures or strong mechanical loads do not allow a reliable operation of sensitive electronic components. Eight Fraunhofer Institutes have bundled their competencies and have run the Fraunhofer Lighthouse Project “eHarsh” to overcome this situation. The project goal was to realize sensor systems for extremely harsh environments, whereby sensor systems are more than pure sensors, rather these are containing one or multiple sensing elements and integrated readout electronics. Various technologies, which are necessary for the realization of such sensor systems, have been identified, developed, and finally bundled in a technology platform. These technologies are, e.g., MEMS and ceramic-based sensors, SOI-CMOS-based integrated electronics, board assembly and laser-based joining technologies. All these developments have been accompanied by comprehensive tests, material characterization, and reliability simulations. Based on the platform, a pressure sensor for turbine applications has been realized to prove the performance of the eHarsh technology platform.

Spontaneous dissection of the celiac trunk is a rare and uncommon cause of acute abdominal pain. Risk factors, natural history and optimal treatment are still unclear due to the rarity of the disorder. Therapeutic strategies and follow-up procedures are based on limited observations, and the absence of guidelines warrants a patient-tailored approach. We report the case of a 50-year-old woman who presented to our emergency department for epigastric pain, nausea, and vomiting resulting from a spontaneous dissection of the celiac trunk, successfully treated endovascular technique.

Pancreatic panniculitis is a rare disease characterized by subcutaneous fat necrosis. It could be the result of an associated pancreatic tumor. Herein, we reported a 63-year-old man who presented with progressive bilateral lower limb edema accompanied with nodule-like lesions for 1 month. His serum lipase was 3,927 U/L (normal, 0–160 U/L). Histopathology of the skin specimen revealed lobular panniculitis, favoring a diagnosis of pancreatic panniculitis. Abdominal computed tomography (CT) scan with contrast showed a huge mass in his left upper quadrant. Endoscopic ultrasound showed a mixed echoic tumor, measuring 11.9 × 7.8 cm in dimensions, originating from the pancreatic tail. Biopsy performed via an endoscopic ultrasound showed a poorly differentiated acinar cell carcinoma. Because of the unresectable status of the tumor, the patient underwent chemotherapy with paclitaxel and gemcitabine. After chemotherapy, his skin lesions improved progressively. It is important to treat pancreatic panniculitis with its underlying pancreatic disease.

Assessment of radiological impact and for planning and preparedness programs, monthly atmospheric dispersion patterns at Kalpakkam have been studied using observed surface meteorological data during 2015–2020. The influence of meteorological factors such as wind speed, wind directions, percent of calm, atmospheric stability, and rainfall on dispersion patterns has been evaluated. The higher wind speed range (>4 m/s) is observed from 11:00 h to 19:00 h with an average wind speed of 4.17 m/s and the highest value observed in the month of May. Extremely stable F category and percent of calm observed to be lowest in the month of June. This study reveals that the high concentration area is toward seaside sectors during the southwest monsoon season from June to September and the remaining months, January to May and October to December, the most probable dispersion toward southwest, South, and North covering land sectors. Wet deposition due to maximum rainfall and more rainy days in the month of November during the northeast monsoon. The study provides site-specific information on dispersion patterns, an essential tool and crucial support for risk management with respect to radiological impact, monitoring and assessment in normal and emergency scenarios of a nuclear facility, and guiding resources for siting and design of the new facility in and around Kalpakkam.
Formation control of multiple unmanned vehicles based on graph theory: A Comprehensive Review

Published: December 2022

In recent years, formation control for multiple unmanned vehicles becomes an active research topic that has received a lot of attention from scientists due to its superior advantages compared with other conventional systems. Algebraic graph and graph rigidity theories are the two main mathematical backgrounds of the formation control theory. The graph theory is used to describe the interconnections among vehicles in formation while rigid graph theory - an important subset of graph theory - ensured that the inter-vehicle distance constraints of the desired formation are enforced via the graph rigidity. This paper provides a comprehensive review of graph theory supporting formation control for groups of unmanned aerial vehicles (UAV) or swarm UAVs. The background of the theory and the recent developments of graph-theory-based formation control are reviewed. We provide a cohesive overview of the formation control and coordination of multiple vehicles. Finally, some challenges and future potential directions in formation control are discussed.
Potential Imaging Biomarkers of Cognitive Frailty
Authors: Park Jaesub , Kim Woo Jung
Published: December 2022

Cognitive frailty (CF) is a state of impairment in both cognitive and motor functions. The concept of CF has been developed in several ways. However, it is difficult to identify consistent neuroimaging findings according to the application of the operational definition of different frailty models within the same concept, as well as the diversity of the concept itself of CF. This study aimed to review neuroimaging studies of CF and to determine suitable imaging biomarkers of CF. White matter abnormalities (e.g., white matter hyperintensity and microbleeds) seem likely to be considered imaging biomarkers of CF. The volume of the cerebral/cerebellar cortex and that of the subcortical nuclei are also candidates of imaging biomarkers of CF. These imaging biomarkers are expected to be more useful in discriminating the need for screening CF in visitors of clinics or health examination centers than in detecting the presence of CF in community-dwelling older adults.
Sustainable Business Model Innovation: From Value Uncaptured to Value Opportunities
Authors: Gennari Francesca
Published: December 2022

COVID-19 pandemic crisis threatened the stability of economy and the survival of many firms, but it has been also the chance to challenge the current economic development path and to rethink firms’ business models according to a more sustainable approach. Academic literature states that business model (BM)  innovation is a driver for the transition to sustainability. Sustainable business models (SBMs) incorporate sustainability vision in the main components of business model, which are value proposition, value creation and value capturing. Nevertheless, the usual approach to business models, based on a positive concept of value, can underestimate some areas of potential opportunities to catch. For this reason, in this paper we suggest to adopt a novelty approach that emphasizes the negative concept of value (value uncaptured) to identify unexploited value opportunities. This approach can help firms innovating their BMs towards SBMs.

Published: December 2022

Objectives:In this study, we aimed to compare the efficacy of ultrasonography (US) and steroid phonophoresis (PH) treatments in patients with idiopathic carpal tunnel syndrome (CTS).

Patients and methods:Between January 2013 and May 2015, a total of 46 hands of 27 patients (5 males, 22 females; mean age: 47.3+13.7 years; range, 23 to 67 years) with idiopathic mild/moderate CTS without tenor atrophy or spontaneous activity in abductor pollicis brevis were included. The patients were randomly divided into three groups. The first group was ultrasound (US) group, the second group was PH group, and the third group was placebo US group. Continuous US with a frequency of 1 MHz, an intensity of 1.0 W/cm2was used in the US and the PH groups. The PH group received 0.1% dexamethasone. Placebo group received a frequency of 0 MHz, an intensity of 0 W/cm2US. Treatments were administered for five days a week, a total of 10 sessions. All patients also wore night splints during treatment. The Visual Analog Scale (VAS), Boston Carpal Tunnel Questionnaire consisting of two parts, namely the Symptom Severity Scale and Functional Status Scale), grip strength, and electroneurophysiological evaluations were compared before the treatment, after the treatment, and three months later.

Results:All clinical parameters improved in all groups after treatment and at three months, except for the grip strength. Recovery in the sensory nerve conduction velocity between palm and wrist was seen in US group at three months after the treatment; however, recovery in the sensory nerve distal latency between the second finger and palm was seen in PH and placebo groups after treatment and at three months after the treatment.

Conclusion:The results of this study suggest that splinting therapy combined with steroid PH, placebo or continuous US is effective for both clinical and electroneurophysiological improvement; however, electroneurophysiological improvement is limited.

Objectives: Asians represent the fastest growing ethnic group in the United States. Despite significant diversity within the group, many transplant studies treat Asians as a homogeneous entity. We compared patient and graft survival among major Asian eth- nicities to determine whether any subgroup has superior out- comes. Methods: We conducted a retrospective analysis of kidney trans- plants on Asian and White patients between 2001 and 2012. Co- variates included gender, age, comorbidities, and donor category. Primary outcomes included one-year patient and graft survival. Secondary outcomes included delayed graft function (DGF) and rejection as cause of graft loss and death. Results: Ninety-one Asian patients were identified. Due to the large proportion of Chinese patients (n=37), we grouped other Asians into one entity (n=54) for statistical comparison among Chinese, other Asians, and Whites (n=346). Chinese subjects had significantly lower body mass index (BMI) (p=0.001) and had the lowest proportion of living donors (p>0.001). Patient survival was highest in our Chinese cohort (p>0.001)Discussion: Our study confirms outcome differences among Asian subgroups in kidney transplantation. Chinese demonstrate better patient survival at one year than Whites and non-Chinese Asians despite fewer live donors. Lower BMI scores may partly explain this. Larger, long-term studies are needed to elucidate outcome disparities among Asian subgroups
