Interannual variability of sea level in the southern Indian Ocean: local vs. remote forcing mechanisms
Authors: Kersalé Marion , Volkov Denis L. , Pujiana Kandaga , Zhang Hong
Published: February 2022

Abstract. The subtropical southern Indian Ocean (SIO) has been described as one
of the world's largest heat accumulators due to its remarkable warming
during the past 2 decades. However, the relative contributions of
remote (of Pacific origin) forcing and local wind forcing to the variability
of heat content and sea level in the SIO have not been fully attributed.
Here, we combine a general circulation model, an analytic linear reduced-gravity model, and observations to disentangle the spatial and temporal
inputs of each forcing component on interannual to decadal timescales. A
sensitivity experiment is conducted with artificially closed Indonesian
straits to physically isolate the Indian Ocean and Pacific Ocean,
intentionally removing the Indonesian Throughflow (ITF) influence on the
Indian Ocean heat content and sea level variability. We show that the
relative contribution of the signals originating in the equatorial Pacific
vs. signals caused by local wind forcing to the interannual variability
of sea level and heat content in the SIO is dependent on location within the
basin (low latitude vs. midlatitude and western side vs. eastern side of the basin). The
closure of the ITF in the numerical experiment reduces the amplitude of
interannual-to-decadal sea level changes compared to the simulation with a
realistic ITF. However, the spatial and temporal evolution of sea level
patterns in the two simulations remain similar and correlated with El
Niño–Southern Oscillation (ENSO). This suggests that these patterns are
mostly determined by local wind forcing and oceanic processes, linked to
ENSO via the “atmospheric bridge” effect. We conclude that local wind
forcing is an important driver for the interannual changes of sea level,
heat content, and meridional transports in the SIO subtropical gyre, while
oceanic signals originating in the Pacific amplify locally forced signals.
Snow properties at the forest tundra ecotone: predominance of water vapor fluxes even in thick moderately cold snowpacks
Authors: Lackner Georg , Domine Florent , Nadeau Daniel F. , Lafaysse Matthieu , Dumont Marie
Published: February 2022

Abstract. The forest-tundra ecotone is a large circumpolar transition zone between the Arctic tundra and the boreal forest, where snow properties are spatially variable due to changing vegetation. The extent of this biome through all circumpolar regions influences the climate. In the forest-tundra ecotone near Umiujaq in northeastern Canada (56°33'N, 76°28'W), we contrast the snow properties between two sites, TUNDRA (located in a low-shrub tundra) and FOREST (located in a boreal forest), situated less than 1 km apart. Furthermore, we evaluate the capability of the snow model Crocus, initially developed for alpine snow, to simulate the snow in this subarctic setting. Snow height and density differed considerably between the two sites. At FOREST, snow was about twice as deep as at TUNDRA. The density of snow at FOREST decreased slightly from the ground to the snow surface, in a pattern that is somewhat similar to alpine snow. The opposite was observed at TUNDRA, where the pattern of snow density was typical of the Arctic. Crocus was not able to reproduce the density profiles at either site using its standard configuration. We therefore implemented some modifications for the density of fresh snow, the effect of vegetation on compaction and the lateral transport of snow by wind. We demonstrate that upward water vapor transport is the dominant mechanism that shapes the density profile at TUNDRA, while a contribution of compaction due to overburden weight becomes visible at FOREST. The adjustments that were made to Crocus partly compensate for the lack of water vapor transport in the model, but are site-specific to some extent. Furthermore, the challenges using Crocus suggest that the general lack of water vapor transport in the snow routines used in climate models leads to an inadequate representation of even thick and moderately cold snowpacks, with possible major impacts on meteorological and climate projections.

We report our experience in patients who were treated with cold plasma wound therapy from 2016 to 2020. Thirty-six patients with a median age of 71 years (23 males, 13 females) were registered in a prospective database. The median follow up was six months. In 15 patients, their wounds were associated with peripheral arterial disease, and they received peripheral interventional or open revascularisation prior to cold plasma therapy. Seven patients had a chronic venous insufficiency and 3 diabetic patients had chronic wounds caused by polyneuropathy. One patient suffered from chronic lymphoid disease. The cause of the wound could not be identified in the remaining patients. Wound treatment was conducted in an outpatient setting, if possible. Four patients were lost during follow-up. Surgical debridement of the wound before cold plasma therapy began was necessary in 14 cases. Each patient received 1 to 3 cold plasma treatments a week; 2 patients were treated for 1 year and the remaining patients were treated for 4 to 11 weeks. There were no major amputations in the long-term follow-up. In 25 patients, the progress of the wound stopped and in 11 patients the wounds were closed at the end of the therapy. In conclusion, our results support the use of cold plasma in complex wounds. Causal therapy is mandatory. Further studies are necessary to evaluate the impact of supplemental modern wound treatment with cold plasma therapy.

Published: February 2022

Objective: This study aims to compare the effectiveness of hyperkalemia drug combinations in reducing potassium levels in chronic kidney disease (CKD) patients. Methods: This is an observational study on medical records of CKD patients with hyperkalemia at Dr. Saiful Anwar and Lavalette Hospitals, Malang, Indonesia. From 2017 to 2019, 78 hyperkalemia correction data were obtained from 47 patients’ medical records. The hypothesis test used in this study was the one-way ANOVA test. Results: Drug combinations of calcium gluconate, Actrapid® HM, and D40% (∆p = 0.62 mmol/L); calcium gluconate, Actrapid® HM, D40%, and Ventolin® Nebules (∆p = 0.72 mmol/L); and calcium gluconate, NovoRapid®, and D40%® (∆p = 1.03 mmol/L) were able to significantly reduce serum potassium levels (p < 0.05). A drug combination of calcium gluconate, Humulin® R, and D40% (∆p = 0.84 mmol/L) was also able to reduce serum potassium levels but not statistically significant (p > 0.05). The comparison test results of the four groups of drug combinations showed that no combination of drugs was superior to others in lowering potassium levels (p > 0.05). Conclusions: The four groups of hyperkalemia drug combinations can reduce the patient’s serum potassium level and have the same effectiveness.

Published: February 2022

In modern medication, drug-loaded novel polymeric nanoparticles have potential advantages over conventional dosage forms. The present study focused on the formulation development and evaluation of newly introduced angiotensin receptor blocker (ARB) eprosartan mesylate loaded biodegradable acid terminated poly(lactide-co-glycolide) (50:50) nanoparticle using double emulsion solvent evaporation technique. This methodology was found to improve the therapeutic efficacy as Eprosartan Mesylate belongs to BCS class-II and water-insoluble antihypertensive drug with 13% bioavailability. In the earlier stage, screening was performed to find out the suitable combination of excipients (Polyvinyl alcohol, Dichloromethane and Ethanol) to formulate the nanoparticles. In this present study, the physical and chemical properties of polymer and drug were determined before and after the formulation of nanoparticles using experimental techniques, such as Differential Light Scattering (DLS), zeta potential, X-ray Deffractometry (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Liquid Chromatography-Mass Spectrometry (LC-MS/MS) analysis. The eprosartan mesylate loaded PLGA nanoparticles showed fairly monodispersive, as determined from DLS (average particle diameter 136 nm, Poly Dispesity Index = 0.3). The zeta potential was found to be -10.8mV. This formulation showed a prolonged improved drug release (82.03%) for 360 hours in phosphate buffer (pH7.4) as compared to the conventional marketed dosage form. In-vitro release kinetics data of NPs (R2=0.8979) and diffusion exponent values (n=0.3328) suggested that optimized followed the Korsmeyer-Peppas model with Fickian mechanism.

Published: February 2022

People in Bangladeshi village area have long practice to take plant-based products for their basic health care. Schleichera oleosa (Lour.) Oken (Family: Sapindaceae) is an important folk medicine in Bangladesh, India that has been used to cure a wide variety of human ailments. Here, the crude methanol extract of S. oleosa leaf (MESOL) and its various solvent (Hexane, dichloromethane, ethyl acetate, aqueous) fractions were evaluated to determine the level of biological activities by both In vitro and in vivo approaches. The crude methanol extract along with its different solvent fractions was investigated for antioxidant activity by measuring total phenolic content and DPPH radical scavenging assay. Cytotoxic activity was performed by brine shrimp lethality bioassay method. The blood clot lysis ability was screened using aspirin as standard. In vitro anti-inflammatory test was performed by RBC membrane stabilizing activity. Beside In vitro analysis, tail immersion procedure and formalin-induced writhing test were carried out to evaluate the analgesic activity of the plant extract in mice. In addition, the anti-diarrheal activity was determined by castor oil-induced diarrheal model in mice. The ethyl acetate fraction of S. oleosa showed prominent antioxidant activity by scavenging DPPH radical with an IC50 value of 9.46 μg/ml, possibly due to its highest phenol content (103.23 mg of GAE/g of plant extract). The crude methanol extract revealed significant cytotoxicity towards brine shrimp with an LC50 value of 16.79 μg/ml. The dichloromethane fraction showed moderate blood clot lysis ability (28.93% clot lysis) while the crude methanol extract of S. oleosa leaf produced the highest 74.62% inhibition of hemolysis that was induced by hypotonic solution. During in vivo assay, the crude methanol extract of S. oleosa leaf produced significant (p<0.05) and dose-dependent pain response and anti-diarrheal effect in mice. The present study revealed that Schleichera oleosa possesses significant pharmacological activities. However, additional studies are compulsory to discover the mechanism of action of this plant extract.

Published: February 2022

Peptic ulcers are best treated by proton pump inhibitors (PPIs), however, other simple gastrointestinal (GIT) disorders should be better treated by other acid neutralizing or anti-secretory agents. Unfortunately, most GIT diseases were reported to be treated by PPIs even though non-indicated cases. The reasons might include ease availability with/without prescription, reduce patient awareness, and overprescription of PPIs by the health care professionals. This study aims to highlight the effect of these drugs on the renal function test. Patients were recruited and enrolled in the study from outpatients private clinics and plasma samples were withdrawn from control healthy, esomeprazole and omeprazole users individuals. Plasma samples were frozen for further analysis, creatinine and urea test were conducted on overall samples and the results were displayed confirming significant dysfunctioning of the renal system from PPIs use. The study concluded that creatinine and urea are higher in a patient on esomeprazole than omeprazole and the control group. The study recommends general awareness of the society about regular use of these medications unless otherwise carefully required.

Exponential decay for a strain gradient porous thermoelasticity with second sound
Authors: Ahmima Afaf , Fareh Abdelfeteh
Published: February 2022

In this paper, we consider a strain gradient porous elastic bar subjected to a thermal disturbance modelled by Cattaneo's law for heat conduction. We use the semigroup approach to prove the existence of a unique weak solution. Although the thermal dissipation induced by the second sound thermoelasticity is weaker than that caused by the classical heat conduction, we prove that the solution decays exponentially.
Verifying global stability of fluid flows despite transient growth of energy
Authors: Goluskin David
Published: February 2022

Verifying nonlinear stability of a laminar fluid flow against all perturbations is a classic challenge in fluid dynamics. All past results rely on monotonic decrease of a perturbation energy or a similar quadratic generalized energy. This "energy method" cannot show global stability of a flow in which perturbation energy may grow transiently. For the many flows that allow transient energy growth but seem to be globally stable (e.g. pipe flow and other parallel shear flows at certain Reynolds numbers) there has been no way to mathematically verify global stability. After explaining why the energy method was the only way to verify global stability of fluid flows for over 100 years, I will describe a different approach that is broadly applicable but more technical. This approach, proposed in 2012 by Goulart and Chernyshenko, uses sum-of-squares polynomials to computationally construct non-quadratic Lyapunov functions that decrease monotonically for all flow perturbations. I will present a computational implementation of this approach for the example of 2D plane Couette flow, where we have verified global stability at Reynolds numbers above the energy stability threshold. This energy stability result for 2D Couette flow had not been improved upon since being found by Orr in 1907. The results I will present are the first verification of global stability – for any fluid flow – that surpasses the energy method. This is joint work with Federico Fuentes (Universidad Católica de Chile) and Sergei Chernyshenko (Imperial College London).

Anaphylaxis is a severe, potentially life-threatening systemic hypersensitivity reaction. Despite the global incidence shows an increasing trend for anaphylaxis, few cases appear to be promptly recognized and correctly managed, showing a significant underuse of epinephrine injections. The most recent state of the art highlights the need for unanimously accepted diagnostic criteria and the essential role of intramuscular epinephrine as the only first-line treatment when a patient is experiencing an acute anaphylactic reaction. On the other hand, evidence emphasize that glucocorticoids have a limited role in the acute management of anaphylaxis and support the use of antihistamines with the only aim to relieve cutaneous symptoms. This review aims to present the latest guidelines concerning management and therapeutic approach to anaphylaxis in the Emergency Department, with a practical slant, underlying the utmost importance of epinephrine administration both in a domestic and hospital setting.
Farmaci e allattamento: ancora un dilemma?
Authors: Colaceci Sofia , Zambri Francesca , Reali Laura , Giusti Angela
Published: February 2022

It is widely believed that many medications are dangerous for infants if taken by nursing mothers. So, they often choose to give up the drug in order to continue breastfeeding or, conversely, to discontinue breastfeeding to take the medication. This occurs even for medications considered as compatible by scientific evidence. The lack of coherent official information on the use of medications during lactation is probably one of the main reasons inducing an excess of prudence, based on presumption of risk rather than on evidence. In addition, literature suggests that breastfeeding training has a crucial role to increase healthcare professionals’ knowledge, attitudes and practices and to improve professional support for breastfeeding, even in case of maternal use of medications or natural products.

Authors: Gomes Mayara Karoline Freire , Lima João Lucas Tavares de , Santana José Almir
Published: February 2022

Introdução: O vírus da imunodeficiência humana foi descoberto no Brasil no ano de 1982. O causador da doença crônica mais conhecida como aids, em que a pessoa vivendo com vírus da imunodeficiência humana/aids tem seu sistema imunológico comprometido, pois as principais células atacadas são os linfócitos T CD4. Objetivo: O objetivo deste trabalho é mostrar que a infecção pelo vírus da imunodeficiência humana ainda persiste e que as crianças que nascem de mães infectadas também podem nascer com carga viral, sendo diagnosticadas após o primeiro mês de vida. A meta é erradicar a transmissão vertical do vírus da imunodeficiência humana e fazer com que a criança não desenvolva aids em seus primeiros anos de vida. Métodos: O estudo foi uma pesquisa de campo em que foram extraídos dados do Sistema de Informação de Agravos e Notificações, sistema utilizado em todo território brasileiro e em experiência na área de vigilância epidemiológica como referência técnica da vigilância do vírus da imunodeficiência humana/aids da Secretaria Estadual de Saúde. Resultados: De 2016 a 2020 foram notificadas 516 gestantes vírus da imunodeficiência humana, 477 crianças expostas e 6 crianças no agravo aids no Sistema de Informação de Agravos de Notificação; entre essas, 3 foram diagnosticadas com vírus da imunodeficiência humana e 3 já com a aids, sendo todas infectadas por transmissão vertical, seja por via cordão umbilical, seja por amamentação, que também é proibida nesses casos. Conclusão: Diante do que foi exposto é importante que os serviços de saúde abranjam e ofereçam uma assistência voltada para saúde da mulher de forma integral, seja em idade fértil, seja gestante. O diagnóstico do vírus da imunodeficiência humana é algo ainda temido por muitos, mas o que precisa ser informado à população é que existe tratamento e é gratuito, para que não ocorra a transmissão vertical para essas crianças e também a infecção entre parceiros.
International Real Estate Review

One of the most important issues in emerging markets is the timing and intensity of land development decisions and how these decisions affect property values. In these markets, newly developed office space and residential units often account for a substantial proportion of the aggregate supply of similar types of developed properties. In this article I use a real option model to study the land development problem faced by a central planner. The optimal capital intensity, the value of land and the post- development rents and property values in these markets are strikingly lower than the corresponding values in the markets where the demand is perfectly elastic. Furthermore, the optimal capital intensity and the value of land are most sensitive to the market demand conditions in the emerging markets experiencing the fastest growth or greatest uncertainty, or at times when interest rates or construction costs are lowest.

Buying a house usually satisfies housing consumption demand and housing investment demand, simultaneously. In order to disentangle the above two types of demand, households, in this study, are separated into three subtenure groups i.e. renters, owners owning one house, and owners buying a second or more houses. Presumably, renting a house is for consumption only, while buying a second house is usually for investment purposes. Applying a two-period model and two data sets from DGBAS and from Land Bank of Taiwan, the estimated results are as follows: Firstly, the income elasticity of pure consumption demand for housing is very close to unity (1.0413). Secondly, the income elasticity for a pure investment demand is greater than one (1.2643). Finally, for a household owning only one house, the shares for consumption motive and for investment motive are 26% and 74%, respectively.

This paper offers an explanation for the existence of price control on new houses in Korea, which is deemed both inefficient and inequitable. This phenomenon cannot be explained by the conventional model of rent seeking or the capture theory of regulation. Instead, it is attributable to the popular belief that the removal of the price regulation will lead to the increase in the overall housing price by increasing the demand for existing houses that are a perfect substitute for new houses. However, the paper, using a stock-adjustment model of the housing market, demonstrates that the claimed outcome cannot materialize under perfect foresight or adaptive expectation. The outcome is possible in the short run under a peculiar expectation scheme of a self-fulfilling nature. But even in this case, the price increase will be a one-time event and in the long-run overall housing prices will fall below the level that would prevail if the price regulations were maintained.

The Hong Kong residential market is unique in several aspects: restricted land supply, high price volatility, high appreciation rate, a small group of large developers, and a huge public housing sector. Assuming that higher price appreciation and volatility can be attributed to the limited land supply, this study examines the relationships among developers’ housing-supply decisions, government land-supply decisions, and public housing policies. Using data for the 1973-1997 period, our result shows that an increase in land supply by the Hong Kong government may not be a solution to the perceived shortage of housing supply in Hong Kong. This finding indicates that it is important to examine developers’ profit maximization strategies when enacting public policies related to property markets.

Foreign real estate investment funds have recently been added to the practical investment opportunity sets of ordinary Japanese investors. This paper analyzes the additional diversification benefits of U.S. REITs and Australian listed property trusts (LPTs) for Japanese investors who already hold Japanese, U.S., and Australian financial assets while considering different risk definitions in a mean-lower partial moment (MLPM) framework. The study uses data from August 1994 to July 2004. The impacts of currency adjustment and risk definition on the diversification benefits are examined. Our results suggest that the additional diversification benefits of U.S. REITs and Australian LPTs can be obtained only in very limited cases by Japanese investors.

O apego materno fetal caracteriza-se pela intensidade com a qual a gestante manifesta sentimentos e cuidados pelo bebê. O estudo investigou os níveis de apego materno-fetal, ansiedade e depressão em gestantes de alto risco. Trata-se de pesquisa quantitativa, descritiva, realizada com 37 gestantes de alto risco em acompanhamento pré-natal, em Hospital Universitário da região metropolitana de Porto Alegre/RS. Foram coletadas informações da ficha sociodemográfica, Escala de Apego Materno-Fetal e dos Inventários Beck de Depressão (BDI) e Ansiedade (BAI). Os resultados indicaram (97,3%) de apego máximo e (2,7%) de apego médio, dentre as mulheres. Quanto à classificação do BAI e BDI, a maioria das gestantes apresentou ansiedade mínima (35,2%) e depressão mínima (43,3%). A depressão grave foi identificada em cinco gestantes (13,5%) e a ansiedade grave em uma (2,7%). O comprometimento do apego materno-fetal pode implicar em risco para depressão pós parto (DPP), especialmente em gestantes de alto risco. A presente investigação visou contribuir para a elaboração de estratégias que viabilizem a promoção da saúde materno infantil.

Covid-19 has made our world virtual. The limiting of personal contact and the use of new technologies has made it more virtual in this time. The time spent with the real world has been almost equal to the time spent with virtual world during the lockdown period. With the advent of new communication technologies, the gap between the real and virtual world have narrowed down. The virtual world has become a reality as people are spending their maximum time with it and consuming much more as compare to earlier times. The virtual world has all the physical characteristics that a real world possess. It represents the actual world and the society we see around. So, it is obvious for us to think there is similarities between the two worlds of women too. Representation of women in the virtual world is the mirror image of the women of real world. This study is done from the time of Covid-19, to understand if women of real world are same as represented in the virtual world or there lies a difference in the representations and their situations. It also discusses the differences, opportunities and challenges of women belonging to both the world. To attain the objectives, case studies of women representing both the world have been done.

Authors: Kusuma Arta Adi
Published: February 2022

The population in this study were all 115 employees of Hotel Muria Semarang. The sample was determined by proportional random sampling technique, with 53 respondents as respondents. The data collection method used is a questionnaire (questionnaire) and documentation method. The data analysis method used in this research is the percentage description analysis method and multiple linear regression. Based on the results of the study, it was obtained that the multiple linear regression equation = 23.857 + 0.180 X1 + 0.94 X2. By using SPSS 16 the results of the F test hypothesis show F count = 16,646 with a significance value = 0.000 <0.05 which means H3 which reads "There is a significant influence of motivation and work environment on employee performance at Hotel Muria Semarang" is accepted. Meanwhile, from the partial hypothesis test (t test) it is obtained that the t count of the motivation variable is 2,619, the t count of the work environment variable is 2,207 where the probability is less than 0.05 then the hypothesis is accepted. The coefficient of determination (Adjusted R2) is 0.376, this means that 37.6% of the employee performance of Hotel Muria Semarang is influenced by motivation and work environment, while the rest is influenced by other variables that are outside the variables studied in this study. The conclusion is that motivation is in the good category, the work environment is in the good category, and the performance of the employees of Hotel Muria Semarang is in the good category. Motivation has an influence on employee performance with a contribution of 12.04%. The work environment has an influence on employee performance with a contribution of 8.88%. Motivation and work environment together have an influence on employee performance with a contribution of 37.6%. Suggestions that can be given in this study are indicators of the need for security, namely the absence of a better future guarantee from the company. It is hoped that the need for security can be overcome, such as by having a pension fund after the work period is over or an old-age guarantee. The indicators of social needs are the lack of interaction between employees at work and the indifferent attitude between employees. It is hoped that social needs can be overcome by the company holding tours or recreation with employees so that relations between employees are closer, creating working groups for employees. From the work environment variables, the weakness in the lighting indicator
An objective method of forecasting thunderstorm over Dundigal airfield and neighbourhood in the pre-monsoon season
Authors: SINGH R. K.
Published: February 2022

In this study an attempt has been made to provide an objective method of forecasting thunderstorm activity over Dundigal airfield and neighbourhood during the pre-monsoon season (March to May). Inter-relationships of a number of meteorological parameters in the context of subsequent convective activity were studied by means of frequency tables. The six parameters, chosen were surface dew point, surface wind direction, Showalter stability index, wind direction at 850 mb, mean mixing ratio from 850 to 700 mb, and convective condensation level. These were combined graphically by correlation technique to form an objective forecasting aid. The method was tested on independent data and the results were found to be in good agreement with the observations. A skill score of 0.72 and a percentage accuracy of 87% were achieved.
A note on the likely areas of establishment of Japanese beetle (Popillia Japonica, Newman) in India
Authors: DUBEY R. C. , VENKATARAMAN S.
Published: February 2022

A climatological study to delineate the areas favourable for the establishment and multiplication of the Japanese beetle shows that the most favourable meteorological conditions for the beetle would obtain in some parts of north Uttar Pradesh, Himachal Pradesh and Kashmir. A longer activity period from May to August may be expected in India while it is only two months in U.S.A. and European countries. The adult feeding period can extend from April to October and hence several generations can be produced. Thus the pest would pose a serious threat to orchard plantations in northwest India.
Radar Study of the Bay of Bengal cyclone of 19 November 1977

Published: February 2022

The severe cyclone which hit the Andhra Pradesh cost on 19 November 1977 was observed by the Cyclone Warning Radar at Madras for about 72 hours. The large range of detectability, the larger radar echo area, tight banding, double eyewall and the high rate of rainfall in the eyewall region all indicate that the storm had an unusually severe intensity on the 17 and 18 of November. There was, however, a general decrease in the total echo area, total areal rainfall, maximum eyewall rainfall rate and maximum cloud top heights in the eyewall from the 18th to the 19th. It is inferred that the storm might have weakened to some extent while still at sea. The eye maintained a nearly constant diameter of 60 km until the storm came close to coast when the eyewall broke up. The storm probably reorganised later with a smaller eye but this could not be observed by radar. The storm motion during the period of radar observation was northwestwards. Precyclone squall line orientation and extrapolation of radar track were found to be good predictors of storm motion but other radar features were not.
