Published: July 2022

Green residential buildings benefit their owners economically, socially, and environmentally. However, it is not known whether the buyers know the benefits that will be gained ,when they purchase this green residence: it could also be that they are just following the current trend. Therefore, this review was conducted to identify the motivations for green real estate investments in residential properties and propose a conceptual framework for future validation. In relation to that, both past empirical and conceptual studies were reviewed. A total number of 277 articles were found in several e-databases, searched with the following keywords: ‘green residential,’ ‘green real estate,’ ‘green building,’ ‘sustainable building,’ ‘driver,’ and ‘motivation.’ After the filtration phase, 26 full-text articles that are pertinent to the study were selected for review. The review revealed four variables that motivate property buyers or investor-owned to invest or purchase green residential property. These variables concern environmental degradation, financial returns, cost-saving, and social and environmental benefits. Therefore, an informed decision on the benefits received, especially for green residential properties, could affect the resident’s motivation towards the certified residential properties, encouraging more demand for green residential in the market and spurring more green and sustainable development. For further research, the proposed conceptual framework could be tested for model testing and validation.
Application of Groupwise Principal Sensitivity Components on Unbalanced Panel Data Regression Model for Gross Regional Domestic Product in Kalimantan

Published: July 2022

Most robust estimation methods for panel data regression models do not consider the panel data structure consisting of several cross-sections and time-series units. This robust method, which does not consider the panel data structure, can completely remove all observations from a cross-section unit in trimming outlier observations. However, it can cause biased estimation results for the cross-section unit. This study determines the robust estimate for the unbalanced panel data regression model using Groupwise Principal Sensitivity Components (GPSC) by considering grouped structure data. The results were compared with Within-Group (WG) estimation and other robust estimation methods, namely Within- Group estimation with median centering (Median WG), Within-Group Least Trimmed Squares (WG-LTS), and Within Generalized M (WGM) estimators. Comparisons were made based on the Mean Squares Error (MSE) value. In this study, we applied the proposed method to the unemployed and the Gross Regional Domestic Product (GRDP) data at constant prices in Kalimantan, Indonesia. The analysis showed that GPSC was the best method with the smallest MSE value. Therefore, we can consider implementing and developing the GPSC method to detect and determine the robust estimates for the unbalanced panel data regression model because it fits the panel data structure.

Published: July 2022

The simulation configuration and process analysis of the Subcritical Organic Rankine Cycle (SORC) system are carried out for the potential comparison between pure, binary, and ternary zeotropic mixtures of R1234ze(E), R1234yf, and R134a as refrigerant working fluids based on applying the flue gas as a heat source with medium temperature. The compression pressure was selected as an optimized variable input parameter of SORC with the lower limit of boundary condition (1.4 MPa); to mitigate air ingress and sub-atmospheric pressure that led to approach optimum net power output generated. Increasing the compression pressure has a positive relationship with the superheated temperature and the mass enthalpy change in the evaporation and, therefore, in the expansion process. In parallel, the enthalpy and entropy changes in the flue gas and cold water positively correlate with exergy efficiency. So, R1234ze(E)/ R1234yf/R134a with 68.35% and R1234yf/ R134a with 69.29% as the lowest and highest exergy efficiency in the highest compression pressure; furthermore, the SIC consequences of increasing the cost of each component of the SORC system that has a direct relationship with the PPC and the required exchanger area of evaporation and condensation process and generating a net power output of the turbine. As a result, the maximum to the minimum value of specific investment cost (SIC) achieves R134a with 5807402.18-22455670.61 $.kW-1 and R1234yf with 16.82-17.38% reduction, respectively. To sum up, the lowest payback period (PBP) was R1234yf with 302 days.

Authors: Meenakshi
Published: July 2022

Cardiovascular diseases (CVDs) take the lives of 17.7 million people every year, 31 percent of all global deaths. There is considerable overlap in chest pain of cardiac as well as non-cardiac origin. However, vigilant evaluation of characteristics of chest pain in history taking may help overcome this dilemma. This study was sought to identify characteristics of chest pain associated with other symptoms which are due to cardiac reason and to fi nd out association between characteristics of chest pain and other symptoms with the selected demographic variables. The study was conducted among 60 patients of coronary artery disease (CAD). Characteristics of chest pain associated with other symptoms were assessed by structured questionnaires administered through interview schedule. In this study, 40 percent samples had pain on retrosternal side and 20 percent on left side of chest, while 31.67 percent samples had pain location other than retrosternal and left side of chest; 46.67 percent samples had characterized their pain as heaviness, 30 percent as chocking, 20 percent felt burning pain; 42 percent had pain duration of 1-30 minutes, 77 percent samples had pain severity >7 on 0-10 scale, 41.67 percent samples had pain radiation to left arm, 20 percent on right arm, 25 percent to neck, 20 percent having no radiation of pain. 73.33 percent samples had diaphoresis as associated symptoms, 58.33 percent had dyspnea, 53.33 percent had nausea & vomiting, 60 percent had weakness/fatigue. To conclude, chest pain of cardiac origin can occur anywhere in chest and abdomen, which is usually severe in nature and characterised by chocking and heaviness usually associated with nausea, dyspnea, diaphoresis and weakness. So, patient should be carefully evaluated to prevent mis-diagnosis.

Published: July 2022

El trabajo consistió en determinar la concentración de monóxido de carbono (CO) y su relación con el consumo de leña en 39 viviendas distribuidas en 6 barrios de la zona urbana en la localidad de Calzada. Durante una semana y en tres momentos del día se midió la concentración de CO en cada vivienda con el equipo de medición modelo TROTEC BG20 y se cuantificó aleatoriamente la leña por conteo directo. Se determinó la diferencia de las concentraciones de CO y consumo de la leña entre los barrios. El análisis de agrupamiento mostró diferencias en la distribución de la composición de las concentraciones de CO y leña de los barrios y los días de la semana. Asimismo, se determinó que el consumo de leña/persona y el número de personas por familia no influyeron en las concentraciones de CO. Se espera que por un kilogramo de leña adicional que consuma una persona el CO se incrementaría en 442.62 ppm, y si una persona se adiciona en cada familia se incrementaría en 55.85 ppm. El aumento de familias dependientes de leña para cocinar incrementaría las emisiones de CO en viviendas rurales con poca ventilación.

El objetivo de esta revisión de corte etológico es estudiar las diferentes características de la pastura en una pradera y analizar la respuesta del comportamiento durante el pastoreo. Se busca analizar los factores de la pastura que pueden llegar a influir en la cosecha de alimento, durante el consumo de pastura por parte del rumiante. Uno de estos factores puede llegar a ser la estructura de la pastura, por lo que existen actualmente teorías convencionales que buscan establecer una relación entre estos factores, explicándoles desde un ángulo metabólico y físico, pero no tienen en cuenta la influencia que las características "no nutricionales" de la vegetación ejercen bajo condiciones de pastoreo. Dada la importancia de la ganadería lechera en nuestra región, y del impacto que tiene esta actividad sobre el medio ambiente (ocupa los primeros lugares de contaminación ambiental producto de las constantes emisiones de gas metano en las deyecciones animales), es necesario ser más explícitos en las búsquedas y explicaciones que nos permitan conocer mejor los mecanismo que rigen su funcionamiento y poder buscar la manera de hacer más eficiente la producción reduciendo los daños colaterales (al ambiente) propios de esta actividad.

Glioblastoma organoid technology: an emerging preclinical models for drug discovery
Authors: Batara Don Carlo Ramos , Zhou Shuchang , Choi Moon-Chang , Kim Sung-Hak
Published: July 2022

Glioblastoma multiforme (GBM) is the most prevalent type of primary brain tumor among adults, and it has a median overall survival of 12 to 15 months upon diagnosis. Despite significant improvements in GBM research, therapeutic options are still limited and survival rates have not significantly improved. Accordingly, clinical and translational studies are hampered due to the lack of suitable preclinical models that accurately reflect the brain tumor architecture and its microenvironment. Scientists have recently developed cerebral organoids, which are artificial 3-dimensional brain-like tissue. Organoid technology provides new cancer modeling options, which could help us better understand GBM pathogenesis and design personalized treatments. In this review, we summarize recent developments in organoid GBM models, highlighting their advantages in cancer modeling, as well as their challenges and limitations and potential future directions in GBM therapy.

Globalizing geography before Anglophone hegemony: (buried) theories, (non-)traveling concepts, and “cosmopolitan geographers” in San Miguel de Tucumán (Argentina)
Authors: Rainer Gerhard , Dudek Simon
Published: July 2022

Abstract. The relationship between “national” geographical schools and an increasingly globalized geographical theory-building under the logics of Anglophone hegemony has generated critical debate within geography. This paper aims to contribute to current discussions on the development of differential, language-based “schools of thought” in geography and how these are mobilized and de- and recontextualized when they travel beyond their origins. However, it does not focus on the period of Anglophone hegemony but intends to shed a new, historically informed light on the politics of geographical knowledge production. Against this backdrop, we study why, how and with what consequences German geographical knowledge traveled to Argentina in the 1940s – the end of the “German hegemony” – following the employment by the National University of Tucumán (UNT) of the four German geography professors Wilhelm Rohmeder, Gustav Fochler-Hauke, Fritz Machatschek and Willi Czajka, all of whom had been institutionally and ideologically entwined with National Socialism. Firstly, we show that the epistemic differences between “national” schools of geographical thought – skillfully juggled by the geographers we analyze here – can provide an opportunity for the successful de- and recontextualization of theory. Secondly, we argue that boundary spanning and the traveling of theory beyond their geographical origins – largely (implicitly) viewed as progressive – should always be put in context(s) and assessed more cautiously from a normative point of view.

Abstract. A widespread increase in tree mortality has been observed
around the globe, and this trend is likely to continue because of ongoing
climate-induced increases in drought frequency and intensity. This raises
the need to identify regions and ecosystems that are likely to experience
the most frequent and significant damage. We present SurEau-Ecos, a trait-based,
plant hydraulic model designed to predict tree desiccation and mortality at
scales from stand to region. SurEau-Ecos draws on the general principles of the SurEau model
but introduces a simplified representation of plant architecture and
alternative numerical schemes. Both additions were made to facilitate model
parameterization and large-scale applications. In SurEau-Ecos, the water fluxes from
the soil to the atmosphere are represented through two plant organs (a leaf
and a stem, which includes the volume of the trunk, roots and branches) as
the product of an interface conductance and the difference between water
potentials. Each organ is described by its symplasmic and apoplasmic
compartments. The dynamics of a plant's water status beyond the point of
stomatal closure are explicitly represented via residual transpiration flow,
plant cavitation and solicitation of plants' water reservoirs. In addition
to the “explicit” numerical scheme of SurEau, we implemented a “semi-implicit”
and “implicit” scheme. Both schemes led to a substantial gain in computing
time compared to the explicit scheme (>10 000 times), and
the implicit scheme was the most accurate. We also observed similar plant
water dynamics between SurEau-Ecos and SurEau but slight disparities in infra-daily
variations of plant water potentials, which we attributed to the differences
in the representation of plant architecture between models. A global model's
sensitivity analysis revealed that factors controlling plant desiccation
rates differ depending on whether leaf water potential is below or above the
point of stomatal closure. Total available water for the plant, leaf area
index and the leaf water potential at 50 % stomatal closure mostly drove
the time needed to reach stomatal closure. Once stomata are closed,
resistance to cavitation, residual cuticular transpiration and plant water
stocks mostly determined the time to hydraulic failure. Finally, we
illustrated the potential of SurEau-Ecos to simulate regional drought-induced mortality
over France. SurEau-Ecos is a promising tool to perform regional-scale predictions of
drought-induced hydraulic failure, determine the most vulnerable areas and
ecosystems to drying conditions, and assess the dynamics of forest
flammability.

Abstract. State-of-the-art Earth System models typically employ grid spacings of O(100 km), too coarse to explicitly resolve main drivers of the flow of energy and matter across the Earth System. In this paper, we present the new ICON-Sapphire model configuration, which targets a representation of the components of the Earth System and their interactions with a grid spacing of 10 km and finer. Through the use of selected simulation examples, we demonstrate that ICON-Sapphire can already now (i) be run coupled globally on seasonal time scales with a grid spacing of 5 km and on monthly time scales with a grid spacing of 2.5 km, (ii) resolve large eddies in the atmosphere using hectometer grid spacings on limited-area domains in atmosphere-only simulations, (iii) resolve submesoscale ocean eddies by using a global uniform grid of 1.25 km or a telescoping grid with a finest grid spacing of 530 m, the latter coupled to a uniform atmosphere and (iv) simulate biogeochemistry in an ocean-only simulation integrated for 4 years at 10 km. Comparison to observations of these various configurations reveals no obvious pitfall. The throughput of the coupled 5-km global simulation is 126 simulated days per day employing 21 % of the latest machine of the German Climate Computing Center. Extrapolating from these results, multi-decadal global simulations including interactive carbon are now possible and short global simulations resolving large eddies in the atmosphere and submesoscale eddies in the ocean are within reach.
Drainage and refill of an Antarctic Peninsula subglacial lake reveals an active subglacial hydrological network

Published: July 2022

Abstract. The role of subglacial hydrological networks and subglacial lakes in modulating ice dynamics under the East and West Antarctic Ice Sheets is now relatively well understood. In contrast, little is known about subglacial water bodies under the Antarctic Peninsula Ice Sheet and how these are influencing glacier behaviour. Here we describe the rapid drainage and slow refill of a subglacial lake under Mars Glacier using remote sensing and aerogeophysics platforms. Results suggest drainage of the subglacial lake occurred prior to 2013, resulting in collapse of the overlying ice into the newly formed subglacial cavity. The lake has been refiling since this time, with peak rates of infilling associated with seasonal meltwater activity. We review evidence for similar features elsewhere in the Antarctic Peninsula and discuss whether their appearance marks a threshold shift in the thermal regime of the region’s glaciers and the activation of their subglacial hydrological networks. Collectively, these features show coupling of surface climate processes and the bed and may help explain the strong seasonality seen in glacier flow rates during the annual melt season and the ongoing regional decline in ice mass.
Comparison of the Effect of Aerobic Training and Resistance Training on Body Mass Index and Skinfold Thickness in Overweight and Obese
Adults - An Experimental Study
Authors: Chauhan Kajal Girdharlal , Sheth Megha
Published: July 2022

Introduction: The World Health Organization defines overweight and obesity as abnormal and excessive fat accumulation that may impair health. Exercise has shown to have a positive effect on mood and decreasing cardiovascular risk in normal people. Physical activity favorably alters the body composition. Aerobic exercise and resistance training, even without dietary restriction, may provide positive spin-off to the weight loss effort. Studies of aerobic versus resisted exercises in reduction of body weight is insufficient Indian population.
Method: Demographic and anthropometric data (Age, gender, Body mass index, VO2 max and skin fold thickness) was collected. Aerobic - Group A performed treadmill walking 6 days /week, 20mins / day, Resistance- Group B performed set 1 (Chest press, Arm extension, Leg extension, Quadriceps, Lower abdominals) and set 2 (Elbow flexion, Elbow extension, Retractors, Upper abdominals) on alternate days for 6 days/week. Outcome measures were taken pre and post intervention.
Results: Body mass index, skinfold thickness, aerobic capacity, rate pressure product and quality of life significantly improved p <0.001. Post hoc Bonferroni test showed that aerobic training is better than resistance training for improving body mass index, aerobic capacity, rate pressure product and quality of life where as resistance training is better than aerobic and control group to reduce skinfold thickness.
Conclusion: Aerobic training is more effective than resistance training for body mass index, aerobic capacity, rate pressure product and quality of life where as resistance training is better than aerobic group to reduce skinfold thickness.

Key words: Aerobic training, Resistance training, Vo2max, SF36, Skinfold thickness.
