HPLC determination of Escitalopram in tablet dosage forms
Authors: Balkanski Stefan 
Published: January 2022

Purpose: A simple, specific, precise, and accurate reversed phase liquid chromatographic (RP-LC) method has been developed for the determination of Escitalopram in tablet dosage form.
Methods: The chromatographic separation was achieved on a LiChrosorb C18, 250 mm x 4.6 mm, 5 μm column at a detector wavelength of 270 nm and a flow rate of 1.0 ml/min. The mobile phase was composed of methanol, acetonitrile (70:30 v/v). The retention time of Escitalopram was 5.49 min. The method was validated for the parameters like specificity, linearity, precision, accuracy, limit of quantitation and limit of detection.
Results: The method was found to be specific as no other peaks of impurities and excipients were observed. The square of correlation coefficient (R2) was 0.9999 while relative standard deviations were found to be &lt;2.0%.
Conclusion: The proposed RP-LC method can be applied for the routine analysis of commercially available formulations of Escitalopram.
Typologie des conséquences de la migration sur les stratégies d’adaptation à l’érosion côtière au Sénégal
Authors: Brüning Loïc 
Published: January 2022

La commune de Gandiol, située au nord du Sénégal, est affectée par un phénomène d’érosion côtière engendré par l’action anthropique et accentué par le changement climatique. Les submersions marines provoquent une salinisation du fleuve Sénégal, des sols et des nappes phréatiques, dans une région qui vit essentiellement de la pêche, de l’agriculture et de l’élevage. L’avancée de la mer, couplée à l’augmentation de la salinité, provoquent donc une perte d’habitats et de moyens de subsistance pour les populations locales. Face à ces dégradations environnementales, la migration fait partie des stratégies d’adaptation. Après avoir présenté les contextes environnementaux et migratoires propres à Gandiol, ainsi que le contexte théorique, cet article expose une typologie des conséquences de la migration sur les stratégies d’adaptation aux modifications climatiques. L’utilisation des transferts monétaires de la part des migrants prend différentes formes : diversification des ressources, optimisation des investissements ou protection contre les aléas futurs, mais aussi intensification de l’emploi des femmes.
ENERGY AND WATER PERFORMANCE OF AN OFF-GRID TINY HOUSE IN CALIFORNIA
Authors: Siegner Alana Bowen , Webster Brett , Bolliger Ian , Kammen Daniel M. 
Published: January 2022

ABSTRACTThe impetus for buildings to decarbonize and move towards radical energy and water efficiency is increasingly strong and identified as a priority within the green building sector. The tiny house movement offers an opportunity to both address the challenges of affordable housing and contribute to residential building decarbonization. Tiny houses de-emphasize mass consumption and excessive belongings and have potential to address equity issues such as gentrification by providing living spaces to low-income residents in desirable housing locations. This paper analyzes the Tiny House in My Backyard (THIMBY) project, investigating building sustainability concepts through the design-build-occupy process in a three-year-old structure. THIMBY demonstrates energy and water efficiency technologies inside an award-winning small living space (18.5 m2). THIMBY was designed to reduce energy and water use by 87 and 82% compared to California residential averages. In practice, it has reduced site energy by 88% and has emitted 96% fewer carbon emissions than a 2100 square foot California Energy Commission 2016 Title 24 minimally compliant home. We discuss the differences between design and performance of energy and water systems, which we find offer important lessons for the further expansion of the tiny house movement and other alternative and micro green housing types. We find that optimizing such houses through integration of energy and water saving technologies, home energy management systems, and strong communication between modelers, builders and occupants will be essential to achieving dramatic energy (87%), water (82%), and carbon (96%) savings.
LEED-CI V3 AND V4 GOLD PROJECTS FOR OFFICE SPACES: THE DIFFERENCE BETWEEN SHANGHAI AND CALIFORNIA
Authors: Pushkar Svetlana 
Published: January 2022

ABSTRACTThe Leadership in Energy and Environmental Design (LEED) rating system is currently progressing from version 3 (V3) to 4 (V4) with the aim of reducing environmental damage in the global construction sector. The LEED Commercial Interiors (LEED-CI) subsystem is widely used for office spaces, particularly in Shanghai and California. Comparing Shanghai and California in terms of LEED-CI projects can shed light on the ability of the LEED-CI subsystem to adapt to local green building standards and local environmental conditions. The aim of this study was to assess the difference between V3 and V4 LEED-CI Gold office projects using a comparison between Shanghai and California. The US Green Building Council and the Green Building Information Gateway databases were used to source LEED-CI V3 and V4 Gold office projects. The natural logarithm of the odds ratio and Fisher’s exact 2 × 2 tests with a mid p-value were used to evaluate the binary data, while the Cliff’s δ and exact Wilcoxon–Mann–Whitney tests were used to evaluate the ordinal data. The results show no difference between Shanghai and California in terms of LEED-CI V3 Gold office projects in the five main LEED-CI categories. The shift from V3 to V4 LEED-CI Gold office projects is increasing the difference between Shanghai and California in terms of the following LEED-CI categories: location and transportation, water efficiency, energy and atmosphere, and materials and resources. Therefore, as compared to V3, V4 for LEED-CI Gold office projects demonstrated greater adaptability to local green building standards and environmental conditions.
RESALE OF GREEN HOUSING COMPENSATES FOR ITS PREMIUM PRICING: AN EMPIRICAL STUDY OF CHINA
Authors: Jiang Yongsheng , Xing Yudong , Zhao Dong , Jiao Ruilin 
Published: January 2022

ABSTRACT
Green housing reduces resource consumption and protects the ecological environment. Sustainable buildings and construction have gained increasing attention in the last decade. Many empirical studies have confirmed that green housing imposes a price premium at the presale stage. The high price could be a concern that prevents homebuyers from purchasing green buildings. However, there is a lack of empirical evidence on whether the premium pricing could be compensated for by the resale price. To address this gap, this study establishes a hedonic regression model to estimate the price premium of green housing at the resale stage. The results show that green housing certified with the Chinese Green Building Label (CGBL) offers a 6% price premium compared with non-green housing at the resale stage. The results also show that green housing with a higher level of green certification, e.g., the 3-star CGBL, provides a greater price premium at resale. The findings indicate that home-buyers can obtain financial compensation for the high cost when purchasing a green home. Our findings also indicate that the price premium for reselling a green home is not always enough to compensate for the purchase cost in different cities. Policy recommendations for government promotion of green housing are also discussed.
Le chant des voyelles dans les Papyri Graecae Magicae de l’Empire romain. De la pratique rituelle à l’invention moderne d’une tradition
Authors: Audureau Florian 
Published: January 2022

Au début du xxe siècle s’est imposée l’image d’Épinal du magicien-astrologue. Selon une logique pythagoricienne, celui-ci emploierait la musique pour évoquer les pouvoirs astraux des planètes, et les voyelles que l’on retrouve dans les papyrus de magie gréco-égyptienne serviraient à écrire les notes de la gamme classique. Or, cette « tradition » est avant tout historiographique et ne rend pas compte des pratiques et des dynamiques d’accommodation culturelle. L’analyse détaillée du corpus révèle en effet que l’interprétation astrologique ne relève pas d’une tradition, mais d’une invention ponctuelle et ciblée. C’est au contraire une logique propre aux magi qui sous-tend l’utilisation des voyelles : elles incarnent la puissance du souffle (πνεῦμα) et sa capacité à produire des sons.

Published: January 2022

The effects of Na2EDTA and HNO3 on Ni2+ uptake by Spinacia oleracea seedlings replanted inhydroponic culture in a greenhouse was investigated. Eight week old seedlings, were exposed to various doses of Ni2+ (0, 1000, 2000, and 4000 mg/L) as NiSO4, at (0, 500 and 3000 mg/L) Na2EDTA and ( 0, 500 and 3000 mg /L) HNO3 in different combinations. There was a substantial increase in nickel uptake in chelated treatments (p < 0.05) compared to unchelated treatments of same concentrations of Ni2+. So, chelation enhanced Ni2+ uptake in S. oleracea. During the exposure, antioxidant defense system helped the plant to protect itself from the damage. Due to increasing nickel uptake by the plant, the photosynthetic pigments (i.e chlorophyll a, chlorophyll b and Caretenoids) gradually declined. In this study, Spinacia oleracea Seedlings and contents of the photosynthetic pigments (chlorophyll a, chlorophyll b and Caretenoids) of both chelated and unchelated hydroponic treatments were investigated. Changes in photosynthetic pigments was significant (p < 0.05) with respect to addition of EDTA and HNO3 at different concentration to different concentrations of Ni2+ compared to unchelated treatments of same concentrations of Ni2+. The Ni2+ induced translocation factor was also determined which increased significantly (P < 0.05) with increasing Ni2+ concentrations.

Authors: Sirod Muhammad , Poniman  
Published: January 2022

This research aims to understand the extent of the students’ participation to join the lectures during the Covid-19 pandemic, that requires the lectures to be conducted through online system. In such a condition Inquary-based learning is selected as an appropriate method of learning, in which the students’ independence is needed. The researchers conducted a case study on the application of inquiry-based learning, especially in the subject of Structure-Grammar, at the English Study Program, Academy of Foreign Language St. Pignatelli Surakarta
In the implementation of this method the students are expected to be autonomous learners who must be aware of themselves that they need particular knowledge and consequently, with their own accord they will find any sources from both reference-books and scientific webs. The role of the lecturer is to guide them in such a way that they master the minimum requirements.
The research results show that the students of Semester II give 66.66% of positive response, and those of Semester IV 73.55%. There are more than 25 % of students who do not give positive participation to the lectures due to several obstacles, namely the lack of smart phones, adequate computers or internet access. Although the results are not so satisfying, they can be used as a reference for autonomous learning.
