Information Flow Between the Zimbabwe Stock Exchange and the Johannesburg Stock Exchange: A Transfer Entropy Approach
Authors: Nyakurukwa Kingstone
Published: December 2021

The purpose of this paper is to determine whether there was information flow between the stock markets of Zimbabwe and South Africa during the time the Zimbabwean economy was dollarized. The author used econophysics-based Shannonian and Rényian transfer entropy estimates to establish the flow of information between the markets in tranquil periods as well as at the tails of return distributions. The only significant Shannonian transfer entropy estimate was from Johannesburg Stock Exchange (JSE) resources index to Zimbabwe Stock Exchange (ZSE) mining index. The findings show that the only significant tail dependence was between JSE All Share Index (JALSH) and ZSE Mining on the one hand, and between JSE Resources and ZSE Mining on the other hand. However, the magnitudes of the effective transfer entropy values are relatively low, showing that there are weak linkages between the Zimbabwe Stock Exchange and the Johannesburg Stock Exchange. The lack of significant information flows between the exchanges of the two countries offer opportunities to fund managers for portfolio diversification. From a government point of view, it is imperative that the tempo of economic and political reform be accelerated so that integration between the markets can be fast-tracked. Integrated markets will benefit Zimbabwe as this will reduce the cost of equity and accelerate economic growth.
Does Emigration Hurt the Economy? Evidence from Lithuania
Authors: Kasnauskiene Gindrute , Kavalnis Remigijus
Published: December 2021

This study explores the economic impact of population emigration with special reference to the case of Lithuania. For this reason, we developed a SVAR model and applied related IRF and FEVD tools using quarterly data for the period of 2001-2020. Our findings reveal that a positive shock in emigration is related to lower unemployment. It is also found that the increased emigration is linked to higher real wage growth but with a lower confidence interval. Moreover, our estimates suggest that international out-migration increases real GDP growth in the short term, with no significant effects in the long run perspective. Finally, we found that most of the emigrants-to-be were inactive for a long term prior to departure, which offers a new look into the consequences of Lithuanian emigration, suggesting that the economic losses of emigration could be overstated. This study contributes to the knowledge about the impact of emigration on the economy and specifies directions for further studies in the field.
Consumer Entitlement Inventory: A Scale Extension and Application to the Vietnamese Retail Context
Authors: Van Nguyen Si , Vo Minh
Published: December 2021

The consumer entitlement (CE) construct is a key variable in the exchange process in retail environments. The original Consumer Entitlement Inventory (CEI) was developed and applied within Western cultural boundaries. The main contribution of this study is the extension of the original CEI to better fit the Vietnamese context and to demonstrate its applicability in the context of an emerging economy with a Confucian culture. The study also contributes to expanding the range of identified boycott motives in the literature and clarifying their mechanism via social exchange theory. The extended CEI scale was tested using exploratory factor analysis and confirmatory factor analysis, using a sample of 603 respondents. Qualitative and quantitative research results show that the extended CEI has two dimensions, namely intransigence, and demand and distinction, with adequate content, reliability, convergent validity, and discriminant validity. This study also aimed to apply the extended CEI to an exploration of the relationship between CE and willingness to boycott. Research results from another independent study with 450 respondents using a structural equation model confirmed the positive relationship between CE and willingness to boycott. In addition, theoretical implications are discussed.
The Role of Animosity, Religiosity, and Allocentrism in Shaping Purchase Intention through Ethnocentrism and Brand Image
Authors: Kusumawardani Kunthi Afrilinda , Yolanda Monica
Published: December 2021

With the long history of the relationship between Indonesia and China, various sentiments may arise and influence the consumer purchasing decision. This study aims to determine the impact of animosity towards China, religiosity, and allocentrism of the Indonesians on the intention to purchase Chinese brands smartphones, mediated by consumer ethnocentrism and brand image. This study has 215 valid responses and was carried out using SPSS 25. Structural Equation Modelling (SEM) was performed using AMOS 22. The results show that consumer ethnocentrism is significantly influenced by animosity, religiosity, and allocentrism. Brand image can mediate between consumer ethnocentrism and purchase intention. This study gives a better understanding of Indonesian consumer ethnocentrism with animosity towards China, religiosity, and allocentrism, which will affect the Chinese brand image and Indonesians’ intention to purchase the product.

Paper research aim is to identify characteristics of spacious distribution of radioactive- and associated elements in albitites according to depth and ore-level attribution: case study of 35th survey line of Novokostiantynivka deposit. Geochemical characteristics of Novokostiantynivka deposit are defined by presence of upper and lower ore-bearing levels. Geochemical anomalies related to upper ore-bearing level have complex character (uranium, thorium, lanthanum, yttrium, ytterbium, vanadium, and zirconium). At apical part of the deposit (Eastern fault) the albitites of blended type (chlorite, rybekite, aegerine) are dominant. La, Th, Y, and U define geochemical trend. These elements are likely to be related to rare-earth mineralization (monazite, apatite, xenotime), to a lesser extent to thorium and uranium mineralization with subordinate zircon. At deeper levels (Western fault) albitites’ mineral composition becomes more monotonous of rybekite-aegerine, and aegerine. The lead elements are Zr, Y, V, U, Th; Zr and Y noticeably dominate over other elements. Both elements and, maybe, part of U are related to zircon (malacon) which is predominant over rare-earth and thorium mineralization. Geochemical anomalies related to lower ore-bearing level are distinctive with monometallic (uranium) trend. The albitites of large column-like body have rybekite-aegerine, or aegerine mineral composition; phlogopite occurs often. Associated elements like Th, La, Y, Yb, V, Zr specific to albitites of upper ore level are not characteristic to deeper one. Based on seldom minor Th, La, and Y content spikes, rare-earth and thorium mineralization is immaterial. Regarding Zr and V, their contents are not over but most of the time less than background values. Apparently, zircon is not formed in albitites of lower ore-level; vanadium content in darkcolored minerals becomes insignificant, and single lead element is uranium. The most essential feature of Novokostiantynivka deposit is a succession of complex mineralization with monometallic one with depth.

Authors: Bain Lisa , Sivakumar Dharshi , McCallie Katherine , Balasundaram Malathi , Frymoyer Adam
Published: December 2021

BACKGROUND

A serial clinical examination approach to screen late preterm and term neonates at risk for early onset sepsis has been shown to be effective in large academic centers, resulting in reductions in laboratory testing and antibiotic use. The implementation of this approach in a community hospital setting has not been reported. Our objective was to adapt a clinical examination approach to our community hospital, aiming to reduce antibiotic exposure and laboratory testing.

METHODS

At a community hospital with a level III NICU and >4500 deliveries annually, the pathway to evaluate neonates ≥35 weeks at risk for early onset sepsis was revised to focus on clinical examination. Well-appearing neonates regardless of perinatal risk factor were admitted to the mother baby unit with serial vital signs and clinical examinations performed by a nurse. Neonates symptomatic at birth or who became symptomatic received laboratory evaluation and/or antibiotic treatment. Antibiotic use, laboratory testing, and culture results were evaluated for the 14 months before and 19 months after implementation.

RESULTS

After implementation of the revised pathway, antibiotic use decreased from 6.7% (n = 314/4694) to 2.6% (n = 153/5937; P < .001). Measurement of C-reactive protein decreased from 13.3% (n = 626/4694) to 5.3% (n = 312/5937; P < .001). No cases of culture-positive sepsis occurred, and no neonate was readmitted within 30 days from birth with a positive blood culture.

CONCLUSIONS

A screening approach for early onset sepsis focused on clinical examination was successfully implemented at a community hospital setting resulting in reduction of antibiotic use and laboratory testing without adverse outcomes.
El uso de Twitter por los miembros de la Asamblea Legislativa de Puerto Rico como medio de participación política
Authors: Del Rosario-Camareno Ernesto J. , Gómez-Hernández Sheika
Published: December 2021

En este artículo se indaga sobre la posible interacción de los legisladores de Puerto Rico con sus constituyentes en Twitter, a manera de determinar si se establece una participación política. A través de un acercamiento mixto se trabajaron dos fases, en donde se identificaban y categorizaban las cuentas de Twitter de los legisladores, y luego se realizó un análisis de contenido de los tuits en los periodos seleccionados. Mientras el indicador de participación política sirvió para observar cómo y en qué forma los legisladores interactúan con sus constituyentes, el análisis de contenido de los tuits funcionó como indicador para determinar los temas principales y si establecieron una comunicación dialógica. Se evidenció que los legisladores, aunque capacitados para establecer una participación política en la red, disminuyen sustancialmente el potencial uso de interacción al limitar la participación ciudadana.

Fermentación extractiva de melazas
Authors: Caicedo Luis A. , González Omar , Rico Yolanda , Correal Leonor de
Published: December 2021

Una cepa de Saccharomyces cerevisiae aislada de levadura Fleishman, fue adaptada para fermentar melaza en presencia de solventes como Kerosene, destilados de gasolina y n-Heptano, Fueron realizados ensayos iniciales para seleccionar el solvente, observándose que el Kerosene presenta menor efecto inhibitorio. La fermentación de la melaza fue realizada con mezclas de solvente y mostró en relaciones 1 a 1 y 4 a 1 respectivamente y concentraciones iniciales de azúcar equivalentes a 12 y 16 grados Brix. Se corroboró el efecto inhibitorio que ejerce el producto (etanol) en la fermentación, debido a que concentraciones altas de solvente producen mayor conversión del azúcar y por consiguiente mayor rendimiento. Para altas concentraciones de azúcar la conversión está limitada por la solubilidad del alcohol en el solvente. Comparando los coeficientes de distribución de la mezcla etanol-agua-kerosene con los obtenidos en la mezcla mosto fermentado-kerosene, se pudo observar una mayor solubilidad del etanol en la fase orgánica de la última, debido probablemente a la presencia de sales en el medio.

Published: December 2021

El artículo plantea la problemática en la toma de decisiones terapéuticas frente al niño prematuro extremo, en particular, aquel de menos de 25 semanas de gestación, sometido a tecnología de soporte vital avanzado. Para ello, se tuvieron en cuenta tanto su pronóstico como las posibles secuelas. Expone la forma en que las decisiones pueden ser tomadas y la manera en que los actores se pueden involucrar. La perspectiva ética de los actos terapéuticos analiza los argumentos de calidad de vida y mejores intereses para el paciente. Adicionalmente, intenta analizar las repercusiones para la salud pública, centrándose particularmente en la asignación y distribución de recursos. Se concluye que la toma de decisiones no puede ser realizada aisladamente por el equipo de salud, sino que requiere de la participación de los padres. El uso desproporcionado de tecnología diagnóstica y terapéutica conllevaría para las niñas, niños y sus padres importantes cargas de sufrimiento y gastos tanto individuales como para el Estado. La calidad de vida debe ser ponderada y adoptada como criterio analizando el mejor interés para el niño, sus padres y la sociedad, en defensa del bien común y equidad.

Published: December 2021

Bajo las actuales circunstancias de la pandemia por COVID-19 y dada la posibilidad de colapso de los sistemas de salud debido al aumento de contagios a nivel mundial, es necesario establecer el tiempo en el que un paciente infectado con SARS-CoV-2 mantiene la condición de contagiante. Determinar con mayor precisión la fase de transmisibilidad del agente infeccioso servirá para estandarizar el periodo de aislamiento del paciente y evitará la diseminación del virus a nivel comunitario y su reincorporación a la actividad laboral de forma segura. Mediante pruebas moleculares se ha establecido que el ARN viral es detectable en el tracto respiratorio desde 2 a 3 días antes de la manifestación de síntomas, alcanzando su máximo nivel al inicio de los síntomas y disminuyendo progresivamente en los siguientes 7 u 8 días en la mayoría de pacientes. Sin embargo, la detección persistente del ARN viral mediante RT-PCR no necesariamente significa que el paciente conserve su capacidad infectante. Se ha reportado que en casos leves y moderados de la COVID-19, la capacidad replicativa del virus perdura hasta el día 9 desde el inicio de síntomas, mientras que, en casos severos y críticos, se prolonga hasta el día 20 desde la aparición de síntomas. Actualmente, las estrategias propuestas por la OMS y los CDC para definir el tiempo de aislamiento de los contagiados, se basan en el tiempo de manifestación de síntomas y la evolución clínica del paciente.
How to promote the pragmatic awareness and avoid the fossilization phenomenon through a role play activity in English as a foreign language classes
Authors: Oliveira Patrícia Flasmo de
Published: December 2021

Many people, even after spending a lifetime studying a foreign language are prone to get stuck in a certain grammatical domain no matter the efforts made and the amount of the target language input offered in the classroom. Unfortunately, the great majority who pursuits their dreams to be the closest possible to a native like speaker, the lack of ability to analyze and synthesize linguistic elements makes them persist in the same errors, establishing a phenomenon known as Fossilization in their learning process. In fact, Fossilization can occur in all learning process levels: phonological, grammatical, lexical and pragmatic and the errors made seem to be similar from individual to individual. In an attempt to avoid this Fossilization process concerning the pragmatically ability to communicate, this article aims to present a suggestion of a role-play activity involving strategies to enhance pragmatic awareness related to politeness theory.

Published: December 2021

The work is devoted to the numerical study of indoor microclimate. Accurately predicting the distributed microclimate inside the residential space equipped with a microclimate control system called the «smart house» allows to save thermal energy significantly. Mathematical modeling was carried out by means of the Navier-Stokes equation, the energy equation, the continuity equation. The system of equations used was closed using the k-w-sst turbulence model. The resulting numerical solution was performed in the Code_Saturn, which has a free license. The Salome free software package was used to build a grid. In this context, a second–order scheme (SOLU) was used to resolve the velocity field, a MULTIGRID scheme was used for the pressure field, automatic settings were used for the kinetic energy of turbulence and her dissipation and for the temperature field, the maximum number of iterations for each cycle was equal to 10000, the Solver Precision accuracy was 10-8. The SIMPLEC algorithm is used to obtain a connected solution of the momentum balance and continuity equations. The paper provides an example of numerical solution verification, which is showed the relative temperature deviation from the values obtained by other authors was no more than 0.8-1.2%. Numerical simulation of the air velocity field in the residential space showed values from 0.12 to 0.15 m/s. Based on the results of the obtained solution, an analysis of the saving of thermal energy was carried out when regulating the supply of heat.

The aim was to: (1) compare changes among primary and secondary implant stability between immediate and early loaded implants in edentulous maxilla, (2) evaluate oral health-related quality of life (OHRQoL), and (3) determine patient satisfaction with 6 implant supported fixed full-arch dentures. A prospective, randomized controlled clinical trial was conducted on 24 edentulous maxilla patients. The BLT SLActive implants in 12 patients were immediately loaded with temporary restorations while 12 patients did not receive temporary restorations. Definitive (final) dentures were delivered to all patients after 6 weeks. Stability of the implants were assessed by insertion torque (IT) and resonance frequency analysis (RFA). Oral Health Impact Profile-19 (OHIP-19) questionnaire was used to evaluate OHRQoL and a visual analogue scale (VAS) was used for patient satisfaction. The IT value of implants assigned for immediate and early loading group was 27.17 ± 9.55 Ncm and 25.01 ± 11.06 Ncm, respectively. Changes in implant stability from baseline to week 6 were similar in both groups when measured by Penguin (P = .881) and Ostell (P = .828). Patients in the immediate loading group reported significantly lower OHIP physical pain scores (P = .016) and OHIP psychological disability score (P = .046), and the patients reported significantly higher VAS function score (P = .009) and VAS esthetics score (P = .009). Implant loading protocols do not have a significant effect on the change in implant stability 6 weeks after implantation; however, immediate loading significantly improves OHRQoL as well as satisfaction of patients with maxillary edentulism treated by fixed full-arch dentures. Future trials will determine the role of immediate loading protocol in clinical scenarios with various amounts of available jaw bone using different numbers of implants to retain a fixed prosthetic restoration in the edentulous maxilla.
Clinical Efficacy and Safety of Ivacaftor/Lumacaftor Combination in Patients with Cystic Fibrosis: International Studies Review
Authors: Kashirskaya Nataliya Yu. , Petrova Nika V. , Zinchenko Rena A.
Published: December 2021

Cystic fibrosis is an autosomal recessive disease caused by structure abnormalities in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. It is characterized by severe course and poor prognosis without or with insufficient treatment. Approval of pathogenetic therapy medications, CFTR modulators (potentiators and correctors), for clinical use in 2012 in the United States has reduced mortality from this disease. This article provides the overview of studies on clinical efficacy and safety of ivacaftor/lumacaftor combination (Iva/Lum) — the first licensed CFTR modulator medication for homozygous patients with F508del variant. It was shown that Iva/Lum increases lung function, reduce the number of acute conditions of bronchopulmonary process (including those that require antibiotics and hospitalization), partially restores pancreas exocrine function, increases body weight and mass growth index, and improves quality of life. It allows considering it as favorable effect on the course and prognosis of cystic fibrosis. It was also noted that the early onset of the drug administration (from the age of two) positively affects the prognosis of the disease, increasing life expectancy and improving quality of life.

Mucopolysaccharidosis type II (MPS II; Hunter syndrome) is X-linked hereditary disease from the group of lysosomal storage disease. Its prevalence is 3–7 cases per 1 million live-born boys. MPS II occurs due to the deficiency of iduronate-2-sulfatase enzyme because of pathological changes in the structure of the IDS gene. Enzyme deficiency leads to the accumulation of glycosaminoglycans (GAGs), dermatan sulfate and heparan sulfate, in lysosomes. This leads to the damage of various organs and systems in the body with further development of clinical picture of the disease: coarse face, recurrent infections of upper respiratory tract, hearing loss up to deafness, cardiovascular and respiratory systems pathologies, hepatosplenomegaly, musculoskeletal system abnormalities, low growth, central nervous system damage. Enzyme replacement therapy with idursulfase, that was introduced in clinical practice 15 years ago, has significantly changed the quality of life of these patients. Idursulfase is purified form of natural lysosomal enzyme iduronate-2-sulfatase obtained via human cell line. Exogenous enzyme entry promotes GAGs catabolism in cells. This article provides outcomes analysis of foreign and Russian studies on the efficacy and safety of this medication, and its effect on MPS II patients survivability.
Traditional Dance in the Memory of Inpatriates and Diaspora (on the Example of the Circassians of Turkey and Kosovo)
Authors:   Adyghe State University, Sokolova A. N.
Published: December 2021

The issue of the formation of different dance systems in one ethnic group (Circassians-Circassians), divided almost 200 years ago, representing the Circassian diasporas of Kosovo and Turkey, is considered. The reasons for the loss of cultural memory among representatives of the diaspora and its regeneration as a result of the resumption of cultural contacts with the Russian Adygs are investigated. The fragmentation of the cultural memory of the Circassian diaspora in Turkey is emphasized, associated with the formation of different dance systems among the Circassians (Shapsugs and Abadzeks) of the Black Sea coast (Duzce, Samsun) and the Circassians (Kabardians and Khatukays) of Kayseri. The difference in dance systems is also typical for the eastern and western Circassians in Russia. However, this fragmentation acts as an indicator of local diversity and, consequently, a source of cultural wealth and a resource for genre and dance exchange.

Published: December 2021

AbstractHemp (Cannabis sativa L.) was used for textile and cordage more than 4000 years. The cultivation of industrial hemp declined in the 19th century but it remains one of the oldest crops in history. Despite of the decline, nowadays interest for this crop has recently been renewed within various European countries (Roman et al., 2012). The aim of the research is to observe the evolution of production values and physical parameters (MMB- grain) under the influence of different seeding space and organic fertilization level recorded in some hemp varieties approved in Romania, with a low level of THC.

Evaluation of the early maize (Â Zea mays L.) germplasm is important for the development of new inbred lines and commercial hybrids adapted to cooler regions. Choice of populations to use in improving elite maize hybrids is a critical decision in maize breeding programs. Our objectives were: I) to examine the variation for earliness in a set of 256 local populations, 56 synthetic populations and 504 inbred lines; II) to determine the performance and heterosis of this germplasm; III) to identify the genotypes (local populations, inbred lines) for the initiation of the primary cycle for directional selection for the studied characters. Seven synthetic populations and six inbred lines formed the base material of this genetic study. The seven synthetic populations and their topcrosses to four inbred lines: two flint inbred lines (TD 233 and CO 255) and two dent inbred lines (TC 184 and TC 209) and also a diallel type p(p-1) system with 30 single-cross hybrids and the six parental forms were evaluated at four environments in: two years 2009 and 2010 and two locations Turda and Targu- Mures. The highest values of additive effects for grain dry matter content were recorded at: Tu Syn Mara (ÄÂ n = +1.80), Tu SRR 5D (2I) (1) (Än = +0.62) and Tu Syn 1 (Än = +0.45). Therefore, Tu Syn Mara, Tu SRR 5D (2I)(1) and Tu Syn 1 produced hybrids with the most early maturity. The highest general combining ability (GCA) for dry matter accumulation in grains has registered the inbred lines TC209 (Ä = +1.36) and TC208 (Ä = +0.71).

The European Unionâ€™s policies regarding the energy security impose to the European countries to take urgent measures because of the global energy demand which is growing rapidly. The ambitious target approved by the renewable energy directive is that 20 % of the final energy consumption has to be provided by renewable sources by 2020. The technological transfer from west to east Europe encourages the eastern countries with a high agricultural potential to develop political, economical, and social strategies to replace the fossil resources with the renewable materials. The main goal of the European countries is to promote the clean energy technologies. Thus, the share of renewable resources such as wind, solar, biomass, geothermal, biogas, etc. has to be increases with 24 % of the final energy consumption compared to the overall EU target of 20 %. The current work emphasize the technological state and perspectives of the biogas production of the Romanian country in comparison with the leader country in Europe, Germany.

An important factor in sustaining agricultural yield, mineral fertilization is at the same time one of the factors that causes changes in the chemical characteristics of the soils. Nutriment mobility in the soil is different: it is higher in the nitrogen case and lower in that of phosphorusâ€™. We assessed the changes in the macroelement content of the upper soil horizon when applying mineral fertilizers on winter wheat crops. We tested different doses and combinations of complex mineral fertilizers, NPK (S) fertilizers with zinc [15/15/15(+3+Zn)] and ammonium nitrate (35:0:0). The determinations were made for two depths, 0 - 10 cm and 10 - 20 cm, in order to observe the mobility of the nutrients for each soil profile. Nitrogen content vacillates between 0.15 -Â 0.25% Â± 0.008 for 0 - 10 cm depth and 0.16 -Â 0.23% Â± 0.006. Phosphorus is found between 25.8 - 54.64 ppm Â± 3.109 for a depth of 0 - 10 cm and 30.8 - 28.14 ppmÂ Â± 1.406 for 10 - 20 cm. Potassium content varies between 193.8 - 384.64 ppm Â± 25.627 for the depth of 0 - 10 cm and 205.45 -Â 327.14 ppm Â± 15.135 for the depth of 10 - 20 cm. While analysing the results on the macroelement content and mobility in the soil horizon under research in terms of multiple correlations, we got very strong positive correlation for nitrogen and potassium and weak correlation for phosphorus.

The article presents a proposal for the placement of workshop modules for visual artists and artisans from Iasi on the left banks of the Bahlui River. Here, the artists will conduct their creative activities and also fulfill the function of exhibition and sale. Ample decks link the modules between them and with the river, creating the premises for a wide range of open-air activities.The Bahlui River that flows through the city of Iasi is currently the object of a major project for riverbed consolidation in order to prevent floods, thus offering the opportunity to rehabilitate this site with landscaping that would better integrate the river with the town. The path, on the banks of the river, on the section connecting the Podu Ros neighborhood to the Tudor Vladimirescu complex is rather monotonous. Apart from benefiting from the intense pedestrian traffic, the goal for the modulesâ€™ placement is to achieve a space to mark the youthful character of the area, and that would constitute a landmark. The concept behind the project is the linden tree. The locationâ€™s natural landscape is embellished by the presence of linden trees, so, with this project, it was intended to mimic and reflect this symbol in a modern manner, incorporating it in architecture with an exposed structure that interprets this pattern. The article presents an analysis of the location, a review of tendencies for landscape design on the banks of rivers and integration of natural motifs in architecture as well as a detailed presentation of the â€œLinden Romanceâ€ project, focusing on urban rehabilitation issues. Drawing from the successful experiences of other projects, the â€œLinden romanceâ€ project intends to give new life to an important path in the city.
Protection as a Mean to Increase the Sustainability of Wood Structures

Timber has been rediscovered as the building material of choice in recent years, especially in industrialised countries, with the shift of focus on attitudes towards sustainability that include use of natural resources and reduction of COÂ 2 emissions in manufacturing building materials. The environmental qualities of wood (energy-efficiency, healphy building material, ability to be recycled) are matched by few materials used in constructions nowadays, makeing it suitable for a wide range of applications. The combustibility of wood is limiting its use in construction, an important weakness in terms of sustainability, as health and cost issues constitute essential conditions in sustainability assessment methods. Arguably, fire safety constitutes the foremost precondition in choosing wood as the building material. In the case of fire, wood burns on the surface, releases energy and contributes to the fire propagation and spread of smoke. In order to insure greater safety for timber constructions, both passive and active measures of fire protection can be implemented, with the main objectives of improving the security of occupants, limitations of financial loss, protection of the environment in the case of fire. Despite the fear of using wood, the material has a better behavior in terms of fire than assumed, and even with structures more susceptible at fire risks, such as platform framing, measures can be taken in order to improve safety, as further explained in the article. The article analyses the concept of sustainability and the extent to which timber constructions observe these criteria, focusing on the means of increasing safety by fire protection methods with respect to the environment.

The continuous monitoring of the physical, chemical and biological parameters of ponds, and its input and output waters is useful to predict, identify and assess the natural conditions for fish farming, but also be cautions to environmental damages. Water quality assessment can be defined as the evaluation of the physical, chemical and biological nature of water in relation to natural quality, human effects and intended uses. Water Quality Index reduce a great amount of parameters to a simpler expression, to enable an easier interpretation of the monitoring data. The present paper aims is to determined the water quality in five workstation in Jijia and Miletin Ponds (ROSPA0042): Jijia River; Larga Jijia Pond; VlÄƒdeni Pond; HÄƒlceni Dam Lake and Miletin River) with 1052 ha aquatic surfaces, after one year of monthly monitoring the aquatic ecosystems. In the study area there is no industrial source of pollution, diffuse pollution might occur by domestic waste water and agricultural landscape drainage water. Based of the physical-chemical and biological quality parameters, the WQI have been calculated, for each month and station. Summarizing the results, have been obtained the following: for Miletin River WQI varies between 64-78, at Halceni Dam range 65-82, Vladeni Pond 61-81, Larga Jijia 59-81 and Jijia River 41-61, which reveals a medium to good water quality, excepting the Jijia River with a bad to medium state. The novelty brought by using this index of water quality consists in the possibility of using it as a potential indicator of the ecological state of the aquatic ecosystems.

Minimally processed fresh fruit, vegetables and aromatic herbs are a becoming more popular because they satisfy consumersâ€™ need for time and healthy nutrients. But, even applying packaging and refrigeration their shelf life is short. The main quality losses that occur along storage are changes in colour, texture and flavour. In consequence, it is important to establish how these factors affect acceptance and preference of minimally processed fresh plant food. So, the aim of the present paper is to evaluate the effect of storage at refrigeration temperature on some quality characteristics of the most important minimally processed Romanian seasoning herbs. The herbs under study were parsley, dill and lovage. A grid of attributes of fresh herbs was developed. The herbs, sealed in polyethylene bags, were stored at 4Â°C for 12 days. The evaluation of quality characteristics color, texture and flavor, on a scale of 1 to 5 was done in the 1 st, 5 th, 8th and 12day. In order to evaluate the average quality of the herbs, a quality number was used. Starting form herbs scores in the first day, a sensory profile was determined. This was maintained along the storage period. Even though, scores decreased along the storage period, there were no statistically significant differences for any of the parameters under study in the days taken into consideration. Quality number along the storage period do not differ statistically for none of the three herbs. For minimal processed parsley, dill and lovage the maximum shelf-life was estimated to be 23.3 days, 13.7 days and 15.3 days respectively.Â Â  Â th
