Authors: Purwanto Hadziq Najmuddin , Faridi Abdurrahman , Rozi Fahrur
Published: May 2022

There are various levels of students’ achievement in English listening classrooms. Students with different achievement levels (i.e. high achieveing students and low achieveing students) respond differently towards teaching media as well. The aim of this research was to examine the difference of students’ performance, both before and after they were taught by using two English listening teaching media namely DuoLingo mobile application and SPADA (Sistem Pembelajaran Daring Indonesia) platform. As a quantitative research it employed the Experimental factorial 2 x 2 design. Students were divided into two groups based on their achievement classification. The two groups involved in this study were high achieveing students and low achieveing students, and each group were further divided into another two group to be taught with DuoLingo mobile application a for one group and with Sistem Pembelajaran Daring Indonesia platform for the other group. It was found that both Duo Lingo mobile application and Sistem Pembelajaran Daring Indonesia platform does contribute to an increase in students’ performance for both high achievers and low achievers. This research is expected to contribute as a reference for English teachers to choose teaching media to teach listening to students with different achievement levels, and also as a further research regarding media usage for teaching listening to students with different achievement levels.

Published: May 2022

This study aimed to explain the appropriateness of using gambits in studentsâ€™ debate competition, the debate structure realized in the studentsâ€™ debate competition, the contribution of gambits to the studentsâ€™ debate structure, and the ways the students overcome the difficulties of using gambits in the debate competition. To achieve the aims, this study used discourse analysis as the research design. To collect the data, this study used video recorder in observation and interview as the instrument. This study applied Keller and Warner (1988)â€™s theory about conversation gambits and Harvey-Smith (2011)â€™s theory about debate structure to analyze the data. The subjects in this study were 40 undergraduate students (20 teams) from different universities participating in National University Debating Championship (NUDC) 2018 of West Java. Their debate competition (five exhibitions) were observed, transcribed and analyzed. The objects of the study were the studentsâ€™ gambits and debate structure. The findings from observation showed that most of debaters used variety of gambits from opening, linking and responding gambits to deliver their speech appropriately. Most of debaters applied the debate structure in the debate competition. Only one or two debater/s did not apply some parts of the debate structure. The use of gambits gave high contribution to the studentsâ€™ debate structure to support them in making introduction, rebuttals, arguments, and conclusion in their debate speech. The results of interview showed that most of students learned gambits naturally and to overcome the difficulties of using gambits in any situation was by learning and practicing hard to make the speech perfect.

Published: May 2022

In Indonesia, English is learned as a foreign language. Based on study done by Jannah & Fitriati (2016), students had some problems in speaking and one of major problem was anxiety. Students were anxious to speak in English. That situations is commonly found in foreign language class as described by Horwitz, Horwitz & Cope (1986). Moreover, in speaking assessment, students may feel more anxious and this feeling may hinder their speaking skill (Hewitt & Stephenson, 1978; Liu & Jackson, 2008; Wilson 2006; and Woodrow, 2006). This research aimed to design a model of student engaging activities for speaking assessment, specifically in procedure text. This study used the research and development design (R&D) to create an assessment handbook that provided some engaging activities for speaking assessment purpose. There were five phases in this research: defining, designing, developing, implementing and evaluating phase. The results of the research showed the model was not effective. It was obtained that the t-test was less than t table (0,167 < 1,697). Related to studentsâ€™ anxiety level, however, most students had moderate level of anxiety in both experimental (19 students) and control groups (15 students).

This study attempts to explain the use of pragmatic markers in Americasâ€™ Got Talent judgesâ€™ commentaries. The aims of the study are to analyze the existence of verbal and visual pragmatic markers and explain their relationship.  The verbal pragmatic markers are categorized into four types based on the typology of pragmatic markers proposed by Fraser (1996). They are basic markers, commentary markers, parallel markers, and discourse markers. While the visual pragmatic markers divided into thinking face, pointing with gaze and hand movement and smile following the pragmatic function facial gestures from Bavelas & Chovil (2013). This research employed descriptive method with qualitative approach. The object of the study is judges of Americasâ€™ Got Talent season 13 which consist of Simon Cowell, Heidi Klum, Mell B, and Howie Mendel. The study revealed that the judges used the basic markers to express the main message of the comment, commentary markers to express the message contains in the comment toward the main message, parallel markers to express the complement message toward the main message and the discourse markers to express the relation between the main message and the other utterance. The visual pragmatic markers performed also signals certain message related to verbal markers. The judges performed the thinking face to signal the word search, pointing with gaze and hand movement to emphasize the messages convey in utterance and smile to signal pleasure. This research could provide an understanding of EFL learners in using pragmatic markers as a way to improve communication strategy in communication.

Published: May 2022

Griceâ€™s maxims refer to the use of the four conversational implicature and cooperative principle proposed by Paul Herbert Grice (1975). In order to make communication successful, participants have to follow such a principle. This study is aimed at investigating the realization of Griceâ€™s maxims in English teacherâ€™s interaction with male and female students at Bilingual Boarding School and the gender difference that influenced the interaction. The researcher uses descriptive qualitative in analyzing the data. The main instrument used was the researcher herself with the help of the data sheet as the secondary instrument. The object of the study was the teacherâ€™s interaction with male and female students in a different classroom. Then, the data were analyzed in four steps of interactive analysis: data collection, data reduction, data presentation, and data conclusion. To avoid bias or subjectivity, the researcher applied the triangulation of expert judgment. The results show that all the four Griceâ€™s maxims, quality, quantity, relevant, and manner are realized in the teacherâ€™s interaction with male and female students. It was realize by observing and flouting the maxims. In the interaction with male students, there are 4 observances of Griceâ€™s maxims realized they are observed quality maxim, quantity maxim, relevant maxim, and manner maxim. In non-observance of maxims, there are flouted quality, quantity, relevant and manner maxims. On the other hand, the realization of Griceâ€™s maxims in the interaction with male students was observed the quality, quantity, relevant, manner and flouted 2 maxims were quantity and relevant maxim. The results of this study can pedagogically contribute to English language studies. In the classroom interaction in discourse and pragmatic development in general, the realization of maxims (observed and flouted) can be directly included as a good example of the natural authentic of English.

Evaluation of the bending performance of glued CLT-concrete composite floors based on the CFRP reinforcement ratio
Authors: Song Yo-Jin , Baek Seong-Yeob , Yu Seok-Hoon , Kim Dong-Hyeon , Hong Soon-Il
Published: May 2022

A study was conducted on the reinforcement of cross-laminated timber (CLT) concrete composite floors with carbon fiber reinforced plastic (CFRP) to improve its mechanical performance and reliability in wood composite structures. A four-point bending test evaluation was completed on three types of cross-laminated timber concrete composite floors produced with different carbon fiber reinforced plastic reinforcement ratios (33%, 66%, and 100%) on the entire surface of the tensile portion. An increase in the carbon fiber reinforced plastic reinforcement ratio of the composite floors led to an increased bending capacity and a slightly improved yield performance. In the case of a composite floor with a reinforcement ratio of 33%, premature failure occurred in the elastic region due to defects of the CLT such as knots and slopes of the grain. Failure mode analysis revealed that tensile and shear failure coexist when the composite floor has a CFRP reinforcement ratio of 33%. In contrast, reinforcement ratios of 66% and 100% prevented premature failures in the elastic region caused by defects and induced a consistent failure mode. These reinforcement effects reduced the variability in the increased bending capacity of the composite floors and improved the accuracy of the theoretical prediction design via the γ-method. Meanwhile, the shear connections between the cross-laminated timber and concrete via epoxy adhesive exhibited full-composite behavior without being affected by the reinforcement ratio.
Lateral loading behavior of the poplar LVL light wood shear wall

Published: May 2022

Poplar laminated veneer lumber (poplar LVL) is made of fast-growing poplar veneer and structural adhesive, which can well meet the developing requirement of the modern wood structures. This paper mainly focuses on the lateral loading behavior of the poplar LVL shear wall. For this purpose, six shear wall specimens with different opening types were fabricated and tested under the action of monotonic and cyclic loading. Performances were analyzed on the failure pattern, the load-displacement curve, the shear strength, the ultimate displacement, the elastic lateral stiffness, and the energy dissipation. To strengthen the corner joint, an innovative custom-designed hold-down was adopted, and the mechanical performance was also considered. The results showed that the failure of the specimen was mainly due to the yield of the nails and the separation between the stud and the base plate, while the hold-down can greatly improve the shear strength, the ultimate displacement, and the energy dissipation performance of the poplar LVL shear wall without openings. At last, the evaluation formula of the bearing capacity for the light wood shear wall is proposed so as to promote the theoretical basis for the application of poplar LVL in the light wood frame construction.

Authors: Hızal Kamile T.
Published: May 2022

The teaching of wood anatomy is difficult because of the Latin and foreign terminology and the great number of concepts, definitions, terms, and topics that must be learned and that pose difficulties in understanding for most students. The aim of this study was to describe developed traditional methods and adapt new methods in order to explain wood anatomy more clearly to students in both online and face-to-face education. The teaching of the Wood Structure and Identification course at the Vocational School of Forestry was observed and evaluated over the period of two academic terms (one during the Covid-19 pandemic). Teaching methods used in the wood anatomy course were described in detail. Lesson materials and homework were evaluated. When the usual methods were diversified and enriched with visuals and samples brought to the classroom, the students showed more interest in the lesson. As a result of the student drawing and modelling assignments, the lesson was reviewed and reinforced, which enabled the students to focus on the subject and consequently, to understand and learn more easily. It has determined that all teaching methods can be applied easily in both education periods, except using real wood samples method in online education.

Authors: Perçin Osman , Uzun Oğuzhan
Published: May 2022

The strength of a structural system often depends on the interconnections between the components of the structure. Screws are one of the most widely used fasteners in construction. In this study, the screw withdrawal strength of heat-treated scotch pine (Pinus sylvestris L.) samples reinforced with glass and carbon fibers via Desmodur-vinyl trie ketonol acetate adhesive was investigated. Before manufacturing the laminated veneer lumber, the wood samples were subjected to heat treatment at a temperature of 150 °C, 170 °C, 190 °C, and 210 °C for 2 h. Test results showed that the reinforcement fiber type and heat treatment temperatures had a considerable effect on the screw withdrawal strength. Heat treatment reduced the screw withdrawal strength, while the samples reinforced with both fibers had higher screw withdrawal strengths than those without reinforcement. Reinforcement with glass and carbon fibers increased the screw withdrawal strength up to 38% and 49% in the tangential, 13% and 20% in the radial, and 17% and 25% in the axial direction, respectively, compared to solid wood. In addition, the laminated veneer lumber samples reinforced with carbon fiber had a considerable increase in the screw withdrawal strength compared with the solid wood and glass fiber reinforced samples.

Evaluación de pérdidas postcosecha del lulo (solanum quitoense lam.), comercializado en un empaque tradicional
Authors: Muñoz Juan Carlos , Puentes Álvaro , Villamizar C. Fanny
Published: May 2022

Con el fin de evaluar la incidencia del empaque tradicional colombiano sobre la calidad del lulo, se llevó a cabo el estudio de las causas del deterioro postcosecha y la cuantificación de las pérdidas por factores de manejo, empaque y condiciones de transporte, entre fincas ubicadas en el departamento del Huila y la Corporación de Abastos de Bogotá, CORABASTOS. Para ello se identificaron los diferentes empaques regionales comercializados en la central y se caracterizó el mas común, así como la calidad de la fruta en ellos contenida, determinando el porcentaje de daños de precosecha y mecánicos postcosecha. También se cuantificó el daño causado por la profundidad de llenado.
Se encontró que el empaque tradicional más utilizado en el país es el guacal de dimensiones 40 cm x 45 cm x 50 cm, y capacidad promedia de 28 kg, teniendo como única ventaja la resistencia al manipuleo y como desventajas, el ser desechable, de alta relación de peso, RP, empaque/producto y alto daño mecánico por compresión. El lulo se caracterizó físicamente como una fruta liviana, con pesos entre 55 g y 70 g, redondez de 0,95, esfericidad de 0,96, diámetro promedio de 4,9 cm y área superficial de 76 cm.
La madurez del lulo en el guacal fue: maduro 43,2 %, pintón 37,3% y sobremaduro 13,6 %. La calidad varió de producto bueno en 27,1% (fondo) a 67,9% (capa superior), en lulos pintones y maduros. El porcentaje promedio de daños precosecha fue de 12,7% del total, con una intensidad del 1,8% del área superficial. El daño mecánico aumentó de la superficie al fondo del empaque. La evaluación global del empaque a los tres días de cosecha mostró un producto con elevado daño (53,9 %), del cual el 42% por mal manejo y empaque, valor duplicado a los 11 días, con 91,08% de los lulos solo con el daño mecánico, 5,69% con daños de precosecha y solo el 3,39% con lulos buenos. Se concluyó que el guacal no protege la calidad ni la integridad física del producto, no es reutilizable e incrementa el valor por unidad de producto comercializado. Se identificaron como las principales causas de los daños mecánicos postcosecha en la fruta el desconocimiento del índice de cosecha, la eliminación fuerte de la peluza superficial, la ausencia de selección y clasificación, que en solo ocho días pasaron del 42% al 91%, por la profundidad del empaque y la avanzada madurez del producto.
Linealización entrada/salida de sistemas no lineales afines utilizando un filtro
Authors: Delgado Alberto
Published: May 2022

La linealización Entrada/Salida (E/S), dentro del marco teórico del control geométrico, es una técnica madura para sistemas no lineales afines. Esta técnica cancela los términos no lineales de la planta, usando una retroalimentación de estado no lineal, y produce una dinámica E/S lineal para la planta. En este artículo se muestra que un filtro D(s) puede utilizarse para linealizar sistemas no lineales afines en lugar de aplicar una retroalimentación de estado no lineal que requiere conocer las ecuaciones exactas de la planta, su grado relativo, y la medición completa del vector de estado. En este nuevo enfoque el único requisito es conocer el grado relativo del sistema no lineal afín.
Deshidrogenación oxidativa de Isobutano
Authors: Díaz Velásquez José de Jesús , Rodríguez Gerardo , Carballo Luis M.
Published: May 2022

La deshidrogenación oxidativa de alcanos es una reacción interesante debido en gran parte a la diferencia de precio entre los alcanos livianos, y sus correspondientes olefinas, su disponibilidad, y el hecho de que son ambientalmente aceptables debido a su baja reactividad química. Entre las olefinas producidas por deshidrogenación oxidativa del respectivo alcano, se encuentra el isobuteno que es materia prima esencial para la producción de compuestos oxigenados tales como el Metil-terc-butil-eter (MTBE), utilizado como mejorador de octanaje y fuente de oxígeno en mezclas de gasolinas. Por esta razón y porque además el isobuteno es una materia prima importante para las industrias química, petroquímica y de polímeros, su demanda en los últimos años ha estado en constante crecimiento. El interés en la deshidrogenación oxidativa, en general, y del isobutano, en particular, radica en la búsqueda de catalizadores más activos y selectivos con mejor rendimiento de producto para operar a condiciones menos severas y la posibilidad de desarrollar nuevos procesos con menor impacto ambiental y bajos costos atractivos desde el punto de vista industrial.

Authors: Amaya Jeceny , Tristancho Andrés , Sánchez Castellanos Francisco José
Published: May 2022

The present work studies the possibility of using two solid industrial wastes TERMOPAIPA'S fly ash and ECOPETROUS FCC catalyzer waste in removing and recovering chrome from tanneries’ liquid effluent. Fly ash was subjected to two alkaline hydrothermal treatments for obtaining zeolytic structures having better properties; waste catalyser was calcined for eliminating surface coke. Solids were characterized following treatment including DRX, BET area and CEC. A colorimetric method was standardized for determining chrome in solution; a response surface experimental design was implemented for finding optimum removal conditions. The most efficient adsorbent was fly ash treated with increased NaOH concentration; optimum conditions for removing chrome were: 58 minutes at 36°C, 5.9 pH and 31% w/v solid removal. When reused, it was found that the two batches of treated fly ash became saturated following 6 cycles of use, whilst original ash and FCC catalyzer became saturated the second time they were used. Four de-absorbent agents were used for recovering chrome from adsorbent product, H2SO4 0.6 M being the best. Field trials showed that removal efficiency became reduced by the effect of other contaminants, depending on the solution’s initial concentration.

Summary. Due to various factors, the chances of infectious disease
emergence or re-emergence have increased in the 21st century, thus, the
likelihood of new emerging pandemics has also increased. The COVID–19 pandemic,
which appeared in 2019, has highlighted that certain new and re-emerging
infectious diseases – in the case of lack or delay in effective measures – can
spread very rapidly. The main tool for the fight against infectious diseases is
immunization through vaccination. While focusing on the personal health, public
health, economic and societal benefits of a lifelong immunization strategy,
especially in light of the aging society, the goal of this paper is to present
the benefits of vaccines. In order to increase the added value of vaccinations
it is recommended to create a lifelong immunization strategy. Our paper

practical steps towards implementation. Orv Hetil. 2022; 163(14): 535–543.
Road Infrastructure of the Region As a Rental Factor
Authors:   Kuban State Technological University, Pastukhov Maksim
Published: May 2022

One of the important components of agriculture is the transport network, which affects the productivity of agricultural production along with other spatial factors. This influence of road infrastructure is of a rental nature and is a rental factor, and there were factors that affect both the road infrastructure and agriculture, such as terrain conditions (steep slope) that do not allow any agricultural activities and hinder road construction. It is possible to assess the influence of the road infrastructure by means of zoning of geographic information systems. The article studied the districts and urban areas of Krasnodar Krai, including the analysis of the share of suitable land for row farming and the ratio of cultivated areas to the area of land actually suitable for agriculture in terms of geomorphology. The share of the area of the districts involved in the production of crop products in the agriculture of Krasnodar Krai was also determined. The ratio of the total inter-settlement roads to agricultural land and the total productivity of agricultural land were determined. Based on these data, it was revealed that the productivity of agricultural production depends on transport infrastructure. Taking into consideration all factors mentioned above public authorities could decide to improve the efficiency of land use, and agricultural producers can increase economic efficiency as well.

Published: May 2022

The sugar industry plays an important role in the Russian economy and the southern Russian regions are the main producers of sugar in Russia (the Southern Federal District ranks the second in the production of white sugar). The specificity of sugar production is expressed in its high dependence on producers of beet raw materials, as well as in the presence of a significant amount of various types of waste, faces many problems of sustainable development in the sugar industry. The purpose of this article is to identify strategic factors for the sustainable development of sugar production, taking into account the challenges and threats of the new reality. In the study of strategic factors of sustainable development of the sugar industry, the authors identify demand factors and supply factors, as well as risk factors and stress factors. It is proved that the main threat to the sustainable development of the sugar industry is currently expressed in the risks of breaking supply chains in the conditions of the crisis caused by Coronavirus. This study focuses on the risk of stability reduction of the supply of beet raw materials. This risk is directly connected with the level of development of beet production in the region. As a result of the analysis, it was revealed that a decrease in the cultivated areas of sugar beet in the Southern Federal District is a stressful factor in the development of sugar industry. To solve this problem, state subsidies are proposed for projects for the development of abandoned agricultural land for beet cultivation. The solution of the problems of environmental sustainability growth of sugar production is associated with the circular economy models. It is concluded that the strategic factors of sustainable development of sugar industry in the South of Russia are directly connected with technological innovations in the agro-industrial sphere of the region, the implementation of which is largely determined by the level of state support for the industry.

Published: May 2022

The importance of investments for the country consists in the economic growth stimulation, attraction of new technologies, increase of jobs and payments to the budgets of various levels of federal system. The article is devoted to the topical problem of investments attraction to Volgograd region and development of corresponding measures for the improvement of the situation in this sphere. In the Russian Federation, investments are distributed unevenly across federal districts and regions. According to the methodology, used by Expert RA company, the bulk of investments is directed to five to seven constituent entities of the Federation, the remaining regions have to make efforts to attract them. In the Southern Federal District, Volgograd region has the fourth place in terms of capital investments after Rostov region, Krasnodar Krai and the Republic of Crimea. According to the Expert RA rating, Volgograd region, like most regions of the country, is characterized by low potential and moderate risk. It is important for the region to make efforts and attract investments from all possible sources: both external and internal. To work with foreign investors, the region needs to use specific measures (personal participation of the governor in project attraction, search for large projects for foreign investors, interaction with the Ministry of Foreign Affairs). The regional administration should pay attention to the successful experience of other regions in investments attraction. The authors suggested measures to increase the investment attractiveness of the region and investment attraction in the near future. They are subdivided into administrative and financial (selective tax evasions). Within the administrative framework, special measures are allocated to attract foreign investors. The regional development strategy for the next period should be project-oriented, taking into account the new industrialization policy.
Development of Local Self-Government in the Agenda of the Decade (Notes from the 19th Strategic Planning Leaders Forum)
Authors:   Institute of Economics of the Russian Academy of Sciences, Buchwald Evgeniy , Valentik Olga ,   Institute of Economics of the Russian Academy of Sciences
Published: May 2022

Despite many unfavourable conditions, in October 2021 it became possible to hold the next scheduled the 19th Strategic Planning Leaders Forum in Saint Petersburg in person and in full scale. In 2021, the key topic of the forum was “Strategic Planning Leaders Forum of the Regions and Cities of Russia: Reality 2020 and Agenda for the Next Decade”. Although the theory, methodology and practice of strategic planning remain the key object of discussions at the forum invariably (for almost 20 years), the approaches for the analysis of this topic at the forum do not remain unchanged. Strictly speaking, two stages can be distinguished here: before the adoption of Federal Law No. 172 on strategic planning (2014) and the entire subsequent period. At the first stage, the provisions which we would like to see in the law on strategic planning were mainly discussed. At the second stage, issues of implementation of this law, ways to ensure the relationship of strategic planning documents and the capacity of its “power vertical” moved into the spotlight. However, it was impossible not to notice that already at the 2019 forum, many key issues of methodology and practice of strategic planning began to be postponed. This shift was even more typical for the full-time part of the 2021 forum. The discussion mainly focused on issues of a private nature, i.e. issues that are no less important, but still clearly do not take into account the fullness of the problems of strategic planning practice in the conditions of growing uncertainty, especially in the context of the “agenda” of the coming decade. Frankly speaking, in many positions this “agenda” was not particularly clarified at the forum, which is naturally related to the specifics of the social and economic situation in the country at the turn of 2020-2021. One of the issues which fully integrated the analysis of the existing situation with a view of its further prospects was Russian local self-government.

On Few Electronic Properties of Nano Wires of Heavily Doped Biosensing Materials
Authors: Das Prabir Kumar
Published: May 2022

With the discovery of quantum Hall effect by Prof. Von Klitzing leading to Nobel Prize in 1985[1], there has been extensive interest in the thermoelectric power (TP) of various technologically important low dimensional compounds. In this paper an attempt is made to investigate the TP
in Heavily Doped Nano Wires (HDNWs) of different bio-sensing materials together with the relative comparison of the said transport features with that of the HDNW compounds. The TP increases with increasing n0 in oscillatory ways. The most important realization is that the
quantum signature in this case is not only totally different but also the variations of the said electronic quantity as compared with that of HDNWs of different compounds excluding bio-materials are also different.

Zinc is one of the most essential trace elements in periodic table which is directly involved in several enzymatic and biological activities in human body. Research has mainly focused in the catalytic and biological applications of Zinc complex; however the fluorescence property and
its co-relation with the 3d and 4f metal ions are hitherto unexplored. In the last decades several fluorescence active Schiff base (H2 L) was synthesised using o-vanillin and ethylene diamine in room temperature stirring. Herein, metal complexes of Zn(II) and Zn(II)-Tb(III) were
synthesised and characterized. Photo physical properties of all these complexes were studied using fluorescence spectroscopy. Interestingly it has been found that the Zn(II) complex shows enhanced fluorescence intensity than the other complexes. However, the fluorescence intensity of Zn(II)-Tb(III)
complex decreases compare to the Zn(II) complex. The chelation enhanced fluorescence plays the major role for the enhanced fluorescence intensity of the Zn(II) complex however the presence of paramagnetic metal centre in Zn(II)-Tb(III) complex decreases the overall fluorescence intensity as
compare to the Zn complex.

ABSTRACT Objective: To analyze the content of the conceptual and operational definitions of the related factors, associated condition and defining characteristics of the nursing diagnosis “Excess fluid volume (00026)” in hemodialysis renal patients. Methods: Methodological study, of the content analysis type, with 49 specialists who reached a score equal to or greater than 5, according to Fehring’s criteria. Thirty elements were evaluated for relevance, clarity, and precision. The experts’ profile was analyzed using descriptive statistics, and the binomial test analyzed the agreement between them in relation to the terms. Results: The main validated indicators were “Oliguria”, “Anasarca”, “Paroxysmal nocturnal dyspnea”, “Dyspnea”, “Change in blood pressure”, “Edema”, “Ingestion greater than elimination” and “Increased central venous pressure”. This shows that this phenomenon is present in this population. Conclusion: 29 elements were validated for relevance, clarity, and precision. This result clarifies the terms that make up the phenomenon, providing a better understanding of the concept; and assists in the accurate diagnostic proposition.

Abstract This study was carried out on pomegranate fruits cv. “Wonderful” with the aim of maintaining fruit quality and water content, reducing weight loss, chilling injury and browning symptoms during cold storage at 5 °C and 90% RH for 60 d followed by simulated shelf life at 20 °C for 14 d. Coating treatments included gum arabic at 5% and 10%, paraffin at 10% and 20%, chitosan at 1% and 2%, and beeswax at 5% and 10%. All conducted coatings treatments significantly maintained fruit quality as compared to the control (uncoated ones). Chitosan at 2% significantly preserved fruit quality, firmness, visual appearance, husk colour, ascorbic acid and anthocyanin content, furthermore it reduced browning, peroxidase enzyme activity and decay incidence. Paraffin at 10% and beeswax at 10% were effective in maintaining fruit water content, in addition to the significant preservation of husk distention using paraffin at 20%, moreover, application of gum arabic at 5% maintained moderate rates of fruit respiration and total soluble solids content as compared to control.
