From the Text to the Reader: An Application of Reader-Response Theory to Robert Browning’s "My Last Duchess"
Authors: ATASOY Emrah
Published: December 2020

Reader-response criticism as a reaction against new criticism has changed the focus from the text to the reader. The reader is no longer deemed a passive agent, but active, participating in the meaning-making process, as reading is a process during which the reader also experiences what the characters experience and feels with him/her. In this respect, the text and the reader interact with each other. Meaning is accordingly created out of this interaction and transaction. A multiplicity of meanings, perspectives and interpretations becomes possible in the process of reading. Each reading of a literary text produces different interpretations. Social, religious, political, psychological and cultural contextual factors and background of the reader have a strong potential to influence the interpretation. Accordingly, the characteristics of the interpretive community are influential in meaning-making. This study will, therefore, discuss reader-response criticism with specific emphasis on Iser’s theory (the implied reader and repertoire) and apply the reader-response theory to Robert Browning’s poem "My Last Duchess".

Published: December 2020

El presente trabajo de investigación, tuvo como objetivo evidenciar a través de vestigios antropológicos y arqueológicos quenuestra lengua materna macro regional, el kichwa del Chinchaysuyu, tiene un origen remoto. Tiene su origen en losmachay runa que fueron nuestros primeros ancestros, nuestros primeros aukillus del primer tronco del árbol genealógico. Apartir de los machay runa de Lauricocha considerado el hombre más antiguo de América, pasando por diversos periodos dedesarrollo evolutivo, de niveles inferiores a superiores se desarrolla nuestra lengua materna hasta configurarse como unalengua macro regional del Chinchaysuyu. El escenario geográfico donde se hablaba esta lengua macro regional fueron losterritorios que actualmente ocupa las regiones de Huánuco, Pasco, Ancash y Lima norte. El método utilizado fue el diálogocon los kichwa hablantes de las provincias andinas de la región Huánuco, que consistió en recoger información mediante laconversación y dialogo. Los resultados nos indican que primero se formaron las lenguas maternas locales de cada grupoétnico, luego por el sistema del trueque o intercambio de productos de una nación con otra, se fue configurando el kichwa delChinchaysuyu como una lengua macro regional. Nuestra lengua materna, surge y se desarrolla a partir de los machayruna que fueron nuestros primeros ancestros. En conclusión, diremos que nuestra lengua materna el kichwa delChinchaysuyu, que tuvo su origen con los machay runa, evolucionan pasando por diversos periodos evolutivos hastaconfigurarse como una lengua macro regional del Chinchaysuyu. El kichwa del Chinchaysuyu, fue una lengua macroregional muy distinto a la lengua aymara y cuzqueña.

Ištar’s Journey: Above and Below
Authors: Bidmead Julye , Love Marilyn
Published: December 2020

Astral information appears in a wide variety of cuneiform texts: astronomical manuals, omen series, reports written by celestial diviners to the kings, letters, prayers, and myths. This paper examines one of these myths, Inanna/Ištar’s Descent into the Netherworld, to trace the parallels between Inanna/Ištar’s journey in the netherworld and the planet Venus. The Mesopotamian goddess Inanna/Ištar is represented in her astral aspect as Venus, who is both the evening star, visible after sunset, and the morning star, visible before sunrise. In the myth, she travels from the ‘great heavens above’ into the netherworld, the ‘great below’, where she passes through seven gates. At each gate, she is symbolically stripped of her divine radiance (mêlammū) by the removal of her clothing and adornments. She is held prisoner by the queen of the netherworld, her older sister, Ereškigal. During the goddess’ captivity, procreation and fertility of the land cease. She is eventually rescued and released in exchange for her lover, Dumuzi/Tammuz, who must reside half of the year in the netherworld in her place. Though the myth is traditionally understood as a seasonal aetiology, with its familiar ancient Mediterranean dying-rising god motif, and as the Mesopotamians’ conception of afterlife, using iconographic representations and linguistic comparisons with the astral omen texts, another interpretation explaining the movements and periodic disappearance of Venus is noticeable.
Clava Cairns, Midwinter Sunset and the Minor Lunar Limit
Authors: Esaroth J. Anna
Published: December 2020

This is a study of the Early Bronze Age cairns at Balnuaran of Clava, near Inverness, Scottish Central Highlands, from the perspective of skyscape archaeology. The site’s solar orientations link it with Maeshowe in Orkney. The role of lunar limits is discussed with special reference to Balnuaran of Clava Central and its rays, which link the site to Stonehenge in Wessex. New alignments are investigated, in order to verify skyscape phenomena and integrate them with previous academic research. The importance of seasonal alterations in light and darkness leads to a suggestion that Clava monument-types may be qualitatively different. Passage-graves appear to be associated with midwinter sunset, the nearest new Moon, minor lunar limits and darkness, although light is still significant. Conversely ring-cairns seem to be associated with sunrise, the midsummer full Moon, major lunar limits and light, yet they have dark connotations, leading to conclusions that the role of light and darkness is paramount in understanding these monuments.
‘Gates of Heaven’: Significance of the Signs of Cancer and Leo on French Medieval Portals
Authors: Lemcool Ivana
Published: December 2020

Images of the Zodiac adorn numerous portals of medieval churches, often together with representations of the Labours of the Months. It has been noted that among the Signs, Cancer and Leo occupy prominent positions, particularly in churches in modern-day France, where they can be seen at the summits of archivolts or at the top of door jambs. This occurence has mostly been regarded as a reference to the summer solstice, taking place in the sign of Cancer, which was seen as an appropriate symbol for Christ, who was often depicted on the tympana below. According to Macrobius’s Commentary on the Dream of Scipio, during their incarnation, souls pass from the sign of Cancer into Leo, on their journey to Earth. Considering the popularity of this text throughout the Middle Ages, I argue that the notion of the ‘portal of men’, influenced the decision to provide the images of the crab and lion with conspicuous positions within sculptural programs of French portals. By considering these signs within the context of the surrounding decorative scheme, as well as providing relevant passages from contemporary theological texts, I aim to demonstrate how their depictions participated and contributed to the complex symbolism of church portals.

Descartes’in Epistemolojisinde Tanrı Fikri
Authors: KARAMAN Esra
Published: December 2020

Descartes, epistemolojisinde açık ve seçik bilginin elde edilmesinde şüphe yöntemini kullanarak düşünce tarihinde önemli bir yer edinmiştir. Duyular aracılığıyla elde edilen bilgiler başta olmak üzere sahip olunan bütün bilgileri şüphe süzgecinden geçirmiştir. Daha sonra, düşünme edimini esas alarak bilginin temel kaynağının zihin olduğunu ileri sürmüştür. Ontoloji ve epistemolojisini düşünme ediminden hareketle ve şüphe yöntemini kullanarak temellendirmiştir. Çalışmamızda ilk olarak Descartes’ın hakiki bilgiye ulaşmada nasıl bir yol izlediği, hangi ilkeleri benimsediği ele alınmıştır. İkinci aşamada, Descartes’ın bilgiden hareketle Tanrı fikrine geçişi incelenmiştir. Bu bağlamda, metafizik anlayışının temelleri, Tanrı’nın bilinebilirliği, Tanrı kanıtlaması, Tanrı fikrine neden ihtiyaç duyduğu vb. konular irdelenmiştir. Çalışmamızın amacı, Descartes’ın kesin ve sağlam kabul ettiği bilgi görüşü ile Tanrı fikri arasındaki ilişkinin nasıl olduğunu açıklamak, Tanrı’yı metafizik alana sıkıştırmayıp, epistemoloji ile bağıntısının anlaşılmasına dikkat çekmektir.
Müslüman Kimliğine Yönelen İki Tehdit: Deizm ve Sekülerizm
Authors: GÜNDOĞAR Hamdi
Published: December 2020

Deizm ve sekülerizmde aklın vahiy ve peygamberin yerine ikame edilmesi, ilahi dinlerin ve dolayısıyla İslam’ın vahiy ve nübüvvet müessesesi için bir tehdit, Müslüman kimliğini itibarsızlaştırmaya yönelik bir tehlikedir. Akla yüklenen bu misyon aynı zamanda ilahi dinlere ve İslam’a bir meydan okumadır. Dini konularda aklın yegâne kaynak kabul edilmesi dinin vahiy ve nübüvvetten arındırılması ve insana sınırsız, sorumsuz bir alan açılmasını sağlamaya yöneliktir. Bu çaba insanın dinin kural ve kaidelerinden bağımsız bir varlık haline getirilmesidir. Vahyin bildirimlerini bertaraf edip dini alanda da aklı egemen kılmaktır. Dini, ilahi din olmaktan çıkarıp, beşeri bir felsefe haline getirmektir. Dinin bireysel ve sosyal hayattaki yoğunluğunun azalması ve dünya merkezli düşünme ve yaşamayı ifade eden sekülerleşme, deistik bir inanca sahip olmanın, diğer taraftan Batılılaşmanın veya modernleşmenin doğal sonucu olarak ortaya çıkmaktadır. Sekülerleşme, sosyolojik veya psikolojik bir anlamı içermekte ve bu kavramla kişilerin toplumsal hayatlarında veya ferdi düşünce ve duygularında dinin etkin olma özelliğini kaybetmesi kastedilmektedir. Bu durumda itikadi alanda deizm, pratik hayatta sekülerizm Müslüman kimliği üzerinde olumsuz etki bırakan ve İslami yaşam biçimini tehdit eden önemli iki unsur olarak karşımızda durmaktadır.

Los sistemas de agua en el mundo son valorados por cada asentamiento humano ya que abastecen de agua para consumo, promueven la vida de los ecosistemas y permiten medidas de adaptación al cambio climático. En este contexto, el presente artículo tiene como objetivo mostrar la importancia de las albarradas en la Parroquia Valle de la Virgen y los servicios ecosistémicos que presta. Los métodos utilizados en la presente investigación fueron el método cuantitativo y descriptivo, que permitieron determinar un total de 31 albarradas distribuidas en toda la parroquia y en su conjunto poseen la capacidad de almacenar un aproximado de 4.738.063m3, de agua de lluvia que es la única fuente de agua en la zona durante la época de verano. Por otra, se debe indicar que entre los principales servicios ecosistémicos que brinda, está la dotación de agua para producción agrícola, abasto para pequeños ganaderos de la zona, y sirven como medio de vida para aves de tránsito. Por su parte el agua para consumo humano no es tratada, lo cual provoca la presencia de enfermedades gastrointestinales. Finalmente se debe indicar que los sistemas de agua existentes permitan la resiliencia de los habitantes y se adapten a la situación presente, que le vuelve comunidades sostenibles, quedando el reto por parte de los gobiernos territoriales de turno, promover un mejor desarrollo local con la dotación de servicios básicos, lo cual contribuye al cumplimiento de los objetivos de sostenibles y la agenda 2030.
ANÁLISIS DE OBLIGACIONES FISCALES ESTABLECIDAS PARA ASOCIACIONES DE ÁMBITO SOCIOECONÓMICO EN JIPIJAPA, MANABÍ
Authors: Proaño Ponce William Patricio , Alay Barcia Tamara Valeria
Published: December 2020

En la actualidad, cumplir con deberes tributarios se ha vuelto un derecho para toda sociedad. Sin embargo, muchas asociaciones de ámbito socioeconómico en Ecuador no se encuentran informadas en su totalidad sobre los derechos que corresponden como tal. Entre los factores están: desinformación, exigua cultura tributaria. Es por ello qué, es fundamental que los comerciantes conozcan sobre el cumplimiento de obligaciones fiscales. El problema abordado fue: cómo una metodología tributaria incide en la mejora de obligaciones fiscales en asociaciones de ámbito socioeconómico. Se determinó necesidades de información para acoger medidas que permitan visualizar herramientas que contribuyan al conocimiento y cumplimiento de tributos. La propuesta nace del diagnóstico sistemático a partir de una investigación basada en una sistematización bibliográfica de alta rigurosidad articulado con análisis bibliométrico, con el propósito de precisar elementos que connotan el paradigma estudiado. Asimismo, otros métodos adoptados fueron análisis documental, utilizado para la valoración de bibliografía relacionada con el problema; histórico lógico para establecer fundamentos asociados a la cultura tributaria; análisis y síntesis que proporcionó información con base más ajustada para abordar el problema científico; inductivo-deductivo que accedió al análisis de antecedentes particulares de los problemas existentes. Los resultados permitieron identificar la necesidad de desarrollar una propuesta metodológica que contribuya a la mejora de obligaciones fiscales en asociaciones de ámbito socioeconómico. Además, se logró determinar que el tema investigado no ha sido aprovechando en su totalidad en diferentes universidades de Ecuador, por lo qué, es evidente realizar propuestas enfocadas a la mejora de la cultura tributaria

Emotional burnout in medical workers during the work in extreme conditions
Authors: Pankov Vladimir A. , Lakhman Oleg A. , Kuleshova Marina V. , Rukavishnikov Viktor S.
Published: December 2020

Medical staff is exposed to a complex of adverse occupational factors of physical, chemical, and biological nature, high severity and intensity of the labor process. Unsatisfactory working conditions are associated with health risks for medical personnel and can lead to occupational and work-related diseases. The most often occupational diseases detected in medical staff are infectious ones. In the context of the spread of the new coronavirus infection (COVID-19), the probability of infection of the medical personnel themselves with possible damage to organs and body systems with a subsequent disability is high. The article pays considerable attention to the high level of neuro-emotional stress, the problem of burnout, accompanying the work of medical personnel, especially in extreme conditions, which include epidemics and pandemics, in particular the COVID-19 pandemic. The prevalence of burnout syndrome (BS) among medical personnel in many countries has reached crisis proportions, exceeding the level of any other occupational group. Despite a significant number of studies related to the study of BS in medical personnel, there are still difficulties with its diagnosis, primarily associated with the subjectivity of the methods used; there is little scientific evidence about the clinical manifestations of BS, its symptoms. The study of the phenomenon of emotional burnout, its prevention, treatment, and rehabilitation is relevant in connection with the direct relationship of BS not only to maintaining the health, mental stability, and professional longevity of specialists involved in long-term interpersonal communication but also to the preservation of the patients’ health. It is necessary to discuss making additions to the list of occupational diseases and to the list of harmful and dangerous industrial factors and works in which preliminary and periodic medical examinations are carried out, concerning medical staff whose working conditions are associated with the high nervous and emotional stress, in particular during work in extreme conditions.

Published: December 2020

The intensity of civil aircraft flights elevates with the increase in the number of passenger and cargo transportation by air. Aircraft noise in the residential area near airports grows up too despite the use of low-noise aircraft models by airlines. This causes an augmentation in the number of complaints of the population in these areas. The Russian Federation’s normative and methodological documents requirements in force relating to measurements and assessment of noise in residential areas, including «aircraft noise», were analyzed. Their requirements in terms of measuring and assessing noise in residential areas, including “aircraft noise”, testifies to the insufficiency and ambiguity of these requirements. The main disadvantages are the lack of a clear definition of which sound event is considered «aircraft noise» and the lack of requirements for the duration of the reference time interval of noise measurement. The foreign experience of measuring and evaluating aircraft noise, as well as the effects of such noise on the population, are considered. This made it possible to determine the necessary and sufficient parameters for noise control in residential areas, including «aircraft noise». There were proposed both a definition of «aircraft noise» and the necessary parameters for its assessment. The necessary duration of the reference time interval for the measurement of normalized parameters was justified. Method for the normalized noise parameters in residential areas measurement using the chronograms of sound levels A was proposed. The technical implementation of such a method is presented. Proposed a definition of «aircraft noise» and measuring normalized parameters in the 15-minute reference time interval for inclusion in regulatory and methodological documents will help to eliminate ambiguity in measurements and noise assessment in residential areas.

Published: December 2020

Introduction. For a comprehensive study of the urban environment, various natural objects, there were used - snow and soil cover, accumulating atmospheric precipitation, which allows assessing the spread of pollutants in the environment. The purpose of the study is to assess the quantitative content of priority pollutants in the snow/soil system as a result of dispersion from man-made sources. Material and methods. Studies of the content of polycyclic aromatic hydrocarbons (PAHs), petroleum products (PP), and fluorides in snow and soils under man-made loads were carried out. Snow sampling was performed at sites with undisturbed snow cover during the beginning of snowmelt. Soil samples were taken at the same points where snow samples were previously taken. Gas chromatography-mass spectrometry, fluorimetric and potentiometric methods were used. Results. The detected PP content in samples of snow/soil samples was in the range of 0.04-0.98 mg/l/2.8-71.2 mg/kg; Σ PAH -2.13-134.76 mg/l/0.13-38.987 mg/kg; fluoride- in the range of 0.68-13.48 mg/l/1.5-61.0 mg/kg. High concentrations of pollutants were registered at points closest to man-made sources, as well as near highways and railway tracks. The composition of PAHs is relatively uniform at all sampling sites. snow samples were mainly dominated by low-molecular polyarenes - from 52.8 to 68.5% of ΣPAH, and soil samples - 5 -, 6-nuclear PAHs, the proportion of which varied from 63.7 to 85.3% of ΣPAH. Conclusion. Analysis of the obtained material shows the maximum concentrations of pollutants (PAH, PP, Fluorides) to be observed for snow and soil samples near the industrial zone: 0.35 km South of the aluminum plant, as well as in a soil sample taken from the village of Olkha, at a distance of 2.5 km from the source.

Authors: Naumova Olga V. , Kudaeva Irina V. , Masnavieva Lyudmila B. , Dyakovich Olga A.
Published: December 2020

Introduction. Exposure to mercury and its compounds can be a risk factor for the development of cardiovascular diseases. The aim of the study is to investigate the levels of antibodies to oxidized LDL, intercellular adhesion molecules sICAM-1, sVCAM-1, and VEGF in individuals exposed to mercury. Material and Methods. A cross-sectional examination was carried out using biochemical methods in persons who have come into contact with metallic mercury with a work experience of more than five years, persons with a first established diagnosis of chronic mercury intoxication, and patients with chronic mercury intoxication in the long-term postexposure period. Results. In persons exposed to mercury with concomitant cardiovascular diseases, the level of sVCAM-1 differed depending on the presence/absence of intoxication and acquired maximum values in its long-term period, while the concentrations of sICAM-1 and antibodies to oxidized LDL did not differ significantly. In the groups without cardiovascular pathology exposed to mercury, the concentration of sVCAM-1 was higher in patients with intoxication, and sICAM-1 was 1.5-2 times lower when compared with experienced individuals, the level of antibodies to oxidized LDL was maximum in the presence of intoxication in its initial period. Discussion. The progression of chronic mercury intoxication is accompanied by an increase in the level of sVCAM-1, and a gradual decrease in the content of sICAM-1 to reference values. Trained workers were found to have elevated sICAM-1 levels. Conclusion. The role of antibodies to oxidized LDL, intercellular adhesion molecules is their multidirectional participation in the mechanisms that inhibit or contribute to the formation of cardiovascular pathology in individuals exposed to mercury.

Published: December 2020

Introduction. Currently, the role of neurochemical factors in the pathogenesis of disorders caused by mercury exposure remains unclear. Material and methods. A survey was conducted of 77 male patients (average age: 45.4+1.1 years, average experience - 17.1+1.1 years) exposed to mercury vapor (46 persons without pathology, 31 - with signs of disorders in the nervous system), 36 patients were diagnosed with chronic mercury intoxication (CMI) in the long-term period. We determined dopamine (DA), noradrenaline (NA), epinephrine (AD), normetanephrine (NMN), metanephrine (MN), serotonin (SER), histamine (HIST), brain neurotrophic factor (BDNF), neurotrophic factor 3 (NT-3), ciliary neurotrophic factor (CNTF), and neuron-specific enolase. The analysis of features correlations was calculated by the sum of the square of correlation relations (∑ŋ) between indices and the determination of the influence and dependence ranks for each component. Results. In workers without signs of pathology, the leading role among catecholamines was occupied by NA (∑ŋЗ/NA = 1.65), in the general system the top position belonged to HIST (∑ŋЗ/HIST = 2.10), SER had a minimum value (∑ŋЗ/SER = 0). In individuals with signs of disorders in the nervous system, AD and DA were regulated via NMN (ŋAD/NMN = 0.29) and MN (ŋAD/MN = 0.59 and ηDA/MN = 0.46), which had an upper position in the system (∑ŋЗ/NMN = 1.62 and ∑ηЗ/MN = 1.92). CNTF belonged to the determining position among neurotrophic factors (∑ŋЗ/CNTF = 0.75). In patients with CMI, NA (∑ŋЗ/NA = 1.48) was the leading position. SER and HIST occupied the lowest ranking position (∑ŋЗ/SER = 0.59 and ∑ŋЗ/HIST = 0.25). The presence of three closed subsystems is established. In one of them (NT-3, CNTF, and BDNF), BDNF was influenced by other factors. Discussion. The interdependence between neurochemical indices specifyie their involvement in the pathological process of disorders in the central nervous system under chronic mercury exposure. Conclusion. Changes in the interdependencies in the system of neurochemical indices under the influence of mercury have a labile character, which determines the development of clinical manifestations of the disorders of the nervous system.
Copper distribution in organs and tissues of albino rats under oral administration of nanocomposite of copper oxide encapsulated in a polymeric matrix of arabinogalactan
Authors: Lisetskaya Lyudmila G. , Titov Evgeny A.
Published: December 2020

Introduction. Based on arabinogalactan, a complex of hybrid nanobiocomposites has been created, which carry a balanced amount of macro- and microelements necessary for the body. A feature of the action of nanoparticles on the body is their ability to easily penetrate all organs and tissues. The aim of the work is to study the effect of copper arabinogalactan on the content of copper in the main tissues and organs of rats. Material and methods. The content of copper in organs and tissues of rats after a 10-day intragastric administration of a solution of copper arabinogalactan in a dose of 500 μg per kg of weight was studied by the atomic absorption method. Results. A high level of copper (above 2 μg/g) was found in wool, kidneys, liver, and heart. The brain and testes contain from 1 to 2 μg/g of copper. In the tissues of the stomach, small and large intestines, thymus, pancreas, blood, eyes, spleen, lungs, and skeletal muscles - less than 1 μg/g. Conclusion. The study of the distribution of copper in the organs of rats after oral administration of the nanocomposite of copper oxide with arabinogalactan demonstrated the main target organs for the accumulation of the element to be the kidneys, liver, brain, and stomach. The different character of the accumulation of copper in the tissues of the body of the rats received arabinogalactan of copper in the form of a nanocomposite, may indicate the selective ability of tissues and organs to accumulate this element. For further work on the possible use of the drug for medicinal purposes, it is necessary to take into account the peculiarities of biodistribution and bioaccumulation in various organs.

This study aimed to determine the lethal concentration (LC50) of Terminalia catappa leaves extract on three cyprinid species; carp (Cyprinus carpio), goldfish (Carassius auratus) and tiger barb (Puntigrus tetrazona) through the acute toxicity test. The leaves of T. catappa were extracted with methanol and prepared in various immersion concentrations (40, 80, 100, 150, 200, 250, 300, and 350 mg/L). These extracts were immersed in the aquarium and left for 24 h before performing the acute toxicity test. The water quality was also analyzed before and after adding the extract immersions into the aquarium. The acute toxicity test conducted for 96 h with 10 fishes of each cyprinid species (4.0-6.0 cm length) in 30 L water capacity aquarium. The mortality of each cyprinid species was recorded at 24 h time interval and LC50 of the extracts throughout 96 hours was determined through the probit analysis application. Specifically, the LC50 of T. catappa leaves extract were 349.89, 338.65 and 318.48 mg/L exhibited for carp, goldfish and tiger barb, respectively. A high concentration range of any plant-based extract has the potential to become toxic to particular fishes. Thus, it is an effort from this study to identify the safety margin of T. catappa leaves extract before its therapeutic values can be further manipulated and elucidated in aquaculture research.

Published: December 2020

Pepper (Piper nigrum L.) is one of the most important cash crops in Sarawak. The productivity of pepper is consistently low due to the low yield of berry production. One of the major problems of pepper production is inconsistent flowering time. This is due to the morphology and inheritance of functional male, female and hermaphrodite (bisexual) flower in P. nigrum which affect the productivity of pepper. For the exploitation of pepper for its maximum production, the detailed of flower development and flower composition are important factors to be considered. A field survey was conducted to determine the status of farming practices and problems encountered by the farmers. The study was also done to determine the composition of flower which influenced the consistency of berry production in P. nigrum in Sarawak. Surveys were conducted at 18 pepper farms in Sarawak to determine the composition of flowers in different types of Sarawak pepper varieties which are Kuching, Semenggok Aman and Semenggok Emas. Nine spikes were harvested in each pepper vine. Three pepper vines were selected randomly for each variety. The spikes were then observed under 3D Keyence microscope to determine the number of flowers of each type of flower. The survey on the farming practices were also conducted. The composition of flower was found to be varied between varieties. ‘Kuching’ variety had less hermaphrodite flower when compared to ‘Semenggok Aman’ and ‘Semenggok Emas’ varieties. In addition, a proportion of 29% farmers had encountered root rot disease problem in their farm, while 21% stated that unsynchronisation of berries production in each harvesting time as a major problem.

Published: December 2020

Liberica coffee is a minor species that is planted all around the world. Therefore, there is little study conducted on this coffee species as only one percent is cultivated all around the world. In Malaysia, there is still no research focusing on coffee pulp from Sarawak liberica sp. and thus leading to this study. The wastes and by-product such as coffee pulps will become the residues as they were not needed in processing the coffee. This will create environmental pollution. Thus, this research aimed to evaluate the feasibility study on the physicochemical properties of coffee pulp from Sarawak liberica sp. including determination by colorimetric assays for phenolic and flavonoid content, antioxidant activity, and reducing sugar analysis. The antibacterial activities of coffee pulp were evaluated against Gram-positive, Staphylococcus aureus, and Gram-negative Salmonella typhimurium using a disc diffusion method. As a result, Sarawak liberica sp. coffee pulp extract contained total phenolic content of 24.24 mg GAE/g of coffee pulp, a total flavonoid content of 39.39 mg QE/g of coffee pulp, DPPH scavenging activity of 92.24 ± 0.03%, reducing sugar analysis of 13.13 mg GE/g of coffee pulp, and there was no significant effect of antibacterial activities. Therefore, the physicochemical study determination in this study would add values toward Sarawak liberica sp. coffee pulp by-product and thus reducing the disposal of Liberica coffee wastes in the future.

Invasive introduced fish species are well known for their deleterious impacts on aquatic biodiversity and environment. This study provides the first report on the occurrence of introduced Amazon sailfin catfish, Pterygoplichthys pardalis from the Gombak basin, Selangor, Malaysia, where the suckermouth catfish, Hypostomus plecostomus and vermiculated sailfin catfish, Pterygoplichthys disjunctivus had been previously reported. Besides, selected morphometric and meristic measurements between P. pardalis and P. disjunctivus from the Pusu River, Gombak basin were compared. Moreover, we also described two body patterns of the P. pardalis collected from the river. The body pattern which does not fit entirely with the known characteristics of P. pardalis or P. disjunctivus is suspected to be a result of hybridization between both species, but deeper study should be conducted to confirm this claim.

Published: December 2020

The composition of the material and its processing conditions effect the microstructure of that material. Mechanical properties are inturn dependent on the material's microstructure. Thus the study of microstructure is important to asses the material processing conditions. This also helps in forensic analysis of material failure. Metallography deals with the material microstructure study. Classification of Material is the first step of the metallographic analysis. The tonal distribution of the microstructural image is completly dependent on the material and its composition. The current paper proposes a automated technique for classification of materials using image processing algorithms.
