Published: June 2021

In this study, highly accurate measurements of density and dynamic viscosities of a recombined live oil and its mixture with additional CO2were performed. The experiments were carried out under pressure and temperature gradients found in Brazilian Pre-salt reservoirs, that is, in the pressure range from (27.6 to 68.9) MPa and at (333.15 and 353.15) K. The assumption of volume change on mixing is evaluated from the experimental results, and the influence of pressure and temperature on the volume change upon mixing is assessed. The densities of mixtures are calculated considering (i) the excess volume approach, and (ii) no volume change. The densities are better correlated using the excess volume approach with Average Absolute Deviations (AAD) of 0.03%. Thirteen mixing rules of viscosity are examined by comparing the predicted values with the experimental viscosity of the recombined live oil + CO2mixture. The performance of some rules using compositional fractions (molar, volume and weight) is also evaluated. Thus, a total of 28 different ways to calculate the mixture viscosities were tested in this study. The worst result was obtained with Bingham’s method, leading to 148.6% AAD. The best result was obtained from Lederer’s method with 2% AAD and a maximum deviation of 5.8% using volume fractions and the fitting parameterα. In addition, deviations presented by the predictive methods of Chevron, Double log, and Kendall did not exceed 9% AAD, using weight fractions (Chevron and Double log) and molar fractions (Kendall and Monroe).

Published: June 2021

Based on the physical model of the Ranque effect, proposed earlier, a simplified mathematical model of the working process of a vortex tube is compiled taking into account the exchange of work and heat during the interaction of peripheral and axial gas flows. The effect of viscosity and angular velocity gradient on the transfer of kinetic energy from the axis to the periphery is shown. The difference in thermodynamic temperatures when heat is supplied from the periphery to the axis is taken into account, which leads to a decrease in the cooling efficiency of the axial gas flow. Energy exchange is based on the assumption that the peripheral gas layers are compressed by the axial flow. The axial flow work is determined by the pressure difference between the valve and the outlet of the diaphragm

A TOTALIDADE ÉPICA EM VIVA O POVO BRASILEIRO: PARA UMA AUTÊNTICA HISTÓRIA DO BRASIL
Authors: Oliveira Sara Lelis de , Abreu Juliana Marafon Pereira de , Lima Júnior Walter Guarnier de
Published: June 2021

O presente trabalho consiste em apresentar a obra literária Viva o Povo Brasileiro (1984), do escritor João Ubaldo Ribeiro, como uma narrativa que responde ao gênero literário postulado por György Lukács que retrata a totalidade da história: o romance histórico. Segundo o filósofo húngaro, a possibilidade de narrar a totalidade histórica na literatura moderna origina-se de uma perspectiva filosófico-literária que tende para a épica e pensa o indivíduo em seu tempo a partir de uma articulação entre passado e presente. Esse movimento, dialético em si mesmo, propicia uma narração autêntica da história, isto é, que não negligencia acontecimentos essenciais na história de uma nação. É o caso de Viva o Povo Brasileiro e a narração de nosso passado entre os anos 1647 e 1977, na qual se rememoram acontecimentos históricos que preenchem as lacunas da historiografia oficial brasileira, provocando uma consciência histórica na contramão das narrativas historiográficas dominantes.
PALAVRAS E IMAGENS EM UM UNIVERSO DUPLICADO: UMA REPRESENTAÇÃO IMAGÉTICA DE 1Q84, DE HARUKI MURAKAMI

Published: June 2021

Este artigo analisa algumas possibilidades de interpretação da obra 1Q84, de Haruki Murakami, utilizando-se o procedimento de investigação e descrições imagéticas como experiências literárias, discutindo, a partir dos três tomos que compõem a obra, as relações entre linguagem escrita e imagens produzidas pelo leitor. Trabalha-se, sobretudo, a noção de cartografia de imagens, a intertextualidade que a produção de imagens proporciona ao descrever o devir-imagem na literatura. Como aporte teórico, utiliza-se as reflexões de autores como Maurice Blanchot, Georges Didi-Huberman, Michel Foucault e Roland Barthes, entre outros.
O BATISMO MÍNIMO: MORTE E POESIA EM HILDA HILST
Authors: Luz Cleber da Silva , Silva Sandro Adriano da
Published: June 2021

Para Octavio Paz (2012), a poesia evoca uma materialização do sentir, do falar e do viver, nutrida que é pela angústia, tensionada pela ausência e, portanto, própria Ã  interrogação sobre a experiência da perda, da transcendência, da efemeridade, e, no limite, da morte. Pautando-nos em conceitos e em elementos constitutivos do gênero lírico (MOISÉS, 2012); na concepção de poesia e poema (PAZ, 1982); na projeção da forma arquitetônica (BAKHTIN, 1998); na natureza da lírica como criadora de complexos de imagens dotados de pathos (CROCE, 2011), tencionamos apresentar uma análise interpretativa do poema intitulado “XXIII”, que integra a obra Da Morte. Odes Mínimas (2003), de Hilda Hilst, identificando os efeitos de sentidos produzidos, a perspectiva, o tom e suas relações com o tema, a partir dos recursos estilísticos presentes no poema. Explorando, principalmente, as metáforas do batismo e da morte. Metáforas responsáveis pela expressão das emoções subjetivas, das condições da alma e do pensamento, dos sentimentos mais profundos do eu lírico, poeticamente elencados e “batizados” por Hilda Hilst.
ECOS DA MINHA ALMA CRIVADA DE RAÇAS
Authors: Andrade Caroline Neres
Published: June 2021

O trabalho tem como objeto de estudo o poema Improviso do Mal da América (Fevereiro de 1928), de Mário de Andrade. Diante desse poema abordaremos a questão da construção da identidade brasileira. O poema apresenta essa busca fatigada por uma identidade não apenas do eu-lírico e de São Paulo, mas do Brasil como um todo. Neste trabalho abordaremos a construção poética numa perspectiva de conexões e contradições que emergem as relações de diversos povos, falas e cores. O eu-lírico no poema aponta a complexidade do fazer poético em torno da mistura e apagamento não apenas de povos dispostos no poema, mas da própria linguagem diversa na composição estética da condução imagética da historicidade que emerge o ser social. O poema será analisado de acordo com o embasamento teórico de João Luiz Lafetá e György Lukács que elucidarão questões referentes a estrutura narrativa que tem como projeto estético humanizador em sua potência transformadora e crítica.

O MÉTODO DA AIA COMO PROCEDIMENTO: SINAIS DE UM PARADIGMA INDICIÁRIO E DE UMA ESCRITA ASSASSINA NO ROMANCE MEU NOME É VERMELHO
Authors: De Sales Jucelino
Published: June 2021

O artigo discute o método da aia submerso na diegese do romance Meu nome é vermelho do escritor Orhan Pamuk, e sua relação com o paradigma indiciário abordado pelo historiador Carlo Ginzburg em sua obra histórica. Abordamos como esse método auxilia na revelação da identidade do assassino nos interstícios desse romance, a partir dos sinais, vestígios e rastros deixados na diegese pelo autor dos dois crimes: a morte do miniaturista Elegante Efêndi e do Tio Efêndi. Empenhamos em demonstrar também, como a partir desse método, é possível uma leitura sobre o funcionamento formal dessa obra. Trabalhamos com a seguinte hipótese: a inserção de um estilo historiográfico que faz parte da prática metódica da escrita da história na diegese do romance apresenta-se como uma ironia moderna e como perspicácia do escritor para indicar ao leitor (semiótico) uma maneira dele se aproximar daquele lugar em que a escritura romanesca deposita a sua forma: o discurso narrativo. Abordaremos ainda o que estamos chamando de escrita assassina, a partir das leituras de Roland Barthes e Maurice Blanchot, que argumentam que o escritor escreve para morrer em sua obra, e assim validar sua permanência na memória de literatura.
REFLEXÕES SOBRE CONJUGALIDADE E MATERNIDADE NO CONTO A IMITAÇÃO DA ROSA, DE CLARICE LISPECTOR
Authors: Freire Pollianna de Fátima Santos
Published: June 2021

Considerando-se que, na nossa sociedade, o “casamento e a maternidade como seu corolário aparecem […] como o locusideal do feminino” (NAVARRO-SWAIN, 2007, p. 210) e, na ordem do sistema patriarcal, “a capacidade específica de procriação do feminino torna-se o próprio feminino […] cuja existência se justifica pela sua capacidade de reprodução” (NAVARRO-SWAIN, 2007, p. 220-221), analisarei o conto “A imitação da rosa”, presente em Laços de Família(1960), a fim de discutir sobre dispositivos do sistema sexo/gênero que, ao longo dos séculos, vêm operando como mecanismos de opressão das mulheres. Entendendo que o principal discurso simbólico do sistema representacional do patriarcado presente neste conto está relacionado Ã  incapacidade de procriação de Laura e, consequentemente, ao não exercício da maternidade, pretende-se discutir, a partir de uma visão teórica foucaltiana, sobre as estratégias adotadas pela personagem para resistir a esses mecanismos de opressão bem como discutir, ainda, em que medida o espaço heterotópico é explorado nessa narrativa como estratégia de resistência.

Synthesis, crystal structure, and properties of heteroleptic Cu(I) dithiocarbamate complex containing diphenyl phosphinoferrocene (dppf)
Authors: Kumar V. , Singh S.
Published: June 2021

A new copper(I) heteroleptic pyridyl functionalized dithiocarbamate (dtc) complex, [Cu(L)2dppf]·2H2O·MeOH, (1) (where L = N-benzyl-N-methylpyridyl (dtc) and dppf = diphenyl phosphinoferrocene), has been synthesized from the reaction of [Cu2(μ-Br)2(k2-P,P-dppf)2] and dithiocarbamate ligand (L). The synthesized complex has been characterized by elemental analysis, spectroscopy techniques (IR, 1H, 13C, 31P NMR, and UV-Vis), and single-crystal X-ray crystallography. In this heteroleptic complex, the Cu atom forms distorted tetrahedral coordination geometry. The supramolecular architecture in the complex has been sustained in the solid phase by, C—H⋯O and C—H⋯π (chelate = CuS2C) interactions. The emission spectrum of the complex has been studied in DCM solution. The charge-transfer excited state is quenched due to intramolecular energy transfer from the {Cu(S,S)(P,P)} moiety to the ferrocene therefore dppf-based complex shows no detectable emission at room temperature. This complex is weakly conducting and exhibit semiconductor behavior at room temperature.
Judgement in geotechnical engineering practice
Authors: Brito José António Mateus de
Published: June 2021

Professional judgement is the basis for many of the decisions taken by geotechnical engineers to make progress in the design, execution and works supervision. Judgment is a mandatory component of any engineering achievement, essential to assess the various uncertainties that inevitably affect engineering practice. Confidence in such judgements can result in small to big consequences, not only for the engineer itself, but also for others, sometimes with the risk of human loss and significant damage. The definition and the development of judgment in geotechnical engineering is discussed. The bases of the judgement are analysed in detail and the heuristics and bias, responsible for failures in the judgment, are identified. The importance of experts’ judgement and codification are highlighted and ways to improve judgment are also described. The lessons learned in a case study of one accident and two incidents that have occurred during the execution of the Lisbon Terreiro do Paço metro station construction works are presented to highlight the importance of an informed decision making informed through the engineering judgement.
New Trends In Treacher Collins Syndrome: Bony Reconstruction And Regenerative Therapy
Authors:   1Unit of Maxillo-Facial Surgery, Istituto Stomatologico Italiano, Via Pace, 21, 20122 Milano, Italy,   2 Department of Biomedical Sciences, University of Padova, 35100 Padova, Italy
Published: June 2021

Aim:Treacher Collins syndrome is a rare congenital disorder of craniofacial development with a highly variable pheonotype. This syndrome occurs with an incidence of 1:50,000, and more than 60% of the cases have no previous family history and arise as the result of de novo mutations. The disorder displays an intricate underlying dysmorphology. Affected patients may suffer life-threatening airway complications and functional difficulties involving sight, hearing, speech, and feeding. Deformation of facial structures produces a characteristic appearance that includes malar-zygomatic hypoplasia, periorbital soft tissue anomalies, maxillomandibular hypoplasia, and ear anomalies. Management requires a specialized craniofacial team, as comprehensive care starts at birth and may require life-long follow-up. Standard craniofacial procedures for bony and soft tissue reconstruction are used. This article outlines current treatment strategies and future concepts for surgical and regenerative management. Methods:The new field of regenerative medicine and therapy offers the promise to improve some of these treatments. In particular, Structural Fat Grafting (lipostructure) seems to be a good strategy to restore the normal volume and contour of the face, and to provide a source of adipose-derived stem cells (ADSCs) with a multilineage differentiation potential. In this work, we present the case of a young girl with Treacher Collins Syndrome who underwent serial sessions of fat grafting in addition to other surgical bony reconstructive techniques. ADSCs have been isolated from the patient’s lipoaspirate, and compared for their stemness properties with those of a healthy subject. Conclusion:Screening of the genome of the Treacher Collins patient using array-Comparative Genomic Hybridization (array-CGH) allowed us to identify some chromosomal imbalances that are probably associated with the syndrome.Correction of these imbalances and asymmetries by modulating ADSCs could be an innovative approach to improve and stabilize the results of the surgical treatment of Treacher Collin Syndrome.

Published: June 2021

El biocarbón es el producto resultante de la transformación termoquímica de la biomasa vegetal por pirólisis. Sirve como enmienda en suelos y presenta beneficios en la producción agrícola. El objetivo del presente estudio fue evaluar el efecto del biocarbón en el rendimiento y la respuesta de variables agronómicas de un maíz comercial en Maravatío, Michoacán. El biocarbón se obtuvo de biomasa seca de olotes de maíz usando un reactor de pirólisis. Se aplicó en suelos arcillosos biocarbón finamente triturado a tasas de 1% (T1), 2% (T2) y un control 0% (T0). Las dosis fueron calculadas con base en el peso del suelo de la capa arable (10 cm). La dosis de fertilización fue 200N-80P-150K-30S para los tratamientos y el control. El diseño fue en bloques al azar con cuatro repeticiones de 9 m2 cada una. La comparación de medias se realizó con la técnica de Tukey-Kramer. Los resultados indican un incremento en el rendimiento de 1.2 Mg ha-1 (T1) y 1 Mg ha-1 (T2), con respecto al control (T0). El peso de la mazorca, de grano por planta, olote y longitud de mazorca, presentaron la siguiente tendencia, T1 > T2 > T0. El diámetro de tallo y peso seco de la planta fue mayor en T1. La altura de la planta y diámetro de tallo fue mayor en T2. La profundidad de raíz no presentó diferencias significativas entre los tratamientos; sin embargo, la tendencia en el desarrollo lateral de raíces fue T2 > T1 > T0 que sugiere un efecto positivo para el desarrollo y exploración de la raíz que podría explicar el incremento en el rendimiento. Se concluye que el biocarbón es una alternativa viable para aumentar la producción de maíz y favorece el desarrollo vegetativo de la planta en la región Oriente del estado de Michoacán.
The Predatory Journal: Victimizer or Victim?
Authors: Gill Grandon
Published: June 2021

Aim/Purpose: Labeling a journal as “predatory” can do great damage to the journal and the individuals that have contributed to it. This paper considers whether the predatory classification has outlived its usefulness and what might replace it.

Background: With the advent of open access publishing, the term “predatory” has increasingly been used to identify academic journals, conferences, and publishers whose practices are driven by profit or self-interest rather than the advancement of science. Absent clear standards for determining what is predatory and what is not, concerns have been raised about the misuse of the label.

Methodology: Mixed methods: A brief review of the literature, some illustrative case studies, and conceptual analysis.

Contribution: The paper provides recommendations for reducing the impact of illegitimate journals.

Findings: Current predatory classifications are being assigned with little or no systematic research and virtually no accountability. The predatory/not predatory distinction does not accommodate alternative journal missions.

Recommendations for Researchers: The distinction between legitimate and illegitimate journals requires consideration of each journal’s mission. To serve as a useful guide, a process akin to that used for accrediting institutions needs to be put in place.

Impact on Society: Avoiding unnecessary damage to the careers of researchers starting out.

Future Research: Refining the initial classification scheme proposed in the paper.

Çeviride zaman kavramı bağlamında tarihselleştirme ve modernleştirme yöntemleri üzerine bir değerlendirme: Balzac’ın Çalışanın Fizyolojisi’nin Türkçeye Çevirisi Örneği
Authors: ÖZCAN Onur
Published: June 2021

Çeviri eylemi kendi içerisinde birçok değişkene sahip olsa da, “zaman” kavramı bu değişkenler arasında kaynak metnin ve hedef metnin kaleme alındığı dönemlerin temsil dili bakımından ön plana çıkmaktadır. Bu yüzden kaynak metnin tarihin hangi döneminde yazıldığı kadar, çeviri metin olan hedef metnin ne zaman basıldığı da önemlidir. Özellikle zaman dilimi olarak arasında büyük farklar bulunan metinlerde, çevirmen çeviri sürecinin gerektirdiği tarihsel ve güncel özellikleri hedef metne yansıtabilmek için geçmiş (eserin yazıldığı dönem) ve şimdi (eserin çevrildiği dönem) olmak üzere tarihin iki noktasında adeta mekik dokumaktadır. Çevirmen bunu yaparken kaynak metnin yazıldığı döneme yönelirse tarihselleştirme ve kaynak metnin çevrildiği modern zamana yönelirse modernleştirme şeklinde iki yönteme başvurmaktadır. Dolayısıyla bu çalışma Popoviç, Holmes ve Nida’nın doğrudan ya da dolaylı olarak önerdiği bu iki yöntemin uygulamalı olarak daha iyi anlaşılmasını ve özellikle kaynak ve hedef metninin arasında zamansal olarak büyük fark olan bir eser çerçevesinde bu iki yöntemin incelenmesini amaçlamaktadır. Bu bağlamda Balzac’ın 19. yüzyılın ilk yarısındaki Fransız devlet yönetimini ve bürokrasisini ele aldığı bir deneme eser olan ve ilk olarak 1841’de yayımlanan Physiologie de l’Émployé’nin yaklaşık 180 yıl sonra Çalışanın Fizyolojisi olarak Türkçeye çevirisi bu çalışmanın örneklemi olarak seçilmiştir. Çeviride zamandan kaynaklı farklılıkları gidermek için çevirmene çeviri sürecinde yardımcı olan bu iki yöntemin böylesine bir zaman farkına sahip iki metin çerçevesinde incelemenin çeviri pratiği anlamında hem çevirmenlere hem de çevirmen adaylarına katkı sağlayacağı düşünülmektedir.

Governmental policies that promote biofuels such as biodiesel have led to the generation a largeamounts of glycerol waste as a low-cost raw material. The purpose of this paper is to present a technoeconomic study on the production of biomass-based propylene glycol via glycerol hydrogenolysis,considering hydrogen feeds that partially or fully utilize renewable sources. For analysis andcalculation, computer simulations are carried out using the Aspen Hysys V11 simulator. The technoeconomic analysis is performed by modelling the propylene glycol synthesis process from glycerol,which is then used to calculate the facility capital cost and estimate operating costs to obtain an annualreturn on investment. Sensitivity analysis is also conducted for several parameters on a 36,000ton/year propylene glycol plant. The results showed the production cost was 0.76 USD/kg or 10,802IDR/kg when the hydrogen is generated from the natural gas steam-methane reforming (SMR)process. If the hydrogen is produced from the glycerol steam reforming process, which is fullyrenewable, the plant is not feasible, as indicated by a negative net present value (NPV).

Sei Pagar's palm oil mill (PKS Sei Pagar), PTPN V Riau processes fresh fruit bunch into crude palm oil(CPO). This processing also generates waste like empty fruit bunches (EFB), shells, fiber, and palm oilmill effluent (POME). POME has a high content of chemical oxygen demand (COD), approximately30,000-80,000 mg/L, which is usually fermented by bacteria. This fermentation mechanism can beused to produce biogas containing methane in a continuous stirred tank reactor (CSTR). Since POMEor organic materials for biogas production generally contain sludge, the biogas production processshould have an agitator to mix sediment in the base reactor and improve biogas production. Thisresearch aims to determine the agitator's specifications for the biogas pilot plant in PKS Sei Pagar,consisting of power type and type of stirrer include diameter calculation, geometry, and powercalculation. The agitator's power and geometry are determined based on input data from the datasheetreactor and the efficiency of the stirrer is calculated by Reynolds reynolds numbers. From thisresearch's calculations, an agitator geometry for the biogas pilot plant in PKS Sei Pagar had a length of0.875 m, a width of 0.7 m, and a height of 3.5 m. This research also obtained that the motor power resultwas 23.55 HP. The selection of motor power in the Biogas pilot plant's stirring process in PKS Sei Pagarshould have a standard agitator motor power of 25 HP.

Renewable energy development for power generation is in line with the government's program toincrease the share of renewable energy in the national energy mix which is relatively small at themoment. BPPT, collaborating with PTPN 5 in the Insinas Flagship program, built a pilot plant for biogasproduction from Palm Oil Mill Effluent (POME) with a capacity of 700 kW. The reactor used in this pilotproject is a Continuous Stirred Tank Reactor (CSTR) which is the most important operating unit forproducing biogas from POME. Therefore, the selection of the CSTR foundation is crucial since themain process occurs in the reactor. The scope of this activity is to realize the final design into theconstruction of a CSTR pilot plant. Several types of foundations were studied, starting from shallowfoundation type such as tread foundation, deep foundation, until combining shallow foundation typewith deep foundation type. The evaluation of existing data and design review indicates that the use ofMat Foundation is not suitable due to soil condition at a depth of 0–5m which is in the form of sandyloam soil with an NSPT value of less than 20. The selection of Piles is based on the calculations usingtotal vertical load of 3035,37 ton and total horizontal load of 542,57 tons. Considering the availability ofmaterials and time concern, the recommended foundation type is pile with a diameter of 600 mm typeB and a length of 12 m.

This study was designed to examine the effects of the Delta-Songhai agricultural programs on beneficiaries in Delta State. Some objectives of the study were to: ascertain the type of training, determine the income generation level of the participants, measure the level of empowerment, and measure the level of satisfaction. A sample size of 72 was used in the study. This was obtained from random sampling using a multistage procedure. Results obtained were that male respondents (62.5%) dominated more than female with a mean age of 32 years. Respondents’ average farming experience was five years. Respondents (97.2%) adopted poultry records skills, while respondents (94.5%) adopted aquaculture concrete pond techniques. Respondents were greatly empowered by the training program with a pooled mean of 2.89. Respondents’ satisfaction level was high with a pooled mean of 2.89. Some constraints faced by the respondents were mostly, insufficient funds from the donor, poor project monitoring, and beneficiaries nonchalant behaviour after programme completion. Correlation result between poultry and aquaculture on income generation showed that poultry was more favourable than aquaculture. The study concluded that the training programme had a great impact on youth empowerment in poultry, aquaculture, piggery, and grass cutter production. It was recommended that these positive impacts should be sustained.

The investigation was carried out on slightly leached chernozem soil type during 2014 – 2016. The effects of different soil tillage methods for sunflower on the vertical distribution of the seeds in the soil layer and the development of the plants were followed – ploughing at 24-26 cm, chisel ploughing at 24-26 cm, disking with disk harrow at 10-12 cm and no-tillage. The highest percent of sunflower seeds in the zone of the soil layer optimal for sowing (5-7 cm) were significantly placed in the areas cultivated with chisel-ploughing (62.1%). Under the other types of soil tillage, their amount decreased. When sowing was performed at a mean diurnal air temperature close to the norm (10.1 °С), the emergence of the plants in the variants with chisel ploughing, disking and no-tillage occurred significantly slower in comparison to ploughing. At higher mean diurnal air temperature (12.0 °С), only at the beginning of sunflower emergence some delay was observed depending on the type of the applied soil tillage. Under these conditions, a significant difference in the occurrence of the phenophases was determined in the variants with disking and direct sowing, as compared to the areas with ploughing. With the minimizing and exclusion of the soil tillage, the growth of the sunflower plants was significantly retarded at the initial stages of their development. At phenophase flowering, the plant height and the stem diameter were lowest in the areas cultivated with disking. The investigated types of soil tillage did not have a significant effect on the diameter of the sunflower heads.

Çalışmada Türkiye doğal florasında yetişen Apiaceae familyasına ait 12 farklı bitki türünün uçucu yağının Kök lezyon nematodlarına (Pratylenchus penetrans, P. thornei ve P. neglectus) karşı nematisidal etkileri incelenmiştir. Araştırma in vitro koşullarda yürütülmüş olup, her bir uçucu yağın 1000 ppm konsantrasyonu kullanılmıştır. Uçucu yağların nematisidal etkileri Kök lezyon nematodu türüne bağlı olarak değişiklik göstermiş, P. neglectus türünde Coriondrum sativum L., P. thornei türünde Ferulago cassia Boiss, P. penetrans türünde ise Foeniculum vulgare Miller ve Anethum graveolens L. uçucu yağları diğer uygulamalardan daha yüksek etkinlik göstermiştir. Uçucu yağ uygulamalarına bağlı olarak gerçekleşen nematod ölüm oranları P. neglectus türünde % 24.3-64.7, P. penetrans türünde % 23.7-66.7 ve P. thornei türünde % 33.7-85.0 arasında bulunmuştur. Araştırmada, uçucu yağ aktif maddelerinden linalool, phallendrene ve 2,3,6 trimetilbenzaldehyde bileşenlerini içeren bitkilerin yüksek, anethole ve carvone bileşenlerini içeren bitkilerin orta, caratol ve curzerene bileşenlerini içerenlerin ise düşük nematoksik aktivite gösterdiği anlaşılmıştır. Apiaceae familyası türlerinin Pratylenchus türlerine karşı nematisidal etkilerinin yüksek fakat değişken olduğu, bu nedenle yüksek aktivite gösteren uçucu yağların farklı dozlar kullanılarak arazi koşullarında etkinliklerinin denenmesi ile daha kesin sonuçlara ulaşılabileceği anlaşılmıştır.

The aim of this research is to evaluate and analyze the influence of different degrees of salt stress on the tolerance of Australian wheat lines having characteristics derived from wild types in comparison with a local cultivar well–adapted to Anatolian conditions under controlled conditions. In the research, the two lines, namely AU5924 and AU5907, adapted to Australian conditions harbor HKT1;4 and HKT1;5 loci and Bayraktar 2000 cultivar used as genetic material. In our study, a trial plan with four replicates and two salt treatment doses (0 mM control group and 200 mM stress group) was designed. The samples were collected for elemental analysis, measuring physiological parameters as well as determining proline content after the appearance of stress symptoms. In this respect, (K), known to play an important role in enhancing stress tolerance, was found to be higher in HKT–containing lines in comparison to Bayraktar 2000. HKT genes could improve the production of Anatolian varieties. While the dry weight of the genotype Bayraktar 2000 was higher than the lines checked, the proline content of line 5907 was lower and the potassium and (K/Na) ratio decreased. These parameters effectively increased the dry weight under salt stress. However, the line 5907 demonstrated the best tolerance among all analyzed genotypes.

The purpose of this experiment was to define the influence of different doses of calcium chloride (CaCl2) applications on fruit yield, some quality properties, and nutrition of plant in Hicaznar pomegranate cultivar during 2016 and 2017 in Aydın (Turkey) ecological condition. In the study, 0.2, 0.4, 0.6, 0.8, and 1.0% solutions of calcium chloride (CaCl2) were applied by spraying except the control dose to the trees. The solution doses were twice applied during the fruit growing season in June and August. According to the results, fruit yield, peel thickness, fruit length, diameter, and weights were increased compared to control dose with CaCl2 applications. Foliar CaCl2 applications increased foliar Ca content by 60%. Concentrations of other plant nutrients other than N and Ca were decreased in parallel with increasing CaCl2 doses. Foliar P content was not affected in this case. As a result, the amount of CaCl2 solution to be applied to leaves in Hicaznar pomegranate was determined as 0.6%.

Balık atıkları besinsel açıdan değerli, fonksiyonel özelliklere sahip ve kolay sindirilebilir, ekonomik değeri yüksek proteinli ürünlere dönüştürülebilirler. Balık işleme atıklarından kullanılabilir gıda ve biyoaktif bileşiklerin dönüşümü ile ilgili çalışmalara ve ticari üretime ağırlık verilmiştir. Balık protein hidrolizatları (BPH) ticari ürün olarak fonksiyonel gıda, hayvansal yem, organik gübre ve evcil hayvan gıdası olarak kullanıldığı gibi BPH’ larının içerdikleri nutrasötik özellikteki biyoaktif peptitler ile antihipertensif, antitrombotik, antikanser, immunomodulatör ve antioksidan aktivitesi gösterdikleri için tıp ve farmakolji alanında da değerlendirilmektedir. Hidrolizatlarının besleyici özelliklerinin, diğer protein hidrolizatlarından daha dengeli ve üstün olduğunu göstermektedir. Protein hidrolizatı üretmek için kimyasal ve enzimatik olmak üzere iki farklı yöntem kullanılmaktadır. Son zamanlarda; daha düşük sıcaklık, basınç ve 5-8 arası bir pH aralığı kullanıldığı için enzimatik yöntemle hidrolizat üretimini daha cazip hale getirmiştir. Hidrolizasyonun en etkili göstergesi hidroliz derecesi (HD(%)) olarak kullanılmıştır. Yapılan çalışmalardan elde edilen bulgulara göre, protein geri kazanımı için parçalanmış peptit bağlarının daha yüksek olması, HD(%)’ nin yükselmesine neden olmaktadır. Küçük molekül ağırlığına sahip proteinlerin suda daha fazla çözünürlüğü, hidrolizatın protein geri kazanımını artırarak, fonksiyonel özelliklerini daha kullanılabilir hale getirmektedir. Araştırmalarda elde edilen farklı değerlerin balık türlerine, atık kompozisyonuna, enzim türüne, hidroliz yöntemine (sıcaklık, süre ve enzim oranı) göre değişebileceği görülmektedir. Bu araştırmada balık işleme atıklarından enzimatik hidroliz yöntemi kullanılarak balık protein hidrolizatı üretimi konusu derlenmiştir.
