Published: August 2019

Background::Unripe grape (Qoura) in the forms of either intact or juice can be used as a flavoring agent in several foods of Iranian cuisines such as soup and salad due to its sour taste.Methods::In the current study, the effects of microwave (270, 540, and 720 W) and hot air drying (40, 50 and 60°C) on the polyphenol components content and chemical properties (including chroma, hue angle, L* value, total color difference, soluble sugars, acidity, total phenols and phenolic components including rutin, gallic acid, hydroxybenzoic acid, syringic acid, p-coumaric acid, and resveratrol) of Qoura obtained from unripe white seedless grape were investigated.Results::The obtained results showed that in both methods, by increasing the oven temperature and microwave power, the L value (The L* value was used to express the whiteness and darkness) was decreased. There was a notable reduction in the initial phenolic content of the sample (381.671 mg gallic acid/ 100 g) as a result of both of the used techniques. The initial content of resveratrol was decreased from 30.27 mg/100 g; to 23.07, 16.64, 10.73 mg/100 g sample in the samples treated with the air-drying method at 40, 50, 60°C, respectively. Also, by using the microwave in 270, 540, 720 W, it decreased to 5.77, 5.38. 5.26 mg/100 g sample at 270, 540, 720 Watt, respectively.Conclusion::The results of the present study revealed that the drying method affects the amount of polyphenolic compounds and physicochemical properties.

:
Cardiovascular Disease (CVD) in Systemic Lupus Erythematosus (SLE) and Neuropsychiatric
SLE (NPSLE) has an estimated prevalence of 50% and 40%, respectively and both constitute
major causes of death among SLE patients. In this review, a combined brain/heart Magnetic
Resonance Imaging (MRI) for SLE risk stratification has been proposed.

:
The pathophysiologic background of NPSLE includes microangiopathy, macroscopic infarcts and
accelerated atherosclerosis. Classic brain MRI findings demonstrate lesions suggestive of NPSLE
in 50% of the NPSLE cases, while advanced MRI indices can detect pre-clinical lesions in the majority
of them, but their clinical impact still remains unknown. Cardiac involvement in SLE includes
myo-pericarditis, valvular disease/endocarditis, Heart Failure (HF), coronary macro-microvascular
disease, vasculitis and pulmonary hypertension. Classic and advanced Cardiovascular
Magnetic Resonance (CMR) indices allow function and tissue characterization for early diagnosis
and treatment follow-up of CVD in SLE.

:
Although currently, there are no clinical data supporting the combined use of brain/heart MRI in
asymptomatic SLE, it may have a place in cases with clinical suspicion of brain/heart involvement,
especially in patients at high risk for CVD/stroke such as SLE with antiphospholipid syndrome
(SLE/APS), in whom concurrent cardiac and brain lesions have been identified. Furthermore, it
may be of value in SLE with multi-organ involvement, NPSLE with concurrent cardiac involvement,
and recent onset of arrhythmia and/or heart failure.
Modified Local Binary Pattern Algorithm for Feature Dimensionality Reduction
Authors: Kumar Manish , Gupta Rahul , Raju Kota S. , Kumar Dinesh 
Published: August 2019

Background:
Bio metric authentication is becoming popular now a days and becoming
integral part of IoT and other systems. Face recognition is one of the major and important aspect of
bio metric systems after the fingerprint.

Objective:
A face recognition algorithm with feature dimensionality reduction is proposed which is
very much required in recognition system for high speed and accuracy.

Methods:
The proposed algorithm is based on a variant of Local Binary Pattern (LBP) for face detection
and recognition. The features of each block of face image is extracted and then global feature
of face is constructed from super histogram.

Results:
For recognition, traditional methods are used. The query image is compared with the data
set (ORL Dataset, LFW Dataset and Yale Dataset) in similarity index and the minimum distance.
The maximum similarity is used to define as the class of query image. The reduction in number of
features is achieved by modifying the traditional LBP process.

Conclusion:
The proposed modified method is observed as more fast and efficient for face recognition
as compared to the existing algorithms.

Background:Eusiderin A is a neolignan derivate, which makes up the majority of the secondary metabolite of Eusideroxylon zwageri. It has been reported as a potent biopesticide and antifungal agent. Previous studies on the oxidation of terminal methylene of the allylic chain in Eusiderin A have been able to produce primary alcohol, pinacol, and an aldehyde which demonstrated strong activity against plant pathogenic fungi, therefore activity against dermal fungi needs to be studied.Objective:The current study aims to improve the hydrophilicity of Eusiderin A via oxidation of the allylic chain in order to derive a potent antifungal property.Methods:Transformation of Eusiderin A has been achieved by using the Wacker Oxidation Method in combination with the α-Hydroxylation-Ketone Method to produce 7,3’-epoxy-8,4’-oxyneolignane-1’- carboxylic acid. The structure of the 7,3’-epoxy-8,4’-oxyneolignane-1’-carboxylic acid was identified from spectroscopy data. The in vitro antifungal activity study was performed using the paper disc diffusion method against Trichophyton mentagrophytes.Results:New molecule of natural Eusiderin A through the oxidation of the allylic chain to increase the hydrophilicity of Eusiderin A has been designed. Based on the observed UV, IR, 1H and 13C-NMR, and MS spectra, it can be stated that the 7,3’-epoxy-8,4’-oxyneolignane-1’-carboxylic acid has been formed. At a concentration of 50 ppm, this compound showed antifungal activity against Trichophyton mentagrophytes.Conclusion:It can be concluded that the 7,3’-epoxy-8,4’-oxyneolignane-1’-carboxylic acid is a potent antifungal agent as it is able to inhibit the Trichophyton mentagrophytes colonies growth.
Listening to Young Children: A Mosaic approach
Authors: Tan Poh 
Published: August 2019

The inclusion of children’s responses in research of educational settings are important and have been described as a pertinent tool to understand and be aware of children’s perspectives that adults may not be aware of (Lundqvist, 2014). Sheridan (2011) further expresses that the “evaluation of quality of early childhood education must include the voices of children” and is an essential part of the overall understanding of early childhood education. The responses and voices of young children reflect diverse forms of communicating, representing and interpreting their thoughts and emotions. This paper will present some models that can help guide the researcher to make decisions about how a child can participate in the research activity. Specifically, I will describe the use of an ethnographic combined with Clark and Moss’s Mosaic approach to researching with children.
Needs Analysis as a Measure for the Accuracy of ESP Syllabus Courses in Kurdistan Technical Institutes, Department of Administration as a Case Study
Authors: Najmaddin Shler Mohammed Ali , Hama Sur Shilan Ali 
Published: August 2019

ESP courses are used in all Higher Education institutions in Kurdistan/Iraq. These courses are supposed to provide students with both awareness and skills to handle communication in English in the target subjects. This paper addresses the effect and shortcomings of “Administrative Reading in English’, an ESP course taught in Kurdistan Technical Institutes. The paper examines the extent to which these courses fit the needs of Kurdish students; and whether the curricula of the course reflect the characteristics of a systematic standard ESP course. Data was collected through a questionnaire distributed to three different student groups and interviews were conducted with instructors. The data is used to identify the drawbacks of the course material; and investigate the relevance of the teaching methods, assessment and the language used, to the level, motivation and needs of the students. The research concludes that a solid curriculum that takes into consideration students’ motivation for learning as well as their receptive and productive learning skills has not been correctly constructed for the courses in general.
METHOD DEVELOPMENT AND VALIDATION OF SELECTIVE AND HIGHLY SENSITIVE METHOD FOR DETERMINATION OF APIXABAN IN HUMAN PLASMA USING LIQUID CHROMATOGRAPHY-TANDEM MASS SPECTROMETRY
Authors: ATMAKURI CHAITANYA KRISHNA , PRASAD CHEEPURUPALLI , S. PATIL RAJARAM , DHARANI KARUNAKRANTH 
Published: August 2019

Objective: The present research work aims to develop and validate a selective and highly sensitive method for the determination of apixaban in human plasma using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Methods: 200 µl of sodium heparin plasma samples were acidified and clean-up was performed by using solid-phase extraction (SPE). Apixaban 13C D3 was used as an internal standard (deuterated) to lower the relative matrix effects and a single step SPE was employed for sample clean up. 10 µl of SPE eluent was loaded onto Hypersil Beta Basic C18, 100×4.6 mm, 5 µ column for highly selective chromatographic separation using an isocratic mobile phase. 2 mmol ammonium acetate in water and acetonitrile were delivered by using a quaternary low-pressure gradient pump without premixing at a minimum flow rate of 0.50 ml/min.
Results: LC-MS/MS method was successfully developed and validated to demonstrate the lowest detection limit of 0.05 ng/ml and a linear dynamic range from 1-250 ng/ml with r2>0.99. Method development and validation results proved that the method is selective and highly sensitive for the determination of apixaban in human plasma using LC-MS/MS.
Conclusion: Current method can be applied for both therapeutic drug monitoring (TDM) and pharmacokinetic (PK) study analysis.
Fires and volcanic activity: History of fire in the Mexico basin during late Pleistocene based on carbonized material records in the Chalco lake
Authors: Martínez-Abarca Rodrigo , Lozano-García Socorro , Ortega-Guerrero Beatriz , Caballero-Miranda Margarita 
Published: August 2019

Forest fires, considered as free and not programmed fire propagation, are perturbations that greatly alter ecosystems. During fires, variable quantities of charcoal particles are produced by the burning vegetation, which can be later deposited in lacustrine basins. The traditional charcoal size particle model associates the > 100 µm primary particles to local fire events, within the watershed, and the < 100 µm particles are linked to regional fire events, outside the watershed. Fires can be related with favorable climatic conditions, but in tectonically active areas like the basin of Mexico, volcanism can also be a factor producing fires and charcoal particles. We document the history, intensity and frequency of fires recorded in the lacustrine sediments of lake Chalco (core CHAVII-11), by performing a high-resolution charcoal particle analysis in sediments deposited before and after three main volcanic events. The sources of these events had different distances to lake Chalco: Tláhuac tephra (TTH; 28690 years cal BP), probably produced by the Teuhtli volcano, was a local event; the Tutti Frutti Pumice (PTF; 17000 years cal BP) produced by the Popocatépetl volcano, was an extra-local event and the Upper Toluca Pumice (PTS; 12300 years cal BP) produced by the Nevado de Toluca volcano, was a regional event. Charcoal accumulation rates (CHAR) and distribution of size particles indicate that paleoclimate was a direct factor defining the intensity and recurrence of fires before and after volcanic activity, as climate defines vegetation type and density, and therefore fuel availability. Fires before and after the TTH were frequent, local and intense in comparison with fires reconstructed before or after the PTF and PTS events. CHAR values were lower during the more widespread PTF event, than for the local TTH event, although the highest CHAR values were recorded for the most distant, regional, and intense PTS event. These results show that charcoal accumulation rates during the volcanic events in central Mexico cannot be interpreted following traditional model of charcoal particle dispersion. This model have important restrictions in active volcanic regions such as central Mexico.
What Do Employees Know? Evidence from a Social Media Platform
Authors: Huang Kelly , Li Meng , Markov Stanimir 
Published: August 2019

ABSTRACT
We use employee predictions of their companies' six-month business outlook from Glassdoor.com to assess the information content of employee social media disclosures. We find that average employee outlook is incrementally informative in predicting future operating performance. Its information content is greater when the disclosures are aggregated from a larger, more diverse, more knowledgeable employee base, consistent with the wisdom of crowds phenomenon. Average outlook predicts bad news events more strongly than good news events, suggesting that employee social media disclosures are relatively more important as a source of bad news. Consistent with the organizational theory, we find systematic differences in the quantity and nature of the information in employee disclosures when the disclosures are grouped based on employee attributes and job responsibilities. Finally, average outlook predicts future returns of firms that attract less attention by analysts and investors, suggesting that investors in these firms use outlook inefficiently.

O artigo traz um quadro aproximado da ocupação pré-colonial na planície aluvial e nos terraços do rio Araguaia utilizando informações de projetos de pesquisa preventiva e acadêmica, trabalhos científicos, dois estudos de casos e dados de sítios fora desse ambiente, para ampliar o contexto ocupacional, especialmente no que se refere a sítios lito-cerâmicos. Ao longo dos tempos, o rio Araguaia foi um elemento significativo da paisagem para a ocupação humana no Planalto Central brasileiro. Relatos históricos mencionam aldeias indígenas junto às suas margens. Em relação a ocupação pré-colonial esse rio localiza-se estrategicamente entre o norte e o sul do País e da América do Sul, sendo uma via de deslocamento favorável entre as bacias amazônica e platina. A planície aluvial e os terraços apresentam uma série de sítios arqueológicos lito-cerâmicos de grupos agricultores e ceramistas, predominantemente da Tradição Uru. Na bacia hidrográfica do rio Araguaia, também ocorrem sítios pré-cerâmicos e de agricultores e ceramistas de outras tradições arqueológicas, de superfície e em abrigos rochosos com reocupações, havendo alguns com pinturas e gravuras rupestres. Nessa abordagem, mostra-se a estruturação da bacia do rio Araguaia como tema fundamental para a Arqueologia, visualizando a relação com os sistemas fluviais, análise espacial dos sítios, processos de formação do registro arqueológico, e apropriação e construção da paisagem.
Ideias de alunos sobre o “seu” passado doloroso a Guerra Colonial Portuguesa*

Published: August 2019

Quando se fala de identidade, de consciência europeia, de tolerância, de intervenção cívica, de solidariedade,... a História é requisitada para desempenhar um papel e uma função marcadamente sociais. Por outro lado, quando se questionam os jovens europeus sobre o significado da História, vislumbram-se nas suas respostas a “valorização da História como fonte de aprendizagem” e o respeito pela monumentalidade do passado. O projeto que aqui apresentamos, “Enseigner les passés douloureux en Europe”, tem o objetivo claro de evitar o esquecimento, trazer a densidade histórica que garanta o correto conhecimento do passado, dotar os alunos de competências críticas para assumirem as responsabilidades dos “deveres da memória”. O foco desta pesquisa é tentar perceber como os jovens refletem a questão da reparação histórica como, por exemplo, pensar sobre a justificação, viabilidade, motivos e efeitos de reparação de injustiças históricas. Estas reflexões são uma importante janela para a consciência histórica dos jovens: ao observarmos como refletem sobre a questão da reparação histórica, podemos ver como concebem os limites da responsabilidade individual e coletiva e a responsabilidade moral do Estado e dos seus cidadãos.

Luis Xavier tentou regressar à Bahia a fim de liquidar seus bens e prometia voltar para a costa africana assim que o fizesse, mas por diversas razões, seu regresso à província não foi autorizado.
DOCUMENTARTE Encontro com documentos e pensamento professoral no ensino de História
Authors: Helbich Luciane , Pereira Nilton Mullet 
Published: August 2019

Este é um trabalho com um perfil histórico-filosófico. Procura discutir os conceitos de pensamento e de encontro, a partir da relação entre o professor de História e os documentos, e tendo como fontes de inspiração Deleuze, Foucault e Spinoza. Nesse sentido, compreende a criação de narrativas como o momento privilegiado da prática professoral, na Escola Básica, revelando-se como um processo que decorre de uma violência do pensamento, ensejado pelos encontros entre um fazer professoral e os documentos históricos. O ofício do professor de História é considerado como um fazer artístico e gerador de histórias-problema. Nesta perspectiva, as narrativas pensadas a partir do encontro do professor com os documentos são apresentadas como um movimento de imaginação criativa. Procura-se lançar novos olhares sobre as experiências com os documentos e entendê-las como atualização de virtualidades que a potência dos documentos disponibiliza. Pensando a partir da filosofia da diferença, este texto busca a empiria com a matéria de expressão, que são os documentos que dão consistência à criação de um novo plano de pensamento.
À luz da contradição: projetos neocolonialistas na oposição ao Estado Novo Português
Authors: Santos Alves da Silva Franco 
Published: August 2019

O colonialismo do Estado Novo português foi um dos pilares que sustentavam o discurso da grandeza do império ultramarino, e da suposta facilidade com que Portugal estabelecia e mantinha contatos com outras culturas. Entretanto, no contexto do final da década de 1950 e início de 1960, o mundo não via com bons olhos a posse de colônias na África, como também do surgimento de diversos movimentos de resistência em Angola e Moçambique, a oposição passou a enfatizar o apoio a estes movimentos, além de denunciar os abusos cometidos em território africano, para, desta forma, buscar o próprio fim do regime. Nas páginas do jornal Portugal Livre, editado no Brasil, surgiram algumas propostas para a “questão colonial”, aonde traçavam projetos políticos de emancipação para as colônias. Escrito pelo capitão Henrique Galvão e pelo general Humberto Delgado, ambos antigos defensores do sistema colonial e dissidentes do regime, as propostas eram permeadas por um discurso neocolonialista que ajudou a aumentar o abismo existente na oposição e expor que a mentalidade colonial estava mais presente na oposição, e na própria cultura portuguesa, do que eles mesmo supunham.

Published: August 2019

Gelatin of skin tilapia (Oreochromis niloticus) has the potential as an edible film but has weaknesses due to the hydrophilic so that the value of the water vapor transmission rate is high. The addition of carrageenan combined with palmitic acid is used to improve the characteristics of edible films modified bythe polymer network so that it can act as cross linking which is expected to reduce the rate of water vapor transmission rate edible film. indigo and get the best carrageenan concentration edible film seen from the value of the water vapor transmission rate. The ingredients used are tilapia skin gelatin, carrageenan and palmitic acid. The research method used was experimental laboratories with completely randomized design (CRD) experimental design. Parameters observed were thickness test, solubility, tensile strength, percent elongation and water vapor transmission rate. Data were analyzed using variance analysis (ANOVA). To find out the differences between treatments, the data was tested by HSD further tests. The results showed that the difference in carrageenan concentration significantly affected (P<0,05) the thickness value, tensile strength, percent elongation, solubility and water vapor transmission rate. Addition of carrageenan 0.8% was the best result which has a tensile strength of 4.209 ± 0.241 MPa, elongation percent 16.332 ± 1.019%, solubility of 65.911 ± 2.930% and water vapor transmission rate of 7.792 ± 0.376 g / m2. Hour. Testing of tensile strength in 0,8% carrageenan film showed that the film matrix binds so that the film was not easily broken compared to the control. The low water vapor transmission rate in the 0.8% carrageenan addition edible film sample showed the formation of cross linking between gelatin and carrageenan protein molecules.
