Published: December 2018

Daun sukun (Artocarpus altilis) sudah lama dijadikan sebagai obat tradisional untuk mengatasi berbagai penyakit seperti liver cirrhosis, hipertensi, dan diabetes. Ekstrak etil asetat dari daun sukun juga berpotensi menghambat pertumbuhan sel kanker. Beberapa senyawa yang telah diketahui sebagai agen antikanker di dalam ekstrak etil asetat daun sukun adalah golongan geranil flavonoid. Akan tetapi, senyawa pyranoflavoid belum dilaporkan dapat ditemukan pada daun sukun. Untuk itu, penelitian ini bertujuan untuk mengisolasi senyawa pyranoflavonoid dari ekstrak etil asetat daun sukun dan menguji aktivitasnya sebagai antikanker. Daun sukun diekstraksi dengan etanol 70% kemudian dilakukan partisi dengan petroleum eter dan etil asetat. Ekstrak etil asetat yang diperoleh difraksinasi dengan kromatografi kolom silica gel dengan gradient elusi heksan-etil asetat sehingga diperoleh senyawa kristal berwarna kuning, AA3. Senyawa AA3 kemudian diidentifikasi dengan spektrofotometer UV-Vis, LC-MS, 1H-NMR dan 13C-NMR dan diperoleh hasil bahwa senyawa AA3 tersebut adalah siklokomunol yang merupakan golongan pyranoflavonoid. Uji antikanker siklokomunol dengan MCF-7 dan T47D menunjukkan adanya aktivitas antikanker dengan nilai IC50 masing-masing adalah 75.46 µM dan 36.20 µM selama 48 jam.Kata kunci:Artocarpus altilis, siklokomunol, antikanker, MCF-7, T47D. Leaves of breadfruit Artocarpus altilis (Parkinson) Fosberg has long been used as traditional medicine to overcome a variety of diseases such as liver cirrhosis, hypertension, and diabetes.

Exploring the Acetone Evaporation and Airborne Neurotoxicity Bioassay against Adult Mosquito in the Enclosed Environment of Peet Grady Chamber
Authors: Kamaldin Jahangir , Jaal Zairi
Published: December 2018

Mosquito has comprehensive and sensitive olfactory neuro-sensory located at antenna utilized for detecting airborne organic compounds in search of blood host. Mosquito is also known to have similar neurotransmitters function with human at neural synapses e.g. acetylcholinesterase, esterases and oxidases enzymes. Thus, there is potential use mosquito in predicting neurotoxicity of exogenic volatile organic compounds (VOC) e.g. manufactured acetone. Hence, the study evaluates the suitability to conduct bioassay of VOC neurotoxicity against mosquito in Peet Grady chamber that is commonly used for insecticidal bioassay. Acetone as the representative of VOC is easily evaporized at laboratory temperature of 26 to 29 °C without heating. The acetone evaporation profile on liquid surface and porous solid surface under the Peet Grady chamber is studied to ascertain the consistency of vaporization rate with homogenized distribution. The study showed the acetone has shown consistent vaporization rate of 23 mg/min from liquid surface and 116.3 mg/min from porous surface (filter paper) without heating, in a linear regression of very high positive correlation (r = 1.000) between time and mass of acetone vaporized. However, the non-homogenized distribution of acetone vapours in the Peet Grady chamber directly affected the accuracy to elucidate the neurotoxicity bioassay against mosquito in term of mosquito knockdown. The study suggests the positioning of mosquitoes in the Peet Grady chamber should be lower than the point of acetone vaporization, whereby the mosquitoes are knockdown by acetone vapours within the 20th minute upon reaching concentration of 170.3 to 196.1 ppm.
Bearly Guilty: Understanding Human–Andean Bear Conflict Regarding Crop Losses
Authors: Albarracín Viviana , Aliaga-Rossel Enzo
Published: December 2018

Conflicts between wildlife and humans are increasing worldwide, especially in areas where they coexist and share resources. To investigate attitudes and opinions of the human population towards human-Andean bear (Tremarctos ornatus) conflicts in two indigenous Aymara communities, Chuñavi and Lambate, Bolivia, semi-structured interviews were directed to an adult member of families in the communities. Simultaneously, we registered, monitored, and evaluated 70 farm plots to record evidence of Andean bear and other wildlife damage to the maize crops and plants. We found that the locals thought the bear caused the most damage when, in actuality, the most harmful issues identified for maize crops were environmental factors, followed by parrots and birds. Knowledge of the interactions between wild animals and productive systems can contribute to an understanding of Andean bear-human coexistence.

$(p,q)$th order oriented growth measurement of composite $p$-adic entire functions
Authors: Biswas T.
Published: December 2018

Let $\mathbb{K}$ be a complete ultrametric algebraically closed field and let $\mathcal{A}\left(\mathbb{K}\right)$ be the $\mathbb{K}$-algebra of entire functions on $\mathbb{K}$. For any $p$-adic entire function $f\in \mathcal{A}\left( \mathbb{K}\right) $ and $r>0$, we denote by $|f|\left(r\right)$ the number $\sup \left\{ |f\left( x\right) |:|x|=r\right\}$, where $\left\vert \cdot \right\vert (r)$ is a multiplicative norm on $\mathcal{A}\left( \mathbb{K}\right)$. For any two entire functions $f\in \mathcal{A}\left(\mathbb{K}\right)$ and $g\in \mathcal{A}\left(\mathbb{K}\right)$ the ratio $\frac{|f|(r)}{|g|(r)}$ as $r\rightarrow \infty $ is called the comparative growth of $f$ with respect to $g$ in terms of their multiplicative norms. Likewise to complex analysis, in this paper we define the concept of $(p,q)$th order (respectively $(p,q)$th lower order) of growth as $\rho ^{\left( p,q\right) }\left( f\right) =\underset{r\rightarrow +\infty }{\lim \sup } \frac{\log ^{[p]}|f|\left( r\right) }{\log ^{\left[ q\right] }r}$ (respectively $\lambda ^{\left( p,q\right) }\left( f\right) =\underset{ r\rightarrow +\infty }{\lim \inf }\frac{\log ^{[p]}|f|\left( r\right) }{\log ^{\left[ q\right] }r}$), where $p$ and $q$ are any two positive integers. We study some growth properties of composite $p$-adic entire functions on the basis of their $\left(p,q\right)$th order and $(p,q)$th lower order.
On central automorphisms of crossed modules
Authors: Dehghani M. , Davvaz B.
Published: December 2018

A crossed module $(T,G,\partial)$ consist of a group homomorphism $\partial:T\rightarrow G$ together with an action $(g,t)\rightarrow{}^{\,g}t$ of $G$ on $T$ satisfying $\partial(^{\,g}t)=g\partial(t)g^{-1}$ and $\,^{\partial(s)}t=sts^{-1}$, for all $g\in G$ and $s,t\in T$. The term crossed module was introduced by J. H. C. Whitehead in his work on combinatorial homotopy theory. Crossed modules and its applications play very important roles in category theory, homotopy theory, homology and cohomology of groups, algebra, K-theory etc. In this paper, we define Adeny-Yen crossed module map and central automorphisms of crossed modules. If $C^*$ is the set of all central automorphisms of crossed module $(T,G,\partial)$ fixing $Z(T,G,\partial)$ element-wise, then we give a necessary and sufficient condition such that $C^*=I_{nn}(T,G,\partial).$ In this case, we prove $Aut_C(T,G,\partial)\cong Hom((T,G,\partial), Z(T,G,\partial))$. Moreover, when $Aut_C(T,G,\partial)\cong Z(I_{nn}(T,G,\partial)))$, we obtain some results in this respect.
Unconventional analogs of single-parametric method of iterational aggregation
Authors: Demkiv I.I. , Kopach M.I. , Obshta A.F. , Shuvar B.A.
Published: December 2018

When we solve practical problems that arise, for example, in mathematical economics, in the theory of Markov processes, it is often necessary to use the decomposition of operator equations using methods of iterative aggregation. In the studies of these methods for the linear equation $x=Ax+b$ the most frequent are the conditions of positiveness of the operator $A$, constant $b$ and the aggregation functions, and also the implementation of the inequality $\rho(A) <1$ for the spectral radius $\rho(A)$ of the operator $A$.

In this article for an approximate solution of a system composed of the equation $x = Ax + b$ represented in the form $ x = A_1x + A_2x + b, $ where $ b \in E, $ $ E $ is a Banach space, $ A_1, A_2 $ are linear continuous operators that act from $ E $ to $ E $ and the auxiliary equation $ y = \lambda y - (\varphi, A_2x) - (\varphi, b) $ with a real variable $ y $, where $ (\varphi, x) $ is the value of the linear functional $ \varphi \in E ^ * $ on the elements $ x \in E $, $ E^* $ is conjugation with space $ E $, an iterative process is constructed and investigated \begin{equation*} \begin{split} x^{(n+1)}&=Ax^{(n)}+b+\frac{\sum\limits_{i=1}^{m}A^i_1x^{(n)}}{(\varphi, x^{(n)})\sum\limits_{i=0}^{m}\lambda^i}(y^{(n)}-y^{(n+1)}) \quad (m<\infty),\\ y^{(n+1)}&=\lambda y^{(n+1)}-(\varphi,A_2x^{(n)})-(\varphi,b). \end{split} \end{equation*}

The conditions are established under which the sequences $ {x ^ {(n)}}, {y ^ {(n)}}$, constructed with the help of these formulas, converge to $ x ^ *, y ^ * $ as a component of solving the system constructed from equations $ x = A_1 x + A_2 x + b $ and the equation $ y = \lambda y - (\varphi, A_2 x) - (\varphi, b) $ not slower than the rate of convergence of the geometric progression with the denominator less than $1$. In this case, it is required that the operator $ A $ be a compressive and constant by sign, and that the space $ E $ is semi-ordered. The application of the proposed algorithm to systems of linear algebraic equations is also shown.
On the crossings number of a hyperplane by a stable random process
Authors: Osypchuk M.M.
Published: December 2018

The numbers of crossings of a hyperplane by discrete approximations for trajectories of an $\alpha$-stable random process (with $1<\alpha<2$) and some processes related to it are investigated. We consider an $\alpha$-stable process is killed with some intensity on the hyperplane and a pseudo-process that is formed from the $\alpha$-stable process using its perturbation by a fractional derivative operator with a multiplier like a delta-function on the hyperplane. In each of these cases, the limit distribution of the crossing number of the hyperplane by some discret approximation of the process is related to the distribution of its local time on this hyperplane. Integral equations for characteristic functions of these distributions are constructed. Unique bounded solutions of these equations can be constructed by the method of successive approximations.

Increasing amount of international students in Russian Federation in recent years has caused changes in the content and structure of foreign languages learning. Communicative competence in conditions of multilingualism becomes the basis for fundamental professional training of international students. In this regard, productive method of teaching foreign languages allows systematizing methodological basis for integrated language learning by international students. Moreover, foreign languages learning based on the core principles of productive method provides students’ creative development and self-realization intensified by linguodidactic technology Personal multilinguistic portfolio (PMP) developed by us. The article reveals the content of this linguodidactic technology in the system of international students’ professional training. The paper shows theoretical and practical methodological aspects of teaching foreign languages to international students who have low level of Russian and middle or low level of the English language. To verify this technology we conducted the experiment using the methods of scientific and pedagogical research. As a result we found out how the English, Russian and native languages may interact and correlate with each other during the foreign languages learning. We determined the dynamics of students’ communicative competence formation, including linguistic and discourse aspects. The results of the experiment showed the effectiveness of the developed PMP technology and its successful introduction in the educational process.

Deslocamento de óleo por água em um microcanal com cavidade de quinas arredondadas
Authors: Rigatto Suellen Freire , Romero Oldrich Joel
Published: December 2018

No presente estudo é analisado numericamente, com auxílio do software Ansys Fluent, a mobilização de óleo mediante injeção de água em uma geometria bidimensional formado por placas paralelas com uma microcavidade quadrada que, de forma simplificada, representa as gargantas e poros da rocha-reservatório portadora de óleo. O objetivo fundamental é avaliar a influência da curvatura da quina no processo de mobilização do óleo. Para isso, o efeito de três raios de curvatura são comparados com a quina formada por um ponto. O problema é transiente, bifásico, com forças capilares dominantes sobre as viscosas e as de inercia. Os resultados obtidos, para o caso com quina aguda, é coincidente com o trabalho de Coelho, Pena e Romero (2016). A análise dos casos considerados permitem destacar que ao final do processo de deslocamento uma fração de óleo continuará trapeado na microcavidade. Também, para a geometria considerada e independente do raio de curvatura da quina, existem três regiões distintas ao se avaliar a fração volumétrica média de óleo. A primeira região em que a redução de óleo é acentuada. Uma segunda região onde a retirada de óleo torna-se cada vez mais lenta. E uma terceira que identifica a saturação de óleo residual. Finalmente, o processo se torna mais eficiente quanto maior for o raio de curvatura da quina do microporo. Esta relação, pelo menos para os casos analisados, é linear.

Published: December 2018

A perda dental é um dos grandes problemas da Odontologia. Com os avanços tecnológicos, o implante dentário veio para realizar reposições de dentes extraídos. O uso de impressões 3D trouxe a possibilidade da reprodução das arcadas dentárias de forma fidedigna, graças ao programa InVesalius que processa imagens tomográficas transformando-as em um arquivo capaz de reproduzir por meio de impressão um protótipo dimensionalmente fiel. Com relação ao Odontólogo, a prototipagem ofereceu grandes benefícios, tais como, clareza no planejamento cirúrgico e segurança na execução dos procedimentos, além de permitir ao paciente elucidação prévia do processo, diminuindo inúmeras insatisfações e dúvidas quanto ao tratamento proposto. Aliados às vantagens oferecidas ao dentista e ao paciente, pelo protótipo 3D, o fator custo é de suma importância devido à sua irrelevância quanto ao valor total de um implante dentário frente aos benefícios oferecidos decorrentes do uso da prototipagem 3D. Este trabalho apresenta o processo de geração de um modelo tridimensional por meio do software Invesalius e a impressão deste, com posterior teste de implante dentário.

Authors: Mahoodi Malihe
Published: December 2018

In this paper, the effect of diffraction grating and engineering absorber and back surface field (BSF) layers on performance of a single-junction polycrystalline cadmium sulfide/cadmium telluride (CdS/CdTe) solar cell have investigated. At first, the electrical characteristics of reference CdS/CdTe solar cell is simulated and validated with experimental data of fabricated CdS/CdTe solar cell. In order to improve the maximum efficiency, a new structure with diffraction grating and engineering absorber and back surface field layers is presented. Furthermore, the effect of carrier lifetime variation in the absorber layer on the conversion efficiency of solar cell was investigated. It is found that diffraction grating and engineering absorber and back surface field layers can increase the conversion efficiency of the solar cell by about 1.02% and 6% compared with reference cell, respectively. Under global AM 1.5 conditions, the open circuit voltage, short circuit current density, fill factor and conversion efficiency of optimized solar cell structure are 1114 mV, 25.35 mA/cm2, 0.8856 and 25.022%, respectively.

Published: December 2018

O concreto pré-fabricado é um sistema construtivo que possibilita uma rápida execução, controle de qualidade e que facilita a racionalização da obra. Contudo o nível de defeitos e a qualidade do acabamento das peças são determinados qualitativamente através de inspeção visual e comparativos com padrões fotográficos. O objetivo deste trabalho é propor uma metodologia para a classificação da qualidade superficial das peças de concreto pré-fabricadas através da análise de imagens, reduzindo assim o caráter subjetivo e melhorando o processo na planta de produção.  Para isto foram moldadas peças pré-fabricadas com concreto produzido em central. As imagens foram coletadas em pontos pré-definidos e analisadas individualmente por um software de analise de imagens, “image tool”. Após um tratamento prévio nas imagens foi possível determinar a quantidade superficial de bolhas e defeitos, e a variação dimensional dos mesmos. Foi realizada então uma comparação com as imagens fornecidas pelo Guide for surface finish of formed concrete do qual foi compilada uma tabela de distribuição de tamanho e densidade de defeitos. O processo de classificação da qualidade superficial das peças de concreto pré-fabricados pôde assim ser obtido de maneira sistemática utilizando-se a análise de imagens.
Adverse Event Management in Patients with BRAF V600E-Mutant Non-Small Cell Lung Cancer Treated with Dabrafenib plus Trametinib
Authors: Chalmers Anna , Cannon Laura , Akerley Wallace
Published: December 2018

Therapies for advanced non-small cell lung cancer (NSCLC) continue to become more sophisticated. Chemotherapeutics are giving way to newer approaches such as immune checkpoint inhibitors and targeted therapies for greater efficacy and improved outcomes. Dabrafenib plus trametinib combination therapy was first approved for the treatment of metastatic melanoma harboring the BRAF V600-mutation in 2014. In 2017, the U.S. Food and Drug Administration approved the combination for patients with NSCLC with the same mutation based on an ≈ 65% response rate and median progression-free survival of 10–11 months. BRAF mutations are a high-frequency event in melanoma (≈ 50%), whereas the overall incidence in lung cancer is ≈ 2%, but similar in number, because of the high incidence of the disease. As a new approach in NSCLC treatment, dabrafenib plus trametinib has a unique toxicity profile that is likely unfamiliar to care providers in thoracic and general oncology who have not used the combination to treat patients with melanoma. Common adverse events such as pyrexia, fatigue, and nausea, as well as a range of less frequent cutaneous, ocular, and hemorrhagic events, can be observed during treatment with dabrafenib plus trametinib. Previous experience in metastatic melanoma revealed that these events can be effectively managed to improve patient quality of life and reduce unnecessary drug discontinuation. The aim of this review is to summarize treatment guidelines, along with key insights obtained from previous clinical-trial and real-world experience in patients with metastatic melanoma, to properly manage toxicities associated with dabrafenib plus trametinib for NSCLC.

Background

The expression of depressive symptoms in older people with cancer is heterogeneous because of specific features of age or cancer comorbidity. We aimed to identify depressive symptom profiles in this population and describe the associated features including survival.

Materials and Methods

Patients ≥70 years who were referred to geriatric oncology clinics were prospectively included in the ELCAPA study. In this subanalysis, depressive symptoms were used as indicators in a latent class analysis. Multinomial multivariable logistic regression and Cox models examined the association of each class with baseline characteristics and mortality.

Results

For the 847 complete-case patients included (median age, 79 years; interquartile range, 76–84; women, 47.9%), we identified five depressive symptom classes: “no depression/somatic only” (38.8%), “no depression/pauci-symptomatic” (26.4%), “severe depression” (20%), “mild depression” (11.8%), and “demoralization” (3%). Compared with the no depression/pauci-symptomatic class, the no depression/somatic only and severe depression classes were characterized by more frequent comorbidities with poorer functional status and higher levels of inflammation. “Severe” and “mild” depression classes also featured poorer nutritional status, more medications, and more frequent falls. Severe depression was associated with poor social support, inpatient status, and increased risk of mortality at 1 year (adjusted hazard ratio, 1.62, 95% confidence interval, 1.06–2.48) and 3 years (adjusted hazard ratio, 1.49; 95% confidence interval, 1.06–2.10).

Conclusion

A data-driven approach based on depressive symptoms identified five different depressive symptom profiles, including demoralization, in older patients with cancer. Severe depression was independently and substantially associated with poor survival.

Published: December 2018

Currently, treatment of small bowel adenocarcinoma (SBA) mirrors that of colorectal cancer (CRC). Recent genomic data have demonstrated SBA to be a genetically unique entity, suggesting that therapies not traditionally utilized in CRC should be explored. In order to further characterize the activity of taxanes in this rare cancer, we completed a single-center retrospective study. Twenty patients were found to have been treated with taxane-based regimens (monotherapy in 3, combination therapy in 17). Median time to progression was 3.8 months (95% confidence interval [CI] 2.9–4.6), and median overall survival was 10.7 months (95% CI: 3.1–18.3). The results of this study demonstrate clinical activity from taxane-based therapy in advanced SBA and support further clinical trial investigation.

Authors: ÖLMEZ HOSTA Hilal , ATA TUTKUN Nihal
Published: December 2018

Fen ve sosyal bilimlerde kullanılabilen yaşam modellerinde genellikle ilgilenilen sürecin sürekli olduğu varsayılmaktadır. Ancak böyle bir varsayım bazı yaşam verilerinin yapısına uygun olmadığından yaşam süreleri hatalı ölçülmekte ve kesikli yaşam süresi verileri için güvenilir olmayan sonuçlar elde edilmektedir. Sürekli veriler için kullanılan sürekli yaşam modelleri, sağlık bilimlerinde yer alan uygulamalardaki verilerin yapısını yansıtabilir. Fakat kesikli zaman verilerinin en çok kullanıldığı sosyal bilimler alanında, mevcut verilerin yapısı kesikli modellere daha uygun olduğu için özellikle bu alanda kesikli yaşam süresi modellerinin kullanımı daha yaygındır.

Bu çalışmada, kesikli yaşam süresi modelleri teorik açıdan incelenmiş ve Türkiye İstatistik Kurumu’ndan alınan “Türkiye'de Kadına Yönelik Aile İçi Şiddet Araştırması, 2008” verisine uygulanmıştır. Araştırmada yer alan kadınların evli kalma sürelerine etki eden faktörlerin incelenmesinde kesikli yaşam süresi modelleri kullanılmış ve sonuçlar yorumlanmıştır.

Nevşehir İli için Kızılırmak Nehri’nin İçme Suyu Potansiyelinin Araştırılması
Authors: ARAS Seval , FINDIK Özlem
Published: December 2018

Günümüz dünya nüfusunun artması doğal
kaynaklar üzerinde istenmeyen olumsuz bir baskı yaratmaktadır. Büyüyen
kentleşme ile beraber su talebinin artması, yeraltı su seviyesinin düşmesi, yapay
ve doğal su kütlelerinin yetersizliğine ve su kaynaklarımızın kalitesinin
düşmesine neden olmaktadır. Ülkemizdeki akarsular çoğu bölgede lağım, tarımdan
gelen çok miktarda gübre, kimyasal madde, sanayi ve iş yeri kaynaklı kirli
suların taşınması yoluyla alıcı ortam olarak kullanılmaktadır. İçme suyu elde
etmek için kullanılan doğal su kaynaklarımız da kirletici etkisinden dolayı
kalite bakımından düşmüştür. Suyun kendini temizleme sürecinde doğanın
üstlenebileceği bu kirlilikler zamanla yoğunlaşmıştır. İçme ve kullanma suyu olarak yüzeysel
suların (akarsular) kullanılmasından yola çıkılarak bu çalışma ile Kızılırmak
(Nevşehir İlinden geçen kısmı) Nehri’nin kullanım potansiyeli hakkında bilgi
edinmek amaçlanmıştır. Kızılırmak Nehri’nden bir yıl boyunca mevsimsel olarak
alınan su örneklerinde yapılan ölçümler ve analizler sonucunda amonyum 1.59
mg/l; bor 0.18 mg/l ve arsenik 0.014 mg/l ortalama değerler ile TS-266’ ya göre
yüksek olarak tespit edilirken; nitrit, nitrat, sülfat, alüminyum, civa,
kurşun, krom, nikel, bakır, kadmiyum ve mangan değerleri ise TS-266 sınır
değerleri arasında tespit edilmiştir. Elde edilen veriler doğrultusunda
Kızılırmak Nehri’nin mevcut kirleticilere yönelik uygun arıtma tekniklerinin
uygulanması ile içme ve kullanma suyu olarak kullanılabilirliği
öngörülmektedir.
