Biclustering and coclustering: concepts, algorithms and viability for text mining
Authors: Diaz Alexandra Katiuska Ramos , Peres Sarajane Marques
Published: August 2019

Biclustering and coclustering are data mining tasks capable of extracting relevant information from data by applying similarity criteria simultaneously to rows and columns of data matrices. Algorithms used to accomplish these tasks simultaneously cluster objects and attributes, enabling the discovery of biclusters or coclusters. Although similar, the natures and aims of these tasks are different, and coclustering can be seen as a generalization of biclustering. An accurate study on algorithms related to biclustering and coclustering is essential to achieve effectiveness when solving real-world problems. Determining the values appropriate for the parameters of these algorithms is even more difficult when complex real-world data are analyzed. For example, when biclustering or coclustering is applied to textual data (i.e., in text mining), a representation through a vector space model is required. Such representation usually generates vector spaces with a high number of dimensions and high sparsity, which influences the performance of many algorithms. This tutorial aims to didactically present concepts related to the biclustering and coclustering tasks and how two basic algorithms address these concepts. In addition, experiments are presented in data contexts with a high number of dimensions and high sparsity, represented by both a synthetic dataset and a corpus of real-world news. In general and comparative terms, the results obtained show the algorithm used for coclustering (i.e., NBVD) as the most appropriate for the experiments’ context. Although the biclustering algorithm (i.e., Cheng and Church) was responsible for producing less relevant results in textual data than NBVD, its application in data with a high number of dimensions and high sparsity provided a suitable study environment to understand its operation.
Customer-Base Concentration, Investment, and Profitability: The U.S. Government as a Major Customer
Authors: Cohen Daniel A. , Li Bin
Published: August 2019

We examine whether customer-base concentration has a differential impact on profitability for firms contracting with major government customers versus firms contracting with major corporate customers. We document that firm profitability increases with the concentration of major government customers, but decreases with the concentration of major corporate customers. We attribute the contrasting results to the differential impact of major government and corporate customers on demand uncertainty. Specifically, firms contracting with major government customers face lower demand uncertainty that enables them to realize more efficiency gains from customer-specific investments, whereas firms contracting with major corporate customers are exposed to higher demand uncertainty that reduces the efficiency of customer-specific investments. Overall, our study suggests that major government customers are unique and important in the composition of customer base, and they impact firm outcomes in a significantly different way than major corporate customers.

Laser material interaction parameter: New tool for developing property diagrams for welds
Authors: Barat Kaustav , Venkateswarlu K.
Published: August 2019

Detailed processing-property correlation studies have been attempted on laser beam welded AA 5024 (Al-Mg-Sc) alloys. These alloys are mostly used for integrally stiffened panels for aerospace applications. Different combinations of laser power, weld speed, beam diameter, and beam shape were chosen, and an optimized yield stress and uniform elongation map has been obtained. A comparative assessment of weld quality was done for the solid-state laser and the CO2 laser with two heat transfer modes, i.e., deep penetration (keyhole) and partial penetration (conduction) modes used for various aforementioned parameters. The weld parameters are ranked thereafter according to their merits and demerits encountered in this work. It has been seen that flexibility in terms of power, speed, and energy of a solid-state laser is more compared to the CO2 laser. Fundamental laser material interaction parameters have been studied, and an optimization strategy was formulated based on specific point energy of beam material interaction. The weld pool geometry has also been studied and correlated with interaction parameters. Weld size, shape, geometry, and evidence of solidification cracking have been studied from weld cross section macrographs. Variations of weld yield strength and elongation with welding energy input have been investigated thoroughly. Based on the above examinations, exaction of the optimal processing window is achieved.
COMPARATIVE MORPHOLOGICAL AND ANATOMICAL STUDIES ON Iris peshmeniana Güner & T. Hall. AND Iris aucheri (Baker) Sealy (IRIDACEAE)
Authors: KANDEMİR Nezahat
Published: August 2019

In this study, morphological and
anatomical features of two morphologically similar species (Iris peshmeniana Güner & T. Hall. and
Iris aucheri (Baker) Sealy) within
the Scorpiris Spach subgenus (Juno iris) of the genus Iris
L. were determined and similarities and differences between the two species
were discussed. Iris peshmeniana is endemic to Turkey and its spreading area is
protected because of exctinction threat. Iris
aucheri is not endemic to Turkey and it has a limited distribution in the
country. The cross-sections
from root, scape and leaves and surface-sections from leaves of species were
taken. Anatomical and morphological evaluations of the collected and obtained
samples revealed differences in plant size, leaf number, width and length, periant tube
length, fall length, standard structure, capsule length and width, bract and
bracteole structure, length of style branches and testa structure of seeds and
in the number of exoderma and cortex layers, margin structure of cortex
paranchyma cells, structure of the root center
cylinder, xylem strand number,
status micropapillae in lower epiderma, layer number of palisade and spongy
parenchyma and status of sclerenchyma cap. Although there were some differences
in morphological and anatomical features, based on similar anatomical and
morphological features revealed in the present study, it has been suggested
that I. peshmeniana may be a
subspecies of I. aucheri.

Community and family empowerment activities are classic activities that are currently still underestimated by many parties, but this is still relevant and urgent when linked to community service programs. This community service program is proven to have a direct impact on efforts to improve the quality of life of the community, especially for disadvantaged families or disadvantaged families. Through this paper, the authors raise several positive aspects that can be obtained from several stages of the implementation of community service conducted by Padang State University in Nagari Lubuk Jantan Tanah Datar Regency. The focus of the activity is the empowerment of pre-prosperous family economies through the utilization of family resources and yards. The election of Nagari Lubuk Jantan is based on the consideration that this area is relatively many target groups or communities that are still underdeveloped in various aspects of life, especially in the education aspects, social aspects, and cultural aspects, and low levels of welfare, while they have relatively large family members as well as large yards that are not used optimally. The results of these community service activities have a significant impact, including: increased public knowledge about family problems and potential, the community gets an understanding in increasing family income through the management of family resources, and skills in improving the family economy by choosing and cultivating plants of economic value in the yard around residential areas, especially for economically weak communities. It is expected that all parties, including universities, regional governments, the private world, and community leaders, can increase their awareness of the family empowerment program, especially in optimizing the utilization of the potential of family resources such as human resources, family assets and time. Therefore, in the future, a variety of scientific studies and a more comprehensive service program breakthrough and totality related to efforts to improve the quality of the family will lead to a more dignified prosperous family.Keywords: Family Resources, Disadvantaged Families, Yard

Authors: Hayder T. Assafli
Published: August 2019

The Quantum Dot Infrared Photo Detectors (QDIPs) become the leading technology in semiconductor detectors. This attraction comes from the properties of these devices that overpowers over the currently available detectors like Quantum Well Infrared Photo Detectors (QWIPs). In this paper, different Z-length dimensions are used to investigate the behavior of energy levels inside the quantum dots. The Z-length is also applied to investigate the shift of the operating wavelength and adjust the quantum dot performance by multiband Schroedinger-Poisson simulation. The generated electrons in the detection process are one of the most important properties of these dots. A software program is used to simulate the wave function, energy state, and absorption for different Z-dimensions. Results showed that the bandgap decreases and the absorption response shifts with increasing Z-dimension.

Published: August 2019

A Sufi has his own way (tariqah) in his spiritual journey. The difference of tariqah pursued by the Sufis creates schools of Sufism. However, one thing is mutually agreed that all the Sufi with various tariqah towards one goal, namely ma'rifatullah. This article will examine the process of achieving the Sufis in makrifatullah by passing comparative studies between one school with another. Through the analysis of some literature tasawuf researchers conclude that each Sufi has a distinctive tariqah in reaching the peak makrifatullah. In addition, all schools also have a tendency that the common tariqah that must be passed is the takhalli, tahalli and tajalli stages.

The three-way interplay of motor coordination, body fatness and physical activity in adolescents: a preliminary study
Authors: Chagas Daniel das Virgens , Batista Luiz Alberto
Published: August 2019

Study aim: The purposes of this study were to analyze: the influence of physical activity level on the association between motor coordination and body fatness; the influence of body fatness on the association between motor coordination and physical activity; and how much physical activity and body fatness, separately and together, explain motor coordination in adolescent boys.

Material and methods: Fifty-one boys (n = 51), aged between 12 and 14 years, participated in the study. Motor coordination and physical activity and body fat percentage were assessed with, respectively, the Körperkoordinationstest für Kinder (KTK) and a validated self-administered questionnaire (PAQ-C). Skinfold thickness was measured to assess the participant’s body fat percentage. The Kruskal-Wallis test was performed to compare levels of motor coordination, physical activity, and body fat according to age (12, 13, 14 years). Bivariate and partial correlations were used to analyze the interrelationships among the selected variables.

Results: In the total studied group (n = 51 boys), motor coordination was positively associated with physical activity level (r = 0.300) and negatively associated with body fatness (r = –0.297). However, these associations were not statistically significant (p > 0.05) when controlled for body fatness and physical activity, respectively. Also, body fat and physical activity together explained 11% of the variance in the motor coordination level in adolescent boys.

Conclusions: These findings suggest that body fatness can influence the association between motor coordination and physical activity as well as that physical activity level can influence the association between motor coordination and body fat percentage. Also, body fat and physical activity together, but not separately, partially explained the variance in the motor coordination level. Therefore, body fat and physical activity seem to be complementarily associated with motor coordination in adolescent boys.

Study aim: The aim of the present study was to compare the physiological responses of female soccer players recorded during the Beep Test and Yo-Yo Test.

Material and methods: Twenty-three high-level women’s soccer players underwent aerobic fitness testing. Modification of the Beep Test consisted of: lengthening the distance between turns to 40 m, extending the time between the increase in speed, and including a rest period between exercise stages. During the running efforts the length of the distance run in both tests was measured as well as circulatory and respiratory variables. For statistical analyses only data obtained at maximum loads in both tests were accepted.

Results: Analyzed variables showed that all values recorded in both tests reached maximum values and did not differ statistically significantly.

Conclusion: The results show that both applied tests loaded the soccer players to a similar maximum degree and the tests are suitable for assessing the aerobic physical performance.
In vitro interactions between Trichoderma harzianum and pathogenic fungi damaging horse-chestnut (Aesculus hippocastanum) leaves and fruits
Authors: Pastirčáková Katarína
Published: August 2019

Interactions between 3 pathogenic fungi damaging horse-chestnut (Aesculus hippocastanum) leaves and fruits – Phyllosticta sphaeropsoidea, Phomopsis carposchiza, and Diaporthe padi – and the antagonistic fungus Trichoderma harzianum were studied to determine their mutual influence in vitro. Antibiosis of colonies developing on 5 nutrient media was tested. The 3 studied T. harzianum isolates differed in their antagonistic potential. although T. harzianum isolates significantly inhibited the growth of Phomopsis carposchiza, the mycelium growth of some of the re-isolates on fresh medium indicates an inadequate antagonistic effect of T. harzianum on this species. The tested Trichoderma isolates showed stronger antagonism towards the other pathogens, reflected in overgrowing of Phyllosticta sphaeropso-idea and Diaporthe padi and reducing their growth. Granulation of the cytoplasm and lysis of hyphae of the fungal pathogens were the most frequently observed effects of the interaction.

Authors: Ślusarczyk Beata , Haseeb Muhammad , Hussain Hafezali Iqbal
Published: August 2019

The textile industry is one of the fastest growing industries which expressively contributes to the economic growth of Malaysia. However, in recent years, the situation has changed and demonstrates a downward trend. The imports are growing faster compared to the exports, consequently resulting in a low contribution to the gross domestic product (GDP). To address the issue, this study aims to investigate the role of Industry 4.0 on the performance of firms engaged in the production and services of the Malaysian textile industry. To achieve the objective, this study adopted a cross-sectional research design. A survey was carried out to collect data from employees of textile firms. Results of the study found that Industry 4.0 positively contributed to the effectiveness of the production and services of the textile industry. Production and services have a positive role in the performance of textile firms. The current study provides an interesting insight into the future direction of research for studies on organisational performance, which can be extended to different manufacturing-based industries. In addition, it provides the rationale for the adoption and implementation of smart technologies in these industries. It has been found that cyber-physical systems (CPS), interoperability, a smart city and a smart product have a positive effect on production and services. Additionally, it is not possible without the effective implementation of technology. Thus, the current study provides valuable insights into the improvement of the textile industry’s performance.
Aorto-mesenteric Bypass for the Treatment of Chronic Mesenteric Ischemia
Authors: Mocian Adriana , Russu Eliza , Kaller Reka , Mureșan Adrian
Published: August 2019

Chronic mesenteric artery disease has a much lower incidence than the acute one, but it raises the same problems in terms of patient survival. The long-term outcomes for open surgery are crucial for the right choice of a particular technique. We present the case of a 39-year-old female patient with a history of total nephrectomy, chronic kidney failure, and hypertension, who presented in the Emergency Department with abdominal pain with high intensity, for which she was admitted to the General Surgery Department. Abdominal computed tomography angiography was performed, which indicated the diagnosis of partial upper mesenteric artery stenosis. The patient underwent surgery, during which a retrograde aorto-mesenteric bypass with a Gore-Tex 5 mm diameter prosthesis was performed. In situations where the endovascular approach fails or has no indication (multiple incidence lesions from the origin of the superior mesenteric artery), open surgery is the indication in chronic mesenteric ischemia.
Factors Associated with Sub-intimal Coronary Artery Dissection in MINOCA Patients with Delayed Washout at Coronary Angiography – Protocol for an Observational, OCT-based Study
Authors: Parajkó Zsolt , Mester András , Păsăroiu Dan , Benedek Theodora , Benedek Imre
Published: August 2019

Background: Myocardial infarction (MI) with no obstructive coronary arteries (MINOCA) is a special form of the acute coronary syndrome. The heterogeneous pathophysiology of MINOCA is not well elucidated and includes cardiac and non-cardiac causes. Slow flow phenomenon on coronary angiography can be associated with several possible causes of MINOCA confirmed by optical coherence tomography (OCT). Therefore, the aim of this study is to assess the underlying mechanism of the delayed washout phenomenon on coronary angiography and the potential role of subintimal coronary artery dissection (SD) in the setting of an acute MI.

Methods and design: This clinical prospective, descriptive research will enroll patients diagnosed with acute MI (STEMI or NSTEMI) identified by coronary angiography, followed by OCT imaging of the coronary arteries at the Emergency Clinical County Hospital of Târgu Mureş, Romania. The enrolled patients will be separated into two groups based on OCT examination, patients with SD and patients with no SD.

Conclusion: The underlying mechanisms of MINOCA with delayed washout phenomenon on coronary angiography is still poorly understood. Modern invasive imaging techniques are capable to assess the microstructure of the coronary artery wall and are able to offer the much needed information to elucidate the pathophysiological changes which ultimately cause the acute event. The current study offers a new, complex – clinical, invasive and noninvasive imaging, as well as biomarker-based – approach, which may lead to a better understanding and treatment of this pathology.

Published: August 2019

A 15 year old female African lion (
Panthera leo
) was necropsied after its sudden death. The necropsy showed a mammary gland lesion measuring 10 cm in diameter and numerous white nodules with variable size in the liver, spleen, uterus, lungs and the heart. The histopathological examination showed that the neoplastic formation in the mammary region was a simple tubular carcinoma with metastases on the other organs. Upon immunohistochemical examination, the neoplastic cells expressed cytokeratins while the stroma of the tumour expressed vimentin. The proliferation index Ki-67 was moderate. Based on the macroscopic, histopathological and immunohistochemical findings, the neoplasia was diagnosed as a simple tubular mammary carcinoma.
Benefit of Wind Tunnels with Large Test Sections for Wind Engineering Applications
Authors: Flamand Olivier , Delpech Philippe , Palier Pierre , Bouchet Jean-Paul
Published: August 2019

Atmospheric Boundary layer wind tunnels (ABLWT) dedicated to building safety and comfort have been operated by CSTB in Nantes since 1971. Because ABLWT only deal with reduced scale models of real structures, the necessity of a larger wind tunnel, the Jules Verne Climatic wind tunnel (CWT), able to reproduce extreme wind loads on real scale structures arose in the years 80. Hence, it became a major European facility operating for improvement of the safety, quality and environmental impact of buildings and civil engineering works as well as products from industrial fields (transportation, energy…) with respect to strong winds and other climatic hazards. Both wind tunnel types, the ABLWT and the CWT are complementary and used for studying the effect of wind on the same structures at two different scales, when the effect of wind scaling is important. During the 2018 year, several modifications were made to the CWT facility. The atmospheric test section of the existing facility was elongated preserving the initial advantages, very large test section (approximately 120 m2) with wind velocity performance compatible with many applications (up to 90 km/h). This new test section makes it possible to simulate turbulent wind and driving rain testing. The sand winds capabilities have been maintained in the new design, despite the closed loop configuration, by fitting a filtering. The modifications of the wind tunnel geometry now offer a long test section upstream the turning vanes where a whole set of new tests can be carried out, as windmill field, natural ventilation of urban environments, slender structures (large bridges, pylons, cable transport systems,)
On the Use of the Cubic Translation to Model Bimodal Wind Pressures
Authors: Rigo François , Andrianne Thomas , Denoël Vincent
Published: August 2019

The cubic translation model is a well know tool in wind engineering, which provides a mathematical description of a non-Gaussian pressure as a cubic transformation of a Gaussian process. This simple model is widely used in practice since it offers a direct evaluation of the peak factors as a function of the statistics of the wind pressure data. This transformation is rather versatile but limited to processes which are said to be in the monotonic region. For processes falling outside this domain, this paper describes an alternative which is based on the physics of the wind flow. First, it is shown, with a classical example of a flow involving corner vortices on a flat roof, that the pressure data which does not meet the monotonic criterion is in fact associated with a bimodal distribution. Then, the proposed approach is to decompose this data into the two governing modes (slow background turbulence and fast corner vortices) and apply the usual translation model to each of them.

Authors: Firănescu Adela-Gabriela , Moța Maria
Published: August 2019

Background and aims:Diabetes mellitus (DM) is a risk factor for pulmonary tuberculosis (TB), increasing the risk of progression of latent tuberculosis infection (LTBI) to active TB threefold, threatening the TB control, especially in developing countries. The aim of this study was to assess active and latent TB infection frequency in patients with DM.

Material and methods:There were enrolled in this study 503 adult DM patients. Active TB screening was performed through anamnestic data, clinical examination and chest X-ray and latent TB infection screening was evaluated using the tuberculin skin tests (TST).

Results:A number of 63 (12.5%) patients had type 1 DM and 440 (87.5%) had type 2 DM. Personal history of TB was present in 21 (4.2%) subjects, 5 (8.1%) with type 1 DM and 16 (3.6%) with type 2 DM. The TST was positive in 258 (51.5%) patients and 54 (10.7%) presented cough for more than two weeks at the time of examination. The chest X-ray revealed suggestive lesions for active TB in 4 (1%) subjects and lesions of inactive TB in 90 (22.4%) subjects.

Conclusions:TB screening must receive proper attention in patients with DM, being essential for diagnosis in those with nonspecific symptoms.

Published: August 2019

Background and aims: Leucine, Isoleucine, and Valine collectively known as Branched-chain amino acids (BCAAs), can be closely associated with metabolic dysregulates and with insulin resistance. We aimed to explore the role of BCAAs as potential treatment option for diabetes.

Material and method: Bioassay the effect of BCAAs on MIN6 cell line on insulin secretion and pancreatic beta cells expansion, then were checked for inhibitory potential of pancreatic amylase, glucosidase and lipase as alternative approach for diabetes treatment.

Results: BCAAs significantly enhance insulin secretion parallel to L-alanine efficacy. Furthermore, BCAAs obtain a dose dependent β-cell proliferation similar to glucagon-like peptide-1. Moreover, these acids could restore the secretory function of MIN6 β-cell despite stressful gluco-lipo-toxicity; separately or combined. Moreover, BCAAs exerted a dose dependent dual inhibition of amylase, glucosidase and lipase.

Conclusions: Our current findings suggest that BCAAs supplementation may have a potential therapeutic effect against diabetes as insulin releasing agent and as specific inhibitors for both-amylase/α-amyloglucoside and lipase

Published: August 2019

Polymer-based matrix composite materials are in high demand in many different fields: aeronautics, pressure vessel manufacturing, wind turbine blade manufacturing, and others. Due to the great mechanical properties of fiber reinforced plastics, it is a desirable material for various applications, but at the same time its heterogenic structure makes the composite waste hard to recycle. This paper focuses on different fiber reinforced plastics (FRP) waste recycling methods and their comparison by carrying out literature review and using multi-criteria decision making analysis (MCDA). Four polymer matrix composite waste recycling methods are compared to calculate which one has the best sustainability performance based on the chosen criteria. Analytical Hierarchy Process and TOPSIS are applied for criteria weighing and method comparison. Sensitivity analysis is used to evaluate the obtained results. It is concluded that more studies concerning different FRP waste recycling method sustainability performance need to be done, to derive more data, that would make MCDA more reliable and also other FRP waste recycling methods could be compared. Another conclusion is that different methods have different strengths which makes it hard to compare them. While FRP waste recycling is getting more broadly used, there still is a lot of work to establish wide spread effective system of FRP waste recycling that is both economically viable and gives the best results concerning recycled material quality.
Measurement and Prediction of Density and Viscosity of Different Diesel-Vegetable Oil Binary Blends
Authors: Gulum Mert , Bilgin Atilla
Published: August 2019

Vegetable oils can be considered as an alternative or emergency fuel for diesel engine. However, vegetable oils result in operational and durability problems for the long-term operation because of being much more viscous than diesel fuel. To eliminate this drawback, blending of vegetable oils with diesel fuel or alcohol is one of the most widely used techniques. In the existing literature, many studies are available on the measurement and prediction of density and viscosity of binary blends (especially biodiesel (BD)-diesel fuel (DF) blends), although, there is still the lack of comprehensive studies in which reliable density and viscosity data are presented, new regression models are proposed and compared with other regression models for waste cooking oil (WCO)-DF binary blends. Therefore, in the present study, (1) WCO was blended with DF on the volume basis of 2, 4, 6, 8, 10, 15 and 20 %, (2) the measurements of viscosities and densities of the binary blends were performed at various temperatures (278.15–343.15 K) in accordance with DIN 53015 and ISO 4787 standards, respectively, (3) the variations of viscosity and density values of binary blends vs. temperature were evaluated, (4) the new rational and exponential models as a function of temperature were fitted to the experimental data measured by the authors and Baroutian et al. (regarded as typically different data), and finally (5) the models were also compared to Yoon et al. and linear models, previously proposed by other authors, in order to investigate their reliability. According to results, (i) the best correlation was obtained by the rational model with the lowest maximum relative errors of 2.9679 % and 3.2725 % for the viscosity data measured by the authors (WCO-DF blends) and Baroutian et al. (palm oil (PO)-DF blends), and (ii) for the density data of WCO-DF and PO-DF binary blends, the best correlation was obtained using the exponential model giving the lowest maximum relative errors of 0.0470 % and 0.0581 %, respectively.

Authors: Kuśmierek Natalia , Pyrka Ewa , Popiołek Marcin
Published: August 2019

The purpose of this review was to summarise the current species richness of helminths in the reptiles from Poland and to provide a host-parasite list along with studied localities. Between 1926 and 2018 the occurrence of at least 37 taxa of helminths were observed; of these, 19 belong to Trematoda, 14 to Nematoda, two to Cestoda, and two to Acanthocephala. In total, reports of 642 specimens of reptiles from 15 locations were included in this review, namely: 166 Natrix natrix (10 locations), 159 Vipera berus (6), 155 Lacerta agilis (6), 107 Zootoca vivipara (5), 52 Anguis fragilis sensu lato (4), and 3 Zamenis longissimus (1). The highest species richness of internal parasites was observed in N. natrix (at least 26 helminth taxa) and V. berus (20). Two out of nine species of reptiles, Coronella austriaca and Emys orbicularis, have not yet formed part of any helminthological surveys in Poland. To date, research conducted on helminths infecting reptiles has primarily been throughout eastern Poland. Over 60% of studied reptiles were caught in the Bieszczady Mts. or in Warsaw and its surroundings. Based on the current review, future research should focus on host species for which intestinal parasite data are poorly known i.e. E. orbicularis, Z. longissimus, C. austriaca. In general surveys should also expand into the western part of the country. Additionally, interspecies differences between two cryptic species of slow worms, Anguis fragilis and A. colchica, would provide interesting data on parasite host specificity.

The aim of the present work was to investigate and compare the content of phenolic compounds in four taxa of Erigeron acris L. s. l.: E. acris (EAA), E. acris subsp. droebachiensis (O.F. Müll.) Arcang. (EAD), E. acris subsp. serotinus (Weihe) Greuter (EAS) and E. ×huelsenii Vatke (EH), a hybrid between E. acris and E. canadensis L. The total flavonoid content was determined by Christ-Müller method and the total phenolic acid content was determined by the method utilizing Arnov’s reagent. The method using ultra high performance liquid chromatography with photodiode array detection (UHPLC-PDA) was applied for the separation, identification and quantification of nine phenolic compounds (protocatechuic acid, chlorogenic acid, caffeic acid, 6′-O-caffeoylerigeroside, scutellarein-7-O-β-D-glucuronide, quercetin 3-O-glucoside, 4,5-dicaffeoylquinic acid, quercetin and luteolin) in the aerial parts of E. acris s. l. The chromatographic separation was carried out using a BEH C18 column packed with 1.7-μm particles and gradient elution with a mobile phase of water and methanol, both containing 0.02% (v/v) trifluoroacetic acid. The four investigated taxa of E. acris s. l. differed in the composition and the content of phenolic compounds. The main substances determined in the methanolic herbal extracts were: scutellarein-7-O-β-D-glucuronide (EAA, EAS, EAD and EH), 6′-O-caffeoylerigeroside (EAA, EAD and EH) and chlorogenic acid (EAS and EH). Moreover, the results indicated that five of the nine tested compounds were found in all investigated extracts from herbs of E. acris s. l. Two of them (6′-O-caffeoylerigeroside and scutellarein-7-O-β-D-glucuronide) could be selected as potential chemotaxonomic markers of the genus Erigeron L.

Allergic conjunctivitis (AC), defined by ocular itching, hyperemia, lacrimation and edema, impairs the quality of life across the globe. Ebastine is available as an oral antihistamine formula, such as tablets and syrup, for allergic disorders. Topical antihistamines are preferred over oral agents since their direct application at the site of action results in rapid onset and superior efficacy with less systemic side effects. The objective of the present work was to evaluate the antiallergic potential of optimized ebastine (1% w/v) colloidal ocular formulation by performing in vitro study like hen's egg chorioallantoic membrane test (HET-CAM) for tolerability and in vivo efficacy study in ovalbumin (OA)-induced allergic conjunctivitis (AC) with acute ocular irritation study. Eye scratching behavior and edema were evaluated after topical antigen challenge. Edema was scored at periodic interval after the instillation of ovalbumin followed by histopathology. The results showed that ebastine (1% w/v) colloidal ocular formulation was effective in inhibiting symptoms of eye inflammation induced by ovalbumin. Further, the study indicated that said formulation has a quick onset and the duration of effect sufficient to provide relief from symptoms for 24 hr. Ocular irritation by HET-CAM assay showed that the developed formulation does not cause any irritation to the blood vessels. Acute ocular irritation test was performed using rabbits and results showed that developed formulation was non-irritant to the eye. The present study revealed that the ocular ebastine formulation could offer a novel therapeutic opportunity against IgE-mediated allergic conjunctivitis.

Authors: Kothai S. , Umamaheswari R
Published: August 2019

Microsponges become imperative in the field of targeted drug delivery and in other biomedical applications. There was a clamant need for designing microsponges incorporating with green synthesised metal nanoparticles rather than the chemical drug in order to reduce the side effects of the drug and thus increasing the effectiveness of nature of the whole material. It provokes us to design this novel approach of loading copper nanoparticles into the microsponges. Here in this work, microsponges based on ethyl cellulose and polyvinyl alcohol were synthesised by Quasi-Emulsion Solvent diffusion method in which copper nanoparticles procured from Hibiscus rosa-sinensis leaf extract was incorporated. The Loaded microsponges were characterised by High Resolution Scanning Electron Microscopy (HR-SEM) and Particle size distribution Analyzer (PSA). The Drug content and Entrapment Efficiency of the microsponges were found out. The antimicrobial and antioxidant activity of the loaded microsponges were evaluated.

Mengetahui karakteristik dan tipe urban sprawl digunakan analisis deskriptif dengan pendekatan spasial dan untuk tingkat urban sprawl dilakukan dengan pemberian  scoring pada variable urban sprawl. Hasil penelitian menunujukkan bahwa karakteristik urban sprawl dicirikan dengan penggunaan lahan terpisah yang terletak jauh dari pusat-pusat permukiman, kepadatan penduduk rendah sekitar 4.499 jiwa/km2,  penggunaan mobil pribadi yang tinggi pada jam sibuk yakni sebesar 5.945 unit setiap hari.  Tipe urban sprawl yang dominan adalah perembetan memanjang dan perembetan meloncat terjadi pada jalan arteri maupun kolektor, sedangkan perembetan meloncat terjadi di beberapa kelurahan. Kelurahan Delima dan Kelurahan Tuah Karya termasuk pada tipologi ke-1 dengan tingkat urban sprawl rendah, dan tipologi ke-2 dengan tingkat urban sprawl sedang terjadi di Kelurahan Sidomulyo Barat, sedangkan Kelurahan Simpang Baru termasuk pada  tipologi ke-3 dengan tingkat urban sprawl tinggi.

[EN] This study aims to determine the characteristics, typology, and levels of urban sprawl that occur in the city of Pekanbaru. The study sample numbered 99 out of 7,646 numbers of digitalized buildings. Knowing the characteristics and types of urban sprawl used descriptive analysis with a spatial approach and for the level of urban sprawl carried out by giving scoring to urban sprawl variables. The results of the study show that the characteristics of urban sprawl are characterized by separate land uses located far from residential centers, low population density of around 4,499 people / km2, high private car use during peak hours which is 5,945 units per day. The dominant type of urban sprawl is longitudinal infiltration and jumping leaks that occur on arterial roads and collectors, while leachates jump in several villages. The Delima and Tuah Karya Villages included in the 1st typology with a low level of urban sprawl, and the second typology with the level of urban sprawl was occurring in Sidomulyo Barat Village, while the Simpang Baru Village was included in the 3rd typology with high urban sprawl.
