Large impact of tiny model domain shifts for the Pentecost 2014
MCS over Germany
Authors: Barthlott Christian , Barrett Andrew I.
Published: September 2019

Abstract. The mesoscale convective system (MCS) that affected Germany at Pentecost 2014 (9 June 2014) was one of the most severe for decades. However, the predictability of this system was very low as the operational deterministic and ensemble prediction systems failed to predict the event with sufficiently long lead times. We present hindcasts of the event using the COnsortium for Small-scale MOdeling (COSMO) model at convection-permitting (2.8 km) resolution on a large (1668 × 1807 km) grid, which allowed us to simulate the whole life cycle of the system originating from the French Atlantic coast. Results show that this model configuration successfully reproduces the convective events of that day. However, the low predictability of the event was evident by the surprisingly large impact of tiny changes to the model domain. We systematically shifted the model domain by one grid point in eight different directions, from which three did not simulate any convection over Germany. The analyses show that no important differences in domain-averaged initial conditions nor in the preconvective environment ahead of the convective system exist. That one-third of these seemingly identical initial conditions fails to produce any convection over Germany is intriguing. The main reason for the different model results seems to be the proximity of the track of the initial convective system to the coast and colder sea surface. The COSMO model simulates small horizontal displacements of the precursors of the MCS which then determine if the cells dissipate close to the sea or reach a favourable area for convective development over land and further evolve into an MCS. This study demonstrates the potentially huge impact of tiny model domain shifts on forecasting convective processes in this case, which suggests that the inclusion of this simple method in convective-scale ensemble forecasting systems should be evaluated for different cases, models and weather regimes.

A Street for All? Pluralism and the Performing Arts inJalan Sesama(IndonesianSesame Street)
Authors: Clendinning Elizabeth
Published: September 2019

This article examines traditional Indonesian performing arts scenes used in the Indonesian television program Jalan Sesama (the local version of American Sesame Street) as a means of teaching children across the nation about the country’s cultural diversity. I use close analyses of five geographically disparate regional art forms portrayed in the program to explore how their depictions reveal tensions between traditional performing arts and mass media, regionalism and nationalism, and religiousness and secularism in Indonesia. I argue that such portrayals supplant the pedagogical lessons inherent in the original art forms, replacing them with a more homogeneous appreciation of cultural diversity as a national civic good.

Abstrak. Artikel ini membahas pengunaan seni pertunjukan tradisional Indonesia yang digunakan di dalam program televisi Jalan Sesama (versi Indonesia program Sesame Street di Amerika) sebagai sarana untuk mengajar anak-anak di seluruh Indonesia tentang keragaman budaya negara itu. Saya menganalisa lima jenis seni pertunjukan dari berbagai daerah yang ditampilkan dalam program untuk menjelajahi bagaimana mereka mengungkapkan ketegangan di antara seni pertunjukan tradisional dan media massa, secara kedaerahan maupun secara nasional, maupun keagamaan dan diluar agama di Indonesia. Saya berpendapat bahwa hal seperti ini mengubah pelajaran pedagogis yang melekat dalam seni asli dan menggantikannya dengan apresiasi lebih umum tentang keragaman budaya sebagai masyarakat nasional.
Toward a Humanist Approach to Historic Preservation
Authors: Heath Kingston Wm.
Published: September 2019

This essay is an attempt to describe a humanist approach to historic preservation that has evolved over a research and teaching career begun in 1976. It addresses how that approach has been manifested in my own work and in some of the work of my students and colleagues. The humanist approach discussed herein seeks to demonstrate how tracing layers of cultural development informs the public about environmental and human intervention over time. It also seeks to tell complete, interwoven histories that inform us about diverse identities in the process of placemaking.

Scaled Pearson’s Correlation Coefficient for Evaluating Text Similarity Measures
Authors: Atoum Issa
Published: September 2019

Despite the ever-increasing interest in the field of text similarity methods, the development of adequate text similarity methods is lagging. Some methods are decent in entailment while others are reasonable to the degree to which two texts are similar. Very often, these methods are compared using Pearson’s correlation; however, Pearson’s correlation is bound to outliers that could affect the final correlation coefficient figure. As a result, the Pearson correlation is inadequate to find which text similarity method is better in situations where data items are very similar or are unrelated. This paper borrows the scaled Pearson correlation from the finance domain and builds a metric that can evaluate the performance of similarity methods over cross-sectional datasets. Results showed that the new metric is fine-grained with the benchmark dataset scores range as a promising alternative to Pearson’s correlation. Moreover, extrinsic results from the application of the System Usability Scale (SUS) questionnaire on the scaled Pearson correlation revealed that the proposed metric is attaining attention from scholars which implicate its usage in the academia.
Physical activity in type 1 diabetic young and early adults treated with insulin pump therapy. A preliminary report.
Authors: Roszkowski A. , Kulesza K. , Cybulski M. , Witkowska A.M.
Published: September 2019

Purpose: To determine the level of physical activity in young and early adults with type 1 diabetes in comparison with their healthy counterparts and to determine whether the use of insulin pump facilitates physical activity.
Materials and methods: This study included 40 type 1 diabetes (T1D) subjects of both sexes treated with a personal insulin pump therapy, and 30 healthy controls. The diagnostic survey included questions about nutrition, knowledge about the disease and whether the patient can control diabetes through physical activity, diet and self-monitoring. The International Physical Activity Questionnaire – long form (IPAQ-L), was used to assess the level of physical activity of both diabetic and control individuals.
Results: 87.5% T1D subjects believe that using an insulin pump facilitates their physical activity. The level of physical activity associated with cycling (p=0.038) and vigorous physical activity (p=0.008) was higher in T1D than in the control group. Statistically significant differences (p=0.043) were found for total physical activity. The total mean activity was higher in participants with T1D (8147.70 MET-min/week) compared to the control group (5857.55 MET-min/week).
Conclusions: Young and early adults with type 1 diabetes may be more physically active than their healthy counterparts, mainly in their leisure time. The use of a personal insulin pump facilitates physical activity, but most diabetics experience episodes of hypoglycemia after physical activity.

Authors: Łaguna W. , Bagińska J. , Oniśko A.
Published: September 2019

Purpose - The aim of this study was to use probabilistic graphical models to determine dental caries risk factors in three-year-old children. The analysis was conducted on the basis of the questionnaire data and resulted in building probabilistic graphical models to investigate dependencies among the features gathered in the surveys on dental caries.
Materials and Methods - The data available in this analysis came from dental examinations conducted in children and from a questionnaire survey of their parents or guardians. The data represented 255 children aged between 36 and 48 months. Self-administered questionnaires contained 34 questions of socioeconomic and medical nature such as nutritional habits, wealth, or the level of education. The data included also the results of oral examination by a dentist. We applied the Bayesian network modeling to construct a model by learning it from the collected data. The process of Bayesian network model building was assisted by a dental expert.
Results - The model allows to identify probabilistic relationships among the variables and to indicate the most significant risk factors of dental caries in three-year-old children. The Bayesian network model analysis illustrates that cleaning teeth and falling asleep with a bottle are the most significant risk factors of dental caries development in three-year-old children, whereas socioeconomic factors have no significant impact on the condition of teeth.
Conclusions - Our analysis results suggest that dietary and oral hygiene habits have the most significant impact on the occurrence of dental caries in three-year-olds.
Altered communication in Parkinson’s disease, its role in stigmatisation of the condition and effect on social relationships
Authors: Polityńska B. , Pokorska O. , Łukaszyk-Spryszak A. , Kowalewicz A.
Published: September 2019

Communication difficulties in Parkinson’s disease (PD) arise not only as the result of the motor symptoms of the disorder, but also as a consequence of cognitive and affective impairments which are recognised as being part of the disease process. These changes are thought to account for much of the stigma associated with the condition, thereby complicating the ability of patients to inter-relate with others, including their closest family. This inevitably affects quality of life for both the patient and those family members involved in his/her care.
The present paper presents an analysis of how the deficits in motor and cognitive function associated with PD in the form of reduced facial expressivity, altered language skills, motor and cognitive slowness and disturbances in the pragmatic aspects of language affect the communication abilities of patients with the disorder and give rise to stigmatisation, which in turn impacts the disability seen in PD.

Oxide crystals on the surface of porous
indium phosphide
Authors: Suchikova Y.O. , Bogdanov I.T. , Kovachov S.S.
Published: September 2019

Purpose: f this paper is to is to establish the patterns of oxide formation on the surface of
indium phosphide during electrochemical etching of mono-InP.
Design/methodology/approach: A porous surface was formed with the anode electrolytic
etching. Morphology of the surface was studied with the help of scanning electron
microscope JSM-6490. The analysis of chemical composition of porous surface of samples
was also performed.
Findings: It was shown that during the electrochemical etching of indium phosphide, oxide
films and crystallites form on the surface. It has been established that crystalline oxides
are formed mainly on the surface of n-type indium phosphide. Continuous oxide films are
predominantly formed on the surface of p-InP.
Research limitations/implications: The research was carried out for indium phosphide
samples synthesized in the solution of hydrofluoric acid, though, carrying out of similar
experiments for crystalline oxides on the surface of porous indium phosphide obtained in
other conditions, is necessary.
Practical implications: The study of oxide crystals on the surface of porous indium
phosphide has great practical importance since it is the reproducibility of experimental
results that is the main problem of modern materials science, the more nanoengineering.
Oxides can significantly affect the properties of materials. On the one hand, oxides
significantly affect the recombination properties of materials, this can impair the operation
of semiconductor devices. On the other hand, oxide films can serve as a passivating
coating for the surface of a porous semiconductor. Such an oxide property will be useful for
the practical application of nanostructured indium phosphide. Therefore, questions of the
conditions for the formation of semiconductor intrinsic oxides, their structure, and chemical
composition, and also the effect of oxides on the physical and technical characteristics of
materials are important.
Originality/value: The patterns of oxide formation on the surface of indium phosphide
during electrochemical etching are investigated in this work. It is shown for the first time that
the structure of an oxide depends on the orientation of the surface of the semiconductor.
It was shown that continuous oxide films are formed on the surface of p-InP, and oxide
crystalline clusters are formed on the surface of n-InP.

nitrogen steel at dry and solid state
lubricants assistant friction
Authors: Balitskii O.A. , Kolesnikov V.O. , Balitskii A.I.
Published: September 2019

Purpose: This paper is devoted the investigation hydrogen influence on of wear resistance
of high nitrogen steel (HNS) at dry and solid state lubricants assistant friction. It has been
established that after hydrogenation at 250 N loading the wear rate increased by 2.9 ...
4.1 times. Microhardness of hydrogenated layer was 7.6 ... 8.2 GPa, that is increased after
hydrogenation in two times. After adding the (GaSe)xIn1-x compounds to the tribo conjugates
by X-ray diffraction analysis it has been established the appearance of new phases which
formed during the friction process and detected on the friction surface.
Design/methodology/approach: This work presents research results concerning the
comparative tests of high nitrogen steels in the circumstances of dry rolling friction. It was
conducted the experiments to determine the tribological properties of high-nitrogen steels
under rolling friction. The test pieces were manufactured in the form of rollers, and rotated
with a linear velocity 2.27 m/s (upper roller), 3.08 m/s (bottom roller). Upper roller is made
from HNS was subjected for hydrogenation. Analysis of friction surfaces indicates the
complex mechanism of fracture surfaces. The results of the local X-ray analysis and X-ray
diffraction analysis has been established the appearance of new phases and elements on
the friction surface.
Findings: It has been found that the level of wear resistance of the investigated materials
under hydrogenation. Compounds realize chemisorption, tribochemical mechanisms of the
formation of thin protective (anti-wear, antifriction) layers on metal surfaces.
Research limitations/implications: An essential problem is the verification of the
results obtained using the standard mechanical tests, computer-based image analysis and
other methods.
Practical implications: The observed phenomena can be regarded as the basic
explanation of reduces the plasticity characteristics after hydrogenation. Applying the
(GaSe)xIn1-x compounds as a lubricant will allow the formation of films on friction surfaces
that can minimize surface wear, which will contribute to the transition to a wear-free friction
mode. The protective film is a barrier to high shear and normal loads, preserving the base
metal of the part and providing reduced wear and friction.
Originality/value: The value of this work is that conducted experiments permit to determine
the tribological properties of high nitrogen steels under rolling friction after hydrogenation.
After adding (GaSe)xIn1-x compounds to the tribo conjugates after due to X-ray diffraction
analysis it has been established the appearance of new phases which formed during the
friction process and detected on the friction surface.

Authors: Baqiya Malik Anjelh , Lailiyah Qudsiyyatul , Riyanto Agus , Arifin Zaenal , Triwikantoro  , Zainuri Mochamad , Pratapa Suminar , Darminto
Published: September 2019

This article aims to report on the production of precipitated CaCO3, with various morphologies and particle sizes through several methods, namely carbonation methods with CO2 gas bubbling, rapid mixing of the solutions, and carbonation with modified bubbling techniques. The simple bubbling method was performed by flowing CO2 gas into Ca(OH)2 solution until precipitation occurs. This method can produce calcite particles up to 100% at the intermediate temperatures. In the modified bubbling technique, the gas flow was interrupted by a breaker and porous material with variation of stirring speeds. Through this technique, it produces 99% aragonite particles at higher temperatures. Additionally, 95% spherically vaterite particles with porous structures can also be produced by the rapid mixing solution method at the low temperatures. Depending on the reaction temperature, pH and concentration of the solution, and CO2 gas flow rate, these methods provide alternative routes for producing precipitated CaCO3 particles from natural limestone extraction with certain morphology and particle size for additional applications.
Comparison of oral capecitabine alone versus platinum combinations in elderly metastatic gastric cancer patients
Authors: DEĞİRMENCİOĞLU Serkan , ÜNAL Olçun Ümit , OKTAY Esin
Published: September 2019

Background: Gastric cancer is responsible for a considerable
proportion of all cancer-related deaths. Elderly cancer patients are often
ignored in prospective studies in which the efficacy of chemotherapy is
evaluated, although more than half of all gastric cancer cases are over the age
of 70 years. The present study aims to evaluate the efficacy and feasibility of
capecitabine-based chemotherapies in geriatric patients with gastric cancer. Methods: A total of 81 patients over
the age of 65 years who received chemotherapy for metastatic gastric cancer at
two oncology centers between 2012 and 2017 were included in the study. The
medical records of the patients were evaluated retrospectively, and the
patients and their performance status were evaluated using the American Joint
Committee on Cancer staging system and the World Health Organisation scale,
respectively. Results: The mean age was 74 years. The
male gender and the adenocarcinoma histological type were seen in higher rates.
Most of the patients underwent capecitabine-cisplatin chemotherapy, and the
mean follow-up was 42 months. The median overall survival of the groups of
patients receiving capecitabine-cisplatin, capecitabine-oxaliplatin and
capecitabine was 8 months, 10.7 months and 8.9 months, respectively, indicating
no statistically significant differences between the groups (p=0.467). The
median overall survival of all patients was found to be 8.7. The
progression-free survival between the different chemotherapy subgroups was not
statistically significant (p=0.59). The most common side effect was found to be
anemia. Grade 3–4 adverse effects were similar between the arms of the study
(p=0.725). A statistically significant increase was found in the mortality risk
with an increased number of metastatic sites in a multivariate analysis
(p=0.001). No correlation was found between the chemotherapy protocols and
mortality risk (p=0.472). Adverse effects such as stomatitis, nausea/vomiting,
neuropathy, neutropenic fever and nephrotoxicity, independent of chemotherapy,
were statistically and significantly associated with the mortality risk
(p=0.045, p=0.047, p=0.036, p=0.02 and p=0.049, respectively).

Conclusions: Our study results
show that adverse effects such as stomatitis, nausea/vomiting, neutropenic
fever, nephrotoxicity and neuropathy increase the mortality risk which suggest
that particularly oral health care, the application of appropriate antiemetic
treatments, the close follow-up of kidney function tests and adequate
hydration, protective infection barrier measures and effective treatment of
neuropathy associated with chronic diseases are as important as chemotherapy in
geriatric cases.
Ratiocentrism, Intrinsic Value, and the Moral Status of the Nonhuman Natural World
Authors: Ezedike Edward Uzoma ,   Center for Environmental Philosophy, The University of North Texas
Published: September 2019

Kant’s doctrine of the “categorical imperative” with respect to ratiocentrism needs to be examined for its implications for environmental ethics. Kant’s argument is that moral actions must be categorical or unqualified imperatives that reflect the sovereignty of moral obligations that all rational moral agents could figure out by virtue of their rationality. For Kant, humans have no direct moral obligations to non-rational, nonhuman nature: only rational beings, i.e., humans, are worthy of moral consideration. I argue that this position is excessively anthropocentric and ratiocentric in excluding the nonhuman natural world from moral consideration. While conceding that nonhuman nature is instrumentally valuable owing to some inevitable existential, ontological considerations, moral obligation should be extended to the natural world in order to achieve environmental wholeness.

Published: September 2019

Dans le contexte actuel de surpoids et d’obésité, de nombreuses communautés en ligne de soutien à la perte de poids ont vu le jour ces dernières années sur Internet. Leur effet sur le comportement des utilisateurs a été peu étudié. A l’aide de deux études qualitatives menées auprès d’experts en nutrition et d’utilisateurs de communautés en ligne de soutien à la perte de poids, cette recherche met en avant la comparaison sociale et l’influence sociale qui s’exercent au sein de ces communautés. Les résultats montrent notamment 1/ que l’influence sociale en ligne dans ces communautés est de nature informationnelle plutôt que normative, 2/ que parfois, les utilisateurs peuvent être enclins à adopter des choix alimentaires restrictifs sur la base des pratiques et conseils d’autres membres et 3/ que les utilisateurs peuvent être influencés à la suite de comparaisons sociales avec les membres de la communauté, ces comparaisons étant principalement ascendantes (avec un standard jugé supérieur) mais également, descendantes (avec un standard inférieur) et latérales (avec un standard similaire). Les individus peuvent également se comparer à eux-mêmes dans le passé (comparaison temporelle).
Recherche d’images dans les bibliothèques numériques patrimoniales et expérimentation de techniques d’apprentissage profond
Authors: Moreux Jean-Philippe
Published: September 2019

Si historiquement, les bibliothèques numériques patrimoniales furent d’abord alimentées par des images, elles profitèrent rapidement de la technologie OCR pour indexer les collections imprimées afin d’améliorer le service de recherche d’information offert aux utilisateurs. Mais l’accès aux ressources iconographiques n’a pas connu les mêmes progrès et ces dernières demeurent dans l’ombre : indexation manuelle lacunaire, hétérogène et impossible à généraliser ; silos par genre documentaire ; recherche dans le contenu des images encore peu opérationnelle sur les collections patrimoniales. Aujourd’hui, il serait pourtant possible de mieux valoriser ces ressources en exploitant les énormes volumes d’OCR produits durant les deux dernières décennies (tant comme descripteur textuel que pour l’identification automatique des illustrations des imprimés), en profitant de la maturité des techniques d’intelligence artificielle (en particulier l’apprentissage profond ou deep learning), pour mettre ainsi en valeur ces gravures, dessins, photographies, cartes, etc., pour leur valeur propre, mais aussi comme point d’entrée dans les collections, en favorisant découverte et rebond.

Cet article décrit une approche ETL (extract-transform-load) appliquée aux images d’une bibliothèque numérique à vocation encyclopédique : identifier et extraire l’iconographie partout où elle se trouve (dans les collections d’images, mais aussi dans les imprimés) ; transformer, harmoniser et enrichir ses métadonnées descriptives grâce à l’IA ; intégrer ces données dans une application web dédiée à la recherche iconographique. Cette approche est qualifiée de pragmatique à double titre, puisqu’il s’agit de valoriser des ressources numériques existantes tout en mettant à profit les acquis de l’IA.

From habitat use to social behavior: natural history of a voiceless poison frog, Dendrobates tinctorius
Authors: Rojas Bibiana , Pašukonis Andrius
Published: September 2019

Descriptive studies of natural history have always been a source of knowledge on which experimental work and scientific progress rely. Poison frogs are a well-studied group of small Neotropical frogs with diverse parental behaviors, distinct calls, and bright colors that warn predators about their toxicity; and a showcase of advances in fundamental biology through natural history observations. The dyeing poison frog, Dendrobates tinctorius, is emblematic of the Guianas region, widespread in the pet trade, and increasingly popular in research. This species shows several unusual behaviors, such as the lack of advertisement calls and the aggregation around tree-fall gaps, which remain poorly described and understood. Here, we summarize our observations from a natural population of D. tinctorius in French Guiana collected over various field trips between 2009 and 2017; our aim is to provide groundwork for future fundamental and applied research spanning parental care, animal dispersal, disease spread, habitat use in relation to color patterns, and intra-specific communication, to name a few. We report sex differences in habitat use and the striking invasion of tree-fall gaps; describe their courtship and aggressive behaviors; document egg development and tadpole transport; and discuss how the knowledge generated by this study could set the grounds for further research on the behavior, ecology, and conservation of this species.
The co-expression networks of differentially expressed RBPs with TFs and LncRNAs related to clinical TNM stages of cancers
Authors: Lian Shuaibin , Li Liansheng , Zhou Yongjie , Liu Zixiao , Wang Lei
Published: September 2019

Background

RNA-binding proteins (RBPs) play important roles in cellular homeostasis by regulating the expression of thousands of transcripts, which have been reported to be involved in human tumorigenesis. Despite previous reports of the dysregulation of RBPs in cancers, the degree of dysregulation of RBPs in cancers and the intrinsic relevance between dysregulated RBPs and clinical TNM information remains unknown. Furthermore, the co-expressed networks of dysregulated RBPs with transcriptional factors and lncRNAs also require further investigation.

Results

Here, we firstly analyzed the deviations of expression levels of 1,542 RBPs from 20 cancer types and found that (1) RBPs are dysregulated in almost all 20 cancer types, especially in BLCA, COAD, READ, STAD, LUAD, LUSC and GBM with proportion of deviation larger than 300% compared with non-RBPs in normal tissues. (2) Up- and down-regulated RBPs also show opposed patterns of differential expression in cancers and normal tissues. In addition, down-regulated RBPs show a greater degree of dysregulated expression than up-regulated RBPs do. Secondly, we analyzed the intrinsic relevance between dysregulated RBPs and clinical TNM information and found that (3) Clinical TNM information for two cancer types—CHOL and KICH—is shown to be closely related to patterns of differentially expressed RBPs (DE RBPs) by co-expression cluster analysis. Thirdly, we identified ten key RBPs (seven down-regulated and three up-regulated) in CHOL and seven key RBPs (five down-regulated and two up-regulated) in KICH by analyzing co-expression correlation networks. Fourthly, we constructed the co-expression networks of key RBPs between 1,570 TFs and 4,147 lncRNAs for CHOL and KICH, respectively.

Conclusions

These results may provide an insight into the understanding of the functions of RBPs in human carcinogenesis. Furthermore, key RBPs and the co-expressed networks offer useful information for potential prognostic biomarkers and therapeutic targets for patients with cancers at the N and M stages in two cancer types CHOL and KICH.
Health Benefit-risk Analysis of Locally Cultivated Mango Fruits and Branded Mango Beverages in Adamawa State, Nigeria

Published: September 2019

In this study, the vitamin, nutrient, antinutrient and heavy metal concentrations in Powdered mango fruit juices (sachet brands) (PMFJ), Liquid mango fruit juices (LMFJ), and Fresh or raw mango fruits juices (FMFJ) were assessed toward establishing a tradeoff between their health benefits and potential health risk on consumption. The analysis show the concentration of vitamin C constituting 50-70% and Vitamin A 30-40% by composition relative to other vitamins. The highest concentration of vitamin A and C were observed in the PMFJ, and the LMFJ samples. Relative to the bioavailability of vitamin E, K, B1, B2, B6 and B12, FMFJ contains the highest concentrations compared to PMFJ and LMFJ. The results further show the highest concentration of 0.79 mg/100 g and 6.85 mg/100 g of oxalate and phytate in the FMFJ. The analysis of the mineral contents show Ca accounting for over 50%, with FMFJ containing the highest concentration (57%). The concentration of Mg, Mn, Fe, and Zinc all falls within the acceptable range to constitute any potential risk on consumption. Based on the EDI values, the dietary exposure to lead (Pb) was observed to be above the oral reference dose (RfD) values set for Pb in edibles. Further appraisal for non-carcinogenic and carcinogenic risk from Pb exposure gives a THQ values of less than one (<1) and a CRI ≤10-4. Overall, the results show children to be more at risk for Pb exposure than the adults. From the results, it could suffice to say that unhealthy agricultural practices and possible anthropogenic activities could be the probable reasons for the low level of vitamin A and C in the FMFJ samples. Furthermore, could probably be the contributing factors leading to the increasing use of additives and fortified functional foods to meets population demands and nutritional requirements as observed in the PMFJ and LMFJ samples respectively.

Aims: To develop a simple, efficient microwave-assisted synthetic method to prepare 1-Benzyl-3-[(4-methylphenyl)imino]-indolin-2-one and its Co(II) complex, characterize and ascertain their biological significance.

Place and Duration of Study: School of Chemistry, Cardiff University, Wales, United Kingdom (November, 2007); Department of Chemistry & Industrial Chemistry, Department of Biological Sciences and Department of Biochemistry, Bowen University, Iwo, Nigeria (September 2015 and June 2018).

Methodology: N-benzylisatin and 4-methylaniline were microwave irradiated in acetic acid to give 1-Benzyl-3-[(4-methylphenyl)imino]-indolin-2-one (C22H18N2O, L; 58 %). L was microwave irradiated with CoCl2.6H2O in ethanol to yield its Co(II) complex. L was characterized using 1H-NMR, 13C-NMR, IR and Electronic spectra analyses, exact mass and melting point. IR and Electronic Spectra analyses with melting point confirmed the Co(II) complex was formed. The in-vitro antimicrobial activities of L were evaluated against three gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis and Haemolytic Staphylococcus aureus), three gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli and Klebsiella sp.) and three fungi (Aspergillus niger, Trichoderma viride and Penicillium citrinum). The IC50 of L and its Co(II) complex were carried out against DPPH, H2O2 and NO radicals, as well as their reducing power abilities.

Results: Antimicrobial studies revealed L was active against Pseudomonas aeruginosa with a high zone of inhibition (thrice that of tetracycline) and Penicillium citrinum. The IC50 of L against DPPH, H2O2 and NO radicals were 0.561 ± 0.02, 0.3 ± 0.01 and 0.53 ± 0.01 μg/ml respectively, while they were 0.200 ± 0.01, 0.9 ± 0.02 and 0.26± 0.03 μg/ml for Co(II) complex. Their reducing power abilities at IC50 were 0.53 μg/ml (for L) and 0.6 ± 0.03 μg/ml (the complex).

Conclusion: L was synthesized within 15 min and its Co(II) complex within 5 min. L showed good free radical scavenging activities and reducing power when compared with ascorbic acid, while its Co(II) complex even performed better.

Surfactants are a surface-active group of molecular compounds with hydrophobic and hydrophilic moieties in one single molecule that distributes themselves between two immiscible fluids, reduce surface/ interfacial tensions and cause the solubility of non-polar compounds in polar solvents. Besides surface and interfacial activities, they display properties such as solubilization, detergency, lubrication, emulsification, stabilization and foaming capacity. Microbiologically derived surfactants are called biosurfactants. They are produced as either metabolic products or as the surface chemistry of an actual cell. The employment of screening techniques such as surface tension measurements, drop collapse test, oil spreading assay, emulsification index (%EI24), cetyltrimethylammonium bromide (CTAB)/methylene blue agar plate test and strain characterization. Others are analytical techniques including liquid chromatography-mass spectroscopy, thin layer chromatography, high-performance liquid chromatography, Fourier transform infrared spectroscopy, nuclear magnetic resonance, fast atom bombardment-mass spectrometry and electrospray ionization-mass spectrometry. These have led to the identification of biosurfactant producing microorganisms, properties and characterization of biosurfactants. Therefore, this review tends to provide the current knowledge of the screening techniques and chromatography/spectroscopic tools employed to study biosurfactants. Results from a detailed study of these tools can unveil new surfactant producing microorganism, decipher chemical diversity and multifunctional properties of biosurfactants critical for applications in diverse industrial sectors.

Occupational hazards arising from physical agents present in wood harvesting equipment may cause irreversible damage to the health of exposed operators. Thus, the objective of this study was to quantify the noise and vibration levels emitted by three types of wood harvesting equipment (Feller-buncher, Harvester and Forwarder) in a forestry company in north-eastern Brazil during a workday. Noise measurements were performed with an equivalent noise level meter (audiodosimeter) at the workstation and compared with the limits set in NR-15. To evaluate the vibration was used a full cup gauge, which has a sensor called triaxial accelerometer (directions X, Y and Z), installed on the operator's seat. As a result, the average noise dose of all activities in the operation studied did not exceed the maximum allowable limit of 85 dB (A) for 8 hours of continuous work. The whole body vibration in all equipment was below the exposure level, however, some equipment obtained indexes slightly higher than the alert level, a fact that shows a higher accuracy in the equipment.
