Authors: Trikoz N. N.
Published: February 2020

The objective of the research is to assess the species diversity of entomoacarocomplex of phytophagans of park cenoses of the Southern Coast of the Crimea, to identify dominant species and to determine the factors controlling their number and distribution. The research methods are the following: biological survey, visual inspection, pheromone traps, the definition of species by morphological characteristics. During the period from 2005 to 2018, the species composition of the entomoacarocomplex of phytophagans of ornamental crops in the parks of the Southern Coast of the Crimea has changed significantly under the influence of abiotic factors, anthropogenic load, development of tourism, business relations, increase in introduction works, change in the assortment of pesticides. Currently, the fauna of arthropods in the parks is represented by 55 species of phytophagans from 7 orders and 23 families, which include aboriginal, introduced and invasive species. Systematically phytophagans are sorted as follows: order Homoptera - 30 species, Hemiptera - 2, Hymenoptera - 1, Lepidoptera - 10, order Diptera - 2, Coleoptera - 7, Acariformes - 3 species. Homoptera order remains the most numerous in the number of species, which accounts for 54.5% of the total number of phytophagans. The dominant species among the local species are euonymus scale, viburnum scale, osier spittlebug, pistache marginal gall aphids, twospotted spider mite. Uncontrolled import of planting material from the European countries has led to the emergence of invasive species with high bio-potential, environmental plasticity, aggressiveness and causing invasions in the parks of the Southern Coast, which leads to the death of plants of local flora and introducents. Currently, 12 invasive species of pests have adapted on the territory of the Crimean parks. The process of invasions continues; it will lead to significant changes in the species composition of phytophagans.

Published: February 2020

The aim of this study was to examine the chemical composition of the major volatile components of bamboo leaf hydrosols and their antimicrobial activities. The chemical components were analyzed using gas chromatography-mass spectrometry and 45 compounds were identified from bamboo leaf hydrosols. The major volatile compounds (%) determined were ionone (16.76%), damasone (10.38%), geranylacetone (7.98%) and β-ionone (6.68%). The antimicrobial activities were evaluated against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Saccharomyces cerevisiae (VINTAGE WHITE and ES488). The inhibition zone and minimum inhibitory concentration test results showed that bamboo leaf hydrosols had the highest antimicrobial activity against gram-positive bacteria. The antimicrobial stability tests showed that the hydrosols also exhibited good stability under heat treatment, change in pH, and exposure to UV irradiation. Results of cell constituent release assay and atomic force microscope observations indicated that bamboo leaf hydrosols destroyed the cell wall and cell membrane permeability causing leakage of intracellular constituents.

Published: February 2020

Iron is an essential mineral for organisms and due to environment iron deficiency and pollution it is very important to understand and monitor the iron homeostasis. Thus, the concentration of iron is very important in hematological and biochemical parameters because iron is component of hemoglobin, erythrocytes, and myoglobin -being part of oxygen-binding proteins. The aim of our experiment was to try a natural protection with fresh, organic plants administration � of iron overload in rabbits. Thereby, we administrated ferrous gluconate (hydro-solution, 15g Fe2+/body weight) as intraperitoneal injection for 43 days to German Lop Eared breed rabbits, and in the same time we tried to protect the animals with a diet consisting in black cumin seeds; clover, chives, leek, parsley, coriander, rucola, radish, fenugreek - leaves; cucumber and carrots. At the end of experiment we analyzed the protein electrophoresis (albumin, a1-globulin, a2-globulin, b1-globulin, b2-globulin and g-globulin), total iron binding capacity, and transferrin concentration. The analytical results demonstrated that plant administration was beneficial for iron homeostasis and the tested blood parameters did not record significant variations between control and experimental group, which proves that diet is very important in health and homeostatic mechanisms in living organisms.
Role of Electrolyte Gels in Signal Transmission Across the Interface Between Skin and Surface Electrodes in Hand Exoprosthesis

Published: February 2020

A key component of a successful external myoprosthesis is not a part of the prosthesis, but an area: the interface between the prosthesis and the amputation stump. This is because in this area takes place a critical exchange of information, in the form of a myoelectrical signal being transferred from the muscles, through the fascia, fat and skin, to the surface EMG sensors, that in turn transfer this information to a part of the prosthesis that is responsible with the analysis, augmentation and use of this signal in order to control the movements of the electromechanical parts of the prosthesis. Any condition that leads to an impaired transmission of information from the skin to the EMG sensors inevitably leads to an underperformance of what may otherwise be a highly developed model of exoprosthesis, thus potentially rendering it no more useful than a basic mechanical model. We aim to review the possible difficulties that may arise in this area, and that may lead to a faulty transfer of signal, with a loss in quantity or quality. For this purpose, we will review the current literature for this subject, including reference books and articles, and complete this information with our personal experience. In doing this, we hope to provide a guide to practitioners, bioengineers and patients alike, in order to be able to anticipate and correct any potential problem as they may arise.

Authors: Kong Song Il , Borcea Anca , Cursaru Diana , Ciuparu Dragos
Published: February 2020

The mechanism and kinetics of gas phase synthesis of ethyl-tert-butyl ether (ETBE) in the reaction between tert-butyl alcohol (TBA) and ethanol (EtOH) were investigated performing the reaction in a continuous flow quartz reactor at different temperatures and atmospheric pressure, using a heteropoliacid catalyst with 30wt% loading, dispersed on MCM-41. The Eley-Rideal reaction mechanism was previously proposed based on experimental observations that showed the rate of ETBE increased when partial pressure of tert-butyl alcohol increased, and the partial pressure of ethanol decreased, without significant effects on product selectivity. The kinetic model based on the Eley-Rideal mechanism was proposed and successfully employed to model accurately the experimental data at three different temperatures. The apparent activation energy and the frequency factor of the etherification reaction were 39.42 kJ/mol and 1.69 x 108 mol/kg . h . bar, respectively.

Published: February 2020

In this paper, the influence of enzymatic pretreatment on the microwave assisted extraction (MAE) of polyphenols from artichoke leaves is described. Prior to enzymatic pretreatment, the influence of different parameters (extraction time, stirring rate, and extraction temperature) on the extraction process was studied. The total phenolic content (TPC) increases with the stirring rate. To avoid degradation of polyphenols, the extraction time and temperature should not be too high. The antioxidant capacity is in concordance with the TPC results. The enzymatic pretreatment, for the best extraction conditions, enhances the concentration of polyphenols compared with the extracts obtained without pretreatment.

Authors: Rehman Rabia , Kanwal Farah , Mitu Liviu
Published: February 2020

In this work, microwave treated Gardenia jasminoides leaves (MTGL) were employed to remove Direct Red-28 (DR) dye from aqueous medium. Most of DR dye contents removed within 30 minutes at pH 2 and 350 ppm dye concentration by 0.02 mg MTGL. Maximum dye adsorbed by MTGL (88.50 mg/g) was approximately triple than non treated simple Gardenia jasminoides leaves (34.13 mg/g). Adsorption modelling of equilibrium data indicated that removal of DR dye by MTGL followed Langmuir, Freundlich and pseudo-second order kinetic models, having exothermic nature. Desorption studies indicated the reusability of MTGL on larger scale. So it is clear that Gardenia jasminoide leaves can be used on larger scale for anionic dye removal after treatment with formalin in efficient manner.

Organophosphates (OP) are frequently used worldwide as pesticides in both agriculture and human households leaving toxic residues in food or living environment. OP act through acetylcholinesterase (AChE) inhibition and acute poisoning carries a higher risk of mortality due to parasympathetic overstimulation. Long-term exposure leads to nervous, hepatic or renal dysfunction. Chlorpyrifos, one of the most commonly used compound appears to cause hyperglycemia, insulin resistance and the risk of developing diabetes after prolonged exposure. The aim of this article was to assess the impact of acute OP poisoning on glycemic status in weanling mice.

Vital abutments presents different degree of dentinal sensitivity (DS) after their preparation. Protective methods of dentinal wound have the purpose to fill up the dentinal tubules. The objective of the study was to assess the efficacy of three different desensitization methods applied to reduce the postoperative sensitivity of prepared vital abutments. The clinical trial included 65 patients with 251 vital abutments, divided into three groups: in the first group of 21 patients (82 vital abutments) the protection method was carried out by a desensitizer agent containing hydroxyethyl methacrylate and glutaraldehyde; in the second group of 22 patients (85 vital abutments), diode laser therapy was used; in the third group of 22 patients (84 vital abutments), associated protection method was applied, by using the same desensitizer agent and laser therapy. During the study, all selected patients used the same toothpaste for at-home desensitization, containing 5% calcium sodium phosphosilicate (CSPS). The evaluation of the painful intensity of DS in vital abutments after desensitization was realized by using a Visual Analogue Scales (VAS) and by evaluating the failure rate. The results of study showed that after desensitisation, the DS of vital abutments has decreased in all three groups, but the highest desensitization rate with the most reduced rate of failures was found in the third group of patients, with associated therapies. The efficiency of the applied desensitization methods have been confirmed.

Published: February 2020

In medical literature, existing studies show the opportunity to use fluorine for one�s health. The presence of this substance in the normal composition of all tissues and organs of the human body as well as deficiencies highlighted under certain circumstances support this aspect. They show both the positive effects of fluorine, such as the role of fluorine in increased calcium storing in the bones and teeth, and the negative effects, for example inhibition of phosphatases, (enzymes used in many metabolic processes). The double effect also appears in the use of fluorine in treatments, because when overcoming a critical threshold for the body it may produce adverse effects, sometimes leading to death. The present article analyzes these effects, the primary purpose being to raise awareness and identify the reactions of fluorine on the body.

Published: February 2020

Chemicals used in the manufacture of synthetic fibers have been associated with undesirable side effects such as itching or skin lesions and it seems that they are involved in the induction of pathological processes such as oxidative stress and inflammation. Lichen planus (LP) can be regarded as an inflammatory disorder, chemical and physical factors playing an important role in the perpetuation of the inflammatory process. Gamma-glutamyl transpeptidase (GGT) plays an important role in the preservation of skin architecture and modulation of skin inflammation. In this study, we found that GGT activity is increased in LP patients with mild inflammation, whilst GGT is inactivated under conditions of severe inflammation. Therefore, GGT is involved in the inflammatory process, but there is no a positive correlation between its activity and the intensity of the inflammatory response. This functional adaptation of the enzyme may be due to down-regulation of its synthesis under free radical overload conditions. Understanding the molecular mechanisms involved in the modulation of intracellular redox homeostasis is an important step in the pharmacological management of patients with LP.

Authors: Bloch Katarzyna
Published: February 2020

In this paper the results of the structural and magnetic properties for bulk amorphous alloys Fe65Co10Y5B20 and Fe63Co10Y7B20 were presented. For the structural investigation was performed by X-ray diffractometry and Mossbauer spectroscopy. It was found that investigated samples were amorphous in the as-cast state. The magnetisation was measured within magnetic fields ranging from 0 to 2T using a vibrating sample magnetometer (VSM). On the basis of the hysteresis loops, the saturation magnetization value and the coercive field were determined.The investigation of the �magnetisation in the area close to ferromagnetic saturation� showed that the magnetisation process in strong magnetic fields is connected with point defects and Holstein-Primakoff paraprocess. Analysis of the high-field magnetization curves has facilitated the calculation of the spin wave stiffness parameter.

The present study quantified the effect of difenoconazole (DFC) on bacteria and mold communities grown in laboratory conditions, in treated soil microcosms difenoconazole, using the following concentrations: control, half dose (0.037 mg DFC / g soil, HD), normal dose (0.075 mg DFC / g soil, ND) and double dose (0.150 mg DFC / g soil, DD). The microbiological analysis included mesophilic bacteria involved in the nitrogen cycle: aerobic and anaerobic nitrogen-fixing, ammonifying, nitrifying and denitrifying bacteria. The mesophilic bacteria were incubated at 37�C and identified qualitatively on solid growth medium (Nutrient agar), whereas soil fungi were identified both quantitatively and qualitatively on solid growth medium (Potato-Glucose-Agar). In high doses, the DFC decreased the microbial communities involved in nitrogen cycle, namely aerobic and anaerobic bacteria and denitrifying bacteria. Noticeable was the response of two genera, namely Mucor sp. and Actinomucor sp., that showed resistance to the toxic effect of DFC, underlying their potential further practical use in the decontamination of polluted soils.

Malnutrition has been known to provide poor survival outcomes in systemic sclerosis (SSc). We recruited a series of 40 consecutive SSc patients, 22 (55%) with limited cutaneous involvement and 18 (45%) with the diffuse form of disease. The study group was evaluated using the modified Rodnan skin score (mRSS), anthropometric measurements, the EPIC-Norfolk Food Frequency Questionnaire, the Malnutrition Universal Screening Tool (MUST) as well as circulating albumin and vitamin D. MUST scores were correlated with mRSS and serum albumin (R=0.40, p=0.010, and R=-0.46, p=0.003, respectively). Serum vitamin D values were inversely related to mRSS (R=-0.35, p=0.026). We recorded a greater number of daily gastrointestinal symptoms associated with diets rich in sodium, fat, sugars and snacks, carotene, and �-tocopherol equivalents (vitamin E) in our study population. Scleroderma patients might benefit from nutritional counseling in order to follow a diet tailored to their specific needs.

Published: February 2020

The paper aims to present the investigation of H2 adsorption capacity in metal doped nanostructured materials, by using two methods. Carbonic materials are considered to be one of the most promising materials to be used for hydrogen adsorption and storage. They have different applications and one of the most important is considered to be fuel cells technology. By using metals for doping these materials, the adsorption capacity increases, thus approaching the target of 6.5% weight ratio of H2 adsorbed in a substrate. Within these investigations multi-wall nanotubes and poly-aniline have been used as substrates. The poly-aniline has been prepared and doped in laboratory while the nanotubes used in experiments have been purchased from the market and afterwards doped in laboratory. The doping procedure consists of a physical-chemical method which involves salts of the metal for doping and the use of ultrasounds in order to activate the substrate for doping. The adsorption capacity of the carbonic materials has been determined by using spill over phenomena in a PCT Pro-User apparatus, provided by SETARAM and also by cyclic voltametry, by using VoltaLab-40 apparatus. In order to investigate the adsorption capacity of the nanostructured carbonic materials, the experiments have been carried out at different pressures. Both substrates have been characterized in order to determine their porosity, BET surface and structure. The collected data have been processed by using the PCT Pro-User apparatus�s software. The results have been compared with the available data from literature and a good consistency was found.

There is an increased interest and more studies highlight the fact that bone strength depends not only on bone tissue quantity, but also on its quality, which is characterized by the geometry and shape of bones, trabecular bone microarchitecture, mineral content, organic matrix and bone turnover. Fibrillar type I collagen is the major organic component of bone matrix, providing form and a stable template for mineralization. The biomedical importance of collagen as a biomaterial for medical and cosmetic purposes and the improvement of the molecular, cellular biology and analytical technologies, led to increasing interest in establishing the structure of this protein and in setting of the relationships between sequence, structure, and function. Bone collagen crosslinking chemistry and its molecular packing structure are considered to be distinct features. This unique post-translational modifications provide to the fibrillar collagen matrices properties such as tensile strength and viscoelasticity. Understanding the complex structure of bone type I collagen as well as the dynamic nature of bone tissues will help to manage new therapeutic approaches to bone diseases.

Published: February 2020

Removal of some pollutants (Basra, Azeri, and Rebco crude oils, diesel, gasoline, and 1/1 (w/w) diesel-gasoline mixture) from water by sorption using Romanian Merino wool as a natural sorbent was studied in this paper. Batch experiments were conducted at different levels of initial sorbent mass (1 and 3 g), oily water pH (5 and 10), and operating temperature (30 and 45 �C). The effects of these factors on wool sorption capacity were evaluated. The sorption capacity of more viscous fuels (crude oils), i.e., 4.13-21.87 g/g, increased with an increase in oily water pH and a decrease in initial sorbent mass and temperature. For less viscous pollutants (diesel, gasoline, and their mixture), the sorption capacity (3.32-9.19 g/g) increased with a decrease in sorbent mass, the effects of pH and temperature being negligible. Experimental results were processed according to a 2 3 factorial plan and regression equations between the process factors and sorption capacity were obtained. SEM analysis revealed that the removal process was governed by both adsorption and absorption mechanisms.
Does Gravity Fall Down? Evidence for Gravitational-wave Deflection along the Line of Sight to GW170817

We present a novel test of general relativity (GR): measuring the geometric component of the time delay due to gravitational lensing. GR predicts that photons and gravitational waves follow the same geodesic paths and thus experience the same geometric time delay. We show that for typical systems, the time delays are tens of seconds, and thus can dominate over astrophysical delays in the timing of photon emission. For the case of GW170817, we use a multi-plane lensing code to evaluate the time delay due to four massive halos along the line of sight. From literature mass and distance measurements of these halos, we establish at high confidence (significantly greater than

) that the gravitational waves of GW170817 underwent gravitational deflection to arrive within 1.7 s of the photons.
X-ray microcomputed tomography applied to the taxonomic study of rare material: redescriptions of seven of Schirch’s Brazilian species of land planarians (Geoplanidae, Platyhelminthes)
Authors: Silva Marcos Santos , Carbayo Fernando
Published: February 2020

In 2016, the type-material of ten of the 15 Brazilian land planarians (Platyhelminthes, Tricladida, Geoplanidae) described by Schirch (1929) was discovered deposited in the Museu Nacional do Rio de Janeiro (MNRJ). Schirch only described the external morphology of these species, all originally placed in the genusGeoplana. By the 1930s and 1950sGeoplana itatiayana,G. plana, andG. rezendeiunderwent taxonomic revision based on the study of non-type specimens. The remaining 12 species also underwent a taxonomic revision but only based on the literature. Current names of these species areGeoplana goettei,Pseudogeoplana arpi,Ps. blaseri,Ps. bonita,Ps. bresslaui,Ps. cardosi,Ps. doederleini,Ps. lumbricoides,Ps. obscura,Ps. riedeli,Ps. theresopolitana, andPs. wetzeli. The speciesGeoplana maximilianisensu Schirch (1929) was renamed asPs. schirchiOgren & Kawakatsu, 1990.

The present study reports a taxonomic revision of seven of Schirch’s species using type material, namelyObama itatiayana,Pasipha plana,Pseudogeoplana arpi,Ps. bresslaui,Ps. doederleini,Ps. schirchiandPs. wetzeli. Additional specimens of some of these species were also examined. Morphological data from histological preparations and from virtual sections were obtained through a non-destructive technique of X-ray computed microtomography (µCT). This approach resulted in the preservation of the entire body of at least one type-specimen of each species, and the holotype ofPs. bresslaui. Conspecificity ofO. itatiayanaandP. planawas confirmed, as previously reported in the literature. It is also proposed thatPs. bresslauibelongs to the genusParaba, while the other species should remain inPseudogeoplana, since type-specimens are either immature, poorly preserved or simply lost.
Communication for health in Africa: experiences and challenges
Authors: Balima Serge-Théophile
Published: February 2020

This paper analyzes communication for health in Africa through some fields experiences. These education compaigns show that the communication approaches are little participative. They don’t take into account the socio–cultural reality of local communities and then face various methodological problems. Yet, if well conducted, health oriented communication can help to reduce the impact of recurrent health problems in Africa.

El presente artículo analiza la comunicación para la salud en África a través de algunas experiencias llevadas a cabo sobre el terreno. De estas campañas de educación se deduce que los enfoques de la comunicación son poco participativos. No integran la vivencia sociocultural de las poblaciones locales y se topan con una serie de dificultades de orden metodológico. Sin embargo la comunicación para la salud, bien enfocada, puede lograr reducir el impacto de los problemas de salud recurrentes en el continente.
The protagonism of the mass media in student’s education
Authors: Martínez-Fresneda-Osorio Humberto
Published: February 2020

The emergence of the media as a complementary school parallel to schools, invites the educational community to rethink about the most effective way to integrate media into the school curriculum in order to encourage and help students in their education. Through this relationship among mass media reality and students themselves, schools arises as the key where offering a correct media interpretation.

La aparición de los medios de comunicación como «escuela» complementaria de formación, paralela a los centros escolares, invita a la comunidad educativa a replantearse la manera más efectiva de integrarlos en el currículum escolar con el fin de ayudar al alumno en su proceso de formación. De esta relación de los medios de comunicación con la realidad y los propios alumnos se desprende la necesidad de ofrecer, desde la escuela, claves para su correcta interpretación.

Nowadays media images rule our lives. However, in early ages it is considered necessary the help of a guide to discriminate information. We want to make people reflect about the need to promote specific training on the media since childhood.

La realidad de hoy presenta una imagen en la que los medios de información y comunicación dominan nuestras vidas. Este avance permite desarrollar nuevas formas de transmitir nuestros pensamientos e ideas. Sin embargo, en edades tempranas se considera necesaria la intervención de un guía que ayude a discriminar la información. En consecuencia, se debe reflexionar sobre esta necesidad de potenciar una formación específica en medios de comunicación desde la más tierna infancia.

Although weight training can enhance muscular strength, power, and body composition, outdated beliefs about muscular adaptations have limited its use in dancers. The purpose of this study was to investigate the effect of an 8-week progressive overload resistance-training (RT) program on muscular strength, power and body composition in collegiate female dancers. Sixteen subjects were randomised into a dance-only control group (CON) or an RT + dance training group (EXP). EXP met 3×/week for RT. Body fat (%BF), lean body mass (LBM), girth measurements, vertical jump (VJ), muscular strength (1-repetition max (RM) squat (SQT) and 1-RM bench press (BP)), maximal oxygen consumption (V̇O2max, and ventilatory threshold (VT)) were assessed pre- and post-study. Baseline performance characteristics across all subjects were: %BF=28.2±5.7%, VJ=33.4±5.4 cm, SQT=57.5±12.1 kg, BP=30.1±7.6 kg, (V̇O2max)=40.6±3.4 ml/kg/min, and VT=71.2±3.4%VO2max. Strength improvements were significantly greater for EXP than CON (P<0.05). No significant differences were found between groups for %BF, LBM, girth measurements, VJheight, (V̇O2max), or VT (P>0.05). However, a trend was observed for VJpowerfavouring EXP (P=0.07). EXP significantly improved strength, while no significant changes were observed in body composition. However, EXP improved their power-to-weight ratio, which may be a positive performance adaptation. RT for dancers can improve strength and power, allowing enhanced muscular loading and fatigue-resistance, which may optimise performance and decrease injury risk.
Unveiling Cybercrime in a Developing Country
Authors: Boateng Richard , Barnor Jonathan Nii Barnor
Published: February 2020

This article unveils the pervasiveness of cybercriminal activities in Ghana from the point of view of key stakeholders in the fight against the crime. From a critical realist's perspective, the authors employed a qualitative approach to understand cybercrime from the point of view of different key players—four cybercriminals, eight lawyers, eight bankers, six café operators and personnel from the cybercrime unit of the Ghana Police—for the study. Findings from the article pointed out that cybercrime has gained ground among Ghanaian youth between the ages of 12 and 35, mostly males with female decoys. The findings of the article also suggested lack of confidence in the Ghana Police service to crackdown on cybercriminal activities in Ghana. The research finally suggested that there seem to be the nonexistence of cybercrime policies and laws for lawyers to arraign or defend suspected criminals in Ghanaian courts of law.
