Authors: Abdul Wahab Ibtisam , Mohsin Hannis Fadzillah
Published: June 2019

This research is about the natural product of coriander, or the Coriandrum species. The bioactive molecules and the health effects of this plant are constantly discussed. This paper is parallel with those publications, investigating the composition of the herb. The results of current study indicates that the Coriandrum seed is a source of fatty acids. From the publications, petroselinic acid or (6Z)-octadecenoic acid, is the major fatty acid in the coriander extracts. Previous articles reported on coriander’s chemical constituents, biological activities of the coriander’s seeds and leaves, as well as the coriander products in the retail. Indeed, coriander has a lot of uses either as a traditional medicine or spices. Different forms of coriander samples were subjected to a simple maceration by using chloroform. From the chromatographic purification of the seed crude extract, its component could include anisaldehyde, as one of the aromatic aldehyde. It is concluded that the lipid-containing fraction of the coriander seed could also consist of dipetroselin, a diglyceride.

Published: June 2019

Composite panels were manufactured from kenaf particles and treated with two different alkali treatments using 2% NaOH and 2% KOH with resin contents of 8% and 10% of phenol formaldehyde (PF) at medium density of 650kg/m3. The objectives of this study were to determine the mechanical properties in terms of its modulus of rupture (MOR), modulus of elasticity (MOE) and internal bond (IB), and physical properties namely thickness swelling (TS) and water absorption (WA) of treated kenaf board. The mechanical and physical tests were performed according to the Malaysian Standard (MS1787:2004). The minimum requirements value for MOE, MOR and IB were 2000 MPa, 14 MPa and 0.45 MPa respectively for furniture grade particleboards for use in humid conditions (PF2). According to Malaysian specifications for physical properties, the maximum requirement for thickness swell is 15%. Results indicated that both treated boards with NaOH and KOH showed an increase in strength properties compared to untreated particleboard. Particleboard treated with KOH exhibited the highest MOR and MOE values, while board with NaOH treatment gave the highest IB value. The boards with treated particles gave better performance in terms of physical properties. There were no significant differences in mechanical properties (MOR, MOE and IB) and physical properties for the different alkali treatment. The values of bending strength and IB strength increased with an increase in resin content, while TS and WA increased with a decrease in resin content. In conclusion, NaOH and KOH treated kenaf particles improved board performance and could be considered as an alternative material for particleboard production.
¿De qué hablamos cuando hablamos de medicalización? Sobre adjetivaciones, reduccionismos y falacias del concepto en ciencias sociales
Authors: Bianchi Eugenia
Published: June 2019

En ciencias sociales, el concepto de medicalización está presente como asunto de agenda cultural, social, económica y polí­tico-legislativa, y es convocante en espacios académicos, investigativos y clí­nico-profesionales. Simultáneamente, en estos espacios se evidencian inexactitudes ligadas al concepto y su circulación, que suponen limitaciones y fragilidad argumentativa. Sintetizo las inexactitudes en tres lí­neas: adjetivación, reducción e impropiedad, cuyos lí­mites entre sí­ son más analí­ticos que empí­ricos. El objetivo de este escrito es presentar algunas implicancias o corolarios teórico-metodológicos que se derivan de estas inexactitudes, empleando métodos analí­tico-interpretativos sobre bibliografí­a especí­fica, nacional e internacional, y con el ejemplo empí­rico del TDAH.
Análisis de la inclusión de la Comunidad Andina en el proyecto “Cinturón y Ruta” para el desarrollo de la infraestructura ferroviaria
Authors: Cerbone Pascuale
Published: June 2019

El presente artículo proyecta la inclusión de los países miembros de la Comunidad Andina en una eventual extensión del plan chino “Cinturón y Ruta” en la región suramericana; esto con el fin de responder a la exigencia de mejora de la infraestructura para el transporte ferroviario entre los países miembros de la Comunidad Andina, con el fin de identificar los posibles efectos que esto puede conllevar para el comercio internacional, la integración y la visión geopolítica de los países que conforman la organización. La metodología propuesta en este artículo, en cuanto a la evaluación de la factibilidad de la propuesta, se basa en una amplia revisión bibliográfica con miras a la identificación de elementos que posteriormente se relacionarán al interno de una matriz FODA de tipo ponderada. Dichos elementos atienen a las relaciones internas entre los países de la organización subregional, y de los mismos con el socio chino. Las conclusiones muestran que tanto para el comercio internacional como para la integración regional el proyecto no aportaría con particulares ventajas para los miembros de la Comunidad Andina; sin embargo, podría modificar la proyección geopolítica que ellos mantienen tanto a nivel regional como global
Datos personales: seguridad nacional y concertación internacional. La disyuntiva latinoamericana
Authors: Halperin Marcelo
Published: June 2019

Conmovieron a la prensa internacional las restricciones adoptadas por el gobierno estadounidense, primero para impedir compras gubernamentales (Ley de Autorización de Defensa Nacional 2019) y, más recientemente, para evitar la actualización de sistemas operativos de equipos de telecomunicaciones suministrados por empresas chinas (Orden Ejecutiva del Presidente, del 16 de mayo de 2019). Pero rápidamente se advirtió que las últimas medidas podían resultar no sólo ineficaces sino, peor aún, producirían efectos adversos. La amenaza que representa el desarrollo de redes y sistemas de alta velocidad para la manipulación de datos y, por extensión, para la seguridad nacional de Estados Unidos (EUA), ya no podría neutralizarse con medidas comerciales ni mediante las reglas de propiedad intelectual. En este sentido, la modalidad de código abierto en las patentes de sistemas operativos para dispositivos electrónicos, pone en evidencia que los estatutos de propiedad intelectual están flexibilizándose y adaptándose a muy aceleradas sustituciones tecnológicas, las cuales, en el sector de las tecnologías de la información y las comunicaciones (TIC) apuntan a la captura y manipulación de datos personales con una voracidad inédita.

En este contexto y con motivo del flujo electrónico de datos personales desde la Unión Europea (UE) hacia EUA y ante la dificultad para armonizar sus normas, en los últimos años se habilitó un “Escudo de Privacidad” con el objeto de garantizar los derechos de los usuarios y compatibilizar la actividad de empresas tecnológicas con los principios de interés público en ambos lados del Atlántico. Este régimen podría ser un valioso antecedente en el diseño de un acuerdo internacional de carácter multilateral destinado a reglar la conectividad global.

Published: June 2019

Traditional markets in Vietnam are considered as important places for trading medicinal plants and also play a social role of exchanging traditional use of herbal medicine among different cultural and social groups at the local level. This study aims to identify and document medicinal plants used in 32 traditional markets of Son La province. Data were obtained through interviews and field observation method. A total of 167 informants include 13 herbalists, 49 herbal sellers, and 105 local people were interviewed. The study collected a total of 99 plant species belonging to 88 genera and 57 families. Identified plant species are used by local people for the treatment of 61 different diseases. Leaves, stems and roots are most commonly used either fresh, dried or by decocting the dried parts in water. In the study, the Relative Frequency of Citation (RFC) ranged from 0.02 to 0.44; the Use Value (UV) ranged from 0 to 0.84; the Informant Consensus Factor (ICF) ranged from 0.84 to 1; the Fidelity Level (FL) ranged from 44.44% to 100%. Villagers view and our observations confirmed that knowledge about the number of medicinal plants available in the study area and used by interviewees positively correlated with the threats on medicinal plants in the wild habitats. Illegal and unsustainable exploitation by the local people is a major cause of their depletion from nature.

Published: June 2019

Susceptibility to addiction has a complex genetic basis that includes genes associated with the action and metabolism of drugs of abuse. One important gene in that respect is OPRM1, which codes for the μ-opioid receptor and has an important role in mediating the rewarding effects of addiction substances. The aim of our study was to assess the prevalence of the OPRM1 A118G polymorphism (rs1799971) in Turkish population and to investigate its association with opioid and other substance addiction. In addition, we examined the association of rs1799971 in addicted patients who were also diagnosed with psychiatric disorders. The study included 103 patients addicted to opioids, cocaine, ecstasy, alcohol, lysergic acid diethylamide (LSD), cannabis, and sedative/hypnotic substances and 83 healthy volunteers with similar demographic features as controls. rs1799971 polymorphisms were identified with the polymerase chain reaction restriction fragment length polymorphism method (PCR-RFLP). The genotype frequencies were significantly higher in the addicted patients than controls (32.0 % vs 16.9 %, respectively; p=0.027). The prevalence of the G allele was 16.1 % in the addicted group and 8.4 % in the control group (p=0.031). Our study confirmed the association between the rs1799971(G) allele frequency and opioid and other substance addiction, but not with psychiatric disorders.

Published: June 2019

The use of electronic cigarettes or vaping has been gaining momentum among Macedonian smokers but has also raised great many concerns about the toxicity of liquid refills and its aerosols, especially as the nicotine levels in refill liquids (e-liquids) are not required to be declared accurately or at all by current regulations. The aim of this study was therefore to determine nicotine levels in fifteen samples of e-liquids purchased in specialised shops in Macedonia using gas chromatography. Nicotine concentrations deviated from manufacturer’s declarations in nine of the twelve samples: in five they were higher and in four lower than declared, ranging from −16.7 % to +30.0 %. These significant discrepancies between the actual and declared nicotine concentrations in the analysed e-liquids call for closer attention of the healthcare and the regulating authorities.
Management recommendations for body stuffers at emergency units
Authors: Hassanian-Moghaddam Hossein , Amraei Fatemeh , Zamani Nasim
Published: June 2019

Managing body packers and stuffers is a challenge to emergency physicians, stuffers in particular, as there is no systematic approach to their treatment. The aim of this study was therefore to review all available literature on body stuffing and propose a guide to manage these patients. We searched Medline/PubMed, Google Scholar, and Scopus for published work on body stuffers using key words “body stuffer”, “body stuffing”, “poisoning”, “toxicity”, and “treatment” without a time limit and retrieved 290 articles, of which 61 remained after exclusion of those on “body packers” and repetitive documents. This review article evaluates and summarises the information gathered from them. The main step in body stuffer management is observation to make sure that they have passed all the swallowed packages of drugs of abuse. In some cases, imaging can be quite useful. Diagnostic pitfalls may be avoided with abdominopelvic CT without contrast, which is probably the best diagnostic method to determine the presence and the number of packages in these patients. Treatment should be specific for each group of drugs, whether it is opioids, cocaine, or amphetamine. Surgical interventions are indicated for obstruction of the intestines or package rupture. Legal precautions should be taken because of the legal complexity of body stuffing cases.

Individuals chronically exposed to low-level ionising radiation (IR) run the risk of harmful and long-term adverse health effects, including gene mutations and cancer development. The search for reliable biomarkers of IR exposure in human population is still of great interest, as they may have a great implementation potential for the surveillance of occupationally exposed individuals. In this context, and considering previous literature, this study aimed to identify mutations in the human interferon alpha-2b (hIFNα-2b) as a potential biomarker of occupational chronic low-dose IR exposure linking low-IR exposure to the effects on haematopoiesis and reduced immunity. The analysis was performed in the genomic DNA of 51 uranium miners and 38 controls from Kazakhstan, and in 21 medical radiology workers and 21 controls from Italy. hIFNα-2b gene mutations were analysed with the real-time polymerase chain reaction (PCR) or Sanger sequencing. However, none of the investigated workers had the hIFNα-2b mutation. This finding highlights the need for further research to identify biomarkers for early detection of health effects associated with chronic low-dose IR exposure.

Published: June 2019

Exhaled breath temperature (EBT) is a biomarker of inflammation and vascularity of the airways already shown to predict incident COPD. This cross-sectional study was aimed to assess the potential of EBT in identifying “healthy” smokers susceptible to cigarette smoke toxicity of the airways and to the risk of developing COPD by analysing the dynamics of EBT after smoking a cigarette and its associations with their demographics (age, smoking burden) and lung function. The study included 55 current smokers of both sexes, 29–62 years of age, with median smoking exposure of 15 (10–71.8) pack-years. EBT was measured at baseline and 5, 15, 30, 45, and 60 min after smoking a single cigarette. Lung function was measured with spirometry followed by a bronchodilator test. To compare changes in EBT between repeated measurements we used the analysis of variance and the area under the curve (EBTAUC) as a dependent variable. Multivariate regression analysis was used to look for associations with patient characteristics and lung function in particular. The average (±SD) baseline EBT was 33.42±1.50 °C. The highest significant increase to 33.84 (1.25) °C was recorded 5 min after the cigarette was smoked (p=0.003), and it took one hour for it to return to the baseline. EBTAUC showed significant repeatability (ICC=0.85, p<0.001) and was significantly associated with age, body mass index, number of cigarettes smoked a day, baseline EBT, and baseline FEF75 (R2=0.39, p<0.001 for the model). Our results suggest that EBT after smoking a single cigarette could be used as early risk predictor of changes associated with chronic cigarette smoke exposure.

Published: June 2019

The aim of this study was to identify and quantify faecal indicator bacteria in blackwater collected from a source separation unit and determine the amount of E. coli isolates resistant to antimicrobials and their potential to produce extended spectrum β-lactamases (ESβLs) and metallo-β-lactamases (MβLs), which hydrolyse the most important antibiotics used in clinical practice. Most of the isolates were resistant to amoxicillin with clavulanic acid (36.4 %), followed by ticarcillin with clavulanic acid (22.7 %) and tetracycline (18.2 %). ESβL-producing genes bla
CTX-M and bla
TEM were found in three (13.6 %) and four (18.2 %) E. coli strains, respectively, while MβL genes were found in two (9.1 %). By separating at source, this pilot study clearly shows that gastrointestinal bacteria of healthy people can be an important source of antibiotic resistance released into the environment through wastewaters. One way to prevent that is to treat wastewater with a combination of TiO2, UV light, or ozone, as successful methods to remove resistant bacteria and prevent their spread in the environment.
Fuzzy Logic Method for Predicting the Effect of Main Fabric Parameters Influencing Drape Phenomenon
Authors: Hamdi Thouraya , Ghith Adel , Fayala Faten
Published: June 2019

The main aspect of this research was to predict the drape parameters and describe clearly the drape phenomenon using fuzzy logic method. Forecasting features allow manufacturers to save time and improve their productivity. The bending rigidity, (in warp, weft, and skew direction), shear rigidity, and weight of fabric samples were used as the key input variables for the model, whereas drape coefficient, drape distance ratio, folds depth index, and node number were used as output/response variables. The results show that changing the values of fabric parameters significantly affected the fabric drape and a representative correlation values were found between the experimental values and those calculated by the fuzzy system.

Published: June 2019

The present communication reports enhanced myo-inositol biosynthesis under natural conditions in Ulva lactuca Linn. based on the study conducted on its two prime enzymes [L-myo-inositol-1-phosphate synthase (MIPS) and myo-inositol-1-phosphate phosphatase (MIPP)] involved in myo-inositol biosynthesis. The two key enzymes obtained from chloroplastidial sources were partially purified to about 49- and 58-fold, respectively, over the homogenate following low speed centrifugation, high speed centrifugation, 0–80% ammonium sulphate precipitation and successive chromatography using ion exchange, gel filtration and molecular sieve packed columns. MIPS preparations specifically utilized D-glucose-6-phosphate and NAD as its exclusive substrate and coenzyme, while MIPP preparations used D/L-myo-inositol -1- phosphate as its principal substrate. Using non-linear regression kinetics method, the Km values of MIPS for G-6-P and NAD were calculated to be 2.6340 mM and 0.1271 mM, while the Km value of MIPP for D-MIP was recorded to be 0.02128 mM. Both enzymes were remarkably active within a temperature range of 20–40°C, and the optimum pH for both enzymes were found to be 7.5. Different cations and organic modifiers exhibited variable effects on the activity of both enzymes. The content of free myo-inositol was found to increase proportionately with the increase of surface salinity of the Chilika Lagoon, Odisha, India.

Authors: Sokół Rajmund , Gałęcki Remigiusz , Michalczyk Maria
Published: June 2019

The development of female Varroa destructor mites in the bee colonies was examined in the apiculture season through a developed research system in which bee colonies were experimentally infested with fifty V. destructor females. Differences in infestation rates were observed between the control group (C) and the infested group (E). The average number of female mites per colony was determined at 513 in group E and 261.6 in group C. Natural daily mortality reached 0.16 mites in group E and 0.09 mites in group C. In group E, the number of V. destructors increased 7.96 to 13.32-fold, subject to colony. The size of V. destructor populations increased at a higher rate in group E than in group C (F= 12.39, P= 0.047). At the end of the experiment, the percentage of infested honey bee workers was determined at 0.97% in group E and 0.46% in group C. The results of this study confirmed that V. destructor mites continue to proliferate rapidly in honey bee colonies, and that the population growth rate in bee colonies and apiaries has to be closely monitored due to growing levels of resistance to acaricides.
Hydrological and erosional response of a small catchment in Sicily
Authors: Licciardello Feliciana , Barbagallo Salvatore , Gallart Francesc
Published: June 2019

Increasing our understanding of the main processes acting in small Mediterranean catchments is essential to planning effective soil and water conservation practices in semi-arid areas. A monitoring program of a Sicilian catchment started in 1996 and ended in 2006. The factors driving the hydrological response for 170 events with runoff generation and 46 with sediment production were specified. The catchment response varied greatly over the year. Rainfall intensity was a poor driver of runoff generation, whereas both the simulations made with the Thornthwaite-Mather water balance model and hydrograph recession analyses, pointed to the chief importance of wet antecedent conditions and soil saturation processes in runoff generation. The influence of rainfall spatial variability was also examined. SSC-Q relationships, classified by following their shapes for all sediment production events, suggested that the principal role of small poorly vegetated hillslope patches was as sediment sources and confirmed the complexity of the hydrological response in this small Mediterranean catchment.
Finding behavioral parameterization for a 1-D water balance model by multi-criteria evaluation
Authors: Casper Markus C. , Mohajerani Hadis , Hassler Sibylle , Herdel Tobias , Blume Theresa
Published: June 2019

Evapotranspiration is often estimated by numerical simulation. However, to produce accurate simulations, these models usually require on-site measurements for parameterization or calibration. We have to make sure that the model realistically reproduces both, the temporal patterns of soil moisture and evapotranspiration. In this study, we combine three sources of information: (i) measurements of sap velocities; (ii) soil moisture; and (iii) expert knowledge on local runoff generation and water balance to define constraints for a “behavioral” forest stand water balance model. Aiming for a behavioral model, we adjusted soil moisture at saturation, bulk resistance parameters and the parameters of the water retention curve (WRC). We found that the shape of the WRC influences substantially the behavior of the simulation model. Here, only one model realization could be referred to as “behavioral”. All other realizations failed for a least one of our evaluation criteria: Not only transpiration and soil moisture are simulated consistently with our observations, but also total water balance and runoff generation processes. The introduction of a multi-criteria evaluation scheme for the detection of unrealistic outputs made it possible to identify a well performing parameter set. Our findings indicate that measurement of different fluxes and state variables instead of just one and expert knowledge concerning runoff generation facilitate the parameterization of a hydrological model.
The influence of observed and modelled net longwave radiation on the rate of estimated potential evapotranspiration
Authors: Kofroňová Jitka , Tesař Miroslav , Šípek Václav
Published: June 2019

Longwave radiation, as part of the radiation balance, is one of the factors needed to estimate potential evapotranspiration (PET). Since the longwave radiation balance is rarely measured, many computational methods have been designed. In this study, we report on the difference between the observed longwave radiation balance and modelling results obtained using the two main procedures outlined in FAO24 (relying on the measured sunshine duration) and FAO56 (based on the measured solar radiation) manuals. The performance of these equations was evaluated in the April–October period over eight years at the Liz experimental catchment and grass surface in the Bohemian Forest (Czech Republic). The coefficients of both methods, which describe the influence of cloudiness factor and atmospheric emissivity of the air, were calibrated. The Penman-Monteith method was used to calculate the PET. The use of default coefficient values gave errors of 40–100 mm (FAO56) and 0–20 mm (FAO24) for the seasonal PET estimates (the PET was usually overestimated). Parameter calibration decreased the FAO56 error to less than 20 mm per season (FAO24 remained unaffected by the calibration). The FAO56 approach with calibrated coefficients proved to be more suitable for estimation of the longwave radiation balance.

The aim of this study was to evaluate the quality of the ECG signal, obtained from a telemetric body-sensor device during a maximum stress test on an ergometer. Twenty-three subjects, 13 males, were included in the study (20.56±1.19 years). Two different sensor positions were verified on each subject by the concurrent use of two ECG sensors. Each subject participated in four exercise stress tests: two on a treadmill and two on a cycle ergometer. In the first test, both sensors were attached to self-adhesive skin electrodes on the body, while in the second test the sensors were additionally fixed with self-adhesive tapes. The measurements were compared on both ergometers, in terms of the ECG sensors’ positions and the methods used for the sensors’ fixation. The results showed a significant difference in the running speed that provides an assessable ECG signal between the non-fixed and the fixed sensors at position left inferior (p = 0.000), as well as between the positions left inferior and left superior in the first (p = 0.019), and in the second test (p = 0.000) on the treadmill. On the cycle ergometer the differences were significant between the positions left inferior and left superior in the first (p = 0.000), and the second test (p = 0.003), and between the tests with fixed and non-fixed sensors in the position left superior (p = 0.011). The study confirms that ECG sensors could be used for maximal exercise stress tests in laboratories, especially on a cycle ergometer, and that they present a great potential for future use of ECG sensors during physical activity.

The paper presents the developed complex Digital Signal Processing algorithm for the reduction of white and 1/f noise and processing of the measurement signals of the Settling Time Measurement of the Digital-to-Analog Converters. The results show that the proposed DSP algorithm ensures 100-fold suppression of the white noise and 1/f noise. It was shown that it is possible to measure settling times of highspeed DACs (up to 16-17 Bits) with readout levels of ± 0.5 LSB while measurement errors do no exceed ± 1.4 ns.

Electroencephalography (EEG) signals are frequently contaminated by ocular, muscle, and cardiac artefacts whose removal normally requires manual inspection or the use of reference channels (EOG, EMG, ECG). We present a novel, fully automatic method for the detection and removal of ECG artefacts that works without a reference ECG channel. Independent Component Analysis (ICA) is applied to the measured data and the independent components are examined for the presence of QRS waveforms using an adaptive threshold-based QRS detection algorithm. Detected peaks are subsequently classified by a rule-based classifier as ECG or non-ECG components. Components manifesting ECG activity are marked for removal, and then the artefact-free signal is reconstructed by removing these components before performing the inverse ICA. The performance of the proposed method is evaluated on a number of EEG datasets and compared to results reported in the literature. The average sensitivity of our ECG artefact removal method is above 99 %, which is better than known literature results.

The article presents a theoretical analysis of electromagnetic compatibility (EMC) and experimental measurement of effects of radiation and acoustic emission of high-voltage transformers for electronic equipment and working personnel in a control room. Electromagnetic compatibility and safety of equipment are not considered as two distinct areas of study in electric and electronic safety. Economic criteria cannot compromise safety but at the same time immunity levels must be relevant in order to establish a “Functional Safety”. Introducing Special Immunity Levels in the level of equipment testing allows us to combine the two areas of EMC and safety. The measurement was carried out in high-current of very high-voltage distribution station. A real-life analysis of effects of electric and electromagnetic field was carried out. FFT was used for mathematical processing of data which were later presented in a graphical form of a spectrally analyzed area. In the last part of the paper we discuss the suitability of acoustic camera to perform contactless monitoring of the health and operation conditions of the power transformer by analyzing acoustic field generated by the transformer core and windings in near control room.
To the memory of Pápai Páriz Ferenc. The „Pax Corporis”, a home medical book for people

We present the life, career and memory of Pápai Páriz Ferenc (1649, Dés - 1716, Nagyenyed), professor and rector of the Protestant College of Nagyenyed, the famous Transylvanian humanist, medical doctor, poet, philosopher, church historian, heraldist. He studied in Dés (now Dej, Romania), Gyulafehérvár (now Alba Iulia, Romania), Kolozsvár (now Cluj-Napoca, Romania), Marosvásárhely (now Târgu-Mureş, Romania) and Nagyenyed (now Aiud, Romania). In the spring of 1672 he set off from Nagyenyed for a pedestrian trip abroad. He admired the Treasury in Dresden, and attended medical studies in Leipzig and Heidelberg. He completed his medical studies in Basel. In 1674 he became doctor medicus and was elected member of the board of the medical faculty. He returned to Nagyenyed in 1675. Between 1676 and 1690 he is the physician of the court of the Transylvanian princely couple. In 1678 he got a department in the College of Nagyenyed, extended in 1680 with Greek, physics, natural sciences and medical knowledge departments. Between 1681 and 1715 he was the rector of the College. Above all he cherished peace. He was a versatile writer. His medical book written in Hungarian, the PAX CORPORIS, i.e. “the peace of the body” was printed and published at Kolozsvár in 1690. This was dedicated to the target community: “for the benefit of the stupid poor”, it substituted the physician in the family. The rules of a healthy lifestyle were formulated also. The popularity of the book was proved by those eleven editions we know about. Another great work was the Hungarian-Latin, Latin-Hungarian dictionary (Lőcse, now Levoca, Slovakia, 1708). His memory is kept by a bust and plate in the courtyard of the Protestant College of Nagyenyed. The Hungarian postal service (Magyar Posta) released a stamp on his 350th anniversary. His life, work and importance were appreciated by a number of authors across centuries. An internet search on the terms “Pápai” + “Páriz” + “Ferenc” returns an important number of hits. Many foundations and associations are dedicated to his memory.

Vehicular communication is a cynosure in automotive industry these days. V2V communication is one of the types of vehicular communication which render lane change warning, emergency vehicle alert, intersection alert, congestion alert, payment at tolls etc. A simulation research on the utilization of vehicle to vehicle connectivity via different routing protocols in VANET, contemplating the instance of a city situation has been introduced in our paper in order to resolve the issue of traffic routing. A routing algorithm is proposed which firstly selects optimal path via carry and forward approach and then transmits information on that path and the proposed algorithm is then compared with contemporary routing protocols based on different QoS parameters like throughput, packet delivery ratio, delay which are measured using NETSIM simulator to evaluate the behaviour of dissimilar routing protocols. The proposed algorithm outperforms most of the simulation cases.

Research has conducted as an alternative form of advanced treatment in order to eliminate copper (Cu2+) heavy metal contained in electroplating industrial wastewater. The process is conducted biologically by utilizing the ability of mixed cultures of freshwater microalgae immobilized. The purpose of this study was to determine the removal efficiency for copper (Cu2+) using microalgae single and microalgae cultures mixed, determine the removal efficiency for copper (Cu2+) using mixed cultures microalgae which immobilized by alginate, and determine the influence of temperature and initial concentration of wastewater on the efficiency removal of copper metal (Cu2+) by mixed cultures of the immobilized microalgae. Microalgae are isolated from Setiabudi Reservoir, and purified in order to obtain Ankistrodesmus sp and Chlorella sp. These biosorbents then immobilized by adding alginate to form beads with a diameter of ± 0.5 cm. Artificial biosorbent cultivated in a growth medium Phovasoli Haematococcus Medium (PHM) in a series of batch cultures. The study consisted of three phases, namely the determination of biosorbent mobile and immobilized, optimization of temperature variations (25oC, 30oC and 35oC), and optimization of the initial concentration of wastewater (3 mg/l, 5 mg/l, 10 mg/ l, 15 mg/ l, and 15 mg l) at pH 4 and 120 minutes contact time. These used biosorbent was a single microalgae Ankistrodesmus sp and Chlorella sp and mixed cultures consisting of microalgae Ankistrodesmus sp and Chlorella sp with 1:1 ratio. The results prove that the removal efficiency for copper (Cu2+) by mixed cultures of microalgae was higher than either mobile or single immobilized. Copper (Cu2+) removal efficiency was proof depend on temperature process and the initial concentration of the wastewater. The optimal removal of copper (Cu2+) with immobilized biosorbent occurred at 30 °C with an initial concentration of waste by 17.808 mg /l with a value of 82.54% ± 0.11 for Ankistrodesmus sp; 83.66% ± 0.15 for Chlorella sp; and 86.39% ± 0.34 for a mixed cultures.
