Authors: Akgun Sakir , Kucuksayan Hakan , Ozes Osman N. , Can Ozge , Alikanoglu Arsenal S. , Yildiz Mustafa , Akca Hakan
Published: February 2019

Background:

Non-Small Cell Lung Cancer (NSCLC) is an aggressive cancer type due to high metastatic capacity. Nuclear Factor Kappa B (NF-κB) is a consistently active transcription factor in malignant lung cancer cells and has crucial significance in NSCLC progression. It is also implicated in the transcriptional regulation of many genes including microRNAs (miRNAs) that function as tumor suppressor or oncogene. It has been increasingly reported that several miRNAs defined as gene members are induced by NF-κB. The present study aimed to find novel miRNAs that are regulated by NF-κB.

Methods:

Chromatin İmmunoprecipitation Sequencing (ChIP-Seq) experiment and bioinformatic analysis were used to determine NF-κB-dependent miRNAs. Western blot analysis, quantitative real-time polymerase chain reaction (qRT-PCR), luciferase reporter gene assays were carried out to investigate the target genes of miRNAs. To determine biologic activity, transwell invasion and MTT assay were carried out on H1299 NSCLC cell line. miRNA expression level was evaluated in metastatic and non-metastatic tissue samples of NSCLC patients.

Results:

ChIP-Seq and qRT-PCR experiments showed that miR-548as-3p is transcriptionally regulated by NF- κB in response to Tumor Necrosis Factor-α (TNF-α) treatment. Then, we found that tumor suppressor Phosphatase and Tension homolog (PTEN) is a direct target of miR-548as-3p. Furthermore, miR-548as-3p mediates phosphatidylinositol-3-OH kinase (PI3K)/Akt pathway and NF-κB-implicated genes including Matrix Metalloproteinases 9 (MMP9), Slug and Zeb1. We further showed that miR-548as-3p increased invasiveness of NSCLC cells and was upregulated in metastatic tumor tissues compared to non-metastatic ones.

Conclusion:

All these findings provide a miRNAs-mediated novel mechanism for NF-κB signaling and that miR-548as-3p could be a biomarker for NSCLC metastasis.
Plasmid-Mediated Quinolone Resistance in Pseudomonas aeruginosa Isolated from Burn Patients in Tehran, Iran
Authors: Molapour Azam , Peymani Amir , Saffarain Parvaneh , Habibollah-Pourzereshki Narges , Rashvand Pooya
Published: February 2019

Introduction:

Plasmid-induced quinolone resistance has raised a great concern in the
treatment of serious infections worldwide. The aims of this study were to determine the antibiotic
susceptibility, the frequency of qepA, aac(6')-Ib and qnr genes by PCR and sequencing, and typing
of the resistant isolates using repetitive extragenic palindromic sequence-based PCR (REPPCR)
in Pseudomonas aeruginosa isolated from burn wound infections.

Methods:

In the current cross-sectional study, 149 P. aeruginosa were isolated from the burn
wound samples of patients admitted to Motahari hospital in Tehran, Iran, from February to December
2016. The bacterial isolates were identified using standard laboratory methods and their
antibiotic susceptibility to quinolones was evaluated using the standard Kirby-Bauer method, according
to the Clinical and Laboratory Standards Institute (CLSI) guidelines. The presence of
aac(6')-Ib, qepA, qnrA, qnrB4, qnrB and qnrS genes was assessed using PCR and sequencing
methods and clonal relationship of the resistant isolates was evaluated using REP-PCR method.

Results:

All (100%) isolates showed complete resistance to used quinolone compounds in this
study. The qnr and qepA genes were not found, but all (100%) isolates were positive for the presence
of aac(6')-Ib gene and the sequencing revealed that all (100%) belong to the aac(6')-Ib-cr
variant. REP-PCR showed that the studied isolates belonged to three distinct clones of A (77.9%),
B (18.1%), and C (4%).

Conclusion:

The findings of the present study indicated the presence of aac(6')-Ib-cr variant and
lack of the contribution of qnr and qepA in the emergence of resistance to quinolones in P. aeruginosa
isolated from burn patients. Considering the importance of clonal spread of these resistant
isolates and their significant role in the development of clinical infections, especially in patients
with burns, more attention should be paid to the prevention of the dissemination of these resistant
isolates.
Adrenergic Regulation of Macrophage-Mediated Innate/Inflammatory Responses in Obesity and Exercise in this Condition: Role of β2 Adrenergic Receptors
Authors: Ortega Eduardo , Gálvez Isabel , Martín-Cordero Leticia
Published: February 2019

Background:

The effects of exercise on the innate/inflammatory immune responses are crucially mediated by catecholamines and adrenoreceptors; and mediations in both stimulatory and anti-inflammatory responses have been attributed to them. Obesity and metabolic syndrome are included among low-grade chronic inflammatory pathologies; particularly because patients have a dysregulation of the inflammatory and stress responses, which can lead to high levels of inflammatory cytokines that induce insulin resistance, contributing to the onset or exacerbation of type 2 diabetes. Macrophages play a crucial role in this obesity-induced inflammation. Although most of the antiinflammatory effects of catecholamines are mediated by β adrenergic receptors (particularly β2), it is not known whether in altered homeostatic conditions, such as obesity and during exercise, innate/ inflammatory responses of macrophages to β2 adrenergic stimulation are similar to those in cells of healthy organisms at baseline.

Objective:

This review aims to emphasize that there could be possible different responses to β2 adrenergic stimulation in obesity, and exercise in this condition.

Methods:

A revision of the literature based on the hypothesis that obesity affects β2 adrenergic regulation of macrophage-mediated innate/inflammatory responses, as well as the effect of exercise in this context.

Conclusion:

The inflammatory responses mediated by β2 adrenoreceptors are different in obese individuals with altered inflammatory states at baseline compared to healthy individuals, and exercise can also interfere with these responses. Nevertheless, it is clearly necessary to develop more studies that contribute to widening the knowledge of the neuroimmune regulation process in obesity, particularly in this context.
A Randomized Controlled Trial of a Herbal Compound for Improving Metabolic Parameters in Diabetic Patients with Uncontrolled Dyslipidemia
Authors: Ghorbani Ahmad , Zarvandi Mahdi , Rakhshandeh Hassan
Published: February 2019

Objective:

The aim of this randomized controlled trial was to investigate the effects of a
polyherbal compound consisting of Aloe vera, black seed, fenugreek, garlic, milk thistle, and psyllium
on diabetic patients with uncontrolled dyslipidemia.

Methods:

Fifty patients with type 2 diabetes who had dyslipidemia in spite of statin therapy were randomly
allocated to two groups: control group (n = 25) receiving a conventional therapy with hypolipidemic
and hypoglycemic drugs and intervention group (n = 25) receiving both the conventional therapy
and the herbal compound (one sachet twice daily) for 12 weeks. Each sachet contained 300 mg of
Aloe vera leaf gel, 1.8 g of black seed, 300 mg of garlic, 2.5 g of fenugreek seed, 1 g of psyllium seed,
and 500 mg of milk thistle seed.

Results:

The levels of serum triglyceride, total cholesterol, low-density lipoprotein, and HbA1c
showed a significant in-group improvement in the intervention group. However, the effects of the
herbal compound on fasting blood glucose remained insignificant. The compound had no unwanted
effect on the kidney function parameters (urea, creatinine) and serum liver enzymes (alanine
aminotransferase and aspartate transaminase).

Conclusion:

The tested herbal compound, as an add-on to statin therapy, was effective in lowering the
serum lipids in diabetic patients with uncontrolled dyslipidemia.

Published: February 2019

Background:

There are several potential advantages in optimizing the initial events of osseointegration in the benefit of clinical outcome.

Objective:

The objective of the present study was to evaluate the behavior of osteoblastic cells on surfaces treated by double acid etching using HNO3 and H2SO4.

Methods:

Commercially pure titanium (grade 4) discs measuring 6 mm in diameter and 2 mm in thickness were used. The discs were divided into two groups: machined group and double acid-etched discs (HNO3 and H2SO4). Surface characteristics were assessed using Scanning Electron Microscopy. Pre-osteoblastic MC3T3-E1 cells were used for cell culture on the tested surfaces to assess proliferation, viability (MTT), as well as secretion (ELISA) and cytoplasmic expression (Western blot) of type I collagen.

Results:

The data obtained were analyzed using t-test or two-way ANOVA followed by Bonferroni’s test at 95% significance. The titanium surfaces showed average roughness values for the machined and treated surfaces of 0.29 and 1.16, respectively (p<0.05). An increase in cell proliferation was observed, which was corroborated by the viability assay. Both type I collagen secretion and intracellular expression were higher on the double acid-etched surface compared to the machine surfaces (p<0.05).

Conclusion:

Implant surfaces treated by double acid etching positively affected the early events of the interaction between titanium and osteoblastic cells, suggesting optimization of osseintegration.
A New Tooth Processing Apparatus Allowing to Obtain Dentin Grafts for Bone Augmentation: The Tooth Transformer
Authors: Minetti Elio , Berardini Marco , Trisi Paolo
Published: February 2019

Introduction:

Human dentin matrix could be considered an excellent alternative to autologous or heterologous bone graft. Autologous tooth graft has been proposed since 1967 when the osteoinduction properties of autogenous demineralized dentin matrix were discovered.

Methods:

The preparation technique to transform autologous teeth in suitable grafting material still represents the fundamental step of the whole procedure.

Aim:

The aim of the present study was to test an innovative medical device that could obtain tooth graft materials starting from the whole tooth of the patient. 15 consecutive cases of tooth grafting procedures were performed with a mean follow up period of 18 months.

Results:

In all cases, after 6 months of healing, the defects were almost completely filled by newly formed hard tissue. The new tissue was examined after 6 months, both from a radiological point of view by CBCT scans and from a clinical observation. It showed a compactness similar to the medium-density bone. No signs of inflammations were observed. No infective complications were recorded during the post-operative healing. No graft particles or grains were visible in the regenerated bone structure that appeared homogeneous and uniform.

Discussion:

The results of the present study showed favorable bony healing in guided regenerative surgery procedures using autologous tooth graft. Future studies with long follow up period are needed in order to better evaluate the potential of demineralized dentin autografts.

Published: February 2019

Introduction:

Due to its practicality in preparation and to have nutrients that satisfy hunger quickly, hamburger has become a product consumed by all popular classes. However, due to the considerable contents of saturated fat and sodium, consuming too much of this type of food can be harmful to human health.

Methods:

Aiming at the development of a healthier meat product with reduced saturated fat, a chicken burger with green banana biomass flour and passion fruit peel flour was formulated using herbal salt (a blend of coarse sea salt and herbs) as a substitute for sodium chloride. The influence of these substitutions on the physical and physicochemical characteristics of the developed product was evaluated. The flours produced were evaluated according to the analysis of: granulometry, water content, water activity and color.

Result and Conclusion:

The hamburger formulations were analyzed for quality parameters: texture profile, color, water content, ash, pH, acidity, lipids, chlorides, cooking yield and percentage of shrinkage. The hamburger enriched with green banana biomass flour was characterized by the lower lipid content but presented higher values for firmness and chewability. The addition of passion fruit peel flour as a partial fat substitute provided higher yields, while the green banana biomass meal resulted in a smaller shrinkage to the burger after cooking. The green banana biomass flour hamburger presented as a viable alternative for the ingestion of processed meat with reduction of sodium and fat.

Authors: Tyllianakis Minos , Panagopoulos Andreas , Fokas Konstantinos , Eleni Argyriadi , Megas Panagiotis
Published: February 2019

Background:

Van Nes Rotationplasty (VNRP) is a biological reconstructive surgical method for pediatric sarcoma, complex trauma or severe lower limb deficiencies that often gets overlooked due to cosmetic reasons and psychological aspects. We report a unique case of knee stiffness and severe scarring from burns treated with this technique in a young patient who had also amputated contralateral femur.

Case Report:

A 15-year-old boy was trapped in a fire 10 years ago and sustained extensive contractures on his left knee due to severe burns and also an above knee amputation on his right thigh. For 10 years the boy had never received rehabilitation or worn any prosthesis and he managed to move bearing mainly on his palms. On admission to our hospital Van Nes rotationplasty was preferred among other treatment options as the most suitable solution for him and was successfully performed without complications.

The patient had severe stiffness on his right hip and decreased muscle power in the VNRP leg but after intensive physiotherapy he was able to stand upright and walk again using custom made bilateral prostheses and crutches.

Conclusion:

VNPR is a reasonable option in severe contractures and scarring of the knee joint.

Published: February 2019

The purpose of this research is to know in depth how the dynamics of social control family and peers on adolescents who are at risk of drug abuse. Method: This research method using qualitative research method, which uses data collecting interviews and observation. Participant: This study focused on participants who are at risk of drug abuse with the following criteria: (a) willing to be a participant, (b) gender to male or female, (c) ± adolescents aged 15-18 years, (d) adolescents who are indicated are at risk of drug abuse. Result: The results of this study indicate that adolescents who are at risk of drug abuse are smoking and drinking. High risk factors cause adolescents to be at risk for drug abuse, ie family conflicts, negative parental models, involvement of negative activities with peers, and peer-to-peer conformity. This is supported by the weakness of protection factors in adolescent behavior at risk of drug abuse. Weak family controls supported by weak peer control will increase the risk rate for adolescent drug abuse behavior. This suggests that family and peer social controls are very influential to reduce the risk of adolescent drug abusers, especially in prevention and intervention.

El efecto de las comunidades virtuales de aprendizaje en la permanencia y aprendizaje del estudiante de la modalidad virtual del nivel medio superior de la UAS
Authors: Vizcarra Parra Faustino , Gómez Santos Saúl Alejandro , Mendoza Román José Manuel
Published: February 2019

Las comunidades virtuales de aprendizaje son utilizadas por los estudiantes para estar comunicados y apoyarse mutuamente. La aplicación WhatsApp ha demostrado ser una herramienta muy útil para la creación de dichas comunidades.

En este entorno, ocurren situaciones interesantes acerca del aprendizaje y permanencia en los cursos que los docentes deben conocer a fin de mejorar la mediación docente. En estas comunidades se da el aprendizaje dialógico: algunos

participantes manifiestas dudas y otros las responden argumentando sus respuestas sin imponer nada. Así que, para conocer lo que ocurre en estos espacios, se llevó a cabo una investigación, en la que se integra a un docente como estudiante pasivo, el cual solo registra las interacciones entre el resto de los alumnos, a la par que, en otra comunidad, el mismo docente funge como miembro activo que interactúa con los demás y registra las participaciones. El presente estudio muestra los resultados obtenidos a través del contraste de las interacciones de ambas comunidades virtuales para conocer su efecto en el aprendizaje de los estudiantes y su permanencia en un curso.

Metodología cualitativa en bibliotecología y ciencia de la información. Un análisis bibliográfico de artículos académicos
Authors: Hernández Salazar Patricia
Published: February 2019

El seguimiento del enfoque cualitativo para realizar investigaciones en las disciplinas bibliotecológica y de la información ha sido escaso. Una posible causa es su esencia basada en la relación directa con los sujetos/objetos de estudio y en las implicaciones para los investigadores en cuanto a la cantidad de datos y su adecuada interpretación y narración. El objetivo del presente artículo es establecer la situación que prevalecesobre la aplicación de métodos cualitativos en bibliotecología y ciencia de la información. El cumplimiento de este objetivo requirió abordar tres temas principales:la esencia del enfoque cualitativo, las implicaciones de seguirlo y un panorama de su empleo, mediante un análisis bibliográfico de artículos académicos. El resultado refuerza la idea de que hay poco interés por realizar estudios cualitativos.
Heidegger, lector de la retórica aristotélica
Authors: Escudero Jesús Adrián
Published: February 2019

El presente trabajo analiza la productiva asimilación heideggeriana de la retórica aristotélica que encontramos en sus lecciones de 1924, Conceptos fundamentales de la filosofía aristotélica, y su posterior repercusión en los análisis del uno cotidiano y de la habladuría en Ser y tiempo. Primero se presentan las líneas básicas de la interpretación heideggeriana temprana de los escritos prácticos y políticos de Aristóteles (1). Luego se perfila con más detalle su relectura en clave ontológica de la Retórica de Aristóteles, prestando una especial atención al plano de la comunicabilidad de las opiniones (2). Y, finalmente, se muestran los aspectos positivos y negativos contenidos en el fenómeno de la habladuría analizado en Ser y tiempo, un fenómeno que condensa buena parte de las interpretaciones de la retórica aristotélica (3).
Razón práctica y violencia en Paul Ricoeur
Authors: Gabriel Silvia Cristina
Published: February 2019

Dada la polaridad entre las teorías “legitimistas” (Weber) e “ilegitimistas” (Arendt) respecto de la violencia en la arena política, en este artículo se explora el aporte de Paul Ricoeur en torno al tema. Puesto que para este autor lo político es la realización de la intención ética, primero se abordará la dimensión ética y moral de la violencia. Después se ingresará en el dominio propiamente político donde Ricoeur defiende una dialéctica “asimétrica” entre los argumentos “ilegitimistas” y “legitimistas” en la cual los primeros adquieren razonabilidad dentro de un concepto “amplio” de violencia próximo al de Arendt. Por último, se abordará la dimensión temporal de la violencia presente en la memoria colectiva y en la historia. Se concluirá con un balance de los méritos y de las cuestiones parcialmente irresueltas en la obra de Ricoeur.
Virtudes, argumentación jurídica y ética judicial
Authors: Amaya Amalia
Published: February 2019

Según Manuel Atienza, la teoría de la argumentación jurídica se tiene que ocupar de responder tres preguntas: cómo analizar una argumentación, cómo evaluarla y cómo argumentar. Esta concepción de la teoría de la argumentación jurídica es, sin embargo, demasiado restrictiva. Además de proporcionar una respuesta adecuada a estas preguntas, una teoría de la argumentación jurídica debe ocuparse también de la cuestión de qué virtudes debe tener un juez para hacer buenas argumentaciones. La teoría de la argumentación jurídica está, por ello, íntimamente vinculada con una teoría de la ética judicial.
Réplica a “Cómo evaluar las argumentaciones judiciales” de Manuel Atienza
Authors: Cruz Parcero Juan Antonio
Published: February 2019

En esta réplica se analizan las ideas de Manuel Atienza sobre cómo evaluar la argumentación judicial. La crítica se enfoca en la afirmación de que, en cada ámbito del Derecho (legislativo, judicial, abogacía, etc.), los criterios de corrección son diferentes. Se sostiene, en cambio, que los criterios que sirven para el ámbito judicial son iguales a los criterios que rigen los argumentos de los abogados. Si bien los argumentos de los abogados buscan la persuasión, su éxito requiere que se cumplan los estándares usados por los jueces al evaluarlos. Donde sí cabe la distinción es respecto de la argumentación del legislador, pues en ese ámbito sus argumentos no dependen de las opiniones de los jueces al ser los propios legisladores autoridad en materia de interpretación de leyes.
Cómo justificar el veritismo

white, perlite, gypsum and fly ash were investigated. Densities, water
absorption ratios, ultrasonic velocities and thermal conductivity
coefficients of samples were determined. Furthermore, linear absorption
coefficient were measured by gamma ray saturation levels at 17.7, 26 and 60
keV energies. Thermal conductivity coefficients of the produced composites
were found to be in the range 0.0882- 0.0995 Kcal/mh?C. Egg white decreased
the linear absorption coefficients. Unit weights of samples were found to be
dependent on their contents. As gypsum rate increased, unit weight also
increased. As perlite rate increased thermal conductivity coefficient
decreased. As egg white decreased the linear absorption coefficient
decreased, also. The most important benefits of these types of materials are
their being impermeable and perfectly compatible with the environment. These
lighter type materials were/are compatible with Turkey and the Middle East
environment. Egg white has been resistant to radiation. Hence, it is highly
compatible with the environment. The compressive and flexural strengths of
mortars decreased with the use of egg whites in mortar. So, egg white
enhances the binding property of samples. In most cases, some organic and/or
inorganic additives are used as well, to improve the physical and mechanical
properties of mortar, such as egg whites and others. Finally, this study
shows that it is possible to produce an insulation material resistant to
sound and radiation by using egg white, perlite and fly ash. It is seen that
the samples incorporating egg white could be used at hospitals, military and
industrial facilities and shelters which are under radiation hazard.
Furthermore, this insulation materials will be put to use in industry in
Turkey after many experiments have been done on laboratory.

Glass as a material in architecture and civil engineering represents a
challenge, and it is often a material of choice for designers, used both for
the building interior elements as well as for cladding of building. The
paper has addressed specifically the glazed curtain wall fa?ades and the
earthquake-induced issues related to them. A review of the standing
standards and practice in this field are provided. The paper presents some
of contemporary solutions for damage mitigation of glazed building envelopes
caused by earthquakes, such as: solutions with clearances between glass and
its frame, earthquake-isolated curtain wall system, modified geometry of
glass corners and friction damping connectors.

Authors: Curcic Aleksandra
Published: February 2019

Sustainable and affordable technologies are an important aspect of
environment and energy efficiency. Environmental pollution in urban areas is
one of the causes for poor air quality. Gaseous emissions from daily traffic
are continuously increasing often exceeding the allowable concentration in
the atmosphere. The development of self cleaning materials photocatalytic
building materials-particularly when applied to facades, can contribute to
providing the clean the air and to improvement of sustainability levels.
They represents one of the most promising solutions for reducing air
pollutant concentrations in urban areas, proving to be really effective and
showing a real eco-sustainable value. The paper explains the mechanism of
self-cleaning of fa?ades, their types in architectural design and the
importance of their application.
The challenges of planning in the field of cultural heritage in Serbia
Authors: Nikovic Ana , Manic Bozidar
Published: February 2019

Serbia is characterized by a rich cultural heritage and cultural diversity,
as well as by a developed system of protecting cultural property. The
current trend is that of a constant increase of the number of registered
cultural properties under protection. Urban settlements in Serbia are
characterized by specific typological characteristics and recognizable
architectural typologies that are valuable architectural heritage as well as
an urban identity factor. Together, protected cultural property and
architectural heritage belong to a wider concept of urban heritage in the
sense comprised in the modern charters on the protection of cultural
heritage (HUL). The primary starting point of the paper is that the law and
plans in Serbia must become more sensitive to the context. In addition to
protecting registered property, the protection of buildings and other
structures that are not cultural heritage should also be introduced.
However, current planning practice in Serbia does not sufficiently recognize
cultural heritage in the wider sense of urban heritage, nor does it affirm
it as an important resource for sustainable development. By analyzing the
planning context, the problems and challenges in terms of institutional,
legal and governance frameworks, as well as planning methodologies, can be
identified. The paper is a contribution to the contextual analysis within
the National Strategy for the Sustainable and Integral Urban Development of
Serbia (currently developing within a wider team of experts), with the aim
of affirming the cultural potential of Serbia and incorporating the topic of
cultural heritage as a resource for sustainable development into Serbia?s
development programs and projects.
Greenways as an element of urban planning: Banja Luka case study
Authors: Trkulja Tanja , Dosenovic Ljiljana , Matic Nikola
Published: February 2019

The continuous presence of the landscape concept in planning and design of
the Banja Luka area until the end of the 20th century influenced the
formation of the identity of Banja Luka as a green city. However, in the
last twenty years, there is an absence of the green city concept from
planning and designing of Banja Luka's area. In order to improve the state
of urban greenery and achieve the satisfactory condition of the endangered
landscape elements, this paper re-examines their significance for the city.
The green infrastructure has ecological, social and aesthetic functions and
it becomes an imperative in defining the strategic goals of a sustainable
city. The study showed, that there are possibilities of increasing the size
of green areas and improving the quality of green areas in the built city
tissue. One of those possibilities is transformation of the existing
brownfields into green areas. From the perspective of urban planning, the
purpose of this paper is to point out the possibility of implementing the
greenways in the city structure for the case study in Banja Luka. In this
context, the research focuses on the area of the former Incel factory and
the ability to transform the abandoned railways into a greenway. In this
research, the sustainable spatial development context of Banja Luka is
regarded as a permanent category which includes, among the others, the
ambient values, the spirit of the place and the features of a green city are
important for the city's inhabitants.
Traditional gates in the Pirot area villages: Relationship to the architectonic heritage
Authors: Turnsek Branko , Djordjevic Isidora
Published: February 2019

Gates represent the first architectonic element visually encountered in a
rural household, and that, to a great extent, defines perception of a rural
environment. Most often they are simply made, with or without decorative
elements, made from the locally available materials, serving the elementary
needs of a rural household. However, their position provides them with a
multidimensional character, not only physical, but also symbolical. In this
way, they become an important segment of architectonic heritage whose
existence testifies the diversity of vernacular tradition and
characteristics of an area. This paper analyses the appearance, function,
materialization and structural design of old traditional gates in the Pirot
area villages, in an attempt to emphasize the need to preserve them as
testaments of cultural-historical identity of this area.

Application of membrane technology in the treatment and analysis of triazine pesticides in water
Authors: Brankovic Milica , Bojic Aleksandar , Andjelkovic Darko , Andjelkovic Tatjana
Published: February 2019

The quality of consumable water is decreasing due to increasing water
pollution caused by the production and use of human-made chemicals. A
significant part of these chemicals are pesticides from the class of
triazines since they are widely used in agriculture as herbicides. Water
treatment techniques mainly rely on separation science, where the membrane
technology has been identified as the most useful. Membrane processes used
in water treatment are microfiltration, ultrafiltration, nanofiltration and
reverse osmosis. In general, the pollutant retention/rejection by membranes
depends on the physicochemical properties of the membrane i.e. membrane
material, porosity, pore size and on the properties of the pollutant
molecule i.e. size, length, width, molecular weight, hydrophobicity or
dipole moment. The pollutant retention also depends on the feed-water
composition (organic matter and salt presence, solute concentration, water
pH). Thus, effective water treatment depends on the selection of an
appropriate type of membrane for a particular type of pollutants. Membrane
technology is also significant because it is used in polluted water
analysis, more precise as a part of a liquid-phase or solid-phase
microextraction. Among several developed membrane-based microextraction
methods, in triazine polluted water analysis common are membrane-protected
solid-phase microextraction and hollow-fiber liquid-phase microextraction.
In this field, researchers tend to achieve membrane-pollutant compatibility
through the synthesis of polymeric materials with molecular recognition
properties i.e. through a technology called molecular imprinting.
Single electron capture into arbitrary states of bare projectiles from multi-electron targets
Authors: Milojevic Nenad , Mancev Ivan
Published: February 2019

The prior form of four-body boundary-corrected first Born (CB1-4B) method is
applied to calculate the total cross sections for single electron capture
from the Kshell of multi-electron atoms (C, N, O, Ar) by fast projectiles
(H+, He2+and Li3+). All calculations are carried out for electron capture
into the arbitrary n, l, and m final states of the projectiles. The present
results are found to be in very good agreement with the available
experimental data at intermediate and high impact energies.
