MECHANICAL PROPERTIES OF CEMENT MORTAR WITH GRAPHENE OXIDE
Authors: KRYSTEK Małgorzata 
Published: May 2019

Abstract
These days, nanotechnology has already influenced many fields of science and technology, including civil engineering. Cementitious composites incorporating various nanomaterials have emerged as novel materials with improved microstructure, mechanical properties and durability. Over the past decades, graphene oxide has appeared as one of the most promising nanomaterials for civil engineering applications. However, the effect of graphene oxide addition on the properties of cementitious composites has not yet been fully investigated. The paper presents the studies on the mechanical properties of cement mortar reinforced with the 0.03 wt.% of graphene oxide (dosage by weight of cement). Graphene oxide proved to accelerate the cement hydration, in particular at the early stages of mortar hardening, hence improving the mortar performance during mechanical tests. The significant enhancement of the flexural, cubic and cylindrical compressive strength has been reported, thus showing the great nanotechnology potential for concrete structures.
EVALUATION OF ECOLOGICAL CONCRETE USING MULTI-CRITERIA ECOLOGICAL INDEX AND PERFORMANCE INDEX APPROACH
Authors: KUBISSA Wojciech , JASKULSKI Roman , CHEN Jiajian , NG Pui-Lam , GODLEWSKA Wioletta , REITERMAN Pavel 
Published: May 2019

Abstract
This paper proposes a new method of rational and quantitative assessment of ecological concrete in terms of the ecological impact and engineering performance. The concrete mix is evaluated through the multi-criteria Ecological Index (EI) and Performance Index (PI) approach. The EI accounts for the impact of the concrete on environment including the carbon emission and raw materials usage, whereas the PI accounts for the engineering performance of the concrete such as compressive strength and water sorptivity. Depending on the applications of the concrete, different criteria may be chosen for the evaluation. Concrete mixes reported in the literature comprising different types of cement, supplementary cementitious materials and aggregates are analyzed to illustrate the applicability of the proposed multi-criteria assessment method. It is shown that the proposed method is able to effectively reflect the concurrent ecological impact and engineering performance of concrete mixes, and hence facilitate rational design of ecological concrete to suit practical engineering applications.
THE EFFECTS OF DEAD LOADS IN CANTILEVER CONCRETING BRIDGES
Authors: MACHELSKI Czesław 
Published: May 2019

Abstract
Cantilever concreting technology is one of the modern methods of constructing concrete long-span bridges. Characteristic feature of those bridges is the long-term span deflection resulting from the rheological processes in the concrete and in the pre-tensioning steel. It can also be caused by the material deterioration, e.g. concrete cracking, as well as the changes in the bridge structure, such as the support settlements. The aggregate result of bridge exploitation are the changes in its grade line, considered in this paper as the bridge span deflection line. The aim of the paper is the assessment of the internal forces on the basis of the bridge span deformation. Furthermore, an algorithm for the correction of the deflection function determined on the basis of surveying measurements (low precision measurements) is proposed. It is characterized by a significant improvement of the computational results, and it hardly “smoothens” the primary measurement results. The algorithm can be used to analyse the selected part of the bridge structure, e.g. the longest span. The paper proposes a universal coefficient of cantilever deflection, which is calculated on the basis of the cantilever joint moment when the final static scheme of the bridge is created. It can be used for the comparative analyses of various bridges. The value of the coefficient is dependent on the geometry of the cantilever box cross-section only.

Authors: MUCHA Walter , ŻELIŃSKI Jacek 
Published: May 2019

Abstract
One of the basic documents of the Environmental Impact Assessment (EIA) procedure is the Environmental Impact Report. It contains information obtained during the investor’s assessment of any impact on the environment that may be caused by the object – also from the side of construction works at the investment stage. The authors, on the basis of nitrogen dioxide concentration data obtained from continuous, multi month measurements carried out with the use of the OPSIS device over the diametrial route DTŚ construction site in Gliwice, have evaluated the NO2 emission impact on the atmospheric air at the construction phase. The measurements made by the authors enabled in verifying the correctness of the assessments and comments regarding the impact of construction works conducted on the route DTŚ on the atmospheric air in the construction phase, contained in the Environmental Impact Report.

Published: May 2019

Abstract
Coconut fiber was chemically modified by NaOCl/NaOH, and then was composited through a cross-linking reaction with glutaraldehyde. The chitosan/coconut fiber (CTS/CF) composite membranes were prepared at various ratios of coconut fiber (CF) and then tested to determine their ability to eliminate aqueous heavy metals. The results showed that CTS/CF composite membranes having CF ratio of 80 wt% exhibited good mechanical strength as 89.8 MPa. In the elimination experiment of heavy metal ions, the CTS/CF 20/80 also showed that the removal capacity of Cu (II) and Pb (II) were over 90%.

First report of the dagger nematode Xiphinema pachtaicum on onion in Morocco
Authors: Mokrini Fouad , Dababat Abdelfattah 
Published: May 2019

Abstract
In 2018, during a survey in Souss region of Morocco, the dagger nematode Xiphinema pachtaicum was found parasitizing onion, (Allium cepa L.). The populations of dagger nematode were identified on the basis of their morphological and morphometric characters and by sequencing and analysing the D2D2 region of 28S rRNA. Microscopic observation of females demonstrated the occurrence of Xiphinema pachtaicum on onion. The 28S D2D3 sequences shared 99 to 100% similarity with sequence corresponding to X. pachtaicum in GenBank. To our knowledge this is the first report of Xiphinema pachtaichum infecting onion in Morocco.
Using Microemulsion as Carrier for Drug Transdermal Delivery: The Effect of Surfactants and Cosurfactants
Authors: Lu I-Ju , Fu Yaw-Syan , Chang Wen-Yu , Wu Pao-Chu 
Published: May 2019

Background:
The purpose of this study was to evaluate the effect of types of surfactants and cosurfactants
on physicochemical properties and permeability of sumatriptan-loaded microemulsions through rat skin.

Methods:
Different types of surfactants and cosurfactants were used to prepare drug-loaded microemulsions. The
physicochemical characters and permeability parameters of these formulations were measured.

Results:
The experimental microemulsions with varying components had small droplet size ranging from 24.6 nm
to 2568.8 nm, low viscosity ranging from 7.49 to 43.34 cps and significant permeation enhancement ratio ranging
from 23.0 to 98.6 when compared to the control group.

Conclusion:
The composition and proportion of surfactants and cosurfactants were key factors for the physiochemical
properties of drug-loaded microemulsions. The cumulative transdermal amount of the microemulsion
containing mixture surfactant of Laureth-3/Laureth-23 was higher than that of the microemulsion with a mixture
of Tween 80/Span 20. In the selected cosurfactant, diethylene glycol monoethyl ether (DEGMEE) showed highest
permeation enhancement. Thermodynamic stability tests revealed that the experimental microemulsion was a
stable enough formulation to be considered as a suitable carrier for sumatriptan.
Developing Stress Assessment forms for Thai Cancer Patients: The Thai Version of the Modified Symptoms of Stress Inventory (Modified SOSI)
Authors: Sumneangsanor Tipsuda , Ruchiwit Manyat , Weglicki Linda 
Published: May 2019

Background:
Cancer is a progressive illness that often has a prolonged treatment time
and that severely impacts a person’s quality of life. In Thailand, approximately 113,000 new cancer
patients are diagnosed each year. Furthermore, cancer patients also have a high mortality rate
of 90%, indicating that cancer is a major health problem both in Thailand and around the world.
Physical manifestations of cancer include pain in the organs where cancer has already spread and
side effects of treatment, such as chemotherapy and radiation, which adversely impact the mental
state of cancer patients. Increased stress often results in other subsequent health conditions. Thus,
identifying stress quickly and promptly in cancer patients through proper stress management is
important.

Objective:
To develop and monitor accurate stress evaluation according to the self-perceptions (Thai
version of the Modified Symptoms of Stress Inventory, Modified SOSI) of cancer patients in Thailand.

Research Methodology:
This study consists of three steps according to the research guidelines of
Wongwiwatthananukit, Newton, and Popovich (2002): (1) the process of creating and developing
tools; (2) the process of reviewing questions concerning the tools by experts; and (3) testing procedures
for the use of the tools.

Results:
Content consistency using Cronbach’s alpha coefficient from 30 samples were determined
to be .906. Investigation of the construct validity of the SOSI found that the relationships indicated
in stress consisted of physical, mental, and behavioral. Significant relationships between these three
aspects were determined by the Kaiser-Meyer-Olkin (KMO) measure of sampling as adequacy = 0.80,
and Bartlett’s test of sphericity gave statistical significance at 0.05. The most important indicator
was the physical, followed by the mental, while the behavioral had the least weight importance.

Conclusion:
The results of this study confirm that the Thai version of the Modified Symptoms of
Stress Inventory (Modified SOSI), comprising 30 questions, was able to evaluate stress, including
physical, mental and behavioral responses to stress. This inventory was considered concise and appropriate
for cancer patients and can be used with other populations.
Allergic Contact Dermatitis to Fentanyl TTS with Good Tolerance to Systemic Fentanyl
Authors: Rojas-Pérez-Ezquerra Patricia , Micozzi Sarah , Torrado-Español Ines , Rodríguez-Fernández Ana , Albéndiz-Gutiérrez Vicente , Noguerado-Mellado Blanca 
Published: May 2019

Background:Fentanyl is primarily an opioid agonist. It is frequently used in general anesthesia as a potent analgesic. It can be administered either orally, transdermally or systemically. Adverse effects due to opium alkaloids are usually because of a non-specific histamine release. Only in a few cases, a true allergy mechanism could be involved. Immediate reactions to opioids are most frequent than delayed reactions. In the past years, delayed reactions have increased in frequency because of the wide use of Transdermal Therapeutic System (TTS) with several opioids for its potent analgesic properties.Objective:The objective was to study delayed reaction to fentanyl TTS and cross-reactivity with other opioids.Methods:A 52-year-old man with a diagnosis of pancreatic cancer who began treatment for a bone metastases pain with fentanyl TTS, at a dose of 50 micrograms per hour (mcg/h) is the subject of the study. After 10-15 days of treatment, he developed an itchy papulovesicular rash in the application site of the fentanyl TTS. Afterward, eczema and superficial desquamation just on the application site of the patch were observed. He changed several times the site of application, but always developing the same symptoms in every single application. Later on, he tolerated other opioids such as oral morphine or tramadol. An allergy workout was performed. We performed Patch Tests (PT) with fentanyl at a concentration of 10% in aqua (aq) and with buprenorphine 10% aq., in order to investigate probable crossreactivity among other topical opioids.Results:Readings were recorded at day 2 (D2) and day 4 (D4), with positive PT only with fentanyl at D2 (+++) and D4 (+++). We decided to perform a single-blind challenge test with buprenorphine 35 mcg/h in TTS, with a negative result. At this moment, fentanyl TTS was replaced by buprenorphine TTS, with good tolerance.Conclusion:We present the case of Allergic Contact Dermatitis (ACD) due to hypersensitivity to fentanyl with good tolerance to buprenorphine. Positive PT in this patient suggests a type IV hypersensitivity mechanism. Allergic reactions to opioids are frequently immediate, but delayed reactions could appear, especially when the drug is administered topically.
Polymethylhydrosiloxane Coating Enhanced Corrosion Resistance of Hydrofluoric Acid Treated Mg Bio-implant Material in Simulated Body Fluid Solution
Authors: Bharti Manjubala , Sahu Ranjan K 
Published: May 2019

Background:
Deceleration of the corrosion rate of Mg by surface chemical method via
hydrofluoric acid treatment has a special interest because it is a simple, cost-effective, and efficient
method for the coating of interior as well as the exterior part of any size and shape of implant
material. However, conversion coating by hydrofluoric acid treatment fails to produce a
long-term stable coating of Mg in ionic solutions caused by the formation of cracks on the surface
during the process. Consequently, the corrosive ions of the SBF solution enter through the cracks
that accelerate the dissolution by local galvanic corrosion. On the above view, we aim to develop
a simple strategy for enhancement of corrosion resistance of the hydrofluoric acid treated Mg bioimplant
material.

Methods:
This method is comprised of dip coating of hydrofluoric acid treated Mg sample in the
polymethylhydrosiloxane followed by curing at 170°C for 30 min. The samples were characterized
by electron probe microanalysis, X-ray photoelectron spectroscopy and electrochemical test.

Results:
The electrochemical test results reveal that the corrosion rate of the coated Mg sample in
the simulated body fluid solution is decreased by more than 8500 times than the bare sample. The
long term immersion data indicate that the chemical resistance of the coated Mg sample in the
SBF solution even after 25 days is better than the bare Mg metal.

Conclusion:
Polymethylhydrosiloxane coating is efficient to enhance the corrosion resistance of
hydrofluoric acid treated Mg metal in simulated body fluid solution.
Young People Seeking Help Online for Mental Health: Cross-Sectional Survey Study
Authors: Pretorius Claudette , Chambers Derek , Cowan Benjamin , Coyle David 
Published: May 2019

Background
Young people are particularly vulnerable to experiencing mental health difficulties, but very few seek treatment or help during this time. Online help-seeking may offer an additional domain where young people can seek aid for mental health difficulties, yet our current understanding of how young people seek help online is limited.

Objective
This was an exploratory study which aimed to investigate the online help-seeking behaviors and preferences of young people.

Methods
This study made use of an anonymous online survey. Young people aged 18-25, living in Ireland, were recruited through social media ads on Twitter and Facebook and participated in the survey.

Results
A total of 1308 respondents completed the survey. Many of the respondents (80.66%; 1055/1308) indicated that they would use their mobile phone to look online for help for a personal or emotional concern. When looking for help online, 82.57% (1080/1308) of participants made use of an Internet search, while 57.03% (746/1308) made use of a health website. When asked about their satisfaction with these resources, 36.94% (399/1080) indicated that they were satisfied or very satisfied with an Internet search while 49.33% (368/746) indicated that they were satisfied or very satisfied with a health website. When asked about credibility, health websites were found to be the most trustworthy, with 39.45% (516/1308) indicating that they found them to be trustworthy or very trustworthy. Most of the respondents (82.95%; 1085/1308) indicated that a health service logo was an important indicator of credibility, as was an endorsement by schools and colleges (54.97%; 719/1308). Important facilitators of online help-seeking included the anonymity and confidentiality offered by the Internet, with 80% (1046/1308) of the sample indicating that it influenced their decision a lot or quite a lot. A noted barrier was being uncertain whether information on an online resource was reliable, with 55.96% (732/1308) of the respondents indicating that this influenced their decision a lot or quite a lot.

Conclusions
Findings from this survey suggest that young people are engaging with web-based mental health resources to assist them with their mental health concerns. However, levels of satisfaction with the available resources vary. Young people are engaging in strategies to assign credibility to web-based resources, however, uncertainty around their reliability is a significant barrier to online help-seeking.

Published: May 2019

La zona costera de la Patagonia austral, caracterizada por un régimen macromareal, permite el desarrollo de extensas marismas tanto en estuarios como en bahías, que han sido muy poco estudiadas. Con el objetivo de caracterizar las marismas del sur de Santa Cruz, identificar las principales asociaciones vegetales que las componen y analizar las variaciones de la biomasa vegetal en relación al nivel de marea y la época del año, se realizaron muestreos en primavera (noviembre 2015), verano (febrero 2016) e invierno (agosto de 2016) en la bahía San Julián y los estuarios de los ríos Santa Cruz, Coyle y Gallegos. Los muestreos se realizaron empleando un diseño aleatorio estratificado, dividiendo la marisma en tres niveles: alta, media y baja. Se recolectaron seis muestras de 0,25 m2 en cada nivel y se determinó el porcentaje de cobertura de cada especie y su biomasa aérea (peso seco). Se determinó también la granulometría y la materia orgánica del sedimento (%). Los datos se analizaron mediante ANOVA factorial (sitios, nivel, estación del año). El sustrato en todas las localidades y niveles estuvo constituido principalmente por limos-arcillas (54 a 88%) y arena fina (20 a 44%). La materia orgánica varió entre 4,5 y 7,1%. Se registraron cinco especies vegetales: Sarcocornia perennis, Puccinellia glaucescens, Suaeda argentinensis, Limonium brasiliense y Spartina sp. S. perennis fue la especie dominante en casi todos los sitios y niveles, con excepción de la marisma alta y la marisma media de Bahía San Julián, donde codomina junto a Limonium brasiliense, y la marisma baja del estuario del río Santa Cruz, donde codomina junto a Spartina sp. La biomasa vegetal aérea total alcanzó su valor máximo (1700 g m-2) durante el verano en la marisma baja del estuario del río Gallegos y correspondió en su totalidad a S. perennis. El valor más bajo de biomasa total (177 g m-2) fue registrado en la marisma alta de Bahía San Julián durante el invierno y correspondió en un 33,8% a S. perennis. La cobertura de S. perennis varió entre 23 y 100%, siendo siempre mayor en la marisma baja. Spartina sp. se encontró únicamente en la marisma baja del estuario del río Santa Cruz, sitio que constituye el registro más austral para esta halófita en la costa Argentina.
