Evaluation, Analysis and Perception of Sustainable Forest Management Through the Lens of the PEFC Forest Certification Using Two Case Studies in Sicily
Authors: Lombardo E. , Maetzke F.G.
Published: March 2019

Sustainable forest management has reached a common understanding between scientific and technical definitions. A series of criteria and indicators have been implemented for monitoring the effectiveness of the management in functional and structural terms, and to evaluate its effects on ecosystem services of forests. Currently, Sicily has no forest areas with certification of sustainable forest management and in order to evaluate the diffusion of knowledge of certification schemes and their importance in SFM, a questionnaire survey was carried out during a foresters' workshop on the island. The possibility of applying the criteria and indicators of PEFC certification of sustainable forest management is analyzed in two case studies, representative of Sicilian forest ecosystems. This analysis highlights the main weaknesses related to current management practices and inadequate consultation with stakeholders. Some critical aspects of the certification process are discussed, highlighting possibilities and difficulties.
On-Demand Digital Economy: Can Experience Ensure Work and Income Security for Microtask Workers?
Authors: Rani Uma , Furrer Marianne
Published: March 2019

Digital labour platforms have been increasingly gaining popularity over the past decade. In particular, there has been much debate about workers’ motivations and working conditions on microtask platforms. There exists little evidence on whether dependence on digital microtask platforms provides workers with work and income security in the long term and whether it provides opportunities for skill development. This paper explores the extent to which the seemingly flexible platform work ensures work and income security and provides opportunities for skill development for workers with different levels of experience, based on novel survey data collected on five globally operating microtask platforms and in-depth interviews with workers. The findings show that despite high financial dependence on this work, returns to experience on the platform are meagre in terms of earnings, and highly experienced workers face the same risks as new entrants with regard to discrimination, high work intensity, lack of autonomy and control over work, and social protection. There is also a skills gap between the nature of tasks available on these microtask platforms and the workers’ education levels. Finally, experience does not ensure that workers have the opportunities to undertake complex and challenging tasks, and the possibilities to develop their skills and improve career prospects are limited.

A successful transition of renal transplant recipients from pediatric to adult care requires a structured, need-adapted and multidisciplinary approach to preserve renal graft function during this critical period of life. In this article we present our clinical protocol for transition from pediatric to adult care, which we developed on the basis of the International Society of Nephrology (ISN)/International Pediatric Nephrology Association (IPNA) consensus guidelines influenced by our own experience. This transition program was established in our center in July 2017. The entire transition process is structured and accompanied by a transition key worker (social worker). From 12 years of age we train pediatric renal transplant recipients in medical knowledge, self-management skills and networking with self-help groups. The training is adapted to the individual patient‘s intellectual ability, lasts about 10 years and takes place with increasing intensity. Repeatedly we perform standardized informational interviews and check patient’s knowledge of transplant-related topics. Psychosocial and educational issues are evaluated concomitantly. The actual transfer takes place in a pediatric-adult-transition clinic. Relevant medical and psychosocial aspects are discussed and the future treatment regimen is established. The date of transfer is adapted to the individual patient’s need; it varies between 18 and 24 years of age. In periods of increased risk for non-adherence the transfer is postponed to intensify the efforts for training and assistance. After transfer a standardized evaluation of each individual patient takes place focusing on medical and psychosocial issues and on satisfaction with the transition process. Collection of these data is still in progress and will be analyzed systematically at a later stage in order to evaluate the impact of this new transition program on the stability of transplant function. That analysis might serve as a basis for negotiations about refunding with health insurance companies.

Published: March 2019

Poor uptake of nutrients not only deteriorates the quality but also the yield of horticultural crops. Among various macro and micronutrients, the role of K, Ca and B is very important. Therefore, balanced application and uptake of K and Ca and B can improve the quality and yield of mango trees. So, a field study was conducted with the hypothesis that combined application of K and Ca along with B would be effective to improve yield and quality of Mango cv. Summer Bahisht (SB) Chaunsa. There were two sources of Ca(CaCl2 and Ca(NO3)2) and three sources of K(KNO3, K2SO4 and K-Citrate) combined with boric acid (BA). All Ca and K sources were applied at the rate of 1% while BA was applied at 0.2%. As compared to control, a significant improvement in fruit set panicle-1 (35.7% and 50.0%), fruit retention (125% and 40%), shelf life (73.3% and 36.6%), total soluble solids (35.1% and 40.6%) and fruit yield (52.5% and 49.2%) in 2016 and 2017 respectively, confirmed the effectiveness of KNO3 (1.0%) + BA (0.2%). Between CaCl2 and Ca(NO3)2, application of Ca (NO3)2 was found more efficacious regarding improvement of quality and yield of SB Chaunsa. It is concluded that to improve the quality and yield of Mango cv. SB Chaunsa, KNO3 (1.0%) + BA (0.2%) is the best nutrients combination, and Ca(NO3)2 is a better option as compared to CaCl2.

Authors: Baraka Kim , Melo Francisco S. , Veloso Manuela
Published: March 2019

Due to their predictability, controllability, and simple social abilities, robots are starting to be used in diverse ways to assist individuals with Autism Spectrum Disorder (ASD). In this work, we investigate an alternative and novel research direction for using robots in relation to ASD, through programming a humanoid robot to exhibit behaviors similar to those observed in children with ASD. We designed 16 ‘autism-like’ behaviors of different severities on a NAO robot, based on ADOS-2, the gold standard for ASD diagnosis. Our behaviors span four dimensions, verbal and non-verbal, and correspond to a spectrum of typical ASD responses to 3 different stimulus families inspired by standard diagnostic tasks. We integrated these behaviors in an autonomous agent running on the robot, with which humans can continuously interact through predefined stimuli. Through user-controllable features, we allow for 256 unique customizations of the robot’s behavioral profile.We evaluated the validity of our interactive robot both in video-based and ‘in situ’ studies with 3 therapists. We also present subjective evaluations on the potential benefits of such robots to complement existing therapist training, as well as to enable novel tasks for ASD therapy.
Evaluation und Justierung eines neuartigen, hochfrequent fokusabstandsmodulierten, fasergekoppelten, konfokalen Punktsensors für axial geregelte Oberflächenmessungen mit einem Nanokoordinatenmessgerät

Published: March 2019

In diesem Artikel wird ein neues Messverfahren zur Oberflächenmessung bei gleichzeitiger axialer Regelung des Arbeitsabstandes eines hochfrequent fokusabstandsmodulierten, fasergekoppelten, konfokalen Punktsensors in einem Nanokoordinatenmessgerät (NMM-1) [T. Hausotte, B. Percle, and G. Jäger. Meas. Sci. Technol., 2009] vorgestellt. Während bei diesem Verfahren alle bekannten Vorteile der Konfokaltechnik beibehalten werden, stellt die innovative Kombination einer fasergekoppelten Beleuchtung und Detektion mit einer akustisch getriebenen, modulierbaren Flüssigkeitsgradientenlinse (engl. tuneable, acoustically driven gradient-index fluid lens, Abk. TAG-Linse) [Tag Optics Inc. Datasheet, 2013] zur hochfrequenten Abstandmodulation des Fokus zusammen mit einer neuartigen Signalverarbeitung auf Basis einer Lock-in-Verstärkung eine wesentliche Verbesserung dar. Durch die Anordnung und Auswertung ergibt sich im Gegensatz zu konventionellen konfokalen Punktsensoren eine nahezu lineare Kennlinie, wobei die Richtung der Abweichung der Messobjektoberfläche relativ zur Fokusebene des Objektivs eindeutig bestimmt werden kann. Es wird insbesondere die Verwendung des Sensors sowie die Nutzung der resultierenden Kennlinie zur Regelung der Oberflächenposition in einem Nanokoordinatenmessgerät gezeigt. Im Gegensatz zum Verfahren konventioneller Konfokalsensoren, bei der lateral flächenhafte Abtastungen auf vielen diskreten axialen Höhen durchgeführt werden, um daraus für jeden lateralen Messpunkt durch eine Maximalwertsuche einen Höhenwert zu ermitteln, kann durch die gezeigte Nachregelung eine Oberflächenerfassung durch eine einzige laterale Abstastung erfolgen. Die sich daraus ergebende immense Zeitersparnis führt zusätzlich zu Messungen mit geringeren thermischen Driften und geringeren Messabweichungen.

The oligoadenylate-synthetase (Oas) gene locus provides innate immune resistance to virus infection. In mouse models, variation in the Oas1b gene influences host susceptibility to flavivirus infection. However, the impact of Oas variation on overall innate immune programming and global gene expression among tissues and in different genetic backgrounds has not been defined. We examined how Oas1b acts in spleen and brain tissue to limit West Nile virus (WNV) susceptibility and disease across a range of genetic backgrounds. The laboratory founder strains of the mouse Collaborative Cross (CC) (A/J, C57BL/6J, 129S1/SvImJ, NOD/ShiLtJ, and NZO/HlLtJ) all encode a truncated, defective Oas1b, whereas the three wild-derived inbred founder strains (CAST/EiJ, PWK/PhJ, and WSB/EiJ) encode a full-length OAS1B protein. We assessed disease profiles and transcriptional signatures of F1 hybrids derived from these founder strains. F1 hybrids included wild-type Oas1b (F/F), homozygous null Oas1b (N/N), and heterozygous offspring of both parental combinations (F/N and N/F). These mice were challenged with WNV, and brain and spleen samples were harvested for global gene expression analysis. We found that the Oas1b haplotype played a role in WNV susceptibility and disease metrics, but the presence of a functional Oas1b allele in heterozygous offspring did not absolutely predict protection against disease. Our results indicate that Oas1b status as wild-type or truncated, and overall Oas1b gene dosage, link with novel innate immune gene signatures that impact specific biological pathways for the control of flavivirus infection and immunity through both Oas1b-dependent and independent processes.

Authors: Malykhina Irina V.
Published: March 2019

Introduction. The article presents the introduction of the hybrid musical instrument (disklavier) into the system of Russian music education. This new instrument has appeared relatively recently. It is relevant to study the world experience of using the hybrid piano and to analyze the prospects for applying it in the field of Russian piano performance. The purpose of the article is to analyze the specifics of using the hybrid musical instrument with additional equipment among students of higher educational institutions of Moscow.
Materials and Methods. In the experimental part of the study, the American method of K. Riley was used. The additional techniques of working with disklavier and additional equipment based on Riley’s method were developed and applied. An activity criterion was chosen to assess the professional ski lls of students.
Results. Based on pedagogical observation and interviewing, it was established that the use of a hybrid musical instrument and additional equipment improves the intellectual, research and creative abilities of students. The disklavier allows students to hear themselves in acoustic format from the position of a teacher. The instrument provides auditory and visual analysis of performance. The students can compare their feelings from the game with the exact data recorded by the disklavier and make changes to the record without losing its quality.
Discussion and Conclusion. The study demonstrates the effectiveness of the use of specially developed methods of working with the disklavier and additional equipment. More work will need to be done to determine the influence of new technologies in the class of a special piano and chamber ensemble at various levels of education. This study may be of interest both for students and teachers of the piano department at secondary special and higher educational institutions.

Authors: Faddeev Alexander O. , Pavlova Svetlana A. , Nevdakh Tatiana M.
Published: March 2019

Introduction. For the purposes of this article, geodeformation processes mean processes associated with deformations arising from the movement of species and blocks of the lithosphere at various depths, including surfaces. The objective is to reconstruct geodynamic stress fields, which cause modern shifts and deformations in the Lithosphere. A mathematical model and software for estimating the stress-strain state of the Earth Lithosphere are considered.
Materials and Methods.For mathematical modeling of stresses, isostatically reduced data on abnormal gravitation field were used. The methods of continuum mechanics and methods of the theory of differential equations were used to design a model for estimating the stressstrain state of the Earth Lithosphere. For processing input, intermediate and outcoming data, the Fourier transform method of spectral analysis for constructing grid functions and spectral-temporal method were used. To model for the stress-strain state of the Lithosphere globally, stress calculation was corrected on the basis of sputnik-derived velocity data at the surface of the earth crust. The data on the rates of horizontal and vertical movements at the surface of the Earth crust were processed to obtain a distribution of velocities in the uniform grid embracing longitudes and latitudes. The processing procedure was carried out on the basis of the Kraiging method. The software was developed in Borland Delphi 7.0 programming environment.
Results. Based on the data on the abnormal gravitation field in isostatic reduction and information on the distribution of velocities of horizontal motions on the surface of the Earth crust, a mathematical model of the stress-strain state of the Lithosphere was constructed. With the help of the obtained mathematical model and software complex, the stress-strain state of the Lithosphere was calculated at various depth using elastic and elastic-viscous models, and maps of equipotential distribution of shear elastic-viscous deformations in the lithosphere at the depth of 10 km were constructed.
Discussion and Conclusion. The presented mathematical model and software allow restoring fields of both elastic and elastic-viscous deformations that is fundamental for quantification of elastic-viscous shear stresses deep in the Earth Lithosphere.

Published: March 2019

Introduction. The aim of the work is to develop a mathematical model of a part based on a parametric model of graphic systems.
Material and Methods.The review of the status of the question of developing a mathematical model of a part based on graphic systems showed the possibility of controlling the geometric shape of a part through the variables of a parameterized drawing. A proposal was made to use design parameterization in the calculation of the parameters of technological processes in computer-aided design systems.
Results. The article establishes links between the design parameters of the part drawing and tabular values of the variables. The revealed relationships between the parameters in the drawing and the variables in the table make it possible to change the geometric shape of the part by changing the values in the variable table, i.e. the drawing is managed through the table. It is proposed to use this system of work with the parametric drawing in computer-aided design systems for calculating the parameters of technological processes.
Discussion and Conclusion. The tasks solved in this article allow making a step in increasing the level of automation of parameter calculations in computer-aided design systems. The implementation of the developed methodology for constructing mathematical models of parts based on graphic systems will increase the overall level of automation of developing geometric drawings of parts. The implementation of this technique in computer-aided design systems allows automating the calculation of parameters (cutting modes, time norms, technological dimensions on transitions, etc.).

Published: March 2019

Introduction. Existing machines for harvesting root crops and onions do not have efficient indicators describing separation of root crops that leads to incompliance with agrotechnical requirements to harvesting root crops. New methods should be found to increase quality of root crop separation, including the qualitative indicators, and to cut losses.
Materials and Methods.The article describes the design of a laboratory unit for determining qualitative indicators of the seed onion heap separation using a rod elevator with the asymmetric passive elliptical shaker and supporting roller. The authors describe the method and results of laboratory studies to determine qualitative indicators of seed onion heap separation at an experimental rod elevator.
Results. The results of the laboratory study of the rod elevator are cited and qualitative indices of seed onion heap separation are defined. The maximum completeness of separation of the seed onion heap is 98 %, when the forward speed of the web of the rod elevator is vel = 1.55–1.68 m/s, the supply of heap of onion-seeding QB = 19.7–27.1 kg/s and the interaxial distance between the passive elliptical shaker and the supporting roller is within the range of S = 0.29–0.42 m.
Discussion and Conclusion. The use of a rod elevator with the asymmetric elliptical shakers and supporting roller allows increasing the completeness of separation of seed onions by 20 % and to cut the bulb damage by 11 %, compared to symmetrical arrangement of the shakers.

The present study aims to determine the levels of the heavy metals manganese (Mn) and zinc (Zn) contained in the fungicide Mancozeb in the eggs and musculature of the rainbow trout (Oncorhynchus mykiss W.) which have grown in an environment, containing a permissible amount of Mancozeb and fed with or without the carotenoid pigment astaxanthin. The study follows the feeding, then the analysis of the level of Mn and Zn in the eggs and musculature of the rainbow trout, treated with and without the pigment astaxanthin and the fungicide Mancozeb. The determination of Mn and Zn concentrations is performed using a modern method for measuring macro- and microelements with an atomic absorption spectrometer, which is characterized by high selectivity, swiftness and sensitivity. Experimental data show accumulation of Mn and Zn, contained in the fungicide Mancozeb even when its concentration in the habitat does not exceed the maximum permissible levels in the normative documents. As a result, the analysis of the eggs and musculature shows the same trend regarding the accumulation of Mn and Zn. In non-fertilized, as well as in fertilized rainbow trout eggs and musculature, the experimental data show a slight increase of Mn and Zn in the presence of only astaxanthin in the added feed and a significant decrease in these metals in the presence of both astaxanthin and Mancozeb. The supplementation of astaxanthin in the diet can significantly reduce the rate of heavy metals accumulation in fish tissues and eggs, but high concentrations of these pollutants in the aquatic environment over a longer period of time would certainly result in metabolic disturbances in the fish body and reduction of their eggs’ hatchability.

“¡Me caso y me voy!”: migraciones transnacionales femeninas desde el Caribe hispánico hacia Italia
Authors: Bossio Blanco Verónica Del Carmen
Published: March 2019

El presente artículo abre un espacio de análisis y reflexión, desde un enfoque de género, sobre la relación que el binomio matrimonio-migración tiene sobre las dinámicas de (re)construcción identitaria y la integración en contexto de destino. Mediante una técnica autoetnográfica, a través de mi perspectiva de mujer afrodescendiente del Caribe hispánico que contrajo matrimonio con un italiano y que migró a Italia, dialogo con la experiencia de otras tres mujeres en condiciones similares a la mía. Los resultados muestran que algunas creencias ideológicas nos unen en el concepto de matrimonio y que el mismo no es un fin para dejar los respectivos países de orígenes. Sin embargo, emerge que todas hemos vivido, con facetas diferentes, la estructura de poder basada en el heteropatriarcado transnacional lo cual, de cierta manera, nos condicionó en la decisión de migrar. Finalmente, la fluidez identitaria se ha enfrentado, de un lado con nuestras raíces africanas, invisibilizadas por cada una de nosotras según etapas y circunstancias distintas; de otra parte, por ser el fruto del mundo colonial que aún mantiene su huella con sus paradigmas de dominio hegemónico-racial. También el fenómeno de la integración en lugar de destino se ve ligado a esta lógica, implicando, en algunos casos, un acercamiento al contexto italiano desde una posición de subordinación, principalmente social, cultural y económica.

Published: March 2019

Molybdenum sulfide in the 1T phase (1T-MoS2) has been extensively studied because of its excellent properties and instability, but few studies have been carried out by first principles. The results of the authors’ in-depth study of the effect of cobalt (Co)–nickel (Ni) on 1T-MoS2 are as follows: in comparing with the standard structure, the standard group is used to judge the law of influence on a preliminary basis. The band structure, density of states and differential charge density of 1T-MoS2 are different from those of the standard group when cobalt–nickel is introduced alone. The difference becomes smaller when the proportion of cobalt and nickel is increased. The changes in energy were further studied by the authors’ group. After studying the change in energy barrier, it was found that the binding of cobalt and nickel on the surface of 1T-MoS2 is an energy absorption process, which causes the reaction barrier to become higher. With the increase in the proportion of cobalt and nickel, the reaction barrier increases significantly. The 1T-MoS2 transition barrier is the highest after co-introducing cobalt–nickel, so it is the most difficult to change, which is helpful in improving stabilization. This result is consistent with the previous preliminary study of the electronic structure.

Published: March 2019

In the past two decades the world experienced an exceptional number of unprecedented extreme weather events, some causing major human suffering and economic damage, such as the March 2012 heat event, which was called “Meteorological March Madness.” From the beginning of space era a correlation of solar ﬂares with pressure changes in atmosphere within 2–3 days or even less was reported. In this study we wanted to test the possible relation of highly warm weather events in North-East America with Solar Energetic Particle (SEP) events. For this reason we compared ground temperatures TM in Madison, Wisconsin, with energetic particle fluxes P measured by the EPAM instrument onboard the ACE spacecraft. In particular, we elaborated case events and the results of a statistical study of the SEP events related with the largest (Dst ≤ −150nT) Coronal Mass Ejection (CME)-induced geomagnetic storms, between with the years 1997–2015. The most striking result of our statistical analysis is a very significant positive correlation between the highest temperature increase. ΔTM and the time duration of the temperature increase ΔTM (r = 0.8, p <0.001) at “winter times” ( r = 0.5, p , 0.01 for the whole sample of 26 SEP examined events). The time response of TM to P was found to be in general short (a few days), but in the case of March 2015, during a gradual P8 increase, a cross-correlation test indicated highest c.c. within 1 day (p < 0.05). The March 2012 “meteorological anomaly” was elaborated in the case of South-East Europe, where, beside a period of strong winds and rainfall (6-13.3.2012), intense precipitation in North-East Greece (Alexandroupoli) were found to be correlated with distinct high energy flux enhancements. A rough theoretical interpretation is discussed for the space—atmospheric extreme weather relationship we found. However, much work should be done to achieve early warning of space weather dependent extreme meteorological events. Such future advances in understanding the relationships between space weather and extreme atmospheric events would improve atmospheric models and help people’s safety, health and life.
Effect of Gamma-Ray Irradiation on the Growth of Au Nano-Particles Embedded in the Germano-Silicate Glass Cladding of the Silica Glass Fiber and its Surface Plasmon Resonance Response
Authors: Ju Seongmin , Han Won-Taek
Published: March 2019

The effect of γ-ray irradiation on surface plasmon resonance (SPR) sensing capability of refractive index (n = 1.418–1.448) of the silica glass optical fiber comprised of germano-silicate glass cladding embedded with Au nano-particles (NPs) was investigated. As the γ-ray irradiation increased from 1 hour to 3 hours with the dose rate of 1,190 Gy/h, the morphology of the Au NPs and the SPR spectrum were found to change. The average diameter of Au NPs increased with the aspect ratio from 1 to 2 and the nano-particles became grown to the clusters. The SPR peak wavelength shifted towards longer wavelength with the increase of total dose of γ-ray irradiation regardless of the corresponding refractive indices. The SPR sensitivities (wavelength/refractive index unit, nm/RIU) also increased from 407 nm/RIU to 3,553 nm/RIU, 1,483 nm/RIU, and 2,335 nm/RIU after the γ-ray irradiation at the total dose of 1,190 Gy, 2,380 Gy, and 3,570 Gy, respectively.

Published: March 2019

The Internet-of-Things (IoT) enables enterprises to obtain profits from data but triggers data protection questions and new types of cyber risk. Cyber risk regulations for the IoT however do not exist. The IoT risk is not included in the cyber security assessment standards, hence, often not visible to cyber security experts. This is concerning, because companies integrating IoT devices and services need to perform a self-assessment of its IoT cyber security posture. The outcome of such self-assessment needs to define a current and target state, prior to creating a transformation roadmap outlining tasks to achieve the stated target state. In this article, a comparative empirical analysis is performed of multiple cyber risk assessment approaches, to define a high-level potential target state for company integrating IoT devices and/or services. Defining a high-level potential target state represent is followed by a high-level transformation roadmap, describing how company can achieve their target state, based on their current state. The transformation roadmap is used to adapt IoT risk impact assessment with a Goal-Oriented Approach and the Internet of Things Micro Mart model.

Age-in-place can reduce the progress of dementia syndrome and improve the quality of life of the sufferers and their families. This work proposes an innovative information home support system to be established at the houses of people suffering from dementia. The main innovation of the system are its transparent character that overcomes the need for training of the sufferer, as well as the exploitation of a well-known technique for dementia, namely music therapy. It addresses the need of people suffering from dementia as well as their familiars to be recognized by them and have better interaction and collaboration. The system offers a ubiquitous recognition system, just by using smart devices like smart-phones or smart-wristbands. When a familiar person is detected in the house, then a sound file is reproduced on smart speakers placed in the house, in order to trigger the memory, based on the principles of music therapy. The system reproduced the appropriate time at 100% of the cases and the benefits of music therapy are evident daily. To the best of the authors' knowledge, this is the first system of its kind ever reported in the literature.

The object of this study is to determine of teachers’ opinions on the impacts of exam for the Transition from Basic Education to Secondary Education TEOG system on their teaching activities in visual arts, technology and design, music and physical education courses that are not covered by the TEOG exam.   This research was conducted as a survey study and the study group was determined by the purpose of sampling strategy, data analysis plan and easy accessibility approach. This research was carried out with 35 teachers who teach visual arts, physical education, technology and design, and music courses in public schools in Ankara. Teachers’ opinions were obtained with a form containing five open-ended questions and demographic and occupational characteristics of the teachers. A descriptive analysis approach was applied to the written opinions of the teachers. As a result of this research according to the opinions of teachers; visual arts, technology and design, music and physical education courses which are not included by the TEOG exams were considered to be insignificant by students, school administrators and parents. In addition, teachers stated that the TEOG system affected their teaching and evaluation activities negatively in the classroom, and the teachers were unable to evaluate their students objectively due to the TEOG system, and students, administrators and parents expected or demanded the teacher to give higher grades. Because of these situations, the relations between the teachers, students, school administrators and parents were affected negatively.

Published: March 2019

Excess molar volumes of five ternary mixtures of 2- methoxy ethanol(1) +butyl acetate(2)+benzene(3), +toluene(3), +chlorobenzene(3), +bromobenzene(3), and +nitrobenzene(3) have been measured at 303.15K. The excess molar volume exhibited positive deviation over the entire range of composition in the systems 2-methoxy ethanol(1)+ butyl acetate(2)+ benzene(3),+toluene(3) and sigmoid behavior in the case of the remaining systems. Flory's statistical theory have been extended to predict the excess molar volumes of the five ternary mixtures at 303.15 k over a wide range of composition . An excellent agreement has been found between the experimental and theoretical excess molar volumes , both in magnitude and sign .

Authors: Journal Baghdad Science
Published: March 2019

The nature and intensity of the association of myasthenia gravis (MG) with distinct human leukocyte antigen (HLA) haplotypes differ between ethnic populations, so this study determined the association of HLA class II antigens with myasthenia gravis (MG) in Iraq.The study included Iraqi patients diagnosed with MG and two control groups the first of 54 insulin dependent diabetes mellitus patients and the second of 237 subjects as a normal control group. The test used was microlymphocytotoxicity test.The work was done in the Teaching Laboratories/Medical City/Baghdad.Results: positive associations were observed (etiological risk factors) as follows:
1. HLA-DR locus showed one positively associated allele when compared to healthy control and this was HLA-DR3 (RR: 21.05, EF0.73, & P value ? 0.05), While when compared to IDDM control no significant association appeared (since the same allele is positively associated with IDDM).
2. HLA-DQ locus showed only one positively associated allele when compared to healthy control; this was HLA-DQ2 (RR 4.67, EF 0.50, and P value ? 0.05). While no significant association appeared when compared to IDDM control.
Other important clinical association were observed; association with age, gender, strong stressful events, thymoma, and other autoimmune disorders.
Conclusion: The positively associated antigens which were found as follows HLA-DR3 and HLA-DQ2, while no negative association was detected.
