In order to measure working mental health along with the components of psychological health, it can be used the questionnaire with Iranian samples

Effects Of Column Splice Properties On Seismic Demands In Steel Moment Frames

Dynamic inelastic response history analysis of a 2-D model of a nine storey steel frame were carried out with different column splice strengths and stiffnesses using a suite of 20 MCE level earthquake records. Splices were located every 2nd storey at one third of the storey height up from the column below. It was shown that (i) the presence of even very flexible splices increased the frame period by less than 3%, (ii) flexible splices increased storey drift ratios by up to 27%, (iii) splice stiffnesses of zero to infinity had no effect on frame displacements, (iv) the splice moment demand increased with increasing splice stiffness on the frame and was as high as 99% of the column flexural capacity

Assessment of care offered to the healthy newborn in the natural normal vaginal delivery and the cesarean section

Background and aims: Care services to infants in the length of primary time after birth has much effect on the health and decrease of their mortality and morbidity. This study aimed to assess the care provided to the healthy newborn in the normal vaginal delivery (NVD) and the cesarean section (CS) in the hospitals affiliated with Shahrekord University of Medical Sciences. Methods: This descriptive study has been performed upon 282 healthy term infants (104 CS and 178 NVD cases) through direct observation and using the health care evaluation checklists. Data were analyzed using , SPSS software and t-test and Mann- Whitney tests. Results: The average of total health infant services among all of the samples was 58/3% and the percentage of agreement with standard of healthy infants care was more in NVD than CS labor (P=0.011). The emergency acts to retrieve and supporting services to feed infants with mothers’ milk in the CS group were more than NVD infants, but these infants received poor care in the area of primary procedures and assessment, and procedures to contact to mothers and infant. Also, the length of skin contact time between infants and their mothers after delivery and initiating to feed infants with mothers’ milk in the primary time in the CS group was lower than NVD infants(P=0.000). Conclusion: Assessment of care services to healthy infants in hospitals under study had average quality and its quality was even lower in CS labors than NVD labors. Therefore, it can be performed more procedures to promote quality of care services to infants by health approaches in mothers education to develop NVD and reduce active CS

Cohesive-frictional model for bond and splitting action of prestressing wire

This paper presents a numerical procedure for bond between indented wires and concrete, and the coupled splitting process of the surrounding concrete. The bond model is an interface, non-associative, plasticity model. It is coupled with a cohesive fracture model for concrete to take into account the splitting of such concrete. Bond between steel and concrete is fundamental for the transmission of stresses between both materials in precast prestressed concrete. Indented wires are used to improve the bond in these structural elements. The radial component of the prestressing force, increased by Poisson's effect, may split the surrounding concrete, decreasing the wire confinement and diminishing the bonding. The combined action of the bond and the splitting is studied with the proposed model. The results of the numerical model are compared with the results of a series of tests, such as those which showed splitting induced by the bond between wire and concrete. Tests with different steel indentation depths were performed. The numerical procedure accurately reproduces the experimental records and improves knowledge of this complex proces

Spiropyran-based reversible, light-modulated sensing with reduced photofatigue

Switchable materials have tremendous potential for application in sensor development that could be applied to many fields. We are focusing on emerging area of wireless sensor networks due to the potential impact of this concept in society. Spiropyran-based sensors are probably the most studied type of photoswitchable sensing devices. They suffer from many issues but photofatigue, insufficient selectivity and lack of sensitivity are probably the most important characteristics that hinder their wider application. Here, we are address these issues and demonstrate that covalent attachment of modified spiropyran into a polymeric film significantly reduces photodegradation. The observed signal loss after 12th cycle of switching between the spiropyran and merocyanine forms is only about 27% compared to the loss of 57% of the initial signal in an equivalent experiment based on non-immobilized spiropyran. This has enabled us to demonstrate at least five reversible cycles of detection of an ion of interest (in our case H+) with minimal signal loss. Furthermore, we demonstrate that the sensitivity can be increased by incorporation of additional binding groups in the parent spiropyran molecule. Using molecular modelling to calculate the relevant bond lengths as a measure of interaction between MC and H+, the calculated increase of H-bond strength is approximately an order of magnitude for a derivative containing a methoxy group incorporated in the o-position of the parent spiropyran in comparison to the equivalent unsubstituted phenol. This theoretical result was found to correspond very well with experimental observation. As a result, we have increased the sensitivity to H+ by approximately one order of magnitude

Methods for complex treatment of children with obstetric paralysis

During childbirth in case of incorrect birth management, pelvio-fetal disproportion, breech or leg presentation, etc. it is possible to damage the Plexus brachialis. Peripheral nerve damage most often occurs during manual fetal retrieval. The trauma leads to compression, stretching or rupture of the brachial /shoulder/ plexus with the resulting consequences: flaccid paresis or paralysis of the muscles of the upper limb of the child with involvement of the peripheral nerves.For several days after birth, the whole arm is paralyzed and difficult to move. Recovery depends on the severity of the damage. With proper and timely treatment, the chance of a full recovery is huge.Our study aims to establish the importance of massage as part of a comprehensive outpatient treatment of children with obstetric paralysis.We used a documentary method, analyzing literature sources examining the subject of the present study and monitoring in a rehabilitation center, where complex treatment was applied. Timely diagnosis and immediate care and rehabilitation, including massage and/ or passive and active kinesitherapy, lead to the appearance of active movements.In order to build the most correct behavior towards the sick child, the parents need to be acquainted with the nature of the disease, the home regime, the nutrition, etc. Conservative therapy and rehabilitation up to the 3rd year are effective, in more severe cases at this age a surgical intervention is most appropriate (2). From the present study we can draw the following conclusions: 1. Massage plays a leading role, especially at an early age. 2. Kinesitherapy is the most important and is the basis of treatment. 3. The parents contribute greatly to the healing process

Computational Perspective on Intricacies of Interactions, Enzyme Dynamics and Solvent Effects in the Catalytic Action of Cyclophilin A

Cyclophilin A (CypA) is the well-studied member of a group of ubiquitous and evolutionarily conserved families of enzymes called peptidyl–prolyl isomerases (PPIases). These enzymes catalyze the cis-trans isomerization of peptidyl-prolyl bond in many proteins. The distinctive functional path triggered by each isomeric state of peptidyl-prolyl bond renders PPIase-catalyzed isomerization a molecular switching mechanism to be used on physiological demand. PPIase activity has been implicated in protein folding, signal transduction, and ion channel gating as well as pathological condition such as cancer, Alzheimer’s, and microbial infections. The more than five order of magnitude speed-up in the rate of peptidyl–prolyl cis–trans isomerization by CypA has been the target of intense research. Normal and accelerated molecular dynamic simulations were carried out to understand the catalytic mechanism of CypA in atomistic details. The results reaffirm transition state stabilization as the main factor in the astonishing enhancement in isomerization rate by enzyme. The ensuing intramolecular polarization, as a result of the loss of pseudo double bond character of the peptide bond at the transition state, was shown to contribute only about −1.0 kcal/mol to stabilizing the transition state. This relatively small contribution demonstrates that routinely used fixed charge classical force fields can reasonably describe these types of biological systems. The computational studies also revealed that the undemanding exchange of the free substrate between β- and α-helical regions is lost in the active site of the enzyme, where it is mainly in the β-region. The resultant relative change in conformational entropy favorably contributes to the free energy of stabilizing the transition state by CypA. The isomerization kinetics is strongly coupled to the enzyme motions while the chemical step and enzyme–substrate dynamics are in turn buckled to solvent fluctuations. The chemical step in the active site of the enzyme is therefore not separated from the fluctuations in the solvent. Of special interest is the nature of catalysis in a more realistic crowded environment, for example, the cell. Enzyme motions in such complicated medium are subjected to different viscosities and hydrodynamic properties, which could have implications for allosteric regulation and function

Viral Quasispecies Reconstruction Using Next Generation Sequencing Reads

The genomic diversity of viral quasispecies is a subject of great interest, especially for chronic infections. Characterization of viral diversity can be addressed by high-throughput sequencing technology (454 Life Sciences, Illumina, SOLiD, Ion Torrent, etc.). Standard assembly software was originally designed for single genome assembly and cannot be used to assemble and estimate the frequency of closely related quasispecies sequences. This work focuses on parsimonious and maximum likelihood models for assembling viral quasispecies and estimating their frequencies from 454 sequencing data. Our methods have been applied to several RNA viruses (HCV, IBV) as well as DNA viruses (HBV), genotyped using 454 Life Sciences amplicon and shotgun methods

The Social Semiotic Analysis of Translation of Joseph Conrad’s Heart of Darkness Based on Peircean Model

The aim of the present article is to investigate the meaning of the signs in Persian translation of Heart of Darkness. To reach the desired goal, the researcher has used social semiotics and Peirce’s triadic sign model as the theoretical framework. In the current study, Peirce semiotics has been used for detecting signs. After detection 50 signs, the researcher used Peirce’s triadic sign model for analyzing the translation of each sign. The researcher decoded the signs to identify their components and analyzed them in social semiotic level to clarify whether they have the same impression on the Persian version of Heart of Darkness as their English source or not. After performing data analysis, it was cleared that 37 signs (out of 50) in the corpus of the study have the same effect and meaning in the target text as what they have in the source text

Grace in Marilynne Robinson's Gilead and Georges Bernanos's The diary of a Country Priest

Marilynne Robinson's Gilead (2007), a meditative letter written by an aging minister, probes the need for forgiveness and grace. George Bernanos's The Diary of a Country Priest (1936) pictures the suffering and sacrifice of an unnamed young priest in his attempt to open his parishioner’s heart to the love of God. Both novelists explore themes such as forgiveness, love, peace, faith, and grace. This paper first discusses the prevalent Christian themes in these novels, and the ways each novelist presents the saving and life-giving power of God's grace in healing and restoring human soul, and then compares their treatment of these issues. The Protestant Robinson's sensibility regarding these religious themes seems very similar to that of the Catholic Bernanos. Indeed, the American writer seems to be considerably influenced by her French predecessor
