Antimicrobial effects of chlorhexidine, matrica drop mouthwash (chamomile extract), and normal saline on hospitalized patients with endotracheal tubes
Background: The functions and use of mouthwashes are variable depending on their type. Oral care in patients with endotracheal tubes is important to prevent side effects such as pneumonia. The aim of this study was to determine the antimicrobial effects of chlorhexidine, drop of Matrica mouthwash (chamomile extract), and normal saline on hospitalized patients with endotracheal tube in an intensive care unit (ICU). Materials and Methods: In this clinical trial, 39 patients admitted to the ICU were selected by convenience sampling, were matched based on age and sex, and randomly assigned to three groups (chlorhexidine, Matrica, saline). Mouth washing was performed every 8 to 48 hours. The samples were taken at time zero (before the intervention) and 48 hours after the intervention for bacterial culture. Antibacterial activity of each mouthwash on microorganisms was measured based on the growth of Staphylococcus aureus, Pneumococcal, Enterococcus, Pseudomonas, and Escherichia coli. The obtained data were then analyzed using Chi-square and Fisher's exact tests with the Statistical Package for the Social Sciences Package version 18. Results: Chlorhexidine mouthwash was more effective in preventing colonization of bacteria in the mouth (point probability = 0.06) in comparison with chamomile and saline mouthwashes. Nevertheless, none of the tested mouthwashes were able to remove pathogens, including Staphylococcus aureus, Pseudomonas, Klebsiella, and Acinetobacter. Conclusions: 0.2% chlorhexidine mouthwash has a significant effect on the bacterial colonization rate in comparison with Matrica and normal saline mouthwashes in ICU hospitalized patients with endotracheal tube
Seroprevalence of toxocariasis in children aged 1-9 years in western Islamic Republic of Iran, 2003
We determined the seroprevalence of Toxocara canis infection in 544 children under 10 years randomly selected from urban and rural areas of Hamadan, An enzyme-linked immunosorbent assay was used for detection of antibodies to T. canis excretion - secretion antigens. Using a questionnaire, epidemiological factors associated with infection were examined, including age, sex, residence. Antibodies to T. canis were detected in 29 children (5.3%) and 19 children (3.5%) were categorized as borderline positive; thus together this gave a prevalence of toxocariasis of 8.8%. No significant differences were found in terms of sex, age and residence

Introduction: Violence against women is a universal phenomenon which has negative impact on the mental health of the family and society, and the consequences such as increased health care costs, reduced productivity and labor force of women are another results of this health and social cultural problem. So, this study was performed with aim to determine types of domestic violence and its related factors in pregnant women.
Methods: This descriptive-analytic study was performed on 368 pregnant mothers in area of Kalaleh in 2014. Data were collected by simple sampling and using a questionnaire. Data was analyzed with SPSS software (version 19) and descriptive statistics and Fisher's exact test, Chi-square, independent t-test, and Pearson correlation test.
Results: 312 pregnant women (84.78%) had been exposed to different types of violence. The most common type of violence against pregnant women was emotional with 181 cases (49.18%) and 78 (21.20%) complained of physical violence and 53 (14.40%) of sexual violence. Increased education reduced violence against women. There was a significant relationship between domestic violence, smoking and lack of husband's employment (P <0.05).
Conclusion: According to high rate of domestic violence, it is recommended to screen violence in the all health and therapy centers. Also, life skills training and counseling culture among couples is important
Effect of replacement of Caspian Sea gammarus meal by partial kilka fish meal on growth performance, feed conversion ratio and survival of juveniles of rainbow trout (Oncorhynchus mykiss)
The effects of using different of gammarus meal levels (0, 5, 10 and 20%) instead of kilk fish meal as a protein source on growth performance, feed conversion ratio and survival of rainbow trout (Oncorhynchus mykiss) fingerlings were studied over 8 weeks. Rainbow trout fingerlings (mean body weight 5.48 ± 0.32g) were reared in a completely randomized design with three replications in the same conditions. Based on the results, no significant difference was observed in the final length and weight and specific growth rate among treatments. Increase of gammarus meal in diet led to increase of feed conversion ratio and decrease of survival, but the difference was not significant among treatments. Commercial analysis showed that the cost price of feed increased with increase of gammarus meal in diet, significantly. Thus, results of our study showed that adding up to 10% of gammarus meal instead of kilka fish meal in rainbow trout fingerlings diet is suitable, considering gammarus abundance in the shores of south Caspian Sea and lack of significance in difference on growth, feed conversion ratio and survival

Correlations and the Cross Section of Exclusive () Reactions for O
The reduced cross section for exclusive () reactions has been studied
in DWIA for the example of the nucleus O using a spectral function
containing effects of correlations. The spectral function is evaluated directly
for the finite nucleus starting from a realistic nucleon-nucleon interaction
within the framework of the Green's function approach. The emphasis is focused
on the correlations induced by excitation modes at low energies described
within a model-space of shell-model configurations including states up to the
 shell. Cross sections for the -wave quasi-hole transitions at low
missing energies are presented and compared with the most recent experimental
data. In the case of the so-called perpendicular kinematics the reduced cross
section derived in DWIA shows an enhancement at high missing momenta as
compared to the PWIA result. Furthermore the cross sections for the - and
-wave quasi-hole transitions are presented and compared to available data at
low missing momenta. Also in these cases, which cannot be described in a model
without correlations, a good agreement with the experiment is obtained.Comment: 12 pages, LaTeX, 4 figures include
Enhancing properties of iron and manganese ores as oxygen carriers for chemical looping processes by dry impregnation
The use of naturally occurring ores as oxygen carriers in CLC processes is attractive because of their relative abundance and low cost. Unfortunately, they typically exhibit lower reactivity and lack the mechanical robustness required, when compared to synthetically produced carriers. Impregnation is a suitable method for enhancing both the reactivity and durability of natural ores when used as oxygen carriers for CLC systems. This investigation uses impregnation to improve the chemical and mechanical properties of a Brazilian manganese ore and a Canadian iron ore. The manganese ore was impregnated with Fe2O3 and the iron ore was impregnated with Mn2O3 with the goal of forming a combined Fe/Mn oxygen carrier. The impregnated ore’s physical characteristics were assessed by SEM, BET and XRD analysis. Measurements of the attrition resistance and crushing strength were used to investigate the mechanical robustness of the oxygen carriers. The impregnated ore’s mechanical and physical properties were clearly enhanced by the impregnation method, with boosts in crushing strength of 11–26% and attrition resistance of 37–31% for the impregnated iron and manganese ores, respectively. Both the unmodified and impregnated ore’s reactivity, for the conversion of gaseous fuel (CH4 and syngas) and gaseous oxygen release (CLOU potential) were investigated using a bench-scale quartz fluidised-bed reactor. The impregnated iron ore exhibited a greater degree of syngas conversion compared to the other samples examined. Iron ore based oxygen carrier’s syngas conversion increases with the number of oxidation and reduction cycles performed. The impregnated iron ore exhibited gaseous oxygen release over extended periods in an inert atmosphere and remained at a constant 0.2% O2 concentration by volume at the end of this inert period. This oxygen release would help ensure the efficient use of solid fuels. The impregnated iron ore’s reactivity for CH4 conversion was similar to the reactivity of its unmodified counterpart. The unmodified manganese ore converted CH4 to the greatest extent of all the samples tested here, while the impregnated manganese ore exhibited a decrease in reactivity with respect to syngas and CH4 conversion.EPSR
Generating GHZ state in 2m-qubit spin network
We consider a pure 2m-qubit initial state to evolve under a particular
quantum me- chanical spin Hamiltonian, which can be written in terms of the
adjacency matrix of the Johnson network J(2m;m). Then, by using some techniques
such as spectral dis- tribution and stratification associated with the graphs,
employed in [1, 2], a maximally entangled GHZ state is generated between the
antipodes of the network. In fact, an explicit formula is given for the
suitable coupling strengths of the hamiltonian, so that a maximally entangled
state can be generated between antipodes of the network. By using some known
multipartite entanglement measures, the amount of the entanglement of the final
evolved state is calculated, and finally two examples of four qubit and six
qubit states are considered in details.Comment: 22 page
Provision of Mentorship Services for Midwives Working in Remote Areas in the Workplaces of Afghanistan
Background
Midwives working in remote facilities have little opportunity to receive technical support and coaching services. To close this gap and support rural midwives the Afghan Midwives Association (AMA) designed a field-based mentorship program for midwives working in remote areas.
Methods
The process included five stages:   Conduct base line assessment of mentees (midwives) and health facilities. Identify and select of mentees through competitive process. Provide on-the-job coaching and mentoring services to the mentees. Assess the progress of the midwives regularly using existing quality assurance performance standards. End-line / final evaluation 
Results:
That results of assessments were encouraging antenatal care (ANC), rising from an average of 20% at the baseline to 88% in the final assessment round. Comparable improvements were found for normal labor, childbirth, and immediate newborn care (19% to 85%), postnatal care (16% to 85%), management of antenatal, intra-partum and postpartum complications (15% to 94%), and support systems (38% to 81%)
Factors influencing project delay : a case study of the Vale Malaysia Minerals Project (VMMP)
Delays are one of the biggest problems faced by the construction industry. The delays in construction projects have significant financial and social impact to parties involved in the projects. The main objective of this study is to explore the causes of delay in the Vale Malaysia Minerals Project (VMMP) in Lumut, Perak. This study was conducted by using a qualitative approach. A series of  face to face interviews were conducted with an expert from construction organization and  VMMP staff.  Responses were analysed qualitatively using content analysis  and a comprehensive interpretation was developed. The results revealed that several factors that contribute to the delay in VMMP completion, i.e. communication, delayed in material delivery, and poor management on site, etc. Time and cost overrun were the common effects of delays in construction project. The findings of this study will help the project manager or the client to take necessary measures and to use of supply chain management  to avoid delays of project completion in a construction project
