Developing particle-based models to predict solar energy attenuation using long-term daily remote and local measurements
No full textIran has an annual average of 2.8–5.4 kW h/m2d of radiation and has a high capacity for extracting electricity from its solar resources. Tehran, the capital of Iran, is one of the most polluted cities in the world in terms of atmospheric aerosols. Due to the rising air pollution in Tehran, the existing research is outdated. An analysis of the loss of electricity generation due to particulates can significantly affect the feasibility of a photovoltaic power plant in Tehran. Several factors affect the electricity generation of photovoltaic systems. The most critical is solar radiation. The amount of solar radiation transmitted and, ultimately, the amount of electricity generated depends on several atmospheric factors. One of the most important factors is the concentration of suspended particles of different sizes. In the present work, linear models based on observed suspended particle concentrations, including PM10 and PM2.5, have been proposed for Tehran from 2014 to 2020 to anticipate the aerosol attenuation index due to aerosols. Based on the correlation coefficient values (R), in the first and last months of the year, November, December, and January, the models performed better to predict the aerosol attenuation index based on PM2.5. The R values were, in order, 0.1553, 0.2926, and 0.1341. As remote measurements, the NASA CERES syn 1-deg product parameters and, as ground observations, Surface Solar Radiation (SSR) and PM10 and PM2.5 concentrations were used to estimate the impacts of aerosols on radiation. With the help of the CERES syn 1-deg product, it is declared that, on average, 8.30% of the total radiation received was wasted due to the presence of aerosols. Considering observed SSR, CERES syn 1-deg product performance was validated, with RMSE and MBD values of 14.09% and 10.89%, respectively
Evaluating the Bifidogenic Effect of Various Infant Formula Supplementations: A Systematic Review and Network Meta-Analysis of Randomised Controlled Trials
No full textThis study aimed to investigate the effects of infant formula supplements on Bifidobacterium level in the infant gut through a systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs).
Systematic review included PubMed, EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL to identify RCTs evaluating the effects of formulas supplemented with prebiotics, probiotics, synbiotics, β-palmitic acid, or combinations of β-palmitic acid with prebiotics on infant gut Bifidobacterium levels. A meta-analysis compared bifidogenic effects to standard formula. The main outcome was the relative abundance (RA) of Bifidobacterium in fecal samples measured by various microbiota assessment techniques, with effect sizes as mean differences and standard deviations. An overall effect estimate was derived using a random-effects model. NMA assessed formula effects using breastfeeding as the reference.
Nineteen studies were included. Compared to standard formula, supplementation with prebiotics (p < 0.0001), synbiotics (p < 0.0001), β-palmitic acid (p = 0.0005), or β-palmitic acid combined with prebiotics (p < 0.0001) significantly increased Bifidobacterium levels in the infant gut. Probiotic supplementation showed no significant effect (p = 0.9755). NMA and p-score ranking, comparing formulas to breastmilk, indicated that prebiotic-supplemented formulas with the lowest ranking p-score (0.2764), most closely resembled breastfeeding’s bifidogenic effect. However, prebiotics and probiotics were analyzed as broad categories, and group variability may affect outcomes. In conclusion, formula supplementation with prebiotics, synbiotics, β-palmitic acid, or combinations of β-palmitic acid with prebiotics increased the RA of Bifidobacterium in infant’s gut, with prebiotic formula most closely mimicking the bifidogenic effects of breastfeeding

THE ROLE OF NA(2)O(EQ )RATIO ON THE FLOWABILITY AND STRENGTH DEVELOPMENT OF CEMENTITIOUS SYSTEMS IN THE PRESENCE OF A POLYCARBOXYLATE ETHER-BASED ADMIXTURE
No full textIn this study, the effect of equivalent Na2O(Na2Oeq) ratio of cement on fresh properties and compressive strength of paste and mortar mixtures containing polycarboxylate ether-based high range water reducing (HRWR) admixture was investigated. A low and a high alkali cement were used. Five mixtures having five different Na2Oeq ratios were prepared with increasing alkali content of the cement by incorporating three different amounts of NaOH solution to the low alkali cement-bearing mixtures. Irrespective of the absence or presence of HRWR, Na2Oeq content of the mixtures was found to have a considerable adverse effect on the fresh properties of the mixtures, particularly on their flow loss. NaOH addition increased 1-day compressive strength of the mortar mixtures, however, reduced the compressive strength at later ages. In spite of having a lower fineness and a longer setting time, low alkali cement showed slightly higher 1-day strength than high alkali cement. This seems to have occurred, to some extent, from the higher HRWR admixture demand (0.4 wt.%) of the high alkali cement-bearing mixture than that of the mix containing low alkali cement (0.25 wt.%). At later ages, both of the cements showed equivalent strength values.Turkish Cement Manufacturers AssociationThe authors would like to thank Baticim and Oyak cement plants for their kind assistance in providing the cements and determining the chemical composition of the cements. The first author would like to acknowledge the scholarship provided by Turkish Cement Manufacturers Association during his PhD study
Psychosocial Distress as a Factor in Patients With Cancer Seeking Support: A Hermeneutic Study
No full textCancer is one of the main causes of human death in the world, but its mortality rates have been in continual decline for the past 20 years (Siegel, Miller, & Jemal, 2015). It is a growing problem in Middle Eastern countries (Daher, 2011). In Iran, an ancient country in the Middle East (Borimnejad, Mardani-Hamooleh, Seyedfatemi, & Tahmasebi, 2014), cancer is the third most common cause of death, after heart disease and traffic accidents. The incidence of cancer in Iran is anticipated to be around 48 to 112 and 51 to 144 cases per year per million people for women and men, respectively (Seyedfatemi, Borimnejad, Mardani-Hamooleh, & Tahmasebi, 2014).
As the incidence of new cases of cancer increases every year, breaking bad news to patients is very important. Bad news is described as any piece of information that could potentially be directed to negatively change a patient’s expectations, ideas, feelings, or outlook (Salem & Salem, 2013). Breaking bad news to patients with cancer is a delicate and challenging task for most health-care providers (Eng, Yaakup, Shah, Jaffar, & Omar, 2012). Bad news about cancer creates pain for patients (Zebrack, Chesler, & Kaplan, 2010). It is unexpected and often may come as a shock (Yoo, Levine, Aviv, Ewing, & Au, 2010). In this regard, despite efforts by family members to conceal cancer diagnoses from patients, the majority of patients discovered the diagnosis of their own accord (Wang, Guo, Peng, Su, & Chen, 2011).
Breaking bad news to patients with cancer is diverse across different cultures (Table 1). Nondisclosure is the norm for Iranian people. However, health-care workers often want to tell patients of their diagnosis but worry that breaking bad news could evoke fear and anxiety for patients. In fact, it is difficult for health-care workers to predict cancer patients’ responses following disclosure. Therefore, a significant percent of cancer patients in many Mediterranean countries, such as Iran, are not made aware of their diagnosis, and many health-care workers prefer to disclose the cancer diagnosis directly to patients’ family members. However, the clinical experiences of the researchers show that family members rarely transfer this information to patients, and frequently prevent the disclosure of the cancer diagnosis

Correlation of serum adiponectin level with some biochemical and metabolic factors in stable hemodialysis patients
No full textIntroduction: Serum adiponectin is a hormone secreted by the adipose tissue and its level usually increases in patients
with renal insufficiency. In uremic condition, it not only loses its protective role against atherosclerosis, but also
becomes a risk factor. This hormone is a direct predictor of cardiovascular complications in patients with renal failure.
Objectives: This study was designed to assess the association between serum adiponectin with various parameters in
in a group of non-diabetic hemodialysis patients.
Patients and Methods: In this study, 73 hemodialysis non-diabetic patients were selected and fasting blood samples were
taken to measure adiponectin and some other biochemical parameters. Waist circumference, abdominal circumference,
weight and body mass index (BMI) were measured. Pearson statistical test was used to find the association between
adiponectin and mentioned parameters.
Results: Adiponectin level was negatively and significantly associated with weight (P<0.001), BMI (P<0.001), waist
circumference (P<0.05), abdominal circumference (P<0.01), and triglycerides (P<0.01).
Conclusion: According to the results of our study, serum adiponectin level in hemodialysis patients was negatively
associated with weight and BMI which indicates the likely effect of the hormone. As a result, finding of exact
connections between this cytokines and the risk factors of atherosclerosis and hypercatabolism may help to introduce
serum adiponectin as a measurable and important marker for atherosclerosis and may be used as an index for prognosis
of mortality in this type of patients.

No full textAbstract
Introduction: Pulmonary artery hypertension in end-stage renal disease is associated by significantly increased
morbidity and mortality. Serum parathormone may increase among patients on hemodialysis and influence various
organs.
Objectives: This study sought to find the association of serum parathormone level and pulmonary artery pressure in a
group of non-diabetic patients on regular hemodialysis.
Materials and Methods: This prospective investigation was conducted in the hemodialysis section of Shahrekord
University of Medical Sciences in 2013. Doppler echocardiography were used to assess pulmonary artery pressure.
Pulmonary arterial hypertension is defined as systolic PAP≥35 mm Hg at rest. Serum parathormone was measured by
ECL method.
Results: Sixty-five, non-diabetic hemodialysis patients were studied. Mean (±SD) of age of the patients was 56.35±20.41
years. Mean (±SD) of iPTH was 251.55±97.27 pg/ml. In this study, a significant positive association of serum iPTH with
pulmonary artery pressure in patients was seen (r=0.27, p=0.029).
Conclusion: In the present study, we detected a significant positive association of serum parathyroid hormone with
pulmonary artery pressure of hemodialysis patients however, our observations, warranting further investigations to
evaluate the clinical aspect of the association of serum PTH with pulmonary artery pressure.
