Motor Responses and Weight Gaining in Neonates through Use of Two Methods of Earmuff and Receiving Silence in NICU
Background and Aims. With technological advances in NICUs the survival rate of preterm infants has been increased. Because NICU environment is a potent source of stress for infants, its modification is an essential measure to decrease infants’ morbidity. The purposes of this study were to compare the effects of wearing earmuff and provision silence for infants on their motor responses and gaining weight. Methods. In a randomized clinical trial 96 preterm infants were enrolled. Their motor responses were evaluated for two consecutive days in the morning and afternoon shifts, in the groups of earmuff and silence, and at similar time points in the control group. Also their weight was measured at days 1 and 10. Results. In the two intervention groups, means of motor responses in infants were significantly less than in the control group, and weight gain of infants was more than the control group. However weight gain was more pronounced in the earmuff group. Conclusion. Both interventions led to decreasing number of motor responses and improvement of weight gain pattern, but these effects were more pronounced in earmuff group; thus because implementation of silence in NICUs has many barriers, it is suggested to use earmuff for preterm infants in these units. This trial obtained IRCT registration number IRCT2012092010812N2

Rancang Bangun Sistem Klasifikasi Frekuensi Penggunaan Minyak Goreng Dengan Menggunakan Metode Bayes
Penggunaan minyak goreng secara berulang melebihi batas wajar dapat menimbulkan berbagai macam penyakit yang sangat berbahaya bagi kesehatan manusia, seperti gagal jantung, berisiko tinggi terkena penyakit diabetes, jantung koroner, dan lain-lain. Namun, saat ini penggunaan minyak goreng secara berulang masih tinggi. Hal itu ditunjukkan oleh hasil penelitian di Kota Maskassar menunjukkan masyarakat miskin dan tidak miskin menggunakan minyak goreng yang sama untuk menggoreng dua kali sebanyak 61,2 persen, tiga kali sebanyak 19,6 persen, dan empat kali sebanyak 5,4 persen. Dari permasalahan tersebut, maka diperlukan sistem otomatisasi untuk mengklasifikasi frekuensi penggunaan minyak goreng sehingga dapat digunakan untuk klasifikasi frekuensi penggunaan minyak goreng yang telah digunakan beberapa kali secara akurat. Pada penelitian kali ini, parameter yang digunakan adalah warna dan tingkat kekeruhan minyak goreng. Penentuan klasifikasi minyak goreng berdasarkan warna dan tingkat kekeruhan minyak goreng diperoleh dari hasil pembacaan sensor warna TCS3200 dan sensor fotodioda oleh mikrokontroler Arduino uno dengan menggunakan metode Bayes, karena metode ini merupakan salah satu metode klasifikasi yang cukup sederhana, mudah dipahami, dan memunyai kecepatan komputasi yang tinggi. Dari hasil pengujian yang dilakukan, diketahui persentase error pembacaan sensor warna TCS3200 adalah sebesar 1,9% dan sensor fotodioda dapat bekerja dengan baik. Terlihat apabila minyak goreng keadaannya semakin keruh, maka nilai dari sensor fotodioda semakin kecil. Selanjutnya, pada pengujian sistem menggunakan metode Bayes dengan jumlah data latih sebanyak 65 data dan data uji sebanyak 35 data, diperoleh akurasi sebesar 71,42% dengan waktu komputasi sistem rata-rata selama 13,144 detik
Studyof Wastewater and Compost Effects on Some of Soil Physical and Chemical Characteristics
Introduction: Arid and semi-arid areas are confronting increasing water shortages. In these regions of the world, planners are being forced to consider other water sources that could be used economically and effectively to promote further development. Wastewater is the only potential water source, which will increase as the population grows and the demand on freshwater increases. Composting municipal solid wastes (MSW) and sewage sludge is a good way to reduce the amount of wastes generated in densely populated areas. Municipal solid waste production in Asia in 1998 was 0.76 million tons per day, with an annual growth rate of 2- 3% in developing countries and 3.2- 4.5% in developed countries. (MSW) compost is increasingly used in agriculture not only as a soil conditioner but also as a fertilizer. Despite the growing interest in wastewater and compost usage, excessive application of them may have some harmful effects such as human health problems, runoff and leaching of nutrients to surface and groundwater, undesirable chemical constituents, pathogens, accumulations of heavy metals in plants and soils, negative environmental and health impacts. So, using of wastewater and compost application should be under controlled conditions that minimize health risks of agricultural products.
Materials and Methods: This study was conducted in greenhouse of Bu-Ali Sina as a factorial completely randomized design to evaluate the effects of wastewater and compost on physical and chemical properties of soil. The factors included four types of watering: raw wastewater (W1), treated wastewater (W2) combined 50% of raw wastewater and fresh water (W3) and tap water (W4) and also four compost levels: 0 (C1), 40 (C2), 80 (C3) and 120 tha-1 (C4). Therefore, 16 treatments (W1C1 to W4C4) were considered for investigation. It is noted that Compost added and mixed just with top layer of the soil. 48 volumetric lysimeters were applied as Cultivation beds (26 × 30 × 30 cm). The soil had three layers: the upper layer (Clay texture), the middle layer (clay loam) and the bottom layer (sandy clay loam). After beds preparation, basil (Ocimum Basilicum) was planted in them. Due to the lack of an active wastewater treatment plant in the region, raw and treated wastewaters were transported from Kermanshah, the nearest city to Hamedan. Also, municipal compost was prepared from Kermanshah Compost Company.At the end of cultivation period, the soil samples (from 0-15 cm) were collected and the amount of physical (hydraulic conductivity, bulk and particle density and porosity)and chemical (nitrogen, phosphorus and potassium) properties were measured.
Results and Discussion: The results showed that the water quality has a significant effect on all parameters and the amount of compost has significant effect on all parameters except bulk density. But, the amount of all parameters (except hydraulic conductivity) was not influenced by interaction between water quality and compost levels. In all treatments, the range of hydraulic conductivity, bulk density, particle density and total porosity were varied between 23.82 to 35.61 mmh-1, 1.41 to 1.43 grcm-3, 2.51 to 2.57 grcm-3 and 42.88 to 45.19 %, respectively. Also the range of nitrogen, phosphorus, and potassium were varied between 0.06 to0.08 %, 14.64 to232.28mgkg-1,and 393.22 to519.84mgkg-1,respectively.Overall, the results indicated that using compost and wastewater increased hydraulic conductivity, porosity, nitrogen, phosphorus, and potassium of the soil in comparison to the control. Whereasbulk and particle density of soil decresed by using compost and wastewater (as a mixed material).
Conclusion: In this study, we investigated the effect of wastewater and compost on some of soil physical properties (hydraulic conductivity, bulk density, particle density and total porosity) and also some of chemical properties of soil nitrogen, phosphorus and potassium).The results showed that the use of wastewater and compost on soil physical condition has a positive effect.Wastewater and compost by improving the soil pore size distribution, decreased the bulk and particle density and increased porosity and hydraulic conductivity of the soil. The impact of wastewater and compost to improve the physical properties, commensurate with the level of wastewater treatment and composting rate in the soil. Also using the wastewater (raw wastewater, treated wastewater and combined 50% of raw wastewater and fresh water) and compost (40, 80 and 120 tha-1), compared to the control (fresh water and soil without compost), increased total of nitrogen, phosphorus and potassium of soil. But, due to the risks of soil salinity and nitrogen leaching, it is suggested that longterm exposure to wastewater and compost needs a careful practical management
THERMAL AND VISIBLE SATELLITE IMAGE FUSION USING WAVELET IN REMOTE SENSING AND SATELLITE IMAGE PROCESSING
Multimodal remote sensing approach is based on merging different data in different portions of electromagnetic radiation that improves the accuracy in satellite image processing and interpretations. Remote Sensing Visible and thermal infrared bands independently contain valuable spatial and spectral information. Visible bands make enough information spatially and thermal makes more different radiometric and spectral information than visible. However low spatial resolution is the most important limitation in thermal infrared bands. Using satellite image fusion, it is possible to merge them as a single thermal image that contains high spectral and spatial information at the same time. The aim of this study is a performance assessment of thermal and visible image fusion quantitatively and qualitatively with wavelet transform and different filters. In this research, wavelet algorithm (Haar) and different decomposition filters (mean.linear,ma,min and rand) for thermal and panchromatic bands of Landast8 Satellite were applied as shortwave and longwave fusion method . Finally, quality assessment has been done with quantitative and qualitative approaches. Quantitative parameters such as Entropy, Standard Deviation, Cross Correlation, Q Factor and Mutual Information were used. For thermal and visible image fusion accuracy assessment, all parameters (quantitative and qualitative) must be analysed with respect to each other. Among all relevant statistical factors, correlation has the most meaningful result and similarity to the qualitative assessment. Results showed that mean and linear filters make better fused images against the other filters in Haar algorithm. Linear and mean filters have same performance and there is not any difference between their qualitative and quantitative results
The effects of low level laser therapy (Ga- Al- As) on myofascial pain dysfunction syndrome
Muscular pain is one of the most common causes for facial pain. Myofacial pain dysfunction"nsyndrome (MPDS) is one of the most important disorders of facial area that affected patients suffer from"npain, tenderness of one or more masticatory muscles and limitation of movements. Lack of specific and"neffective therapeutic method, makes it necessary to find a treatment to decrease pain. Considering the"nanalgesic and anti- inflammatory effects of low-level laser, some investigators have recommended it for"nMPDS patient's treatment. In this study, the effects of low level laser (Ga-Al-As) on MPDS patients"nreferred to dental faculty of Tehran University of Medical Sciences, were investigated. Twenty- two"nMPDS patents, with mean age 33.32 years, were treated for 4 weeks (12 visits). Clinical examinations"nwere performed in 6 stages. The results of this study showed that variables such as pain severity, cheek"npain, pain frequency and tenderness of masseter, temporal, internal and external pterygoid muscles, had a"nstatistically significant improvement at the end of treatment with low level laser (GA-A1-AS) which"nlasted for three months, (follow- up period). Results of this study showed that, low-level laser therapy"nhas a sedative effect on the pain and tenderness of masticatory muscles in MPDS. Patients and having an"naccurate and regular program to complete treatment period, has an important role in MPDS"nimprovement

Alteration of liver biomarkers in patients with SARS-CoV-2 (COVID-19)
Introduction: Coronavirus disease 2019 (COVID-19) emerged in China and spread world-wide. In this study, we assessed the characteristics of markers of the liver in patients with COVID-19 to provide new insights in improving clinical treatment. Patients and Methods: We recruited 279 patients who confirmed COVID-19 and the data of liver biomarkers and complete blood count of patients were defined as the day onset when the patients admitted to the hospital. Results: The average of LDH value was 621.29 U/L in all patients with COVID-19, and CPK was 286.90 U/L. The average AST was 44.03 U/L in all patients, and ALT was 31.14 U/ L. The AST/ALT ratio was 1.64 in all patients. The measurement of CRP was increased by 79.93% in all patients. Average ALT and AST values of patients with elevated ALT were significantly increased in comparison to patients with normal ALT (P-value = 0.001), while AST/ALT ratio was significantly decreased compared to patients with normal ALT (P-value= 0.014). In addition, the average LDH of patients with elevated ALT was significantly increased compared to patients with normal ALT (P-value = 0.014). Conclusion: Hepatic injury and abnormal liver enzymes related to COVID-19 infection is an acute non-specific inflammation alteration
