- چکیده انگلیسی: Children in elementary school ages due to entering the new era of their life are more high risk of facing with wrong food habits that have been associated with noncommunicable diseases. This study was conducted to assess obesity/overweight status and lifestyle behavior (diet, physical activity and screen time) in 7-12 years children in Buin-Zahra health network. The data of 120 children from “SIB system” was collected in January 2018 as a cross-sectional study. It consisted of weight, height, amount of fruits, vegetables, dairy products, and junk foods intake, physical activity and screen time. Z-score for height for age (HAZ), body mass index for age (BAZ) and weight for age (WAZ) were calculated using World Health Organization reference data. Anthropometric assessments revealed obesity (BAZ>2) in 6.6%, thinness (BAZ<-2) in 13.3% and stunting (HAZ<-2) in 4.1% of children. Stunting and thinness were significantly more common in males. Fruit, vegetable and dairy products intake and screen time were more in females. A strong positive correlation between screen time and age was significant at the 0.01 level. There are substantial rates of stunting, thinness, and obesity in 7-12 years children. The results suggest the need for evaluating health caregivers’ educational methods to improve nutritional status in children.

- چکیده:
- چکیده انگلیسی: The conversion of coal into high-quality fuels is carried out through gasification, syngas production and the process of Fischer-Tropsch. Additionally, produced syngas derived from coal gasification only can generate power and heat in a combined cycle power plant. In order to combine these two methods together in an integrated process at the same time, it is necessary to use part of the produced gas for the production of heat and power, and the other part for the production of liquid fuel. As a result, this new and integrated process will consist of three major parts: "coal gasification", "power and heat generation" and "production of liquid fuel". The purpose of this study is by consideration of an integrated gasification combined cycle (IGCC) plant with input feed of coal, an integrated system of "Combined heat and power as well as liquid fuel of Fischer-Tropsch", called in this research CHPF is designed, and the optimum amounts of production of the power, heat and liquid fuel are provided at a certain scale of the feedstock. Thus, the various parts of this integrated process is designed conceptually, and simulated and integrated with Aspen software; then an objective function is defined to maximize the revenue from the sale of process products (power and liquid fuels). To ensure the accuracy of the results, the sensitivity analysis tool is used; and the simulation and design results are compared with an experimental work, indicating that the difference in results is about 4%.

- چکیده:
- چکیده انگلیسی: Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving, is possible. In the present paper, a novel mixed fluid cascade natural gas liquefaction process is investigated by exergy and exergoeconomic analysis methods. In this process, one of the vapor compression cycles is replaced by water-ammonia absorption refrigeration cycle. The simulation results show that the compressors of this plant are responsible for 43.2% of total exergy lost. Decision variables of the system are consists of mass flow ratio of the tower’s bottom product (bottom feed ratio), number of trays, and compressor’s pressure ratio. Choosing appropriate values for these variables will result in 12% increase in exergetic efficiency of the plant. Exergoeconomic factor of water coolers, heat exchanger no.1 and tower no.1 shows that these components respectively impose a sizable capital cost to the entire system and does not result to a reasonable capital recovery. In this paper an integrated structure of producing liquid fuels from coal using Fischer-Tropsch synthesis and some equipment such as gas and steam turbines as well as HRSG heat exchanger for recovering of heat and power has been developed. Gasification method because of high efficiency and exothermic nature from energy consumption point of view is employed for producing synthesis gas.

- چکیده:
- چکیده انگلیسی: Abstract
The Aitamir Formation is divided into two members the lower sandstone and the upper shale. 32 genera and 57 species of foraminifera have been recognized. According to identified foraminifera Rotalipora appenninica Interval Zone, Rotalipora globotruncanoides (Rotalipora brotzeni) interval zone and Whiteinella aumalensis-Dicarinella canaliculata assemblage zone are proposed and a l Albian-l Cenomanian age is attributed for upper shale member of the Aitamir Formation. Palaeoecological studies led to recognition of three calcareous, two agglutinated benthic and three planktonic foraminifera morphogroups. In the lower one third of shale member, the planktonic foraminifera are more abundant than agglutinated benthic foraminifera, while in the upper one third, the frecuency of all morphogroups increase. Calcareous benthic morphogroups could be attributed to aerobic, shallow to slightly deep water, oligotrophic environment; while the agglutinated benthic morphogroups show aerobic, mesotrophic to eutrophic condition that are characterized by a dominance of arenaceous shallow infaunal specimens which are active deposit feeders. Planktonic foraminifera morphogroups with trochospiral and smooth test show that may have lived near the surface water in the aerobic to semi aerobic environmental conditions. The increasing number of planktonic foraminifera and specially keeled species could suggest recovery in paleoenvironmental conditions.- انتشار مقاله: 20-12-1395

- چکیده انگلیسی:            Abstract  The Abtalkh Formation in the Kopeh-Dagh basin in northeastern Iran with an age of Late Cretaceous (Turonian â Santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. Thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. Assuming the average MS magnitude as the proxy for mean sea level, positive Magnetic Susceptibility (MS) values were considered to present sea level falls and negative values for sea level rises. Based on these data a curve showing water level fluctuations throughout the stratigraphic column was prepared which shows a general trend of regression from base to the top of the formation. To test accuracy of this method, magnetic susceptibility results were compared with those gained from palynology and palynofacies studies and with those from geochemical analyses. Based on the changes in palynological factors (e.g. the terrestrial/marine particles ratio, chorate/proximate, proximochorate, and cavate dinocysts ratio, differences in dinoflagellate assemblages, rarity and abundance of dinoflagellate groups), palynofacies and fossil contents, three Third-order sequences were differentiated, confirming the results gained from magnetic susceptibility method. In addition, the results gained from Rock-Eval pyrolysis indicate that the Abtalkh Formation at the type section was deposited under an oxic condition and confirm the results gained from palynology and magnetic susceptibility.        * Corresponding author: 09122104954 Email : eghasemi@khayam.ut.ac.i r

- چکیده:
- چکیده انگلیسی: The domestic water buffalo (Bubalus bubalis) is an economically important livestock species in many Asian and Mediterranean countries. Two types of water buffalos are river and swamp buffaloes. Genetically, the swamp buffalo has 48 chromosomes (2n = 48) and the river buffalo has 50 chromosomes (2n = 50). Khuzestan province is one of the important centers of buffalo farming in Iran. Since there was no cytogenetic information about Khuzestani buffalo breed, the present study was performed to provide karyotype and cytogenetic study in Khuzestan buffaloes. In this study, blood samples of 40 buffaloes were collected randomly from jugular vein via heparinized syringes. For metaphase smear, blood samples were cultured in RPMI 1640 medium containing fetal bovine serum and phitohemaglutination and then transferred to water bath for 69 hr. After stopping cell division by colcemide and using fixed solution, from each sample six slides were stained with Giemsa staining. Based on the results, number of chromosomes of the Khuzestani buffaloes was 50 (2n = 50). Among the 25 pairs of chromosomes, the first 5 pairs of autosomal chromosomes were sub-metacentric, 19 pairs of autosomal ones were acrocentric and the sex chromosomes (X and Y) were acrocentric. Furthermore, X and Y chromosomes were the largest and smallest acrocentric ones, respectively. Therefore, the buffaloes of Khuzestan province are considered as a river type.

- چکیده:
- چکیده انگلیسی: In this study morphological characterization of leukocyte and erythrocyte were investigated in central Asian tortoise (Testudo horsfieldii) in Iran. 7 males and 7 females were used in this study. Erythrocyte and leukocyte morphology were described using Wright´s technique. The sizes of erythrocyte and their nuclei were measured using an ocular micrometer under objective lenses (100x). Results of this study were compared with previous work on the other reptile species. Because there were no significant differences between the erythrocyte size of female and male tortoise, the data from the females and males of individual species were pooled. The mean length of mature erythrocytes was 1.98 µm (± 0.16 SD, with a range 1.10 - 2.50 µm).The mean width of mature erythrocytes was 1.10 µm (± 0.14 SD, with a range of 0.80 - 1.90 µm).The mean length of nucleus was 0.71 µm (± 0.09 SD, with a range of 0.50 - 1.00 µm). The mean width of the nucleus was 0.52 µm (± 0.07 SD, with a range of 0.40 - 0.70µm). Five types of leukocytes were found in the tortoise blood namely basophiles, eosinophils, lymphocytes, heterophils and monocytes.

- چکیده:
- چکیده انگلیسی: Background: This study was conducted to evaluate the clinical outcomes of the acromioclavicular joint (ACJ)
fixation with hook plate (HP) and continuous loop double endobutton fixation (CLDE) in the treatment of acute ACJ
dislocation.
Methods: This retrospective study was conducted on eight patients with HP and nine patients with CLDE fixations for
acute ACJ dislocations. The subjects were evaluated by various criteria, including disabilities of the Arm, Shoulder,
and Hand (DASH), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment (ASES), University
of California, Los Angeles (UCLA) shoulder rating scale, Shoulder Constant score, Simple Shoulder Test (SST), and
coracoclavicular (CC) distance.
Results: The differences between the mean scores of the visual analog scale for pain, DASH, ASES, UCLA
shoulder rating scale, and Shoulder Constant, and SST were statistically significant in favor of the CLDE group.
Mean difference of CC distance was 8.6±0.9 mm in the HP group; however, it was 11.6±1.2 mm in the CLDE group.
The operation time was shorter in the HP fixation, compared to that in the CLDE fixation (51±13.3 versus 105±9.7
min; PHP group.
Conclusion: The CLDE fixation was reported with better clinical outcomes than HP fixation; however, it was a technically
demanding procedure. The HP maintained the CC distance better than CLDE with a technically easy application. The
HP requires a second surgery for the removal and development of subacromial erosion and osteoarthritis of the ACJ
that can be regarded as major concerns.
