The effect of cadmium on hematological and biochemical indices of silver carp (Hypophthalmichthys molitrix) exposed to subacute (0.65ppm) and acute (3.25ppm) concentrations for 96-h test period was assessed. The results showed that Hb, Hct, RBC and MCV significantly decreased in low concentration of cadmium (p<0/05), while MCH, MCHC, WBC, glucose and cortisol were significantly (p<0/05) higher than control group in both low and high concentrations. This study reveals that some hematological and biochemical indices of silver carp, such as cortisol, can be used as suitable biomarkers in tracing Cd²⁺ contamination within water bodies.

This study reports the incidence of histological alterations in morphometric changes in the liver and ovary of Acanthopagrus latus collected from an urban stream impaired by anthropogenic activities and from a clean site (reference). Mercury concentration was determined using a standard cold vapor atomic absorption. The results showed that mercury concentration at the creek waters, and specially sediments along Mahshahr coast, was higher than in the other marine environment, and in Zangi was lower than in the other sites of sampling. Several liver lesions were identified, including enlarged and lateral nuclei, nuclear degeneration and vacuolation, oncotic, apoptic, focal, massive, centrilobular and periportal  necrosis, atrophy, lipidosis, hydropic and cloudy swelling, oval cell proliferation, cirrhosis, hemorrhage, macrophage aggregates, bile stagnation, dilation of sinusoid, intracellular edema, and dark granules. Ovary histology revealed some changes in higher concentrations such as increase in the number of pre-vitellogenic oocytes, oocyte atresia, and adhesion in the ovaries of females that were sampled from the sites with high concentration of mercury. In this study, existence of mercury in Mahshahr coast is demonstrated and high incidence of histological alterations in the liver and ovary of A. latus is an evidence of the poor environmental quality of creek waters. Hence, histopathological changes were induced by the mercury adversely affected the proper functioning of these organs in these fish.

The present study investigateeffect of different dietary macronutrient composition on fatty acids profile, body fat and pancreatic lipase enzyme activity in Siberian sturgeon. A group of 180 Siberian sturgeons juvenile (initial weight, 30 ± 5 g) were used in this experiment and fed on four isoenergetic diets. Diets were named LP-St (low protein and high carbohydrate: lipid ratio), HP-St (high protein and high carbohydrate: lipid ratio), LP-L (low protein and low carbohydrate: lipid ratio) and HP-L (high protein and low carbohydrate: lipid ratio). Fish were fed apparent satiety for 10 weeks. The samples were obtained from body carcass and juveniles intestine. In this study, the same level of fish oil and sunflower oil were used as a source of diet lipid content. The HUFAs content in HP-St and LP-L diets were showed highest and lowest value, respectively. The results showed the body fatty acidsprofiles was significantly affected by fatty acids composition in diets (P < 0.5). Diets with high protein and high carbohydrates concentrated SFA and MUFA in fish carcass. Moreover, the PUFA content increased in sturgeon fed with high lipid diet. However,the results of this study showed the body lipid content wasaffected by total lipid content of diet and lipase activity decreased in Siberian sturgeon intestine fed on LP-L diet with lowest HUFA.

Research subject: Saponin compounds have been considered as anti-cancer, antimicrobial, antifungal, anti-inflammatory, and antiviral activity agents. In addition, they are also used as foaming agents in some food industries. There are few studies for assessing the extraction of this substance, so far. The main purpose of this study is to assess and compare the extraction yield of Saponin by conventional extracting using solvent and super-critical fluid method.
Research approach: In the extraction with solvent, the effect of three independent parameters including mass of solid material, percentage of ethanol solvent, and time of extraction on process performance was investigated. Yield of extraction and Saponin concentration were considered as indexes for evaluating the process performance. In the super critical fluid extraction, the effects of extraction time, pressure, and temperature were investigated. In this method, carbon dioxide was used as super critical fluid and 80% ethanol was used as co-solvent. In order to design of experiment and process optimization, response surface methodology and central composite design was used.
Main results: In optimum condition of extraction with solvent, the mass of solid material, ethanol solvent percentage, and extraction time were 5.4 g, 77.5%, and 7 h, respectively. In this condition, the maximum efficiency of extraction yield of 1.12 mg of saponins per a gram of dry primary substance was obtained. The results indicated that time and solvent percentage were significant parameters.  Further, interaction between two factors of time and solvent percentage was significant. For supercritical fluid extraction, in optimum condition, extraction time, pressure, and temperature were 10 h, 400 bar, and 50 °C, respectively. Extraction yield in this condition was 20% more than the yield of conventional method. It is concluded that the supercritical fluid extraction method has higher performance than conventional method.

The effect of cold-smoking was studied on the production of polycyclic aromatic hydrocarbons (PAHs), quality indexes, microbial community and omega-3 fatty acid profile of common carp. Thus, the fresh fish was smoked and stored for 30 days at 4^°C. The nutritional values of both fresh and smoked products (protein, lipid, moisture and ash), pH and TVB-N indexes, microbial count including TC, molds and yeasts, were determined and polycyclic aromatic hydrocarbons PAHs, carcinogenic PAH₄ compounds and also fatty acids composition were determined using HPLC and GC, respectively. The results showed that microbial community was well controlled and moisture content decreased during smoking, thus protein and lipid content were increased (P<0.05). TVB-N index for fresh fish was 10.87 and increased to 14.01 and 18.10 mg/100 in smoked and 30^th days of production, respectively (P<0.05). High molecular weight of PAH₄ were evaluated at 0.20, 1.70 and 1.30 µg/kg, respectively (P<0.05). No benzo[a]pyrene as a carcinogenic hydrocarbon in fresh fish was found, while it was found during smoking process (0.40 µg/kg) and after 30 days of storing (0.30 µg/kg) (P<0.05). The ω-3 fatty acids were determined in a range of 5.38 and raised to 5.53 g/100g in smoked fish and 5.47 g/100g after 30 days, which was insignificant (P>0.05).The results also showed that cold-smoking and one month storing at 4^°C didn't change the composition of carp fatty acid, and useful series such as ω-3, ω-6, EPA and DHA were well preserved.

The Iranian architecture is one of the richest local architectural samples in the world that its achievements are undeniable. Features such as civility, autonomy, avoidance of absurdity and … were used as main branches in the architecture of ancient monuments. With advent of Islam and its spread in Iran, Iranian architecture was combined with values derived from religious and created the Iranian-Islamic rich architecture principles. In the historical monuments of Iranian cities including Boroujerd, it can be seen the application of Iranian-Islamic rich architecture such as harmony with nature, security, identity and … in that period. After decade 1300 and by opening the doors of Iran to the world countries, the western architecture entered in Iran and it has prevailed in competition with Islamic-Iranian architecture and after that, the Iranian buildings were built with western principles. The architecture that was very different with Islamic-Iranian culture and perhaps it was in conflict with it that its prominent sample can be seen in the contemporary houses including Maskan Mehr, a program which has been in the government agenda in order to provide house for low-income people.
In the last half-century, inter-family distinction has increased dramatically and its internal congruence has changed. in other hand, Urban growth and increasing middle class has increased External similarities in families. the terms as such as "middle class", "low-income group" etc are signs of "same view" viewpoint. In the West the family is known as an entity through which Most legitimate emotional and sexual relationship and wealth transfer are possible and includes parents and one or two children. Parents often work together and come home in the evenings and home is becoming dormitories. But in Iran, Families in both quality and quantity terms is more varied and multiple. Presence of children over 20 years old and relatives(Grandfather, grandmother and . . .) in a iranian home has very high possible.
Art and culture of this zone combined with new factors. Principles, customs, Religious Ceremonies, spirits, ethical, thoughts, and ideas of generations and other human features are presenting not only in massive buildings but in Small buildings, and is such entwined with the essence of existence Iranian architecture that its effect can be traced in all past Architectural monuments.
Islamic-Iranian Architecture has a bilateral relationship with nature, Such a way In all architectural monuments of the cities a summary of the nature is created. in the Islamic-Iranian city, Buildings have a central courtyard where residents have the opportunity to see the sky, stars and sun and inside it there are also waterfront and plants. So, the small-scale relationship with nature in house and in closest state is created. materials used in Building Construction include natural material and specially Soil which has not The destructive effects on natural environment and When Building is destroyed this materials are Recyclable and reusable. In addition, The orientation of these buildings is in a way which it best utilization natural factors (Sunshine, Winds, precipitations) is possible. While in some parts due to the needs by creating elements such as Windward and areas such as Bedchamber and Shvadan convert possible Natural threats into opportunities. also The use water resources is doing So that do not cause Pollution of it and maximum exploitation from this resource can be possible.
it must be said , unfortunately , Islamic architecture in iran has distanced from its Islamic and indigenous form , and created overt and covert problems , including loss of natural light location , impose many restriction . Koran's emphasis is on the home location and this residence before its physical concept have metaphysical meaning and means a dwelling and calm spirit , and it requires that templates of forms of housing in Islamic community will be realizes based on this meaning. therefore in this model , architectural pattern is prior to the mold and idea oriented . on the other hand , spirit shapes in the form and templates.
Examining the trend of change housing at different time telling the story of transformation of this space . housing pattern used prior to 1300 is very different with current pattern . home in its Iranian and also Islamic sense. House in its Iranian view is a completely enclosed space that constructed based on minorities and cultural condition of its time and use all places and circumstances in the best way. In this type of housing , there is comfort along with psychological , visual and audio security , and its residents have been living in the appropriate environment.
After 1300s , architecture of iran following West was changed that was in conflict in all areas . this contemporary home conflict is obvious . examining the Maskan Mehr in Borojerd showed this conflict better . studies show that Maskan Mehr in Borojerd have not bean constructed according to Iranian – Islamic model none of Iranian – Islamic architectural principle do not have been observed , so that with following West architecture and culture , Iranian values have been ignored and houses have been constructed similar to west's houses. In this respect the privacy( visual , audio, security) of the home have not been observed. If door is opened , you can see the interior of the house . house spaces in these houses is include closed space that most of its parts are scrambled , and person should define this space . space in these house is worth by objects not by elements such as walls . floors and ceilings.
The purpose of this study is to present an Islamic-Iranian model in the Maskan Mehr and The methodology of this thesis is descriptive-analytical that some part of its data were collected as library method and the other part is provided via field visit and completing questionnaire.
The results indicate that the Maskan Mehr in the light of architecture, based on observations and experts, features of Islamic-Iranian architecture can't be seen in that and the application of western architecture is evident inside the building and also its façade.

Due to the increasing demand for nanotechnologies, there is a rising concern about the potential risks of nanomaterials to human health, environment, and aquatic ecosystems. The chemical composition and small size of the nanomaterials are the most important factors in the toxicity of these materials. Histological study of gill and investigation of haematological parameters are important for monitoring of the health status in aquatic animals. Therefore, in this study, the effects of subacute concentrations of copper oxide nanoparticles were examined on some haematological parameters of Caspian Roach (Rutilus rutilus). The experiment was performed at 15 litres aquariums in three experimental groups including 10, 40, 80 ppm copper oxide nanoparticle and the control group for 42 days. Each treatment included three replicates consisting of seven juveniles carp with an approximate weight of 42± 2 gr. The results of this experiment showed that copper oxide nanoparticle caused hyperplasia, lamellar fusion, epithelial hypertrophy, lamellar aneurism, and reduces secondary lamellae length. In addition, red blood cells (RBC) was significantly decreased with the increase in the concentration of copper oxide nanoparticle (P<0.05). At the end of treatment, RBC had a significant reduction from 2.11±0.004 to 1.98±0.005. Hematocrit and haemoglobin reduced from 1.37±0.011 to 1.34±0.001 and 7.8±0.01 to 6.9±1.32, respectively (P<0.05). A significant reduction was recorded in hematocrit among the control groups and other treatments (P<0.05). Conclusion: Eventually it can be concluded that the sub-acute particles may causes damage to the surface of tissues, especially gill tissue, and changes in the level of blood factors in fish, which can be due to the destructive effects of this type of nanoparticle on hematopoietic organs such as liver and kidney. Therefore, a definite conclusion in this regard requires more and more extensive research on the same species and other species.

Background: Biofilm is described as an accumulation of microbial organisms connected to a living or unmoving surface mainly through self-secreted polymeric materials. With a complete understanding of biofilm behaviors and the role of rhamnolipids in its stability or dispersion, a new path could be designed in the treatment of infections like Pseudomonas aeruginosa (P. aeruginosa). The purpose of this study was to investigate the role and function of rhamnolipids in P. aeruginosa velocity and biofilm formation ability.
Materials & Methods: In this study, 68 P. aeruginosa clinical samples were isolated from February 2022 to 2023 and confirmed based on culture and molecular methods. The presence of genes associated with di-rhamnolipid (rhlC) and mono-rhamnolipid (rhlA and rhlB) biosynthesis was detected by PCR method. For velocity assay, bacterial cultures on Bushnell Haas medium were monitored for 24 and 72 hours (0.5%).
Findings: The results showed that the distribution of biofilm strength among P. aeruginosa strains was normal. The frequency of rhlC was significantly different from those of rhlA and rhlB (p= .01). In the first 24 hours, the velocity of P. aeruginosa on Bushnell Haas with glucose was 2 µm/min and decreased during 72 hours. But after 72 hours, the velocity of moderate and weak biofilm-producing strains on solid medium with glycerol was constant.
Conclusion: In this study, rhamnolipids produced from different carbon sources showed different behaviors on colony shape, velocity, and strength of bacterial biofilms.

Malathion and diazinon are widely used organophosphate pesticides in the agriculture fields, especially in the north provinces of Iran. In the current study, lethal concentrations of diazinon and malathion were determined based on big head carp calculated death rates at 24, 48, 72 and 96 hours using probit analysis. Then, in a separate experiment and according to the obtained LC₅₀, the effects of these toxins on fish hematological parameters was evaluated in which fish were disturbed in 10 treatments with 3 replicates (4 different doses of diazinon, 4 different doses of malathion and 1 control for each toxin) for 7 days. Fish were exposed to different sub-lethal concentrations of each toxin (12.5, 25, 37.5 and 75% of lethal concentration (LC50 96h). After 7 days, blood samples were collected and hematological parameters including hematocrit, hemoglobin, red blood cells count, the total number of white blood cells and white blood cell differential count (the percentage of lymphocytes, monocytes, neutrophils and eosinophils) were examined. The results of acute toxicity test showed that diazinon is more toxic to big head carp compared to malathion. Also, hematological studies of big head carp exposed to diazinon showed a significant reduction in red blood cells and white blood cells with increasing toxin concentration. Meanwhile, the percentage of neutrophils remarkably increased while lymphocytes significantly decreased along with increasing the concentration of diazinon.

Collisions between a bird and an aircraft, known as “bird strike event” is a common and dangerous phenomenon in aviation industry. In this study, three numerical methods namely Lagrange, Smoothed Particles Hydrodynamics (SPH) and Arbitrary Lagrangian Eulerian (ALE) have been implemented in order to investigate bird strike incident. The results have been compared with each other and also with exeperimental data. In order to compare the results obtained from three methods, pressures at the center of impact and also deformation of bird models have been compared. Results indicate that all the three methods are able to predict the pressure at the center of impact almost accurately in both perpendicular and inclined impacts. In addition to that all the methods are able to predict same deformation of bird at particular time intervals. Shorter solution time, not having much parameters to deal with and low probability of numerical errors make the SPH method as a good candidate to analyze bird strike problems.

One of the important applications of Expanded Polystyrene (EPS) in Iran is its use as infill block in Block and Joist Reinforced Concrete Floors. The properties and performance of EPS blocks in this floor system, including reaction-to-fire, mechanical properties, thermal resistance and acoustical performance of the system, was studied. Fire behavior of blocks was tested with ISO 5660 cone calorimeter test method. The fire properties of standard and flame retarded types of EPS were measured and discussed, including time to ignition, average and peak values of heat release rate and total heat release. The influence of type of EPS on its fire behavior was investigated. The results showed that the time-to-ignition and total heat release parameters can not be a characteristic value for distinction between standard and fire retarded types of EPS under cone calorimeter test condition. The reason is that both types are flammable and burn completely at fire temperatures. The peak value of heat release rate (PHRR) of EPS is the most important parameter that can be utilized for distinction of Standard and flame retarded types of EPS with cone calorimeter test method. PHRR values higher than 300 kW/m 2 were achieved for standard types, but the results for flame retarded ones were less than 250 (and mostly less than 200) kW/m     2 . The fire risks of specimens were also evaluated using Conecalc software and Richardson method. The results showed that even flame retarded   EPS needs to be protected with a thermal barrier in building applications. Moreover, it is required that the   protective barrier be mechanically fixed to the structural system, since EPS melts and recedes away heat,   once it is exposed to high temperatures. Hence, it is not able to keep barrier, say plaster, in its position.   The flexural strength of blocks under static and dynamic loads and its relation with density and   dimensions of blocks was evaluated. The results showed that minimum 12 and 14 (kg/m     3 ) density of foam is required respected for 25 and 20 cm of height of blocks with a width of 50 cm. An optimum 27      2 mm was obtained for the width of sitting section of blocks on joists. The influence of different properties and   geometry of EPS block (conductivity, width, height and existence of a thermal covering layer under joists)   on thermal resistance of floor system was also studied. The THERM software, Enery Efficiency and   Renewable Energy Program, was used for evaluation of thermal resistance of the floor. The increase of   height and width of blocks caused improvement in thermal resistance of the floor system, but the best result   was obtained when a thermal covering layer was considered under the joists. The acoustical results showed   that the replace of EPS blocks with hollow clay blocks does not influence importantly the impact sound   insulation of the floor system. Neither of them can fulfill the impact sound acoustical requirements and   need to be improved with an extra system, like a floating floor or an appropriate elastic floor covering for   this purpose.

Objective: The theraputic exercise is regarded as one of the most important theraputic interventions in the chronic low back pain patients. Stabilization exercise is among the most significant practical ones in these patients. The study of the effects of these exercises on the variability of trunk muscles postural strategies and the ability in normalizing these strategies are among the uncertainties that have remained unknown up to the present time. The purpose of this research is the study of the effect of stabilization exercises on the variability of postural control strategies in these patients. Materials and Methods: The study was performed on 21 (14 males, 7 females) recurrent non-specific low back pain patients. The electromyographic activity of Deltoid, Transverse Abdominis/Internal Oblique, External Oblique and Erector Spinae muscles of each person was recorded in 75 rapid arm flexion with maximum acceleration. Then, 14 individuals were placed in the experimental group and 7 in the control group randomly.The experimental group performed isolated abdominal hollowing and bracing exercises using pressure biofeedback with the supervision of a physiotherapist in different positions including supine, sitting on a chair, standing still and standing with rapid arm raises with maximum acceleration once a day, for 20 sessions. The variables studied in this research were evaluated in both experimental and control groups after the training sessions. The standard deviation of the trunk muscles onset latencies relative to deltoid muscle was statistically analyzed by a dependent t-test in both groups. Results: The results revealed that performing the stabilization exercises increases the variability of the timing of anticipatory postural adjustments in TrA/IO in the experimental group (P=.037), while there were no significant changes in the variability of EO (P=.0346) and ES (P=.673) muscles in these patients. The variability of the timing of the anticipatory postural adjustment in TrA/IO (P=.199), EO (P=.702) and ES (P=.465) muscles did not show any significant changes in the control group. Conclusion: The study of the results showed that the reduction in the variability of postural control system in recurrent non-specific low back pain patients as a factor that causes the continuity of back pain can be improved by goal-directed stabilization exercises.

Sensory indices, microbal communities, qualitative parameters and fatty acids profile of smoked Kutum and Golden Mullet were evaluated at the Northern Iranian markets. Thus, the samples from selected markets were collected and analyzed and compared also with acceptable ranges. The results showed that there were differents in some indices between smoked Kutum and Golden Mullet such as color and texture as sensory, pH (6.30 and 7.74% respectively), total lipid (7.67 and 6.20 respectively), TBA (1.981 and 1.845 meqO₂/kg respectively) and FFA (0.95 and 1.22 % respectively) as chemicals and total muld and yeast (2.93 and 3.25 Logcfu/g, respectivly) as microbal communities (P<0.05). The results also showed that Halophillic and Anaerobic bacteria had higher and lower loads in smoked fish, respectively. While there were no differents in EPA and DHA fatty acids but most series like PUFA (30.35 and 19.67 g/100g), omega-3 (8.73 and 11.19 g/100g), omega-6 (21.52 and 8.49 g/100g) and ω-3/ ω-6 ratio (0.40 and 1.32) showed a difference between smoked Kutum and Golden Mullet, respectively (P<0.05). The results stated that chemical indices, nutritional values and microbal communities were in acceptable and freshness ranges in smoked products and their valuable fatty acid series were preserved.

In this paper, the experimental behavior of grid cylindrical composite structures which are used widely in engineering structures under ballistic impact is investigated. In the present study, the grid cylindrical composites were manufactured by the filament winding process with fiber placement procedure and perforated by projectile using the ballistic gas gun. Input and output velocities of projectile were recorded. The results show that presence of discrete ribs prevents spread damage from one cell to it’s adjacent cells and structure behaves differently against projectile with velocity near ballistic limit velocity and higher velocities. With approach to the ribs location ballistic limit has been increased. However due to reduce fracture area, overall and local deformations after impact in velocity which is higher than ballistic limit velocity, projectile has been came out from grid samples with higher velocity than simple composite shells. In this paper, delamination in outer composite shell and ribs, debonding between shell and ribs, residual velocity of projectile, fracture area of the grid specimens and the effects of curvature in two deferent velocities were reported and commented upon as results.

Due to the extreme increase in computational power over the recent years, numerical methods have gained the most proportion in analyzing composite structures and components because of the consideration complicated failure mechanisms such as delamination, fiber buckling and fiber breakage, matrix cracking, debonding ribs of skin and a combination of mentioned failure mechanisms. However exact three - dimensional modeling damages caused by impact phenomena is still a challenge. In present numerical work, the most advanced modeling techniques have been used to predict the behavior of composite structure under high velocity impact. The ribs and layers have been modeled using solid elements and a user defined material model with modified puck and Hashin (3D) failure criteria was implemented. Because these failure criteria do not exist in Commercial version of the Abaqus software, we have used Fortran software for writing these criteria so this capability was added to the software. Figures of velocity variations and force variations of projectile, damaged area, different mechanisms of fracture were reported as results and commented upon. In this study, The numerical results have been validated with experimental data and show very good agreement.

The current study represents the influence of nanoclay on buckling behavior of glass fiber reinforced polymer (GFRP) grid-stiffened nanocomposite shells. The nanocomposite grid shells were manufactured from continuous glass fiber using a specially designed filament winding machine. The epoxy/clay nanocomposites with different clay content (0%, 1.5%, 3% and 5% of clay) were used as the matrix of the grid stiffened structures. The state of dispersion and mechanical properties of the epoxy/clay nanocomposites were obtained by X-ray diffraction (XRD) method and uniaxial tensile test, respectively and also the grid structures were loaded under uniform axial compression test. The results of XRD show that the clay has been further intercalated by the epoxy matrix. The tensile test results represent that the tensile modulus and Strength, strain to break and energy to break of the epoxy/clay nanocomposites increase with adding clay loading into the epoxy resin. Furthermore, it is found that the critical buckling load of the cylindrical grid samples increases continuously with increasing the clay content up to 5 wt. %. The maximum value of improvement in the critical buckling load is about 10% for the samples with 5 wt. % of nanoclay.
