Our findings revealed plastic litter that was disposed by beach visitors and those cast into the sea from ships in beaches contained total mercury (T-Hg) causing toxic effect to marine lives. Direct mercury analyzer (DMA-80) with the least detection limits of 0.0015ng.g-1was used for this purpose. Toxicity (96 hr) and bioaccumulation tests for 180d with the inclusion of common beach plastic litter to selected crustacean Portunus pelagicus (blue crab) and mollusc Tapes sulcarius (Furrowed Venus: Cockle) revealed high T-Hg concentrations and bioaccumulation factor (BAF)>1 in all the experimental combinations labeling them as hyper-accumulators. The novelty of this study is the determination of ‘adsorbed’ and ‘absorbed’ T-Hg levels in marine organisms from plastic materials that were once considered as non-degradable materials. Database from this study could be used to prevent human consumption of contaminated seafood besides evaluating the apportionment of plastic materials and its contamination through transportation in beaches elsewhere the globe.

The species was found associated with Pinus khasyia, Pinus caribiae, Pinus petula and Cryptomeria japonica, Canarium resiniferum, Dipterocarpus macrocarpus and Tectona grandis. Taxonomic history, Macro and Micro morphological characters of all taxa are illustrated.
Fish protein hydrolysate was produced from the viscera of bighead carp (Hypophthalmichthys nobilis). Hydrolysis conditions (enzyme concentration (%), temperature (°C), and time (min)) were optimized using response surface methodology (RSM). A factorial design was applied to minimize enzyme utilization and modeling the degree of hydrolysis and protein recovery (with R2 values of 0.95 and 0.90, respectively). Lack-of-fit test revealed a non-significant fit for the model, indicating that the regression equation was adequate for predicting the degree of hydrolysis and protein recovery under any combination of the variables (P<0.01). The optimum conditions to reach the degree of hydrolysis of 20% were 45.12°C, 22 min, and a Promod® concentration of 1.34% of sample. The optimum conditions for protein recovery (to the highest PR; 68%) were 47.04°C, 30 min and Promod® concentration of 2.17% of sample protein. The spray-dried bighead carp visceral protein hydrolysates had relatively high protein (69.5%) and low lipid (2.5%) content. The most essential amino acids in protein hydrolysates produced by Promod® were leucine and histidine, and the most flavour-causing amino acid was glutamic acid.
Exploitation of mangrove leaves and branches as fodder for domestic animals by rural populations was the main reason for undertaking this study on nutritive values of Avicennia merina as a forage species for feeding domestic animals. The objective of this research was to determine the forage quality of leaves, branches and roots of Avicennia merina from the Bordekhoon, northern part of the Persian Gulf. Samples (leaf, root, and branch) of plants were selected using the randomized sampling method in the Avicennia merina area. Samples were dried and analyzed at the laboratory by standard methods to determine the following parameters: dry matter (DM), nitrogen (N), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), dry matter digestibility (DMD), dry matter intake (DMI), metabolizable energy (ME), and relative forage quality index (RFQi). Statistical methods, including analysis of variance and principal component analysis were used for analyzing forage quality data using Xlstat® software. The results showed that different parts of the plant had significantly different forage qualities (P<0.05). The leaves and branches of Avicennia merina species had relatively high nutritive values, respectively.
The idea of this paper is to determine the efficiency of mechanical engineering secondary schools (MESS) in Belgrade District by the method of Data Envelopment Analysis (DEA method). The endeavour in the paper was to find, by means of DEA method, the solutions which would improve the work and efficiency of secondary schools, both mechanical (and other specialized schools) and high schools. Respecting the knowledge relating to the area of operation researches, especially in the area of activities of non- profit researches, such as schools, it can be concluded that in the researches during the past 10 years, it has come to the significant changes in our school system.
Aim: Effects of preemptive gabapentin on postoperative pain with a NSAID, and investigate the side effects for postoperative pain after laparoscopic cholecystectomies. \nMaterials and Method: 50 patients enrolled to the study. The patients were randomly divided into 2 groups 1 hour before the operation: Dexketprofen trometamol 25mg tablets perorally were administered to the patients of group D (n=25) and in addition to 25mg dexketprofen trometamol tablets, 800mg gabapentin tablets were administered to patients of group DG (n=25). Pain levels, time of first analgesic need, amount of morphine used, sedation levels with Ramsay Sedation Scale, patient satisfaction scores, advers effects, recorded at 2, 4, 8, 12, 18 and 24 hours after the surgery.\nResults: Total morphine consumption all postoperative times was lower in group DG when compaired with other group (PACU, p=0.021; postoperative 2. hour, p=0.007; Postoperative 4. hour, p=0.001; postoperative 8-12-18 and 24. hour, p<0.001). Also first analgesic requirement time was higher in group DG (p<0.001) and postoperative additional analgesic requirement was higher in group D (p<0.001). \nConclusion: Dexketoprofen trometamol -gabapentine combination can provide effective postoperative analgesia, than Dexketoprofen trometamol alone and also combination can provide less anxiety, morbidity, hospital stay and this reduce the hospital costs.
ABSTRACT\nIn this research we have investigated essentiall oil constituentsand antioxidant property of Pimpinella plant.aerial part of plant are collected from around sari mazandaran province, Iran. The chemical composition of the essential oil plant obtained by hydrodistillation using a clevenger. Compositae was analysedby GC-MS. The extract was carried out with soxhlet apparatus.For antioxidant activity investigation ,used of TPC,DPPH and FTC ,TBA method .then result by comparison of vitaminC antioxidant activity (natural antioxidant ) and BHT(synthetic antioxidant). 20 components were identified in the essential Oil, that 94.5% of total composition. The major components of essential oil from Pimpinellaplant were : α-pinene0.8%, couminalchol55.6%, carvacrol0.9%, terpinolene14.9%, limonen7.8%. α-pinene and limonene observed in composition have Antimicrobial and fungicidal properties.Limonene also used in providing of polymer,paste and perfume.in totally this Plant used that in cure of whooping cough and instigator cugh.Percentage of antioxidant were determined for ethanolic extract of plant under study 27% by FTC method , 63% for TBA method .By regards of this plant in iran natural ,essence of this plant as an natural antioxidant in industrial food and drugs.
