Field study and numerical simulation of developing red tide in the northern Strait of Hormuz

The catastrophic event of red tide has happened in the Strait of Hormuz, the Persian Gulf and Gulf of Oman from late summer 2008 to spring 2009. With its devastating effects, the phenomenon shocked all the countries located in the margin of the Persian Gulf and the Gulf of Oman and caused considerable losses to fishery industries, tourism, and tourist and trade economy of the region. In the maritime cruise carried out by the Persian Gulf and Gulf of Oman Ecological Research Institute, field data, including temperature, salinity, chlorophyll-a, dissolved oxygen and algal density were obtained for this research. Satellite information was received from MODIS and MERIS and SeaWiFS sensors. Temperature and surface chlorophyll images were obtained and compared with the field data and data of PROBE model. The results obtained from the present research indicated that with the occurrence of harmful algal blooms (HAB), the Chlorophyll-a and the dissolved oxygen contents increased in the surface water. Maximum algal density was seen in the northern coasts of the Strait of Hormuz. Less concentration of algal density was detected in deep and surface offshore water. Our results show that the occurred algal bloom was the result of seawater temperature drop, water circulation and the adverse environmental pollutions caused by industrial and urban sewages entering the coastal waters in this region of the Persian Gulf ,This red tide phenomenon was started in the Strait of Hormuz and eventually covered about 140,000 km2 of the Persian Gulf and total area of Strait of Hormuz and it survived for 10 months which is a record amongst the occurred algal blooms across the world. Temperature and chlorophyll satellite images were proportionate to the measured values obtained by the field method. This indicates that satellite measurements have acceptable precisions and they can be used in sea monitoring and modeling.

Labroidaes dimidiatus (Valenciennes, 1839)

Labroides dimidiatus, is one of several species of cleaner wrasses found on coral reefs from Eastern Africa and the Red Sea to French Polynesia, for the first time from Iran (Persian Gulf, Kish Island). Like other cleaner wrasses, it eats parasites and dead tissue off larger fishes’ skin in a mutualistic relationship that provides food and protection for the wrasse, and considerable health benefits for the other fishes. Some fish mimic cleaner wrasses. For example, a species of blenny called Aspidontus taeniatus has evolved the same behavior to tear small pieces of flesh from bigger fish. Cleaner wrasses are usually found at cleaning stations. Cleaning stations are occupied by different units of cleaner wrasses, such as a group of youths, a pair of adults, or a group of females accompanied by a dominant male. When visitors come near the cleaning stations, the cleaner wrasses greet the visitors by performing a dance-like motion in which they move their rear up and down. The visitors are referred to as "clients". Blue streak cleaner wrasses clean to consume ectoparasites on client fish for food. The bigger fish recognise them as cleaner fish because they have a lateral stripe along the length of their bodies and by their movement patterns.

Plotosus lineatus (Thunberg, 1787)

The Striped Catfish can be recognized by its striped coloration, barbels around the mouth, and its body shape which tapers to a point posteriorly. Small juveniles are black and large adults may be less distinctly striped. Plotosus lineatus can reach a maximum length of 32 cm (13 in) and about 40cm in Persian Gulf. The body is brown with cream-colored or white longitudinal bands. The most striking feature of this species is in the fins; in fact the second dorsal, caudal and anal are fused together as in eels. In the rest of the body is quite similar to a freshwater catfish: the mouth is surrounded by four pairs of barbells, four on the upper jaw and four on the lower jaw. The first dorsal and each of the pectoral fins have a highly venomous spine. They may even be fatal. Juveniles of P. lineatus form dense ball-shaped schools of about 100 fish, while adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day. Adult P. lineatus search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish. Striped eel catfish is an oviparous fish; this species has demersal eggs and planktonic larvae. This species has evolved long ampullary canals in its electrosensory organs.

Torpedo sinuspersici Olfers, 1831

Electric rays, thought to be the most primitive of the skates and rays, have stout tails but have rather expansive disc. This group is distinguished by the presence of powerful electric organs, derived from branchial muscles in head region. Torpedo sinuspersici found inshore in sandy bottoms, and well offshore from the surf zone down to 200 m. Also on or near coral reefs (like Kish Island in Persian Gulf). Common in shallow sandy areas. Occasionally hooked by anglers, more often seen by divers; can deliver a strong shock. Flesh is edible. T. sinuspersici can survive for hours after being stranded on the beach. Little is known of the life history of the Gulf torpedo. It is a sluggish predator of bony fishes. At night it actively hunts for food, sculling slowly through the water about a meter above the bottom; during the day it usually rests on the bottom and opportunistically ambushes unwary prey. It uses its broad pectoral fins to envelop the target fish before delivering an electric shock to stun it. Usually solitary, they may form groups during the mating season. Reproduction is a placental viviparous, with the developing embryos initially surviving on their yolk sacs, and then on enriched uterine fluid produced by the mother. Litters of 9-22 young are birthed in the summer. Newborns measure about 10 cm wide; males mature at a disc width of 39 cm and females at 45 cm.

Chrysiptera unimaculata Cuvier, 1830

Chrysiptera unimaculata, an algivorous species also living on the coral reef flat and being territorial but not considered as a strict farmer in this location. Maximum length is 8 cm in Persian Gulf. It is living in close association with macrophytes. Adults are found solitarily or in small groups among coastal algal reefs, rubble or over open beach-rock of reef flats exposed to moderate surge and feeds mainly on benthic algae. C. unimaculata is oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.

Koumansetta hectori Smith, 1957

Many aquarists know this fish as Ambylgobius hectori but accepted name is actually Koumansetta hectori. K. hectori, Hector's goby, is a species of goby native to the Indian Ocean (including the Red Sea), first record from Persian Gulf (Kish Island, Iran) to the islands of Micronesia in the western Pacific Ocean. It can be found on sheltered coral reefs at depths of from 3 to 30 meters (though usually between 5 to 20 meters). This species reaches a length of 8.5 centimeters (3.3 in) SL. This attractive little fish measures only 2” at maturity and spends its time hovering over rocks and substrates out in the open water column. Known for their bold yellow stripes, peaceful disposition, the diminutive Hector’s Goby is a nano reef favorite. It can also be found in the aquarium trade.

Pempheris vanicolensis (Cuvier, 1831)

Pempheris vanicolensis has reported for the first time from Persian Gulf (Kish Island). Various aspects of the biology of P. vanicolensis Cuvier & Valenciennes, a recent Lessepsian (Suez Canal) immigrant into the Mediterranean, are given. Red Sea and Mediterranean populations were compared, and the results indicate that the spawning season is shortened in the Mediterranean, continuing from April to September, as opposed to year-round in the Red Sea. Descriptions of a ripe ovary and post-larva from the Mediterranean are given. Individuals reach a mean size of 10.8 cm in their first year, and 14.4 cm in the second year. Little change has occurred in the diet of the immigrant population, and both populations feed nocturnally, chiefly on larval and adult stages of planktonic crustaceans. Direct underwater observations on the diurnal behavior of the species show that the fish leave their daytime cave shelter at sunset, congregate at a nearby site and then migrate inshore and disperse into small groups to feed. Before dawn, they reassemble at the cave's entrance, and finally enter it at sunrise, after the school has built up. Observations on Persian Gulf sweepers show that the fish are segregated into size groups, ranging 15–18 cm adults at depths of 3 m.

Investigation on water and sediment quality variation from coast to off shore and its relation to bent hoses biodiversity: case study Bandar tahery

This paper deals with the qualification of water and sediment particularly those of benthos, as well as their interaction results, through careful laboratory researches within 24 experimental sites around the bank of Bandar Taheri, Persian Gulf water of Iranian borders, under 13th phase south Pars project. Samples were carried to the laboratories and careful experimental tests such as physical chemical, heavy metal, nitrate ammoniac, toc and other biologic tests including various type of benthos count were performed. Data gained through Shanon and Dankan statistical analyses were also studied to determine the water, sediment and pollution rate. Resulted information would classify the area as less polluted area which is rather away from critical environmental zone, another word the area could be liable to change to an undesired one while the density rates of principal metals follows the Fe>Mn>Zn>Cu>Pb>Cd>N pattern.

Sequence stratigraphy and sea-level history of Kangan formation in south pars field

Dehram group includes Faraghan, Dalan and Kangan formations. Kangan formation ages lower terias. That is one of the important reservoir rocks of southern Iran and Persian Gulf. In this research Kangan formation is studied in two A and B wells. Based on 75 studies on thin section, four carbonate litho acies association A, B, C, D with 12 subfacies are identified. A lithofacies association includes 4 subfacies: A1, A2, A3 and A4. B lithofacies association consists of 3 subfacies: B1, B2 and B3. C lithofacies association consists of 3 subfacies: C1, C2, C3 and D lithofacies association includes 2 subfacies: D1 and D2. On the base of studies lithofacies association of Kangan formations are formed in 3 environments of: Tidal Flat, Lagoon and Barrier Shore Complex in a Carbonated Platform Ramp type. Diagenetic processes have effected this formation. The most important Diagenetic processes are: Cementation, Anhydritization, Micrization, Neomorphism, Bioturbation, Dissolution, Compaction, Dolomitization and Porosity. Sequence staratigraphy studies were performed base on the vertical and horizontal relationship of lithofacies association and well logging in gamma ray and sonic type that causes the identification of two sedimentary sequences: First sedimentary sequence includes: Transgressive System Tract (TST) and High Stand System Tract (HST). The lower boundary of this sequence is in Sequence Boundary 1 (SB1) which shows unconformities of Dalan and Kangan that are Permian-terias unconformities. The upper boundary is in Sequence Boundary 2 (SB2) type that is identified by carbonate facies associated by anhydrite nodular. Second sedimentary sequence includes: TST and HST. Lower and upper boundaries of these sequences are both in SB2 type. The lower and upper boundary is made of carbonate facies with anhydrite nodular.

Un pasaje controvertido en los Annales de Eutiquio de Alejandría. El ataque judío a la ciudad de Tiro

En los Annales compuestos por el patriarca Eutiquio de Alejandría encontramos algunos pasajes originales, que no están presentes en otras fuentes, por lo que muchos estudiosos han descartado su verosimilitud. No obstante, hay que tener muy presente el contexto h istórico en el que este personaje vivió, en contacto tanto con musulmanes como con judíos. Un ejemplo de esto es el relato que hace del ataque de los judíos contra la ciudad fenicia de Tiro durante la guerra romano-persa (603-628), calificado como fantasioso. Sin embargo, cambia la perspectiva cuando se lo relaciona con textos apocalípticos de la tradición hebrea.

Flixweed vs. Polyethylene Glycol in the Treatment of Childhood Functional Constipation: A Randomized Clinical Trial

Background: Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation. Objectives: To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation and to assess its efficacy and side effects. Patients and Methods: 120 patients aged 2 - 12 years with constipation for at least 3 months were included in an 8 weeks lasting randomized controlled trial within two parallel-groups. Children received either PEG, 0.4 g/kg/day, or D. sophia seeds, 2 grams (for children aged 2 - 4 years) and 3 grams (for those aged > 4 years) per day. Results: A total of 109 patients completed the study (56 in D. sophia and 53 in PEG group). At the end of the study, 36 (64.3%) patients in D. sophia group and 29 (54.7%) in PEG group were out of Rome III criteria (P = 0.205). Median weekly stool frequency in 0, 1, 2, 3 weeks of the treatment was found to be 2, 5, 5, 5 in D. sophia and 3, 4, 4, 5 in PEG group (P = 0.139, 0.076, 0.844, 0.294), respectively. The number of patients who suffered flatulence was less (5, 8.9%) in D. sophia group as compared to PEG group (6, 11.3%) at the end of the trial (P = 0.461). D. sophia taste was less tolerated. Conclusions: D. sophia is introduced as a cheap and available medication which can be applied as a safe alternative to conventional PEG in the management of pediatric chronic functional constipation.

Prevalence of preterm labor in Iran: A systematic review and meta-analysis

Background: Preterm labor, which defines as live-birth delivery before 37 weeks of gestation is a main determinant of neonatal morbidity and mortality around the world. Objective: The aim of this study was to determine the prevalence of preterm labor in Iran by a meta-analysis study, to be as a final measure for policy makers in this field. Materials and Methods: In this meta-analysis, the databases of Thomson database (Web of Knowledge), PubMed/Medline, Science Direct, Scopus, Google Scholar, Iranmedex, Scientific Information Database (SID), Magiran, and Medlib were searched for articles in English and Persian language published between 1995 and 2014. Among the studies with regard to the inclusion and exclusion criteria, 14 studies (out of 1370 publications) were selected. Data were analyzed by using Stata software version 11. The heterogeneity of reported prevalence among studies was evaluated by the Chi-square based Q test and I2 statistics. Results: The results of Chi-square based on Q test and I2 statistics revealed severe heterogeneity (Q=2505.12, p-value < 0.001 and I2= 99.5%) and consequently, the random effect model was used for the meta-analysis. Based on the random effect model, the overall estimated prevalence of preterm in Iran was 9.2% (95% CI: 7.6 – 10.7). Conclusion: Present study summarized the results of previous studies and provided a comprehensive view about the preterm delivery in Iran. In order to achieve a more desirable level and its reduction in the coming years, identifying affecting factor and interventional and preventive actions seem necessary.

A study of culture specific items and translation strategies in Bahram Beyza'i’s play “Marionettes”

L'objectif de cette recherche est de fournir une analyse de la pièce de théâtre perse ''Marionettes'' de Bahrām Beyzā'ī (1963) ainsi que de sa traduction anglaise (1989) afin de comparer et de mettre en contraste les traits propres à la culture «Culture-specific items» (CSI) et des stratégies de traduction. Les formes problématiques pertinentes des différences culturelles seront étudiées et les procédés suggérés par Newmark (1988) seront examinés afin de déterminer dans quelle mesure ils sont pertinents dans la traduction des différences culturelles du perse à l'anglais. La pièce a été traduite par une équipe de traducteurs: Sujata G.Bhatt, Jacquelin Hoats, Imran A. Nyazee et Kamiar K. Oskouee. (Parvin Loloi et Glyn Pursglove 2002:66). Les oeuvres théâtrales de Beyzā'ī sont basées sur les traditions ainsi que sur le folklore iranien. L'auteur aborde la réalité sous une perspective philosophique. « (Un point de vue) enveloppé dans une cape de comparaisons complexes à tel point que nombre des personnages de son oeuvre errent entre des symboles de la mythologie et de l’histoire, ou sociaux» (M.R. Ghanoonparvar, John Green 1989, p.xxii notre traduction). La classification des éléments culturels de Newmark (1988) va comme suit: «Écologie, culture matérielle, culture sociale, organisations, coutumes / moeurs, gestes et habitudes» (Newmark 1988:95). La recherche mettra l’accent sur les procédés suggérés pour traduire les CSI ainsi que sur les stratégies de traduction selon Newmark. Ces procédés comprennent : «traduction littérale, transfert, équivalent culturel, neutralisation, équivalent fonctionnel, équivalent descriptif, synonymie, par le biais de la traduction, transposition, modulation, traduction reconnue, étiquette de traduction, compensation, analyse componentielle, réduction et expansion, paraphraser, distique, notes, additions, gloses» (Newmark 1988:81-93). L'objectif ici est de déterminer si les procédés suggérés sont applicables à la traduction des CSIs du perse à l'anglais, et quels sont les procédés les plus fréquemment utilisés par les traducteurs.
