    Oyster mushroom [_Pleurotus ostreatus_ var. _sajor caju_ (Fr.) Singer] cultivation can play an important role in managing organic waste. It can be cultivated on a wide rang of substrates containing lignin and cellulose. Oyster mushroom was grown on five substrates: Rise straw (Oryza sativa L. var. Alikazemi), Rise straw + Oilseed Rape straw (Brassica napus var. Hyola 401) (75:25 dw /dw), Rise straw + Oilseed Rape straw (50:50 dw /dw), Rise straw + Oilseed Rape straw (25:75 dw /dw) and Oilseed Rape straw alone. Oilseed Rape straw alone and Rise straw + Oilseed Rape straw (25:75 dw /dw) were best for fruit body production of P. ostreatus. Time to fruiting for P. ostreatus was also shorter on Oilseed Rape straw. Protein content of the fruit bodies obtained from Oilseed Rape straw was higher than those from other substrates. Using Oilseed Rape straw as a substrate appears to be suitable for oyster mushroom production

    The least squared, the major axis and the reduced major axis criterion are used to deduce a statistical relation between magnitude, mbLg, and intensity, I, for the earthquakes-in southeastern United States. Based on a catalog of 162 events during 1833 to 1987, with magnitudes between 1.1 and 6.9 and intensities between II and X, it is shown that the reduced major axis criterion produces: mbLg = (0.656 ± 0.058)*I + (0.402 ± 0.178), which is the best predictor equation of magnitude for the upper range of the observed intensities. The predictor equations based on the least squared and major axis criterion are: mbLg = (0.441 ± 0.038)*I + (1.359 ± 0.176) and mbLg = (0,544 ± 0.047)*I + (0.898 ± 0.424), respectively; the least squared equation is a better predictor for the lower range of the observations and the major axis equation yields predictions which are between the predictions from the other two equations. In mid-range of the observed data all three equations predict nearly the same results. A set of three similar equations are found between intensity, I, and magnitude mbLg. The effects of various conversion methods on values of a and b in the frequency-magnitude equation log N= a + b*mbLg and values of a\u27 and b\u27 in the frequency-intensity relation log N= a\u27 + b\u27*I are negligible. Three new catalogs, with 2245 events in each were formed; in the new catalogs if the intensity or the magnitude of an event was missing it was estimated based on the above equations; then, the least squared technique was used to calculate the coefficients a, b, a\u27, and b\u27; the unnormalized values of the coefficients are: a = 4.105 ± 0.144, b = -0.591 ± 0.035, a\u27 = 3.941 ± 0.199, and b\u27 = -0.400 ± 0.033, respectively

    Summary. The statistical capability of the mb :Ms, discriminant for the discrimination of earthquake and explosion populations is examined by application of discriminant functions to a group of 83 explosions and 72 earthquakes in Eurasia. Equations are derived for the probability that an event is an earthquake or an explosion. The positive sign of DIS in the decision index equation, DIS, = 34.3383 - 11.9569 mbi, + 7.1 161 Msi, indicates that the event i is an earthquake. Its negative sign indicates that event i is an explosion. The probability of correct classification for an event, Pi, is reiated to its DISi, value, by Pi = [l t exp (DISi,)]-1, where a large, positive DIS indicates a high probability that an event is an earthquake and a large, negative DIS indicates a high probability that an event is an explosion. The discrimination line Ms = 1.680 mb ~ 4.825, or rnb = 0.595 Ms + 2.872 very successfully separates the explosion population from the earthquake population. The points on this line have an equal chance of being an earthquake or an explosion; moreover, for any event, the distance parallel to the Ms,-axis from the point representing that event in the mb:Ms, plane to this line is a measure of the probability for the correct classification of that event

    Fault Movements and Tectonics of Eastern Iran: Boundaries of the Lut Plate

    Summary. From 1977 March 21 to 1981 July 28, about 15 earthquakes with Ms ≥6.0 and many earthquakes with Ms≥4.5 have occurred in Iran. The upsurge of seismic activity started following the Khorqu earthquake of 1977 March 21, M,=7.0, south-east of the Fars folded series of Zagros. This shock had a thrust focal mechanism solution indicating the general northward movement of the Arabian plate with respect to the Iranian landmass. It was followed by six major damaging earthquakes in eastern Iran. The earthquakes are associated with extensive faulting which surrounds the Lut plate. (1) The Zarand earthquake of 1977 December, Ms=5.8, was associated with about 20 km of fault trace, severe mass wasting and about 20cm of right lateral movement. (2) The Tabas earthquake of 1978 September, Ms=7.7, with about 75 km of multiple thrust faulting and a maximum vertical displacement of 35cm. (3) The Kurizan earthquake of 1979 November, Ms=6.0, with more than 17 km of strike-slip fault trace and a maximum right-lateral displacement of 90cm and a vertical displacement of 60cm. (4) The Koli earthquake of 1979 November, Ms=7.1, with at least 65 km of fault trace and a maximum left-lateral displacement of 255 cm and a vertical displacement of 380cm. (5) Golbaf earthquakes of 1981 June, Ms=6.0 with at least 16 km of observed fault trace and a maximum vertical displacement of 15 cm. (6) The Chaharfarsang-Sirch earthquake of 1981 July, Ms=7.1, with about 70 km of discontinuous fault trace and 20cm of right-lateral motion and 15 cm of vertical motion. Portable networks of seismographic stations were deployed following each event. Results of aftershock studies are compared with field observations. The observed faults and aftershock zones appear to mark the broad deformational boundaries of the Lut plate

    Entrance Capacity of an Automated Highway System

    This paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing headways (produced in a separate analysis), the most promising concept utilizes platoons both on the highway and on on-ramps. However, it is unclear whether comparable capacity can be achieved on exit, when vehicles must be decoupled from their platoons, and whether it is safe for vehicles to enter the highway in closely spaced platoons. The analytical evaluation indicates that entrance/exit spacing on the order of one per 2 km or closer would be required to support highways with total capacity on the order of 20,000 vehicles per hour. Most likely, this would be achieved most efficiently if separate dedicated entrances are provided for automated vehicles, to minimize weaving on manual lanes

    Objective: The present study aimed to investigate the influence of gender differences in time perception in time perception in relation with number processing. Methods: fifty-six volunteer undergraduate female and male students of the University of Tabriz participated in the study. Numbers 1،2،8،9 were projected to all subjects in two duration of short time (300،400،500 millisecond) and long time (1000،1100،1200 ms) via a computerized time reproduction task. Subjects were asked to reproduce duration time of number. Three-factor ANOVA with repeated measures was used to analyze data. Results: Results revealed that the duration of short duration was overestimated, whereas the long durations were underestimated. Numbers affected time perception. The accuracy of time perception depended on the length of the duration and number. Reproduction of short duration was more inaccurate than long duration. In short duration, women had significantly accurate estimation in compare with men. Vice versa, men have exact estimate in long time in compare with women. But the differences between men and women were not salient like short duration. Conclusion: These findings indicate an interaction effect of gender and number processing on time perception. Results confirm existing evidence for gender differences in cognitive processing. In refers difference in time perception in relation with numbers in males and females

    This project is trying to investigate water contamination after use in ponds. For this aquaculture status, physical and chemical water properties, microbial pollutants and heavy metals levels in the some of trout ponds effluent in East Azerbaijan province were evaluated in 2007 to 2009. The information of groundwater and climate conditions in ten years, Drilling and wells piezometric Information, in local wells are reviewed. According to data obtained from analysis of water samples in the output pools range studied concentrations(term mg/l) some parameters are as follows:(BOD: 1.9-3.2), (COD: 3.4-34.1), (TSS: 26.6-42.7), (N-NO_2:0.003-.136),(P-Po4:0.0170.067), (pH:7.75-8.28). Electrical conductivity (500 ±2 to 1129±144 term µm/cm) in the effluent ponds. Based on the results of we can say that between input and effluent ponds in the review of all factors as chlorine, sulfate, sodium, potassium, total nitrogen, soluble phosphorus, total phosphorus, calcium, total hardness, magnesium, alkalinity and silica significant changes not be observed. Review of water analysis data to some factors (such as: water temperature, EC, pH, NO_2, CO_2, HCO_3, CO_3, DO, COD, BOD) and compare this data with the authorities standard confirmed that the All factors mentioned in effluent is allowed now. In terms of microbial contamination and heavy metals (Zn, Cu, Ca, Pb, Fe, Cr) is no pollution. Appropriate strategies for removing suspended materials must to use. We can use Watershed Management solutions to inject output water to the underground table. Should be noted status change (eg change in flow rate, an unusual increase in temperature, fish density increasing, reducing food quality, lack of appropriate management actions and ...) may reduce the effluent quality and the ability of injection water underground to lose. In this case, measures must be for wastewater treatment and improve the quality ponder

    Introduction The current study determined the level and trends associated with the incidence, death and disability rates for bladder cancer and its attributable risk factors in 204 countries and territories, from 1990 to 2019, by age, sex and sociodemographic index (SDI; a composite measure of sociodemographic factors). Methods Various data sources from different countries, including vital registration and cancer registries were used to generate estimates. Mortality data and incidence data transformed to mortality estimates using the mortality to incidence ratio (MIR) were used in a cause of death ensemble model to estimate mortality. Mortality estimates were divided by the MIR to produce incidence estimates. Prevalence was calculated using incidence and MIR-based survival estimates. Age-specific mortality and standardised life expectancy were used to estimate years of life lost (YLLs). Prevalence was multiplied by disability weights to estimate years lived with disability (YLDs), while disability-adjusted life years (DALYs) are the sum of the YLLs and YLDs. All estimates were presented as counts and age-standardised rates per 100 000 population. Results Globally, there were 524 000 bladder cancer incident cases (95% uncertainty interval 476 000 to 569 000) and 229 000 bladder cancer deaths (211 000 to 243 000) in 2019. Age-standardised death rate decreased by 15.7% (8.6 to 21.0), during the period 1990–2019. Bladder cancer accounted for 4.39 million (4.09 to 4.70) DALYs in 2019, and the age-standardised DALY rate decreased significantly by 18.6% (11.2 to 24.3) during the period 1990–2019. In 2019, Monaco had the highest age-standardised incidence rate (31.9 cases (23.3 to 56.9) per 100 000), while Lebanon had the highest age-standardised death rate (10.4 (8.1 to 13.7)). Cabo Verde had the highest increase in age-standardised incidence (284.2% (214.1 to 362.8)) and death rates (190.3% (139.3 to 251.1)) between 1990 and 2019. In 2019, the global age-standardised incidence and death rates were higher among males than females, across all age groups and peaked in the 95+ age group. Globally, 36.8% (28.5 to 44.0) of bladder cancer DALYs were attributable to smoking, more so in males than females (43.7% (34.0 to 51.8) vs 15.2% (10.9 to 19.4)). In addition, 9.1% (1.9 to 19.6) of the DALYs were attributable to elevated fasting plasma glucose (FPG) (males 9.3% (1.6 to 20.9); females 8.4% (1.6 to 19.1)). Conclusions There was considerable variation in the burden of bladder cancer between countries during the period 1990–2019. Although there was a clear global decrease in the age-standardised death, and DALY rates, some countries experienced an increase in these rates. National policy makers should learn from these differences, and allocate resources for preventative measures, based on their country-specific estimates. In addition, smoking and elevated FPG play an important role in the burden of bladder cancer and need to be addressed with prevention programmes.publishedVersio

    Opium use and risk of bladder cancer : A multi-centre case-referent study in Iran

    Get PDF
    Background: Bladder cancer (BC) is the 10th most common type of cancer worldwide and the fourth most common type of cancer in Iran. Opium use is considered as one of the risk factors for BC. We aim to assess the association between various parameters of opium use, which in Iran is mainly ingested or smoked in various forms, and the risk of BC. Method: In this multi-centre case-referent study in Iran, 717 BC cases and 3477 referents were recruited to the study from May 2017 until July 2020. Detailed histories of opium use (duration, amount, frequency) and potential confounders were collected by trained interviewers. Multivariable unconditional logistic regression models were used to measure adjusted odds ratio (OR) and 95% confidence intervals (CI). The ORs were adjusted for age, gender, place of residence and pack-years of cigarette smoking. Results: Regular opium consumption was associated with an increased risk of BC (OR 3.5, 95% CI: 2.8, 4.3) compared with subjects who never used opium. Compared with continuous users, the risk decreased to one-Third for those who stopped opium more than 10 years ago. The adjusted OR for those who used both crude opium (teriak) and opium juice was 7.4 (95% CI: 4.1, 13.3). There was a joint effect of opium and tobacco (OR for users of both opium and tobacco 7.7, 95% CI: 6.0, 9.7). Conclusions: Regular opium use is associated with an approximately 4-fold risk for BC. The OR decreases along with the increasing time since stopping opium use.publishedVersionPeer reviewe
