Introduction: Oil is one of the primary commodities of all countries globally and is, in essence, the energy base of all that we know as transportation. Therefore, price fluctuations of derivatives, especially fuel and oil derivatives, are the policymakers’ main concerns because they can cause serious problems, such as inflation in commodity prices. Objective: The impact of fuel carriers’ prices on the consumer price index remains a subject of debate and research. This paper aims to develop a model to define the inflation regime in Iran and then investigate the impact of gasoline and diesel price on the total inflation rate. Method: In this study, using the central bank time series and available data on energy balance and World Bank data banks, a non-linear distributed online delay regression modeling is developed to analyze the relationship between fuel price and essential commodity inflation. Results: The results show that there is an impact of gasoline price on inflation. It does not have much effect in the long term, but diesel can somewhat influence raising prices, which can exacerbate poverty in the community that needs special attention. Conclusion: It was also found that diesel’s price is harmful to the economy because it can stimulate inflation in the long term. However, in the short term, diesel does not cause any significant inflation in the prices. While gasoline prices can have many short-term social effects, this paper suggests that the Iranian government control diesel fuel prices prevent long-term inflation in inflation and consumer price rate.

Abstract Background: This study aims to investigate the impacts of fuel price policies on the concentration of air pollutants emitted from the transport sector.Methods: Autoregressive distributed lag (ARDL) estimation models were used to investigate the impacts of gasoline and diesel prices along with the weather and economic variables on the following traffic-related pollutants: Carbon monoxide (CO), Nitrogen dioxide (NO2), and Particular matter 10 micrometers or less (PM10).Results: In the short term, one percent increase in gasoline prices leads to 0.02 and 0.012 percent decrease in the concentration of CO and PM10, respectively. In addition, in the short term, one percent increase in diesel prices leads to 0.008, 0.02, and 0.015 percent decrease in the concentration of CO, PM10, and NO2, respectively. Results demonstrate that one percent increase in gasoline prices leads to 0.011 and 0.02 percent increase in NO2 concentration in the short term and long term, respectively. Fuel prices had a greater impact on air pollutant concentration in the long term than in the short term. In the long term, one percent increase in diesel prices leads to 0.011, 0.024, and 0.029 percent decrease in the concentration of CO, NO2, and PM10, respectively.Conclusion: Although fuel price increases lead to a significant reduction in air pollution concentration, other factors related to weather conditions (wind speed, temperature, and rainfall) as well as economic activities have a greater impact on air pollution. Therefore, other policies such as improving fuel quality and technology along with other economic policies can be more effective.

Based on its advantages and providing a big part of total energy in the country, natural gas lies in a prominent place among other energy sources. Making cognition and accurate identification of practical elements on the volume of periodic (short and long) demands on natural gas can help us outline suitable plans and policies related to energy. By this view, practical items on natural gas demands had been evaluated. The ARDL pattern with distributed interruptions and ECM model was employed to investigate the function of demands on natural gas during the years from 1976 to 2013. The result proved all coefficients of variables in short and long periods. The natural gas price ratio confirms a contrary relation between natural gas demand and its price in the short term. This ratio in the long-term shows a direct connection between them. Related results to the electricity price ratio show that the electricity price variable has the most positive effect on natural gas demands . Related results show that natural gas's long-term price and income strain are more than short-term ones. Also, results show that natural gas in short periods is a non-strained and necessary commodity. Being non-strained in the short-term results in a lack of efficiency of price policies. So, releasing the price of natural gas can prevent unnecessary consumption of this valuable fuel. Price strain of natural gas in long spans proves that natural gas is a complete strain commodity. This fact is based on why there is some replacement for natural gas, such as electricity and gasoline, for long periods. The minus behind income strain shows that natural gas in the long-term is as low stuff. Intersecting the price of electricity in short and long-term investigations is positive and shows a substitutional relation between electricity and natural gas. The negative intersecting strain of price of kerosene shows that natural gas and kerosene in both the short and long-term are complementary. Also, the gasoline price ratio confirms the complementary relationship in the short-term and substitutional relation in the long-term between natural gas and gasoline.



Subject Fuel price liberalisation. Significance The liberalisation of Mexican fuel prices this month has seen a sharp increase in pump prices. In a televised address on January 5, President Enrique Pena Nieto said that his government would not reverse the price jump, despite protests throughout the country that have often become violent. Impacts Competition between distributors will take time to develop, precluding any short-term price reductions. The National Action Party (PAN) or the National Regeneration Movement (MORENA) may take the presidency in 2018. Uncertainty on whether prices may be artificially lowered by the next government may deter long-term investments in the fuel market.

Therefore, derivatives price fluctuations, especially those of fuel and oil derivatives, are the main concerns of the policymakers because they can cause serious problems, such as inflation in commodity prices. Objective: The impact of the price of fuel carriers on food price index remains a subject of debate and research. the aim of this paper is to develop a model to define the inflation regime in iran and then to estimate gasoline and diesel price impact in the inflation anount. Method: In this study, using the central bank time series and available data on energy balance and World Bank data banks a non-linear distributed online delay regression modeling is developed to analyze the relationship between fuel price and basic commodity inflation. Results: the results show that gasoline prices have an impact. In the long run, it doesn't have much in the way of prices, but diesel can be somewhat effective in raising prices, which can exacerbate poverty in the community that needs special attention. Conclusion: It was also found that the price of diesel is harmful to the economy because it can stimulate inflation in the long term. However, in the short term, diesel does not cause any significant inflation in the prices. While the price of gasoline can have many short term social effects, therefore, the Iranian government must control the price of diesel fuel to prevent long-term food price inflation.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.

Objectives School-age children with and without parent-reported listening difficulties (LiD) were compared on auditory processing, language, memory, and attention abilities. The objective was to extend what is known so far in the literature about children with LiD by using multiple measures and selective novel measures across the above areas. Design Twenty-six children who were reported by their parents as having LiD and 26 age-matched typically developing children completed clinical tests of auditory processing and multiple measures of language, attention, and memory. All children had normal-range pure-tone hearing thresholds bilaterally. Group differences were examined. Results In addition to significantly poorer speech-perception-in-noise scores, children with LiD had reduced speed and accuracy of word retrieval from long-term memory, poorer short-term memory, sentence recall, and inferencing ability. Statistically significant group differences were of moderate effect size; however, standard test scores of children with LiD were not clinically poor. No statistically significant group differences were observed in attention, working memory capacity, vocabulary, and nonverbal IQ. Conclusions Mild signal-to-noise ratio loss, as reflected by the group mean of children with LiD, supported the children's functional listening problems. In addition, children's relative weakness in select areas of language performance, short-term memory, and long-term memory lexical retrieval speed and accuracy added to previous research on evidence-based areas that need to be evaluated in children with LiD who almost always have heterogenous profiles. Importantly, the functional difficulties faced by children with LiD in relation to their test results indicated, to some extent, that commonly used assessments may not be adequately capturing the children's listening challenges.
