Identifying the constraining factors of production and yield gap is very important. Therefore; this research was performed to identify the production constraining factors of local rice cultivars. All management practices from nursery preparation to harvesting stages for 100 paddy fields of local rice cultivars were recorded through field studies, in Sari, from 2015-2016. In the CPA, the actual and calculated potential yield were 4495 and 5703 kg/ha, respectively and the gap was 1221 kg/ha. The yield gap caused by number of top-dressing variables was 324 kg/ha, equal to 27% of the total yield gap. The yield gap related to previous year of legumes cultivation was 218 kg ha-1, equal to 18% of the total yield variation. Among the 10 variables entered in the CPA model, the effects of top-dress fertilizer application and its application frequency and foliar application were remarkable, which could compensate a significant part of the yield gap (444 kg/ha, 37% of total) in the farmers’ fields by managing these variables. According to boundary line analysis (BLA) finding, actual yield mean on the basis of optimal limit related to 12 variables under study was 5369 kg/ha, with 881 kg/ha yield gap . Mean relative yield and relative yield gap for 12 variables (transplanting date, seedling age, number of seedlings per hill, planting density, nitrogen and phosphorous per hectare, nitrogen before transplanting, harvesting date, lodging problem, pest problem, diseases problem and weeds problem) were 83.64 and 16.35 kg/ha, respectively. Based on the finding, it can be stated that the model precision is appropriate and can be applied for both estimation of the quantity of yield gap and determining the portion of each restricting yield variables.

Dēnkard (Acts of the religion), written in Pahlavi, is a summary of 10th-century knowledge of the Mazdean religion and is described by Jean de Menasce on the title page of his translation as a ‘Mazdean encyclopedia.’ The Dēnkard VI (Book VI of the Dēnkard) is representative of late antique and early medieval Zoroastrian ethical ideas. This article analyzes Book VI of the Dēnkard based on modern moral philosophy and introduces it as a candidate for early consequentialism and capitalism. The first generation of Iranian studies scholars in the late 19th and early 20th centuries such as Buch, Darmesteter, and Menant were aware of these concepts and even explained some of them, but the next generation did not take them seriously. This article also analyzes paymān (the ‘right measure’), that is the ancient Iranian ‘golden mean,’ in Book VI of the Dēnkard and shows the similarities and differences between paymān and the Aristotelian ‘golden mean.’ Probably, due to the biblical tradition in the interpretation of ancient religious texts or the anti-utilitarianism and anti-capitalism atmosphere in the second half of the 20th century, many scholars like Shaked inclined to the view that paymān is the main ethical principle of the Dēnkard VI and neglected its consequentialist and capitalist concepts.

The lack of Quranic approaches in the production of Quran-based humanities is still felt, despite the predominance of the philosophical approach in critical approaches to modern humanities, which has become very common in the Islamic world and in Iran for several decades. It seems that the capacity of the method of thematic exegesis (al-Tafsīr al-mawdū'ī, Arabic: التفسیر الموضوعیّ) in this regard, can be used to bring the Holy Quran into the field of humanities. Thematic exegesis, according to whether its subject is inside or outside the Qur'an, has several functions in criticizing the structure of modern knowledge and scientific research, as well as the production of Islamic humanities. It is possible to make use of thematic exegesis of the inside of the Holy Book of Quran in order to “fundamental criticism” of the general fundamentals of humanities -the fundamentals of epistemology, axiology, ontology and anthropology- and it is also possible to use thematic exegesis for constructing and producing foundation of humanities obtained from the Holy Quran. It is used by thematic interpretation exegesis of the outside of the Holy Book of Quran -such as Shahīd (martyr) Sadr’s interrogational approach- to answer the problems of humanities and this process faces challenges such as the complexity and multiplicity of the “subject” of the humanities that exist in modern terminology of this field. It can be used in order to solve this issue in some cases to know the process of the change of the components of the modern of the conceptual history’s approach and also by analyzing the issue into several components can be shown that the components are not necessarily a product of the modern era and can be followed up in the Holy Quran and can be found up in the Holy Quran. The perspective of the Holy Quran, after that, regarding the modern subject in the desired field by the “combining” of the results obtained based on the thematic interpretation.

This study was conducted during summer and winter of 2018- 2019 in the agricultural research field of Shahid Chamran University. Experimental design was split- plot based on RCBD with three replications. The main plot was the type of agricultural system in three levels including conventional (Conv), organic (Org) and sustainable (Sust) (integrated between Conv and Org) and sup- plot was the type of pre- cultivated crop in sequence with wheat including cultivation of mung bean (M- W), corn (C- W), sesame (S- W) and fallow (F- W). Yield quantity (yield and its component) and quality (grain protein), an estimate of photosynthesis matter transfer index of wheat and soil organic carbon (SOC) after one double-cropping were measured. The result showed that the highest (545.04 g/m2) and the lowest (409.28 g/m2) seed yields were obtained in Conv and Org respectively. In contract, with the changing type of system from Conv to Org, grain protein was increased significantly (from 8.3 to 9.6 %). In addition, the highest (535.47 g/m2) yield of wheat was obtained from M- W double cropping. On the other hands the highest remobilization and current photosynthesis matter were obtained in the organic agricultural system with M- W and conventional with M- W double cropping. The situation of SOC showed that the highest (33.18 mg/g) SOC was obtained in the organic agricultural system with C- W double cropping. The reason for improving SOC in the organic and sustainable agricultural system was application of organic matter (compost and vermicompost) and crop residue management. Totally, from the crop ecology point of view, sustainable agricultural method with a sequence of M- W was the most desirable system.

Medicinal plants contain active ingredients in one or some of their organs. Squalene is one of the active ingredients that prevent heart attacks and cardiovascular diseases and protect the body from some cancers. The aim of the present study was to investigate the presence of squalene in a number of medicinal plants. In this experiment, the plant oils were extracted and measured using Bligh & Dyer with minor changes. TLC (thin layer chromatography) was used to identify squalene. Comparison of TLC of standard squalene with TLC of the investigated medicinal plant samples showed that Caryophillium aromaticus, Descurainia sophia, Portulaca Oleracea, Papaver somniferum and Nigella Sativa contained squalene. Although the percentage of Papaver somniferum and Nigella Sativa seed oil was higher than other medicinal plants, the squalane spot of clove plant had a higher intensity of color and this indicates a higher concentration of squalene in this plant.

Optimizing the placement of wells is a crucial step in field development as it directly impacts production and cost. Inappropriate well placement can lead to decreased production and higher costs due to the expensive drilling process. Vertical well placement focuses on optimizing wellhead coordinates (x and y parameters), while horizontal and deviated wells require considering the depth of the wells (z parameter) along with operational limitations. This research presents an automatic framework that utilizes the particle swarm optimization algorithm to optimize the location of horizontal wells, taking into account drilling limitations. The objective function used is the net present value (NPV). This framework defines the number of particle swarm optimization variables based on operational constraints and well geometry. The algorithm randomly selects parameter values and applies the optimization procedure while considering specific constraints until the stop criteria are met. The framework successfully optimized the x, y, z, LP (Landing point), and KOP (Kick of Point) parameters in two heterogeneous synthetic models and a benchmark model (PUNQ_S3). On average, the net present value increased by 22% in all models, with greater heterogeneity resulting in a higher increase compared to homogeneous models.

In this study, weather conditions such as air humidity, temperature air, and wind speed were investigated in relation to wind turbine efficiency with the approach of an exergy study. In this study, the wind speed has been investigated in two different climatic regions of Iran with an approximate distance of 1200 km, in the names of Ardabil and Marvast. The amount of wind density of Ardabil is equal to 66 (kW/m2) and Marvast is equal to 123 (kW/m2). Power production using a 10 (Kw) wind turbine in the Ardabil region is 2.3 (MWh) and in the Marvast region is 3.2 (MWh) per year. The highest wind turbine exergy efficiency is 0.48 in the Ardabil region, and the highest exergy efficiency in the Marvast region is 0.18. The amount of reduction of CO2 gas production, using wind turbines in comparison to gas and diesel power plants in Ardabil, are 1.1 and 2.1 tons and in Marvast are 1.5 and 2.9 tons per year. This reduction in CO2 greenhouse gas per year is equal to using a forest region of 1000 (m2) to 3000 (m2). The use of wind turbines reduces the fuel consumption of diesel power plants in the Ardabil region for the amount of 797.4 liters and in the Marvast region for the amount of 1244 liters of diesel per year. According to this review, it can be concluded that in addition to wind speed, air humidity plays a significant role in the selection, installation, and commissioning of wind turbines in the region. According to this survey, it can be seen that in the Ardabil region, the wind speed of the wind turbine has a higher exergy efficiency than in the Marvast region, and it can be concluded that the wind turbine has performed better in the Ardabil region.
