Die Leitideen der Diagnose und individuellen Förderung sind in den vergangenen Jahren nicht nur in den Blickpunkt der bildungswissenschaftlichen und fachdidaktischen Forschung gerückt, sondern haben bereits Eingang in einige lehrerbildende Studiengänge genommen. Ein Beispiel hierfür stellt das Projekt dortMINT dar, das im Rahmen der Exzellenzinitiative ” MINT-Lehrerbildung“ von der Deutsche Tel...
BACKGROUND Developing algal industries in saline-alkali areas is necessary. However, suitable strains and optimal production conditions must be studied before widespread commercial use. OBJECTIVES The effects of light, temperature, KNO3, and CO(NH2)2 on beta-carotene and biomass accumulation were compared and evaluated in order to provide scientific guidance for commercial algal production in...
The seemingly trivial moving boundary problem of the crystallization of a solid phase from a cooled wall comes under the rubric of the so-called Stefan problems describing a wide range of physical processes. Their rich nonlinear behavior has attracted substantial scientific interest and their ubiquity in fields ranging from metallurgy to geophysics stimulates developing new mathematical approac...
It is very important that tannery wastes in the form of sludge are managed in an environmentally sound manner. This study focused on the heavy metal characterization and the influence of changing the physico-chemical properties of the medium throughout the composting on the concentrations, bioavailability or chemical forms of Cr, Cu, Zn, Pb and Cd in tannery sludge. The physical and chemical pr...
مقابله با آثار مخرب تنش شوری که به طور پیش رونده منابع آبی و خاکی مناسب برای پرورش گیاهان را محدود نموده، از طریق ارتقای سطح تحمل بذر و گیاهچه میسر است. در پژوهش حاضر، تأثیر پرایمینگ به صورت ترکیب های تیماری na2sio3 و kno3 در زمان های 3، 6، 9 و 12 ساعت، بر پاسخ رقم همدانی بذر یونجه، به تنش شوری (200 میلی مولار) بررسی گردید. شوری سبب افت اغلب شاخص های جوانه زنی و رشد بذور و گیاهچه گردید، در حالی...
The present study examined the effects of different nitrogen (NH4NO3) and potassium (KNO3) fertilization levels in combination with a nitrogen-fixing, plant growth-promoting rhizobacteria (PGPR) inoculation on carbohydrate (CHO), amino acid content, nutrient concentrations (N, P, K) spears root system asparagus plants. No significant differences were indicated between treatments regarding N, K ...

KNO3 was used as the phase change material (PCM), but its thermal conductivity is too low to transfer heat between the PCM and conduction oil efficiently. In this thesis, on the basis of the previous studies (Yong Li, 2015), the solar power generation efficiency is enhanced with high temperature interval (280°C—400°C), and the new composite which are composed by the SiC honeycomb (SCH) frame an...
This paper examines the implications of tax evasion for "scal competition and tax harmonization policies in an economic union. First, for symmetric countries, it proves that the equilibrium values of the tax and audit rates are less than optimal. Tax harmonization alone will also lead to a less than optimal audit rate. Second, for asymmetric countries, the paper shows that integration may turn ...
