In the spirit of productive scientific discussion we would like to start by thanking Faltus and Storz [1] for their comments. We have studied them carefully and would like to add the following comments from our perspective: 1. Faltus and Storz were correct in stating that the German Embryo Protection Act (Embryonenschutzgesetz, ESchG) and the expansion of some of its points in the German Preimp...
Cities impact both local climate, through urban heat islands and global climate, because they are an area of heavy greenhouse gas release into the atmosphere due to heating, air conditioning and traffic. Including more vegetation into cities is a planning strategy having possible positive impacts for both concerns. Improving vegetation representation into urban models will allow us to address m...
Abstract Monoclinic TeB 4 O 8 was obtained in a Walker‐type multianvil apparatus at 10 GPa and 1273 K from TeO 2 B 3 . It crystallizes isotypically to the compounds An ( =Th, U) space group C 2/ c Z =4) with lattice parameters =15.6978(8) Å, b =4.2284(2) =7.4305(4) β =114.78(1)°, V =447.80(4) Å Further, it has been characterized via X‐ray diffraction experiments IR spectroscopy.
The study was based on saline soils with surface mineral layers impacted by the waste produced soda plant in Poland. activity of selected enzymes (catalase CAT, alkaline AlP, and acid phosphatase AcP), pH KCl, content clay, total organic carbon (TOC), nitrogen (TN), exchangeable bases (TEB), electrical conductivity (ECe), CaCO3, concentration available phosphorus AP were investigated soil next ...
We have previously shown that Annexin A8 (ANXA8) is strongly associated with the basal-like subgroup of breast cancers, including BRCA1-associated breast cancers, and poor prognosis; while in the mouse mammary gland AnxA8 mRNA is expressed in low-proliferative isolated pubertal mouse mammary ductal epithelium and after enforced involution, but not in isolated highly proliferative terminal end b...
Multi-temporal land use/land cover (LULC) change analysis is essential for environmental planning and recourses management. Various global LULC datasets are available now. However, they do not show strong consistency on a regional scale mainly time limited. Therefore, high-quality multi-temporal mapping with reasonable still demanding. In this study, using the Landsat 7, 8, NASA digital elevati...
Abstract. In this work, we study the kinetics of gas-phase reactions hydroxyl radicals with cyclohexene oxide (CHO), 1,2-epoxyhexane (EHX), 1,2-epoxybutane (12EB), trans-2,3-epoxybutane (tEB) and cis-2,3-epoxybutane (cEB) using relative rate technique. The experiments were conducted at (298 ± 3) K (760 10) Torr ((1.01 0.01) × 105 Pa) total pressure synthetic air different reference compounds in...
Triazol fungusitler, geniş spektrumlu, steroidal olmayan antiöstrojenler ve çeşitli endüstriyel uygulamalar için yaygın olarak kullanılmaktadır. Toprak, su gibi çevresel ortamlarda canlı organizmaların dokularında bu fungusitlerin kalıntılarına rastlanmaktadır. Giderek artan toksisite raporları, triazol çevre halk sağlığı açısından endişe verici kirleticiler ortaya çıkmasına neden olmuştur. Bu ...
Three types of ethylene oxide-based and carbonate-containing copolymers were prepared through copolymerization oxide (EO) with CO2 under metal-free conditions in the presence triethylborane (TEB), using onium salts (OS) as initiator. Hydrophobic poly[(ethylene carbonate)x-co-(ethylene oxide)y] (PECEO) samples carbonate contents above 90% (x ? y) first a pressure 10–30 bar ratio [TEB] to [OS] 1–...
