drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

Downhole microseismics has gained in popularity in recent years as a way to characterize hydraulic fracturing sources and to estimate in-situ stress state. Conventional approaches only utilize part of the information contained in the microseismic waveforms such as the P/S amplitude ratio and/or P first motion polarity to determine the microearthquake focal mechanisms and infer stress state. Thu...

Teleseismic body waveform modeling of the far-field P-and SH-waveforms and spectral analysis of P-waves are used to determine the source parameters of the March 25, 2006 Fin earthquake (mb 5.7). Its epicenter is located at the South of Iran in Hormozgan Province. The waveform modeling results show the earthquake was caused by a thrust motion on a NW-SE striking fault with parameters: Fault plan...

The Jamming transition can be seen as a general phenomenon occurring whenever a dense assembly of “things” gets stuck and resists to an externally applied shear stress. The mechanical response of a vibrated amorphous bi-dimensional packing of grains close to the Jamming transition is investigated. Stress is applied to the media through a constant torque rheometer while surface fraction is tuned...

This case report intends to highlight the space closure with tear drop loop mechanics for bimaxillary protrusion. Loops can be fabricated in a sectional or full arch wire, and closing loops are usually used in loop mechanics for extraction space closure. The major advantage of loop mechanics is the lack of friction between the bracket and arch wire during space closure. An adult patient with bi...

Background: Our study aimed to measure effectiveness of Anti-S1 RBD (receptor binding domain) IgG Antibody levels against SARS (severe acute respiratory syndrome) Cov-2 in breast cancer patients and compare them with healthy participants.
 Methods: This prospective cross-sectional, single-center was designed evaluate antibody following SARS-CoV-2 vaccination 54 56 controls without diagnosi...

The purpose of this study is to get fundamental knowledge of the valve impact stress by clarifying wave propagation mechanism in two bars which are simulated to a valve seat or valve stop and a valve. Axially uniform stress in finite cylindrical elastic bars subjected to velocity-impact loading is considered on the bases of elementary equations of energy. A technique is developed for measuring ...
