In the field of deep geothermal energy, mono-tube design will be increasingly used in future, as significant cost savings can expected production boreholes up to depths 6000 m. The previously bolting pipe lengths by means sleeves contributes significantly construction costs. addition, there is an increased risk failure for sleeve bolting, especially if different materials have layers purpose in...

Flowering time, the major regulatory transition of plant sequential development, is modulated by multiple endogenous and environmental factors. By phenotypic profiling of 80 early flowering mutants of Arabidopsis, we examine how mutational reduction of floral repression is associated with changes in phenotypic plasticity and stability. Flowering time measurements in mutants reveal deviations fr...

Standing crib supports have been applied in underground mining programs to resist large roof movements and sustain highloads. The strength and deformation capability of these systems has been documented under both laboratory and field conditions. The parameter that has not been examined and is not well understood is the effect that a crib or other types of standing support has on the primary an...

Abstract Numerical simulation is a useful tool in investigating the loading performance of rock bolts. The cable structural elements (cableSELs) FLAC3D are commonly adopted to simulate bolts solve geotechnical issues. In this study, bonding interface between bolt and grout material was simulated with two-stage shearing coupling model. Furthermore, FISH language used incorporate shear model into...

Underground tunnel face bolting and pipe umbrella reinforcement are one of the most challenging tasks in construction whether industrial or not, and infrastructures such as roads or pipelines. It is one of the first sectors of economic activity in the world. Through a variety of soil and rock, a cyclic Conventional Tunneling Method (CTM) remains the best one for projects with highly variable gr...

Purpose. To determine the subspecies and variety/sample of garlic with best nutritional value by analy­zing difference between indicators their variation according to time planting (winter or spring). Methods. During 2020–2022, in field conditions (Uman, 48°46’N, 30°14’E) were studied 25 breeding local forms (9 – winter bolting; 9 non- 11 spring, among which samples No. 14, 33, 43 44 determined...

The sensitivity of the Nicotiana plumbaginifolia wild-type and phytochrome B (hlg) mutant to photoperiod was investigated. Leaf number at bolting and rosette-leaf movement were measured under conditions of different light quality and photoperiod. Bolting in wild-type plants was slightly delayed under short days (SD), compared to plants grown under long days (LD). The hlg mutant bolted later tha...

sugar  is very important role  in  humanbeing feed.  for sugar beet  production in tropical area detemine  sowing and  harvesting date is very important . for this reason three sowing date (1 sep, 20 sep and 10 oct) and three harvesting date (15 apr, 15 may and 15 jun) in complete blouck design as factorial with three replication in two year in sarpol area condoucted. results  showed  that  the...
