Objective: This study aims at investigating the relationship between agility performance and perception and decision-making mechanisms of female basketball players.Materials and Methods: A total of seventeen elite female basketball player playing in Second League in Turkey Basketball Federation participated in this study voluntarily. The mean age of the participants was 21.53±2.47 (years), the mean height was 175.67±5.36 (cm) and the mean body weight was 66.80±7.76 (kg). Agility performance of the participants was measured by Newtest Powertimer 300, and perceptual and decision-making parameters were measured by Psychotechnic Vienna test system. Since the number of participants was less than thirty, Spearman Correlation test was applied.Findings: The average perception and decision making parameters of female basketball players were as follows: Visual Perception Test (VPT): 46.82±2.65, Reasoning Test (RT): 88.58±9.43, Response Quality and Speed Test (RQST) number of correct answers: 243.76±14.14, RQST time: 0.78±0.06, Speed and Distance Estimation Test (SDET): 45.00±2.76, Dual-Process Skill and Angle of View Test (DPS-AVT) viewing angle: 99.58±7.72, DPS-AVT collision number of cars: 3.76±2.13 and the number of collisions of DPS-AVT road sides: 3.23±2.01 (Table 1). When the correlation between agility performance (total time) and RQST time and SDET parameters was examined, a negative linear relationship was found (r = 0.842/r = 0.827, p < 0.01). However, agility performance (total time) and VPT, RT, RQST number of correct answers, DPS-AVT viewing angle, DPS-AVT car crash number, DPS-AVT roadsides collision parameters were not statistically significant (p > 0.05).As a result, in training contents, preference of visual stimuli, reaction and prediction studies will be important for improving agility. Furthermore, it is thought that cognitive parameters should be taken into consideration in the selection and orientation of athletes.

Flame Propagation Speed

To complete the experiment on occurrence, development, control and suppression of oil fire and explosion in the enclosed space, this paper developed a variety of simulation experiment platform and data test system of key parameters. This paper developed a series of simulation experiment bench, including simulation experiment bench of narrow enclosed space and volumetric enclosed space, see Fig. 1 to Fig. 2.this paper also developed data test system of key parameters, including the ultra-dynamic data acquisition and analysis system and the flame propagation speed test system, see Fig. 3 to Fig. 4. The experimental results show that these simulation experiment benches can provide comprehensive research conditions and support for oil fire and explosion simulation experiment under various conditions. Compared with the traditional fire sensor, the flame propagation speed test system has the characteristics of high sensitivity, zero false positives, and far detecting distance.

CMP-KDO synthetase (CKS) is an enzyme which plays a key role in the synthesis of LPS, an outer membrane component unique to gram negative bacteria. CKS activates KDO to CMP-KDO for incorporation into LPS. The enzyme is normally present in low concentrations (0.02% of total cell protein) which makes it difficult to perform large scale isolation and purification. Recently, the gene for CKS from E. coli was cloned and various recombinant DNA constructs overproducing CKS several thousandfold (unpublished data) were derived. Interestingly, no cytoplasmic inclusions of overproduced CKS were observed by EM (Fig. 1) which is in contrast to other reports of large proteinaceous inclusion bodies in various overproducing recombinant strains. The present immunocytochemical study was undertaken to localize CKS in these cells.Immune labeling conditions were first optimized using a previously described cell-free test system. Briefly, this involves soaking small blocks of polymerized bovine serum albumin in purified CKS antigen and subjecting them to various fixation, embedding and immunochemical conditions.
