Behavior based safety (bbs) prevention of employees at workplace

Behavior Based Safety (BBS) is a course of action that informs management and employees of the general safety of the workplace through safety observations. BBS is proposed to focus workers' attention on their own and their peers' daily safety behavior. Then it is a process aimed at reinforcing daily behavior by employees and leaders through safety prevention, reducing the risks of accidents in the workplace

Effect of piston bowl geometry and different injection pressure on the performance, emission and combustion characteristics of diesel engine using biodiesel blend

The shape of the piston cavity, variable injection pressure and variable compression ratio are main input parameters to give better atomization of fuels and high swirling induction that improves the Diesel engine performance, combustion, and emissions characteristics. In this study, the engine test was carried out to improve the combustion, performance, and emissions with the use of two different pistons namely hemispherical shaped piston (standard engine), and toroidal cavity piston with varied injection pressures in a single-cylinder direct injection Diesel engine using 25% of corn oil methyl ester-diesel blend (COME25). Initially, the piston bowl was modified to toroidal combustion chamber with tangential cut on circumference of the piston crown in a standard piston of hemispherical type combustion chamber. The engine speed, compression ratio, and injection timing were kept constant and the results of toroidal combustion chamber compared with base engine piston of hemispherical combustion chamber using diesel and COME25 fuel. The results showed that the toroidal combustion chamber has improved performance, combustion and emissions with the exception of NOx emissions

Not AvailableHigh-density planting of cotton at recommended spacing of 60×10 cm facilitates mechanical harvesting of cotton since the system increases the height of lowest boll. Considering the non-availability and poor penetration of planters in the high-density cotton farms in the country which is tedious and labourious, a study was undertaken to optimize the functional components of the existing five planters so as to enhance availability of the planter for high-density planting of cotton. Observations were taken on intra-row spacing at a strip of 8 m length for each treatment. From the results, it was concluded that the CIAE tractor operated pneumatic planter and CIAE inclined plate planter were the ideal planters among the selected ones for high-density planting system of cotton.Not Availabl

Identification and Characterization of Process-Related Impurities of Trans-Resveratrol

This article deals with the identification and characterization of process-related impurities of trans-resveratrol (3,5,4\u27-trihydroxystilbene), which exhibits several health benefits, including cancer prevention. During the synthesis of the bulk drug resveratrol, three new impurities were observed. The impurities were detected using the high-performance liquid chromatographic (HPLC) method, whose area percentages ranged from 0.05 to 0.3%. A systematic study was carried out to characterize them. These impurities were isolated by preparative HPLC and characterized by spectral data, subjected to co-injection in HPLC, and were found to be matching with the impurities present in the sample. LC-MS was performed to identify the mass of these impurities. Based on their spectral data (IR, NMR, and Mass), these impurities were characterized as 2-benzyl-5-[(E)-2-(4-hydroxyphenyl)ethenyl]benzene-1,3-diol [Impurity-B], 3-(benzyloxy)-5-[(E)-2-(4-hydroxyphenyl)ethenyl]phenol [Impurity-C], 5-{(E)-2-[4-(benzyloxy)phenyl]ethenyl}benzene-1,3-diol [Impurity-D). These compounds are not reported earlier as process-related impurities

Lateral MI Explains the Presence of Prominent R Wave (R ≥ S) in V1.

AIMS: It is necessary to clarify if the presence of a prominent R wave in V1 , in post-myocardial infarction (MI) patients, is due to the involvement of the posterior wall (currently inferobasal segment) or the lateral wall (as has been demonstrated recently by electrocardiographic contrast-enhanced cardiac magnetic resonance [ECG-CE-CMR] correlations studies). METHODS: In 155 patients with inferolateral zone MI, as detected by CE-CMR, the following ECG parameters were evaluated and correlated with MI location according to CE-CMR: R/S ratio in V1 ≥ 1 (classic criteria for posterior MI), R/S ratio in V1 ≥ 0.5, and R in V1 ≥ 3 mm. RESULTS: R/S ≥ 1 criterion: Present in 20 cases: 3 of lateral MI, 17 of inferolateral MI, 0 of inferior MI. Absent in 135 cases, 81 of lateral/inferolateral MI (28/53), 54 of inferior MI (SE 19.8%, SP 100%). R/S ≥ 0.5 criterion: Present in 47 cases: 6 of lateral MI, 39 of inferolateral MI, 2 of inferior MI. Absent in 108 cases, 56 of lateral/inferolateral MI (25/31), 52 of inferior MI (SE 44.6%, SP 96.4%). R ≥ 3 mm criterion: Present in 30 cases: 5 of IM lateral, 23 of inferolateral MI, 2 of inferior MI. Absent in 125 cases, 73 lateral/inferolateral MI (26/47), 52 inferior MI (SE 27.7%, SP 96.4%). CONCLUSIONS: The presence of prominent the R wave in V1 is due to the lateral MI and not to the involvement of inferobasal segment of inferior wall (old posterior wall)
