Comparison of Peak Flow Rate and Vital Capacity between District Level and State Level Baseball Players

<p>The purpose of present study was to compare the peak flow rate and vital capacity between district<br>level and state level baseball players. The subjects consist of 30 ( District level:15 and State level:15)<br>randomly selected male baseball players, between the age group of 18 to 28 years, studying at different<br>colleges affiliated to Guru Nanak Dev University, Amritsar, Punjab, India. Peak flow rate was measured with<br>a peak flow meter whereas vital capacity was measured by spirometer.The between-group differences were<br>assessed by using t-test. The level of p<0.05 was considered significant.</p> <p> </p

Zirconocene-Mediated Selective C–C Bond Cleavage of Strained Carbocycles: Scope and Mechanism

Several approaches using organozirconocene species for the remote cleavage of strained three-membered ring carbocycles are described. ω-Ene polysubstituted cyclopropanes, alkylidenecyclopropanes, ω-ene spiro[2.2]­pentanes, and ω-ene cyclopropyl methyl ethers were successfully transformed into stereodefined organometallic intermediates, allowing an easy access to highly stereoenriched acyclic scaffolds in good yields and, in most cases, excellent selectivities. DFT calculations and isotopic labeling experiments were performed to delineate the origin of the obtained chemo- and stereoselectivities, demonstrating the importance of microreversibility
