Do High Birth Rates Hamper Economic Growth?

This paper examines the impact of the birth rate on economic growth by using a panel data set of 28 provinces in China over twenty years. Because China’s one-child policy applied only to the Han Chinese but not to minorities, this unique affirmative policy allows us to use the proportion of minorities in a province as an instrumental variable to identify the causal effect of the birth rate on e...

Why do Bimetallic Clusters have more Chemical Reactivity? Study the VnNim (2 ≤ n + m ≤ 6) Clusters as the Nano Species

This article gives you proof that bimetallic transition metal clusters with the difference in electronegativity are better catalysts than monoatomic one. To prove this fact, a study of ethylene adsorption on bimetallic clusters vanadium-nickel VnNim (2≤n+m≤6) has been demonstrated. Our result shows that hardness has a quite good linear correlation with the non-Lewis of VnNi (n=1-5) cluster (R2=...

Bar codes may have poorer error rates than commonly believed.

By most accounts (1 ), the development of bar code technology is credited to 2 graduate students at Drexel University. In 1948, Bernard Silver had overheard the president of a local grocery chain asking a dean at the University whether they could develop a system to read product information at checkout. Silver told his colleague Norman Woodland of this request. After one failed idea involving u...

Effect of low-phosphate pretreatment of plant species with different relative growth rates on subsequent phosphate uptake.

Do women have poorer outcomes following total knee replacement?

OBJECTIVE To investigate whether women have poorer pain and functional outcomes following total knee replacement (TKR) and to investigate factors that may contribute to this poorer outcome. METHODS In a cohort of 494 people, outcomes were the Pain and Function/Daily Activity subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS) at 6 and 12 months post-surgery. Sequential multiv...
