The electrochemical oxidation behaviors of NaBH4 on Zn, Zn–MH, and MH (metal-hydride) electrodes were investigated, and an intrinsic direct orohydride fuel cell (DBFC)/battery hybrid power source using MH (or Zn–MH) as the anode and MnO2 as the cathode was tested. Borohydride annot be effectively oxidized on Zn electrodes at the Zn oxidation potential because of the poor electrocatalytic abilit...

accounts and narratives of the ancient iranian texts and sources of the islamic period concerning fereydun indicate that this iranian dragon-slayer hero has been known for his three powers, that is “fighting powers,” “medical skills,” and “sorcery arts”. on the other hand, his name, fereydun (middle persian “frēdōn”, avestan “θraētaona-“), seems to mean “the owner of three powers” or “the one w...

We study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict. Our experimental results suggest: In a simple bargaining game with an exogenous mediation proposal, the likelihood of conflict is independent of the balance of power. If bargaining involves endogenous demand choices, however, the likelihood of conflict is higher if power is more imbalanced. E...

The aim of the study was to identify the motor structures that determine achievement of top results in karate. The study included a sample of 85 karateka aged 18-29 years, competing as senior category athletes of the Croatian Karate Society. Fourteen motor tests (9 basic motor tests and 5 specific motor tests) were used to assess technical efficiency; fighting efficiency was estimated on the ba...

BACKGROUND Physical fighting is an assaultive behaviour that can lead to injury. Family affluence is a health determinant that can influence injury. This study examines the relationship between family affluence and two outcomes: physical fighting and fighting-related injury in Canadian adolescents. Three measurements were used to represent family affluence and assess whether these measures demo...

Abstract Contemporary critics of the administrative state are right to highlight dangers vesting too much power in a centralized bureaucracy removed from popular oversight and accountability. Too often neglected this literature, however, little state, which enables dominant groups further expand their social economic advantages through decentralized means. This article seeks synthesize these co...
