The lack of detect technology hinders the understanding host-guest (H-G) chemical properties for thiolate-protected tiara-like structural nanoclusters (Mn(SR)2n). In this work, NMR spectroscopy is demonstrated as a powerful tool to probe H-G structure Mn(SR)2n both experimentally and theoretically. A low-field shifting wide shift (CS) signal H nucleus in CH2Cl2 observed spectrum mixture Pd8(PET...
This paper examines the trends in strategic technology partnering (STP) by firms from developing countries over the period 1980-94. The evidence shows that a small group of countries, namely the Asian NICs and Eastern Europe dominate STP activity. We also examine differences in organisational modes and how these have evolved over time, suggesting an increasing similarity between the NICs and Tr...
A large number of local aromaticity indices for the benzenoid rings in polyaromatic hydrocarbons is computed. The results are interpreted, supporting Clar's hypothesis, and mutual correlations are investigated. It is shown that there are good correlations between all indices that strictly allow comparing benzenoid character. Poor correlations are found with NICS. A rationale is offered, yieldin...
This study reports the use of multicenter bond indices as a new tool for the quantitative characterization of homoaromaticity. The approach was applied to the series bicyclic systems whose homoaromaticity was recently discussed in terms of traditional aromaticity index, namely, NICS. In this study we found that the multicenter bond indices are indeed able to quantify the degree of homoaromatici...
Operating systems fail both to efficiently exploit, and to effectively manage, the considerable hardware resources of modern network interface controllers. We survey the kinds of hardware facilities available and their applicability, and then investigate (and critique) the reasons why OS designers eschew core support for such features. We then describe Dragonet, a new network stack design based...
In many newly industrializing countries (NICs), increased international trade activities are often triggered by several advancements, including attracting foreign direct investment (FDI), financial development, and technological changes. Recently, abundant diversified renewable energy sources used in production have also started to take their place among these advancements. Although the relatio...
در این پژوهش، اثر عامل دار کردن فولرین ها در آروماتیسیته ی مولکولهای c60 تا c 20 بررسی شد. با بررسی نتایج حاصل از محاسبات مشخص شد که یک رابطه ی کلی بین ساختار، انرژی و داده های ترموشمی این مولکول ها وجود دارد، همچنین نحوه ی قرارگیری پنج ضلعی ها و شش ضلعی ها اثر مستقیم روی مقدار nics فولرین مربوطه دارد، چنانچه هر چه توزیع حلقه های شش ضلعی بین 12 پنج ضلعی بیشتر و یکنواخت تر باشد، nics منفی تر و د...
This article investigates the impact of export product diversification, extensive margin and intensive on emerging economies energy demand covering period from 1971 to 2014. The study contributes economics by unveiling interaction between diversification 10 newly industries countries (NICs). Owing growth prospect trade volume these nations, it is necessary assess various facades demand. In this...
