‎in this paper we introduce the concept of order difference interval graph $gamma_{odi}(g)$ of a group $g$‎. ‎it is a graph $gamma_{odi}(g)$ with $v(gamma_{odi}(g)) = g$ and two vertices $a$ and $b$ are adjacent in $gamma_{odi}(g)$ if and only if $o(b)-o(a) in [o(a)‎, ‎o(b)]$‎. ‎without loss of generality‎, ‎we assume that $o(a) leq o(b)$‎. ‎in this paper we obtain several properties of $gamma_...

STUDY DESIGN Prospective cohort study along with questionnaire. PURPOSE To measure the correlation of the visual analogue score (VAS), with (Oswestry disability Index [ODI], version 2.1a) in English, and modified ODI (English and Hindi version). To validate translated version of the modified ODI in English version to Hindi. OVERVIEW OF LITERATURE Conflicting evidence in literature regarding...

Outward direct investment (ODI) from the People’s Republic of China (PRC) is surging. A common perception is that it was driven by the country’s resourceseeking and technology-seeking motives. Using a new, unique, and comprehensive dataset that covers close to 10,000 Chinese ODI deals from 1998 to 2009, we find that in contrast to the common perception, over half of the ODI deals are in service...

Incorporating the Healthy Eating Index concept, we have developed a global dietary quality index, the Overall Dietary Index (ODI). We have evaluated the relationships between ODI and chronic disease in a 1998 Taiwanese Health Screening program with over 46,000 members (51.2% females) aged 19-84. However, it could not predict health status adequately. Therefore, we revised this ODI which became ...

BACKGROUND Disputes exist regarding the psychometric properties of the Oswestry Disability Index (ODI). The present study was to examine the reliability, validity, and dimensionality of a Chinese version of the ODI version 2.1 in a sample of 225 adult orthopedic outpatients with chronic low back pain [mean age (SD): 40.7 (11.4) years]. METHODS We conducted reliability analysis, exploratory bi...

OBJECTIVE To study the influence of obstructive sleep apnea (OSA) on 24-h BP. SETTING Sleep laboratory of the Medical Department, Neukölln Hospital, Berlin, Germany. METHODS In 93 subjects, noninvasive 24-h BP monitoring was performed with BP recordings made at 15-min intervals. Apnea severity was evaluated by means of a portable device that allows calculation of an oxygen desaturation inde...

The current study investigated the night-to-night variability and diagnostic accuracy of the oxygen desaturation index (ODI), as measured by ambulatory monitoring, in the diagnosis of mild and moderate obstructive sleep apnoea-hypopnoea syndrome. To assess the variability of the ODI, 35 patients were monitored at home during 7 consecutive nights by means of a portable recording device, the MESA...
