这是一个真实的故事。1997年4月7日公牛主场对阵AI和斯塔克豪斯率领的76人。乔丹坐在板凳上看着艾佛森一人独砍40分。艾弗森气势如虹,整场比赛像是他的个人表演。乔丹一边感叹着后生可畏．一边又对此心生厌恶。突然，乔丹转过身来．向身后的一位媒体记者问了一个问题：我当年是新人的时候也是这样吗？这位大哥思忖了一会儿．对MJ说：“不，迈克．他传球比你当年要多。”

一、引言这篇简要的论文的目的是描述加拿大向法官进行职业道德“教育”。之所以在“教育”两字上加引号,是因为加拿大国家司法研究所（National Judicial Institute）并非在通常的＂教育＂的意义上,向法官们“讲授”职业道德。相反,正如下文所说明的,它只是提供一种平台或论坛,供法官们讨论与司法职业道德有关的问题。

To investigate the grain-size-dependent properties of the magnetic minerals in Chinese loess/paleosol samples(Touxiangdao,Xining,Qinghai province,China),magnetic extracts were divided into two size fractions by gravitational *** the basis of hysteresis measurements,thermal demagnetization of low-temperature saturation isothermal remanent magnetization,and nonmagnetic studies(SEM and XRD) we identified magnetic phases both in the grain size fractions of the magnetic extracts and in the less magnetic residues to provide more accurate and complete descriptions of all the magnetic components in the bulk natural *** results show that the oxidation degree(nonstoichiometry) of magnetic minerals is strongly affected by both grain size and the paleoclimatic environment in which they were deposited and *** ascending order of the oxidation degree of our samples,we find(1) loess-coarse particles (LC) are multidomain(MD) magnetite with slight oxidation,(2) paleosol-coarse(pC) particles are also MD magnetite but with a higher oxidation degree compared to LC, (3) loess-fine(LF) particles are pseudo-single domain(pSD) magnetite with a high oxidation degree,and(4) paleosol-fine(pF) particles are pSD *** domain (SD) and superparamagnetic(Sp) maghemite mainly stay in the *** thermomagnetic analysis of pF(pSD maghemite) revealed that this natural maghemite has a Curie temperature identical to that of magnetite and that the conversion efficiency of transformation from maghemite to hematite is only about 50%after a 700℃heating/ cooling *** new results identify the sources of multicomponent NRM in Chinese loess sequences as well as clarify the paleoenviromental and paleoclimatic controls on the remanence *** TERMS:1512 Geomagnetism and paleomagnetism:Environmental magnetism;1519 Geomagnetism and paleomagnetism:Magnetic mineralogy and petrology;1540 Geomagnetism and paleomagnetism:Rock and mineral magnetism

乔丹被上帝选中,来拯救NBA,拯救我们的灵魂。不要将此称之为回归,因为他一直未曾离开。正如耶稣和马丁路·德金的回归是为了拯救世人的灵魂一般,迈克尔·乔丹重返NBA也绝不仅仅是投几个球而已。

An 89-year-old woman was admitted with a 3-day history of dysphagia and lower jaw twitching. She had a history of hypertension, diabetes mellitus, surgically corrected left proximal humeral fracture, and right C5 dermatome postherpetic neuralgia. The jaw twitching had caused dysphagia with an inability to drink liquids. physical examination confirmed the persistent lower jaw myoclonus (Supplementary Video;http://***/CM9/A48). The patient was fully conscious and had no twitching or nystagmus in any of her other extremities. The results of neurological examination and biochemical analysis (including complete blood profile, electrolyte level, random glucose concentration, renal function test, and liver function test) were all within the normal range. Computed tomography of the brain was unremarkable and an electroencephalogram showed no evidence of seizure. A careful review of her prescribed medications revealed the following: the patient complained of allodynia over the right C5 dermatome around 3 months prior and was prescribed gabapentin. The dosage of gabapentin was increased to 300 mg total dissolved solids (TDS) around 2 months prior. Creatinine levels were normal but her glomerular filtration rate, as estimated by the Cockcroft-Gault equation, was 36 mL/min.[1] Since the patient’s relatives supervised her medication intake, overdosage was not possible. Gabapentin was discontinued and replaced with pregabalin 50 mg BD and the patient was prescribed valium 2 mg TDS transiently. The jaw myoclonus subsided on the second day. After a consultation with a speech therapist, the patient resumed oral intake and remained tolerant of a normal diet. Upon review after 1 month, the patient remained free from jaw myoclonus.
