报道了采自云南省景东县的牛蛭属Poecilobdella Blanchard,18931新种。由于新种总体环数为99环,生殖孔分别在30(Ⅺ)与38(ⅩⅢ)环内,两孔相隔7环;肛门在99环与尾吸盘交界线上;附睾呈卵圆形,精管膨腔呈梨形并且为前者的1/3大小;阴道盲囊呈圆球形,阴道管粗短且无阴道柄。因此与本属中所有的已知种均不相同。

Si_(0.75)Ge_(0.25)虚衬底上应变补偿Si/Si_(0.62)Ge_(0.38)量子阱发光

由于Si/SiGe异质结构的带阶差主要发生在价带,为实现高效率的发光,本文从理论上设计了在硅基Si_(1-x) Ge_x虚衬底上外延应变补偿的Si/S_(1-y) Ge_y(y>x)量子阱的能带结构,将量子阱对电子的限制势垒提高到100meV以上.在实验上,采用300℃生长的Ge量子点插入层,制备出薄的SiGe驰豫缓冲层(虚衬底),表面Ge组份达到0.25,表面粗糙度小于2nm,驰豫度接近100%.在我们制备的SiGe缓冲层上外延了应变补偿SiGe/Si多量子阱结构,并初步研究了其发光特性.

SATELLITE REMOTE-SENSING PREDICTION OF JAPANESE PILCHARD FISHING GROUND IN THE HUANGHAI SEA AND THE EAST-CHINA-SEA

The thermophily, fishing season and central fishing ground of Japanese pilchard (Sardinops melanosticta) were studied by using satellite remote sensing (SRS) and other methods in Haizhou Bay and Tsushima waters during 1986-1990. A rapid prediction method of fishing ground is presented. Moreover, the results indicated that the thermophilic values of the fish stock are 11-20 degrees C and both fishing grounds are in increasing temperature process from the beginning to the end of the fishing period. The Japanese pilchards gather vigorously at the sea surface temperature of 15-17 degrees C. The water temperature is a key factor affecting the fishing season and the catch of the fishing ground. The increasing temperature process restricts the fishing season development and central fishing ground formation. The accuracy of 15 predictions made in the Haizhou Bay fishing ground is up to 91.3%, and 37 predictions made in the Tsushima, fishing ground shorten the fish detection time by 13.4% - 22% on the average.

Anthropometry of the Breast Region: How to Measure?

Breast region measurements are important for research, but they may also become significant in the legal field as a quantitative tool for preoperative and postoperative evaluation. Direct anthropometric measurements can be taken in clinical practice. the aim of this study was to compare direct breast anthropometric measurements taken with a tape measure and a compass.Forty women, aged 18-60 years, were evaluated. They had 14 anatomical landmarks marked on the breast region and arms. the union of these points formed eight linear segments and one angle for each side of the body. the volunteers were evaluated by direct anthropometry in a standardized way, using a tape measure and a compass.Differences were found between the tape measure and the compass measurements for all segments analyzed (p > 0.05).Measurements obtained by tape measure and compass are not identical. Therefore, once the measurement tool is chosen, it should be used for the pre- and postoperative measurements in a standardized way.This journal requires that authors assign a level of evidence to each article. for a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266.

Megiston agathon (Pl. Ap. 38 a) – Sedno życia i filozoficznego wyzwania Sokratesa

We suggest a certain minimal approach to the historical Socrates on the basis of Plato’s Apology. This text makes it possible to reconstruct the authentic charge and the defense line of Socrates, as well as his motivation and the quintessence of his philosophical challenge. The most important thing is what the philosopher says in the face of his death sentence: that the greatest good for a man is to live an examined life focusing on virtues and ethical values. Unfortunately, the preponderance of studies, even the most recent ones, fail to recognize the philosopher’s provocative challenge, whilst it is not only a crucial motif in the Socratic examining (ἐξετάζειν), i.e. testing the interlocutors’ knowledge by means of irony, elenchos and aporia, but also an inspiration for his direct and indirect followers in seeking virtues and the greatest good.

Nomenclature and syntaxonomic notes on some high-rank syntaxa of the European grassland vegetation

We present descriptions of a new order (Ranunculo cortusifolii-Geranietalia reuteri and of a new alliance (Stachyo lusitanicae-Cheirolophion sempervirentis) for the herbaceous fringe communities of Macaronesia and of the southwestern Iberian Peninsula, respectively. A new alliance, the Polygalo mediterraneae-Bromion erecti (mesophilous post-cultural grasslands), was introduced for the Peninsular Italy. We further validate and typify the Armerietalia rumelicae (perennial grasslands supported by nutrient-poor on siliceous bedrocks at altitudes characterized by the submediterranean climate of central-southern Balkan Peninsula), the Securigero-Dasypyrion villosae (lawn and fallow-land tall-grass annual vegetation of Italy), and the Cirsio vallis-demoni-Nardion (acidophilous grasslands on siliceous substrates of the Southern Italy). Nomenclatural issues (validity, legitimacy, synonymy, formal corrections) have been discussed and clarified for the following names: Brachypodio-Brometalia, Bromo pannonici-Festucion csikhegyensis, Corynephoro-Plantaginion radicatae, Heleochloion, Hieracio-Plantaginion radicatae, Nardetea strictae, Nardetalia strictae, Nardo-Callunetea, Nardo-Galion saxatilis, Oligo-Bromion, Paspalo-Heleochloetalia, Plantagini-Corynephorion and Scorzoneret alia villosae. 

La existencia de necesidades de información y comportamiento informativo en los entrenadores en deportes de combate

Este trabajo tiene como propósito esencial, realizar un acercamiento para detectar e identificar las necesidades de información y el comportamiento informativo de entrenadores en deportes de combate. Para ello se aplicó un cuestionario a instructores de aikido, boxeo, esgrima, judo, karate, kendo, lima lama, lucha y taekwondo seleccionados mediante un muestreo no probabilístico por causalidad. En general encontramos que los principales temas de interés entre los instructores son: los programas de entrenamiento, nutrición y dietas de entrenamiento. Por otra parte, los entrenadores son más propensos a utilizar su experiencia, internet y cursos para obtener información. En contraste se nota que la biblioteca y los libros son poco usados.
