This paper gives an overview of phenomena associated with particles and bubbles in continuously cast steel. During steel processing from deoxidation to solidification the inclusion population undergoes changes with opportunities of removal. Flotation is an important separation mechanism. Inclusion particles may accumulate in the solidifying strand, thus forming enriched bands, which depend on the type of casting machine. Bubbles are created during inert gas injection. They also change in size, can float out, but also form accumulation bands. The interaction of bubbles and particles is discussed. Internal structure that recently has been observed on the inner surface of bubbles will be reviewed.

Early generation breeding nurseries with thousands of genotypes in single-row plots are well suited to capitalize on high throughput ***,methods to monitor the intrinsically hard-to-phenotype early development of wheat are yet *** aimed to develop proxy measures for the rate of plant emergence,the number of tillers,and the beginning of stem elongation using drone-based *** used RGB images(ground sampling distance of 3mm pixel-1)acquired by repeated flights(≥2 flights per week)to quantify temporal changes of visible leaf *** exploit the information contained in the multitude of viewing angles within the RGB images,we processed them to multiview ground cover images showing plant pixel *** on these images,we trained a support vector machine for the beginning of stem elongation(GS30).Using the GS30 as key point,we subsequently extracted plant and tiller counts using a watershed algorithm and growth modeling,*** results show that determination coefficients of predictions are moderate for plant count(R^(2)=0:52),but strong for tiller count(R^(2)=0:86)and GS30(R^(2)=0:77).Heritabilities are superior to manual measurements for plant count and tiller count,but inferior for GS30 *** the selection intensity due to throughput may overcome this *** image traits can replace hand measurements with high efficiency(85-223%).We therefore conclude that multiview images have a high potential to become a standard tool in plant phenomics.

BACKGROUND The clinical presentation of gastroesophageal reflux disease(GERD) shows a large symptom variation also in different intensities among patients. As several studies have shown, there is a large overlap in the symptomatic spectrum between proven GERD and other disorders such as dyspepsia, functional heartburn and/or somatoform *** To prospectively evaluate the GERD patients with and without somatoform disorders before and after laparoscopic antireflux *** In a tertiary referral center for foregut surgery over a period of 3 years patients with GERD, qualifying for the indication of laparoscopic antireflux surgery, were investigated prospectively regarding their symptomatic spectrum in order to identify GERD and associated somatoform disorders. Assessment of symptoms was performed by an instrument for the evaluation of somatoform disorders[Somatoform Symptom Index(SSI) > 17]. Quality of life was evaluated by Gastrointestinal Quality of Life Index(GIQLI).RESULTS In 123 patients an indication for laparoscopic antireflux surgery was established and in 43 patients further medical therapy was suggested. The portion of somatoform tendencies in the total patient population was 20.48%(34 patients).Patients with a positive SSI had a preoperative GIQLI of 77(32-111). Patients with a normal SSI had a GIQLI of 105(29-140)(P < 0.0001). In patients with GERD the quality of life could be normalized from preoperative reduced values of GIQLI102(47-140) to postoperative values of 117(44-144). In patients with GERD and somatoform disorders, the GIQLI was improved from preoperative GIQLI 75(47-111) to postoperative 95(44-122)(P < 0.0043).CONCLUSION Patients with GERD and associated somatoform disorders have significantly worse levels of quality of life. The latter patients can also benefit from laparoscopic fundoplication, however they will not reach a normal level.

Oscillation and Surface Mark Patterns in Slab Casting

Correlation of Lopingian to Middle Triassic Palynozones

Transverse surface cracks are caused by stresses and strains during casting and occur mostly in oscillation marks. Classical theory relates the depth of marks to the negative strip time and predicts the pitch of marks as given by the mould *** of mark spacing and depth under thick slab casting conditions at low casting speeds offers a chance to extend the knowledge into previously unexplored ranges.A large data set of profilometer sections from various casting parameters and some very long samples have been analyzed with respect to mark pitch and *** results are contrasted with the classical theory of oscillation *** conclusions on the mechanism of mark formation are drawn.

Terrestrial floras underwent important changes during the Lopingian （Late Permian）, Early Triassic, and Middle Triassic, i.e., before, during, and after the end-Permian mass extinction. An accurate account of these developments requires reliable correlation. Macrofossils of land plants can only provide a low-resolution biostratigraphy, while detailed zonation schemes based on palynomorphs are available for many regions. Their applicability is still limited due to several factors, such as （micro-）floral provincialism, a lack of suitable marker taxa commonly occurring at important boundaries, and in many cases a lack of independent age control. Nevertheless, these palynostratigraphic schemes are regularly used for dating and correlation of successions between different regions. To support such efforts, the biozonation schemes based on palynomorphs from the Lopingian up to and including the Middle Triassic from across the world are summarized and revised. Thus, a consistent correlation of palynozones with the currently recognized international stages is established.

当人们通览宗教和世界观自由的基本权利在过去十几年里的实际运用和法教义学上的发展时,很难忽略其在规范性轮廓上萎缩这一事实。这一现象由构成要件要素的发展上更多地考虑主观标准所承载,并且经由联邦宪法法院在司法判例中对有关限制问题的决断性的、限制性的判决而被强化。因此,相对于依据宗教或者世界观的动机而提起的个人的发展请求,一般的法治国规范的有效领域持续地受到限制。当相关现象的潜在冲突在德国呈现趋势性增长的时候,这样的判断就显得越发的危险。

＜正＞Introduction Photorhabdus luminescens,the gram-negative bacterium symbiotically associated with entomopathogenic nematodes of the genus Heterorhabditis is known to be very susceptible to physiological changes triggered by environmental factors（Krasomil-Osterfeld, 1995）.The mechanisms involved are not yet fully understood,and under in vitro culture conditions the complexity of the reaction pattern is mostly experienced as high variability in experiments realised with this bacterium.

Soil salinity is one of the most severe abiotic stress factors threatening agriculture worldwide. Hence,particular interest exists in unraveling mechanisms leading to salt tolerance and improved crop plant performance onsaline soils. Barley is considered to be one of the most salinity-tolerant crops, but varying levels of tolerance are wellcharacterized. A proteomic analysis of the roots of two contrasting cultivars （cv. Steptoe and cv. Morex） is *** plants were exposed to a period of 1, 4, 7, or 10 d at 0, 100, or 150mM NaCI. The root proteome was analyzedbased on two-dimensional gel electrophoresis. A number of cultivar-specific and salinity stress-responsive proteins wereidentified. Mass spectrometry-based identification was successful for 74 proteins, and a hierarchical clustering analysisgrouped these into five clusters based on similarity of expression profile. The rank product method was applied to sta-tistically access the early and late responses, and this delivered a number of new candidate proteins underlying salinitytolerance in barley. Among these were some germin-like proteins, some pathogenesis-related proteins, and numerousas-yet uncharacterized proteins. Notably, proteins involved in detoxification pathways and terpenoid biosynthesis weredetected as early responsive to salinity and may function as a means of modulating growth-regulating mechanisms andmembrane stability via fine tuning of phytohormone and secondary metabolism in the root.
