The International Year of Planet Earth＇s triennial programme was launched is some style, and on three continents, in January 2007. Geoscientists from ＂the round Earth＇s imagined comers＂ gathered for the inaugural meeting of the Board of the International Year of Planet Earth （IYPE） Corporation on 9 and 10 January 2007. The 15 Board Members （Figure 1） were joined by IYPE National Committee representatives, International and Associate Partners, observers and by Professor Aubrey Manning, a Goodwill Ambassador of the IYPE.

The pressure versus temperature phase diagram of a shoulder-like potential is exactly computed in one system of particles interacting through a multiscale dimension. The N-shoulder potential exhibits N density anomaly regions in the phase diagram if the length scales can be connected by a convex curve The result is analyzed in terms of the convexity of the Gibbs free energy.

Last December the United Nations General Assem- bly voted unanimously to approve 2008 as Interna- tional Year of Planet Earth. This ambitious research and outreach project, which will actually extend over three years, is Earth science＇s big chance to put itself back at the centre of public science awareness.

The zeta potential, isoelectric point, and agglomeration of ***3 （LLTO） nanoparticles dispersed in aqueous media at different ionic strengths have been studied. The zeta potential was determined from electrophoretic mobility measurements, according to Smoluchowski＇s equation, for Li0.5La0.5TiO3 suspen- sions in NaCl and KCI electrolytes with ionic strengths of 1, 10, and 100 mmol/dm3. The isoelectric point （IEP）, zeta potential （ζ）, and the agglomeration were shown to strongly depend on the ionic strength of the Li0.5La0.5TiO3 aqueous colloidal suspension in both NaCI and KCI electrolytes, which allows the deter- mination of the effects of environmental conditions for ***3 manipulation in aqueous colloidal systems. The suspensions of Li0.5La0.5TiO3 nanoparticles reach the IEP in the pH range 0f3-5. The （ of Li0.5La0.5TiO3 nanoparticles varied from positive to negative values with a pH increase, which allows for the control of the surface charge depending on the purpose. The pH range of 7-g and an ionic strength ≤1 mmol/dm3 are recommended as the most suitable conditions for both the LLTO colloidal shaping techniques application and the LLTO-based nanocomposite formation.

Small bowel obstructions （SBOs） are primarily caused by adhesions, hernias, neoplasms, or inflammatory strictures. Intraluminal strictures are an uncommon cause of SBO. This report describes our findings in a unique case of sequential, stenotic intraluminal strictures of the small intestine, discusses the differential diagnosis of intraluminal intestinal strictures, and reviews the literature regarding intraluminal pathology.

Objectives:Foodborne disease outbreaks linked to fruits and vegetables have been increasing in occurrence worldwide;therefore,the aim of this study was to identify the reported foodborne outbreaks associated with fruit and vegetable consumption in Brazil from 2008 to *** And Limitations:Thirty produce related outbreaks resulted in 2926 illnesses,347 hospitalizations,and no *** bacterial pathogens were identified as etiological *** these,Salmonella was the most frequent(30 per cent of outbreaks)followed by Staphylococcus aureus(23.3 per cent),Escherichia coli(10 per cent),Bacillus cereus(6.6 per cent),and thermotolerant coliforms(3.3 per cent),whereas etiological agents could not be determined for 26.6 per cent of *** most common food vehicles implicated in outbreaks were generically named as fruits and vegetables(46.6 per cent of outbreaks).The term salad was used generically and specifically like salads(two outbreaks),raw/cooked salads(four outbreaks),vegetable salad,tropical salad,Caesar salad,and raw salad of cabbage and *** one outbreak was related exclusively to fruit(fruit pulp),whereas other outbreaks were related to cooked carrot,lettuce,cucumber,watermelon/cabbage,and chard/*** sources and issues related to the future control of produce-related foodborne disease outbreaks are discussed.

In this paper we consider the problem of“end-to-end”digital camera identification by considering sequence of images obtained from the *** problem of digital camera identification is harder than the problem of identifying its analog counterpart since the process of analog to digital conversion smooths out the intrinsic noise in the analog *** it is known that identifying a digital camera is possible by analyzing the camera’s intrinsic sensor artifacts that are introduced into the images/videos during the process of photo/video *** is known that such methods are computationally intensive requiring expensive pre-processing *** this paper we propose an end-to-end deep feature learning framework for identifying cameras using images obtained from *** conduct experiments using three custom datasets:the first containing two cameras in an indoor environment where each camera may observe different scenes having no overlapping features,the second containing images from four cameras in an outdoor setting but where each camera observes scenes having overlapping features and the third containing images from two cameras observing the same checkerboard pattern in an indoor *** results show that it is possible to capture the intrinsic hardware signature of the cameras using deep feature representations in an end-to-end *** deep feature maps can in turn be used to disambiguate the cameras from each *** system is end-to-end,requires no complicated pre-processing steps and the trained model is computationally efficient during testing,paving a way to have near instantaneous decisions for the problem of digital camera identification in production *** we present comparisons against the current state-of-the-art in digital camera identification which clearly establishes the superiority of the end-to-end solution.
