Choque

The shock, now known as a clinical syndrome due to a systemic breakdown in tissue perfusion leading to cellular hypoxia, metabolic changes and consequently organ dysfunction, is a condition that affects both humans and animals and should be classified as an emergency. For its dynamic course the therapy becomes a challenge, all the time time spared in diagnosis and treatment is essential to save the patient's life, so knowledge of its physiopathology can become of great value, and in order to clarify it better, shock has been divided didactically into: cardiogenic, hypovolemic, distributive, and obstructive, so the best approach may be chosen to this situation, noting that the therapy in general is the sum of several procedures that aims to compensate for the animal so that the underlying cause of shock may be treated

An evolutionary approach to improve connectivity prediction in mobile wireless sensor networks

Connectivity is the basic factor for the proper operation of any wireless network. In a mobile wireless sensor network it is a challenge for applications and protocols to deal with connectivity problems, as links might get up and down frequently. In these scenarios, having knowledge of the node remaining connectivity time could both improve the performance of the protocols (e.g. handoff mechanisms) and save possible scarce nodes resources (CPU, bandwidth, and energy) by preventing unfruitful transmissions. The current paper provides a solution called Genetic Machine Learning Algorithm (GMLA) to forecast the remainder connectivity time in mobile environments. It consists in combining Classifier Systems with a Markov chain model of the RF link quality. The main advantage of using an evolutionary approach is that the Markov model parameters can be discovered on-the-fly, making it possible to cope with unknown environments and mobility patterns. Simulation results show that the proposal is a very suitable solution, as it overcomes the performance obtained by similar approaches.

Síntese de tetra-hidropiridinas por meio de reações multicomponentes

Multicomponent Reactions are defined as reactions between three or more reagents in a single reaction step in the same reaction vial, forming a product that includes the majority of atoms and structural characteristics of the reagents. Thus these reactions save time and energy. One of the ways to improve the yield and reaction time of a multicomponent reaction is to use different catalysts, an example of catalyst that shows great potential and has been studied in recent years is the molecular iodine is known to be a Lewis acid with high catalytic power. The functionalized piperidines, also known as tetrahydropyridines, are alkaloids that have pharmacological potential, this is due to the piperidine ring present in many natural product structures with muscarinic activity, nicotine, analgesic, antipsychotic, anti-proliferative, among others. In this paper we describe studies about on the application of molecular iodine (I2) in the multicomponent reaction between aniline derivatives, benzaldehyde and β-ketoester (methyl acetoacetate) for the synthesis of functionalized piperidines and the synthesis of a corresponding piperidone by acid hydrolysis. Data analysis allowed us to demonstrate the efficacy of molecular iodine in the synthesis of functionalized piperidines, obtaining results with yields 44-87% and short reaction time of 8 to 24 hours, and the efficacy of acid hydrolysis of enamine in the structure of the tetrahydropyridine derivative in a yield of 81%

Do hexâmetro ao decassílabo: equivalência estilística baseada na materialidade da expressão

This paper deals with the relationship between the Latin hexametre and the Portuguese decasyllable, mainly paying attention to the possibility of a translation which could save some stylistic equivalence based on the proportionality of the materiality of expression.

EC32-713 The Trench Silo in Nebraska

The original idea of using a trench for the storing of ensilage seems to have been the outgrowth of the practice long used in several European countries of storing clover and beet tops in pits. Shortly after the World War, western Canada followed by Montana and North Dakota began to use the trench silo. In Nebraska the true trench silo made its appearance about 1925 or 1926. The trench silo as described in this circular, unless lined with some permanent material such as brick, concrete or stone, must be considered a temporary structure which will serve for a few years only and then must be discarded or rebuilt. In an emergency it will save a crop even though the farmer has little capital to expend other than his own labor.

Review of Prairie Time: A Blackland Portrait by Matt White

Nowadays, the Blackland Prairies of north Texas are the kind of landscape most people think of as great for subdivisions and strip malls: generally flat, easily bulldozed, and not too far from Dallas-Fort Worth. Prairie Time: A Blackland Portrait traces a similar utilitarian vision of the prairie in 19th-century pioneer descriptions as well: good for plowing, grazing, and-once the buffalo and Native Americans are exterminated-not too far from outposts of commerce. The book serves as an environmental jeremiad for a place too easily seen as useful and thus too often ignored for preservation. Matt White gives readers a context in which to begin to value the Blackland Prairie by combining a heartfelt story with a thorough sense of its ecological wonder, our post-settlement history and its environmental impact on the land, and some remarkable stories of current preservationists working to find and save remnant gems of unplowed prairie.

A Novel Cost-Efficient On-Line Intermediate Waveband-Switching Scheme in WDM Mesh Networks

Waveband switching (WBS) is an important technique to save switching and transmission cost in wavelength -division multiplexed (WDM) optical networks. A cost-efficient WBS scheme would enable network carriers to increase the network throughput (revenue) while achieving significant cost savings. We identify the critical factors that determine the WBS network throughput and switching cost and propose a novel intermediate waveband switching (IT-WBS) algorithm, called the minimizing-weighted-cost (MWC) algorithm. The MWC algorithm defines a cost for each candidate route of a call. By selecting the route with the smallest weighted cost, MWC balances between minimizing the call blocking probability and minimizing the network switching cost. Our simulations show that MWC outperforms other wavelength/waveband switching algorithms and can enhance the network throughput at a reduced cost.
