中兽医治疗马伤料

伤料系牲畜食精料特别是食生精料过多,食多役少,谷气伤于胃腑,凝滞于脾胃,使运化功能失职,邪热、谷气、料毒妄行于脏腑,致使减草恶料,四肢拘急疼痛的一种病证。本文就该病的中兽医验方疗法做一介绍,供大家参考。1病因病理本病多为食欲旺盛之畜,食生精料过多,劳役、乘骑太少;或饲后拴系、缺乏运动,使谷豆生料滞积胃腑,谷气料毒损伤胃气,致胃不腐熟,脾不运化,料毒积于胃肠之中;或因饱喂谷豆料后,使役过重,负重急奔,长途运输劳役,喂饮失节,致使谷豆料停积于胃肠,不能回转运化。

浅谈家畜伤料的证治

家畜伤料多因突然改变饲料或偷食大量精料、或使役减少所致。证见绝食或厌食精料,常打呵欠、耳搭头低、口色红、苔黄厚腻、口内干臭或酸臭难闻、粪中常含有不消化饲料、酸臭味烈、脉沉涩等症状。治疗:治宜消食导滞、理气和胃。方药:马用曲蘖散(神曲、麦芽、山楂、甘草、厚朴、枳壳、陈皮、青皮、苍术);

一例马匹料伤五攒痛的治疗

据《元亨疗马集》载:“五攒痛者,气血凝滞于蹄也”[1]。五攒痛是动物临床常见病之一,由于食用精料过多引发消化系统紊乱,继而因体内吸收毒素而发病,故称为料伤五攒痛,也有因使役过重或持久乘骑而发病,又称为走伤五攒痛。近日,青海省牦牛繁育推广服务中心采用水乌钙疗法治疗一例马匹料伤五攒痛,疗效明显。

中西医结合治疗料伤五攒痛

料伤五攒痛相当于西兽医的急性蹄叶炎。本病常发生于两后肢或两前肢,或者四肢同时发病。由于本病的典型症状是四肢聚于腹下,腰曲头低,形似五攒的特征,故中兽医称为五攒痛。1病因病机多因饲喂精料太多,饲料骤变,饱后使役急促,卒至卒栓,缺乏牵散,痞气结在胸中,淤血凝于蹄,遂成其患。亦可因肠黄或结症所继发,谷气料毒凝于脾胃,脾失健运,侵于经络,凝于蹄头而作痛。

Granular Effect of Fly Ash Repairs Damage of Recycled Coarse Aggregate

Repairing effect of fly ash （FA） on damage of recycled coarse aggregate was evaluated by characteristics of pores and cracks in the vicinity of interracial transition zone （ITZ）. The interracial structure between the virgin aggregate and the attached old mortar was investigated and compared with ITZ of recycled aggregate concrete in the presence of FA or ultra-fine FA（UFA） by means of scanning electron microscope （SEM）. Diameter and plumpness frequency distribution of pores as well as width of the old ITZ, length of contacting points and cracks density were analyzed. The SEM results reveal that the diameter of pores is decreases significantly but pores plumpness increases. A decreased ITZ width and cracks density as well as an increased bonding zone length can also been observed, which indicates that FA or UFA repairs damage of recycled coarse aggregate due to its granular effect.

Relationship between subsurface damage and surface roughness of ground optical materials

A theoretical model of relationship between subsurface damage and surface roughness was established to realize rapid and non-destructive measurement of subsurface damage of ground optical materials.Postulated condition of the model was that subsurface damage depth and peak-to-valley surface roughness are equal to depth of radial and lateral cracks in brittle surface induced by small-radius(radius≤200 μm)spherical indenter,respectively.And contribution of elastic stress field to the radial cracks propagation was also considered in the loading cycle.Subsurface damage depth of ground BK7 glasses was measured by magnetorheological finishing spot technique to validate theoretical ratio of subsurface damage to surface roughness.The results show that the ratio is directly proportional to load of abrasive grains and hardness of optical materials,while inversely proportional to granularity of abrasive grains and fracture toughness of optical materials.Moreover,the influence of the load and fracture toughness on the ratio is more significant than the granularity and hardness,respectively.The measured ratios of 80 grit and 120 grit fixed abrasive grinding of BK7 glasses are 5.8 and 5.4,respectively.

Statistical damage model for quasi-brittle materials under uniaxial tension

Based on the parallel bar system, combining with the synergetic method, the catastrophe theory and the acoustic emission test, a new motivated statistical damage model for quasi-brittle solid was developed. Taking concrete for instances, the rationality and the flexibility of this model and its parameters-determining method were identified by the comparative analyses between theoretical and experimental curves. The results show that the model can simulate the whole damage and fracture process in the fracture process zone of material when the materials arc exposed to quasi-static uniaxial tensile traction. The influence of the mesoscopic damage mechanism on the macroscopic mechanical properties of quasi-brittle materials is summarized into two aspects, rupture damage and yield damage. The whole damage course is divided into the statistical even damage phase and the local breach phase, corresponding to the two stages described by the catastrophe theory. The two characteristic states, the peak nominal stress state and the critical state are distinguished, and the critical state plays a key role during the whole damage evolution course.

Effects of different flui replacements on serum HSP70 and lymphocyte DNA damage in college athletes during exercise at high ambient temperatures

Purpose：The aim of this study was to investigate the effects of flui replacement by water or sports drinks on serum heat shock protein 70（HSP70） levels and DNA damage during exercise at a high ambient temperature.Methods：Ten male college athletes with an athletic career ranging from 6 to 11 years were recruited from Yonsei University.The subjects ran on a treadmill at 75% of heart rate reserve during 4 different trials：thermoneutral temperature at 18℃（T）,high ambient temperature at 32℃ without flui replacement（H）,high ambient temperature at 32℃ with water replacement（HW）,and high ambient temperature at 32℃ with sports drink replacement（HS）.During each condition,blood samples were collected at the pre-exercise baseline（PEB）,immediately after exercise（IAE）,and60 min post-exercise.Results：Skin temperature significant y increased during exercise and was significant y higher in H compared to T and HS at IAE.Meanwhile,serum HSP70 was significant y increased in all conditions at IAE compared to PEB and was higher in H compared to T at the former time point.Significant y increased lymphocyte DNA damage（DNA in the tail,tail length,tail moment） was observed in all trials at IAE compared to PEB,and attenuated DNA damage（tail moment） was observed in HS compared to H at IAE.Conclusion：Acute exercise elevates serum HSP70 and induces lymphocyte DNA damage.Fluid replacement by sports drink during exercise at high ambient temperature can attenuate HSP response and DNA damage by preventing dehydration and reducing thermal stress.

Nonlinear Dynamic Buckling of Damaged Composite Cylindrical Shells

Based on the first order shear deformation theory(FSDT), the nonlinear dynamic equations involving transverse shear deformation and initial geometric imperfections were obtained by Hamilton's philosophy. Geometric deformation of the composite cylindrical shell was treated as the initial geometric imperfection in the dynamic equations, which were solved by the semi-analytical method in this paper. Stiffness reduction was employed for the damaged sub-layer, and the equivalent stiffness matrix was obtained for the delaminated area. By circumferential Fourier series expansions for shell displacements and loads and by using Galerkin technique, the nonlinear partial differential equations were transformed to ordinary differential equations which were finally solved by the finite difference method. The buckling was judged from shell responses by B-R criteria, and critical loads were then determined. The effect of the initial geometric deformation on the dynamic response and buckling of composite cylindrical shell was also discussed, as well as the effects of concomitant delamination and sub-layer matrix damages.

Potential of acoustic emissions from three point bending tests as rock failure precursors

Development of failure in brittle materials is associated with microcracks,which release energy in the form of elastic waves called acoustic emissions. This paper presents results from acoustic emission measurements obtained during three point bending tests on Nestos marble under laboratory conditions.Acoustic emission activity was monitored using piezoelectric acoustic emission sensors,and the potential for accurate prediction of rock damage based on acoustic emission data was investigated. Damage localization was determined based on acoustic emissions generated from the critically stressed region as scattered events at stresses below and close to the strength of the material.

Flexural behavior of reinforced concrete beams with high performance fiber reinforced cementitious composites

This article presents an experimental study on the flexural performance of reinforced concrete(RC)beams with fiber reinforced cementitious composites(FRCC)and hybrid fiber reinforced cementitious composites(HFRCC)in the hinge portion.Beam specimens with moderate confinement were used in the study and tested under monotonic loading.Seven diverse types of FRCC including hybrid composites using fibers in different profiles and in different volumes are employed in this study.Companion specimens such as cylindrical specimens and prism specimens are also used to study the physical properties of composites employed.The moment?curvature,stiffness behavior,ductility,crack pattern and modified flexural damage ratio are the main factors considered in this study to observe the efficacy of the employed hybrid composites.The experimental outputs demonstrate the improved post yield behavior with less rate of stiffness degradation and better damage tolerance capacity than conventional technique.

Comparison of Distillation Methods of Mentha cordifolia Opiz, Essential Oil on Antibacterial Activity for Application Use in Animal Feeds

This study was conducted to evaluate the effect of different distillation methods of Mentha cordifolia Opiz. essential oil on antibacterial activity. The essential oils were isolated by water and steam, hydro, ethanol, and 3methanol： lethanol distillations. Moreover, we also compared the efficacy of these various distillations with commercial peppermint oil. Essential oils were tested in vitro against three pathogen bacteria species by sensitivity test include disc diffusion assay （DD）, minimal inhibition concentration （MIC） and maximal bactericidal concentration （MBC）. Escherichia coli, Staphylococcus aureus and Salmonella typhimurium were used in this investigation. The results showed that the water and steam distillation and 3methanol： lethanol under tested by DD assay was found to be effective against all the pathogenic bacteria, in which the zone of inhibition exhibited E. coil S. aureus and S. typhimurium were 9.67 ± 0.35, 11.67 ± 0.66, 18.0± 1.15 and 9.00 ± 0.05, 8.3 ± 0.35, 19.0 ± 0.00 ram, respectively. While the hydro and ethanol distillations did action to against only E. coli which the inhibition zones were 8.67 ± 0.66 and 8.67 ± 0.35 mm, respectively. However, the commercial oil was more effective against tested pathogenic bacteria than all M. cordifolia essential oil. In case of MIC and MBC assays, the results showed that all essential oil distillation methods posed antibacterial potential in which the water and steam distillation showed the lowest MIC and MBC values against E. coli, S. aureus and S. typhimurium. It is suggested that among all M. cordifolia essential oil extractions, water and steam distillation was found to be highly bactericidal as it has shown in lowest MIC and MBC values and high in growth inhibition zone diameter.

Impact Dynamics on Granular Plate

In this paper, a theoretical and numerical study on the impact of a rubber solid on the free surface of a granular plate is presented, showing a simulation of an aircraft wheel on impact with a flexible landing surface. This physical action, when we use a theological approach, becomes a fundamental parameter to investigate wear and tear, and consequently strength to micro and macro pavements failure. The study has developed initially from a microscopic point of view and subsequently on macroscale. The effects are strictly linked with material degradation associated with damage evolution. The problem is developed by energetic approach on an elastic-plastic element using the functional energy containing two contributions, bulk and surface. The model simulates the behaviour of flexible runway pavements during the landing phase.
