The Process of Tiger Disappearance in Guizhou

In this paper,the authors collected officially published literature on the South China tiger(Panthera tigris amoyensis)in Guizhou from 1900 to 1980,from which we extracted information on its historical distribution and population size,and collected data on the tiger skin trade after 1950,the change in subtropical broad-leaved evergreen forest cover,and demographic data in the relevant databases.GIS mapping was used to visualize the distribution range of the South China tiger in Guizhou Province during the period 1900–1980 and to discuss the history of its disappearance in Guizhou and its driving factors.The results show that in 1900,the South China tiger was distributed throughout 82 cities and counties in nine prefectures and municipalities in the province;the number of documented South China tiger distribution sites in 1900–1950 decreased to 48 compared to 1900;the number of counties with South China tigers in 1950–1980 further decreased and became extinct in some areas;and in the 1990s,the South China tiger became extinct in the wild in Guizhou.The main reasons for the extinction of the South China tiger in the wild in Guizhou are:on the one hand,with the socio-economic development of Guizhou Province,the population has increased dramatically,the magnitude of the demand for natural resources has increased,and in order to satisfy this demand,human activities,such as coal mining and clearing of mountains for planting,have been intensified,resulting in the reduction of the coverage rate of the subtropical broad-leaved evergreen forests,which has resulted in the extreme loss of the habitat of the South China tiger;on the other hand,the insufficient protection efforts and protection measures for this species in the country before the 1980s,which were subjected to anthropogenic hunting,were also factors leading to the extinction of this species in the wild in Guizhou Province.As a big cat at the top of the food chain,the distribution of the South China tiger can reflect the history of the natural environment in the region.By analyzing and discussing the distribution history of the South China tiger population in Guizhou Province,the significance of this case is to provide a scientific basis for the future conservation of biodiversity and the development of ecological restoration measures in the karst mountains of southern China.

Who is in the Lower Reaches,Who Suffers Disasters?——Take Minqin County,a Disappearing Oasis as a Case

Minqin Oasis is located in the lower reaches of the Shiyanghe River Basin, northeast of the Heixi Corridor, at the middle of the Silk Road. Because of the its existence, Badain Jaran Desert and Tengger Desert cannot converge and develop in the south. It has always been an important green barrier to guarantee the eco-security of Hexi Corridor and the Silk Road for thousands of years. But in recent decades, Minqin Oasis is becoming smaller and the desert is becoming larger. Many people, especially the governmental officials in the lower reaches think that the upper and middle reaches have robbed the lower reaches of water resources, and caused insufficient water usage and the deteriorated eco-environment, in the lower reaches, However, the governmental officials in the upper and middle reaches claim that the whole river basin should take the upper and middle reaches as the key regions to develop economy. To address the above argument, we analyze the reasons why Minqin Oasis is disappearing, and find that there are two main factors. One is the quick development of population and economy in the upper and middle reaches; the other is the rapid development of population and economy in the lower reaches. The two factors both have great effect on the water utilization for eco-environment in the lower reaches. So Minqin Oasis is disappearing not only because of the upper and middle reaches but also because of the growth of population and economy itself. The lower reaches should not completely blame the upper and middle reaches. The upper and middle reaches should also pay more attention to the eco-environment in the lower reaches. The whole river basin should develop a harmonious and sustainable relationship among the upper, middle and lower reaches.

DISAPPEARANCE OF INTERFACES FOR DEGENERATE PARABOLIC EQUATIONS WITH VARIABLE DENSITY AND ABSORPTION

Reading Text Under Normal and Disappearing Presentation Conditions

In this article I discuss data from a series of experiments in which readers’ eye movements were recorded as they processed sentences in which each word disappeared or was masked 60ms after fixation onset. We used this paradigm to investigate whether we could induce a gap effect during reading, and how visual and linguistic factors affected eye movements under these conditions. The data showed that no gap effect occurred in our experiment. Overall reading times were the same under normal and disappearing presentation conditions. However, readers did adopt a strategy of making fewer but longer fixations when the text disappeared than when it did not. Additionally, clear frequency effects occurred regardless of whether the text was presented normally or disappeared. This finding indicates that while the visual uptake of information is important, cognitive processes associated with the lexical identification of words are a primary influence on when readers move their eyes during reading. The findings are taken to support the E-Z Reader model of eye movement control.

Disappearance of unaffected motor cortex activation by repetitive transcranial magnetic stimulation in a patient with cerebral infarct

The ipsilateral motor pathway from the unaffected motor cortex to the affected extremity is one of the motor recovery mechanisms following stroke （Jang, 2011）. Because stroke patients who had shown recovery by this mechanism usually showed poorer motor function, compared with patients who showed recovery by other mechanisms, several researchers have considered this mechanism as a maladaptive plasticity （]ang, 2013）.

Prosperity and Disappearance of Introduced Fishes in Xiangmoshan Reservoir

In order to enhance the resources, some fishes were introduced into Xiangmoshan reservoir. The introduced fishes consisted of different ecotypes such as silver carp （Hypophthahnichthys rnolitrix （Cuvier et Valenciennes））, big head （Aristichthys nobilis （Richardso）） and lake herring （Coregonus clupeaformis （Mitchill）） that were plankton feeders, common carp （Cyprinus carpio Linnaeus） and crucian carp （Carassius auratus gibelio） belonging to the polyphagia, and also the non-native predator Walleye （Stizostedion vitreum （Mitchill）） and big mouth （Silurus soldatovi rneridonalis Chen）, et al. Among there were not only the cool water fish Peled （Coregonus peled （Gmelin））, but also the warm water fish big mouth. The introduction of non-native fishes resulted in ecosystem changes of the reservoir and some native fishes had gone to decrease their population sizes or been in the condition of depopulation such as Opsariichthys uncirostris arnurensis （Berg）, Rhodeus sericeus （Pallas） and Silurus asotus （Linnaeus）. The native common carp had disappeared after the introduction of non-native species. Roach （Rutilus rutilus lacustris （Pallas） had been thriven for one or two generations after its introduction and immeidiatly disappeared. Silver fish （Protosalanx hyalocranius （Abbott））, Lake herring （Coregonus clupeaformis （Mitchill）） and Walleye （Stizostedion vitreum （Mitchill）） died several years after the introduction, so most of the introduced species has passed out of existence. Via many years introduction of different fishes, composition of species and the structure of the population in the reservoir had been changed obviously. It was necessary to further estimate whether the ecosystem of the reservoir had been damaged.

Ruminal in situ disappearance kinetics of six nutritive ingredients in leaves and stems of young tetraploid black locust in growing steers

Tetraploid black locust （Robinia pseudoacacia） is a woody plant with larger leaves and richer nutritional content than normal diploid black locust, with greater biomass and wider adaptability than herbaceous plant forage. However, currently no stock- breeders have adopted it as a major forage in China and other countries for a lack of information on the evaluation of nutritional ingredients of leaves and stems of young tetraploid black locust （YTBL） by in situ digesting tests. The objectives of this study were： 1） to assess the nutritive value of YTBL that bourgeoned from root stumps in the spring by determining the ruminal in situ disappearance kinetics of dry matter （DM）, organic matter （OM）, crude protein （CP）, ether extract （EE）, neutral detergent fiber （NDF） and acid detergent fiber （ADF） from leaves, stems and a mixture of both leaves and stems （MLS） of YTBL; 2） to compare these kinetic estimates with those of Leymus chinensis, a widely used ruminant forage in China. All samples were evaluated in situ by using five ruminally cannulated crossbred steers （550±22.7 kg BW）. The results of 48 hours, the representative incubation period, indicate that in situ disappearance rates of DM and OM in YTBL leaves, stems and MLS are on average about 40% and can attain the level of digestibility of L. chinensis. In situ disappearance rates of leaves, stems and MLS of YTBL for CP and EE were 41% and 58% respectively, rates higher than those of L. chinensis. But the disappearance rates of NDF and ADF were, on average, respectively 30.62% and 24.89% and lower than those ofL. chinensis. By analyzing synthetically all of our results it could be inferred that MLS of YTBL offers effective ruminal degradability of DM, NDF, ADF, CP, EE and OM, similar to the nutrients of L. chinensis. This supports our contention that the YTBL leaves, stems and MLS are suitable feed for those ruminants requiring high levels of nutrients, such as dairy cows and Boer goats, instead of plant forage, which is decidedly lacking in some parts of the world.

Influencing factors for the disappearance of hemispatial neglect in patients during acute stroke

BACKGROUND： Some researches are proved that early sitting balance and body motor control performed on patients with stroke and hemiplegia is related to functional prognosis. For patients with hemispatial neglect （HSN） dunng acute stroke, whether HSN disappearance is related to those trainings or not should be further studied. OBJECTIVE： To analyze the correlation between HSN disappearance and related intervention of patients during acute stroke. DESIGN ： Case analysis SETTING ： Department of Neurology, First Affiliated Hospital of Guangxi Medical University PARTICIPANTS： A total of 21 patients with stroke were selected from the Department of Neurology, the First Affiliated Hospital of Guangxi Medical University from May 2005 to March 2006. Diagnosis criteria： ① Stroke was diagnosed by CT and MRI; ② Diagnosis was coincidence with HSN evaluation criteria; ③ All cases were consent. Exclusion cnteda： Patients who had poly-focus, conscious disturbance, severe amentia and hard communication combined with aphasia were excluded. A total of 12 males and 9 females were included, and the mean age was （68±10） years. Among them, 14 patients had cerebral infarction and 7 had cerebral hemorrhage. METHODS： Disappearance and existence of HSN were analyzed with HSN evaluation criteria： body agnosia, left and nght agnosia, maintenance of supine position, place of things, sitting up straight, center of line measured by eyes, and cutting 30 lines with paring method, Items mentioned below belonged to HSN disappearance： ① without body agnosia; ② without left and nght agnosia; ③ be able to maintain supine position; ④ knowing place of things; ⑤ sitting up straight by one＇s own; ⑥ be able to measure the center of line by eyes; ⑦ be able to cut 30 lines with paring method. However, only one item belonged to HSN remnant; but only one item belonged to HSN remnant. Numbers of patients who were of body agnosia, left and nght agnosia and difficult maintenance of supine position were observed during acute period （within 1 week） and recovery period （at 2 weeks after onset）. Related factors with HSN disappearance contained time of physiotherapy, duration of sitting training （sitting in bed and near bedside： heels fallen to ground, feet loaded heavies, center of gravity located at middle line, head raised towards frontage） and hospitalized time. However, control group was not set up.Measurement data were expressed as Mean＋SD and compared with ttest; enumeration data were compared with Chi-square test and Mann-Whitney Utest. P 〈 0.05 was regarded as significant difference. MAIN OUTCOME MEASURES： ① HSN disappearance; ②Numbers of body agnosia, left and right agnosia and difficult maintenance of supine position;③ Correlation among therapeutic time, sitting-training time and hospitalized time. RESULTS： All 21 patients were involved in the final analysis. ① HSN disappearance： Among 21 cases, 2 patients had right HSN disappearance, 19 left HSN disappearance, 8 （38%, 8/21） HSN disappearance, and 13 （62%, 13/21） HSN remnant. Among 8 patients of HSN disappearance, symptoms of 4 cases lasted for 7 days and that of another 4 lasted for 8-12 days. ② Evaluation of HSN disappearance at various phases： Within 1 week, 19% （4/21） HSN patients had body agnosia, left and right agnosia; during recovery period, body agnosia of 20 cases was disappeared and that of 1 case was still survived. Within 1 week, cases with difficult maintenance of supine position were 67% （13/21）, but 43% （17/21） during recovery period. ③ Analysis of effective factors on HSN disappearance and related intervention： At acute phase, HSN disappearance through sitting training lasted for （2.5±1.3） days, and remaining HSN symptoms were relieved for （5.0±3.7） days. There was significant difference between them （ x^2= 3.96, P = 0.039）. The hospitalized time of patients with HSN disappearance and HSN remnant was （17.6±10.4）, （16.2±4.9） days, but there was no significant difference between them （x^2 = 1.41, P = 0.679）. Physiotherapy time of patients with HSN disappearance and HSN remnant was （11.1 ±7.5）, （11.4±4.1 ） days, but there was no significant difference between them （x^2 = 1.05, P = 0.894）. CONCLUSION： Early sitting training may play a possible role in HSN symptom disappearance of patients with stroke.

Kinetics of the thermal disappearance of radicals formed during the radiolysis of L-α-anhydrous asparagine

The EPR spectra of gamma irradiated samples at room temperature, shown the presence of three types of paramagnetic centers. A possible mechanisms of formation for the three radical species is suggested, based also on literature data. The kinetics of the disappearance of radicals during thermal annealing indicated a complex mechanism.

Zhang Heng’s Seismoscope(3):Disappearance & Scientific Value

The ancient idea of Heavenly Punishment confused natural phenomena with social issues,which resulted in Zhang Heng’s tragedy in his later years and seismoscope. The instrument might have been lost in the end of the Eastern Han Dynasty. A series of extremely serious chaotic social events caused by war took place,such as a fire in Luoyang,forging coins by destroying copper wares,relocation of the capital,sharp population decrease,and the destruction of the Ling Observatory. Zhang’s scientific thought and successful practice had played an important role in ideological enlightenments at the primary stage of modern seismology at the end of the nineteenth century. There is a glorious course of"innovation—inheritance—re-innovation"of scientific and technical development from the inception Zhang Heng’s seismoscope to the modern seismograph invented by Milne,et al.
