Evaluating Conservation Effectiveness of Nature Reserves Established for Surrogate Species:Case of a Giant Panda Nature Reserve in Qinling Mountains,China

Many nature reserves are established to protect the habitat needs of particular endangered species of interest but their effectiveness for protecting other species is questionable.In this study,this effectiveness was evaluated in a nature reserve network located in the Qinling Mountains,Shaanxi Province,China.The network of reserves was established mainly for the conservation of the giant panda,a species considered as a surrogate for the conservation of many other endangered species in the region.The habitat suitability of nine protected species,including the giant panda,was modeled by using Maximum Entropy(MAXENT)and their spatial congruence was analyzed.Habitat suitability of these species was also overlapped with nature reserve boundaries and their management zones(i.e.,core,buffer and experimental zones).Results show that in general the habitat of the giant panda constitutes a reasonable surrogate of the habitat of other protected species,and giant panda reserves protect a relatively high proportion of the habitat of other protected species.Therefore,giant panda habitat conservation also allows the conservation of the habitat of other protected species in the region.However,a large area of suitable habitat was excluded from the nature reserve network.In addition,four species exhibited a low proportion of highly suitable habitat inside the core zones of nature reserves.It suggests that a high proportion of suitable habitat of protected species not targeted for conservation is located in the experimental and buffer zones,thus,is being affected by human activities.To increase their conservation effectiveness,nature reserves and their management zones need to be re-examined in order to include suitable habitat of more endangered species.The procedures described in this study can be easily implemented for the conservation of many endangered species not only in China but in many other parts of the world.

Effect of Peaches, Pears and Green Tea on Plasma Lipids Profile and Antioxidant Content in Rats Fed High Sucrose Diet

The beneficial effects of feeding syrup of peaches and pears (peel and pulp) & green tea on the restoration of the changes produced by feeding high sucrose diet on plasma lipid profile, plasma antioxidant activity, and antioxidant enzymes in red blood cells (RBC) hemolysate were studied. High sucrose diet induced hyperlipidemia as manifested by significant (P ≤ 0.05) increases in the levels of cholesterol, triglycerides (TG) and low density lipoproteins (LDL) in plasma from 103.33 ± 1.8, 61.17 ± 0.48 and 26.6 ± 5.01 mg/dl to 136.67 ± 2.2, 81.3 ± 1.5 and 64.6 ± 6.5 mg/dl respectively. The high density lipoproteins (HDL) level was not significantly affected. TG levels in heart muscles increased significantly P ≤ 0.05 from the level of 194.14 ± 4.35 μg/g in the negative control to 269.72 ± 5.39 μg/g. Administration of fruits syrup and green tea resulted in a significant variable reduction in the elevated levels of cholesterol, TG and LDL and TG in the heart. Administration of sucrose resulted also in elevation of Malondialdehyde (MDA) in plasma from 5.06 ± 0.18 in the negative control to 14.81 ± 0.48 μmol/L in the positive control. This was also accompanied by reduction in the activities of supper oxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and a decrease in the concentration of reduced glutathione (GSH) in plasma, indicating lipid peroxidation. The activities of SOD, GSH-Px, CAT in the negative control were 8.96 ± 0.19, 315.67 ± 5.86, 209 ± 2.18 U/gHb respectively and were reduced significantly in the positive control to 4.7 ± 0.2, 273.83 ± 7.85, 207 ± 2.53 U/g Hb. There was a significant decrease in the level of total antioxidant status (TAS) in plasma from 1.45 ± 0.09 to 0.88 ± 0.09 nmol/L. However, no statistically significant changes were noticed in the concentrations of plasma total proteins and albumin. Intake of syrup of peaches and pears (peel and pulp) & green tea increased the level of TAS and GSH and decreased the level of LDL. The treatment also decreased significantly (P ≤ 0.05) the levels of plasma cholesterol, TG and heart TG levels. The activities of SOD and GSH-Px were increased following the treatment. It can be concluded that syrup of peaches and pears (peel and pulp) & green tea modulate lipid metabolism and enhance antioxidant status and in this respect green tea produced the best effect followed by peels of pears and peaches. The beneficial effect produced by fruits syrup and green tea may be due to their contents of phytochemicals.

Erosion of Grooved Surfaces by Cavitating Jet with Hydraulic Oil

To study the effect of impingement surface geometry, a cavitation erosion experiment was conducted using a submerged cavitating jet rig with hydraulic oil. The test setup comprised a test chamber with a long-orifice nozzle, a hydraulic pump with an electric motor, hydraulic auxiliaries, including valves, a cooler, a filter, a reservoir, and measuring instruments, including pressure gages and a thermometer. Hexahedral specimens made of aluminum alloy with flat and grooved surfaces and oblique angles were prepared. Hydraulic oil with a viscosity grade of 32 was used at 40&degC as the test fluid. The upstream absolute pressure was kept at 10.1 MPa and the cavitation numbers were set at 0.02 - 0.04. The results of this experiment yielded the following conclusions. The mass loss of the grooved specimens did not increase monotonically as the exposure time increased. The standoff distances at the maximum mass loss for the flat and grooved specimens were almost equivalent. The mass loss decreased as the oblique angle increased and the cavitation number increased, regardless of the presence of grooves. The surfaces were eroded in a ring-like region, but the region elongated as the angle increased. For the grooved specimens, the ridges on the ring were eroded, and when the directions of the grooves and the flow matched, the roots and flanks were severely eroded.

Vertical Profiles of Volatile Organic Compounds in Suburban Shanghai

As Volatile Organic Compounds(VOCs)are one of the precursors of ozone,their distribution and variable concentrations are highly related to local ozone pollution control.In this study,we obtained vertical profiles of VOCs in Shanghai’s Jinshan district on 8 September and 9 September in 2016 to investigate their distribution and impact on local atmospheric oxidation in the near surface layer.Vertical samples were collected from heights between 50 m and 400 m by summa canisters using an unmanned aerial vehicle(UAV).Concentrations of VOCs(VOCs refers to the 52 species measured in this study)varied minimally below 200 m,and decreased by 21.2%from 100 m to 400 m.The concentrations of VOCs above 200 m decreased significantly in comparison to those below 200 m.The proportions of alkanes and aromatics increased from 55.2%and 30.5%to 57.3%and 33.0%,respectively.Additionally,the proportion of alkenes decreased from 13.2%to 8.4%.Toluene and m/p-xylene were the key species in the formation of SOA and ozone.Principal component analysis(PCA)revealed that the VOCs measured in this study mainly originated from industrial emissions.

Engineering Intelligent Racing Concepts Using Design Research Methods

The automotive seat market is positioned to significantly grow over the next five years. Research into how sensor implementation in every day driver cars can enhance driver wellness is becoming increasingly popular and visible in the automotive seat industry. However, in the competitive race car industry,?drivers prioritize driving ability over wellness. To further examine this phenomenon, the Human-Machine Interaction?Lab at the Georgia Institute of Technology took a unique approach to developing strong use cases for implementing sensor technology to improve driving ability for race car drivers by combining qualitative and quantitative research data obtained through modern design research and planning methodology. Following a process relying heavily on user-centered design methods, the authors developed a business case concept?for?a sensor-based seat accessory that acts as a competitive racer’s?driving coach?that is able to identify the mechanics of braking, turning, and accelerating through pressure sensors in the driver’s seat pan surface. This technology allows drivers to precisely understand when and how hard to brake, turn, or accelerate out of turns, thus reducing heat times and financial burden for drivers.

The Optimization and Improvement of MapReduce in Web Data Mining

Extracting and mining social networks information from massive Web data is of both theoretical and practical significance. However, one of definite features of this task was a large scale data processing, which remained to be a great challenge that would be addressed. MapReduce is a kind of distributed programming model. Just through the implementation of map and reduce those two functions, the distributed tasks can work well. Nevertheless, this model does not directly support heterogeneous datasets processing, while heterogeneous datasets are common in Web. This article proposes a new framework which improves original MapReduce framework into a new one called Map-Reduce-Merge. It adds merge phase that can efficiently solve the problems of heterogeneous data processing. At the same time, some works of optimization and improvement are done based on the features of Web data.

Effects of Pressure during Preform Densification on SiC/SiC Composites

The nano-infiltration and transient eutectic-phase (NITE) method is one of the most attractive methods for fabrication of SiC and SiC/SiC composites. In the NITE method, preform densification is essential option for damage less near-net shaping technique. However, optimization of preform densification is insufficient yet. The objective of this study is to evaluate the effects of pressure during preform densification on SiC/SiC composites. The preform before preform densification has many pores in the inter-prepreg sheets. These pores were disappeared by preform densification. As the effects of pressure on preform, densification in the intra-fiber-bundle was improved due to increasing pressure. Flexural strength of the preforms with 1 MPa and 17 MPa indicated almost same value. The result suggested that increasing of pressure did not cause any change in fiber properties. In the effects of pressure on the composites, the composites with 17 MPa was exhibited improvement in bulk density and mechanical property, compared with that with 1 MPa.

AI for Supporting the Freedom of Drawing

Artificial intelligence(AI)has recently been developing rapidly in image processing and generation.AI is not only starting to take over repetitive and tedious tasks but is also involved in creative activities.Drawing is one of the areas with the greatest potential for collaboration between humans and AI.It is an important approach to express various information,but due to the lack of appropriate knowledge and skills,ordinary people without long-time training are unable to draw freely.Although there have been various attempts at human-AI collaboration in drawing,it is difficult for researchers to consider the wide variety of specific problems and develop univer-sal methods due to the openness,improvisation,and individuality of drawing.In this paper,we first analysed the contents of drawing and the general creation process in detail.Second,we have described a mechanism for using AI to enable people to regain the freedom of drawing collaboratively.Finally,we have developed a framework that describes methods for analysing specific problems and quickly finding solutions by building connections between the influencing factors in drawing,the demands of humans,and possible implementa-tion options.The framework also reveals a broad scope of possibilities for applying AI to support people in drawing.

Mitochondria-specific near-infrared photoactivation of peroxynitrite upconversion luminescent nanogenerator for precision cancer gas therapy

Gas therapy is emerging as a highly promising therapeutic strategy for cancer treatment.However,there are limitations,including the lack of targeted subcellular organelle accuracy and spatiotemporal release precision,associated with gas therapy.In this study,we developed a series of photoactivatable nitric oxide(NO)donors NRh-R-NO(R=Me,Et,Bn,iPr,and Ph)based on an N-nitrosated upconversion luminescent rhodamine scaffold.Under the irradiation of 808 nm light,only NRh-Ph-NO could effectively release NO and NRh-Ph with a significant turn-on frequency upconversion luminescence(FUCL)signal at 740 nm,ascribed to lower N-N bond dissociation energy.We also investigated the involved multistage near-infrared-controlled cascade release of gas therapy,including the NO released from NRh-Ph-NO along with one NRh-Ph molecule generation,the superoxide anion O_(2)^(⋅−)produced by the photodynamic therapy(PDT)effect of NRh-Ph,and highly toxic peroxynitrite anion(ONOO‒)generated from the co-existence of NO and O_(2)^(⋅−).After mild nano-modification,the nanogenerator(NRh-Ph-NO NPs)empowered with superior biocompatibility could target mitochondria.Under an 808 nm laser irradiation,NRh-Ph-NO NPs could induce NO/ROS to generate RNS,causing a decrease in the mitochondrial membrane potential and initiating apoptosis by caspase-3 activation,which further induced tumor immunogenic cell death(ICD).In vivo therapeutic results of NRh-Ph-NO NPs showed augmented RNS-potentiated gas therapy,demonstrating excellent biocompatibility and effective tumor inhibition guided by real-time FUCL imaging.Collectively,this versatile strategy defines the targeted RNS-mediated cancer therapy.
