Background and Purpose: Burn injuries are prone to infection caused by bacteria, fungi, or other pathogens. Fungal wound infection usually has non-specific clinical symptoms.Nevertheless, in some cases, the fungal burden is so substantial that can easily be seen by the naked eyes, but this phenomenon has rarely been reported with Fusarium. Case report: A 53-year-old patient with severe burn injury was admitted to the intensive care unit of the National Hospital of Burn, Ha Noi, Vietnam. His wound was dressed with a traditional herbal product before the hospital admission. On the 5th day after the admission, some white patches suspected of fungal colonies appeared on burn lesions where the herbal medicine was placed. Histological examination (Periodic acidSchiff) and culture of biopsy samples taken from those lesions revealed fungus that was identified as Fusarium equiseti after analysis of the internal transcribed spacer and D1/D2 region of the large subunit of the 28S rDNA. The isolated strain showed susceptibility to voriconazole but resistance to fluconazole, itraconazole, caspofungin,and amphotericin B in vitro. The patient received aggressive treatment, including IV voriconazole (400 mg daily from day five); however, he could not recover. Conclusion: Fusarium should be suspected in burn patients with white patches on lesions. Antifungal susceptibility testing is important since multidrug resistance is common among Fusarium strains.

Background: Human toxocariasis is prevalent in many countries but this disease has been rarely reported from Vietnam. We aimed to investigate the clinical and laboratory findings and assess possible association between these findings in patients with toxocariasis in Vietnam. Methods: A prospectively study, between October 2017 and June 2019 was performed involving 120 toxocariasis patients at Medic Medical Center, Ho Chi Minh City, Vietnam. The diagnosis of toxocariasis was established based on clinical, laboratory (eosinophilia, raised IgE concentration) and serological (positive Toxocara IgG ELISA test) evaluation as well as the exclusion of other helminthic coinfection. Results: The most frequently reported manifestation was of skin (n = 93, 77.5%), including urticarial (n= 69, 57.5%) followed by neurologic, gastrointestinal and pulmonary signs/symptoms. Hepatic involvement occurred in 8.3% of the patients. No significant relationship between clinical findings and laboratory parameters was found except the higher values of eosinophil count and IgE concentration among patients with liver involvement. There was a significant relationship between eosinophil count and IgE concentration (r=0.389, P

Objectives Human toxocariasis is a widespread zoonosis for which a chemotherapy decision and therapy effectiveness are difficult to determine. We aimed to investigate the kinetic profile of clinical and laboratory findings and treatment outcome of patients with toxocariasis in Vietnam. Methods The prospective study was conducted between October 2017 and June 2019. The diagnosis of toxocariasis was established based on clinical, laboratory (eosinophilia, raised IgE concentration) and serological (positive Toxocara IgG ELISA) evaluation as well as the exclusion of another helminthic coinfection. The patients were followed up after seven days, then one, three, and six months after chemotherapy by thiabendazole. Results The study involved 80 patients with a mean age of 41.6 ± 15.2 years of whom 58.8% were female. At three and six months after chemotherapy, most patients demonstrated resolution of clinical signs and symptoms, eosinophil count and IgE concentration but not in the proportion of IgG seropositivity. Skin lesions and eosinophilia resolved earlier than the other symptoms (one month after treatment). About four-fifths of the patients were "cured" after three and six months of follow-up. 33.8% showed side effects to thiabendazole therapy but no severe events were reported. The most common adverse reaction was neurologic symptoms followed by gastrointestinal or skin manifestations which lasted as long as 4 days. Conclusions In toxocariasis patients, cutaneous manifestations and eosinophilia resolve more rapidly than other clinical and laboratory findings while IgG titre has a very slow kinetic after therapy. Thiabendazole seems to be a potential alternative for the treatment of human toxocariasis.

Research on formulation of nanosilver-infused cream was carried out at the Institute of Environmental Technology and the effects of this cream in prevention and treatment of mastitis in dairy cows were assessed at Bavi Cattle and Forage Research Center. Cream with 0.4% carbomer was infused with silver nanoparticles for high uniformity and long-term stability. At concentrations of 50–250 ppm, nanosilver-infused cream proved to be effective against mastitis pathogens such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa. Nanosilver cream at concentrations of 150 ppm had the best effect on clinical and subclinical mastitis prevention in dairy cows. Combining nanosilver cream with ceftiofer antibiotic achieved excellent treatment rate, up to 93.33%. For prevention of dairy mastitis, silver cream can be used at a concentration of 150 ppm 15 days before calving and for the whole milking period. Using nanosilver cream in combination with antibiotics led to highly effective mastitis treatment.

Gradient doping ensures uniform transverse gain in an edge-pumped multislab pulsed amplifier, and a 1D iterative method is developed to generate the proper doping profile. Our investigations show that uniform gain under short pump duration tp = 0.25 ms can be readily achieved, where the modulation of the gain distribution is lower than 1.05 even if the diagonal transverse gain-length product (DTGLP) increases up to 5. For tp = 1.0 ms, comparable modulation of the gain distribution is achieved for a much lower DTGLP value of 2.3. To extend the DTGLP range for long pump duration, a modified 1D iterative method with an effectively “shortened” lifetime of the active ions is developed. With the modified method, the gain uniformity for both pumping conditions is greatly improved, and specifically, the DTGLP increases from 2.3 to 3.0 for tp = 1.0 ms. In addition, degradation of the gain uniformity resulting from deviations of the doping concentration is discussed. The deviations should be at least lower than 1% and 5% for tp = 1.0 ms and tp = 0.25 ms to maintain the gain uniformity, respectively. Our investigations might provide a useful way to design the amplifier with uniform gain in the beam aperture of a high average power pulsed laser.Gradient doping ensures uniform transverse gain in an edge-pumped multislab pulsed amplifier, and a 1D iterative method is developed to generate the proper doping profile.

As an important environment-friendly new energy with low carbon emission, shale gas has attracted very much attention around the world. Based on such characteristics as the geologic histories, the sedimentary and structural settings, and the shale gas accumulation mechanism and distribution patterns, the areas with shale gas accumulation in China can be divided into four regions which correspond to the tectonic plates by and large. Shale is very developed in each geologic period, and the shale formations include Sinian, Paleozoic, Mesozoic and Cenozoic. They are widely distributed in the hydrocarbon basins formed in different eras, the areas where deposits are remained after complex tectonic movements, or the outcrop areas. In terms of basin types, craton, foreland and rift (faulted) basins all contain shale; in terms of sedimentary facies, there are diverse facies of shale deposits, including both the marine shale with good-very good TOC in South China and the organic-rich lacustrine and marine-continental transitional shale in North China. Compared with North America where shale gas resources were generated, accumulated, and have been developed commercially, China also has suitable geologic structural and depositional conditions favoring the generation, accumulation and distribution of shale gas. It is preliminarily estimated that there are abundant shale gas resources in China. The total shale gas resources are about 15−30×1012m3, and the mid-value of the shale gas resources is 23.5×1012m3, close to the mid-value of 28.3×1012m3 in the U.S. In a word, shale gas is widely distributed in China with good exploration and development potential. Nonetheless, shale gas exploration theory and target assessment approaches should be established in line with China's complicated geological and structural conditions, and also the properties of shale gas reservoirs in different regions. Drilling and production technologies applicable to the geologic characteristics of China's shale formations should be researched and developed to facilitate efficient shale gas production in China.

a new semi-supervised classification method is proposed by combining airborne LiDAR (Light Detection And Ranging) data with registered aerial images. Firstly, the algorithm filtered LiDAR data into ground points and non-ground points that were further partitioned into small planar regions based on local attribute estimation. Then these planar regions will be used as initial classes to obtain initial samples that were used as training samples in aerial images to perform classification process with the maximum likelihood. The proposed method can also revises misclassified building regions by using shape index. Every single LiDAR point can be labeled by comprehensively considering information like filtering results, intensity from LiDAR data and spectral features from aerial images. The experiment shows that the proposed can improve the classification accuracy of LiDAR points cloud in complicated urban.

The trust research is a core content in the field of e-commerce research in C to C environment. In the course of network trust formation, the initial trust is most important. By introducing the content of initial trust, the paper established a three-stage dynamic concept model of consumer initial trust formation in C to C environment. Site quality trust, site transactions safety trust and seller reputation trust are the major initial trust factors in the formation of consumer initial trust. Based on this model, the paper gives some strategies to C to C e-commerce sites and sellers to establish consumer trust, so that to give some useful inspiration to the sites and the seller's future development.

For the first time, a novel hybrid SOI/bulk CMOS technology with 20nm gate length and low-leakage 1.3nm thick SiON gate dielectric has been developed for advanced SOC applications. 26% (for N-FET) and 35% (for P-FET) improvements of intrinsic gate delay (CV/I) at low gate leakage of 20-40A/cm/sup 2/ have been achieved over previous leading-edge 45nm node version, while maintaining the same sub-threshold leakage (100nA//spl mu/m). 10 times reduction of the leakage can be further modulated by a virtual back-gate control. Fine patterning with line pitch of 90nm by immersion lithography is demonstrated, which features 0.183/spl mu/m/sup 2/ 6T-SRAM cell for 32nm node on-trend scaling.

The first 45nm node planar-SOI technology has been developed with 6T-SRAM cell of 0.296 /spl mu/m/sup 2/. An adequate static noise margin of 120mV is obtained even at 0.6V operation. Fine patterning with line pitch of 130nm and contact pitch of 140nm by optical lithography is demonstrated. Transistors with 30nm gate length and 27nm slim spacer operate at 1V/0.85V with excellent drive currents of 1000/740 and 530/420 /spl mu/A//spl mu/m for N-FET and P-FET, respectively. The P-FET current is the best reported so far.

A new nanowire FinFET structure is developed for CMOS device scaling into the sub-10 nm regime. Accumulation mode P-FET and inversion mode N-FET with 5 nm and 10 nm physical gate length, respectively, are fabricated. N-FET gate delay (CV/I) of 0.22 ps and P-FET gate delay of 0.48 ps with excellent subthreshold characteristics are achieved, both with very low off leakage cur-rent less than 10 nA/ /spl mu/m. Nanowire FinFET device operation is also explored using 3-D full quantum mechanical simulation.

In this paper, the mechanical stress effect of SOI MOS devices was analysed. The width dependence of stress effect and drain current shift were evaluated.

An integrated scheme of defect physics and defect chemistry was developed to study the electronic and electrical properties of CuInSe2. We found that the Madelung energy and relaxation process play significant roles in the defect physics formulation, and some computed data of defect concentrations and the corresponding carrier concentrations using our new scheme are presented.

A 65 nm node strained SOI technology with high performance is demonstrated, providing drive currents of 1015 and 500 /spl mu/A//spl mu/m for N-FET and P-FET, respectively, at an off-state leakage of 40 nA//spl mu/m using 1 V operation. The technology employs an aggressively scaled slim spacer of 30 nm width to amplify stress benefits for performance improvement, and to reduce by 10-20 % the layout area for SRAM-cell-like circuits, while maintaining excellent hot carrier immunity and well-controlled short-channel effects. For the first time, we demonstrate that FinFET devices, implicitly implemented in this technology, offer a 8-15 % higher inverter speed compared to planar SOI devices at the same drive current.
