Hydrothermal carbonization (HTC) of lawn grass was carried out at 200 °C and 240 °C for 30 to 180 min. The chemical, energetic, and structural characteristics of HTC solid residues were investigated. Results from HTC experiments indicate that solid mass yield of all solid residues was 31 to 50%. The hydrogen/carbon (H/C) and oxygen/carbon (O/C) atomic ratios of all solid residues were 1.17 to 1...

SC-FDMA suffers from high Peak-to-Average Power Ratio (PAPR) problem, which restricts its usage in some applications. In this paper, a joint Discrete Cosine Transform (DCT) and hyperbolic tangent companding (HTC) technique has been studied in order to minimize the effects of the peak-to-average power ratio of the SCFDMA System. The proposed scheme utilizes a DCT rather than the conventional dis...

Hydrothermal carbonization (HTC) of carbohydrate is an interesting candidate for the preparation of carbon materials, as it provides an easy, inexpensive and environmental friendly route. However, it is difficult to prepare porous carbon materials by a straight HTC process. Herein, the solubilising technology of micelles was introduced to direct the HTC of fructose by using an amphiphilic block...

Existing instance segmentation models mostly pay less attention to the targeted characteristics of ships in synthetic aperture radar (SAR) images, which hinders further accuracy improvements, leading poor performance more complex SAR image scenes. To solve this problem, we propose a hybrid task cascade plus (HTC+) for better ship segmentation. Aiming at specific task, seven techniques are propo...

In this paper, we explore some algebraic properties of linear structural equation modelsthat can be represented by an HTC-identifiable graph. particular, prove that all mixedgraphs are if and only the regression coefficients recovered fromthe covariance matrix using straightforward algebra operations. We also find a set ofpolynomials generates ideal encompasses equality constraints modelon cone...

BACKGROUND The authors piloted an HIV testing and counseling (HTC) approach using respondent-driven sampling (RDS), financial incentives, and persons living with HIV infection (PLHIV). METHODS Eligible participants were aged 30-60 years, African American or black, and residents of Oakland, CA. Participants were tested for HIV infection and asked to refer up to 3 others. The authors compared t...

OBJECTIVES To evaluate the feasibility (population reached, costs) and effectiveness (positivity rates, linkage to care) of two strategies of community-based HIV testing and counselling (HTC) in rural Swaziland. METHODS Strategies used were mobile HTC (MHTC) and home-based HTC (HBHTC). Information on age, sex, previous testing and HIV results was obtained from routine HTC records. A consecuti...

A two year field experiment was carried out to evaluate the effects of three row and eight row seeding on the total phenolic compound (TPC), total flavonoid content (TFC), hydrolyzed (HTC) and condensed tannin (CTC), antioxidant activity (ABTS assay), protein content and soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) in the extracts of lentil (Lens culinaris L.) and grass pea (La...
