The process of enzyme assisted extraction essential oil from the leaves and branches Vietnamese aromatic plant Cinnamomum cassia was studied optimized using a Box-Wilson central composite design consisting 05 independent variables (pH, temperature T, time τ, concentration Laccase, Cellic Htec2) two dependent (reducing sugar yield oil). Second-order polynomial equations were obtained for responses, which fitted well with experimental data. Optimal conditions found at pH = 5.2; T 440C; τ...
The utilization of unmanned aerial vehicles (UAVs) in high-rise firefighting operations is the right solution for reaching fire scene on high floors quickly and effectively. article proposes a quadrotor-type UAV model carrying launcher to launch missile containing extinguishing powders into fire. kinematic describing flight kinematics this built based Newton – Euler method when device normal motion at time launching missile. results from simulation testing validity show that variation...
Bài viết tập trung phân tích các nguồn vốn dùng để đảm bảo sinh kế của người H’Mông; Làm rõ thực trạng hoạt động H’Mông tại xã Rô Men, huyện Đam Rông, tỉnh Lâm Đồng. Kết quả nghiên cứu đã chỉ rõ, so với trước khi di cư, lực hộ gia đình Men được cải thiện, đặc biệt là tự nhiên và vật chất. Bên cạnh chủ đạo trồng trọt thì khác như buôn bán, chăn nuôi đang dần hình thành bắt đầu phát triển. Tuy nhiên, tài chính con còn nhiều thiếu hụt. Từ kết cứu, bài khuyến nghị một số giải pháp triển bền vững...
Red mud is a highly alkaline solid waste from the Bayer process for aluminum production. reservoirs are usually considered as potential environmental risk. The treatment of red costly due to lack an effective and economical technology. On other hand, main components Fe2O3, Al2O3, SiO2, Na2O, which could be employed promising precursor preparation various nanomaterials. In this study, we prepared activated by thermal acid method applied it adsorption H2S in air. was under different...
The aim of this study is to examine the relationship between service marketing mix, tourist satisfaction and loyalty. participants are domestic tourists choosing Con Phung resort in Ben Tre province as a destination. scales were assessed by Cronbach's Alpha coefficient, exploratory factor analysis, confirmatory analysis hypotheses tested through structural equation model. results research confirm that all mix’s elements (price, product, place, promotion, process, people, physical...
Nhien liệu sinh học đang la xu thế mới của giới trong việc tim kiếm nguồn nang lượng thay cho từ hydrocacbon dần cạn kiệt. Trong khuon khổ bai bao nay, chung toi sử dụng quy hoạch thực nghiệm để gia trịt ối ưu cac thanh phần tham qua trinh thủy phân cellulose sao đạt hiệu quả cao nhất.
Based on data of II industrially developed countries, the experimental statistical modeldescribing a relation between solid waste rate treated in sanitary landfills and four factors:country area, population, GOP/person waste/person per year. This model was used tocalculate for Viet Nam period ofindustrialization. The main factor is finding equastion isy = 3,0819X4, - 569,527,% which l4 from 185 to 217 kg/person.year.The method gives more accurate results when treated.
Abstract Scientific literature has witnessed an alarming upsurge in the utilization of tortured phrases within scholarly articles. These special cast doubt on credibility research, irrespective underlying rationale. Therefore, we introduced Tal- bots, which facilitates identification and categorization sentence clusters. Our investigation thoroughly assessed 8,792 academic publications, including books articles, characterized by their deployment odd incomprehension language, such as...

In this study, the unpretreated sugar cane bagasse was milled to a particle size of 0.5 – 1 mm and be used as material for bioconversion into fermentable sugars by using an enzyme cocktail acted synergistically. Experimental planning optimize conversion through assessment analysis individual parameter. As result, optimal condition enzymatic reducing product are at pH = 5, 400C, 48 h incubation in rate (Cell/Xyl, AltFAE, XpoAE) substrate (bagasse meal) is 3.1. From above application,...
Biến đổi khí hậu (BĐKH) đã và đang là một trong những thách thức lớn nhất với nhân loại. BĐKH tác động đến hầu hết các lĩnh vực của nền kinh tế từ nông nghiệp, lâm thủy hải sản xuất dầu khí, điện vận tải biển... Trồng trọt ngành chịu ảnh hưởng trực tiếp nặng nề do BĐKH. Bài viết này góp phần nghiên cứu đánh giá bước đầu về số biểu hiện ở thành phố Đà Lạt nó hoạt trồng tại địa bàn cứu, cũng như cách mà hộ gia đình nơi đây ứng phó Trên cơ sở đó khuyến nghị giải pháp nhằm nâng cao năng lực thích trọt.
Abstract For prediction of tensile strength combine aged NR/CR blends, samples with ratios 100/0, 95/5 and 90/10 were subjected heat aging at various temperatures, namely 100, 110 120°C, each for 22 h, followed by dynamic loadings to 140 % frequency 300 cycles/min. Then the strengths defined. Based on obtained experimentally values experimental statistical model was built using FORTRAN language. The result in equation NR blends low CR (not higher 10 %) contents. This seems have fine...
