Research ArticleOpen accessEvery word in the titleStudy on the Synergistic Treatment of Soil Fumigation and Biocontrol Bacteria for the Prevention and Control of Root-Knot Nematodes in Facility SoilLijin Qin, Yingmin Hu et al.Years of continuous cropping have led to the inability to cure root-knot nematode disease. In this study, soil fumigation was used before tomato planting to study the decline rate and the effect of root-knot nematode population control after soil fumigation. During the experiment, "Wofengkang" organic sulfur soil fumigant was used. A constant temperature drying oven was used to artificially simulate … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 26 Sep 2024 · 4,843 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBacterial Diversity Change after Soil Fumigation and its Effect on the Population of Root-Knot NematodeMin Shan, Lihong Liu, Jing Chen et al.In order to explore the effects of soil fumigation on its bacterial diversity and root-knot nematode populations, the greenhouse tomato soil with root-knot nematode disease was fumigated during the summer idle period. This experiment used the high-efficiency organic sulfur soil fumigation treatment "Wofengkang"300 kg/hm2 to fumigate on the greenhouse tomato soil with a root-knot nematode incidence rate of 64.37% and … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 2 Mar 2022 · 5,978 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFolding of Trefoil Knot and its GraphM. El-Ghoul, A. I. Elrokh, M. M.A. ShamiriIn this study, we introduce the effect of the folding, conditional folding, retraction and conditional retraction on trefoil knot and its graph. We introduce the sheeted trefoil knot and the folding and retraction of this type and present the limit of foldings. We study how to obtain the types of link graph by adjacency matrix for any number of vertices … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvey and Distribution of Plant Parasitic Nematodes on Tomato at Baruasagar in Jhansi (India)Abha Sachan, Rajesh Kumar Pandey, Shailendra Kumar et al.Tomato (Lycopersicon esculentum) is an important high-value vegetable crop and acts as a natural medicine that alleviates the risk of a condition such as cancer and cardiovascular disease. Plant parasitic nematodes are obligate biotrophic feeders that cause the most devastating phytoeconomic damage to tomato cultivation across the globe. Their infection may lead to a spectrum of disorders like stunting, necrosis … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 10 Jan 2024 · 6,822 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuture Medicine Services RoboticsRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion T. PetrescuIt is an entry technique in use recently, albeit in selected centers and represents a further step in the field of minimally invasive surgery. Basically it has the same indications but, at present, is reserved for selected patients. Compared to traditional video-assisted surgery presents some important differences. The surgeon is physically distant from the operative field and sits at a … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 26 Nov 2016 · 8,893 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Smooth Support Vector Machine and Its Applications in Diabetes Disease DiagnosisSanti Wulan Purnami, Abdullah Embong, Jasni Mohd Zain, S. P. RahayuProblem statement: Research on Smooth Support Vector Machine (SSVM) is an active field in data mining. Many researchers developed the method to improve accuracy of the result. This study proposed a new SSVM for classification problems. It is called Multiple Knot Spline SSVM (MKS-SSVM). To evaluate the effectiveness of our method, we carried out an experiment on Pima Indian diabetes … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnmanned Mini Boat Design for the Camera Bearer of the Vannamei Shrimp Monitoring DeviceBambang Sampurno, Mashuri, Arif Abdurrahman et al.The research of vanamei shrimp counting has been developed by numerous scientists, but image processing in actual pond didn’t progress well. The used of image processing based on the way of capturing the image from the shrimp which located on the bottom of the pond. The way to capture the image was to put a camera under the deck of … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 9 Mar 2018 · 8,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Genetic Optimization for Design of Small Diesel-Battery SubmarineWisnu Wardhana, Meitha SoetardjoDesign of a Small Diesel-Battery Submarine (SDBS) has been carried out using Multi-Objectives Genetic Algorithm optimization combined with Analytical Hierarchy Process to meet the operation requirements. The objective attributes for this optimization are cost and effectiveness. The product of this optimization is a series of cost-effectiveness frontiers in the scattered graph which are used to select alternative designs based on … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 18 Feb 2017 · 7,824 accessesView PDFCite
