Abstract: The combustion engines are widely used in the daily life of people, in cars, we find them with greater emphasis, and currently hybrid engines and electric motors are being used. In this analysis, one of the important factors for the failure of combustion engines is the temperature, for which cars have cooling systems, through the use of radiators and coolant-based systems. In this work we present a methodology for the analysis of the state of the components of the combustion engine system in cars, through the use and analysis of thermal images, for which it is necessary to identify the zones or control points depending on the model and type of engine and car, The analysis procedure requires a thermal camera, the results presented are related to the comparison of an optical and thermal image, in order to locate the control point, the method can be applied by mechanics, maintenance personnel and car drivers themselves, to analyze the condition of their car.

Abstract: Drowning is a dramatic situation, with very serious consequences and with economic impact, since when it does not cause death, causes sequelae that will affect the victim throughout his life. With regard to children, the prevalence of drowning death is higher than deaths caused by tuberculosis or measles. Considering the context of these accidents, it is known that the immersion occurs without shouting or "noises", which makes it even more difficult to detect and rescue. Rescue agility is crucial for the survival of victims, as after being submerged for only 2 minutes, the victim loses consciousness and after 4 minutes brain damage can become permanent and unalterable. Even if they survive from being submerged for some time, the victims may suffer from severe and often irreversible neurological sequelae [1, 2]. From this perspective, developing safety mechanisms for children requires knowledge of the unique needs of these individuals, arising from the cognitive and motor development of this stage of human development [3, 4]. To foster this problem, the work proposes to develop a usual garment that contains an integrated rescue device for children. The main design challenge is the harmonious matching of the rescue device's function with the fashion item, making it unnoticed. The work presented is feasibility study (online survey), which aims to verify the acceptance of parents/guardians regarding the launch of such product concept, which is presently under development, and the requisites that it should comply with.

Abstract: Ni-P-Zn nanocomposite coatings were plated on mild steel surface from sulphamate rich bath containing (α-Si₃N₄ and α-ZrBr₂) nanoparticle produced via electrodeposition process. The compositions of the particulate were varied from 0 to 10 wt% with time variation between 10 to 25 min after ascertaining other optimum parameters. The crystal evolution and morphological quantification were examined using scanning electron microscope supported with energy dispersive spectroscopy. The corrosion degradation in an acidic and alkaline environment was considered and compared to establish the suitability and extents of the corrosion vulnerability of deposited coatings. The surface flake crystal identified on the microstructural properties show the presence of compositional constituent and disperse particle of α-Si₃N₄ and α-ZrBr₂. Finally, corrosion properties show a resilient crystal surface stability in the presence of chloride and sulphate ion with a remarkable surface film still retained at the bulk interface. This study has confirmed that α-Si₃N₄ and α-ZrBr₂ composite coating can be used for structural development and corrosion improvement in the presence of active ions.

Abstract: The pull out and well drop accident caused by serious thread galling damage of low alloy steel tubing connections were investigated in this paper. Representative samples were selected from five failure accidents, and the test and verification program were designed. Based on the experiment and analysis it is considered that the material used for tubing and the quality of thread processing meet the requirements of the standard. The field end of tubing connection pull out may be due to the serious thread galling damage, which reduced the joint strength. Using the torque-position control method to make-up the thread connections in oil field may ensure the connection quality and the connection strength, meanwhile, and hence to avoid the occurrence of tubing pulling out effectively.

Abstract: The Karakoram Highway (KKH), from Islamabad of Pakistan to Kasha of China, passed through the junction areas of the mountains of Karakoram, Himalaya and Hindu Kush and suffers serious destruction of different geo-hazards. This work analyzed distribution and characteristics of geo-hazards, including debris avalanches, rock falls, debris flows, landslides and flash flood along Khunjerab River from Sost to Khungerab and their destructions on KKH(K726~K821). These geo-hazards are commonly initiated by intensive rainfall and melting of glacier and snow, and numerously occurred, especially debris avalanches, rock falls and debris flows, to seriously destruct highway and frequently interrupt traffic. The destructions of highway mainly came from the burying of landslides, debris flows and debris avalanches, the scouring of debris flow and flash flood, the submerging of dammed lakes induced by debris flows and landslides as well as the breaking of rock falls. After analyzing the lessons and experience of geo-hazards mitigating and highway protecting since 1970s, the measures of hazards mitigating, including identifying potential hazard sites,controlling and disposing rock falls in time,integrated controlling debris avalanches, debris flows, landslides and flash flood, establishing emergency treatment plans for hazard chain and founding hazards alarming and highway safe protecting system, are strongly suggested for highway protecting and traffic security.

Abstract: Retracted paper: SQL injection came with a bang and caused revolution in database attacking. Inrecent years, with the explosion in web-based commerce and information systems, databases havebeen drawing ever closer to the network and it is critical part of network security. This paper is incorporated with our research and firsthand experience in hacking the database by SQL injection. Database is the Storage Brain of a website. A hacked database is the source for Passwords and juicy information like credit card number, bank account number and every important thing that are forbidden. Importance should be given for preventing database exploitation by SQL injection. The aim of this paper is to create awareness among web developers or database administrators about the urgent need for database security. Our ultimate objective is to totally eradicate the whole concept of SQL injection and to avoid this technique becoming a plaything in hands of exploiters.
