Cyber insurance is an influential means for educating Internet security. Cyber insurance has progressed from outmoded insurance rules to primary cyber risk insurance rules to contemporary compete cyber insurance products. E-insurance rules are attractive more complete as insurance corporations better comprehend the sight of dangers and detailed commercial requirements. More precisely, cyber-operators discourse what remained measured insuperable difficulties (e.g., asymmetric data, moral threat, negative collection, etc.).

Saudi Arabia is among the countries that have very high prevalence rates of diabetes and hypertension, with prevalence rates of almost 18% and 25%, respectively. The majority of patients with diabetes and hypertension fail to manage their diseases and to show up for their follow up appointments. Mhealth technology is among the interventions that have been recently adopted to overcome these issues and improve the quality of healthcare services.

Household hazardous waste is hazardous waste generated by households in relatively small quantities (between 1% and 4% of municipal solid waste) and containing toxic or labeled toxic, flammable, reactive, explosive or corrosive chemicals such as automobile products, cleaning products, personal care products, maintenance products, unused medications, insecticides, garden pesticides, products containing heavy metals, photographic chemicals. Many of these wastes are regulated at the industrial level in larger quantities.

Recently, with the development of digital technology and the spread of the social media network and made the communication of human beings between each other more easily, but with the put the personal information and private evidence and the participation of others via the Internet, it causes a great danger that this information can be exploited and collected, and from this a new concept called social engineering has spread that is the attackers or whoever wants Damage to people searches and collects personal and confidential information to penetrate and cause harm to the victim.

The Internet of Things (IoT) has the potential to transform healthcare dramatically via changing the way hospitals, clinics, and other healthcare facilities collect and use data. IoT can bring together major technical and business trends related to mobility, automation, and data analysis to improve patient care delivery. IoT is the networking of physical objects such as on-board sensors, actuators, and other equipment that collect and transmit activity information in real-time across the network.

Denial of service attack was a stretch of Distributed Denial of Service Attack (DDoS). DDoS comes the largest security risks and problems facing Internet users. This risk affecting obstruct with work of any system of targeted organizations, which leads to the harassment of system customer. This attack succeeds by exploiting several weaknesses to access resources in the target organizations. The attacker exhausts all capacity of resources in a period short time. The previous method leads to the denial of using any organization's resources from any authorized user.

This work concerns an experimental study of beef drying with a mixed tunnel solar dryer with forced convection. Drying experiments were carried out at the Centre for Study and Research on Renewable Energies (CERER). The evolution of air and product temperatures as a function of irradiance and the position of the racks was studied, as well as the effect of treatment and air temperature on drying speed. The experimental curves presented in terms of reduced moisture content as a function of drying time are approximated by mathematical models of existing drying kinetics.

In the last few years, power demand has increased substantially while the expansion of power generation and transmission has been severely limited due to limited resources and environmental restrictions. As a consequence, some transmission lines are heavily loaded and the system stability becomes a power transfer-limiting factor. Flexible AC transmission systems (FACTS) controllers have been mainly used for solving various power system steady state control problems. Flexible AC transmission systems or FACTS are devices which allow the flexible and dynamic control of power systems.

The blockage of the erect muscle fascia (ESP) of the spine is a relatively recent technique that was first described by Forero et al. In September 2016. It has applications in the control of chronic pain with neuropathic component of the thoracic wall, where its original usefulness is born in metastatic rib disease and a defective bonding pathology of multiple coastal fractures. Recent anatomical and radiological research into corpses indicates that the likely site of action for such blockage is in the dorsal and ventral branch of the thoracic spinal nerves.

Background: most persons will experience acute low back pain during their lifetime. The first epi¬sode usually occurs between 20 and 40 years of age. Objectives: to investigate the effect of intermittent sitting on the lumbar range of motion of prolonged standing low back pain developers. Methods: 60 subjects participated in this study. They were randomly distributed into two equal groups; group I involved 30 subjects were stood for 15 min. and sit for 5 min. Group II involved 30 subjects where stand for 30min and sit 10 min throughout the workday for 8 hours.
