The Automated Storage and Retrieval Systems are known as ASRSs which is moved by a mechanical system and controlled by electronical system. The system has introduced many advantages in the production, storage, distribution, and customer services. Many of the proposed systems use high techniques, complex programs, and an intractable interface, and besides their complexity in programming and using, they still at a high cost. The paper proposes a simple and low-cost Automated Storage and Retrieval System using Arduino boards to control the whole system. This work has been studied on specific sites, which are Chemicals Warehouses and Central Refrigerators. The system has been designed and implemented based on two components, Hardware and Software. The proposed system determines the types of goods, pick them up and put them on the suitable shelve depends on its type. The system was designed with a database to store information and an executable file installed in computers to follow up on entered quantities and to order quantities when needed.

Building materials comprise a diverse range of natural rocks that contain varying mineral components including radionuclides. Gamma spectrometry-based high-purity Germanium detectors were utilized to measure the activity concentrations of natural radionuclides: Radium-226 (226Ra), Thorium-232 (232Th), and Potassium-40 (40K) in various building rock samples found within and surrounding Taiz city. The activity concentrations of 226Ra, 232Th, and 40K vary from 27.79 ± 0.77 to 234.49 ± 3.13 Bq.kg-1, 25.82 ± 0.40 to 415.31 ± 2.47 Bq.kg-1, and 457.91±2.61 to 1139.56 ± 5.43 Bq.kg-1 with overall average value of 71.55 Bq.kg-1, 93.87 Bq.kg-1, 966.88 Bq.kg-1 respectively, these values were higher than the permissible thresholds. Furthermore, several radiation hazard indices were estimated including the radium equivalent (Raeq), the external hazard index (Hex), the internal hazard index (Hin), the gamma level index (Iɤ), the dose rate(Dɤ), the annual effective dose equivalent (AEDE), the excess lifetime cancer risk (ELCR), and the annual gonadal dose equivalent (AGDE). The findings illustrated that Basalt rocks have the minimum values of radiation hazard indices while the Himatite rocks have the maximum values of radiation hazard. The average values of radiation risks for most of building rocks fall below the recommended limits for safety. Based on the Radiation hazard indices of building rock samples, it can be concluded that with the exception of hematite rocks, all the examined rocks are considered safe for use in construction materials and pose non-significant radiation risks. The awareness about natural radioactivity levels of building rocks is critical for planning and performing strategies in radiation safety of buildings.

The public space with its components (streets and public parks) occupied an important place in the history of urban design and community health, as they are the determinants and resilient elements of health within cities. Modern concepts and design methods have been developed in response to urban health pandemics, including the creation of a healthy placemaking that achieves the health of the population within the urban context; Due to the lack of applications by principles healthy placemaking in streets and public parks in Sanaa, it has negatively impacted the daily health activities of residents, The research problem is that Sanaa's streets and public parks do not have any urban design to promote the health of Yemenis in the face of the pandemics; he study object is to create guided design models for the streets and public park in the study area, which simulate the applications of healthy placemaking to help planners provide solutions to face the spread of diseases and pandemics in urban areas, The importance of this research comes in the form of the first Yemeni urban study that deals exclusively with the issue of healthy placemaking in the streets and public parks during of urban health pandemics. The research followed the descriptive inductive approach in studying the theoretical concepts and the practical approach in creating design models the applications of the health placemaking during health pandemics on the study area.
