Human Resource Management, the focus of my project, is the division inside an organization that oversees hiring, managing, and monitoring the organization’s employees. The importance and relationship between environmental scanning, cultural audits, strategic planning, and diversity management techniques are among the key elements of strategic human resource planning (HRP). The goal is to discuss HRM management strategies with managers. The difficulties of the workplace that HRM deals with include compensation, hiring, performance management, organization development, safety, wellness, benefits, employee engagement, communication, administration, and training. Concentrates on employment enrichment, a method for employee motivation that helps motivated workers.
The Halawa House is one of the unique houses that represent a destination for the Arab Islamic character. It belongs to the family of Ismat Ahmed Halawa, a wealthy family in Alexandria. It was designed by the architect Abdel Wahed Al-Wakeel in 1975 on a surface of 455 square meters. The design was awarded the Aga Khan Award for Architecture in 1980. The architect designed This house is to be compatible with the traditional Arab and Egyptian buildings and benefited from the style used in Arab environments by constructing internal courtyards to cool the air and modify the internal climate of the house. Halawa House is considered one of the highlights in the Arab and Islamic architecture, and it consists of living room, loggia, guest bedroom, kitchen, maid’s room, garage, master bedroom, and bedroom. In this project, I will draw a plan for the ground floor and a vertical section using ¼ scale for Halawa House.
Classical Mechanics and Quantum Mechanics both have the word “Mechanics”, but they are different. In classical mechanics, we have the “trajectory” of the object while forces are acting on it. If we know and list all the forces, potential energy and so on, we can compute the motion/position of the object at any moment of time. However, in quantum mechanics there is no exact “trajectory” of the particle, we have only the probability of the position, momentum, and energy of the object, that is calculated from the wave function. We can only tell where the particle is found after the measurement.
RFID- Radio Frequency Identification is the wireless transfer of data to or from electronic tags that are attached to items. It consists of low frequency(LF) 125KHz-134KHz, high frequency (HF) 13.56 MHz, and Ultra-High frequency (UHF) 300MHz-3GHz. Along with RFID, a novel reader-free RFID system has been proposed in recent years where tags can communicate with each other directly with the existence of some external RF carrier source or an ambient RF signal. This system is capable of directing tag-to-tag communication in the presence of an external radio frequency field. Two or more radio-less devices (tags) communicate with each other purely by reflecting (backscattering) an external signal (whether ambient or intentionally generated). Finally, the relative phase difference between the backscatter signal and the external excitation signal at the receiving tag has a large impact on the envelope of the resulting signal.
This research is aimed at comprehensively evaluating dental implant immunological factors in a comprehensive way. In this study, the immunological reactions have been investigated from three aspects: cellar, humoral, and allergy. This classification of the subjects in this study rises from the fundamental differences in the mechanisms of each part. Cellular and humoral immunity are principals of the immune system, and allergy is a subject in which these two principles overlap, so they are classified separately. One focus of this review is to outline the up-to-date knowledge of immune responses to biomaterials. Understanding the complex interactions of host response and material implants reveals the need for and also the potential of “immunomodulating” biomaterials. Based on this knowledge, we discuss strategies for triggering appropriate immune responses by functional biomaterials and highlight recent biomaterials approaches that mimic the physiological extracellular matrix and modify cellular immune responses.
Alzheimer’s disease is the most common form of dementia that affects more than 40 million people around the world. The incidence is expected to rapidly increase due to the lack of any effective treatment. Although there is no cure for Alzheimer’s at the moment, there are significant attempts to identify novel strategies to stop the disease’s progression. A wealth of evidence suggests that blocking the action of phosphodiesterase type 5 (PDE5) can delay or halt the progression of the disease. In this research, we utilized computational molecular methods to find small drug inhibitors of the protein PDE5. We have modeled four different drugs and performed flexible molecular docking simulations so we looked for the best binding location between the drug and the protein. Our results not only found one of the modeled drugs to be more potent than the other three but also allowed us to now understand how this drug attaches to the binding site. This is in correlation with in vitro and mouse model results obtained on the same drug. Our next step will be to chemically modify the compound so we can further improve the binding affinity to PDE5.
My research topic is Natural Language Processing for disaster tweets, my goal is to develop a model that looks through a series of tweets in order to determine which is about natural disasters. This is important as this information can be used by several outlets, news organizations, response teams etc. Datasets containing several tweets are used and a decision tree model is used in order to determine which tweets are about natural disasters. The model is then used on a testing dataset also containing several tweets in order to determine its accuracy. Based on the results, the model is quite accurate, although its efficiency can be improved in order for it be used on a larger scale for commercial purposes.
Teeth are complex biocomposites with well-structured and hierarchically organized material characteristics. They occur in or around the jaws and pharynx of vertebrates. Teeth are composed of four main dental tissues: enamel, dentin, cementum, and pulp. Modern dental care is an important aspect of health care in general. In line with this, toothpaste plays a critical role in maintaining appropriate dental hygiene. The aim of this review project is to describe and understand the chemical structure and composition of teeth as well as basic elements of dental care, such as toothpaste or mouthwash. In addition, the most recent research and findings in the development of modern toothpaste were explored and discussed. After conducting this research, we found that chemistry plays a huge role in dentistry to maintain an understanding of our oral health; such as when using fluoride. Fluoride can replace some of the hydroxyl ions, which gives much greater resistance to acid and aids remineralization, however, if the fluoride concentration is too high during the formation of the tooth, the enamel can soften and take on a mottled appearance.
Besides understanding how species are related to humans, have you ever thought about it from a molecular standpoint? Calpains are a family of ubiquitously expressed calcium-dependent, non-lysosomal cysteine proteases involved in apoptosis, cellular proliferation, and cell motility. Calpains are found in some eubacteria and almost all eukaryotes but not in archaebacteria. Tetrahymena thermophila is a ciliate found in freshwater. Remarkably, these cells have two nuclei, one is the germline nucleus, and the other is the somatic nucleus. T. thermophila has been used as a model to study many cellular processes. However, the role of calpains in these cells is yet to be examined. The purpose of this project is to begin examining the role of TTHERM_00486970 in oxidative stress regulation. Cells were exposed to different amounts of cadmium (data not shown) and hydrogen peroxide, oxidative stress inducers, for 2 and 24 hours. RNA was extracted followed by cDNA synthesis. PCR was performed using primers for TTHERM_00486970. Preliminary results show TTHERM_00486970 mRNA decreased after 4 hours when exposed to 50 – 100 µM of hydrogen peroxide, but increased when exposed to the same stress for 24 hours. These results suggest TTHERM_00486970 may have a role to play in cadmium-induced oxidative stress. More studies are needed to better understand the role TTHERM_00486970 may have in oxidative stress regulation.
This project focuses on the use of mobile robots for educational purposes. Specifically for robotics competitions. It follows the guidelines for the IEEE Micromouse robotics competition. Where the robot takes in feedback from its environment to complete a maze. For this project, the robot used infrared sensors to solve a line maze and a sonar sensor to complete a walled labyrinth. Competitions are important for students’ development because the competition’s challenges serve as an excellent learning tool. It forces the students to practice their problem-solving skills, as well as use their robotics and programming knowledge to accomplish the tasks. The maze competition gives the students experience with sensors highly used in the industry.
