Sonography is common use in early pregnancy has led to the exposure of incidental adnexal masses more often. Assessment of grayscale and color Doppler sonography outcomes is as precise when based on static images. To determine the evaluation of adnexal masses with grayscale ultrasonography and color Doppler flow imaging in first trimester of pregnancy. This Cross Sectional study was conducted at the Department of Radiology, Jinnah Hospital, Lahore, Pakistan. The study was conducted from July to Dec 2019. The patients were selected by nonprobability convenience sampling. All pregnant patients were undergoing abdominal ultrasonography to detect the adnexal masses. The data was collected by the questionnaire. Overall 68 individuals involved in this study out of which 29(96.7%) are benign diseases on the left side of patients and malignant are only 1(3.3%). Patients having benign diseases of right-sided are 33(86.8%) and malignant are 5(13.2%). Benign diseases are 62(91.2%) out of which 43 patients had cystic, 15 are mixed and 4 are solid components. Malignant diseases are found only 6 patients out of which 3 are mixed and 3 are solid components. Majority of the adnexal masses identified in pregnancy is benign and will resolve suddenly. Doppler sonography has severe limitations in the differentiation of benign from malignant adnexal disease on the basis of low-impedance flow.

This paper presents the band gap design and J-V characteristic curve of Zinc Oxide (ZnO) based on Junction Field Effect Transistor (JFET). The physical properties for analysis of semiconductor field effect transistor play a vital role in semiconductor measurements to obtain the high-performance devices. The main objective of this research is to design and analyse the band diagram design of semiconductor materials which are used for high performance junction field effect transistor. In this paper, the fundamental theory of semiconductors, the electrical properties analysis and bandgap design of materials for junction field effect transistor are described. Firstly, the energy bandgaps are performed based on the existing mathematical equations and the required parameters depending on the specified semiconductor material. Secondly, the J-V characteristic curves of semiconductor material are discussed in this paper. In order to achieve the current-voltage characteristic for specific junction field effect transistor, numerical values of each parameter which are included in analysis are defined and then these resultant values are predicted for the performance of junction field effect transistors. The computerized analyses have also mentioned in this paper.

This paper presents the metal-semiconductor band structure analysis for metal-oxide semiconductor field effect transistor (MOSFET). The energy bands were observed at metal-semiconductor and semiconductor-metal junctions. The simulation results show energy variations by using gallium-nitride (GaN) material. Gallium nitride based MOSFETs have some special material properties and wide band-gap. From the energy band, the condition of contact potential, conduction and valence band-edges can be analyzed. The computerized simulation results for getting the band layers are investigated with MATLAB programming language.

The circulation system is a vital linking infrastructure that connects various activities and uses land on an area and inside a building that considers functional, economic, flexibility and comfort aspects. The explanation of this theory emphasizes the uniqueness of the building itself. So that there are various shapes of buildings in an effort to adjust to environmental conditions, climate, and natural surroundings. As a result, the resulting building has a special shapeation in accordance with the idea of an architect.

This paper reviews and analyses the process and built-up of the ArtScience Museum. It touches on the history, building features and Moshe Safdie’s design approach in forming the museum’s architecture. Furthermore, it explores the motivations in having a cultural institution within the Marina Bay precinct and the correlation of what it was intended to be with the identity it has formed today. The Art Science Museum can be seen as a form of an add-on to Marina Bay Sands as the tender competition project included a design for a cultural institution. However, despite it being a form of enhancement, the ArtScience Museum arose and served its purpose being an intriguing form of architecture and a place for learning for people alike.

The planning of the Art Plaza in Makassar can fulfill the need to encourage the spirit of work and creativity for artists and build a forum and as a bridge of appreciation of art and culture with the community. Location determination analysis is based on taking into account the basic considerations taken and the division of Makassar City and several factors that need to be considered in determining the location of Plaza Seni, including; accessibility for transportation and communication lines, location must be easily accessible to the community or close to the highway and available infrastructure and facilities easily, for example; available pedestrian, accessible for people with disabilities. An adequate location for planning an art plaza is in the district of Ppanakukkang, Kelurahan Paropo. From the location of the site, it can be concluded that the chosen site is feasible enough to become a planning site for the construction of Plaza Seni in Makassar.

Analyzing the Influence of Rain Frequency Infiltration Rate and Infiltration Capacity in Common Soil Type (Laboratory Testing Study With Rainfall Simulator). Infiltration is the flow of water into the ground through the soil surface. This process is a very important part of the hydrological cycle and in the process of transferring rain into the flow of water in the soil before reaching the river. Infiltration (infiltration rate and capacity) is influenced by various variables, including soil type, slope inclination, density and type of vegetation, soil moisture content, and rainfall intensity. This study aims to determine the effect of rainfall frequency on the infiltration rate and infiltration capacity on common soil types. This research is a type of laboratory experimental research, using rainfall simulator tool. The soil used in this study is common soil type. Furthermore, artificial rain was provided with intensity I5, I15, and I25 and performed infiltration rate reading on the Drain Rainfall Simulator. The rate and capacity of infiltration in common soils increase proportionally to the increased intensity of rainfall, the higher the intensity of rainfall the higher the infiltration occurring at the same level of rain frequency. The rate and capacity of infiltration in common soils decrease proportionally to the increasing frequency of rain, the more the frequency of rain the smaller the infiltration occurring at the same level of rainfall intensity

Analysis of Effect of Land Gradation on Permeability and Ponding Time in Frequency of Repeated Rain (Laboratory Studies with Rainfall Simulator) guided by Darwis Panguriseng and Mahmuddin. That soil permeability is the ability of soil to pass water or air. Soil permeability is usually measured in terms of the speed of water flowing in a certain time specified in units of cm/hour. Ponding time (tp) is the time difference between when it rains and the time when water begins to pool above ground level. The purpose of this study was to determine the effect of soil grading on permeability and inundation time with repeated frequency of rainfall with the same intensity on mixed soil types. This research method is a type of laboratory experimental research, using a rainfall simulator. The soil used in this study is mixed soil types. Furthermore, artificial rain is given with an intensity of I15, each intensity is used five times the frequency of rain and the inundation time readings and inundation height are carried out in the Rainfall Simulator experiment tank and for the permeability test, observation is done with the constant head test. The results showed the value of the permeability coefficient is inversely proportional to the increase in rainfall intensity and frequency of rain. Inundation height and final inundation time are directly proportional to increasing rainfall intensity and rainfall frequency.
