The Application of Python Programming Language in the Automation of a Mathematical Model for Well Trajectory Selection Optimisation for a Given Field
Abstract: Directional drilling plays a major role in the exploration and recovery of hydrocarbons. There are three basic trajectories that a well may follow. They include; Build-and-Hold, Build-Hold-andDrop and Continuous-Build Trajectories. The selection of a trajectory is usually based on experience/trial and error approach and may be associated with errors. This work has therefore developed a mathematical model that optimised the automatic selection of a well trajectory type for a given …

SEMI-AUTOMATIC COW LIFTING MECHANISM
Abstract: There is a great difficulty faced by the farmers due to lack of machinery needed to move cows manually and are struggling much because of the high costs involved in handling the problem. The primary challenge dairy farms face is lifting the cow that has fallen over owing to excess weight gained during pregnancy, a leg injury, or an infection. These cows must be lifted by at least two people, …

Passive Capillary Flow of Aqueous Microparticle Suspensions in the Sudden Expansion PMMA Microchannels
Abstract: AbstractAuthor has fabricated a set of sudden expansions micro channels in the polymethylmethacrylate (PMMA) microfluidic devices by the maskless lithography, hot embossing lithography, drilling, air dielectric barrier discharge (DBD) plasma processing, direct bonding technique and chip separation technique. The surface-driven capillary flow of dyed water and three individual aqueous microparticle suspensions are studied with respect to the effects of channel aspect ratio, effective viscosity and surface wettability. The number densities …

Surface-Driven Capillary Flow of Aqueous Microparticle Suspensions as Working Liquids in the PMMA Microfluidic Devices
Abstract: AbstractPolymethylmethacrylate (PMMA) microfluidic devices have been fabricated by the maskless lithography, hot embossing lithography, drilling and direct bonding technique. The influence of effective viscosity on the speed of surface-driven capillary flow of aqueous microparticle suspensions has been studied. The surface-driven capillary flow of any particular aqueous microparticle suspension is faster in the microchannel of larger channel aspect ratio. Also, the surface-driven suspension flow is faster on the surface of higher …

Restoration of Carious Primary Molar Using Two Different Methods
Abstract: Management of dental caries in children using minimally invasive procedures has great importance. For this, various methods have been proposed such as chemo-mechanical methods for caries removal; Carisolv is one of them. The chemo-mechanical method of cavity preparation is considered to be less painful when compared to the traditional treatment method especially in children. In the present article is illustrated the case of a young girl in whom chemo-mechanical caries …

Is Platelet Rich Plasma (PRP) a Boon for Implant? – A Case Report
Abstract: Implant placement has been a constant challenge in the field of dentistry. The success of implants has been attributed to their firm bone anchorage, referred to as osseo-integration or functional ankylosis. Osseointegration has been defined as a direct structural connection at the light microscopic level between bone and the surface of load carrying implant. Platelet-rich plasma (PRP) is autologous platelet gel, plasma-rich growth factors (PRGFs), or mere autologous platelet concentrate. …

Achieving Surgical Accuracy in Implant Dentistry Using a CAD/CAM Stent: A Case Report
Abstract: Surgical accuracy is of utmost importance in implant dentistry as one of the most common aetiology of implant failure is related to incorrect placement. The surgical aspect of implant placement is vital to the stability, support and retention of the prosthesis to be placed later. CAD/CAM in dentistry has established strong footing in the field of Oral Implantology. The fabrication of a stent to guide the implant drill using CAD/CAM …

Application of Guided Surgery Concepts in the Programming and Intraoperative Management of Apicoectomies using a Surgical Template: A Case Report
Abstract: Apicoectomies are Endodontic Microsurgical procedures that require high precision. However, the state-of-the-art method currently used provides for a certain degree of imprecision as it heavily relies on the clinician’s judgment and experience with the sole aid of preliminary radiographic investigations. This clinical study aims to apply the Surgical Guided Approach, frequently used in Implantology, to Apicoectomies, thereby ensuring higher precision and, therefore, a lower amount of bone tissue loss as …

Piezo in Implant Surgery: A Literature Review
Abstract: Dental Implants are Titanium cylinders that are widely used by dentists as prosthesis to replace damaged or lost tooth. The process where the implant locks and attaches itself with the bone is termed as osseointegration. Factors like bone quality and quantity, primary stability of implant, surface characteristics of implant are some of the factors that determine osseointegration of the implant.Acceleration of osseointegration may depend on the removal of negative tissue …

Structural and Hydrogeological Characterization of the Olkaria Dome Geothermal Field, Lake Naivasha Basin
Abstract: The Olkaria Dome Geothermal Field in the Lake Naivasha Basin is one of Kenya's principal geothermal resource areas, where fluid circulation and reservoir performance are strongly controlled by geological structures and hydrogeological conditions. This study integrates geological, structural, hydrogeological, mineralogical, and soil-gas data to characterize reservoir permeability and fluid flow pathways. Correlation of lithological units with drilling circulation-loss zones identifies highly fractured formations that enhance geothermal fluid movement. Mineralogical mapping …
