background: icter is the most prevalent disease in newborns. although most of the newborns affiliated with this seem healthy in other aspects, there is always a fear for toxic complication of indirect hyperbilirobinemia in the central nervous system. if the level of indirect bilirobin increases in the plasma to a level, which denotes the probability of danger, phototherapy must be carried out i...
Topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine CSR2, CSR4 and CSR2XCSR4 crossbreed races of the silkworm, Bombyx mori L. The results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoo...
This case report presents an implant-aided prosthetic treatment in which peri-implant plastic surgery techniques were applied in combination to satisfactorily attain functional aesthetic expectations. Peri-implant plastic surgery enables the successful reconstruction and restoration of the balance between soft and hard tissues and allows the option of implant-aided fixed prosthetic rehabilitation.
Plastic materials are widely used in geotechnical engineering, especially as geosynthetics. The use of plastic-based products involves serious environmental risks caused by their degradation. Innovative research has been focusing on biodegradable polymers natural origin, poly(lactic acid) (PLA), to reduce the plastics. This study aims explore potentiality biopolymers for production geogrids, me...
High-speed melt spinning of a cyclo-olefin polymer (COP) and a copolyamide (CoPA) have been performed. Differential scanning calorimetry curves of the resulting monofilaments show that they remain in an amorphous state even after hot drawing. Wide angle x-ray diffraction patterns of undrawn and drawn COP filaments show that although the material remains in an amorphous state, a degree of orient...
By combining the aeroelastic and vortex-forced flutter modes of a thin plastic strip, its oscillation frequency can be confined to scale monotonically with fluid velocity. This principle has been used to produce a low-cost, mm-scale anemometer that measures air speed to ±(5% + 0.5m/s) from 118m/s. The device uses a 2mm slot-type photointerrupt detector to monitor the fundamental frequency of a ...
Biopolymers, such as poly(lactic) acid (PLA), which is obtained through green synthesis pathways from renewable resources, has attracted considerable interest in recent years because of the increasing need to reduce petroleum-based plastic pollution and bringing their prices comparable with conventional thermoplastic commodities’ price (e.g., polyethylene, polypropylene, polystyrene). The prese...
HYPOTHESIS An inexpensive temporal bone model for use in a temporal bone dissection laboratory setting can be made using a commercially available, consumer-grade 3D printer. BACKGROUND Several models for a simulated temporal bone have been described but use commercial-grade printers and materials to produce these models. The goal of this project was to produce a plastic simulated temporal bon...
an evolutionary structural optimization (eso) method is used for plastic design of frames. based on safe theorems some criteria are derived and made an effort to satisfy them during the optimization process. in this regard, equilibrium is checked and yield condition is gradually satisfied during the optimization process. in this method, the amount of used material and the stiffness for each ele...
