Approximately 450 million tons of plastic and agricultural waste are produced each year in the world. Only a small portion this is recycled, used as fuel or fertilizer, rest left environment burned, resulting environmental air pollution. For proper disposal, can be manufacture composites raw materials. In study, we had evaluated use bean pod powder (BPp) was natural reinforcing filler recycled ...

Purpose Many additively manufactured parts suffer from reduced interlayer strength. This anisotropy is necessarily tied to the orientation during manufacture. When individual features on a part have conflicting optimal orientations, unavoidably compromised. paper aims demonstrate strategy in which can be functionally separated into “co-parts” are individually aligned an orientation, selectively...

In material extrusion (MatEx) additive manufacturing, solid polymer filaments are fed into extruders to generate extrudates that needed build 3D plastic parts. There is a finite gap between the inner surface of an extruder and edge filament, which facilitates insertion translation filament inside extruder. It still not clear how this filled during extrusion. On other hand, it important know inf...

The Indonesian archipelago, especially Bali, has extensive coastline and marine waters. However, it is undeniable that some of these waters contain much plastic waste. Nusa Dua are located in the Bali Province area with many complex activities, ranging from port water sports, tourism, restaurants, hotels, fishing others, so they have a high potential for waste pollution. Plastic floats ocean wi...

The annual American Society of Plastic Surgeons’ “Plastic Surgery: The Meeting” is always filled with great educational events and endeavors, and the 2015 gathering in Boston was truly exceptional. Perhaps the most memorable and most rewarding panel that we had the honor and pleasure to be a part of was the Medical Student Session, moderated by one of the first Plastic and Reconstructive Surger...

Background A literature review did not reveal any study investigating the prevalence of depression among plastic surgery residents. Methods We conducted a cross-sectional mail survey and included all Saudi Plastic Surgery residents in our local program in Saudi Arabia. The Beck Depression Inventory II was used. Results The inventory showed that mild, moderate, and severe depressive symptoms...

Aesthetic plastic surgery is a branch of medicine using surgical techniques to alter the appearance of patients. In this paper it is considered whether aesthetic plastic surgery should be viewed as an art form. The question is answered by trying to see how aesthetic plastic surgery fits a number of classical concepts in philosophical aesthetics, concepts such as “artist” and “work of art”. Furt...

Randomized controlled trials are the gold standard of evidence-based medicine. In the field of plastic surgery, designing these studies is much more challenging than in pharmaceutical medicine. Randomized trials in plastic surgery encompass several road blocks including problems shared with other surgical trials: equipoise, high cost, placebo issues and learning curves following the establishme...

Introduction: Ensuring maximum patient safety as well as a complete surgical experience is of utmost importance in training for plastic surgery. As plastic surgical training relies on resident participation in various procedures, we must guarantee adequate hands-on operative time while maintaining the best possible outcomes for the patient. The effect of resident involvement on the outcomes of ...

Fig. 1. Our technique enables color printing with precisely controlled gradients using a filament printer. Le : The printer is equipped with an o -the-shelf nozzle that inputs multiple filaments (three in the picture) and outputs molten mixed plastic through a single exit hole. Such devices cannot directly be used to print gradients: the transition between mixtures takes time, and this timing v...
