Trauma is the principal reason of deaths in kids and young adults globally. Objective: To determine the causes and management of blunt liver trauma in a tertiary care hospital in Peshawar. Methods: The present investigation observed a total of 150 individuals through non-probability consecutive sampling to determine the mean hospital stay in patients presented with blunt liver trauma. Results: In this study, age distribution among 150 patients was analyzed as n= 10-20 Years 51 34.0%), 21-30 Years 35 (23.3%), 31-40 Years 16 (10.7%), 41-50 Years 23 (15.3%), 51-60 Years 25 (16.7%). Mean age was 41.56±5.357 years. Gender wise Distribution among 150 Patients was analyzed as Male were 94 (62.7%) and female were 56 (37.3%) Distribution of BMI among 150 patients were analyzed as n=Below 18.5 Underweight 76 (50.7%), 18.5–24.9 Normal weight 35 (23.3%), 25.0–29.9 pre-obesity 21 (14.0%), 30.0–34.9 Obesity class 18 (12.0%). Distribution Mechanism of Injury among 150 patients were analyzed as n= RTA was 57 (38.0%), fall from height was 52 (34.7%), Sport's injury was 18 (12.0%), physical assault was 23 (15.3%). Successful Conservative Management among 150 patients were analyzed as n= Yes was 106 (70.7%) and No was 44 (29.3%), Distribution of Mortality among 150 patients were analyzed as n= Yes was found 66 (44.0%) and No was found 84 (56.0%). Conclusions: The severity of liver damage and concomitant intra-abdominal injuries demonstrated a strong association with the chance of success with conservative therapy. The restricted hospital facilities and lack of agreement on traditional therapy had a detrimental influence on success.

Additive manufacturing (AM) techniques have promising applications in daily life due to their superiority over conventional manufacturing techniques in terms of complexity and ease of use. However, current applications of polymer-based 3D printing (3DP) are limited to small scale only due to the high cost of materials, print times, and physical sizes of the available machines. In addition, the applications of 3DP are yet to be explored for insulation of different large-scale mechanical structures. For example, milk vats are large structures with complex assemblies (like pipes, joints, couplings, valves, ladders, vessel doors) that requires insulation to store the milk at a low temperature of 6 °C as per the NZCP1 regulations in New Zealand. Generally, milk vats lack any kind of proper insulation around them and require additional cooling systems to keep the milk at a prescribed temperature. Any variations in the temperature can lead to deterioration in the quality of milk. Therefore, there exists a research gap that can not only help to solve an industrial issue but also can be a first step towards real large-scale 3DP applications that can potentially lead to many others in future. For example, pipe insulation, food storage tanks, chemical storage tanks, water treatment. This research explores new and inexpensive materials for large-scale 3DP. For this purpose, the current state of the 3DP materials is analyzed and based upon this analysis two distinct approaches are devised: 1) in-process approach to improve the mechanical properties of the existing materials like polylactic acid (PLA), and 2) modification of inexpensive materials (like materials used in injection, rotational, and blow moulding) to make them printable. In the first approach, by controlling the process parameters, mechanical properties are studied. While in the second approach, blends of high density polyethylene (HDPE) and polypropylene (PP) with different thermoplastics (acrylonitrile butadiene s
