Activated carbon (AC) is a versatile adsorbent that used in the treatment of waste water, colour, odour removal and CO2 capture. Annogeissus leiocarpus one abundant agricultural precursor can be for production activated carbon. Characterization was done to investigate some proximate parameters. The modifications were made by soaking AC 40% H2SO4 NaHCO3 24hours ration 1:3 w/v. FT-IR SEM conducte...

IntroductionThe treatment of degenerative meniscal lesions usually consists conservative measures such as physical therapy or knee injections. Recently, the use orthobiologics, in form platelet-rich plasma and cell-based therapies, gained huge popularity orthopedic practice.ObjectivesThe aim present systematic review is to summarize available evidence concerning orthobiologics lesions.Data sour...

The technique of microfracture (MFX) was first performed 40 years ago and served for many as the main procedure repairing cartilage defects. There is a need to improve microfractures because regenerated differs from original histological aspect; it less hyaline more fibrocartilaginous. In addition, importantly, benefits do not persist long-term results are unsatisfactory. Adjunctive treatments ...

This article gives a comprehensive review of two-step single surgical alternative that searches to preserve the patient's cartilage and joint. It addresses knee from 360-degree perspective; First, articular side, full-thickness lesions are treated with hyaluronic acid (HA) scaffold combined bone marrow aspirate concentrate (BMC), which restores hyaline-like tissue. Then, deep inside subchondral...

This paper proposes an energy-efficient detection scheme, referred to as AdaSense, that is particularly suitable in the sparse regime when events be detected happen rarely. To minimize energy consumption, AdaSense exploits dependency between receiver noise figure (i.e., added noise) and power consumption; less noisy channel observations typically imply higher consumption. duty-cycled begins eac...

This paper introduces a mobility-aware medium access control protocol for multi-hop wireless sensor networks (MA-MAC). The protocol evaluates the RSSI values of acknowledgement packets and determines whether a gradual deterioration in the RSSI values eventually leads to a disconnection. If it does, it initiates a handover by switching transmission from a unicast to a broadcast mode and by embed...

In this paper we present X-MAC, a low power MAC protocol for wireless sensor networks (WSNs). Standard MAC protocols developed for duty-cycled WSNs such as BMAC, which is the default MAC protocol for TinyOS, employ an extended preamble and preamble sampling. While this “low power listening” approach is simple, asynchronous, and energy-efficient, the long preamble introduces excess latency at ea...

Orthoregeneration is defined as a solution for orthopedic conditions that harnesses the benefits of biology to improve healing, reduce pain, function, and optimally, provide an environment tissue regeneration. Options include: drugs, surgical intervention, scaffolds, biologics product cells, physical electro-magnetic stimuli. The goal regenerative medicine enhance healing after musculoskeletal ...
