Engineering considerations in the design of tissue specific bioink for 3D bioprinting applications.

Over eight million surgical procedures are conducted annually in the United Stats to address organ failure or tissue losses. In response to this pressing need, recent medical advancements have significantly improved patient outcomes, primarily through innovative reconstructive surgeries utilizing tissue grafting techniques. Despite tremendous efforts, repairing damaged tissues remains a major clinical challenge for bioengineers and clinicians.

Application of exosomes in tumor immunity: recent progresses.

Exosomes are small extracellular vesicles secreted by cells, ranging in size from 30 to 150 nm. They contain proteins, nucleic acids, lipids, and other bioactive molecules, which play a crucial role in intercellular communication and material transfer. In tumor immunity, exosomes present various functions while the following two are of great importance: regulating the immune response and serving as delivery carriers.

Farmers Interpretation of Pesticides Pictograms and Their Adherence to Different Ergonomic Principles for Different Sizes.

Objective: The objective of this study was to investigate the effect of the size of pesticide pictograms on comprehensibility and their adherence to principles of familiarity, compatibility, and standardization. Pictograms usually involve complex details, and space limitation demands size reductions, which reduces overall comprehensibility, especially in agriculture and healthcare.

Methods: Two experiments were conducted.

An effective ECG signal compression algorithm with self controlled reconstruction quality.

Electrocardiogram (ECG) signals are frequently used in the continuous monitoring of heart patients. These recordings generate huge data, which is difficult to store or transmit in telehealth applications. In the above context, this work proposes an efficient novel compression algorithm by integrating the tunable-Q wavelet transform (TQWT) with coronavirus herd immunity optimizer (CHIO).

Comparative ergonomic assessment of manual harvesting of un-lodged and lodged paddy crops post-tropical cyclone in India.

Objective: In recent times, increased rainfall from tropical cyclones due to climate change affects the agricultural sector, mainly the paddy fields. High windspeed with excessive rain causes lodging of paddy crops, which is difficult to harvest. Mechanized harvesting systems are ineffective in this situation due to waterlogging in the fields.

A hybrid salp swarm algorithm based on TLBO for reliability redundancy allocation problems.

A novel optimization algorithm called hybrid salp swarm algorithm with teaching-learning based optimization (HSSATLBO) is proposed in this paper to solve reliability redundancy allocation problems (RRAP) with nonlinear resource constraints. Salp swarm algorithm (SSA) is one of the newest meta-heuristic algorithms which mimic the swarming behaviour of salps. It is an efficient swarm optimization technique that has been used to solve various kinds of complex optimization problems.

Structural, magnetic, and dielectric properties of solution combustion synthesized LaFeO, LaFeMnO, and LaMnO perovskites.

Nanocrystalline LaFeO, LaFeMnO, and LaMnO perovskites have been synthesized by a novel solution combustion route, in which oxalyl dihydrazide (ODH) has been used as a fuel. These materials have been characterized using several physicochemical techniques. LaFeO and LaFeMnO adopt an orthorhombic structure and LaMnO crystallizes in a rhombohedral structure as demonstrated by X-ray diffraction (XRD) patterns.

Tire Tread Removing Units in Central India: Risk Factors and Potential Interventions.

Occupational ApplicationsRisk factors for work-related musculoskeletal disorders were found to be prevalent in the informal work sector of tire tread removing units at Jabalpur in Central India. A majority of the tasks examined were in high-risk category requiring immediate ergonomic intervention. We show that using relatively simple methods, with little training, can aid in early detection of risk factors and thus help to prevent the onset of work-related musculoskeletal disorders.

Ergonomic analysis and design intervention in symbols used in hospitals in central India.

People visiting different Government Hospitals at Jabalpur in central India, were facing problems in comprehending different symbols. One of such hospital authority approached the research team for developing new symbols which could be easily comprehended by the users. Based on this, the current study was conducted, which included two experiments.

Solution combustion synthesis, characterization, magnetic, and dielectric properties of CoFeO and CoMFeO (M = Mn, Ni, and Zn).

Nanocrystalline CoFe2O4 and Co0.5M0.5Fe2O4 (M = Mn, Ni, and Zn) ferrites were prepared by the solution combustion method using oxalyl dihydrazide as a fuel.

Ergonomic analysis of a traditional vehicle plying in rural and semi-urban areas in western India.

Chakdos in Western Indian state of Gujarat are makeshift vehicles for public transport. Such a vehicle was selected for ergonomic analysis. The objective of this study was to evaluate the design of the existing vehicle from an ergonomic viewpoint and to redesign it from an ergonomic perspective.
