Energy audits in university buildings in a tropical climate: assessments of air conditioning consumption

We evaluated aspects of energy consumption by air conditioning units in the Polytechnic School (PS) and the Faculty of Architecture (FA) of the Federal University of Bahia (UFBA), Brazil. The methodology involved a Level I energy audit based on energy consumption data in those two departments, information concerning the efficiencies of air conditioning units in operation between 2013 and 2018, and interviews with management agents and users. We encountered mid-level indicators of energy use, corresponding to 58 kWh/m²/year in the PS and 40 kWh/m²/year in the FA.

Parkinson’s disease detection using machine learning

Parkinson's disease is a condition in which dopamine-producing cells in the brain die. Parkinson's disease symptoms appear as the amount of dopamine in the brain diminishes. Parkinson's disease is a slow-progressing condition with symptoms such as tremors in the hands, arms, legs, chin, and face that get worse with time. People may have trouble walking and speaking as the condition advances. Although there is no cure for Parkinson's disease, the symptoms of the disease can be alleviated with the use of some medications.

Endoguide system: a new concept for the removal of fiberglass pins

O objetivo desse caso clínico foi demonstrar o procedimento de remoção do retentor intrarradicular de fibra de vidro (PFV) do elemento 25, que havia fraturado na região cervical do dente, com auxílio de guia Endoguide. Foi realizada tomografia computadorizada para a visualização da localização exata do PFV e verificar a existência de mais de um canal. Como o PFV é difícil ser visualizado dentro do canal, foi proposto o conceito Endoguide para auxiliar nessa remoção. Foi realizado o escaneamento do elemento dental, confeccionado a guia Endoguide, a qual foi instalada no paciente.
