In most domestic and commercial refrigeration systems, frost forms on the air-side surface of the air-to-refrigerant heat exchanger. Frost-tolerant designs typically employ a large fin spacing in order to delay the need for a defrost cycle. Unfortunately, this approach does not allow for a very high air-side heat transfer coefficient, and the performance of these heat exchangers is often air-si...

The Pseudomonas genus is a big problem mainly for the poultry food industry. The shelf life of chicken carcasses stored under refrigeration is limited by the appearance of undesirable odors and sliminess surface generated primarily by Gram negative bacteria. Due to the subsequent emergence of resistant bacteria, is necessary proving new alternatives as guaranty the microbiological quality of fo...

Air-to-air heat/energy recovery ventilators can effectively reduce the cost associated with ventilating a home. However, high indoor moisture levels, in conjunction extreme temperature differences between outdoor and air cause frost accumulation mechanical equipment, leading to performance degradation or failure. In this research, demonstration house using heat ventilation system Iqaluit, Nunav...

The single core Energy Recovery Ventilator (ERV) used in this study is equipped with defrost control that recirculates the exhaust indoor air, while keeps outdoor air intake damper closed. This strategy has disadvantage of reducing supplied to house, which may affect quality. First, paper presents new correlation-based models supply temperature T 2 after energy recovery during normal and operat...

In the Canadian north, cost of space heating is very high due to harsh weather, its remoteness, lack transportation, and dependency on fossil fuel imported from South. Since North has an abundance solar energy, significant energy savings with some added construction in houses could be achieved by applying high-performance building envelopes design strategies. The objective this paper investigat...

9 Low enthalpy geothermal energy is a renewable resource that is still underexploited nowadays, in 10 relation to its potential for development in the society worldwide. Most of its applicabilities have 11 already been investigated, such as: heating and cooling of private and public buildings, roads defrost, 12 cooling of industrial processes, food drying systems, desalination. 13 One of the ma...

One consequence of current technological advances is that we can imbue everyday objects such as our fridges, ovens, fires, doors, thermostats, tvs and stereos with processing power. Not only will this enable them to make decisions based on their current state and model of the world about their current behaviour (the oven may automatically turn itself off when there is an excess of smoke) it wil...

Due to controversial evidence in the literature pertaining to the activity of plasminogen activator inhibitor-1 in platelets, we examined the effects of residual platelets present in plasma (a potential pre-analytical variable) on various plasminogen activator inhibitor-1 and plasminogen activator inhibitor-1-related assays. Blood samples were collected from 151 individuals and centrifuged at 3...

HER2DX is a genomic test for early HER2+ breast cancer clinically available since January 2022 as Laboratory Developed Test. Based on the expression of 27 genes (nCounter) plus tumor and nodal staging, it predicts risk relapse (risk-score), probability achieving pathological complete response (pCR-score), individual levels ERBB2 (ERBB2-score). Here, we report analytical validation performed in ...

Textured soy protein is a food alternative that can partially replace animal derivatives, and meet some dietary restrictions, its use in ready-to-eat dishes will make practical preparation. The objective was to carry out the evaluation of stroganoff formulations at IF Goiano Campus Ceres. Three (traditional, light lactose-free) were prepared, stored two types packaging (for conventional oven mi...
