The prediction and understanding of environmental conditions is of great importance to prevent and analyze changes in environment, supporting meteorological based sectors, such as agriculture. In that sense, this paper presents an Internet of Things (IoT) system for predicting climate conditions, i.e. temperature, using artificial intelligence by means of a supervised learning method, the artificial hydrocarbon networks model. It allows predicting the temperature of remote locations using information from a web service comparing it with a field temperature sensor. Experimental results of the...

The main purpose of this paper is to demonstrate the savings and economics of using an automated watering system within households. The paper will argue about a device capable of optimizing water consumption allowing water reuse. Device will be automated and will use an electric and mechanical system to redirect water to different reservoirs. System will make use of a wide diversity of sensors such as temperature, presence, and volume. Since project is being developed under Mexican investigators, this system is focused in Mexican values. Due to savings made on water bill it is expected to...

Pollution represents one of the major problems of modern cities. Typical indices of extent of this unhealthy phenomenon are the concentration of oxides and particulate matters in the air. Namely Particulate Matter (PM) is responsible for breathing problems and even lung diseases. As a consequence, numerous suitable solutions have been thought in the fields of sensing devices and wireless networks. In the paper, a solution is proposed which aims to use for pollution monitoring the same Advanced Metering Infrastructure (AMI) that is the backbone of smart city projects where measurements of...

This document is a report by Syntraguard, LLC, a high-tech Center for Interdisciplinary Research and Development, that is meant to illustrates a practical means of nanotechnology transfer from academia to industry through partnering. The core competency of Syntraguard is deposition of thin films of DLC (diamond- like carbon) on various client-provided substrates tailored to specific client needs. Because of their superlative characteristics in almost every area for which materials are considered, DLC films offer the best hope for the fabrication of various types of advanced materials and...

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by high blood glucose level and abnormalities in carbohydrate, protein and fat metabolism. The resulting hyperglycemia may lead to irreversible damage, dysfunction and failure of various organs. The objective of this study was to investigate the effects of low, medium and high glycemic index (GI) diets on normal as well as diabetic rats. The three diets were fed to the rats and the biochemical nano- variables and organ histology assessed at the end of the study (90 days). Our findings suggest that it may be possible to...

In the context of noise pollution, this paper aims to demonstrate the importance of uncertainty evaluation in the environmental noise measurement focusing the attention on the variability of the measurand. Managing the result of a comparison between measured value and the maximum levels permitted in law does not involve a straightforward comparison of values, given that such measurement, which can only be an approximation of the value of the measurand, is expressed as an interval. Consequently, it is essential to take into account the uncertainty associated with the measurement. Attention is...

Total potassium (0.84 % to 3.15 %; mean of 1.93 %.) in marijuana buds was determined from the 41 K ( n , γ ) 42 K capture reaction by instrumental neutron activation analysis. The mass fraction of 40 K was derived using the natural isotopic ratios and the activity equation A = λ N used to calculate the activity concentration of 40 K (253 to 946 Bq kg -1 , mean of 581 Bq kg -1 ). Simulated smoking experiments show that over 90% of 40 K is retained in the cigarette ash. Accepted methods of determining effective dose to the body from 40 K inhalation are likely overestimations for both marijuana...

Baseline elemental concentrations in blood samples from healthy Jamaicans were determined using total reflection x- ray fluorescence (TXRF) spectroscopy. The mean concentrations of Cu, Fe, P, Rb, S, Se and Zn of the cohort were found to be 92, 36045, 21930, 199, 147106, 10, 1211 µg/dL respectively. Except for Rb (lower) and Zn (higher) these are similar to values observed worldwide. The mean concentrations of P, S, Fe, Se and Rb in males were significantly different from those in females with males having higher concentrations of all elements determined except Rb. TXRF has demonstrated its...

Neutron activation analysis, using the SLOWPOKE research reactor at the International Centre for Environmental and Nuclear Sciences (ICENS), has been employed for a diverse number of applications from archaeology to forensic science. The SLOWPOKE reactor is known for its highly reproducible flux and neutron activation analysis has several inherent advantages including being chemically non-destructive, having a wide linear range of measurement and being less matrix dependent than comparable techniques. These properties have made this method of analysis appropriate for several studies...

Freeze concentration is a promising water purification technology, specially due to the low levels of energy consumption when compared with other processes such as evaporation. Nevertheless, its development is still at pilot plant scale and more knowledge of the process is needed. One of the important parameters needed for design and control of the process is the growth velocity of the crystal, commonly known as the limit velocity. Above this velocity ice crystals will entrap solids and separation will not be successful. In this work, we describe a non-invasive technique to measure this...
