This study explores the use of non-homogeneous hidden Markov models (NHMMs) to forecast streamflows into the Orós Reservoir, located in the State of Ceará, Northeastern Brazil. These models employ hydro-climatic information from a given year to predict the next year inflow. The Orós Reservoir is a key infrastructure in the water resources system of the state, where most rivers present very high temporal variability, which is a challenge for water managers. Streamflow forecast systems at the climate scale (months ahead) can be very useful for the challenging process of water allocation in the region. This paper explores the use of NHMMs to provide a probabilistic one-year ahead forecast of the mean annual flow for the Orós Reservoir. Results based on a forecast verification study based on 60 years of independent data show that NHMMs with two or three hidden states, employing the NINO3 climate index as exogenous variable, provides forecasts with an average value of the continuous ranked probability skill score of about 0.2-0.25, meaning that they are better than climatology. It is also evident that those models performed much better during dry years than during wet years, which may be related to lack of other climate indices. © 2018 American Society of civil Engineers.

We spend much of our time in built environments where we are continually exposed to microorganisms. Within indoor environments on earth, or in environments such as occupied spacecraft, these bacterial and fungal exposures can impact human health. Exposures to microbial growth may be particularly harmful, which is predominantly influenced by moisture availability to dust that contain microbes. This dust is hydroscopic and quickly absorbs water from the air;therefore, when ambient relative humidity levels reach a certain threshold, microbial growth will occur. Different microbial species may be harmful in different ways, but the occurrence of active growth may be the most important factor regardless of taxonomy. In confined environments such as spacecraft elevated moisture conditions are expected due to human activities such as breathing, hygiene routines, food preparation and exercise. These activities have diurnal variations which will influence the water availability for microbial growth over time. NASA has a robust monitoring program for spacecraft that is designed to eliminate or mitigate any potential health effects originating from microorganisms. However, the current standards do not account for microbial growth in spacecraft. Our goal is to propose improved microbial standards for spacecraft based on expected microbial growth due to elevated relative humidity, which is easy to measure. Standards will protect human health and spacecraft integrity. Our hypothesis is that we can determine if growth will be activated based on the number of hours per day spent above a relative humidity threshold. The environment will be considered acceptable if growth is prevented. The first step in creating these standards is to experimentally determine the time required for activation of microbial growth under various moisture conditions. We will consider currently available data collected from incubations performed on house dust from earth to estimate what the activation of mic

A pilot study among farming households in eastern Iowa was conducted between December 2018 and February 2019 to assess human exposure to neonicotinoids. The study area was in a hydrologic setting where groundwater is vulnerable to surface-applied contaminants, and in a region of intense crop and livestock production. In addition to paired outdoor (hydrant) water and indoor (tap) water samples where private wells are being used as the source of drinking water, urine samples were collected before bedtime, during the night, and first morning void from 47 adult male pesticide applicators. Neonicotinoids (NEOs) were detected in 53% of outdoor and 55% of indoor samples, with two or more NEOs in 13% of samples. Clothianidin was the most frequently detected neonicotinoid (outdoor: 53%, maximum (max): 570.6 nanograms per liter [ng/L];indoor: 55%, max: 140.5 ng/L), followed by imidacloprid (outdoor: 13%, max: 3.0 ng/L;indoor: 11%, 29.3 ng/L), and thiamethoxam (outdoor: 6%, max: 16.1 ng/L;indoor: 6%, max: 13.1 ng/L). Human exposure was widely detected in urine samples. A median of 10 different NEOs and/or transformation products (TPs) were detected in urine, with five NEOs detected in all 115 urine samples analyzed, including clothianidin (max: 4.7 micrograms per gram [µg/g]), nitenpyram (max: 1.1 µg/g), thiamethoxam (max: 3.4 µg/g), 6-chloronicotinic acid (max: 7.0 µg/g), and thiacloprid amide (max: 1.5 µg/g). Dinotefuran (max: 2.9 µg/g), imidaclothiz (max: 15.3 µg/g), acetamiprid-N-desmethyl (max: 16.9 µg/g), and N-desmethyl thiamethoxam (max: 3.3 µg/g) were found in > 70% of urine samples. The study results indicate that while the consumption of private well tap water provides a human exposure pathway, the companion urine results provide evidence that diet and/or other exposure pathways (e.g., occupational, house dust) may contribute to exposure more than water contamination. © 2022, The Authors.

Can a robot be a personal dating coach? Even with the increasing amount of conversational data on the internet, the implementation of conversational robots remains a challenge. In particular, a detailed and professional counseling log is expensive and not publicly accessible. In this paper, we develop a robot dating coaching system leveraging corpus from online communities. We examine people’s perceptions of the dating coaching robot with a dialogue module. 97 participants joined to have a conversation with the robot, and 30 of them evaluated the robot. The results indicate that participants thought the robot could become a dating coach while considering the robot is entertaining rather than helpful. © 2020, CC-BY.

Microbial growth may occur in carpet dust when exposed to elevated moisture levels, but it is unknown how diurnal variations in equilibrium relative humidity (ERH) affect this growth. Our goal is to apply the "time-of-wetness" (TOW) concept from fungal growth on drywall to model fungal growth in carpet. Used carpet samples were embedded with dust, placed in an experimental chamber and then the ERH within the chambers was varied from 50% to either 85% or 100% for a period of 0, 6, 12, 18, or 24 hours per day over a two-week period. Quantitative polymerase chain reaction (qPCR) measurements of fungi revealed that for the 85% and 100% samples, growth could be modeled with the standard TOW and activation limited growth curve. These measurements demonstrated that the relative growth rate fit the TOW model with the Pearson Correlation Coefficients of 0.958 for 100% TOW and 0.898 for 85% TOW. DNA sequencing revealed increased abundance of species in the genera Aspergillus and Penicillium, among others, at increased moisture. Ultimately, this data can be used to accurately model fungal growth in housing based on moisture and can be utilized in future public health, policy, and epidemiological models. © 2018 15th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2018.

Traditional building design education in the disciplines of building services, civil engineering, mechanical engineering, etc. focusses on quantifiable factors, i.e. factors which can be subject of calculation, simulation and dimensioning. Since non-quantifiable factors are not part of calculation or simulation models, there is a tendency that they are not adequately considered in education and, as a result, in building planning and operation. In the case of human thermal comfort, building professionals are required to understand the mechanisms and impact of non-quantifiable factors related to human thermal comfort and health, most of which are part of the adaptive thermal comfort concept. This paper identifies the challenges in teaching the concept of adaptive thermal comfort through a collection of lived experiences of the authors. The paper then proposes appropriate intended learning outcomes and teaching methods to equip students with the background knowledge, understanding and skills required to consider human adaptation in their designs. © 2020 16th Conference of the International Society of Indoor Air Quality and Climate: Creative and Smart Solutions for Better Built Environments, Indoor Air 2020.

Crop residues hold promise to alleviate food vs. fuel competition and contribute to biofuel production. However, the impacts of lateral sediment and carbon fluxes caused by residue removal are not fully understood. Here we employ agroecosystem modeling to conservatively estimate lateral sediment and carbon fluxes resulting from partial corn stover removal in the U.S. Midwest. Results show substantial increases in soil erosion resulting from corn stover removal. For example, the area of continuous corn and corn soybean cropping systems exceeding soil erosion tolerance threshold could increase from 1.1 to 13.3% because of 66% corn stover removal. Depending on removal intensity, conservation, and crop rotation, the stover removal-induced increases in eroded soil organic carbon is equivalent to 3.9-12.5 gCOe MJ, which is comparable to other components of the life cycle impacts of corn stover-derived biofuel. Our findings highlight the need to consider the soil erosion and lateral carbon fluxes impacts of corn stover removal in designing supply chains for cellulosic biofuel production.

Poultry wastes (PW) and palm oil mill effluents (POME) are thought to be promising starting materials for biogas production. In the present study, the optimization of biomethanization process from co-digested (PW) and POME was investigated. To assist digestion, samples were sun-dried, ground, and mixed with water to form slurry. The central composite design was used in the experimental design, while the desirability function was applied in the process optimization of the co-digestion process. The interactive effects of temperature, pH, and hydraulic retention time were equally studied. The results showed a high co-efficient of determination (R 2 ) value of 0.9920. Also, the predicted and experimental values obtained were 4377.71 ml and 4379.01 respectively, while the optimum conditions obtained were 45 °C, 8.00 and 15 days for temperature, pH, and hydraulic retention time, respectively. This finding shows that the proposed technique is effective and robust in predicting biomethane generation from co-digested POME and PW.
