Addition of biochar produced through thermal decomposition of biomass has been seen as a strategy to improve soils and to sequester carbon （C）, but wide scale implementation of the technology requires to devise innovative profitable solutions. To develop biochar utilisation with an integrated system approach, an innovative program was implemented in 2012 on a 53-ha farm in Western Australia to determine the costs and benefits of integrating biochar with animal husbandry and improvement of pastures. Biochar was mixed with molasses and fed directly to cows. The dung-biochar mixture was incorporated into the soft profile by dung beetles. We studied the changes in soil properties over 3 years. Biochar extracted from fresh dung and from the soil to a depth of 40 cm was characterised. A preliminary financial analysis of the costs and benefits of this integrated approach was also undertaken. The preliminary investigation results suggested that this strategy was effective in improving soil properties and increasing returns to the farmer. It was also concluded that the biochar adsorbed nutrients from the cow＇s gut and from the dung. Dung beetles could transport this nutrient-rich biochar into the soil profile. There was little evidence that the recalcitrant component of the biochar was reduced through reactions inside the gut or on/in the soil. Further research is required to quantify the long-term impact of integrating biochar and dung beetles into the rearing of cows.

Animals communicate information within their environments via visual, chemical, auditory, and/or tactile modalities. The use of each modalityis generally linked to particular brain regions, but it is not yet known whether the cellular morphology of neurons in these regions has evolved in association with the relative use of a *** investigated relationships between the behavioral use of communication modalities and neural morphologies in six lizard species. Two of these species （Anolis carol# nensis and Leiocephalus carinatus） primarily use visual signals to communicate with conspecifics and detect potential prey, and two （Aspidoscelis gularis and Scincella lateralis） communicate and forage primarily using chemical signals. Two other species （Hemidactylus turcicus and Sceloporus olivaceus） use both visual and chemical signals. For each species, we performed beha- vioral observations and quantified rates of visual and chemical behaviors. We then cryosectioned brain tissues from 9-10 males of each species and measured the soma size and density of neurons in two brain regions associated with visual behaviors （the lat- eral geniculate nucleus and the nucleus rotundus） and one region associated with chemical behaviors （the nucleus sphericus）. With analyses conducted in a phylogenetic context, we found that species that performed higher rates of visual displays had a denser lateral geniculate nucleus, and species that used a higher proportion of chemical displays had larger somas in the nucleus sphericus. These relationships suggest that neural morphologies in the brain have evolved convergently in species with similar communication behaviors .

A reactive stream stabilization (RS2) system based on aluminum as the adsorbent and garden mulch as the organic matter source was designed to minimize release of agricultural nonpoint source pollutants and installed along the bank of the Little Bogue Creek, MS in 2008. The scope of this research was to design, install and assess the performance of a field scale RS2 structure based on results from previous lab scale studies. Concentrations of alum and total organic carbon (TOC) in the RS2 test barrier and surrounding area were measured to evaluate design parameters of RS2 and the removal effectiveness was examined from soils and monitoring wells that were sampled in 2009. The mean concentration of Al from the reactive barrier was 2.1 mg/g and organic matter from the monitoring wells was 4.7 mg/L, values significantly greater than the surrounding area (p < 0.05). Soil Mehlich-3 P and total phosphorus (TP) were decreased by 55% and 30%, and 40% of the TN and 51% of the nitrate in the ground water were removed through the RS2. The design objectives have been satisfied with the installed RS2 system and the initial sampling data shows effective nutrient removal.

Objective: Endotracheal intubation (ETI) is a life-saving emergency procedure, but it is a complex skill that is difficult to teach. Recent studies have shown that video laryngoscopy is effective in teaching ETI to learners at various levels of medical expertise;however, it has proven to be costly and provides images of inconsistent quality. In this educational proof of concept feasibility convenience sample pilot study, we aim to explore and compare the effectiveness of using modified Google Glass? (GG) and GoPro? (GP) technologies to visualize and teach ETI to critical care physicians in the austere medical environment of a low-income country. We propose, based on our findings, that this inexpensive technology could teach lifesaving ETI to pre-hospital providers in the austere medical environment, medical students, rural emergency physicians, critical care physicians in low-income countries, far forward military medical providers, and other learners. Methods: A case series of twenty-five patients, five in the United States (US) at Memorial Hospital in South Bend, IN and twenty at Saint Luc’s Hospital in Port Au Prince, Haiti, is presented. These patients were collected from November 1st 2015 through February 1st of 2016. The anesthesiologist and the emergency physicians in the United States utilized GG to intubate five patients in the US prior to the twenty patients intubated during two separate trips to Haiti. On the two separate trips to Haiti, the GG was trialed and modified to obtain better exposure. These adaptations resulted in the final collection of twenty patients studied with the adapted GG system and GP. Physicians graded airway visualization based on LEMON and Cormack-Lehane scores. Previously published parameters for the assessment of failed intubation risk and passage of the cords were used as data points for analysis using a Likert-Scale analysis for each parameter. The data were analyzed by averages of Likert-Scale scoring with their respective sta
