Feedback Forwards: how we found new ways to ask our students what they want from the library

A team of Bryant University Librarians are participating in the EXCITE Transformation for Libraries program through the Connecticut State Library. We conducted a series of structured group and one-on-one conversations with students, faculty, and staff in order to learn about how they think and feel about teamwork, the library, and collaboration at the library. We found that students in particular were far more responsive to community sessions than in taking surveys

Combination of cattle urine and dung patches synergically increased nitrous oxide emissions from a temperate grassland under wet conditions.

During grazing, some of the nutrients ingested by cattle are returned to grassland as urine and dung patches and can be lost as greenhouse gases. Sites where cattle congregate are more likely to have overlapping excreta patches favouring enhanced nitrous oxide (N2O) emissions. However, there is no consensus about the magnitude of these or simultaneous methane (CH4) emissions or potential mitigation options. This study investigated the effect of combined cattle dung and urine depositions on N2O and CH4 emissions, compared with emissions from separate depositions, under different weather conditions. Local emission factors (EFs) were then calculated for both gases. A quantitative assessment of published studies was also performed to search for N2O emissions drivers. Two field experiments were performed during two 98-day trials under dry and wet conditions in Tandil, Argentina. Treatments included fresh excreta patches of urine (0.75 L), dung (2.50 kg), dung + urine (2.50 kg + 0.75 L) from Holstein dairy cows, and a control (without excreta). Soil and excreta properties were analysed, and N2O and CH4 fluxes from the patches were measured using the static chamber technique. Patches containing dung were shown to be localised CH4 hotspots. Urine applied to soil, and the addition of urine to dung patches had a negligible effect on CH4 fluxes. Urine, dung and combined patches were found to be localised N2O sources. Adding urine to dung patches under wet weather had a significant synergetic effect (threefold increase) on cumulative N2O emissions compared with the theoretical sum of separate excreta patches. Adding urine to dung patches under dry conditions gave an additive effect on N2O. These findings suggest that preventing overlapping excreta patches under wet conditions can help mitigate N2O emissions from temperate managed grazed pastures. The effect of combining excreta patches was also evident in the EF values obtained. That for CH4 was consistent with the default IPCC value (0.75 g CH4 kg−1 VS), while N2O (EF = 0.03–0.39%) was lower than the updated IPCC 2019 value of 0.6%

JavaScript Dead Code Identification, Elimination, and Empirical Assessment

Web apps are built by using a combination of HTML, CSS, and JavaScript. While building modern web apps, it is common practice to make use of third-party libraries and frameworks, as to improve developers' productivity and code quality. Alongside these benefits, the adoption of such libraries results in the introduction of JavaScript dead code, i.e., code implementing unused functionalities. The costs for downloading and parsing dead code can negatively contribute to the loading time and resource usage of web apps. The goal of our study is two-fold. First, we present Lacuna, an approach for automatically detecting and eliminating JavaScript dead code from web apps. The proposed approach supports both static and dynamic analyses, it is extensible and can be applied to any JavaScript code base, without imposing constraints on the coding style or on the use of specific JavaScript constructs. Secondly, by leveraging Lacuna we conduct an experiment to empirically evaluate the run-time overhead of JavaScript dead code in terms of energy consumption, performance, network usage, and resource usage in the context of mobile web apps. We applied Lacuna four times on 30 mobile web apps independently developed by third-party developers, each time eliminating dead code according to a different optimization level provided by Lacuna. Afterward, each different version of the web app is executed on an Android device, while collecting measures to assess the potential run-time overhead caused by dead code. Experimental results, among others, highlight that the removal of JavaScript dead code has a positive impact on the loading time of mobile web apps, while significantly reducing the number of bytes transferred over the network

The activity of heterotrophic bacteria on the DOM - metal complex affects copper speciation and bioavailability in aquatic ecosystem

Metals are mainly released into the environment by industrial processes where dissolved organic materials (DOM) are present.  This investigation focused on modification of copper species in the presence of aquatic heterotrophic bacteria assemblage and natural dissolved organic materials. Copper dynamics during bacteria growth was evaluated through the determination of dissolved and particulate copper. The results showed a reduction of organic carbon, an increase of free Cu2+ ions followed by adsorbed and internalized copper. This study demonstrated a relevant environmental consequence of heterotrophic bacteria activity related to copper speciation in aquatic ecosystem suggesting that as a result of heterotrophic bacteria activity upon DOM,  more toxic copper species were released into the environment

Application of an enzymatic extract from Aspergillus niger as coagulant for cheddar cheese manufacture

Q2 según Scopus a la fecha de publicaciónThe coagulation of milk by a serin protease from Aspergillus niger NRRL3 was studied by rheology. Cheddar-type cheese was manufactured using 3.5% (v/v) of fungal enzymatic extract and fermentation-produced chymosin was used as control coagulant. Full composition and ripening of both kinds of Cheddar cheese were studied. Differences in the proteolysis of caseins, not only during cheese manufacture but also during ripening, affected cheese composition, texture and peptide profile. Microbial development during ripening was not affected by the coagulant used.Fil: Lombardi, Julia. Consejo Nacional de Investigaciones Científicas y Técnicas.

Numerical simulation of the open-pool reactor coolant system using a multi-domain approach

The computational simulation of large-scale reactors is currently limited by the high computational cost. The system codes allow addressing these problems, although with the well-known loss of local information. The use of coupling domains to reduce the problems looks like a proper alternative to settle this issue. In the present paper, a multi-domain coupling 3-dimensional/0-dimensional method to solve the thermal hydraulics of the TRIGA Mark I IPR-R1 reactor was implemented into a Finite Volume suite. Despite of the broadly literature about coupling methods, even in the nuclear engineering community, most of them manage with different codes in a fully explicit way. In the other hand, the benefit of solve different domain approaches inside the same software is in the use of monolithic algorithms. The proposed method consists on using 3-dimensional full CFD to simulate the reactor pool and 0-dimensional modelling for the external cooling loop. This is made by implementing a set of ad hoc dynamics boundary conditions to model the momentum and energy balances along the pipeline. This strategy was used to perform long-time steady state simulations of the reactor at the design power of 100 kW as well as for the repowering up to 265 kW. The results demonstrated that the core is efficiently cooled at the higher power without need to increase the coolant mass flow rate of the external system. Moreover, two accidental events were simulated: the first case was the Station Black Out at full power of 265 kW. The results indicated that the loss of the external heat sink led to a slow pool heating, but the core remains being cooled by the natural circulation in the pool. In fact, the mass flow rate through the core is only reduced in 15% by the loss of the external loop circulation. Finally, a large-Loss of Coolant Accident for the operational power of 100 kW and keeping the pump running is performed. In this case, the pool is quickly empty if safety systems do not take action and the core is uncovered after 450 s completely losing the core cooling capacity.Fil: Corzo, Santiago Francisco.
