Limitations of Water Resources Infrastructure for Reducing Community Vulnerabilities to Extremes and Uncertainty of Flood and Drought

Debate and deliberation surrounding climate change has shifted from mitigation toward adaptation, with much of the adaptation focus centered on adaptive practices, and infrastructure development. However, there is little research assessing expected impacts, potential benefits, and design challenges that exist for reducing vulnerability to expected climate impacts. The uncertainty of design requirements and associated government policies, and social structures that reflect observed and projected changes in the intensity, duration, and frequency of water-related climate events leaves communities vulnerable to the negative impacts of potential flood and drought. The results of international research into how agricultural infrastructure features in current and planned adaptive capacity of rural communities in Argentina, Canada, and Colombia indicate that extreme hydroclimatic events, as well as climate variability and unpredictability are important for understanding and responding to community vulnerability. The research outcomes clearly identify the need to deliberately plan, coordinate, and implement infrastructures that support community resiliency.Fil: McMartin, Dena W..

Cross Adaptation - Heat and Cold Adaptation to Improve Physiological and Cellular Responses to Hypoxia

To prepare for extremes of heat, cold or low partial pressures of O2, humans can undertake a period of acclimation or acclimatization to induce environment specific adaptations e.g. heat acclimation (HA), cold acclimation (CA), or altitude training. Whilst these strategies are effective, they are not always feasible, due to logistical impracticalities. Cross adaptation is a term used to describe the phenomenon whereby alternative environmental interventions e.g. HA, or CA, may be a beneficial alternative to altitude interventions, providing physiological stress and inducing adaptations observable at altitude. HA can attenuate physiological strain at rest and during moderate intensity exercise at altitude via adaptations allied to improved oxygen delivery to metabolically active tissue, likely following increases in plasma volume and reductions in body temperature. CA appears to improve physiological responses to altitude by attenuating the autonomic response to altitude. While no cross acclimation-derived exercise performance/capacity data have been measured following CA, post-HA improvements in performance underpinned by aerobic metabolism, and therefore dependent on oxygen delivery at altitude, are likely. At a cellular level, heat shock protein responses to altitude are attenuated by prior HA suggesting that an attenuation of the cellular stress response and therefore a reduced disruption to homeostasis at altitude has occurred. This process is known as cross tolerance. The effects of CA on markers of cross tolerance is an area requiring further investigation. Because much of the evidence relating to cross adaptation to altitude has examined the benefits at moderate to high altitudes, future research examining responses at lower altitudes should be conducted given that these environments are more frequently visited by athletes and workers. Mechanistic work to identify the specific physiological and cellular pathways responsible for cross adaptation between heat and altitude, and between cold and altitude, is warranted, as is exploration of benefits across different populations and physical activity profiles

Study of the doubly charmed tetraquark T+cc

Quantum chromodynamics, the theory of the strong force, describes interactions of coloured quarks and gluons and the formation of hadronic matter. Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs, respectively. Particles with an alternative quark content are known as exotic states. Here a study is reported of an exotic narrow state in the D0D0π+ mass spectrum just below the D*+D0 mass threshold produced in proton-proton collisions collected with the LHCb detector at the Large Hadron Collider. The state is consistent with the ground isoscalar T+cc tetraquark with a quark content of ccu⎯⎯⎯d⎯⎯⎯ and spin-parity quantum numbers JP = 1+. Study of the DD mass spectra disfavours interpretation of the resonance as the isovector state. The decay structure via intermediate off-shell D*+ mesons is consistent with the observed D0π+ mass distribution. To analyse the mass of the resonance and its coupling to the D*D system, a dedicated model is developed under the assumption of an isoscalar axial-vector T+cc state decaying to the D*D channel. Using this model, resonance parameters including the pole position, scattering length, effective range and compositeness are determined to reveal important information about the nature of the T+cc state. In addition, an unexpected dependence of the production rate on track multiplicity is observed

ENGAGE. CONNECT. GIVEBACK: Seminar series for Diak Alumni

ABSTRACT Iinge N. Lapp, Ma. Engracia C. Soriano and Aneela Zarish Engage. Connect. Giveback: Seminar series for DIAK Alumni Pages 61 and 6 attachments Published (November 2022) Diaconia University of Applied Sciences Bachelor’s Degree Programme in Social Services Bachelor of Social Services The project-based thesis is written in collaboration with Alumni of the Diaconia University of Applied Sciences. The aim of the thesis was to motivate alumni participation through online seminars in career guidance and mentoring program of the Diaconia University. Mentoring programs can support students in their studies, networking and finding career paths. However, it is challenging to find someone who can guide and motivate to strive harder, especially on voluntary basis. It is difficult to implement a mentoring program without mentors. The goal of the seminar series was to create a platform for final year students and alumni to interact, exchange knowledge, and encourage involvement in the DIAK mentor and career guidance program. There were two objectives in this project. The first objective was to organise two online seminars to promote the existing mentoring and career guidance program to the alumni and the graduating students of the Degree in Social Services. The second objective was to create awareness of the mentoring and career guidance program and encourage the DIAK alumni to participate. The project has followed the developmental phase from planning to evaluation of the project. The project was evaluated by using the SMART evaluation, work life partner evaluation, self-evaluation and participants’ evaluation utilising the feedback forms sent to them after each seminar. It can be said that the project is relevant, timely, and beneficial to DSS students in helping them in looking for work placement, establish the right networks, and find suitable jobs after graduation. Based on the results and evaluation, the project's aims and objectives were accomplished. Thus, the project was beneficial and online seminars have proven to be useful especially when working with alumni and students who do not have much free time. It is recommended for the Work Life partner to continue organising more seminars/gatherings as an efficient and effective way to recruit mentors and mentees for the mentoring programme.
