Sustainable Agriculture

The Sustainable Agriculture team is dedicated to developing alternative and sustainable agricultural solutions to alleviate poverty in western Africa. The team is currently working with Sheltering Wings in Yako, Burkina Faso and Trans World Radio in Parakou, Benin. Both clients currently have a working aquaponics system, but the type of system varies between clients. Sheltering Wings has a flood and drain system and Trans World Radio has an ebb and flow system. Throughout this year, our team has focused on reducing power consumption and costs for our clients. The development of the ebb and flow prototype was a consequence of this mission as we reduced power consumption by one pump using a manual siphon. We have also worked towards lowering the costs of water quality testing kits by introducing a Nutrient Film Technique with basil plants. Lastly, we have strived to research best practice methods for fish food making and fish feeding in order to keep the biology of the prototypes healthy. To support present and future clients, the year will conclude with final deliverables for the ebb and flow prototype including an operations and maintenance manual, a construction manual, and a troubleshooting manual.https://mosaic.messiah.edu/engr2021/1016/thumbnail.jp

Village Water Ozonation System

The Village Water Ozonation System (VWOS) team’s core mission statement is to provide economically sustainable and culturally sensitive drinking water solutions for communities, to empower communities with the ability to properly maintain their drinking water supply, and to transform people’s lives by decreasing the occurrences of waterborne diseases. Currently, the VWOS team is partnering with Friends in Action to design and implement two drinking water treatment systems for the community living on Rama Cay, an island in the Bluefields Lagoon on the eastern coastline of Nicaragua. The wells on the island are contaminated with E. coli and other bacteria and contain high levels of salt that cause the water to be unhealthy, distasteful, and corrosive to metal equipment in the system. The team hopes to design a system that will disinfect the water, remove salinity from the well water with a safe and efficient disposal of all byproducts, and decrease corrosion agents. VWOS is partnering with Forward Edge International for the third time (Nicaragua 2009 and Mexico 2016) to design water treatment systems for communities in Oaxaca, Mexico and Kijabe, Kenya. The system for Oaxaca is ready for implementation and awaits availability to travel. The system for Kijabe is in the initial stage of communicating with the client on specifics for the design.https://mosaic.messiah.edu/engr2021/1018/thumbnail.jp

Currently, the VWOS team is partnering with Friends in Action to implement two drinking water treatment systems this summer for the community living on Rama Cay, an island in Nicaragua. The wells on the island have a high salt content and are contaminated with bacteria which makes the water unsafe to drink; therefore, these two systems consist of a Reverse Osmosis unit, a UV light and other filters to ensure clean water. VWOS is also partnering with Forward Edge International to serve Mama Beth\u27s Children\u27s Home in Kijabe, Kenya. Mama Beth\u27s serves approximately 250 children every day but their water source is heavily contaminated with bacteria. VWOS is designing a chlorination system that will provide safe water for the students with plans to implement it in the summer of 2023.

Sustainable Agriculture

The Sustainable Agriculture team is addressing malnutrition through aquaponics. Aquaponics is a soil-free farming method that reduces growing periods and water consumption by 90% compared to traditional methods. The Sustainable Agriculture team works alongside its clients, Youth with a Mission and Trans World Radio, to develop and implement universal and scalable aquaponics prototypes. This year, the team designed and constructed nine working prototypes for a sensitivity analysis. The team also constructed two unique airlift pumps to create alternatives for their clients. They also produced a digital system monitor for tracking temperature, pH, and dissolved oxygen in the aquaponics prototypes for our clients at Youth with a Mission.

Hopes and Fears: Community cohesion and the ‘White working class’ in one of the ‘failed spaces’ of multiculturalism

Since 2001, community cohesion has been an English policy concern, with accompanying media discourse portraying a supposed failure by Muslims to integrate. Latterly, academia has foregrounded White majority attitudes towards ethnic diversity, particularly those of the ‘White working class’. Whilst questioning this categorisation, we present data on attitudes towards diversity from low income, mainly White areas within Dewsbury, West Yorkshire, a town portrayed in media discourse as one of the ‘failed spaces’ of multiculturalism. Drawing on mixed methods research, we present and discuss data that provide a complex message, seemingly confirming pessimistic analyses around ethnic diversity and predominantly White neighbourhoods but also highlighting an appetite within the same communities for greater and more productive inter-ethnic contact. Furthermore, anxieties about diversity and integration have largely failed to coalesce into broad support for organised anti-minority politics manifest in groups such as the English Defence League

Expression of Tissue factor in Adenocarcinoma and Squamous Cell Carcinoma of the Uterine Cervix: Implications for immunotherapy with hI-con1, a factor VII-IgGFc chimeric protein targeting tissue factor

<p>Abstract</p> <p>Background</p> <p>Cervical cancer continues to be an important worldwide health problem for women. Up to 35% of patients who are diagnosed with and appropriately treated for cervical cancer will recur and treatment results are poor for recurrent disease. Given these sobering statistics, development of novel therapies for cervical cancer remains a high priority. We evaluated the expression of Tissue Factor (TF) in cervical cancer and the potential of hI-con1, an antibody-like-molecule targeted against TF, as a novel form of immunotherapy against multiple primary cervical carcinoma cell lines with squamous- and adenocarcinoma histology.</p> <p>Methods</p> <p>Because TF is a transmembrane receptor for coagulation factor VII/VIIa (fVII), in this study we evaluated the <it>in vitro </it>expression of TF in cervical carcinoma cell lines by immunohistochemistry (IHC), real time-PCR (qRT-PCR) and flow cytometry. Sensitivity to hI-con1-dependent cell-mediated-cytotoxicity (IDCC) was evaluated in 5-hrs-⁵¹chromium-release-assays against cervical cancer cell lines <it>in vitro</it>.</p> <p>Results</p> <p>Cytoplasmic and/or membrane TF expression was observed in 8 out of 8 (100%) of the tumor tissues tested by IHC and in 100% (11 out of 11) of the cervical carcinoma cell lines tested by real-time-PCR and flow cytometry but not in normal cervical keratinocytes (<it>p </it>= 0.0023 qRT-PCR; <it>p </it>= 0.0042 flow cytometry). All primary cervical cancer cell lines tested overexpressing TF, regardless of their histology, were highly sensitive to IDCC (mean killing ± SD, 56.2% ± 15.9%, range, 32.4%-76.9%, <it>p </it>< 0.001), while negligible cytotoxicity was seen in the absence of hI-con1 or in the presence of rituximab-control-antibody. Low doses of interleukin-2 further increased the cytotoxic effect induced by hI-con1 (<it>p </it>= 0.025) while human serum did not significantly decrease IDCC against cervical cancer cell lines (<it>p </it>= 0.597).</p> <p>Conclusions</p> <p>TF is highly expressed in squamous and adenocarcinoma of the uterine cervix. hI-con1 induces strong cytotoxicity against primary cervical cancer cell lines overexpressing TF and may represent a novel therapeutic agent for the treatment of cervical cancer refractory to standard treatment modalities.</p

Addressing climate change with behavioral science: a global intervention tournament in 63 countries

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions’ effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior—several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people’s initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P &lt; 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
