Published: August 2022

Food waste and food insecurity present a troubling paradox found across the globe, in local communi­ties, and on college campuses. The Campus Kitch­en at the University of Kentucky (CK) is a student-led, sustainability-focused service organiza­tion in the Feeding America Network that can serve as a local food waste checkpoint in the south­east region of the United States and address com­munity and campus food insecurity through com­munity-build­ing activities. Farm-to-Fork (F2F), a free weekly meal and education program of CK, provides a case study of leveraging existing resources like student volunteers, CK infrastruc­ture, and campus partners to address college food insecurity. In this case study, we evaluate the pilot model of CK and its F2F Program. The data gath­ered consist of the amount of food recovered, the number of meals prepared and distributed, and demographics and behavioral perceptions of col­lege students attend­ing F2F. From August 2018 to December 2019, CK food recovery and meal data were collected and an F2F cross-sectional student survey (N=284) was administered twice. The pro­gram develop­ment, implementation, and evaluation of F2F relies on the social -ecological model (SEM) to capture and highlight the complicated issues of food waste and food insecurity, and the layered approach any initiative addressing such issues must take. Ulti­mately, F2F highlights how programs such as CK can expand their missions of reducing food waste and food insecurity in communities and on college campuses. CK’s economically and envi­ronmentally sustainable practices can be built upon to improve the diversion of food waste and use socially inclu­sive approaches to provide healthy meals and resources to populations experiencing challenges with food insecurity, both on and off campus, as well as educate all those involved. In turn, such an initiative highlights the need to move beyond stopgap measures, such as food pantries, in both community and campus programs targeting food waste and food insecurity.
The Rise of the Machines: Why the future lies with less injurious adaptive ventilation strategies
Authors: Freebairn Ross
Published: August 2022

It has been 60 years since Bendixen, Hedley-White, and Laver described the progressive atelectasis and resultant hypoxemia that resulted from prolonged mechanical ventilation. A proposed solution was to raise the tidal volume (VT) from those recommended by Radford’s nomogram for “proper ventilation” to 10 -15 ml/ kg. It was less than four years later that Acute Respiratory Distress Syndrome (ARDS) was first reported. Since then, clinicians and researchers have been searching for the ideal ventilation strategy to minimise the harm and optimise the outcomes from ventilatory support in the critically ill.

Published: August 2022

Sewage treatment plants (STPs) generate solid by-products that need to be managed safely so as not to compromise the environment and public health. Among these by-products, of special interest is the sludge generated in the primary, biological and physical-chemical treatment units, which concentrates a large amount of the pollutants and contaminants removed during sewage treatment. However, the sludge is also a reservoir of compounds that can be recovered or reused (e.g.: organic matter, phosphorus, and nitrogen), which are of agronomic interest and can be used for the recovery of degraded areas. This technical note (TN), the first of the collection “Valorization and management of solid by-products of sewage treatment. Part A: Sanitization and use of sewage sludge in soil”, presents topics of interest related to modern management of the sludge generated in STPs, with emphasis on the legal aspects and forms of treatment for its transformation into biosolid for use in soils and other possibilities. The other TNs that are part of this collection deepen the topics briefly addressed in this first TN.

Published: August 2022

Alkaline stabilization (AS) is one of the most widespread processes in the world for the sanitization of sludge produced in sewage treatment, although in Brazil it is used by only a few sanitation companies. The fact that an environmentally sustainable destination for sewage sludge is not mandatory, as well as a series of economic, technical and operational factors, end up limiting the AS process application. The increase of AS practices are expected due to the the Brazilian CONAMA Resolution nº 498/2020, which aims to increase the use of biosolids in agriculture and to further deepen technical and operational knowledge related to this practice. This technical note (TN) presents the main forms of the storage and application of lime, as well as the minimum parameters required for designing maturation and curing yards. In this TN, the intrinsic AS costs and best engineering practices used are discussed, in view of reducing possible problems and maximizing its usage throughout the national territory.

Return to Sport Following Anterior Cruciate Ligament Reconstruction: Women’s Field Hockey
Authors: Cotter Ashley
Published: August 2022

Competitive women’s field hockey has evolved through the years, making it a fast-paced sport, requiring high levels of strength, endurance, and cardiopulmonary demands.  While the sport of field hockey continues to grow, so does the number of ACL injuries. Research is lacking in return of female athletes to the sport post ACL reconstruction. The field hockey athlete is required to sprint, pivot, cut, and change directions quickly, while playing in a squat-like position. Rehabilitation guidelines addressing field hockey specific ACL injury must include building lower extremity muscular strength, optimizing neuromuscular control, and improving cardiopulmonary endurance. The challenge for the clinician is to incorporate sport specific elements into the rehabilitation and training to maximize function for return to play, while minimizing risk of reinjury for the field hockey athlete.  This guideline will provide a criterion-based rehabilitation progression with early integration of field hockey specific exercises to assist in the athlete’s multiplanar neuromuscular control and success in return to sport.
Return to Sport Following Anterior Cruciate Ligament Reconstruction: Women's Soccer
Authors: Herget Lenore
Published: August 2022

Soccer is largely recognized as the most popular sport in the world. It involves speed, agility and endurance, requiring its athletes to sprint, explode to the ball, change direction and maintain high thresholds of work for prolonged periods. In the United States, as many as 80,000 high school female athletes experience ACL injuries each year. Females tend to be more at risk for ACL injury for a multitude of reasons including biomechanical, neuromuscular activation patterns, strength imbalances and hormonal factors. Athletes and their families are becoming increasingly aware of this risk and the subsequent risk of not returning to their pre-injury level of play; thus, necessitating both preventative and post injury rehabilitation programs aimed at maximizing function and minimizing subsequent injury. A program that focuses on neuromuscular activation patterns, proprioception and balance training, functional strength, agility, landing techniques and quality of footwork is best for mitigating risk of ACL injuries in female soccer players. This post-surgical ACL reconstruction rehabilitation program for the female soccer player has been divided into five phases, each phase a progression and building upon its preceding phase. The phases range from early post-operative care to late stage, pre-clearance to return to sport guidance and have been constructed based on evidence informed guidelines focusing on maximizing function post operatively in a safe, efficient manner while minimizing risk for re-injury.

Published: August 2022

A demanda dos consumidores por novos produtos lácteos que desempenham efeitos fisiológicos benéficos vem aumentando o interesse na pesquisa por alimentos funcionais. Para um efeito sinérgico na implantação e proliferação de probióticos, a seleção de micro-organismos e adição de prebióticos são condições fundamentais. Assim, os galacto-oligossacarídeos (GOS) vêm sendo considerados como alternativa de grande potencial. Neste contexto, o objetivo deste trabalho foi a elaboração de bebidas lácteas fermentadas com o uso das culturas probióticas Lactobacillus acidophilus, Bifidobacterium spp. e Streptococcus salivarius subsp. thermophilus, adicionadas de prebióticos como GOS presentes no soro de leite e na lactose modificados pela enzima β-galactosidase a fim de obter produtos aceitáveis sensorialmente e um número elevado de células viáveis. Durante o desenvolvimento deste trabalho foram sendo elaboradas várias formulações utilizando análises sensoriais em cada etapa, as quais foram realizadas um levantamento de termos característicos do produto; seleção de um padrão comercial e ajuste dos atributos defeituosos para obtenção de formulação com maior aceitação. Os parâmetros obtidos como resposta demonstram que as formulações possuem características de bebidas lácteas, onde a adição dos GOS influenciou positivamente na qualidade tecnológica e probiótica. Galacto-oligossacarídeos provenientes da síntese enzimática utilizando o soro de leite e a lactose monohidratada podem tornar-se uma alternativa no desenvolvimento de bebidas lácteas funcionais potencialmente simbióticas com aceitação pelo consumidor.

O objetivo do estudo foi avaliar os hábitos alimentares e de vida dos estudantes universitários da Universidade Federal do Pampa (UNIPAMPA) durante o período de pandemia de COVID-19 e verificar se ocorreram possíveis alterações no consumo de alimentos e no estilo de vida desta população. Trata-se de um estudo transversal, de abordagem quantitativa e descritiva. Os participantes responderam um questionário eletrônico criado pelos pesquisadores no formato da plataforma “Formulários Google”. Verificou-se que 48,4% dos pesquisados informaram que a frequência de refeições aumentou durante a pandemia. O consumo de alimentos como verduras, legumes, frutas e leguminosas se manteve para 44,4% dos estudantes durante o período de confinamento, porém 39,3% disseram que aumentaram o consumo de alimentos ricos em açúcar, como doces e sobremesas. Foi observado que 51,4% dos discentes expressaram ganho de peso corporal, sendo que para 44,5% a prática de atividade física diminuiu com a chegada da pandemia. Entre os universitários, o álcool é a substância psicoativa mais consumida e 73,1% referiram consumir bebidas alcoólicas. Entre os acadêmicos, 24,9% apontaram aumento na frequência da aquisição de alimentos prontos para consumo através de serviços de pronta entrega durante o isolamento social. Logo, a associação de hábitos alimentares inadequados com um estilo de vida sedentário podem ser fatores de risco para a instalação de doenças crônicas não transmissíveis.
Encapsulação de compostos fenólicos obtidos de resíduos de alimentos
Authors: SIEBENEICHLER T. J.
Published: August 2022

A produção e o consumo de alimentos vegetais inevitavelmente geram subprodutos e resíduos, como como cascas, talos, bagaços, águas residuais, folhas e sementes. Nos últimos anos, estudos evidenciaram que existe um potencial inexplorado nesses resíduos, como fontes de compostos fenólicos. Os fenólicos são produzidos pelo metabolismo secundário de plantas e apresentam diversas atividades biológicas comprovadas, como propriedades antioxidantes, antimicrobianas, anti-inflamatórias, antivirais e preventivo em diversas doenças relacionadas ao estresse oxidativo. Entretanto, a eficácia desses compostos depende da preservação da estabilidade, bioatividade, bioacessibilidade e biodisponibilidade dos ingredientes ativos. A encapsulação tem sido testada em diversos estudos para melhorar essas características. Várias técnicas de encapsulação foram desenvolvidas e estudadas com diferentes materiais, entre as técnicas podemos destacar secagem por pulverização (spray drying), liofilização, emulsificação, eletrofiação e gelificação ionotrópica. Nesse contexto, esta revisão visa compilar dados sobre as técnicas utilizadas para proteger compostos fenólicos extraídos de resíduos e subprodutos agroindustriais visando aplicações em alimentos.

O cultivo e o beneficiamento de noz-pecan têm crescido exponencialmente a nível mundial nos últimos anos. Esse crescimento deve-se as propriedades nutricionais e antioxidantes presentes nesta cultivar, que se convertem em benefícios para a saúde humana. Para atender ao mercado consumidor, as nozes passam por diferentes etapas de beneficiamento, desde a colheita, descasque (casca externa/verde), secagem, armazenamento e descasque (casca marrom). Durante essas etapas, quantidades consideráveis de co-produtos, incluindo folhas, cascas verdes, amêndoas quebradas e cascas marrons são gerados. Estes co-produtos contém as mesmas propriedades nutricionais das nozes, indicando assim que podem ser utilizados para a elaboração de produtos alimentares e não alimentares, aplicados a diferentes tipos de mercado consumidor. Em face disso, esta revisão bibliográfica aborda tópicos a respeito do histórico da pecanicultura no Brasil e no mundo, benefícios à saúde do consumir, composição físico-química, operações de processamento, co-produtos gerados e potenciais aplicações. Este estudo pode contribuir para difundir ideias inovadoras tornando-se uma alternativa de fonte de renda, tanto para grandes, como pequenos agricultores, além de evitar o descarte inadequado destes co-produtos, contribuindo para tornar uma indústria de beneficiamento de nozes mais sustentável.

Published: August 2022

A demanda dos consumidores por produtos que sejam saborosos, visualmente atrativos e que, ao mesmo tempo visem à saúde e o bem-estar, é um desafio para a indústria de alimentos. Esta pesquisa avaliou a viabilidade da elaboração de hambúrgueres bovino com adição de inulina como ingrediente funcional prebiótico e substituto de gordura. Foram elaboradas três formulações: F1 – com gordura, sem inulina; F2 – com 50% de gordura e 50% de inulina e F3 – com 100% inulina, sem adição de gordura. Os hambúrgueres formulados foram submetidos à avaliação microbiológica, física e físico-química. Todas as amostras atenderam aos padrões microbiológicos estabelecidos pela legislação vigente no Brasil, estando adequadas para consumo. No que se refere aos resultados das análises físico-químicas, os valores de pH e cinzas não apresentaram diferença significativa (p<0,05) entre as amostras. A umidade variou entre 59,99 a 62,19%, já, o teor de proteínas variou de 15,80 a 17,28%, atendendo o regulamento técnico de identidade e qualidade do produto. O teor de lipídios variou de 1,54 a 5,57%, sendo as amostras classificadas como alimento de baixo teor e teor reduzido de gordura, respectivamente. Na análise física comprovou-se que a adição de inulina melhorou a retenção de água nos hambúrgueres. A adição de inulina pode ser uma alternativa para a redução de gordura em hambúrguer bovino, sem prejudicar suas características de qualidade físico-química e microbiológica, além de produzir um produto com possíveis propriedades funcionais.

Published: August 2022

Many authors have recently studied line start permanent magnet assistance synchronous reluctance. This paper presents a method to improve the electromagnetic torque and efficiency of induction motors of 7.5kW-4P (which consists of 36 stator slots and 40 rotor bars) by changing the design of the permanent magnet assistance synchronous reluctance rotors. This means that permanent magnets will be inserted to the squirrel cage induction motors (induction motors). The electromagnetic torque and efficiency of an induction motor is analyzed and compared with that of the line-start synchronous reluctance motor via a finite element analysis. In addition, the influence of position and length permanent magnets on the electromagnetic torque and efficiency of the line-start synchronous reluctance motor is also considered and simulated. The model of this motor Linh is finally designed with four U layered- magnet rotor to verify the developed method. The development of the method is also validated on the practical induction motor.
