title: Analysis of skim milk powder deposition on stainless steel tubes in cross-flow

authors: Walmsley, Timothy Gordon

subjects: heat exchanger

abstract: Particulate fouling on the gas side of heat recovery equipment is a common industrial problem. The aim of this study is to characterize the deposition of skim milk powder on a single bare tube in cross-flow. A custom built rig is applied to simulate exhaust air conditions that is experienced in an exhaust exchanger. For a constant airflow rate, increasing particle stickiness resulted in greater deposition coverage around the front of the round and elliptical tubes peaking in the middle, whereas the turned square tube tended to be either clear or covered. Results show that the skim milk powder particle impact angle on the tube, as opposed to the wall shear stress, is an important determinant for deposition. During each test and at the conclusion of each test, which was when fouling reached an asymptote, the amount of deposition coverage and build-up on the tube varied depending on the tube shape, particle stickiness, and air velocity.

title: Geografias do Corpo, Amor e Desejo: Uma Entrevista com Lynda Johnston (Geographies of the Body, Love and Desire: An Interview with Lynda Johnston)

authors: Maria Silva, Joseli

abstract: Lynda  Johnston’s  scientific  trajectory  has  impacted  the  global human geography, Brazil included. For some time, this geographer has  influenced  the  research  developed  by  the  Group  of  territorial studies at the State University of Ponta Grossa. Therefore,interviewing this important, geographer, feminist and queer rsearcher  is  a  great  honor  for  our  group. We  are  honored  to  haveher with us at the Revista Latino­-americana de Geografia e Gênero (Geography  and  Gender  Latin American  Journal),  not  only  for  her capability  and  contribution  to  the  development  of  geography,  but also for admiring her being and way of acting for the dismantling of social inequalities and hierarchies. The combination of her intellectual  competence  and sensitive  and humanitarian character makes Lynda Johnston one of the brightest minds in the contemporary human geography.

title: A walking stick in one hand and a chainsaw in the other: Patients’ perspectives of living with multimorbidity

authors: Signal, Louise

abstract: AIMS: Multimorbidity is common, yet there are major gaps in research, particularly among younger and indigenous populations. This research aimed to understand patients’ perspectives of living with multimorbidity. 

METHODS: A qualitative study of 61 people living with multimorbidity, 27 of whom were Māori and a third aged under 65, from urban and rural regions in New Zealand. Six focus groups and 14 interviews were conducted, recorded, transcribed and analysed. 
RESULTS: For many participants, living with multimorbidity disrupted their ‘normal’ lives, posing challenges in everyday activities such as eating and toileting, working and managing medications. Dealing with the health system posed challenges such as accessing appointments and having enough time in consultations. Cultural competency, good communication and continuity of care from healthcare providers were all valued. Participants had many recommendations to improve management, including a professional single point of contact to coordinate all specialist care. 
CONCLUSIONS: Living with multimorbidity is often challenging requiring people to manage their conditions while continuing to live their lives. This research suggests changes are needed in the health system in New Zealand and elsewhere to better manage multimorbidity thus improving patient’s lives and reducing costs to the health sector and wider society.
