Effects of leg fatigue due to exhaustive stair climbing on gait biomechanics while walking up a 10˚ incline – implications for evacuation and work safety

This biomechanics study explored stride length (SL), duration (SDN), and gait ground reaction forces (GRFspeak), required coefficient of friction (RCOFpeak), joint angle (anglepeak, anglemin), angular velocities (angvelx peak), angular accelerations (angaccx peak), muscle electromyography (EMG) during the dominant leg stance phase (SP) following an exhaustive stair ascent for evacuation. Data were

Breast cancer risk factors and survival by tumor subtype : pooled analyses from the Breast Cancer Association Consortium

BACKGROUND: It is not known if modifiable lifestyle factors that predict survival after invasive breast cancer differ by subtype.METHODS: We analyzed data for 121,435 women diagnosed with breast cancer from 67 studies in the Breast Cancer Association Consortium with 16,890 deaths (8,554 breast cancer-specific) over 10 years. Cox regression was used to estimate associations between risk factors and

The seaweed experience: exploring the potential and value of a marine resource

The article addresses the broader relationships between seaweed and algae as a marine resource, destination development, and sustainability. In many European countries, an industry around seaweed has emerged, ranging from high-end restaurants that provide their customers with local, seasonal and sustainableingredients, to entrepreneurs offering “harvest your own seaweed”-tours. In this explorative

Nasal symptoms increase the risk of snoring and snoring increases the risk of nasal symptoms. A longitudinal population study

Purpose: Humans have a preference for nasal breathing during sleep. This 10-year prospective study aimed to determine if nasal symptoms can predict snoring and also if snoring can predict development of nasal symptoms. The hypothesis proposed is that nasal symptoms affect the risk of snoring 10 years later, whereas snoring does not increase the risk of developing nasal symptoms. Methods: In the co

Higher stand densities can promote soil carbon storage after conversion of temperate mixed natural forests to larch plantations

Soil carbon (C) reservoirs held in forests play a significant role in the global C cycle. However, harvesting natural forests tend to lead to soil C loss, which can be countered by the establishment of plantations after clear cutting. Therefore, there is a need to determine how forest management can affect soil C sequestration. The management of stand density could provide an effective tool to con

Assessing the use of a portable time-geographic diary for detecting patterns of daily occupations

Background: A time-geographic diary approach is of interest in occupational therapy due to the inclusion of the diarist’s subjective experiences. There are several methods for detecting doing in time, but details needed for analysis are still lacking. The smartphone application POrtable Diary Data collector (PODD), a 24-hr diary based on the time-geographic diary has recently been introduced. Aim:

Generalized Two-Magnitude Check Node Updating with Self Correction for 5G LDPC Codes Decoding

The min-sum (MS) and approximate-min* (a-min*) algorithms are alternatives of the belief propagation (BP) algorithm for decoding low-density parity-check (LDPC) codes. To lower the BP decoding complexity, both algorithms compute two magnitudes at each check node (CN) and pass them to the neighboring variable nodes (VNs).In this work we propose a new algorithm, ga-min*, that generalizes the MS and

From antagonists to allies? Exploring the critical performativity of alternative organization

In this introduction to the special issue on critical performativity and alternative organization we provide a brief historico-theoretical sketch of the key concepts involved and point to ongoing pertinent debates in the field of critical management studies. We also present the articles included in the issue, which all explore aspects of how critical performativity and alternative organization may

Demonstration of two group‐specific TSTAs in adenovirus‐induced tumors

Infection of mice and rats with any one of five tested human adenovirus types belonging to groups A and B (types 3, 7, 12, 18 and 31) induced an immunity to the TSTAs of type 12 tumors as detected by the colony inhibition (CI) test. No immunity was found against an adenovirus type 1 tumor. Two adenovirus types belonging to group C (types 1 and 5) were similarly tested and found to induce a clear‐c

PM 2/21 : Methods for assessing the effects of plant protection products on biodiversity

Lunds universitet fick i uppdrag av Kemikalieinspektionen att kartlägga och beskriva ansatser till metoder som bedömer indirekta effekter av växtskyddsmedel på individer och populationer och studier som utvärderar om nuvarande riskbedömningsmetoder är tillräckliga för att bedöma direkta effekter av växtskyddsmedel på biologisk mångfald. Uppdraget utfördes i två delar. För det första inventerade viLund University was commissioned by the Swedish Chemicals Agency to map and describe emerging methodologies that assess the indirect impact of plant protection products on nontarget organism individuals and populations, and studies that evaluates if current risk assessment methodologies are sufficient to assess direct effects of plant protection products on biodiversity. The commission was perform

Effect of BCG and allogeneic tumour cells on adenovirus type 12 tumorigenesis in mice

HAMSTERS and mice inoculated at birth with tumour viruses have been used in studies of the prophylactic effects of various treatments during the latent period. The incidence of primary tumours in hamsters infected at birth with SV40 is reduced if the virus is inoculated during the latent period1-3. Similar administration of adenovirus type 12 also inhibited the induction of tumours by SV404; this

Accelerated inflammatory aging in Alzheimer’s disease and its relation to amyloid, tau, and cognition

It is unclear how pathological aging of the inflammatory system relates to Alzheimer’s disease (AD). We tested whether age-related inflammatory changes in cerebrospinal fluid (CSF) and plasma exist across different stages of AD, and whether such changes related to AD pathology. Linear regression was first used model chronological age in amyloid-β negative, cognitively unimpaired individuals (Aβ− C

A secure procedure for early career scientists to report apparent misconduct

Early career scientists sometimes observe senior scientists engage in apparent scientific misconduct, but feel powerless to intervene, lest they imperil their careers. We propose a Secure Reporting Procedure that both protects them, when pursuing those concerns, and treats the senior scientists fairly. The proposed procedure is, we argue, consistent with the ethical principles of the scientific co

Role of hydroxylation for the atomic structure of a non-polar vicinal zinc oxide

From the catalytic, semiconducting, and optical properties of zinc oxide (ZnO) numerous potential applications emerge. For the physical and chemical properties of the surface, under-coordinated atoms often play an important role, necessitating systematic studies of their influence. Here we study the vicinal ZnO(10 1 ¯ 4) surface, rich in under-coordinated sites, using a combination of several expe

A time-frequency-shift invariant parameter estimator for oscillating transient functions using the matched window reassignment

In this paper we present the matched window reassignment method, generalizing the results to complex valued signals in multiple dimensions. For an oscillating transient signal with an envelope shape described by an arbitrary twice differentiable function, the reassigned spectrogram, with a matched window, concentrates all energy into one single time-frequency point. An estimator for the parameters

Muscular loading affects the 3D structure of both the mineralized rudiment and growth plate at early stages of bone formation

Fetal immobilization affects skeletal development and can lead to severe malformations. Still, how mechanical load affects embryonic bone formation is not fully elucidated. This study combines mechanobiology, image analysis and developmental biology, to investigate the structural effects of muscular loading on embryonic long bones. We present a novel approach involving a semi-automatic workflow, t

Swedish daylight regulation throughout the 20th century and considerations regarding current assessment methods for residential spaces

Daylight availability for buildings has been an integral part of architecture since ancient times, yet for the vast majority of countries, criteria for daylight provision were not normative until the 20th century. This article examines the case of Sweden, where the term “daylight” first appeared in regulations in 1960, and assesses the daylight compliance of multi-dwelling buildings before and aft
