The oil and gas industry is known for its volatile boom and bust cycles, and this has a particularly strong effect on offshore platforms, which are substantial investments that do not always succeed in generating profit. To generate value and remain competitive in the offshore sector, operators must ensure that their ... |
This paper designs a new observer of the attitude fusion algorithm which is applicable to small unmanned aerial vehicles (UAVs) using MEMS sensors in non-stationary environment. When the UAV is under accelerative environment, the accelerometer degrades the accuracy of estimated attitude. Attitude heading reference sys... |
Gluconeogenic conditions, such as administration of triamcinolone or alloxan diabetes, cause the following changes in the molecular structure and properties of rabbit liver fructose 1,6-bisphosphatase (D-fructose-1,6-bisphosphate 1-phosphohydrolase, EC 3.1.3.11): (1) the appearance of traces (about 10%) of a lighter su... |
Although histochemical staining has been believed to inhibit the DNA amplification reaction, no previous study has systematically evaluated the influence of histochemical staining on downstream molecular assays. To evaluate an influence of H&E staining on DNA testing, we isolated DNA from 10 unstained, 10 hematoxylin-s... |
This contribution looks at how great-city working life and business are increasingly oriented towards the activities in high-added-value trades and 'opaque' markets, where face-to-face interactions are still a vital part of what they offer. It argues that whilst the pandemic has undoubtedly |
hit hard, its longer-term impacts should not be over-stressed: the world cities look set for continued dominance, centrality and scale will still be vital for the smaller conurbations, and the prospects for more peripheral locations may not be as positive as proponents of ex-urban flight might |
anticipate.Responses of active and inactive plasma renin and changes in urinary kallikrein and plasma prekallikrein to various conditions in normal subjects. |
Little is known about changes in inactive plasma renin in various conditions or the in vivo activation mechanism of inactive renin. The effects of various factors known to stimulate or suppress renin release on active and inactive PRA were examined in normal subjects. Inactive PRA was determined as the difference betwe... |
Kinetic experiments of labelling in vivo with [14C]orotate of cellular free UMP and/or UTP, nucleolar, nucleoplasmic and cytoplasmic rRNA in normal and 12 h-regenerating rat liver were performed.

Extract of Linum usitatissimum seeds was analyzed by ESI-MS and ESI-MS/MS. The analysis confirms the presence of previously reported cyclolinopeptides: CLA (c(Pro-Pro-Phe-Phe-Leu-Ile-Ile-Leu-Val) and CLB (c(Pro-Pro-Phe-Phe-Val-Ile-Met-Ile-Leu)). Cyclolinopeptides CLD and CLE, which contain methionine oxide, were detect... |
A posterior intercostal approach is commonly used for percutaneous access to the upper poles of the kidney. However, the safety of this approach with respect to puncturing the intervening lung, pleura, liver, and spleen with the needle has been inferred only from a small series of patients without regard to the degree ... |
In this paper, we generalize monotone operators, their resolvents and the proximal point algorithm to complete CAT(0) spaces. We study some properties of monotone operators and their resolvents. We show that the sequence generated by the inexact proximal point algorithm $\unicode[STIX]{x1D6E5}$ -converges to a zero of ... |
Expressions are derived for the sixteen wave front aberration coefficients of a single grating. These give the wave aberrations to the fourth order for a plane symmetric grating system. The contributions from each mirror and grating can be added to give the aberrations in the final image. Problems encountered with inte... |
Structured learning algorithms usually involve an inference phase that selects the best global output variables assignments based on the local scores of all possible assignments. We extend deep neural networks with structured learning to combine the power of learning representations and leveraging the use of domain kno... |

Our study sample included 6,862 children aged 0-19 years, assessed for ASD (61% diagnosed with ASD) between 2010-2017 in British Columbia, Canada. ASD was diagnosed by a provincially qualified specialist and the assessment included the use of the Autism Diagnostic Observation Schedule (ADOS-2) and Autism Diagnostic In... |
The overall prevalence of language impairment in children diagnosed with ASD (n = 1820, 44%) was similar to those not diagnosed (n = 1199, 44%). There was more mixed receptive/expressive (80% vs 65%) and less expressive only (22% vs 29%) language impairment in children diagnosed with ASD than without. Looking only at ... |
In children who have been referred for an ASD assessment, the prevalence of language impairment is similar in those with and without ASD. Children with ASD are more likely to be diagnosed with mixed language impairment than expressive only language impairment, although this difference may in part be due to challenges ... |

BACKGROUND |
The working posture affects the peripheral venous circulation, although the current literature does not report any correlation between working posture and the abnormalities of the jugular veins flow. The purpose of this preliminary research is to study, in female workers, the prevalence of Venous Compressive Syndrome (... |
METHODS |
We studied a sample of female workers with ECD (n=128), in supine and upright position divided into subgroups according to the obliged posture maintained during working hours: group A, seated work (n = 61; 47.7%); group B, standing work (n = 41; 32.0%); group C, mixed (both standing and seated work) (n = 26; 20.3%). Th... |
RESULTS |
Group A and group C did not show any White Compression in orthostatic and clinostatic position. The 9.75% (p = 0.0125) of Group B had a White Compression in orthostatic position: two female workers on the left side (4.9%) and two female workers on the right side (4.9%). |
CONCLUSIONS |
We conclude that there is a risk of jugular compression blocks in female workers exposed to prolonged upright posture. Yet there is no longitudinal study that identifies the White Compressions as etiology of a chronic neurodegenerative disease. The authors hope that some wider studies can confirm the prevalence of thes... |
It is a well-established finding in the literature that immigrants make ambitious educational choices. Once controlling for prior achievement and socioeconomic status, children of immigrants are more likely than natives to switch to the more demanding educational tracks. However, less is known about whether immigrants... |
There is some evidence that type I and type III collagens may be present in the same fibril. In order to demonstrate this, double labeling immunofluorescence microscopy and immunoelectron microscopy were performed with antibodies directed against the collagen molecule and the aminopropeptide domains of type I and type ... |
Lately, there had been keen explorations into a new type of novel waveguide that enjoys, over a wide bandwidth, the desirable trait of having only one TEM mode propagating along just the direction of a metallic rectangular ridge embossed onto a wall of a parallel-plate waveguide and existing only within the resultant r... |
Older adults are more likely to be restrained during hospital stays than are younger individuals.
