Modification profiles of bacterial genomes

open access: yesNucleic Acids Research, 1982
DNAs were prepared from twenty-six bacterial species and digested with a variety of restriction endonucleases to determine what modifications the DNAs carry. Several general conclusions could be made: 1) First, in no instance was the DNA of a restriction enzyme.

Analytical algorithm for time-varying meshing stiffness of modified herringbone gear pair

open access: yesXibei Gongye Daxue Xuebao, 2022
This paper jointly uses the slicing method and the potential energy method to propose an analytical algorithm that considers the meshing stiffness of the modified herringbone gear pair and its axial force.

Bond Modification of Carbon Rovings through Profiling

open access: yesMaterials, 2022
The load-bearing behavior and the performance of composites depends largely on the bond between the individual components. In reinforced concrete construction, the bond mechanisms are very well researched. In the case of carbon and textile reinforced concrete, however, there is still a need for research, especially since there is a greater number of ...

Modification of the sterol profile in milk through feeding [PDF]

open access: yesJournal of Dairy Science, 2019
The fortification of milk with phytosterols is an increasingly common practice to enhance the sterol profile and offer consumers potential health benefits. This study investigated whether cattle feed can influence the profile of phytosterols and cholesterol in the milk produced as an alternative to direct fortification of milk.

Relaminarization by Steady Modification of the Streamwise Velocity Profile in a Pipe [PDF]

open access: yesFlow, Turbulence and Combustion, 2018
We show that a rather simple, steady modification of the streamwise velocity profile in a pipe can lead to a complete collapse of turbulence and the flow fully relaminarizes. Two different devices, a stationary obstacle (inset) and a device to inject additional fluid through an annular gap close to the wall, are used to control the flow.

Tooth profile modification of the spur gear based on fuzzy comprehensive decision

open access: yes工程科学学报, 2016
Based on the time-varying mesh stiffness and the Blok flash temperature theory,the influence of tooth profile modification parameters on the load sharing ratio,transmission error and tooth surface flash temperature were systematically analyzed in this ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Influence of Planet Phasing on Quasi-Static Transmission Error in Planetary Spur Gears with Profile Modifications

open access: yesMachines
In a planetary gear system, the planet phasing depends on the number of teeth in the sun and the ring and the number of planets. When the tooth numbers are both multiples of the number of planets, all planets mesh at the same relative position—which is ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...
