Capturing Hydrophobic Trifluoroiodomethane in Water into an M 4 L 6 Cage

2016

Synthetically important trifluoroiodomethane (CF3I) was trapped in water by using a metal–organic supramolecular anionic cage. Under ambient conditions, nearly 1:1 encapsulation of the hydrophobic, gaseous CF3I substrate with the cage was observed, and its binding constant was calculated by relative comparison with benzene encapsulation.

Welfare status of cage farmed European sea bass (Dicentrarchus labrax): A comparison between submerged and surface cages

2011

Abstract Submersible sea-cages represent an alternative method to standard surface-based cages, and could help solve several production problems that exist in surface-based farming, such as heavy storms, algal and jellyfish blooms and attacks by predators. In this study, we investigated growth, haematological, biochemical and immunological parameters of European sea bass ( Dicentrarchus labrax ) farmed in surface and submersible cages, to compare the physiological status under different rearing conditions. In addition, we evaluated the use of erythrocyte HSP70 levels as a biomarker of fish welfare. The study was conducted in two submerged and two surface cages filled with D. labrax . No sig…

New dynamics in doped fiber laser cavity : self organization and scale laws

2017

Non-linear effects, which depend essentially on the intensity of the electric field of the wave and the guide, are essential for the generation of pulse regimes in doped fiber lasers. The Kerr effect, which occurs regardless of the propagation and pumping energy, will generate the phenomenon of phase auto modulation (SPM), which will result in a spectral expansion. The SPM can also be seen in the interaction between the two waves that propagate along the slow and fast axes of the guide (XPM). In a passive uniform guide, this self-phase modulation in combination with the chromatic dispersion of the guide can lead to the soliton pulse, but this framework must be largely overcome to address pu…

Long cavity ring fiber mode-locked laser with decreased net value of nonlinear polarization rotation

2019

We investigate a new configuration of a mode-locked fiber laser by using a nonlinear polarization rotation-based design to generate soliton pulses with low repetition rate. Unlike with previously reported configurations, we introduce a Faraday mirror after the first half of the cavity length to counteract the nonlinear polarization rotation effects. The total cavity length is 437 m including a 400-m long twisted SMF-28 fiber. The fiber was twisted to cancel the linear birefringence and to ensure that the polarization ellipticity is not altered as the pulse travels along the fiber. The strict control of polarization yields a stable relation between the polarization state of the pulses propag…

Preoperative Considerations on the Thorax: Anatomy and Surgical Landmarks

2020

The thoracic wall is the higher part of the thorax consisting of a musculoskeletal structure including the mediastinum, the pleuropulmonary cavities, viscera, lymphatic, vascular, and nervous structures. Its dimensions are influenced by age, gender, and life style including physical training. It changes constantly in shape and size according to respiration: Generally, males show an abdominal pattern while females have usually a thoracic respiration pattern. The anatomy of the chest differs between men and women, with considerable variations among different ages and races. The skin is thicker in male than in female. In the male thorax, hair is frequently present and the mammary glands are un…

Three-dimensional geometric morphometrics of thorax-pelvis covariation and its potential for predicting the thorax morphology: A case study on Kebara…

2020

The skeletal torso is a complex structure of outstanding importance in understanding human body shape evolution, but reconstruction usually entails an element of subjectivity as researchers apply their own anatomical expertise to the process. Among different fossil reconstruction methods, 3D geometric morphometric techniques have been increasingly used in the last decades. Two-block partial least squares analysis has shown great potential for predicting missing elements by exploiting the covariation between two structures (blocks) in a reference sample: one block can be predicted from the other one based on the strength of covariation between blocks. The first aim of this study is to test w…

Cell type-specific circuits of cortical layer IV spiny neurons

2003

Sensory signal processing in cortical layer IV involves two major morphological classes of excitatory neurons: spiny stellate and pyramidal cells. It is essentially unknown how these two cell types are integrated into intracortical networks and whether they play different roles in cortical signal processing. We mapped their cell-specific intracortical afferents in rat somatosensory cortex through a combination of whole-cell patch-clamp recordings and caged glutamate photolysis. Spiny stellate cells received monosynaptic excitation and inhibition originating almost exclusively from neurons located within the same barrel. Pyramidal cells, by contrast, displayed additional excitatory inputs fr…
