Liquid Mixing on Falling Films: Marker-Free, Molecule-Sensitive 3D Mapping Using Raman Imaging.

Following up on a proof of concept, this publication presents a new method for mixing mapping on falling liquid films. On falling liquid films, different surfaces, plain or structured, are common. Regarding mixing of different components, the surface has a significant effect on its capabilities and performance.

Marker-Free, Molecule Sensitive Mapping of Disturbed Falling Fluid Films Using Raman Imaging.

Technical liquid flow films are the basic arrangement for gas fluid transitions of all kinds and are the basis of many chemical processes, such as columns, evaporators, dryers, and different other kinds of fluid/fluid separation units. This publication presents a new method for molecule sensitive, non-contact, and marker-free localized concentration mapping in vertical falling films. Using Raman spectroscopy, no label or marker is needed for the detection of the local composition in liquid mixtures.

Study of Toxic Elements in River Water and Wetland Using Water Hyacinth ( as Pollution Monitor.

The concentration of toxic elements present in surface water of Sutlej River and Harike wetland besides , commonly known as water hyacinth, is estimated employing inductively coupled plasma mass spectrometry (ICP-MS). Toxic elements such as cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), uranium (U), and zinc (Zn) are identified in the river as well as in Harike wetland catchment. Accumulation of elements in different parts of the water hyacinth plant is observed with the roots exhibiting maximum affinity followed by stem and then leaves.

[Factors which influence the position towards euthanasia : Results of a representative survey among older people in Germany].

Background: Until now older adults have not been a target group for surveys regarding their personal attitudes towards euthanasia, although they are closest to chronic illness and death.

Objective: To determine the attitudes of older adults towards euthanasia and controversial topics in the context of illness, euthanasia and care (e. g.

GLI1 progenitor cells in the adrenal capsule of the adult mouse give rise to heterotopic gonadal-like tissue.

As certain strains of mice age, hyperplastic lesions resembling gonadal tissue accumulate beneath the adrenal capsule. Gonadectomy (GDX) accelerates this heterotopic differentiation, resulting in the formation of wedge-shaped adrenocortical neoplasms that produce sex steroids. Stem/progenitor cells that reside in the adrenal capsule and retain properties of the adrenogonadal primordium are thought to be the source of this heterotopic tissue.

In situ microscopy using adjustment-free optics.

In the past years, in situ microscopy has been demonstrated as a technique for monitoring the concentration and morphology of moving microparticles in agitated suspensions. However, up until now, this technique can only achieve a high resolution if a certain manual or automated effort is established for continuous precise focusing. Therefore, the application of in situ microscopes (ISMs) as sensors is inhibited in the cases where unattended operation is required.

Adrenocortical zonation, renewal, and remodeling.

The adrenal cortex is divided into concentric zones. In humans the major cortical zones are the zona glomerulosa, zona fasciculata, and zona reticularis. The adrenal cortex is a dynamic organ in which senescent cells are replaced by newly differentiated ones.

Toying with fate: Redirecting the differentiation of adrenocortical progenitor cells into gonadal-like tissue.

Cell fate decisions are integral to zonation and remodeling of the adrenal cortex. Animal models exhibiting ectopic differentiation of gonadal-like cells in the adrenal cortex can shed light on the molecular mechanisms regulating steroidogenic cell fate. In one such model, prepubertal gonadectomy (GDX) of mice triggers the formation of adrenocortical neoplasms that resemble luteinized ovarian stroma.

[Primary Prevention of Impairments of Mobility Among Nursing Home Residents with Dementia].

The main aim of the study was to investigate the effectiveness of multidisciplinary guidelines in promoting the mobility of people with dementia in 20 German nursing homes. The study was based on a semi-experimental design [pre-post design with intervention (IG) and control group]. The statistical analyses revealed a significantly slower decline of the ability to walk among the residents of the IG than among the controls.

[Prevalence of dementia and medical care in German nursing homes: a nationally representative survey].

Objective: The study aimed to determine the prevalence of dementia and the degree of medical care among residents of nursing homes based on a nationally representative sample of nursing homes in Germany for the first time.

Methods: Based on a probability sample of 609 long-term care institutions in Germany, we drew a sample of 86 facilities by applying a two-stage random procedure. All residents of the participating care facilities were comprehensively assessed by qualified nurses using a standardized Care and Behavior Assessment (CBA).
