Stres Kerja, Kepuasan Kerja, Kesehatan Fisik, Kesalahan Kerja Dan Kecelakaan Kerja Teknisi Pesawat Udara

The study examines job stress, job satisfaction, physical health, work accidents and faulty work. Study was involving 100 aircraft technicians PT. Merpati Nusantara Airlines. Occupational injuries is measured by Safety Related Injuries Scale. Work was measured with a scale error faulty work by the job description of aircraft maintenance division that has been standard. Physical health was measured by Physical Health Questionnaire (PHQ). Job satisfaction was measured by job satisfaction scale developed by researchers. Work stress was measured by Job Stress Survey (JSS). Data occupational accidents, faulty work, physical health, job satisfaction and job stress were analyzed with statistical regression analysis. The analysis showed job stress did not predict an increase in accidents and faulty work. Job stress did not predict decline in physical health and job satisfaction. High and low occupational accidents, faulty work, physical health, and aircraft technician job satisfaction can not be predicted through the high and low job stress

Crown ether-functionalized complex emulsions as an artificial adaptive material platform

Responsive materials capable of autonomously regulating and adapting to molecular recognition-induced chemical events hold great promise in the design of artificial chemo-intelligent life-like soft material platforms. In this context, the design of a synthetically minimal artificial emulsion platform that, regulated by interfacial supramolecular recognition events, is capable to autonomously and reversibly adapt to its chemical environment is reported. The systems exhibit programmed up- and down-regulating capabilities that are realized via selective assembly of synthesized crown ether surfactants onto one hemisphere of anisotropic biphasic emulsion droplets. Dynamic and reversible interfacial host–guest complexation of, for example, metal and ammonium ions or amino acids transduce into interface-triggered morphological reconfigurations of the complex emulsion droplets, which mediate their ability to selectively present, hide, or expand liquid–liquid interfaces. The separate responsive modalities are then used to showcase the utility of such adaptive soft material platforms for a self-regulated uptake and release of metal ions or phase-transfer catalysts, a biomimetic recognition of biomolecules including amino acids, carbohydrates, and antibodies, and for triggered surface-encoded payload release applications

Impfung gegen Pneumokokken überzeugt nicht restlos

Die Pneumokokkenimpfung gehört nicht zu den «beliebtesten» Impfungen. Bis vor kurzem empfahl das Bundesamt für Gesundheit, Risikopatienten jeden Alters und Menschen über 64 Jahre generell zu impfen. Dennoch liegt die Impfrate in Schweizer Hausarztpraxen bei knapp 2%. Eine Studie sucht Gründe

Reversible morphology-resolved chemotactic actuation and motion of Janus emulsion droplets

We report, for the first time, a chemotactic motion of emulsion droplets that can be controllably and reversibly altered. Our approach is based on using biphasic Janus emulsion droplets, where each phase responds differently to chemically induced interfacial tension gradients. By permanently breaking the symmetry of the droplets’ geometry and composition, externally evoked gradients in surfactant concentration or effectiveness induce anisotropic Marangoni-type fluid flows adjacent to each of the two different exposed interfaces. Regulation of the competitive fluid convections then enables a controllable alteration of the speed and the direction of the droplets’ chemotactic motion. Our findings provide insight into how compositional anisotropy can affect the chemotactic behavior of purely liquid-based microswimmers. This has implications for the design of smart and adaptive soft microrobots that can autonomously regulate their response to changes in their chemical environment by chemotactically moving towards or away from a certain target, such as a bacterium.<br

Synthesis of polymer Janus particles with tunable wettability profiles as potent solid surfactants to promote gas delivery in aqueous reaction media

Janus particles exhibit a strong tendency to directionally assemble and segregate to interfaces and thus offer advantages as colloidal analogues of molecular surfactants to improve the stability of multiphasic mixtures. Investigation and application of the unique adsorption properties require synthetic procedures that enable careful design and reliable control over the particles’ asymmetric chemistry and wettability profiles with high morphological uniformity across a sample. Herein, we report on a novel one-step synthetic approach for the generation of amphiphilic polymer Janus particles with highly uniform and tunable wettability contrasts, which is based on using reconfigurable bi-phasic Janus emulsions as versatile particle scaffolds. Two phase-separated acrylate oils were used as the constituent droplet phases and transformed into their solidified Janus particle replicas via UV-induced radical polymerization. Using Janus emulsions as particle precursors offers the advantage that their internal droplet geometry can be fine-tuned by changing the force balance of surface tensions acting at the individual interfaces via surfactants or the volume ratio of the constituent phases. In addition, preassembled functional surfactants at the droplet interfaces can be locked in position upon polymerization, which enables both access toward postfunctionalization reaction schemes and the generation of highly uniform Janus particles with adjustable wettability profiles. Depending on the particle morphology and wettability, their interfacial position can be adjusted, which allows us to stabilize either air bubbles-in-water or water droplets-in-air (liquid marbles). Motivated by the interfacial activity of the particles and particularly the longevity of the resulting particle-stabilized air-in-water bubbles, we explored their ability to promote the delivery of oxygen inside a liquid-phase reaction medium, namely, for the heterogeneous Au-NP-mediated catalytic oxidation of d-glucose. We observed a 2.2-fold increase in the reaction rate attributed to the increase of the local concentration of oxygen around catalysts, thus showcasing a new strategy to overcome the limited solubility of gases in aqueous reaction media

Mehr Hausarztmedizin für HIV-Patienten

Dank der verbesserten Virussuppression hat sich die Lebenserwartung HIV-infizierter Menschen in der Schweiz signifikant verbessert. Was dies für eine optimale Gesundheitsversorgung bedeutet, wurde in einer gemeinsamen Studie von Infektiologen, Hausärzten und Epidemiologen untersucht

Migration pattern of cementless press fit cups in the presence of stabilizing screws in total hip arthroplasty

The aim of this study was to evaluate the initial acetabular implant stability and late acetabular implant migration in press fit cups combined with screw fixation of the acetabular component in order to answer the question whether screws are necessary for the fixation of the acetabular component in cementless primary total hip arthroplasty. One hundred and seven hips were available for follow-up after primary THA using a cementless, porous-coated acetabular component. A total of 631 standardized radiographs were analyzed digitally by the "single-film-x-ray-analysis" method (EBRA). One hundred 'and one (94.4%) acetabular components did not show significant migration of more than 1 mm. Six (5.6%) implants showed migration of more than 1 mm. Statistical analysis did not reveal preoperative patterns that would identify predictors for future migration. Our findings suggest that the use of screw fixation for cementless porous- coated acetabular components for primary THA does not prevent cup migration
