Structured Interdisciplinary Bedside Rounds (SIBR) is a standardized, team-based intervention for hospitals to deliver high quality interprofessional care. Despite its potential for improving IPC and the workplace environment, relatively little is known about SIBR's effect on these outcomes. Our study aimed to assess the fidelity of SIBR implementation on an inpatient medicine teaching unit and its effects on perceived IPC and workplace efficiency. We conducted a quasi-experimental study with 88 residents and 44 nurses at a large academic medical center and observed 1308 SIBR encounters over 24 weeks. Of these 1308 encounters, the bedside nurse was present for 96.7%, physician for 97.6%, and care manager for 94.7, and 64.7% occurred at the bedside. Following SIBR implementation, perceived IPC improved significantly among residents (93.3% versus 67.9%, p <.024) and nurses (73.7% versus 36.0%, p <.008) compared to before implementation. Moreover, residents perceived greater workplace efficiency operationalized as being paged less frequently with questions by nurses (20.0% versus 49.1%, p =.01). No statistically significant improvements were reported regarding burnout, meaning at work, and workplace satisfaction. Our implementation of SIBR significantly improved perceived IPC and workplace efficiency, which are two important domains of healthcare quality. Future work should examine the impact of SIBR on patient-centered outcomes such as patient experience. [ABSTRACT FROM AUTHOR]

In many parts of world, there is still a tradition of using herbal drugs to combat various diseases & infections. Sibr is one of the essential components of Unani system of medicine and used by Unani physicians due to it’s a lot of medicinal properties since ancient time. It is commonly called Aloe-vera and belongs to the Lilicaceal family. It is a cactus like herb and grows in hot and arid environment. Unani physicians have been using this drug as a laxative, purgative (phlegm/bile), brain tonic, stomach tonic, liver tonic, emmenogogue, antiinflammatory, blood purifier, antibacterial, and carminative agent. Hence, this drug having a vital place in Unani system of medicine and text. It is also use to reducing Low density Lipoprotein, increasing High density Lipoprotein, minimizing frost-bite injury, reducing blood glucose level, fighting against Acquired Immuno Deficiency Syndrome (AIDS), allergies, and boosting immune system. This article was designed to lime light the Aloe barbadensis by describing its brief toxicology, contraindications, traditional, therapeutic and others uses. [ABSTRACT FROM AUTHOR]

Highlights • SIBR did not affect stroke patients' length of stay and incidence of adverse events. • No benefits of SIBR in a stroke unit with regards to patient and staff satisfaction. • Limited gains of implementing costly SIBR in a well organised unit. Abstract Given reported favourable outcomes of accountable care unit models of health care delivery (Taylor et al., 2017; Stein et al., 2015; Kara et al., 2015), the Clinical Excellence Commission of NSW has embraced "In Safe Hands" (ISH) to enhance coordination of care. ISH embraces the structured interdisciplinary bedside round (SIBR) component, for which reported outcomes include reduced length of stay (Taylor et al., 2017; Stein et al., 2015; Kara et al., 2015), possible reduction in overall costs of care (Kara et al., 2015), and enhanced patient and staff satisfaction (O'Leary et al., 2011). It is not yet clear whether the benefits of such a model are translatable to the Australian Health Care System (Hunyh et al., 2016) and/or established units with an already strong multi-disciplinary approach to patient care. The purpose of this prospective cohort study of 200 participants was to assess the effect(s) of implementation of ISH in a stroke unit of a tertiary hospital in Sydney, Australia. Data on length of stay, re-admission rates, adverse events, as well as patient and nursing satisfaction, were collected pre and post implementation. There was no significant difference in length of stay in median days (5 (IQR 2–7) versus 4 (IQR 2–6), P = 0.55) or incidence of adverse events (10% versus 12%, P = 0.82). Stroke outcome disability scores were not affected by the intervention. There were no significant differences overall in reported patient and nursing satisfaction. Implementation of the ISH program cost approximately AUD$ 1805/week (USD$ 1365) in wages. The ISH program was a costly intervention of limited benefit in a well-established acute stroke unit. We here discuss potential reasons for the failure of this intervention to achieve its primary aim in this setting. [ABSTRACT FROM AUTHOR]

ABSTRACT High impact polystyrene (HIPS) resins were obtained with in situ bulk polymerization toughened by styrene-isoprene-butadiene terpolymer rubber (SIBR). SIBR prepolymer was prepared through selective polymerization of styrene (St), isoprene (Ip), and butadiene (Bd) in St with [Nd]/[Al]/[Cl] catalyst. Nd-based catalyst exhibited more favorable activity toward conjugated diene other than St, resulting in St solution of random SIBR with high cis-1,4 stereoregularity and low St content, which was directly exposed to the free radical polymerization of St to generate HIPS. Effect of toughened rubber and the initiators [difunctional (D2) and trifunctional (T3)] were examined to attain HIPS possessing mechanical properties as follow: impact strength, 0.9-24.8 kJ/m2; tensile strength, 16.0-27.5 MPa; and elongation at break, 7.4-107.0%. Increasing SIBR matrix in HIPS improved the impact strength and decreased tensile strength. The fracture surface morphologies of HIPS specimens were studied by notched impact tests and scanning electron microscopy (SEM), illustrating that the incremental SIBR matrix presented synergistic toughening effect of crazing to enhance the ductile fracture behavior. © 2016 Wiley Periodicals, Inc.

Hydrogenated styrene-isoprene-butadiene rubber (HSIBR) was prepared through the hydrogenation reaction of self-prepared styrene-isoprene-butadiene rubber using a Ziegler-Natta type catalyst prepared with nickel naphthenate (Ni) and aluminum triisobutyl (Al). The precursors and corresponding hydrogenated polymers were characterised using size exclusion chromatography, proton nuclear magnetic resonance (1H NMR) spectroscopy, differential scanning calorimetry and thermal gravimetric analysis. The effects of various reaction parameters on the level of hydrogenation, calculated from 1H NMR spectroscopy, were investigated in the current paper. A maximum of 98% hydrogenation was obtained under the following conditions: Al/Ni molar ratio, 6; catalyst amount, 3 mg Ni per g of polymer; time, 3 h; temperature, 60°C; H2 pressure, 4 MPa and polymer concentration, 10 wt.%. Moreover, a different SAE 5W-30 multigrade oil (5 CST hydroisomerisation dewax base oil) was formulated using HSIBR samples as viscosity index improvers (VII). The effect of butadiene/isoprene mass ratio in HSIBR on the performance of VII for lubricants was investigated here for the first time. HSIBR used as VII for lubricants integrated some advantages of hydrogenated styrene-butadiene rubber and hydrogenated styrene-isoprene rubber. Copyright © 2014 John Wiley & Sons, Ltd.

ABSTRACT Random styrene-isoprene-butadiene rubber (SIBR) were achieved with the catalyst system composed of neodymium isopropoxide (Nd(OiPr)3), methylaluminoxane (MAO) and indene. This catalyst proved to be highly effective in cyclohexane even at low [Al]/[Nd] ratio (ca. 50) to give styrene-rich terpolymer with high number-average molecular weight ( Mn) and narrow molecular weight distribution ( Mw/ Mn). Indene was critical to improve the coordination of styrene. High temperature was beneficial to increase the yield. Aliphatic solvents (hexane and cyclohexane) achieved a higher Mn of polymer than toluene as a solvent. The glass transition temperature ( Tg) and composition of SIBR can be controlled by tuning the feed ratio of monomers. All the products have been fully characterized by NMR spectroscopy, gel permeation chromatograph (GPC), and DSC. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

• The crack of SIBR grows slower, but is deeper. The number of the cracks is smaller. • SIBR has a strong resistance to ozone cracks, which can be used for tire tread. • SIBR mainly participate in the ozone aging reaction where concentrated on the cracks. • The cis-1,4-polybutadiene unit in SIBR and SSBR is more prone to take ozone aging. • Nd-IR has poor ozone aging resistance due to lots of carbonyl structure produced. The evolution of the structure, cracks and mechanical properties of Styrene-Isoprene-Butadiene Rubber (SIBR) during ozone aging process is investigated in this work. SIBR is a new type of tire tread rubber, and ozone aging is a key factor affecting the service life of tires. Therefore, it is very important to study the ozone aging performance of SIBR. The changes in the microstructure of the rubber at the ozone crack are innovatively monitored by the microscope-infrared technology in this work. The rubber is more prone to undergo ozone aging at the ozone crack. SIBR mainly participates in the ozone aging reaction where concentrated on the cracks. Therefore, the number of cracks on the surface of SIBR is relatively smaller. In comparison with Solution polymerization Styrene Butadiene Rubber and Neodymium Catalyzed-Isoprene Rubber (Nd-IR), the initial cracking time of SIBR is in the middle of the initial cracking time of SSBR and Nd-IR, and the growth rate of ozone cracks in SIBR is slower. In summary, SIBR has better resistance to ozone cracking. [ABSTRACT FROM AUTHOR]

The effect of amine antioxidant D37 on the structure and performance of Styrene-Butadiene-Isoprene rubber (SIBR) during ozone aging process has been studied in this work, and simultaneously compared with Styrene-Butadiene rubber of Solution polymerization (SSBR) and Neodymium Catalyzed-Isoprene Rubber (Nd-IR). It can be seen from the ATR-FTIR spectrum that the introduction of antioxidant D37 has a better protective effect on polyisoprene structural units, and the protective effect of antioxidant D37 on SIBR is in the middle of those of on SSBR and Nd-IR. From the results of microscope-infrared, after adding antioxidant, the intensity of the absorption peak of carbon-oxygen bond structure is obviously weaker than that without antioxidant, but is stronger than that of the sample surface. It is attributed to the diffusion and migration of the antioxidant from the inside of the sample to the surface of the sample, preventing the ozone from reacting with the rubber, and effectively preventing the generation and expansion of ozone cracks. After adding antioxidants, the initial ozone cracking time of SIBR is prolonged, and the initial ozone cracking time is in the middle of the initial ozone cracking time of SSBR and Nd-IR. The introduction of carbon black inhibits the protective effect of antioxidant D37, shortens the time of initial ozone cracking, and obviously increases the length and depth of the cracks, but the number of cracks decreases, resulting in a greater decrease in the mechanical properties of SIBR after ozone aging. [Display omitted] • The introduction of amine antioxidant has a better protective effect on polyisoprene structural units. • The protective effect of amine antioxidant on SIBR is between SSBR and Nd-IR. • The diffusion of the antioxidant in SIBR, effectively preventing the generation and expansion of ozone cracks.

• The conjugated carbonyl group is generated in SIBR during the aging process and since SIBR contains both cis 1,4-polyisoprene and 3,4-polyisoprene units. • Due to the larger side groups in the 3,4-polyisoprene unit, it needs a higher temperature in the aging process to generate the conjugated carbonyl group. • The thermal-oxidative aging of SIBR performed the cross-linking reaction and chain scission reaction generated simultaneously in the aging process, but the cross-linking reaction is dominated. The thermal-oxidative aging of Styrene-Isoprene-Butadiene Rubber (SIBR) has been studied using transmission spectroscopy in In-situ. These In-situ FTIR imaging results have interpreted the microstructure and mechanism of SIBR in the thermal-oxidative aging process. The conjugated carbonyl group is generated in SIBR during the aging process because SIBR contains both cis 1,4-polyisoprene and 3,4-polyisoprene units. The generation rate of the conjugated carbonyl group in SIBR is significantly increased with the prolonged aging time. Moreover, due to the larger side groups in the 3,4-polyisoprene unit, it needs a higher temperature in the aging process to generate the conjugated carbonyl group. Based on the changes of methylene and -C-O bond during the aging process, the thermal-oxidative aging of SIBR has been found that the cross-linking reaction and chain scission reaction take place simultaneously, but the cross-linking reaction dominates the degradation. Compared with Solution-polymerizated-Styrene-Butadiene Rubber (SSBR) and Nd-Polyisoprene Rubber (Nd-IR), the thermal-oxidative aging rate of SIBR is between SSBR and Nd-IR in view of the changes in carbonyl group and –C O structure during the aging process.
