In the title compound, C(46)H(80)O(3), a natural ursane-type triperpenoid, four of the five six-membered rings adopt chair conformations; the fifth, which has a C=C double bond, adopts an approximate half-boat conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming chains along [010].

The purpose of this study was to evaluate the Outcomes Assessment Information Set (OASIS) compared with the Probability of Readmission (P(ra)) instrument for use in predicting rehospitalization during home care. Using logistic regression and receiver operating characteristic (ROC) curve analysis, the P(ra) instrument was found to be significantly better at predicting rehospitalization than the ...

Abstract Climate change is a complex and multi-layer issue with global local entanglement. In this study, Langat River Basin chosen. Secondary data was used including the historical flood drought event reports, Standardized Precipitation Index-1 Canadian Earth System Model (CanESM2) along Australian Community Simulator Coupled (ACCESS CM-2). These were to determine monthly precipitation risk ba...

Water is an essential resource for social and economic development. The availability of this constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- (2017–2040), middle- (2041–2070), long-term (2071–2099) levels water security considering socio-economic climate change scenarios using Evaluation Planning System (WEAP) Vilcanota-Urubamba (VUB)...

We formulate an optimal stopping problem where the probability scale is distorted by a general nonlinear function. The problem is inherently time inconsistent due to the Choquet integration involved. We develop a new approach, based on a reformulation of the problem where one optimally chooses the probability distribution or quantile function of the stopped state. An optimal stopping time can t...

survival in patients with HCC in two independent cohorts, and the mechanism was associated with low VEGFR-1 expression levels in HCC. Grant support: This research was supported by grants from the National Scientific Council (NSC 100-2314-B-075-051, NSC 101-2321-B075-004) and Taipei Veterans General Hospital (V101B-005, V102E2005 and V102E2-006) to YF Hu, (NSC99-3112-B-010-005-CC1, NSC1002627-B-...

many environmental and physiological factors affect plant temperature. the objective of this study was to use thermal imagery to investigate robust features for early diagnosis of botrytis cinerea infection in cut rose flowers under the postharvest application of methyl jasmonate (meja). three cases treated with different concentrations of meja (0.1, 0.2, and 0.3 µl.l−1), a control (0 µl.l−1 me...

In the title compound, C14H10ClNO2, obtained by the condensation of 4-chloro-aniline and piperonal, the five-membered ring is almost planar (r.m.s. deviation = 0.023 Å) and the dihedral angle between the aromatic rings is 43.22 (14)°. In the crystal, a short O⋯Cl contact of 3.173 (2) Å is observed. The mol-ecules are arranged into corrugated (010) layers.

In the title compound, C(15)H(17)NO(8), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 6.4 (3) Å]. The five-membered ring has a twist conformation. In the crystal, C-H⋯O inter-actions link the mol-ecules into a helical chain propagating along [010].

In the title mol-ecule, C(12)H(18)Cl(2)N(2)O(2), the six-membered ring is in a chair conformation and the five-membered ring is in an envelope conformation. In the crystal, weak inter-molecular bifurcated (C-H)(2)⋯O hydrogen bonds connect mol-ecules into chains along [010].
