Synthesis of several bisabolane sesquiterpenoids from xanthorrhizol isolated from C. Xanthorrhiza [PDF]

, 2005
Xanthorrhizol was isolated from the essential oil of fresh rhizomes of C. xanthorrhiza in 20.2% yield by fractionation using vacuum liquid chromatography. Several bisabolane-type sesquiterpenoids have been synthesised from this xanthorrhizol.

Sudan at War With Itself: Civilian Devastation in the Civil War

Conflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Resilience Practices and Post‐Traumatic Growth Among Sudanese IDPs

Conflict Resolution Quarterly, EarlyView.
ABSTRACT In this paper we examine the resilience of internally displaced persons (IDPs) in Sudan who have endured various forms of suffering resulting from being targeted or trapped by militants involved in large‐scale violence. Upon escaping the conflict zones, the civilians exhibit strength, adaptability, and wisdom in the face of various threats to ...

Optimization of hop essential oil extraction by means of supercritical CO2

Biologija, 2011
Supercritical fluid extraction (SFE) can reduce sample preparation time and the recovery can be equal or better than that of the classical extraction techniques for solid and semi-solid samples. Extraction efficiency and speed can benefit from specific properties of a supercritical fluid.

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.

Dynamics of Isomerization of Hop Alpha-Acids and Transition of Hop Essential Oil Components in Beer.

Acta chimica Slovenica, 2021
Hops' unique composition of essential oil components and bitter resins are crucial for beer aroma, which is important to consumers' acceptance of beer. In this experiment the same wort was divided into four portions and each was hopped differently. To determine the dynamics of isomerization rates the concentrations of alpha- and iso-alpha-acids were ...

A Three‐Dimensional Structural Model for Predicting Magnetic Exchange and Hydrogen Positions in Bis‐μ‐Hydroxido Cu(II) Dimers

European Journal of Inorganic Chemistry, EarlyView.
Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.
