writing as a productive skill requires practice in the basic sub-skills of vocabulary and grammar. in fact, grammar has been viewed as the core of programs in writing classes to help the students put the elements of sentence together and combine sentences of specific lengths to come up with an error-free work of art. conceptualizing l2 writing in this way introduces writing as a product and enc...
OBJECTIVE Early assessment of response to neoadjuvant chemotherapy (NAC) for breast cancer allows therapy to be individualized. The optimal assessment method has not been established. We investigated the accuracy of automated breast ultrasound (ABUS) to predict pathological outcomes after NAC. METHODS A total of 290 breast cancer patients were eligible for this study. Tumor response after 2 c...
This paper proposes a novel deterministic optimization approach for the Unit Commitment (UC) problem, involving thermal generating units. A mathematical programming model is first presented, which includes all the basic constraints and a set of binary variables for the on/off status of each generator at each time period, leading to a convex mixed-integer quadratic programming (MIQP) formulation...
In the title mol-ecule, C(10)H(13)NO(2), the amide -NH(2) group is oriented toward the prop-oxy substituent and an intra-molecular N-H⋯O hydrogen bond is formed between the N-H group and the prop-oxy O atom. The benzene ring forms dihedral angles of 12.41 (2) and 3.26 (2)° with the amide and prop-oxy group mean planes, respectively. In the crystal, N-H⋯O hydrogen bonds order pairs of mol-ecules...
