The purpose of the current paper is to propose a new model for the secondary goal in DEA by introducing secondary objective function. The proposed new model minimizes the average of the absolute deviations of data points from their median. Similar problem is studied in a related model by Liang et al. (2008), which minimizes the average of the absolute deviations of data points from their mean. ...

In this paper, a study has been carried out to analyze the factors influencing the current transformer (CT) saturation factor (KS), in particular the secondary time constant (TS) of a CT. The study identifies and analyzes the optimum value for TS as this value varies. This paper also analyses and discusses the effect of TS to the KS factor in order to calculate the CT knee point voltage (VK) in...

Higher plants are an important source of secondary metabolites such as flavours, fragrances, dyes, pigments, food additives, terpenoids, alkaloids, and glycosides with medicinal importance. Several of these secondary plant products also form the basis for drug development. Today, several countries use plant derived chemicals as drugs with modifications. Unfortunately, these secondary plant prod...

A technique based on the analytical method of lines is presented for predicting shape changes during electrodeposition. The technique is presented for both primary and secondary current distributions. The method presented does not require iterations for nonlinear Butler-Volmer boundary conditions or changing electrode shapes. The technique is based on a semianalytical method developed earlier f...

Hyperparathyroidism (HPT) is a common complication in haemodialysis patients, associated with morbidity and sometimes mortality [1]. In the majority of patients with secondary hyperparathyroidism (2HPT), this can be managed by medical treatment but this does not always give adequate control of the parathyroid disorder. Some patients require intervention treatment of the parathyroid glands inclu...

Ovarian hyperstimulation syndrome (OHSS) is still a severe complication due to controlled ovarian stimulation for artificial reproductive technology. Even though multiple techniques to avoid OHSS have been discussed in the last decades, up to now no clear concepts for primary and secondary prevention exist. This review gives an overview over proposed strategies to avoid OHSS. In a retrospective...

This paper examines the domain of digital reference services for and by the primary and secondary education community. Data is provided to demonstrate the current understanding of education question types and education users in digital reference. It is believed this data will be of wide utility for digital library builders geared toward primary and secondary users (K-12) such as the Internation...

Spontaneous pneumothorax can be either primary due to the rupture of subpleural bleb or secondary due to underlying lung disease, usually bullous emphysema.1 Relatively little is known about the causative factors of spontaneous pneumothorax in Arab Countries.1 This is the first study and the primary step towards understanding the risk factors and causes of spontaneous pneumothorax in Syria.Syri...

The opercular somatosensory region (OP) plays an indispensable role in pain perception. In the present study, we investigated the neurophysiological effects of transcranial direct current stimulation (tDCS) over the OP. Somatosensory-evoked magnetic fields following noxious intraepidermal electrical stimulation to the left index finger (pain-SEFs) were recorded before and after tDCS with a sing...
