this study examined the effects of trade liberalization and exchange rate changes on carbohydrate staples in nigeria. secondary data published from 1974 to 2006 on cassava exports and rice imports as well as non-tradable carbohydrate staples were used. it was hypothesized that exchange rate changes and trade liberalization via price relatives, trade intensity and nominal protection coefficient ...

The onslaught of COVID 19 forced the closures schools, but upon their gradual reopening need for high quality substitute school teachers was at an all-time high. Although many districts were in well before pandemic struck, this disease illuminated fact that across nation short supply. In economic environment where other jobs may offer higher pay, more benefits, less stress, and professional res...

Purpose. Impaction fractures of the anterior aspect of the humeral head, the reversed Hill-Sachs lesion, are common in posterior shoulder dislocation. We present a new technique to address these lesions arthroscopic-assisted with the use of a bone substitute. Methods. We report the case of a 45-year-old male with a reversed Hill-Sachs lesion after posterior shoulder dislocation. Initially a gle...

It was previously reported from this laboratory that the secondary antibody response can regularly be elicited in vitro from fragments of rabbit lymph node node cultured in Eagle's medium supplemented with normal rabbit serum. Evidence is now presented that physiological levels of hydrocortisone (0.01 to 1.0 microM) can substitute for serum in the culture medium. However, with the omission of s...

Let $R$ be a commutative ring with identity and let $M$ be an $R$-module. In this paper, we will introduce the secondary radical of a submodule $N$ of $M$ as the sum of all secondary submodules of $M$ contained in $N$, denoted by $sec^*(N)$, and explore the related properties. We will show that this class of modules contains the family of second radicals properly and can be regarded as a dual o...

In order to analyze the operation of the protection system during induced fault testing in the Croatian power system, a simulation using the CAPE software has been performed. The CAPE software (Computer-Aided Protection Engineering) is expert software intended primarily for relay protection engineers, which calculates current and voltage values during faults in the power system, so that relay p...
