A telescopic platform is equipment used
in the Laboratory or Workshop to carry out different kinds of job on the
ceiling e.g. fixing or replacing of electric bulbs, fixing of electric fans
etc. it is also used to change streetlight on campus. Now that technology
changes rapidly, the use of step ladders of different kinds with low
reliability and quite a number of limitations should gradually be replaced by
less expensive alternati ...

Background: There is limited scientific evidence supporting the efficacy of aphrodisiacs and more worrying is the fact that potential adverse health effects could result from the abuse of aphrodisiacs. Despite the safety concerns raised by the FDA on the abuse of unregistered sex enhancing products, the patronage remains high amidst debilitating side effects. We explore the factors influencing the use of aphrodisiacs while assessi ...

In this paper we present our views on algebra as a school subject. To say pre-cisely what is the content of this subject, the language of abstract algebra has to be used. Accordingly, this content consists of the establishing and application of the properties of operations in the system of natural numbers which are then carried over to the extended systems. In the last of these extensions—the set of rational numbers, these propert ...

In view of the incompleteness of the methods used in the location selection of today’s shared car charging stations, the author proposes to combine the two methods of AHP and fuzzy evaluation to construct an evaluation index system and a fuzzy level evaluation model. The two alternative electric vehicle charging station addresses are comprehensively evaluated to achieve the most preferred address. Pr ...

Background: We sought the value of the six-minute walk test distance in predicting re-admission in patients with chronic heart failure (CHF) in the department of cardiology, Yalgado Ouédraogo University Hospital, Ouaga-dougou, Burkina Faso. Methods: We did a prospective observational study in patients hospitalized with acute decompensated heart failure and who underwent a 6-minute walk test (6-MWT) at their discharge from hospital ...

Introduction: Mucinous carcinoma of the breast constitutes 1% to 4% of all breast cancers. Two different forms of
presentation are distinguished: pure mucinous carcinoma and mixed mucinous carcinoma. The purpose of our work was to clarify the anatomo-clinical and radiological particularities of this rare form of breast cancer. Materials and
methods: This was a retrospective study of a series of 14 cases of mucinous carcinoma of th ...

By using the gravity equation for quantum mechanical
systems that takes into account the non-local interaction of the quantum
potential the paper derives the quantization of the graviton in the limit of
weak gravity. The output of the theory shows that, in the non-Minkowskian
quantum approach proposed, where the coupling between the gravitational
equation and the field is explicitly defined, a massless boson fie ...

In the new era, the construction of ecological
civilization in China has been raised to a new strategic height, which puts
forward stricter requirements and provides new impetus for enterprises to
fulfill their environmental responsibilities. At present, there are still many
problems when Chinese enterprises fulfill their environmental responsibilities.
From the perspective of Xi Jinping’s thought of ecological civilization, t ...

In the mathematical model of electrostatic sensors established by Yan Yong in previous studies, the thickness of the insulating layer was not taken into account in the model. In order to study the static monitoring of electrostatic sensors in more depth, this paper considers the influence of insulation layer when establishing the mathematical model of the sensor. By establishing a mathematical ...

Objectives: The primary objective was to determine if the current pre-season screen used by the Nashville Ballet was identifying dancers at risk for injury and determining the injury rates and patterns of injury within the company. The secondary purpose of this study is to propose more objective measurement tools to enhance the pre-season screen. Background: Professional ballet dancers are at an increased risk for lower extremity ...
