Threshold Effects of Public Spending on Sectoral Growth in Sub-Saharan Africa

Prudence M. Kotounnou, François Joseph Cabral

World Scientific News > 2023 > 176 > 145-161

This paper analyzes the effects of public expenditure thresholds on the sectoral contribution to GDP growth with particular emphasis on the three macro-sectors of the economy (agriculture, industries and services). It appears that when public expenditure in the "agriculture" sector is less than 1.22% of national GDP, it has an insignificant and negative effect on the contribution of this...

Reformulating and Strengthening the Theoretical Foundations of Semi-structured Complex Numbers

Jean-Paul Peter, Wahid Shanaz

World Scientific News > 2022 > 169 > 152-182

Recently a new number p (called the unit unstructured number) was invented to solve “division by zero”. “p” was used to create a new number set called the semi-structured complex numbers and a new coordinate plane called the real-unstructured xz-plane. However, the definition of p led to a number set that had a poor theoretical foundation and lacked consistency in simple algebraic calculations producing...

Current trends in the treatment of sickle cell anemia

Waheed Sakariyau Adio, Francisca Chioma Christopher, Ridwan Olamilekan Adesola, Folorunso Ibikun Mary

World News of Natural Sciences > 2022 > 43 > 60-75

Sickle cell disease is a set of illnesses characterized by the misshaping and breakdown of red blood cells. Red blood cells twist into a sickle shape in sickle cell disease, an inherited set of illnesses. The cells die early, resulting in a lack of healthy red blood cells (sickle cell anemia), and they might impede blood flow, causing pain (sickle cell crisis). Vernon Mason coined the term "sickle...

Water quality index based on interrelation between plankton and benthos in Cimanuk River, Majalengka District, West Java, Indonesia

Achmad Rizal, Izza M. Apriliani, Lantun P. Dewanti

World Scientific News > 2022 > 168 > 81-98

Water quality can be known from the value of WQI (Water Quality Index), a number that describes water quality based on measurements of water quality parameters. Plankton is an organism whose life is free to hover in the water, its ability to move is limited so that water currents easily carry it away. Benthos is an organism that lives on the seabed or river attached to water sediments (mud or sand)...
