Physiochemical Study of Extract of African Marigold as A Source of a New Acid Base Indicator

Introduction

Physiochemical Studies

            The physiochemical studies of substances include identification or characterization of substances based on their physical and chemical properties. According to Keren (2003), “A physical property is any property of an object or substance that can be measured or perceived without changing its chemical identity”. The physical properties an object might have include absorption, boiling point, colour, density, distribution, frequency, length, mass, melting point, strength, temperature, volume etc (Keren, 2003).

John   and Paul (1996) defined chemical property as properties of a substance that become evident during chemical reaction; that is any quality that can be established only by changing a substance chemical identity. Examples include pH, electrogengativity, heat of combustion, enthalphy of formation, toxicity, flammability, chemical stability in a given environment, coordination number etc (John   and Paul 1996).

Effect Of Alcoholism and Suggest Ways It Could Be Prevented

Effect Of Alcoholism and Suggest Ways It Could Be Prevented

Introduction

Background of the study

          Despite well known risks, people continue to depend on alcohol, and such continue to destroy lives. Alcoholism is a compulsive use of a substance or alcohol, despite its negative and dangerous effect to the individual, family, and the society at large. The problem of alcoholism among young men has worried many governments and institutions all over the world this problem is not a new thing man is known to be a social animal that has been using drugs right from the early life.

Factors Militating Against the Use of Observation in Rendering Effective Nursing Care Among Undergraduate Students

  Factors Militating Against the Use of Observation in Rendering Effective Nursing Care Among Undergraduate Students

Observation of the patient is one of the nurses most important, though unobtrusive duties. The development of the power of observation is an essential part of the nursing training.

According to Wehmeier and Sally (2008) observation is the faculty of taking notice. The ability to do this well depends on training and experience and is of particular importance in nursing.

The medical staff is, to a very great extent, dependent on the observations made by the nurse, as the nurse spends a great deal of her time at the bedside with the patients (Usman, Obajemihin, and Adegbite 2011). [Read more…]

Sensory Properties of Zobo

Sensory Properties of Zobo

The name “Zobo” is derived from the local Hausa (Northern Nigeria) name for the Rosella plant is, “Zobrodo”.It is quite popular in Northern Nigeria enjoying patronage at various social gatherings and its popularity has recently spread across the entire country because of its purported medicinal value as well as the increasing cost of other available soft drinks whose concentrates mostly constitute a drain on the economy in spite of the increasing popularity of “Zobo” juice of its greatest limitation for large scale production is that deteriorates rapidly. In fact, its half life is approximately 24hours following production if not refrigerated.

Studies On Corrosion Of Aluminum In Hydro Chloric Acid Containing Siam Weed Extract

Studies On Corrosion Of Aluminum In Hydro Chloric Acid Containing Siam Weed Extract

Corrosion is a core problem that must not be ignored but rather confronted for safety, mechanical, environmental, and economical reasons in various chemical, metallurgical, biochemical and medical engineering applications and more specifically in the design of a much more varied number of mechanical parts which equally vary in size, in function and in useful life span.

In order to reduce the corrosion of metals, several techniques have been applied. The use of inhibitors during acid pickling procedure is one of the most practical methods for protection against corrosion in acidic media. [Read more…]

Computer Networking and Components

Student industrial work experience scheme (SIWES) On Computer Networking and Components

 

Student industrial work experience scheme (SIWES) is the scheme organised by national university commission (UNC) in conjunction with Industrial Training Fund (ITF) and also funded by Federal Government of Nigeria (FGN) in the institution of higher learning. This is a skill acquisition programme which was designed and implemented for the tertiary to the theoretical education and laboratory practices. SIWES aims at exposing students to the industrial machine, equipment use, professional working method and ways of safe guarding industries.

Therefore, the schemes mould the student to confirm easily to the job specification profession they are likely to meet after graduation. Conclusively, it has made merit contribution in full training of student in various disciplines. [Read more…]

Comparison of Rabbit Brain Phospholipid Extract Activity With That of Commercial Extract

 Rabbit Brain Phospholipid Extract Activity With That of Commercial Extract

Phospholipids are a group of lipid containing a phosphate group as part of the molecule. Phospholipids are constituents of all tissues and organs, especially the brain. They are synthesized in the liver and small intestine and are involved in many of the body’s metabolic processes. (Elizabeth and Martin,2002).

Phospholipid often occur with other molecules e.g. proteins, glycolipids and cholesterol in a bilayer such as cell membrane. (Campbell et al, 2006). There are many types of phospholipids e.g. Phosphatidylcholine (Lecithin), phosphatidylethanolamine (Cephalin), phosphatidylserine, phosphoinosides and plasmalogens, each with different function in the body. E.g. cephalin in the activation of intrinsic pathway of coagulation system in the presence of calcium. Cephalin is found particularly in nervous tissue, such as white matter of brain, nerves, neural tissue and in spinal cord. [Read more…]
