Effect of Refinery on Spearmint (Mentha spicata var. Viridis l) Oil Quality

Spearmint (Mentha spicata var. Viridis) plants were raised from underground runners obtained from fully mature plants. Eighty milligrams of spearmint oil were distilled in 200 ml of distilled water. Oil was extracted by water distillation according to the technique of British Pharmacopoeia. Physico-chemical properties including, relative density, optical rotation, refractive index, acid value and ester value were determined according to British Standards Institute. The process was repeated to give the first, second and third refined levels. Relative density, optical rotation and refractive index of spearmint oil significantly decreased with progress in the refining process. Acid values showed a decrease trend from 0.8475 in the crude oil to 0.5610, 0.4210 and 0.3740 in the first, second and third refined oils, respectively. ...

Appraisal of timing for oral glucose tolerance testing in relation to risk factors for gestational diabetes mellitus in pregnant women in a Nigerian Teaching Hospital

Nigerian journal of clinical practice, 2015

OBJECTIVE We investigated the pattern of common risk factors present in women undergoing oral glu... more OBJECTIVE We investigated the pattern of common risk factors present in women undergoing oral glucose tolerance test (OGTT) in our center and to determine their relationship with time of presentation for the test. MATERIALS AND METHODS The records of women referred to the metabolic clinic for OGTT over a 1-year period were reviewed. Data available for retrieval included age, gravidity and gestational age, weight, and risk factors for gestational diabetes mellitus (GDM). RESULTS Two hundred and fifty-three (253) pregnant women form the subject of this study. Thirty-five (13.8%) of the study population had GDM by WHO criteria. Approximately, 10% of the women were tested before 24 weeks and 87.6% of the women had at least one of the common risk factors as indication for testing. The most frequent indications were a history of previous macrosomic baby 77 (30.4%) and maternal obesity 61 (24.1%). Among the indications for OGTT, only a history of previous intrauterine fetal death was signi...

New adaptive blind equalizer for FIR channels with non-zero delay dominant tap

2004 23rd IEEE Convention of Electrical and Electronics Engineers in Israel, 2004

The algorithm is based on a novel demonstration of a system and observation state space equations, and estimates the transmitted data without any a-priori knowledge on the channel response. Traditional solutions for the problem of equalization, that make use of state space model solutions, do not include the discrete low pass filter (LPF) that exists, in many communication systems, in order to limit the bandwidth of the transmitted symbols. These solutions cannot perform well when the channel has a dominant tap (or more than one) with non-zero delay. Our method shows robustness to different channels, and especially to channels with a non-zero delay dominant tap.

Effect of Moringa (Moringa oleifera) leaf powder and sweet basil (Ocimum basilicum) leaf paste on sensory and nutritional qualities of beef and ham burgers - A preliminary study

This study was conducted to determine the effects of Moringa ( Moringa oleifera ) leaf powder (MLP) and Sweet basil ( Ocimum basilicum ) leaf paste (SBLP) on the sensory characteristics and nutritional compositions of beef and hamburgers. MLP and SBLP were incorporated at 0g (Control, T1), 2g, 4g and 6g/kg meat (T2, T3 and T4 respectively) during the production of the burgers. The burgers were vacuum-packed and frozen for sensory and laboratory analyses. The M. oleifera leaf powder had significant (P 0.01) the crude protein content but no significant effect on sensory characteristics of the products.

The experiment involved the use of basil leaves powder at 4, 6 and 8g/kg meat in place of adobo®, a commercially formulated spice in both beef and frankfurter sausages. Sensory attributes such as colour, aroma, flavour intensity, flavour liking and texture were evaluated. The addition of basil leaves powder resulted in a significant (P<0.001) effect on the colour of both beef and frankfurter sausages. The control and 4g of the test materials in beef and frankfurter sausages had acceptable sensory attributes as compared to the higher levels (6 and 8g/kg). Sweet basil leaf powder did not have any adverse effect on the sensory characteristics of the products. There was significant difference (P<0.05) among treatment means in terms of fat content of the frankfurter sausages. However, the moisture and crude protein content of bo...
