Chelated minerals for poultry
Vieira, SL;
Revista Brasileira de Ciência Avícola , 2008, DOI: 10.1590/S1516-635X2008000200001
Abstract: organic minerals have been subject of an increasing number of investigations recently. these compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never required a lot of attention in terms of quality. on the other hand, definitions of organic minerals are very broad and frequently lead to confusion when decision-making becomes necessary. organic minerals include any mineral bound to organic compounds, regardless of the type of existing bond between mineral and organic molecules. proteins and carbohydrates are the most frequent candidates in organic mineral combinations. organic fraction size and bond type are not limitations in organic mineral definition; however, essential metals (cu, fe, zn, and mn) can form coordinated bonds, which are stable in intestinal lumen. metals bound to organic ligands by coordinated bonds can dissociate within animal metabolism whereas real covalent bonds cannot. chelated minerals are molecules that have a metal bound to an organic ligand through coordinated bonds; but many organic minerals are not chelates or are not even bound through coordinated bonds. utilization of organic minerals is largely dependent on the ligand; therefore, amino acids and other small molecules with facilitated access to the enterocyte are supposed to be better utilized by animals. organic minerals with ligands presenting long chains may require digestion prior to absorption. after absorption, organic minerals may present physiological effects, which improve specific metabolic responses, such as the immune response. many studies have demonstrated the benefits of metal-amino acid chelates on animal metabolism, but the detection positive effects on live performance is less consistent.
Evaluation for the retention of reproductive structures by Bt and non-Bt intra hirsutum cotton hybrids in different sowing dates and spacings
SL Ahuja
African Journal of Biotechnology , 2006,
Abstract: The retention of the reproductive structures (bolls) was evaluated at 90,120 and 160 days of maturity in eight Bt and non-Bt hybrids from three Private R&D establishments on three dates of sowings (90,120 and 160 days of maturity) and two spacings of 67.5 x 60 cm and 100 x 30 cm. Ankur group Bt hybrids; 651, 2226 and 2534 had reproductive structures retentivity higher than their non-Bt counterpart hybrids in all the three sowings and spacings. However, RCH group Bt hybrids; 134 and 138 had lesser/comparable boll retentivity in first two observations at 90 and 120 days in the earliest and the next sowing. In the last sowing with wider inter row spacing their trend was similar to Ankur group hybrids in the first sowing. MRC 6301 also behaved like RCH group hybrids. Bt hybrids of all the three establishments had more reproductive structure retentivity than their non-Bt hybrids counterparts in early, closer inter row and wider intra row sowing except for Bt hybrid RCH134 which had the highest bearing in the late sowing with wider inter row and closer intra row spacing. Association study indicated similar trend of boll bearing in Bt and non-Bt hybrids in early sowing and this trend seems to be reverse in later sowings
Applying lean Six Sigma to reduce linen loss in an acute care hospital
SL Furterer
International Journal of Engineering, Science and Technology , 2011,
Abstract: This paper describes a case study in an acute care hospital that formed a cross-functional team to apply the Lean Six Sigma problem solving methodology and tools to improve the linen processes. The goal of the project was to identify and implement process improvements that would reduce linen loss. The project team applied the Six Sigma DMAIC (Define-Measure-Analyze-Improve-Control) problem solving approach. The team was able to improve the key linen operational metric, soil to clean linen ratio by 16% and saved $77,480 for the first year, by making operational improvements and implementing automated linen and scrub dispensers.
Ethnopharmacological and Phytochemical Review of Allium Species (Sweet Garlic) and Tulbaghia Species (Wild Garlic) from Southern Africa
SL Lyantagaye
Tanzania Journal of Science , 2011,
Abstract: Tulbaghia (wild Garlic) is a plant genus most closely related to the genus Allium both in the family Alliaceae and is entirely indigenous to Southern Africa. Indigenous people use several species of the genus as food and medicine, and few species are commonly grown as ornamentals. Biological and pharmacological research on Tulbaghia species and their relationship with Allium sativum (sweet Garlic) are presented and critically evaluated. Informations from studies on the treatment of microbes-caused diseases as well as of cancer have been presented in ethnobotanical reports. Moreover, recent scientific studies have been performed on crude extracts for certain Tulbaghia species as reviewed in this article. This article gives a critical assessment of the literature to date and aims to show that the pharmaceutical potential of the members of the genus Tulbaghia is comparable to that of its close relative A. sativum but has been underestimated and deserves closer attention.

Unnecessary & Unsafe Injections Replace Disposable by Auto-Disable Syringes
SL Srivastav
Journal of Universal College of Medical Sciences , 2013, DOI: 10.3126/jucms.v1i3.8770
Abstract: Injections are a skin procedure performed with a syringe and needle to introduce a substance for prophylactic, curative, or recreational purpose. Injections can be given intevenously, intramuscularly, intradermally, or subcutaneously. Injections are among the most frequently used medical procedures, with an estimated 12 billion injections administered worldwide. ?A large majority (more than 90%) of these injections are administered for curative purpose (for every vaccination, 20 curative injections are administered).
Nutri??o Pós-Eclos?o de Frangos de Corte
Vieira, SL;Pophal, S;
Revista Brasileira de Ciência Avícola , 2000, DOI: 10.1590/S1516-635X2000000300001
Abstract: the emergence from the shell delineates the end of a period of incubation with extremes between 480 to 510 hours after the chicken lays the egg. precocial birds hatch with a yolk sac attached containing residual albumen and yolk. these reserves are very important in the first hours after hatching while the birds adapt to the independent feeding with resources originating from the external environment. apparently, the post-hatched bird does not have important restrictions to utilize nutrients obtained externally. one possible exception is the reduced ability for fat emulsification due to lower availability o bile salts. however, placing the birds as soon as they hatch accelerates adaptation to the independent life that leads to improved performance. delaying bird placement in the house reduces the overall potential for protein deposition, especially in the breast muscle. traditional broiler feeding programs use one feed from hatching to 3 weeks. there is an increasing interest for a diet elaborated to compensates for the uniqueness of the first days of birds lives. differences in nutrient requirements between the post-hatching chick and more mature birds seem to be obvious. however, the information available on this subject is scarce which makes the proposed commercial pre-starter diets be very conflicting.
The Impact of Forecasting on Strategic Planning and Decision Making: An Exploratory Study of Nigerian Stock Exchange
SL Adeyemi, MA Aremu
African Research Review , 2009,
Abstract: Ineffective application of effective planning in many organisations is the main thrust for their inability to predict and make a sound decision which lead to the failure to achieve projected performance. This paper examines the decision making and planning process with the use of multiple regression analysis model to forecast the stock market activities of each sector listed on Nigerian stock Exchange by using the number of deals in share and number of share in unit to explain the strength of relationship and the extend of relationship between the value of share in Naira i.e. capitalization in stock for every listed trading sector on Nigerian Stock Exchange market. This study was designed to give strategic managers practical suggestions for better understanding of the forecast so that managers can plan their reactions effectively to enable better performance. The prime objectives of this paper is to develop an operational research model that will assist investor, investment manager and stock broker that participate in stock exchange trading to have an accurate forecast of trading activities on Nigeria stock market. Also, to determine the most suitable planning strategies for the investment manager in relations to Nigeria stock market activities. A dynamic regression model was used as an input data to analyse part of this empirical study that consist of activity summary of Nigerian Stock Exchange. The paper suggestion was based on the recognition that forecasts are derived to serve specific strategic planning and decision making, and that these decisions must be congruent with the company strategy. It therefore concludes that future forecasting must be based on several factors that can affect market value which call for the broadening the understanding of the role of forecasts in strategic decision making.

SL Mengistu, AE Shimelis
African Journal of Food, Agriculture, Nutrition and Development , 2012,
Abstract: Dextrose was produced from locally available hybrid variety of maize (Bako Hybrid-660) in Ethiopia, using acid extraction. The variety was selected as an experimental input from Bako Agricultural Research Centre for the production of intermediate product starch using wet milling and end-product dextrose. The proximate composition values in the wet, milled, dried and cleaned white dent 2000 g BH-660 maize when steeped in 0.3% sulfur dioxide for 46 hrs at 50oC were determined. The mean values were 11.74%, 64.15%, 4.51%, 10.23%, 6.53% and 2.81%, for moisture content, total starch, germ, gluten, husk and fibre, respectively on dry weight basis. The total starch obtained from wet milling was 91.8% pure starch by mass. The proximate analysis values of moisture, crude protein, crude fat, crude fibre and total ash content of the sample were 7.65 %, 4.89%, 0.35%, 0.75 % 0.29 % , respectively on dry weight basis. Besides these, pH value was also determined to be 4.79. This obtained starch was hydrolyzed by an acid extraction method for the production of BH-660 maize dextrose. An average yield of 91.64% dextrose result was obtained and from this, 92.24% was pure dextrose by mass. Analysis result revealed that moisture, crude protein, crude fat, crude fibre and total ash content of the produced dextrose were 6.24%, 0.11%, 0.25%, 0.30% and 0.03%, respectively on dry weight basis. In addition, the pH value of 6.28 was determined. The control dextrose obtained from Ethiopian Pharmaceutical Manufacturing Share Company analysis values of moisture, crude fibre, crude fat and dextrose content were 5%, 0.24%, 0.23% and 93.73%, respectively on dry weight basis. From these data, it can be concluded that the BH-660 maize variety has a significant potential for the production of high quality starch and dextrose, which can be used as a raw material for starch and dextrose processing industries.
