The experiment was conducted at the Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, during the period from May 2012 to August 2012. Summer tomato seedlings were sprayed with four levels of maleic hydrazide viz. 0, 20, 40 and 60 ppm were arranged in Randomized Complete Block Design with three replications. Plant growth retardant- maleic hydrazide @ 60 ppm decrease plant height, increases number of leaves, branch, flowers (33%) and fruits (35%) plant -1 . It also increases individual fruit weight and yield of tomato ha -1 about 32% and 57%, respectively but it did not affect the fruit length and diameter.
An auspicious method for the quantitative determination of vitamin A (retinol) was augmented in seven different Jordanian local fresh milk samples using liquid chromatography tandem -mass spectrometry (LC/MS/MS). The compound was separated with C18 Thermo fisher gold (4.50 x100 mm x 5 Å) column through a flow rate of 1 mL/min with isocratic mobile phase. Vitamin A acetate was used as an internal standard .The method was validated using triplicate analyses, relative recovery experiment and statistical analysis. Liquidliquid extraction was employed as a pre-concentration step with n-hexane -dichloromethane mixture (90%:10%) as an extraction solvent. The concentration range of the working standards was 0.0-1000.0 ng/mL. The correlation coefficient was found to be 0.9994. The limit 0f detection and limit of quantification were found to be 0.53 and 1.78 respectively. The 95% confidence interval was calculated to be 49.032 + 0.22.
Patterns can be discerned within the changes. Patterns don’t predict the future, but help describe the change, and help the understanding of why, perhaps, and provide a baseline to measure current changes against. If nothing else, it’s an amusing thought experiment.
Some assignments will call for an abstract. An abstract is a summary of your paper. An abstract should be short and concise but include the topic of your paper, the main points you are writing about, and the conclusions you reach. Do not indent the 1st line of your Abstract It should be written in block format Include a brief sentence summary for all sections of your paper. An abstract is typically 150-250 words long. Your paper should: word Introduction as a heading. It is understood that the opening paragraph of your paper is your introduction. The APA suggests the following set up for an * be double spaced * have 1 inch margins introduction: Introduce the problem, explore the importance of the problem, describe relevant scholarship, and explain your approach to solving the problem. This may vary depending on your assignment. * be typed in Times font * indent paragraphs ½ inch or 5-7 spaces The Body of your Paper Headings should After you write the introduction, you will develop the body of the paper. be boldfaced, centered, and all major words In a formal psychology paper documenting an experiment, the standard capitalized structure for an experiment is: Method, Results, Discussion. Each of these Footnotes can be used to provide additional information sections would use a heading to guide the reader through the paper. The paper ends with References, Footnotes, Appendices and Supplemental Materials1. Consult the Publication Manual of the American Psychological Association
This study investigates the growth of three life stages of T. guineensis exposed to different sublethal concentrations of Parateq for 12 weeks in a static renewal bioassay. Parateq a synthetic based Fluid (SBF) was added to water to obtain the following sublethal concentrations 0.32%, 0.63%, 1.25 % and 2.5% vol/vol. Fry (0.64cm –0.65cm/0.52g – 0.55g) fingerlings (5.51cm–5.57cm/5.52g – 5.56g) and Post fingerlings (7.21 - 7.25cm / >10.5g) of T. guineensis were fed with NIOMR Feed. Proximate compositions of the feeds used were evaluated while the carcass composition of the fish was analyzed at the end of the experiment. Growth rates during the 12 weeks period were modest with fish in 2.5% of Parateq gaining the least weight. The highest percent growth rates were obtained from fish in control. The overall growth was significantly different between treatments and control. This study revealed that sublethal concentrations of toxicants will not only cause outright mortality
1888 PressRelease - Filmmaker Kit Farrell seeks interview subjects for documentary film profiling revolutionary discoveries in interspecies genetic research.
The lower cost and enhanced speed of Internet development projects should particularly encourage financial executives to empower first-line managers to take the initiative rather than wait for corporate level approval of every e-commerce experiment.
A related element of e-commerce experimentation is that Cisco did not feel compelled to invest heavily in calculating the estimated financial benefits of the experiment. First, it would have been impossible at the early stage to develop reasonable estimates
Use of greenhouse cultures accompanied by new techniques such as soilless or hydroponic culture on the one hand improves suitable control of plants nutrition and on the other hand it has created a great progress in greenhouse productions. In order to greenhouse tomato cultivar of Hamra was cultured in a hydroponic system and effect of micronutrients different levels was studied on it. The experiment design was as randomized complete block with five treatments and four replications. Experimental treatments were included: Lack of micronutrients application, Full application of sulfate manganese (4.06 mg/lit), Full application of sulfate zinc (4.42 mg/lit), 50% sulfate manganese (2.03 mg/lit) + 50% sulfate zinc (2.21 mg/lit) and Full application of sulfate manganese + Full application of sulfate zinc. The results showed that the highest fresh fruit yield, fruit dry matter percentage and content of Mn and Zn in fruit obtained from full application Mn, Zn and Mn + Zn. However micronutrients different levels had significantly effect on content of nitrogen, but they haven’t significantly effect on fruit size of tomato. Key words: Micronutrients, Tomato, Hydroponic culture, Yield.

Greenhouse tomatoes (Lycopersicon esculentum Mill.) were grown in a glass greenhouse at the Seminole Com munity College Horticultural Unit in Sanford, FL for two grow ing seasons (1996-97,1997-98) to determine the feasibility of a passive non-circulating, low-tech water culture system. Water and nutrients were added to troughs lined with 6-mil poly and covered by 4' x 8' insulation panels. Tomatoes in 4" azalea pots were placed in holes on the panels so that the bottom of the pots barely touched the water. An air space was maintained below the panel. Marketable yields during 13 weeks of harvest averaged 13.6 lbs. per plant the 1st season and 9.4 lbs. per plant the 2nd season. Marketable yields and plant vigor de clined when daytime greenhouse temperatures were consis tently over 90 F in June of 1997 and May of 1998. No significant yield differences were found between tomato cvs. Trust and Match. Suspending a screen in the water for root attachment did not significantly affect yields. The simple system design and maintenance makes it suitable for homeowner, hobbyist, or school demonstration applications provided that ideal tem peratures for greenhouse tomatoes can be maintained. Introduction New passive hydroponic systems were developed at the Asian Vegetable Research Center in Taiwan (Anon., xxxx) and studied further by B.A. Kratky and colleagues at the Uni versity of Hawaii (Kratky et al., 1988; Kratky, 1993; Kratky, 1996). These systems are low tech and relatively inexpensive compared to traditional hydroponics. Preliminary work in Florida (Fedunak and Tyson, 1997) found that short season lettuce crops performed well in a passive hydroponic system.
