EFFECT OF MINERAL AND BIOFERTILIZATION TREATMENTS ON: 2- CORMS PRODUCTIVITY AND CHEMICAL CONSTITUENTS OF GLADIOLUS CV. WHITE PROSPERITY

A field experiment was conducted at Nursery of Ornamental Plants, Fac. Agric., Minia Univ. during 2013/2014 and 2014/2015 to investigate the effect of NPK (0, 50, 75 and 100% of recommended dose) and biofertilizers (phosphorein and/or E.M.) on corm and cormels productivity, as well as, chemical constituents of gladiolus cv. White Prosperity. The obtained results indicated that, corm diameter, corm dry weight, number of cormels/plant, cormels dry weight/plant, as well as, chemical constituents (N, P, K and total sugars % in corms and total chlorophyll in leaves) were significantly increased with all levels of NPK in comparison with control. The highest values were obtained with NPK 100%. All biofertilizer treatments significantly increased corm and cormels productivity, as well as, either chemical constituents in comparison with the control. Phosphorein + E.M. was more effective in this concern. The interaction treatments were significant with the highest values being obtained due to NPK 75% in combination with phosphorein + effective microorganisms (E.M.)

RESPONSE OF GLADIOLUS CV. CARMEN TO COMPOST, BIOFERTILIZATION AND SOME VITAMIN TREATMENTS

A field experiment was carried out during the twosuccessive seasons of 2012/2013 and 2013/2014 to study the effect ofcompost and biofertilizers, as well as, some vitamins and theirinteraction on Gladiolus grandiflorus cv. Carmen plant.Results showed that vegetative growth (leaf length, number ofleaves/plant and dry weight of leaves/plant), flowering aspects (lengthof spike, number of florets/spike and lower floret diameter) and cormsproductivity (corm diameter, corm dry weight and number of cormelsper plant) were gradually increased by increasing the level of compostfertilizer.All biofertilizers and vitamins treatments significantly increased allvegetative growth characters, flowering parameters and corm andcormels productivity in comparison with the control. Effectivemicroorganisms (E.M.) + active dry yeast (A.Y.) treatment seemed tobe more effective than other treatments in this concern.The use of high level of compost (21 ton/fed) in combination withcombined biofertilizers noticeably improved the different vegetativegrowth characters, flowering parameters and corms productivity ofgladiolus

RESPONSE OF POPULUS ALBA, L. TRANSPLANTS TO COMPOST, BIOFERTILIZERS AND MINERAL NPK FERTILIZATION

This investigation was conducted to investigate the response of Populus alba transplants to compost fertilization at four levels and Bio. and/or mineral NPK treatments (control, phosphorein, effective microorganisms (E.M.), phosphorein + effective microorganisms, a mixture of Bio. (phosphorein + E.M.) + 75% NPK and mineral NPK, full dose) on vegetative and root growth parameters and some chemical constituents. The obtained results indicated that, transplant height, stem diameter, whole transplant fresh and dry weights, main root length, fresh and dry weights of roots, as well as, chemical constituents including total chlorophylls, percentages of N, P and K were gradually increased by increasing the levels of compost fertilizer. Biofertilizers and/or mineral NPK fertilization treatments significantly increased all the previous parameters. Bio. + 75% NPK dose followed by mineral NPK (full dose) treatments were the most effective in this concern. The interaction between compost and Bio. and/or mineral NPK fertilization treatments was significant for vegetative and root growth parameters with the highest values for vegetative and root growth traits being obtained due to either compost fertilizer in combination with Bio. + 75% NPK dose or with mineral NPK (full dose

EFFECT OF MINERAL AND BIOFERTILIZATION TREATMENTS ON: 1- VEGETATIVE GROWTH AND FLOWERING OF GLADIOLUS PLANTS

A field experiment was carried out at Nursery of Ornamental Plants, Fac. Agric., Minia Univ., Egypt during the two successive seasons of 2013/2014 and 2014/2015 to investigate the effect of NPK (0, 50, 75 and 100% of recommended dose) and biofertilization (phosphorein and/or E.M.) treatments on growth and flowering of Gladiolus grandiflorus cv. White Prosperity. Results showed that vegetative growth traits (leaf length, number of leaves/plant and leaves dry weight/plant) and flowering parameters (length of spike, rachis length, number of florets/spike, first floret diameter and fresh weight) were gradually increased by increasing the levels of NPK fertilizer. Also, all biofertilization treatments significantly increased all vegetative growth parameters as well as all flowering characters in comparison with the control. Phosphorein plus effective microorganisms (E.M.) treatment was more effective in this concern. It was found that the use of NPK (75% from the recommended dose) plus phosphorein + E.M. improved the growth and flower production of gladiolus plants compared with the other treatments

EFFECT OF FYM, MINIA AZOTEIN, SALICYLIC AND ASCORBIC ACIDS TREATMENTS ON GROWTH AND ESSENTIAL OIL PRODUCTION OF CORIANDER (CORIANDRUM SATIVUM, L.) PLANTS

A field experiment was carried out during 2013/2014 and 2014/2015 seasons at the Experimental Farm, Fac. of Agric., Minia Univ. to investigate the effect of FYM (0, 10, 15 and 20 ton/fed), Minia Azotein (M.A.) as biofertilizer containing N-fixing bacteria, salicylic acid (Sal.), ascorbic acid (Asc.), M.A. + Sal. and M.A. + Asc. on the vegetative growth and essential oil productivity  of coriander plants. The obtained data revealed that vegetative growth characters (plant height, number of branches/plant and herb dry weight/plant) and essential oil production (oil % as well as oil yield/plant and /fed) were significantly increased due to the application of all levels of FYM over those of control treatment. The maximum values were recorded at the high level of FYM (20 ton/fed). Vegetative growth characters and essential oil productivity parameters were significantly augmented as a result of using the different five treatments. The most effective treatments in this concern were Minia Azotein (M.A.) + salicylic acid (at 50 ppm) followed by Minia Azotein (M.A.) + ascorbic acid (at 50 ppm) without significant difference between such superior treatments. While, M.A. plus either salicylic acid or ascorbic acid gave the highest essential oil % and oil yield /plant and /fed.  It could be recommended to supply Coriandrum sativum plants with FYM at 20 ton/fed in combination with M.A. + salicylic acid or ascorbic acid each at 50 ppm to give the high productivity and the safety, not only for human but also for the environment in which we live

Medical system based on thermal optical system and neural network

Military personnel in the training or operational phases always need constant medical examination, but the presence of efficient medical care is difficult to implement in real-time for such cases. A wireless system for thermal tracking of soldiers was proposed, as well as tracking their vital signs in real time. Thermal cameras are used with an optical system designed to increase the accuracy of the thermal images captured as the change in the electro-cardiogram, heart rate, and temperature measurements are measured using a specially designed circuit. The results from both the thermal system and the biometric system are combined and sent to a computer for analysis using a model prepared with neural network technology. The proposed system was tested, and a database was created for 127 males and 110 females during training and rest times. The neural network model achieved a response time of 85 seconds until the release of the final analysis, and the accuracy of the proposed tracking system is 96%. The main contribution of this paper is the design of an integrated portable system for rapid, in-field, real-time military medical diagnostics

EFFECT OF NITROGEN SOURCES AND ASCORBIC ACID ON GROWTH AND ESSENTIAL OIL PRODUCTION OF GERANIUM (PELARGONIUM GRAVEOLENS, L.) PLANTS

The experiment was conducted during two successive seasons (2012/2013 and 2013/2014) in the nursery of ornamental plants and the Laboratory of Floriculture, Fac. of Agric., Minia Univ. The aim of this work is to study the effect of bio-mineral nitrogen and ascorbic acid (50, 100 and 150 ppm) on growth and essential oil production of geranium plants. Results showed that non-significant differences between mineral N (100%) and mineral N (75%) + Minia Azotein (Azotobacter strain) on growth and essential oil production of plants. The effect of high concentration (150 ppm) of ascorbic acid was superior to that other two concentrations (medium and low) on increasing plant growth and essential oil productivity. The plants fertilized with mineral N (75%) plus Minia Azotein (Azotobacter strain) and spraying with 150 ppm ascorbic were equal (growth and essential oil production) with plants received 100% N plus 150 ppm ascorbic acid

Selective Spectrophotometric and Spectrofluorometric Methods for the Determination of Amantadine Hydrochloride in Capsules and Plasma via Derivatization with 1,2-Naphthoquinone-4-sulphonate

New selective and sensitive spectrophotometric and spectrofluorometric methods have been developed and validated for the determination of amantadine hydrochloride (AMD) in capsules and plasma. The methods were based on the condensation of AMD with 1,2-naphthoquinone-4-sulphonate (NQS) in an alkaline medium to form an orange-colored product. The spectrophotometric method involved the measurement of the colored product at 460  nm. The spectrofluorometric method involved the reduction of the product with potassium borohydride, and the subsequent measurement of the formed fluorescent reduced AMD-NQS product at 382  nm after excitation at 293  nm. The variables that affected the reaction were carefully studied and optimized. Under the optimum conditions, linear relationships with good correlation coefficients (0.9972–0.9974) and low LOD (1.39 and 0.013 μg mL−1) were obtained in the ranges of 5–80 and 0.05–10  μg mL−1 for the spectrophotometric and spectrofluorometric methods, respectively. The precisions of the methods were satisfactory; RSD ≤2.04%. Both methods were successfully applied to the determination of AMD in capsules. As its higher sensitivity, the spectrofluorometric method was applied to the determination of AMD in plasma; the recovery was 96.3–101.2 ± 0.57–4.2%. The results obtained by the proposed methods were comparable with those obtained by the official metho

High-Content Lignocellulosic Fibers Reinforcing Starch-Based Biodegradable Composites: Properties and Applications

Natural source-based composites became promising substitutes and synthetic petrochemical-based counterparts. So far, thermoplastic starch and lignocellulosic fibers are the most common materials for making such eco-friendly ?green? materials. Low cost, abundance, and renewability are the factors that lead to deploying these two types of materials. In this chapter, we are conducting further analysis for previously published results of six types of high-content natural fiber-reinforced starch-based composites. All composites were prepared by compression molding under pressure from 5 to 20 MPa and temperature from 130 to 160°C. Composites exhibited highest tensile strength and modulus of elasticity at fiber weight content from 50 to 70%, and then mechanical properties deteriorated significantly at 80% fiber content due to the insufficient starch resin. For instance, the tensile strength was boosted up from 2-12 MPa for thermoplastic starch to reach 55, 45, 32, 28, 44, 365 MPa for flax, bagasse, date palm fiber (DPF), banana, bamboo, and hemp composites, when fiber content was increased from 0% to the optimum fiber content (50-70%). Kelly-Tyson (random 2d) was the optimum model to predict random fiber composite. Increasing the fiber content and choosing a fiber with high cellulose content significantly improve the moisture resistance of the composites. Fick’s law of diffusion predicted the water uptake property successfully. The thermal stability of composites was improved with increasing the fiber weight content as well. This is attributed to the high thermal stability of cellulose when compared to starch. Properties exhibited by starch-based high-content natural fiber composite are promising for many industrial and biomedical applications
