The price paid for corn is usually based on 15.0 or 15.5 percent moisture content. However, corn must be dried below 13 percent moisture to ensure safe storage for a year or more. In the U.S., such stored corn cannot be directly remoistened before selling it, but it can be mixed with moist new-crop corn. Accurate moisture measurement of mixtures of dry and moist corn is important to permit adjustment of blending ratios to maximize profitability, but grain moisture meters are less accurate for mixtures of wet and dry grain. This research evaluated the differences between dielectric-type moisture meter results for mixed and equilibrated corn samples at different moisture levels and different measurement frequencies. Equilibrated grain samples tended to give lower moisture results than recently mixed grain samples - especially in the 1 to 10 MHz region. These differences permitted detection of mixtures by using moisture measurements at two frequencies.

Transdermal patch is a drug delivery device in which the drugs are incorporated and is design in such a way that it releases the drug in sustained and at predetermined rate to deliver the drug through the skin to the systemic circulation painlessly. The aim of this research study was to formulate a controlled and sustained release transdermal matrix type patch of Methimazole. The matrix patch was prepared by solvent casting method using a various polymer in different concentration, HPMC (hydrophilic), Eudragit RL100 and Ethyl cellulose (hydrophobic) polymer. Total 9 prototype formulation were prepared and it was subjected for various evaluation test; weight uniformity, Folding endurance, thickness, Drug content, percent moisture content, percent Moisture uptake and In-vitro drug release study using Franz diffusion cell. The in-vitro CDR% data was fit into kinetics model to see the release kinetics from the patches. The Formulation F5 was choosen as a best formulation according to in-vitro drug release study. The in-vitro release was found 81.12 % in 12 hours, it followed zero order kinetics. The nature of polymer and concentration ratio of polymers plays a crucial role for obtaining a good transdermal patch design; therefore optimisation is very important step to formulate a desired TDDS. Therefore the result of the study encourages a further study and is hopeful that the present study would contribute to the recent pharmaceutical research for formulation development.

Abstract Nonchemical high-pressure steam treatments have been intensively researched and commercialized to produce chemical-free wood products with enhanced properties. However, the utilization of high-pressure steam involves vapor-phase reactions using high-temperature steam generated at the expense of high energy input. In this research, influences of reaction media (steam and hot-compressed water) and temperature (100°C and 140°C) during thermal treatment on physical properties and drying behavior of yellow-poplar (Liriodendron tulipifera) heartwood were compared. The length, width, and thickness of the samples were 22.53 mm, 17.18 mm, and 16.72 mm, respectively. After the treatment, the samples were dried under an isothermal temperature condition of 105°C. Data on moisture content and time of drying from drying experiments were fitted with unsteady-state molecular transport equations to calculate overall liquid diffusion coefficients. Dimensions, weight, and true volume of samples were measured for green, thermally treated, and dried samples and the values were used to calculate selected physical characteristics. Additionally, selected mechanical properties were evaluated for samples conditioned to 13 percent moisture content. Results showed that intensified hot-compressed water-treated and control samples had the highest and lowest saturated moisture contents (101% and 44%), respectively, immediately after treatments. Intensified steam-treated and control samples had the highest and lowest total porosity (95% and 82%), respectively. Furthermore, mild hot-compressed water-treated samples showed the greatest compression strength (47.8 MPa) at 13 percent moisture content. Except for steam treatment at 140°C, other treatments significantly decreased the diffusion coefficient. Collectively, samples treated with hot-compressed water at 100°C showed the most improved mechanical properties.

Abstract Containerized stock plants of Ilex crenata Thunb. ‘Rotundifolia’ were liquid-fertilized at least three times per week with nitrogen (N) at five rates (25, 50, 100,200, and 300 mg N/l) and in two forms (100% NH4NO3 or 50% NH4NO3 + 50% urea) in a factorial treatment design. Phosphorus and potassium were included in a constant ratio with N (100 N:15 P:50 K). Leaf and stem percent N levels were suboptimal at the lowest fertilizer rate and excessive at the highest fertilizer rate. Percent rooting of stem cuttings decreased linearly with fertilizer rate. With increasing fertilizer rates, total nonstructural carbohydrate (TNC) levels increased in leaves and remained constant in stems. Stem cutting percent moisture increased and was highly correlated with fertilizer rate. The form of N applied made no statistical difference in these trends. The decrease in percent rooting with increasing fertilizer rates was attributed to increases in shoot growth activity and decreased tissue maturation.

Cotton fiber moisture content is one of the most important factors that affects the operation of the cotton ginning process. A system has been developed that measures cotton’s dielectric constant and density with sufficient accuracy to indicate moisture content of the fiber during processing. An electronic capacitor and a pneumatic density sensor supply measurements to a microprocessor which combines them into a predicted moisture content. Tests showed that these predicted readings are more precise than conventional oven-moisture determinations and that they can be used for process control in the ranges from 6.5- to 12-percent moisture content.

In Katsina metropolitan, a variety of poultry feeds are available, and the quality and standards of these feeds are critical for the production of eggs and meat. As a result, the quality of selected chicken feeds sold in Katsina metropolitan was assessed by performing proximate analysis using AOAC methodology. Super starter, grower concentrate, broiler finisher, broiler starter, broiler super starter, layer mesh, grower mesh, and layer concentrate were among the samples used. The percentage mean to standard deviation was used to express the findings. The crude protein content of the diets studied ranged from 0.46 ± 0.00 percent to, 8.24± 0.02 percent, ash content 6.31± 0.01 percent – 33.30± 0.04 percent, crude fiber content 1.03 ±0.00 percent – 3.21± 0.00 percent, lipid content 0.11± 0.00 percent, 2.30 ±0.00 percent, moisture content 4.28 ±0.25 – 6.66 ±0.78 percent, and carbohydrate content 51.78± 2.68 – 83.72 ±0.57 percent. Although there was variation in the mean and standard deviation levels among the samples analyzed, such variations were not statistically significant (P>0.05) according to a one-way analysis of variance (ANOVA) for the difference in the mean levels of parameters evaluated in eight samples

SummarySixteen rennet casein samples and the corresponding sixteen cheese analogues made from these caseins were obtained from a local processor. Following storage at 4°C for 6 months, pH 4·6-soluble N contents of the cheese analogues increased, while αs- and β-casein contents, elastic moduli and apparent relaxation times decreased. The β-casein and pH 4·6-soluble N contents of the 6 month old products were significantly correlated, both were significantly correlated with the plasmin (EC 3.4.21.7) contents of the corresponding rennet caseins from which the analogues were made and all three were significantly correlated with the rheological properties of the stored analogues. Of the compositional characteristics, only percent moisture in non-fat substance and percent fat in dry matter were significantly correlated (P < 0·05) with any of the proteolytic or rheological properties. The sixteen cheese analogues were also assayed at one time, when they ranged in age from 1 to 35 weeks, and highly significant interrelationships between plasmin activity, proteolysis and rheological properties were established. The results indicate that the plasmin content of rennet caseins had a significant influence on the proteolytic and rheological changes that occurred during storage of cheese analogues made from these caseins.

The aim of our research work was to isolate a biomaterial from Colocasia. esculenta and prepare phenytoin loaded mucoadhesive biofilms using this biomaterial. The biomaterial was isolated from C. esculenta tubers by an economical process. The isolated biomaterial was subjected to various physical evaluation, chemical tests as well as spectral analysis. The drug-biomaterial interaction study was performed to see if there was any interaction of biomaterial with phenytoin. Phenytoin loaded biofilms were prepared using biomaterial, flexicizer and other co- processing agents. The prepared biofilms were evaluated for physical appearance, weight, thickness, folding endurance, swelling index, surface pH, tensile strength, percent elongation, percent moisture uptake, percent moisture loss, vapor transmission rate and content uniformity. The mucoadhesivity of biofilms was investigated using rotating basket method. The in-vitro drug release study of biofilms was performed on static MS diffusion apparatus. The stability studies of biofilms were carried out at different conditions of temperature and relative humidity. The results were compared with the standard hydroxy propyl methyl cellulose (HPMC) and sodium carboxymethyl cellulose (Sodium CMC) films. The experimental results revealed that the phenytoin loaded biofilms of C. esculenta possessed excellent mucoadhesivity, sufficient stability as well as appreciable release characteristics. The best biofilm formulation was PK6 with a cumulative drug release of 95.35 % over 36 hours. Hence, C. esculenta biomaterial can serve as a potential film forming agent for transmucosal drug delivery systems.Dhaka Univ. J. Pharm. Sci. 15(2): 177-186, 2016 (December)

The present study was concerned with the preparation and evaluation of oral thin films of levosalbutamol sulphate (LS) is to avoid presystemic elimination by gastrointestinal degradation and first pass hepatic metabolism. The films were prepared using four different water soluble polymers in various proportions and combinations using propylene glycol as plasticizers. Total five formulations were developed and evaluated for the various physicochemical characteristics namely mass uniformity, thickness, folding endurance, density, surface pH, swelling index, disintegration time, content uniformity, in vitro release profile, percent moisture absorption and loss and ex vivo mucoadhesion time. Data of every parameter were taken in triplicate. Results of film thickness, mass, density and swelling index of medicated films of LS were found with relatively low standard deviation along with high folding endurance (>300). The surface pH of all films approached to the salivary fluid pH range (6.1~7.0). Disintegration time and content uniformity complied with standard for all formulations. Among the total five formulations, F-2 and F-5 followed first order release and F-1 and F-4 followed Higuchi release and F-5 followed zero order and hixon-crowell release. The residence time for mucoadhesion of the tested films ranged between 1 to 5 minutes. Percent moisture absorption and loss study revealed the excellent stability of the films in dried conditions and relatively low standard deviation indicated the stability also in humid conditions.Bangladesh Pharmaceutical Journal 20(1): 64-70, 2017

Abstract Four liquid insecticide evaluation studies were conducted at three sites in Beltsville, Uniontown, and Burkittsville, MD. Corn was planted no-till on 29 Apr and 15 May at Burkittsville and Beltsville, respectively. Conventionally tilled corn was planted at Uniontown I and II on 29 Apr and 13 May, respectively. Treatment plots were 4 rows × 50 ft arranged in a RCB with 3 replications. Furadan 4 F broadcast was applied with a COz backpack sprayer calibrated to deliver 21 gpa at 40 psi. Force 1.5 G was applied in a 7 inch band over the row with a hand powered bicycle wheel applicator. Both treatments were made at or near planting. Post-planting treatments of Furadan 4F were directed at the base of the plant in a 11 inch band during 8-10 Jun with a CO2 backpack sprayer delivering 12 gpa at 40 psi. Root damage was evaluated during 7- 12 Jun. Six roots were dug, washed, and rated in accordance to the Iowa 1-6 scale. Yields were determined by hand harvesting 50 ft of row. Percent moisture was measured for each plot and used to convert yields to 15.5%.
