1. The influence of separately and combined bentonite and kaolinite as binders for pelletization of NaA zeolite from coal fly ash
Abstract Pelletization of zeolitic materials is required to facilitate their practical industrial and commercial applications. Zeolite-NaA was synthesized from fly ash by the fusion method and shaped into spherical granules. Bentonite, kaolinite, and a combination of bentonite with kaolinite were tested as binders with different contents from 5 to 10 wt%. Th

2. Sorghum (Sorghum bicolor) Pellet Production and Characterization
ABSTRACT Pelletization is a technique used to compact biomass, generating a granulated material called pellets, with high energy density. The objectives of this work were to produce pellets made from Sorghum (Sorghum bicolor) residuals and to evaluate its quality. Firstly, the residuals were characterized, followed by the production of the pellets. An experi

3. Avaliação do farelo de mamona processado na alimentação de codornas japonesas. / Evaluation of castor meal processed in feeding of Japanese quail.
The experiments were conducted to evaluate the use of processed castor meal (FM) in diets of Japanese quail. Two experiments were conducted: the first was to determine the bromatological and the coefficients of metabolization of dry matter (CMMS), nitrogen (CMN) and gross energy (CMEB), as apparent metabolizable energy (EMA) and corrected for apparent nitrog

4. Peletização : estudo de processos de incorporação de princípios ativos em péletes inertes
O segmento farmacêutico demonstra um crescente interesse no processo de peletização, o qual consiste na aglomeração por via úmida de pós finos compostos de ativos e excipientes em pequenas unidades esféricas, com excelentes vantagens tecnológicas e terapêuticas. O objetivo do presente trabalho envolve o estudo de processos de incorporação de susp

5. Uso de complexo enzimÃtico em raÃÃes fareladas e peletizadas para frangos de corte / Use of enzyme complex in mash and pelleted diets for broiler chickens
Dois experimentos foram conduzidos para avaliar os efeitos da suplementaÃÃo enzimÃtica em raÃÃes de frangos de corte à base de milho e farelo de soja sob duas formas fÃsicas (farelada e peletizada) sobre desempenho, caracterÃsticas de carcaÃa, morfometria intestinal e digestibilidade dos nutrientes. Os tratamentos constituÃram-se de raÃÃes à bas

6. Pelletization of seeds of Raphanus sativus L. cv. Redondo Gigante with graphite for germination under water stress conditions
O efeito do estresse hídrico é dependente da presença de luz em sementes de rabanete. O efeito da peletização com grafite em pó foi analisado. Luz branca e vermelho-extremo são filtradas pelo grafite aumentando parcialmente a tolerância ao estresse hídrico de -0,77MPa em sementes peletizadas. Embora a luz vermelha também iniba a germinação em con

7. Direct pelletization in a rotary processor controlled by torque measurements. III. Investigation of microcrystalline cellulose and lactose grade
The aim of the present study was to investigate the use of different grades of microcrystalline cellulose (MCC) and lactose in a direct pelletization process in a rotary processor. For this purpose, a mixed 2- and 3-level factorial study was performed to determine the influence of the particle size of microcrystalline cellulose (MCC), (≈60 and 105 μm) and

8. Large-scale production and concentration of infectious Epstein-Barr virus.
Infectious Epstein-Barr virus (EBV) was produced from suspension cultures of P3HR-1 cells. A protocol for the scaled-up production and concentration of the virus was developed. Virus from the culture fluid was concentrated by continuous-flow pelletization or continuous flow with banding in sucrose. EBV prepared by pelletization yielded 1.7 X 10(4) infectious

9. Optimization of the pelletization process in a fluid-bed rotor granulator using experimental design
This study examined the effect of rotor speed, amount of water sprayed, and atomizing air pressure on the geometric mean diameter and geometric standard deviation of pellets produced in a fluid-bed rotor granulator using a 23 factorial design and an optimization technique.

10. Pellet manufacturing by extrusion-spheronization using process analytical technology
The aim of this study was to investigate the phase transitions occurring in nitrofurantoin and theophylline formulations during pelletization by extrusion-spheronization. An at-line process analytical technology (PAT) approach was used to increase the understanding of the solid-state behavior of the active pharmaceutical ingredients (APIs) during pelletizati

11. Influence of formulation and process parameters on pellet production by powder layering technique
The goal of the present study was to evaluate the influence of the formulation and operating conditions on pellet preparation by pan technique. To this end, a new pelletization process, typified by the application of powdered drug on sugar-based cores using the GS coating system was studied. Inert cores were intermittently treated with micronized drug powder

12. New method for large-scale growth; and concentration of the Epstein-Barr viruses.
Efficacious systems are described for the large-scale growth in tissue culture and concentration of infectious (P3HR-1) and transforming (B95-8) Epstein-Barr virus. Also recorded here are our updated procedures for growing stock cultures and protocols to harvest fluids containing biologically active virus which is infectious or transforming. Various methods
