The use of almond-shell biomass ash (ABA) as an alternative component to the commercial reagents used in activation blast furnace slag (BFS) systems is investigated. presence its chemical composition a high content K2O indicates that it can alkalinize medium. 100% waste-based mixtures ABA/BFS were studied by micro- and macrostructural tests. A compressive strength 44 MPa was achieved mortar wit...

Welcome to the seventh edition of “All About Almonds”, Almond Bud Initiation and Development. Fact sheets are distributed to almond growers via email and fax, in addition to being made available for download from the levy payers’ access page on the ABA website: www.australianalmonds.com.au (follow links to the login section of the “industry” page). The information provided in these fact sheets ...

Abstract In this study, to remove Cr(VI) from the solution environment by adsorption, almond shell was pyrolyzed at 400 and 500 °C turned into biochar (ASC400 ASC500) composite adsorbents were obtained coating these biochars with chitosan (Ch-ASC400 Ch-ASC500). The resulting characterized using Fourier transform infrared (FTIR) spectroscopy; Brunauer, Emmett, Teller (BET) surface area; scanning...

Aflatoxin contamination of nuts is an increasing concern to the consumer's health. Portugal is a big producer of almonds, but there is no scientific knowledge on the safety of those nuts, in terms of mycotoxins. The aim of this paper was to study the incidence of aflatoxigenic fungi and aflatoxin contamination of 21 samples of Portuguese almonds, and its evolution throughout the various stages ...

Severe decline of almond trees has recently been observed in several orchards on the island of Mallorca (Balearic Islands, western Mediterranean Sea). However, the identity of the causal agents has not yet been investigated. Between August 2008 and June 2010, wood samples from branches of almond trees showing internal necroses and brown to black vascular streaking were collected in the Llevant ...

The grass sharpshooter, Draeculacephala minerva Ball (Hemiptera: Cicadellidae), is a very common and often abundant grass-feeding leafhopper in California. Its population dynamics and ability to transmit Xylella fastidiosa were monitored over a 2-yr period in California's San Joaquin Valley. Collections of individuals from natural populations in irrigated pastures and alfalfa, Medicago savita L...

Xylella fastidiosa causes disease in many commercial crops, including almond leaf scorch (ALS) disease in susceptible almond (Prunus dulcis). In this study, genetic diversity and population structure of X. fastidiosa associated with ALS disease were evaluated. Isolates obtained from two almond orchards in Fresno and Kern County in the San Joaquin Valley of California were analyzed for two succe...

Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...
