Historically “Lightweight Cryptography” has focused on symmetric schemes, yet asymmetric methods can also work effectively in these environments. Specifically, the Walnut Digital Signature Algorithm (WalnutDSA) provides a public-key signature scheme that verifies signatures significantly faster than ECC in both software and hardware, even in small, constrained environments and is resistant to a...

In a young walnut orchard planted on black walnut rootstock, and stunted as a result of root lesion nematode feeding treatments are being applied in an effort to invigorate tree growth and/or significantly reduce the nematode population. Treatments began in 1989 and include: (1) Spring grafting two paradox seedlings to the existing trees trunk (llinarching")i(2) application of Nemacur 3 nematoc...

Annual and perennial weed control trials were retreatedin Butte, Solano and Yolo counties. The diversified locations continue to provide a vital basis for applicable information on walnut tree tolerance to herbicides and on weed control efficacy. Herbicidal control of a wide spectrum of annual or perennial grass and broadleaf plants has been evaluated for the winter and summer periods of 1980. ...

The study was conducted at 10 – yearsold walnut orchard at Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan(H.P.) to find out the effect of integrated nutrient management on leaf nutrient status of walnut (Juglans regia L.). There were 13 different treatment combinations of organic and inorganic fertilizers. Treatments were applied on per tree basis. Among the treatments re...

Shallow bark canker incited by Brenneria nigrifluens is considered one of the most dangerous diseases which can cause a significant reduction in walnut and timber production.  During spring and summer of 2019, walnut gardens were surveyed for symptoms like leaf spot, fruit, and stem canker from four different regions of Golestan province located in Iran. A set of 11 Gram-negative bacteria were ...

The ground cover in plantings of walnut and other hardwoods can substantially affect tree growth and seed production. The number of alternative ground covers that have been suggested for establishment in tree plantings far exceeds the number that have already been tested with walnut and other temperate hardwoods. Knowing how other hardwood species respond to ground covers and which have respons...

The traditional method in Iran of cracking walnut manually, using harmer or knife cutter is laborintensive, slow and tedious; besides, most mechanical crackers do not give satisfactory results in terms of kernel extraction quality. A prototype machine was developed to crack walnut. A walnut cracker was designed, constructed and tested to evaluate its performance. The cracker, which consists of ...
