The physical principles underpinning self-organization in plants (2016)
Journal Article
Turner, P., & Nottale, L. (2017). The physical principles underpinning self-organization in plants. Progress in Biophysics and Molecular Biology, 123, 48-73. https://doi.org/10.1016/j.pbiomolbio.2016.09.003

We present evidence based theory for the emergence of plant structure in which CO2 is not only the source of carbon for plant growth, but also plays a critical role as a source of charge (ionization), with charge density dictating plant structures at...

A New Ab Initio Approach to the Development of High Temperature Superconducting Materials (2016)
Journal Article
Turner, P., & Nottale, L. (2016). A New Ab Initio Approach to the Development of High Temperature Superconducting Materials. Journal of Superconductivity and Novel Magnetism, 29(12), 3113-3118. https://doi.org/10.1007/s10948-016-3756-z

We review recent theoretical developments, which suggest that a set of shared principles underpin macroscopic quantum phenomena observed in high temperature superconducting materials, room temperature coherence in photosynthetic processes and the eme...

The origins of macroscopic quantum coherence in high temperature superconductivity. (2015)
Journal Article
Turner, P., & Nottale, L. (2015). The origins of macroscopic quantum coherence in high temperature superconductivity. Physica C: Superconductivity and its Applications, 515, 15-30. https://doi.org/10.1016/j.physc.2015.04.006

A new, theoretical approach to macroscopic quantum coherence and superconductivity in the p-type (hole doped) cuprates is proposed. The theory includes mechanisms to account for e-pair coupling in the superconducting and pseudogap phases and their in...

Strategic and tactical options for manageing the quality and value of eucalypt plantation resources. (2001)
Conference Proceeding
Turner, P. (2001). Strategic and tactical options for manageing the quality and value of eucalypt plantation resources.

The paper outlines options for managing the quality and value of eucalypt plantation resources. It begins with the hypothesis that variation is the largest single issue with regard to wood quality and that the extent of variation creates both the big...

An industrial evaluation of a stand level grading system for Pinus patula. (2001)
Journal Article
Turner, P., Megown, K. A., Grzeskowiak, V., Megown, R. A., Pauck, J., & Alborough, D. (2001). An industrial evaluation of a stand level grading system for Pinus patula. Southern African forestry journal, 190(1), 105-114. https://doi.org/10.1080/20702620.2001.10434123

This paper reports on progress made in the development and implementation of a stand level wood quality grading system for P. patula identified for processing in Mondi Merebank's stone ground wood and thermo-mechanical pulp lines. The grading system... Read More about An industrial evaluation of a stand level grading system for Pinus patula..

A feasibility study on the development of an integrated manufacturing planning and control system in the South African Sawmill Industry (1999)
Journal Article
Kapp, S. B., Price, C. S., Turner, P., & Vermaas, H. F. (1999). A feasibility study on the development of an integrated manufacturing planning and control system in the South African Sawmill Industry. Southern African forestry journal, 184(1), 80-87. https://doi.org/10.1080/10295925.1999.9631215

A feasibility study was conducted to assess the potential application of an integrated manufacturing planning and control (MPC) system within the South African sawmill industry. Implementation of such a system could enhance the international competit...

Treatment of timber products with gaseous borate esters: Part 2. Process improvement (1998)
Journal Article
Turner, P., & Murphy, R. J. (1998). Treatment of timber products with gaseous borate esters: Part 2. Process improvement. Wood science and technology, 32(1), 25-31. https://doi.org/10.1007/bf00702557

This paper forms a continuation of the work on treatment of timber products with gaseous borate esters. Turner and Murphy (1995) in an earlier paper indicated that gas flow rate into the wood substrate was the principle factor limiting the rate of bo...

Maximising Value of the Plantation Resource: Part 1. Development of a Log Grading Proposal for Pruned Softwood logs (1996)
Journal Article
Turner, P., & Price, C. S. (1996). Maximising Value of the Plantation Resource: Part 1. Development of a Log Grading Proposal for Pruned Softwood logs. South African forestry journal, 176(1), 29-33. https://doi.org/10.1080/00382167.1996.9629707

There are at present strong market pressures to increase the price of pruned softwood logs in South Africa. However, there is currently no equitable basis on which to price pruned logs, as their value can vary enormously, depending upon a number of i...

Treatment of timber products with gaseous borate esters: Part 1. Factors influencing the treatment process (1995)
Journal Article
Turner, P., & Murphy, R. (1995). Treatment of timber products with gaseous borate esters: Part 1. Factors influencing the treatment process. Wood science and technology, 29(5), 385-395. https://doi.org/10.1007/bf00202586

Several factors which influence the treatment of timber products with vapour phase preservatives such as borate esters are considered. Gas flow rate through the substrate was found to be a significant factor limiting both preservative penetration and... Read More about Treatment of timber products with gaseous borate esters: Part 1. Factors influencing the treatment process.

A vapour phase preservative treatment of manufactured wood based board materials (1989)
Journal Article
Murphy, R. J., & Turner, P. (1989). A vapour phase preservative treatment of manufactured wood based board materials. Wood science and technology, 23(3), 273-279. https://doi.org/10.1007/bf00367740

The preservative treatment of four different wood based board materials using an esterified borate applied in the vapour phase was investigated. Under optimum conditions complete impregnation via the board faces was achieved in all boards treated. Bo...
