The empirical relationship between the managerial conduct and internal control activities in South African small, medium and micro enterprises

open access: yesSouth African Journal of Economic and Management Sciences, 2017
Background: Although South African small, medium and micro enterprises (SMMEs) play an imperative role in the stimulation of the national economy, previous research studies show that these business entities have severe sustainability problems as ...

Is external control important for internal control?

open access: yesJournal of Sociocybernetics, 2016
In cybernetics, the basic assumption is that systems aim for control.But what and how are they controlling? I dierentiate two categories ofcontrol: internal and external control. In external control, one starts fromoutside, and tries to determine the environment completely. While withinternal control, one's own aspirations are taken as a starting point,

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

open access: yesFEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Internal control of the Schrödinger equation

open access: yesMathematical Control & Related Fields, 2014
In this paper, we intend to present some already known results about the internal controllability of the linear and nonlinear Schr dinger equation. After presenting the basic properties of the equation, we give a self contained proof of the controllability in dimension 1 using some propagation results.

Helicopter internal noise control: Three case histories [PDF]

open access: yes
Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle.

Construction of hyperthermostable d‐allulose 3‐epimerase from Arthrobacter globiformis M30 using the sequence information from Arthrobacter psychrolactophilus

open access: yesFEBS Open Bio, EarlyView.
d‐Allulose can be produced from d‐fructose by d‐allulose 3‐epimerase. Based on sequence homology information, we successfully engineered thermostable mutants with the protein engineering method. By integrating positive mutations, we constructed an enzyme that exhibits hyperthermostability without a loss in the activity.
