TL;DR: Evidence is presented here that half-lives of proteins are also related to their isoelectric points, and that in mammalian cells proteins of large molecular weight are degraded more rapidly than small ones.
Abstract: Previous studies have shown that in mammalian cells proteins of large molecular weight are degraded more rapidly than small ones. Evidence is presented here that half-lives of proteins are also related to their isoelectric points. A double-isotope method was used to compare degradative rates of soluble proteins separated by isoelectric focusing. In rat liver, skeletal muscle, kidney, and brain, more rapid rates of catabolism were found for acidic protein fractions than for neutral or basic ones. Acidic proteins also tended to be degraded faster in several mouse tissues. A literature survey confirmed this trend. For 22 proteins from rat liver, a highly significant correlation was found between rates of degradation and isoelectric points (r = 0.824; P less than 0.01). This relationship between isoelectric point and half-life appears to be distinct from that between protein size and half-life.

TL;DR: The literature on the materials and metallurgical aspects of piston ring scuffing of internal combustion engines and gas compressors is reviewed in this article, where the role of material properties, surface treatments, metallographic changes in service and their effect on the phenomena are outlined.
TL;DR: The results, together with a literature survey on the anticholinergic effects on neuroleptic-induced catalepsy and inhibition of avoidance behavior, are related to biochemical findings and clinical effects.
Abstract: Haloperidol (0.08 mg/kg) or fentanyl (0.16 mg/kg) injected subcutaneously suppressed bar-pressing for brain-stimulation in rats, implanted with electrodes in the lateral hypothalamic area of the medial forebrain bundle. Increasing doses: 0.04, 0.16, 0.63 and 2.50 mg/kg of the central anticholinergic dexetimide gradually antagonized the haloperidol effects. The highest dose of dexetimide did not reduce the fentanyl-induced inhibition. The results, together with a literature survey on the anticholinergic effects on neuroleptic-induced catalepsy and inhibition of avoidance behavior, are related to biochemical findings and clinical effects.

TL;DR: A literature survey suggests that a high myocardial lipoprotein lipase together with a low hepatic lipase activity can predispose for atherosclerosis, and it is likely that a combination of high circulating triglyceride levels with a high glucagon/insulin ratio is atherogenic.
TL;DR: It is shown that a few experimentally chosen species of free‐living nematodes transmit in their intestine, and through defecation, that spread saprophitic plant pathogenic and human enteric bacteria and also spores of plant pathogen fungi, mycoplasma, phages of bacteria and algae.
Abstract: This paper gives a literature survey of the role of free‐living nematodes as disseminators of human and plant diseases. It is shown that a few experimentally chosen species of free‐living nematodes transmit in their intestine, and through defecation .spread saprophitic plant pathogenic and human enteric bacteria and also spores of plant pathogenic fungi, mycoplasma, phages of bacteria and algae. Nematodes protect them from chlorination.
TL;DR: The status of the morphologically intermediate strains between Lemna gibba and Lemna minor is discussed and it is suggested that the latter should be considered as intermediate between the former.
TL;DR: In this article, no work on Japanese peasant uprisings has been published English since Hugh Borton's study in 1938, which is the only English work on the subject.
Abstract: Turbulent years before and after the Meiji Restoration in 1868 have been one of the most extensively written pages of Japanese history. Much work has been carried out on the revolutionary samurai and the aspiring merchants who implemented the upheaval. Curiously, however, revolts and rebellions which erupted at more popular levels, such as peasant uprisings and urban mass disturbances during this period, have drawn little scholarly attention. According to the literature survey of Irwin Scheiner, no work on Japanese peasant uprisings has been published English since Hugh Borton's study in 1938.

TL;DR: In this article, the fracture behavior of fiber reinforced composites is discussed and a literature survey is presented in which three elements are discussed: fracture analysis, stress-strain characterization, and failure analysis.
Abstract: A fundamental investigation of the fracture behavior of fiber reinforced composites is discussed. It is suggested that experimental and analytical investigations should compliment each other. Further, it is suggested that in order to understand and mathematically model composite fracture it is necessary to explore, understand and characterize the stress-strain behavior of each type of laminate tested from initial loading to incipient fracture. That is, it is not only necessary to perform fracture studies but it is necessary to perform stress-strain characterization and failure studies as well. For this reason a literature survey is presented in which these three elements are discussed. An experimental program to determine tensile properties of unnotched and notched unidirectional and multi-directional laminates composed of Hercules AS Fiber and 3501 Resin is described. Experimental unnotched moduli and strengths are presented, discussed and compared to lamination theory predictions. It is shown that rate effects are small and that lamination theory gives good results for moduli but not for strengths.
TL;DR: The question arose whether the larch may be exceptional in this respect within the Pinaceae, or even among the Gymnospermae, and leaves of a 46 species of gymnosperms were subjected to a screening for C-glycoflavonoids occurring as major constituents.

TL;DR: In this article, a survey of previous work related to ball rolling and details of a short experimental investigation of the plastic deformation of Plasticine bars during rolling in a hand-driven mill are presented.
Abstract: A preliminary study was made of the process of rolling balls from cylindrical bar stock using Plasticine and tellurium lead as model materials. This paper includes a comprehensive literature survey of previous work related to ball rolling and details of a short experimental investigation of the plastic deformation of Plasticine bars during rolling in a hand-driven mill. Roll separating force and torque were measured when bars of tellurium lead in. in diameter were rolled to balls of 9 mm nominal size on a power-driven helical ball rolling mill. The plastic deformation modes of the Plasticine bars as they progressed through the mill to their final ball shape are also discussed.

TL;DR: In this paper, the brittle fracture characteristics of graphite-epoxy composites subjected to impact are investigated and a literature survey on failure theories for brittle, orthotropic, and anisotropic materials is presented.
Abstract: : The principal objectives of this program were (1) to establish how the brittle fracture characteristics of graphite-epoxy composites subjected to impact are influenced by such parameters as fiber and matrix properties, fiber orientation, stacking sequence, laminate thickness, curvature effects and interleaving effects and (2) to recommend solutions to the brittle fracture problem. To accomplish these objectives, a three-phase program was conducted. Phase I involved a literature survey on the experimental and theoretical work on the brittle fracture of composites subjected to impact as well as a literature survey on failure theories for brittle, orthotropic, and anisotropic materials. In Phase II, available computer solutions such as SAAS III, ASAAS and CYLINDER were modified and/or extended to the problems. In Phase III the test plan was implemented, which involved fabrication and impact testing of specimens. Types of graphite fibers used in the experimental program included Thornel 300, Modmor II and Celion GY-70. Types of resins investigated included 5208 epoxy, ERLA 4617 and polysulfone.

TL;DR: In this paper, a specific model was proposed which, in addition to varying turbulence intensity (rms velocity), varies the atmospheric turbulence scale length to achieve compatibility with real atmospheric turbulence.
Abstract: The background information in establishing several proposed atmospheric turbulence models for use on motion based aircraft simulators was documented. A specific model was proposed which, in addition to varying turbulence intensity (rms velocity), varies the atmospheric turbulence scale length to achieve compatibility with real atmospheric turbulence. With a suitable combination of scale length and intensity distribution, the model will simulate various atmospheric conditions characterized by altitude, stability, and terrain. The model is mechanized to be included in a flight simulator experiment in order to determine to what extent the pilots are sensitive to changes in atmospheric conditions and the realism of the model. The following topics were covered: literature survey, presently used techniques, proposed model, and simulation details.
