TL;DR: In this paper, the authors presented a table for the selection of single sampling plans for variables using three forms of acceptance criteria (sigma-method, s-method and R-method) which match the Operating Characteristic performance of MIL-STD-105D plans.

TL;DR: It is suggested that ecotypic variations in the size and length of the ovipositor of these parasitoids could be considered as an example of biological coevolution of the hosts and the chalcid egg parasitoid in Tingidae.
Abstract: Natural enemies of the Tingidae have been enumerated. The Chalcid egg parasitoids, reported here from 23 species belonging to 20 genera of Tingidae, are three species of Trichogrammatidae (Lathromeromyia (Lathromeromina) tingiphaga, Lathromeromyia sp., Epoligosita (Epoligositina) duliniae) and two species of Mymaridae (Parallelaptera sp., Erythemelus empoascae). Parallelaptera sp. attacks about 20 species whereas E. (E.) duliniae is specific to Dulinius conchatus. The size of the parasitoid is almost related to the size of the body of the host egg and the length of the ovipositor invariably corresponds with the height of the chorionic collar of the host egg. It is suggested that ecotypic variations in the size and length of the ovipositor of these parasitoids could be considered as an example of biological coevolution of the hosts and the chalcid egg parasitoids in Tingidae. There is no Superparasitism in Tingidae.

TL;DR: In this paper, the optical and structural properties of the thin tellurium oxide films have been studied and from the variations in the properties with respect to the formation conditions the evaporation characteristics of TeO2 have been discussed.
Abstract: Thin films of tellurium oxide have been formed by evaporating TeO2 with different boat materials (molybdenum and tantalum) in a high vacuum and at different oxygen partial pressures. The optical and structural properties of the films have been studied. From the variations in the properties with respect to the formation conditions the evaporation characteristics of TeO2 have been discussed.

TL;DR: Rhinocoris fuscipes Fabr, starts laying maroon coloured elongate eggs in batches at the age of 28-3 days, eggs are glued to each other and to the substratum with cementing material as discussed by the authors.
Abstract: Rhinocoris fuscipes Fabr, starts laying maroon coloured elongate eggs in batches at the age of 28-3 days. Eggs are glued to each other and to the substratum with cementing material. Eggs hatch in eight days, Nymphs are orange red with yellowish green legs bearing brown spots which simulate panther's skin. Stadial period from first instar to adult ranges from 38-50 days. Adult females live longer than the males. Out of two generations raised in the laboratory males and females emerge in the sex ratio 1 : 2. R. fuscipes is found to be predating on pests of cotton and maize both in the field and laboratory conditions.

TL;DR: In this paper, necessary and sufficient conditions for pointwise completeness of linear delay systems are established and functional controllability for such systems is also studied, and the relation between pointwise completeness and controllable to the origin is obtained.
