The species is named after the country where it was collected and in honour of Dr. Rida Y. Nuwayhid, the Lebanese scientist at the Engineering Department, The American University of Beirut who guided us to the galls. Diagnosis.

Body length 2.8–4.1 mm. Gall (Figs 131–134). On lateral and terminal shoot buds, on both young and old trees. The gall is similar to that induced by A. coriarius, in that it is usually globular-slightly flattened, contains many larval chambers, and is coated in spines. However, in contrast to A. coriarius (see description in A. coriariformis above), the spines on A. libani are usually very short (often less than 5 mm in length), blunt and often recurved. The gall is also usually somewhat smaller than A. coriarius, usually with a maximum diameter of 20 mm. Biology. Only the asexual generation is known from galls on Quercus infectoria Olivier. Rare. Comments. This species was initially detected on the basis of DNA sequence data for the mitochondrial cytochrome b gene and the nuclear 28S D2 region (Challis et al. 2007). Although originally identified as Andricus coriarius on the basis of overall gall morphology, all adults with the above described phenotype belong to a single well-resolved clade that is inferred to have diverged from A. coriarius almost 9 million years ago. Existing sequence data suggest that A. libani is not closely related to A. coriarius, and not a member of the A. kollari species group (Challis et al. 2007). The extreme rarity of purely asexual lifecycles in oak gallwasps (Stone et al. 2002) suggests that A. libani p robably has a sexual generation. The clade of Andricus species that includes A. libani all have lifecycles involving alternation between oaks in the sections Quercus (for the asexual generation) and Cerris (for the sexual generation). The sexual generation galls in this clade are commonly small and inconspicuous bud or catkin galls (Melika, Csóka & Pujade-Villar 2000; Cook et al. 2002; Rokas et al. 2003b), and it is probable that the same is true for this new species. Possible hosts from the Cerris oak section in the region include Quercus libani Olivier and Q. brantii Lindl. (= Q. persica Jaub. et Spach). Distribution.

Body length 4.5– 5.0 mm (holotype female 4.7 mm). Gall (Figs 29–34). The gall develops at the base of the acorn cup and may cover the stunted acorn. The gall has an extremely irregular shape; it may be globular around the acorn, or extend into broad, pointed radiating spines. The diagnostic feature of the gall is its surface texture, which is always smooth, polished and covered in a sticky resin. Mature galls contain a small air space around a distinct thin-walled larval chamber. Across its spines, the gall is 15–55 mm high and 15–35 mm across. The gall is yellow when young, turning pale to reddish brown when mature. The gall of A. dentimitratus closely resembles that of A. assarehi, however, the later with much longer radiating irregular spines and the shape and form of the gall is more irregular, strongly varying. Biology. Only an asexual generation is known from galls on Quercus infectoria Olivier. Galls appear on the tree by mid-summer; adult wasps emerge in November-December. The galls remains on the tree for one year. Rare species. Comments. The extreme rarity of purely asexual lifecycles in oak gallwasps (Stone et al. 2002) suggests that A. assarehi p robably has a sexual generation. The clade of Andricus species that includes A. assarehi all have lifecycles involving alternation between oaks in the sections Quercus (for the asexual generation) and Cerris (for the sexual generation). The sexual generation galls in this clade are commonly small and inconspicuous bud or catkin galls (Melika, Csóka & Pujade-Villar 2000; Cook et al. 2002; Rokas et al. 2003b), and it is probable that the same is true for this new species. Possible hosts from the Cerris oak section in the region include Quercus libani Olivier and Q. brantii Lindl. (= Q. persica Jaub. et Spach). Distribution. Iran, Kordestan province (Bane).

Gall (Figs 14–17). An integral leaf gall, develops on both sides of the leaf (usually on terminal leaves of the twig), 10–20 mm long, irregularly shaped; multilocular, containing many cells. Young galls are fleshy and pale green to yellowish, and become brown and remain soft as they mature. Galls usually occur gregariously, resulting in a noticeable deformation of the leaf. Biology. Only the sexual generation is known from galls on Quercus brantii Lindl. Young galls become apparent from the beginning of May; adult wasps emerge from mid-May. Rare species. Distribution. Iran, Lorestan (Ghelaei) and Kermanshah provinces (Pave).

thin films, possessing potential for MIS electronic applications, have been deposited on clean Si and InP surfaces by evaporating powder from a graphite cell heated by electron bombardment. The build up of the films was monitored by Auger electron spectroscopy (AES). Continuous, amorphous films were also prepared on microgrids, for TEM studies. The film thickness was measured using multiple angle of incidence (66 - ) and angle ellipsometry using a 633 nm laser line. Calibration curves have been calculated for n = 1.61 - 1.77 limits for and various substrates. They were considerably affected by the substrate optical constants. Evaluation of ellipsometric data resulted in typical thickness values of 5 - 10 nm as confirmed with cross-sectional TEM.

We investigated the effect of 0.65 MeV electron irradiation on the transport parameters of GaAs FATFETs with an S-doped active channel of thickness 0.2 μm to 5 μm. We measured mainly the drift mobility and carrier concentration profile at severall temperatures from 170 K to 300 K before and after irradiation. A decrease of the mobility is observed of the mobility profiles as a function of temperature by introduction of different scattering mechanisms gives the scattering parameters and particularly the scattering rate by ionized impurities and space charge before and after irradiation. DLTS and DLOES measurements indicated three electron traps and four hole traps. The results show that the two main electron traps E2 and E3 are affected by an intermediate donor type electronic state Tx The nature of Tx is not known, except that it behaves like a donor. © 1994 Akadémiai Kiadó.

Electron irradiation at room temperature introduces in GaAs a donor type electronic state Tx at 0.18 eV, which is associated with the E3 electron trap. The presence of Tx is observed at depths d > 1.5 microm, which correspond to the limits of the depletion region under the highest applied reverse bias voltage, while the E3 trap concentration drops off into the same region. © 1993.
