    Abstract The relative short distance (∼165 pc) and considerable mass (≳2000M ⊙) of the Rho Ophiuchi cloud enable the study of the physical conditions within the cloud with a fine detail as it is reached in few complexes only. On the basis of the observations between 10−14 and 10−1 m wavelength, the most remarkable features of the cloud detected are: (1) The cloud represents one of the strongest detectable γ-ray sources for energies greater than 100 MeV. (2) X-ray observations gave no evidence that the cloud is interacting with a supernovae remnant or a neutron star what was supposed to account for the observed γ-ray flux. (3) Ultraviolet observations indicate that a considerable number of small particles is present toward the embedded star HD 147889 being placed at the edge of the cloud. (4) The ratio of total to selective extinction isR〉4 toward the denser regions of the cloud. (5) An embedded stellar cluster of about 50 stars was detected by four IR-surveys toward the central region of the cloud. (6) Far-IR observations indicate that there are only 3 B-stars within the cloud. The dust-temperature reaches locally 50 K. (7) More than 10 different molecular species were detected by ratio observations. A considerable depletion of heavy elements is observed. There are two dense regions within the cloud which are likely contracting.

    Abstract We have modeled the growth of an N-mer by means of Monte-Carlo calculations. The geometrical cross-section of the N-mer is measured and compared with the one obtained if one assumes that the N-mer is of spherical form. A difference up to a factor of 2 was found forN≤30.

    Abstract. Single-pulse excimer-laser irradiation of poly-ethylene-terephthalate (PET) with fluences around and above the ablation threshold leads to the formation of surface dendrites. The lateral size and the number density of dendrites depend on the laser wavelength and the type and pressure of the ambient atmosphere. The results are discussed on the basis of excimer-laser-induced polymer fragmentation and the redeposition of ablation products.

    Abstract  The impacts of crop rotations and N fertilization on different pools of arylsulfatase activity (total, intracellular, and extracellular) were studied in soils of two long-term field experiments in Iowa to assess the contibution of the microbial biomass to the activity of this enzyme. Surface-soil samples were taken in 1996 and 1997 in corn, soybeans, oats, or meadow (alfalfa) plots that received 0 or 180 kg N ha–1 before corn, and an annual application of 20 kg P ha–1 and 56 kg K ha–1. The arylsulfatase activity in the soils was assayed at optimal pH (acetate buffer, pH 5.8) before and after chloroform fumigation; microbial biomass C (Cmic) and N (Nmic) were determined by chloroform-fumigation methods. All pools of arylsulfatase activity in soils were significantly affected by crop rotation and plant cover at sampling time, but not by N fertilization. Generally, the highest total, intracellular, and extracellular arylsulfatase activities were obtained in soils under cereal-meadow rotations, taken under oats or meadow, and the lowest under continuous cropping systems.Total, intracellular, and extracellular arylsulfatase activities were significantly correlated with Cmic (r〉0.41, P〈0.01) and Nmic (r〉0.38, P〈0.01) in soils. The averages of specific activity values, i.e., of arylsulfatase activity of the microbial biomass, expressed per milligram Cmic, ranged from 315 to 407 μg p-nitrophenol h–1. The total arylsulfatase activity was significantly correlated with the intracellular activity, with r values 〉0.79 (P〈0.001). In general, about 45% of the total arylsulfatase activity was extracellular, and 55% was associated with the microbial biomass in soils, indicating the importance of the microflora as an enzyme source in soils.

    Abstract  The impacts of crop rotations and N fertilization on different pools of urease activity were studied in soils of two long-term field experiments in Iowa; at the Northeast Research Center (NERC) and the Clarion-Webster Research Center (CWRC). Surface soil samples (0–15 cm) were taken in 1996 and 1997 in corn, soybeans, oats, or meadow (alfalfa) plots that received 0 or 180 kg N ha–1, applied as urea before corn and an annual application of 20 kg P and 56 kg K ha–1. The urease activity in the soils was assayed at optimal pH (THAM buffer, pH 9.0), with and without toluene treatment, in a chloroform-fumigated sample and its nonfumigated counterpart. The microbial biomass C (Cmic) and N (Nmic) were determined by chloroform fumigation methods. The total, intracellular, extracellular and specific urease activities in the soils of the NERC site were significantly affected by crop rotation, but not by N fertilization. Generally, the highest total urease activities were obtained in soils under 4-year oats–meadow rotations and the lowest under continuous corn. The higher total activities under multicropping systems were caused by a higher activity of both the intracellular and extracellular urease fractions. In contrast, the highest values for the specific urease activity, i.e. of urease activity of the microbial biomass, were found in soils under continuous soybean and the least under the 4-year rotations. Total and extracellular urease activities were significantly correlated with Cmic (r〉0.30* and 〉0.40**) and Nmic (r〉0.39** and 〉0.44**) in soils of the NERC and CWRC sites, respectively. Total urease activity was significantly correlated with the intracellular activity (r〉0.73***). About 46% of the total urease activity of the soils was associated with the microbial biomass, and 54% was extracellular in nature.

    Abstract  The impacts of crop rotations and N fertilization on microbial biomass C (Cmic) and N (Nmic) were studied in soils of two long-term field experiments initiated in 1978 at the Northeast Research Center (NERC) and in 1954 at the Clarion-Webster Research Center (CWRC), both in Iowa. Surface soil samples were taken in 1996 and 1997 from plots of corn (Zea mays L.), soybeans (Glycine max (L.) Merr.), oats (Avena sativa L.), or meadow (alfalfa) (Medicago sativa L.) that had received 0 or 180 kg N ha–1 before corn and an annual application of 20 kg P and 56 kg K ha–1. The Cmic and Nmic values were determined by the chloroform-fumigation-extraction method and the chloroform-fumigation-incubation method, respectively. The Cmic and Nmic values were significantly affected (P〈0.05) by crop rotation and plant cover at time of sampling, but not by N fertilization. In general, the highest Cmic and Nmic contents were found in the multicropping systems (4-year rotations) taken in oats or meadow plots, and the lowest values were found in continuous corn and soybean systems. On average, Cmic made up about 1.0% of the organic C (Corg), and Nmic contributed about 2.4% of the total N (Ntot) in soils at both sites and years of sampling. The Cmic values were significantly correlated with Corg contents (r≥0.41**), whereas the relationship between Cmic and Ntot was significant (r≤0.53***) only for the samples taken in 1996 at the NERC site. The Cmic : Nmic ratios were, on average, 4.3 and 6.4 in 1996, and 7.6 and 11.4 in 1997 at the NERC and CWRC sites, respectively. Crop rotation significantly (P〈0.05) affected this ratio only at the NERC site, and N fertilization showed no effect at either site. In general, multicropping systems resulted in greater Cmic : Corg (1.1%) and Nmic : Ntot (2.6%) ratios than monocropping systems (0.8% and 2.1%, respectively).

    Abstract We consider homogeneous particles with a frequency-dependent index of refractionn =n′ +in″ = 1 +β(ω), ∣β(ω)∣≪1, in an outer electromagnetic field. From general considerations we derive an expression for the total scattering cross-section of these particles. We calculate the efficiency factor for the sphere, the infinite circular cylinder, and for an ellipsoidal particle with the main axesa=1,b=2,c=1. In contrast with the ray approximation, the present method can be used to calculate the polarization of the scattered light from ellipsoids.

    Zusammenfassung Die minimalinvasive Chirurgie der Nebenniere ist sowohl laparoskopisch-transperitoneal als auch endoskopisch-extraperitoneal sicher und mit geringer Morbidität durchführbar. Erste vergleichende Darstellungen mit konventionell operierten Patienten belegen die Vorzüge der minimalinvasiven Technik. Gegenüber der endoskopischen retroperitonealen Adrenalektomie bietet das laparoskopisch-anteriore Vorgehen den Vorteil der übersichtlicheren Exposition unter Orientierung an anatomischen Leitstrukturen sowie die Möglichkeit von laparoskopischen Synchroneingriffen. Anhand 2er Fallberichte wird die von uns angewandte transperitoneale Operationstechnik zur synchronen bilateralen laparoskopischen Adrenalektomie wegen eines beidseitigen Phäochromozytoms beschrieben. Die Operationszeiten betrugen 210 bzw. 270 min, der intraoperative Blutverlust lag bei 350 bzw. 400 ml. Postoperative Komplikationen traten nicht auf, eine vollständige körperliche Mobilität war bereits am 1. postoperativen Tag gegeben. Immunologische Untersuchungen belegen die geringe Invasivität des Eingriffs.
    Notes:
    Abstract Laparoscopic transperitoneal and endoscopic extraperitoneal adrenalectomy are two safe options in minimally invasive surgery associated with a very low morbidity. Comparative studies with the conventional access to the adrenal gland demonstrated the advantages of the endoscopic technique. The anterior transperitoneal approach yields a better exposure of the anatomic structures and allows the surgeon to orient himself more easily, while at the same time he may perform additional laparoscopic maneuvers. In two cases of bilateral pheochromocytoma a bilateral laparoscopic adrenalectomy was performed simultaneously by employing the transperitoneal approach. The duration of surgery was approximately 210 and 270 min, respectively, with an intraoperative blood loss of about 350 and 400 ml. There were no complications following this procedure. Already on the 1st postoperative day, the patients could be fully mobilized. Furthermore, immunological data obtained perioperatively support the minimal invasiveness of this technique.

    Abstract: We apply quantum and semiclassical theories to differential optical collisions Na(32S1/2) + Kr + Na(32P1/2,3/2) + Kr. Our results provide a basis to analyze recent experiments in which for the first time optical collisions were investigated with angular resolution under crossed-beam conditions. A characteristic feature of the differential cross sections is the pronounced oscillatory structure due to interferences of different Condon paths. These Stueckelberg oscillations form an extremely sensitive probe of the collisional dynamics and of the molecular interactions. We demonstrate perspectives to determine geometric properties of the collision complex by excitation with polarized light. By final state analysis nonadiabatic (spin-orbit, rotational) interactions can be studied with complete control of the path. In summary it is shown that the method of differential detection of optical collisions opens a variety of new accesses to atomic and molecular subcollisions.
