Abstract:

Securitatea spaţiului aerian este reglementată, la nivelul fiecărui stat, conform tratatelor și convențiilor internaționale, în toate situațiile posibile, pe timp de pace, de criză sau de război, prin integrarea tuturor sistemelor civile și militare de control al traficului aerian. Preocuparea până la nivel de îngrijorare a specialiștilor în sfera securității spațiului aerian reprezintă realitatea mediului operațional complex al operațiilor forțelor terestre. În acest context, pe fondul tehnologizării spațiului aerian și extinderii acțiunilor aeriene la diferite înălțimi, este justificată nevoia de conceptualizare operațională a sistemelor antiaeriene. Pentru aceasta, am redefinit spațiul aerian de responsabilitate al forțelor terestre, din perspectiva a două direcții de cercetare: amenințarea și agresiunea unui ipotetic inamic aerian; realizarea ripostei antiaeriene la diferite înălțimi. În cadrul acestui articol, am dezvoltat mai multe direcții de analiză și de conceptualizare a posibilităților de integrare a sistemelor de rachete antiaeriene VSHORAD, SHORAD și a sistemelor de arme antiaeriene cu rază de acțiune medie și lungă[i]. Prin acest demers științific, apreciez deschiderea unor noi serii de posibilități în proiectarea luptei cu inamicul aerian și de configurare probabilistică, pe noțiunea de eveniment, a ripostei antiaeriene, într-o manieră corespunzătoare noilor provocări din spațiul aerian actual.

Abstract:

Abstract It is assumed that special structures in aerial roots of leafless orchids, aeration units, are involved in gas exchange regulation. In this study, the structure of aeration units in three leafless taxa (Microcoelia exilis, M. aphylla, Dendrophylax funalis) and a leaf-bearing species (Campylocentrum micranthum) are investigated to obtain more evidence of a possible mechanism for gas exchange control in aerial orchid roots. Extensive analyses of the anatomy of the velamen radicum, exodermis and cortex were performed using light and electron microscopy and µCT. In all considered leafless taxa, the aeration unit consists of pneumathodes (non-wettable regions in the velamen radicum), an exodermal aeration cell (EAC) with a thin cell wall (often equipped with a special internal layer showing a fluffy structure) and specialized cortical cells (SCC). The SCC provide gaps for gas exchange, show differentially thickened cell walls and are arranged in a staggered manner. Based on the 3D structure of the aeration unit, we suggest the possibility of dehydration-triggered gap closure (driven by root shrinkage), in the process of which first the SCC are pushed against each other and second the EAC are squeezed shut by the exodermis.

Abstract:

While deammonification of high-strength wastewater in the sludge line of sewage treatment plants has become well established, the potential cost savings spur the development of this technology for mainstream applications. This study aimed at identifying the effect of aeration and organic carbon on the deammonification process. Two 10 L sequencing bath reactors with different aeration frequencies were operated at 25°C. Real wastewater effluents from chemically enhanced primary treatment and high-rate activated sludge process were fed into the reactors with biodegradable chemical oxygen demand/nitrogen (bCOD/N) of 2.0 and 0.6, respectively. It was found that shorter aerobic solids retention time (SRT) and higher aeration frequency gave more advantages for aerobic ammonium-oxidizing bacteria (AerAOB) than nitrite oxidizing bacteria (NOB) in the system. From the kinetics study, it is shown that the affinity for oxygen is higher for NOB than for AerAOB, and higher dissolved oxygen set-point could decrease the affinity of both AerAOB and NOB communities. After 514 days of operation, it was concluded that lower organic carbon levels enhanced the activity of anoxic ammonium-oxidizing bacteria (AnAOB) over denitrifiers. As a result, the contribution of AnAOB to nitrogen removal increased from 40 to 70%. Overall, a reasonably good total removal efficiency of 66% was reached under a low bCOD/N ratio of 2.0 after adaptation.

Abstract:

The soil aeration and hydric shortage greatly influence oil palm yield in Central America. This assay was conducted to identify and quantify the effect of the physical properties of the soil and rainfall on the yield of oil palm orchards in Coto and Quepos (Costa Rica) and San Alejo (Honduras). The following soil characteristics were evaluated: texture, moisture retention (pF), gravimetric moisture, drain water, total porosity, aerial space, large pore percentage, penetration resistance and tensimeter readings. These evaluations were conducted on 20 fruit bearing plots (in each locality) located within representative soil units; classified as: a) well drained (Fluventic Eutropepts), b) inperfect or moderately drained (Fluvaquentic Eutropepts) and c) poorly drained (Tropaquepts). San Alejo also shows soils with low base saturation (Dystropepts and Psamments). Twenty four additional plots were analyzed in this latter orchard to relate their yield with the catographic units. Regression and corre lation analysis were run for the three localities. The main limiting factors on production were: poor soil aeration en Coto, poor soil aeration and hydric shortage en Quepos, and poor aeration, low base saturation and sandy textures in San Alejo.

Abstract:

Cowpea, a short-cycle legume with large production in the North and Northeast regions, has its productive potential limited by edaphic characteristics and degradation processes of soil physical quality, such as compaction. This process may interfere with plant development and productivity by restricting root system growth, aeration, water and nutrient availability. The objective of this work was to analyze the interference of different levels of compaction in the soil physical characteristics, root growth, development of the aerial part and productivity of cowpea. The experiment was conducted in a greenhouse following a completely randomized design with a control (control) and four levels of soil compaction, with four replications. Each experimental unit was composed of PVC tubes composed of a 0.05-m layer of gravel, cotton fabric and a 0.04-m layer of soil. The different levels of compaction were obtained using a proctor socket and a wooden base. Based on the value of penetration resistance (PR) of 1.00 MPa, soil reached the macroporosity considered as critical theresohold for soil aeration. Results indicate that the higher the PR of the soil, the lower the development of the root system and the aerial part. The productive aspects of cowpea presented better results in plants grown in soils with a level of resistance to penetration close to 0.8 MPa.

Abstract:

Following inoculation onto seeds, the rhizobacterium Pseudomonas aureofaciens Ps3732RNL11 (L11), which contains the constituitively expressed lacZ and lacY genes from Escherichia coli, was recovered from the interior of aerial tissues of all 16 monocot and dicot plants tested, and the exterior of aerial surfaces of 15. In more detailed studies with corn, wheat, and broccoli, both Ps3732RNL11 and its nonengineered parent strain PS3732RN (RN) rapidly established large populations on all root systems and smaller densities within the aerial tissues, all of which persisted at stable levels throughout 12- to 23-day test periods. There were no differences in the behavior of L11 and RN on any of the three plant species. L11 invaded the aeriel tissues of corn in at least two distinct ways. First, it moved into the interior of leaves following inoculation of guttation drops, suggesting that the bacteria may contaminate the developing shoot prior to its emergence from the soil and then invade through natural openings. However, when this route was blocked by inoculating the roots after shoot emergence in either soil or hydroponic systems, the bacteria still invaded the aerial tissues within 24 h, suggesting direct vascular transport from the roots. Such bacterial movement is an important consideration in future field releases of both native and genetically modified rhizobacteria.Key words: rhizosphere, genetically engineered microorganism, Pseudomonas aureofaciens.

Abstract:

This project explored the feasibility of using video images acquired with an unmanned aerial vehicle (UAV) to obtain three-dimensional (3D) point clouds using structure from motion (SfM) software. Missions were flown using an Aeryon Scout: a lightweight, vertical take-off and landing quadrotor micro UAV with a miniature video camera. The initial mission captured urban scene images that were used to assess system performance while the main mission focused on rock walls where 3D images were used to successfully measure fracture orientations. Point clouds generated from this combination of technologies were sparse, but in the future, improvements in the resolution of original video images would cascade through the processing and improve the overall results. Such a system could have a multitude of applications in the mining industry, contributing to both safety and financial considerations.

Abstract:

ABSTRACT We use asexual development of Neurospora crassa as a model system with which to determine the causes of cell differentiation. Air exposure of a mycelial mat induces hyphal adhesion, and adherent hyphae grow aerial hyphae that, in turn, form conidia. Previous work indicated the development of a hyperoxidant state at the start of these morphogenetic transitions and a large increase in catalase activity during conidiation. Catalase 3 (CAT-3) increases at the end of exponential growth and is induced by different stress conditions. Here we analyzed the effects of cat-3-null strains on growth and asexual development. The lack of CAT-3 was not compensated by other catalases, even under oxidative stress conditions, and cat-3RIP colonies were sensitive to H2O2, indicating that wild-type (Wt) resistance to external H2O2 was due to CAT-3. cat-3RIP colonies grown in the dark produced high levels of carotenes as a consequence of oxidative stress. Light exacerbated oxidative stress and further increased carotene synthesis. In the cat-3RIP mutant strain, increased aeration in liquid cultures led to increased hyphal adhesion and protein oxidation. Compared to the Wt, the cat-3RIP mutant strain produced six times more aerial hyphae and conidia in air-exposed mycelial mats, as a result of longer and more densely packed aerial hyphae. Protein oxidation in colonies was threefold higher and showed more aerial hyphae and conidia in mutant strains than did the Wt. Results indicate that oxidative stress due to lack of CAT-3 induces carotene synthesis, hyphal adhesion, and more aerial hyphae and conidia.

Abstract:

Fully aerated surface cultures of Penicillium cyclopium and P. velutinum grown on liquid medium with 2-oxoglutarate or glutamate (34 mM) produced ethylene in association with the formation of aerial hyphae at about the 5th day (ethylene peak EP 1), its concentration then declined, and rose again during conidiation at about the 7th day (peak EP 2). In P. cyclopium glucose (22.2 mM) shortened differentiation, EP 1 and EP 2 merged, and culture pH dropped to 1.8. Methionine (34 mM) prevented the formation of aerial mycelium in P. cyclopium and penicilli initiation in P. velutinum; ethylene production was low. Under conditions of delayed aeration, P. cyclopium grown on glucose produced no ethylene and weak formation of immature conidia was observed. On other substrates both conidiation and ethylene production occurred after reaeration, but phase EP 1 was lacking. Penicillium velutinum grown on 2-oxoglutarate and glutamate with delayed aeration developed immature conidia within 36 h and traces of ethylene were produced. In the cultures with methionine and glucose, conidiation and ethylene production occurred after reaeration, but phase EP 1 was missing. In both strains, no ethylene was formed under anaerobic conditions. Intensively producing cultures were characterized by a narrow range of respiration yields (6.8–7.5 g dry weight per mole of consumed O2). A prerequisite for high ethylene production was a drop in the phosphate content of the medium to less than 0.45 mM.Key words: Penicillium cyclopium, Penicillium velutinum, ethylene, conidiation.

Abstract:

ABSTRACT Aerobic ammonium-oxidizing bacteria (AerAOB) and anoxic ammonium-oxidizing bacteria (AnAOB) cooperate in partial nitritation/anammox systems to remove ammonium from wastewater. In this process, large granular microbial aggregates enhance the performance, but little is known about granulation so far. In this study, three suspended-growth oxygen-limited autotrophic nitrification-denitrification (OLAND) reactors with different inoculation and operation (mixing and aeration) conditions, designated reactors A, B, and C, were used. The test objectives were (i) to quantify the AerAOB and AnAOB abundance and the activity balance for the different aggregate sizes and (ii) to relate aggregate morphology, size distribution, and architecture putatively to the inoculation and operation of the three reactors. A nitrite accumulation rate ratio (NARR) was defined as the net aerobic nitrite production rate divided by the anoxic nitrite consumption rate. The smallest reactor A, B, and C aggregates were nitrite sources (NARR, >1.7). Large reactor A and C aggregates were granules capable of autonomous nitrogen removal (NARR, 0.6 to 1.1) with internal AnAOB zones surrounded by an AerAOB rim. Around 50% of the autotrophic space in these granules consisted of AerAOB- and AnAOB-specific extracellular polymeric substances. Large reactor B aggregates were thin film-like nitrite sinks (NARR, <0.5) in which AnAOB were not shielded by an AerAOB layer. Voids and channels occupied 13 to 17% of the anoxic zone of AnAOB-rich aggregates (reactors B and C). The hypothesized granulation pathways include granule replication by division and budding and are driven by growth and/or decay based on species-specific physiology and by hydrodynamic shear and mixing.

Abstract:

Photogrammctric mapping methods (Dueholm, 1979; Jepsen & Dueholm, 1978; Pedersen, 1981) are widely used by the Geological Survey of Greenland (GGU). However, until now it has only been possible to use vertical aerial photographs taken with large frame photogrammetric cameras. As a major part af the geology in Greenland is exposed on steep mountain sides. there are many afcas that e(]llllot be rnappcd from vertical aerial pl1otographs. In 1983 a research projccl was set up to invcstigate phologrammetric mapping using commerci ally available oblique aeria! photographs, as well as terrestriaJ photographs taken by geologists with ordinary 24/36 mm cameras (fig. 1). A new type of photogrammetric instrument, the Kern DSR11/GP1 AnalyticaI Plotter, was procured for this and other projects. Here we present results and experience from the first successful mapping in Greenland with an ordinary 24/36 mm camera.

Full text

Abstract:

Surface cultures of Penicillium cyclopium, grown in a closed aeration system on a semisolid minimal medium with 2-keto-glutarate, glutamate or glucose as carbon source, produced ethylene in two phases. The first was associated with aerial hyphae formation; the second, with conidiation. The maximum rate of ethylene synthesis coincided with intensive oxygen consumption whereas the cessation and reutilization of ethylene occurred together with a low respiration rate. After the removal of the aerial mycelium, vegetative hyphae continued ethylene production up to 50% of the value reached in intact cultures. Neither detached aerial mycelium with penicilli nor pure conidia produced ethylene. The content of ethylene in the medium of a producing culture was four-fold higher than would correspond to its concentration in the atmosphere above the culture. In the upper agar layer (1.25 mm), a high pH (8.8) and 30 mM [Formula: see text]was found, presumably because of mycelium autolysis. The pH in the layer 3 mm below the surface was 2.4. In lower layers (up to 2 mm beneath the last vegetative hyphae), ammonium ions were completely depleted. The phosphate content was inversely proportional to the hyphal density. We suggest that the low phosphate concentration (0.06 mM) in the upper layers permitted ethylene formation.Key words: conidiation, vegetative hyphae, ethylene, ion gradients, surface culture.

Abstract:

Beauveria bassiana is an entomopathogenic fungus that is used for the biological control of different agricultural pest insects. B. bassiana is traditionally cultivated in submerged fermentation and solid-state fermentation systems to obtain secondary metabolites with antifungal activity and infective spores. This work presents the design and characterization of a new laboratory-scale biofilm bioreactor for the simultaneous production of oosporein and aerial conidia by B. bassiana PQ2. The reactor was built with materials available in a conventional laboratory. KLa was determined at different air flows (1.5–2.5 L/min) by two different methods in the liquid phase and in the exhaust gases. The obtained values showed that an air flow of 2.5 L/min is sufficient to ensure adequate aeration to produce aerial conidia and secondary metabolites by B. bassiana. Under the conditions studied, a concentration of 183 mg oosporein per liter and 1.24 × 109 spores per gram of support was obtained at 168 h of culture. These results indicate that the biofilm bioreactor represents a viable alternative for the production of products for biological control from B. bassiana.

Abstract:

The research concerns the methods of UAV group control in networks with duplex communication between nodes built on the "client-server" architecture. Such systems belong to self-organized networks with variable topology. It is important to study the allowable parameters of deviation from the task in the management of a group of UAVs and analysis of the network topology for the group flighting. The network was optimized according to the Ant Colony algorithm ACO. The application of different types of algorithms prevents routing problems in networks, such as ANTMANET, AntNet, ACODV and others. Methods of coordination of group joint actions are considered. A method is proposed by which the optimal number of UAVs operated by one operator can be determined and the traffic intensity of the communication channel is calculated, as well as the bandwidth and packet transmission delay are estimated.

In the pH-stat syntheses, the desautelsite is formed by aerial oxidation of MnCO3in 0·05–0·15mMg(NO3)2solutions at ∼pH 9 and temperatures of 35°C where, in the absence of Mg, manganite would normally form. The synthesis product from this technique is generally more crystalline than that formed by the coprecipitation method. Composition, particle shape and aggregation may be controlled through variations of the Mg concentration, pH, aeration rate or temperature. Indirect evidence suggests Mn to be present in the +3 oxidation state in the desautelsite.
