O papel do macaco-prego Sapajus nigritus na dispersão de sementes e no controle potencial de insetos-praga em cultivos agrícolas e florestais.

Os macacos-prego da especie Sapajus nigritus ocupam diferentes fitofisionomias da Floresta Atlântica do sudeste e sul do Brasil. Apresentam dieta omnivora, com ampla diversidade de itens alimentares, onde predominam frutos e insetos. Dessa forma, nos investigamos o papel deste primata como dispersor de sementes e como potencial controlador de pragas agricolas e florestais. As amostragens foram realizadas em remanescentes de Floresta Estacional Semidecidual (FES) cercados por cultivos agricolas e de Floresta Ombrofila Mista (FOM) entremeados a plantios florestais exoticos. Das 1.567 amostras fecais da especie coletadas em FES, 76% continham sementes intactas e 90% continham restos de artropodos, sendo 96% insetos. Ja nas 7.270 amostras coletadas na FOM, as sementes estavam presentes em 28% das amostras e os artropodos em 71% delas. No geral, os macacos-prego dispersaram sementes de 118 especies florestais e consumiram insetos de seis ordens diferentes, sendo que os hemipteros da familia Pentatomidae estavam presentes em 75% das amostras da FES. Considerando a necessidade de manutencao e, principalmente, de restauracao da Floresta Atlântica e o fato de varios insetos causarem danos aos plantios agricolas e florestais, discute-se o papel de Sapajus nigritus como dispersor de sementes florestais e auxiliar no controle de insetos-praga, servico ambiental raramente reconhecido para a especie.
Fluid Dynamic Assembly of Semiconductor Blocks for Heterogeneous Integration

We have studied the fluidic assembly (FA) technique for heterogeneous integration. In this technique, device blocks, the size of which ranges from a few tens of microns to a few hundreds of microns, are arranged onto another material substrate in fluid. Here, we propose a novel technique to improve FA, called fluid dynamic assembly (FDA), which employs fluid dynamic effects. In the FDA, a special structure is fabricated on the block, which stabilizes the posture of the blocks falling in the fluid. This can be used to control the face of assembled blocks. In this paper, the feasibility of the FDA is discussed on the basis of fluid dynamic simulation and experiments. The numerical simulations revealed that the face control can be carried out for the block having ringlike (O-type) structures on it. Then we carried out the FDA experiments using thin disk-shaped GaAs blocks with O-type structure, and demonstrated an 87% face control ratio for the blocks with 7.5-µm-thick structure. Moreover, the less symmetric C-type structure was examined, and demonstrated even a high face control ratio of 96%.

The study was conducted from April, 2018 to June, 2018 in Humbo district of southern Ethiopia to determine current infection rate of bovine trypanosomosis, to identify trypanosome species responsible for infection, to assess potential risk factors of the disease, and to evaluate the relationship between infection rate and packed cell volume. Blood samples were collected from 306 randomly selected cattle from the study peasant associations (PAs) and evaluated through conventional parasitological methods.
Improved genetic algorithm for resource-constrained scheduling of large projects

The generalized model of the resource-constrained project scheduling problem (RCPSP) is valuable because it can be incorporated into the advanced computational methods of commercial project management software for practical applications. A construction schedule generated by most commercial project management programs does not guarantee its optimality when the resources are limited. This paper presents an improved elitist genetic algorithm (GA) for resource-constrained scheduling of large projects. The proposed algorithm allocates multiple renewable resources to activities of a single large-sized project to achieve the objective of minimizing the project duration. A permutation-based decoding procedure is developed using the improved parallel schedule generation scheme. A new parameter, named transformation power, is created in the transformation method of the improved algorithm to ensure that the individual selection process performs correctly. Extensive computational results using a standard set of large.
Application of GLEAMS to predict nutrient losses from land application of poultry litter

The GLEAMS (Groundwater Loading Effects of Agricultural Management System) (version 2.1) water quality model was used to predict nutrient (N and P) losses in surface and subsurface runoff, and their concentrations in soil layers, following application of two rates (9 and 18 t ha–1) of poultry litter and a recommended rate of a commercial fertilizer on conventionally tilled corn plots at the Tennessee Valley Substation of the Alabama Agricultural Experiment Station. Model simulation results were compared with field data. The experiment included four replications for each of the three soil-amendment treatments. The GLEAMS simulation of soluble and sediment P losses in surface runoff and NO3-N concentrations in leachate and soil layers were not consistent with field data. Simulation of N-transformation effects on N losses in surface runoff did not agree with field data. The model simulated higher NH4-N than NO3-N losses in surface runoff, while field data showed the opposite. The model simulated low concentrations of P in leachate at a 1.0 m depth, while the observed data showed large variations.

Optimal design of phase change random access memory based on 130nm CMOS technology

An 8Mb phase change random access memory (PCRAM) has been developed by a 130nm 4-ML standard CMOS technology based on the Resistor-on-Via-stacked-Plug (RVP) storage cell structure. This phase change resistor is formed after CMOS logic fabrication. PCRAM can be embedded without changing any logic device and process. The memory cell selector is implemented by a standard 1.2V NMOS device. Aimed at the resistance distributions, lowering the operation current and improving the bit yield, some methods are used to optimize the design of the chip.

An Investigation of Refrigerant Void Fraction in Horizontal, Microfin Tubes

A series of experiments to determine void fraction in both condensation and evaporation have been performed in horizontal microfin tubes with refrigerants R134a and R410A. Mass flux varied from 75 kg/m2·s to 700 kg/m2·s and average test section quality varied from 5% to 80%. Zero degree (axial grooving) and 18 degree helix microfin tube configurations have been examined in both condensation and evaporation. Four tubes were examined (7.3 mm and 8.9 mm diameters with axial and 18 degree helix angle microfins). Evaporation and adiabatic conditions in microfin tubes generally show similar void fraction trends found in smooth tubes. Condensation results for microfin tubes show a lower void fraction than smooth tubes.
A TaOx-Based RRAM with Improved Uniformity and Excellent Analog Characteristics by Local Dopant Engineering

Resistive random-access memory (RRAM) with the ability to store and process information has been considered to be one of the most promising emerging devices to emulate synaptic behavior and accelerate the computation of intelligent algorithms. However, variation and limited resistance levels impede RRAM as a synapse for weight storage in neural network mapping. In this work, we investigate a TaOx-based RRAM with Al ion local doping. Compared with a device without doping, the device with locally doped Al ion exhibits excellent uniformity and analog characteristics. The operating voltage and resistance states show tighter distributions. Over 150 adjustable resistance states can be achieved through tuning compliance current (CC) and reset stop voltage. Moreover, incremental resistance switching is available under optimized identical pulses. The improved uniformity and analog characteristics can be attributed to the collective effects of reduced oxygen vacancy (Vo) formation energy and weak conductive filaments induced by the local Al ion dopants.
Residential photovoltaic systems in Greece and in other European countries: a comparison and an overview

One of the most promising renewable energy technologies (renewable energy sources, RESs) is photovoltaics (PVs). PVs are a truly elegant means of producing electricity on site, directly from the sun, without concern for energy supply or environmental harm. They represent a favorable case: easy and fast installation, low maintenance requirements and the ability to produce electricity on site within the urban built environment. In that sense, there is a growing consensus that PVs for individual buildings, known as building integrated or applied PVs (BIPVs or BAPVs, respectively), will be chief among the continuously widespread distributed PV applications. Still, they suffer from the disadvantage of their very high initial cost compared to other renewable and conventional energy technologies, although this has been steadily reduced during the last 5 years. It is therefore evident that without the support of suitable instruments, the expansion of solar electricity worldwide would not take place at a satisfactory pace. Various effective support mechanisms have been adopted, within which feed-in tariff (FiT) proved to be the most successful for PVs. That is the case also in Greece, where the PV market in the building sector grew rapidly after 2009, due to the great FiT incentives granted particularly for residential applications. In this paper an overview is provided, accompanied by a comparative feasibility study regarding residential PV systems’ prospects, based on the review of all kinds of incentive schemes in EU for small-scale BAPVs.
Wet Adhesive Properties of Asian Green Mussel ( Perna viridis ) Foot Protein Pvfp-5: An Underwater Adhesive Primer

: Asian green mussels ( Perna viridis ) are bivalves that attach firmly to rocks in wave-battered intertidal seashores via a proteinaceous secretion. P. viridis mussels follow a precisely time-regulated secretion of adhesive proteins where P. viridis foot protein-5 (Pvfp-5) was identified as the first protein to be secreted during the formation of adhesive plaque. The high content of catecholic amino acid 3,4-dihydroxy-L-phenylalanine (DOPA) (  11 mol%) and cysteine (Cys) (  15 mol%) in Pvfp-5 and its localization near the plaque-substrate interface have prompted speculation that the vanguard protein Pvfp-5 plays a key role as an adhesive primer in underwater adhesion of P. viridis mussels. Surface Force Apparatus (SFA) was used to probe the adhesive properties of Pvfp-5 at the nano-scale where pH dependent wet adhesion and antioxidant activity of foot-extracted and purified Pvfp-5 were investigated. The study revealed that Pvfp-5 with its high DOPA and CYS-content maintains adhesion even at higher pH by overcoming the spontaneous oxidation of DOPA to quinone. SFA results are consistent with the apparent function of Pvfp-5 acting as an adhesive primer, overcoming repulsive hydration forces by displacing surface-bound water and generating strong and durable surface adhesion. Our findings reveal molecular-scale insights that should prove relevant and impact material sciences to help the development of new generation of wet-resistant adhesives, coatings and glues for biomedical, therapeutic and

Die Gründungsdynamik in technologieorientierten Industrien: Eine Analyse der IAB-Beschäftigtenstatistik

During the last years more and more discussions came up about the contribution of technology-oriented and technology-intensive industries for the economic development and employment. One reason for these contradictory evaluations of technology-intensive industries can be attributed to different conceptual definitions of technology which are briefly discussed. The foundation and liquidation dynamic of West-Germany is examined for the period 1979-1992 on the basis of a data set from the employment statistics of the Federal Institute of Labour and the Institut fur Arbeitsmarkt- und Berufsforschung (lAB). The result is that there are great differences in the foundation and liquidation performance between technology-oriented, not technology-intensive and selected parts of the service sector. The effect of the economic development is analysed in the final part of the paper, showing that technology-oriented industries are more linked to the economic performance than other industries.

SABER: Selection of approximate bits for the design of error tolerant circuits

A wide variety of error tolerant applications supports the use of approximate circuits that achieve power savings by introducing small errors. This paper proposes a fast and novel algorithm for the design of such circuits with the goal of maximizing power savings, constrained by a fixed error budget, through an analytical expression to optimally select the number of bits to be approximated. This algorithm outperforms uniform approximation schemes by over 30% in power savings, with negligible computational overhead.

Clinical observation of short-term on primary pars plana vitrectomy without perfluorocarbon fluids under the wide-angle observation system in treatment rhegmatogenous retinal detachment with PVR ≦C2

Background: To observe the short-term efficacy of vitrectomy for wide-angle observation system without perfluorocarbon liquid (PFCL )in the treatment of rhegmatogenous retinal detachment(RRD) with Proliferative vitreous retinopathy (PVR ) ≦C2.Methods: Retrospective analysis of the case data of patients with rhegmatogenous retinal detachment who did not use or use perfluorocarbon liquid during vitrectomy, including age, sex, course of disease, PVR classification, preoperative and stepwise best corrected positive vision , Perfluorocarbon liquid in the perfluorocarbon liquid group, the reposition state of the retina, the difference in visual acuity recovery and retina reset rate within and between groups.Results: There was no statistically significant difference in baseline data (age, sex, course of disease, PVR grade) between the non-perfluorocarbon liquid group and the perfluorocarbon liquid group (P> 0.05). The rate of initial reset at the time of discharge from the non-perfluorocarbon liquid group was 92.9%. The retinal reposition rate at 6 months after surgery was 100%. The rate of initial reduction at discharge was 93.5% in the group using perfluorocarbon liquid, and the final retinal reduction rate at 6 months after surgery was 100%. There was no statistically significant difference in logMAR BCVA of postoperative follow-up time between the two groups (P> 0.05). Without the use of perfluorocarbon liquid, there was no postoperative perfluorocarbon liquid residue, and the residual rate of perfluorocarbon liquid in the perfluorocarbon liquid group was 14.5%. Conclusion: Vitrectomy without the use of perfluorocarbon fluids under the wide-angle observation system is the first choice to treat rhegmatogenous retinal detachment with PVR≤C2.
Impedance as guidance for electrode placement in intraoperative monitoring of nerve fibers

Electrodes for intraoperative monitoring should be reliable and should not disturb the surgeon. Since any wiring could complicate the handling of other medical instruments, new developments of autonomic, wireless electrodes are preferred. This new generation of electrodes will not only stimulate the nerve, but will monitor the action potentials as well. A failure to read nerve potentials may be indicative not just of damaged nerves, but may also result from bad electrode-nerve contact. To resolve this, we have developed electrodes which are equipped with impedance measurement features, facilitating simple connectivity checks. Due to energy constraints, the system works in the time domain using a rectangular voltage wave excitation. The voltage at the electrode is sampled and transmitted via RF link to the host computer. The frequency range covered by the excitation and sampling is between 100 Hz and 50 kHz, which is sufficient not only for detecting contact failure, but also for detecting thick layers of connective tissue between the electrode and the nerve fibre. In either instance, the surgeon can be warned of a bad electrode placement.
