Abstract:

Conventional methods of processing hollow silica granules are tedious, expensive and time consuming. The present work aims at the production of hollow silica granules by a rapid, simple & cost-effective process, by employing microwave heat treatment which reduces the time factor drastically. Microwave processing is an emerging field and is fast catching up as an excellent alternative to the electrical heating methods. Spherical hollow silica granules with in-situ fibrous network were obtained by firing the sol-gel derived silica gel in a microwave furnace. Sol was synthesized using TEOS, distilled water, HCl & Ethanol and was allowed to age in a wide tray at ambient temperature & pressure. The ageing time of the gel was varied from 1-80 days and the characteristics of the granules hence obtained were studied. The temperature of heat treatment was also varied and it was observed that spherical granules form in the temperature range of 1250-1400°C. For comparison, the same gel was heat treated in a conventional furnace and the characteristics of the granules hence obtained were also studied. It was observed that conventionally sintered granules were less dense than the microwave derived ones but were not hollow. This paper describes the processing of hollow silica granules and the effect of gel ageing duration and temperature of sintering on the final product obtained.

Abstract:

Sound or noise pollution has become one major issues to the community especially those who lived in the urban areas. It does affect the activity of human life. This excessive noise is mainly caused by machines, traffic, motor vehicles and also any unwanted sounds that coming from outside and even from the inside of the building. Such as a loud music. Therefore, the installation of sound absorption panel is one way to reduce the noise pollution inside a building. The selected material must be a porous and hollow in order to absorb high frequency sound. This study was conducted to evaluate the potential of egg tray and coir fibre as a sound absorption panel. The coir fibre has a good coefficient value which make it suitable as a sound absorption material and can replace the traditional material; syntactic and wooden material. The combination of pyramid shape of egg tray can provide a large surface for uniform sound reflection. This study was conducted by using a panel with size 1 m x 1 m with a thickness of 6 mm. This panel consist of egg tray layer, coir fibre layer and a fabric as a wrapping for the aesthetic value. Room reverberation test has been carried to find the loss of reverberation time (RT). Result shows that, a reverberation time reading is on low frequency, which is 125 Hz to 1600 Hz. Within these frequencies, this panel can shorten the reverberation time of 5.63s to 3.60s. Hence, from this study, it can be concluded that the selected materials have the potential as a good sound absorption panel. The comparison is made with the previous research that used egg tray and kapok as a sound absorption panel.

Abstract:

Manual rectangle pipe-jacking technology is adopted to jack the pre-fabricated hollow box girder slowly and evenly into the load bearing wall of masonry structure, and then core beam is poured to form a whole, therefore, the constructions will be gradually located at a “tray” with enough rigidity, which solves the structural damage caused by inadequate bearing capacity of foundation soil or unsymmetrical support. In actual masonry structure protection, there have been successful examples where such technology is used, however, till now its related fundamental problems have not been researched yet. In this paper, based on study of on-site actual measurement, its fundamental is introduced, such items as action mechanism of box girder and soil body, calculation of jacking force and its influencing factors, and more, are discussed and empirical formula for calculation of jacking force is presented.

Abstract:

Rehabilitation of major mandibular defects after tumor resection has become a serious challenge for surgeons. In this research, four various models were designed to repair a critical mandibular lateral defect. Biomechanical behavior of the models was assessed by Finite Element Method. These models are including Fibular-Free Flap (FFF), Customized Prosthesis (CP), Tray Implant without Bone Graft (TI-wo-BG), and Tray Implant with Bone Graft (TI-w-BG). FFF is a subset of microvascular free flap technique in which some segments of patient’s fibula bone are used to restore mandibular defects. CP is a hollow and light prosthesis which is fabricated using Additive Manufacturing technology from Ti alloy powder. TI-wo-BG is similar to a crib which is designed according to the geometry of the patient’s mandible. TI-w-BG, in fact, is a TI-wo-BG which is filled with small cortico-cancellous chips in order to benefit potential profit of bone grafting. The chewing operation and loading on the mandible was simulated considering the three mandibular muscular forces including masseter, medial pterygoid, and temporalis. The result of FEM analysis of TI-wo-BG and TI-w-BG showed that in both models, screw number 6 endured a strain of 5684 and 2852[Formula: see text][Formula: see text]m/m which exceeded pathological and mild overload risk, respectively. This may increase the probability of screw loosening and system failure. The results proved the stability of the FFF and CP models. In addition, it can be concluded that stress and strain on the screw’s interfaces can decrease by improving the plate and increasing the friction at the interface of plate, bone and screw.

Full text

Abstract:

The Banuchi graft dispenser is an instrument for transplanting a plurality of hair grafts into preformed holes that facilitates and reduces the time of the implant procedure. The graft dispenser is an elongated hollow tube having both proximal and distal ends open to facilitate the hair graft loading process. It has an open channel extending along the length of the tube that holds the grafts, simplifying the counting process during the procedure. This instrument offers many advantages. The most attractive advantage for both patients and surgeons is that it reduces the time of implantation significantly. This reduction in time is due to the fact that with the graft dispenser, the surgeon can use the instrument not only to hold the grafts, but to dilate the preformed incisions and make the insertion more accurately and quickly. The new instrument has been designed in stainless steel and soon will be available in disposable plastic for further convenience. A multiple-channel instrument with a common funnel has been tested and proven to be very useful. A special tray to keep the loaded grafts in saline solution has also been designed.

Abstract:

AbstractWe have investigated the formation of 10-50 mm long ice spikes that sometimes appear on the free surface of water when it solidifies. By freezing water under different conditions, we measured the probability of ice-spike formation as a function of: (1) the air temperature in the freezing chamber, (2) air motion in the freezing chamber (which promotes evaporative cooling), (3) the quantity of dissolved salts in the water, and (4) the size, shape and composing material of the freezing vessel. We found that the probability of ice-spike formation is greatest when the air temperature is near -7°C, the water is pure and the air in the freezing chamber is moving. Even small quantities of dissolved solids greatly reduce the probability of ice-spike formation. Under optimal conditions, approximately half the ice cubes in an ordinary ice-cube tray will form ice spikes. Guided by these observations, we have examined the Bally-Dorsey model for the formation of ice spikes. In this model, the density change during solidification forces super cooled water up through a hollow ice tube, where it freezes around the rim to lengthen the tube. We propose that any dissolved solids in the water will tend to concentrate at the tip of a growing ice spike and inhibit its growth. This can qualitatively explain the observation that ice spikes do not readily form using water containing even small quantities of dissolved solids.

Abstract:

Purpose: To present an experimental strategy for successfully capturing the margins of prepared single teeth with an intraoral scanner (IOS). Methods: The protocol was as follows: (1) an intraoral impression was captured with an IOS, without taking care of the visibility of the margins; (2) a partial analog impression was taken by means of a 3D-printed custom tray filled with polyvinylsiloxane light, after the removal of a retraction cord; (3) the hollow portion of the analog impression, with the preparation margins clearly visible, was scanned extraorally with the same IOS; (4) the scan of the analog impression was imported into computer-assisted-design (CAD) software, where its normals were inverted; (5) the scan with inverted normals was registered on the first intraoral scan, and replaced it; (6) the technician designed the final restoration, which was fabricated and delivered for application. The study outcomes were: (1) the marginal adaptation of the final crown; (2) the quality of interproximal contacts; and (3) the quality of occlusal contacts. Results: Thirty patients (18 males, 12 females; mean age 51.3 ± 11.6 years) were selected for this study. All these patients were restored with a monolithic translucent zirconia crown, fabricated following the aforementioned protocol. The clinical precision and the marginal adaptation of the crowns were optimal, interproximal contact points were perfect, and the only necessary adaptations were occlusal, with some minor precontacts that had to be polished. Conclusions: The present protocol seems to be compatible with the fabrication of clinically precise zirconia crowns. Further studies are needed to confirm these results.

Full text

Abstract:

This is the first comprehensive camera trap study to examine hollow usage by wildlife in the canopy of trees. Eighty cameras directed at tree hollows were deployed across eight sites in nine species of eucalypt in north-east New South Wales. In total, 38 species (including 21 birds, 9 mammals and 8 reptiles) were recorded at hollow entrances over a three-month period. There was a significant difference between wildlife hollow usage associated with site disturbance and tree growth stage (ANOSIM, P > 0.05); however, there was no significant difference associated with tree hollow diameter (ANOSIM, P > 0.05). The level of anthropogenic disturbance at each site, including vegetation modification of the understorey, was a significant predictor of species presence. Despite the limitations of using camera traps in the canopy of trees this study demonstrates the potential to garner useful insights into the ecology and behaviour of arboreal wildlife.

Abstract:

Abstract We explored the dependence of some Cetoniidae species on saproxylic environments and microhabitats in a Mediterranean oak forest by analyzing species collected using different kinds of traps—log emergence, hollow emergence, and interception traps—and the sex ratio of the species in each trap. Comparing the sex ratio of the species collected via emergence versus interception was useful to unravel the degree of dependence on saproxylic microhabitats. Among the species studied, Cetonia aurataeformis Curti, 1913 (Coleoptera: Cetoniidae) was the only obligate tree hollow inhabitant. Special attention should thus be paid to the maintenance of tree hollows for the species’ conservation in Mediterranean forests. A gradient of dependence on tree hollows was established from the more dependent Protaetia (Potosia) cuprea (Fabricius, 1775) (Coleoptera: Cetoniidae) and Protaetia (Potosia) opaca (Fabricius, 1787) (Coleoptera: Cetoniidae) to the less dependent Protaetia (Netocia) morio (Fabricius, 1781) (Coleoptera: Cetoniidae). All the latter species can be considered facultatively dependent, to varying degrees, on tree hollows. By contrast, the saproxylic affinity of Protaetia (Netocia) oblonga (Gory and Percheron, 1833) (Coleoptera: Cetoniidae), Tropinota squalida (Scopoli, 1783) (Coleoptera: Cetoniidae) and Oxythyrea funesta (Poda, 1761) (Coleoptera: Cetoniidae) was doubtful. Generally, the sex ratio of the studied species was female-biased. A possible explanation may be local male competition for females, suggesting the Cetoniinae is a female world. However, the range of difference in the female-biased sex ratio among species suggests it is important to explore other possible causes, such as differences in dispersal abilities.

Abstract:

We present a novel and simple vapour-cell magneto-optical atom trap in a pyramidal and a conical hollow mirror cavity. A single laser beam having modulation sidebands at microwaves is used for cooling, trapping and repumping of rubidium atoms. When the laser is circularly polarized and sent into the hollow region, three pairs of counterpropagating beams are automatically produced therein, having the same polarization configuration as in the conventional six beam magneto-optical trap. The precooled atom sources thus produced may be used to obtain much colder and denser atoms for study of their quantum statistical properties.

Abstract:

The occasional malignant transformation of intracranial epidermoid cysts into squamous cell carcinomas remains poorly understood; the development of an in vitro cyst model is urgently needed. For this purpose, we designed a hollow nanofiber sphere, the “nanofiber-mâché ball.” This hollow structure was fabricated by electrospinning nanofiber onto alginate hydrogel beads followed by dissolving the beads. A ball with approximately 230 mm3 inner volume provided a fibrous geometry mimicking the topography of the extracellular matrix. Two ducts located on opposite sides provided a route to exchange nutrients and waste. This resulted in a concentration gradient that induced oriented migration, in which seeded cells adhered randomly to the inner surface, formed a highly oriented structure, and then secreted a dense web of collagen fibrils. Circumferentially aligned fibers on the internal interface between the duct and hollow ball inhibited cells from migrating out of the interior, similar to a fish bottle trap. This structure helped to form an adepithelial layer on the inner surface. The novel nanofiber-mâché technique, using a millimeter-sized hollow fibrous scaffold, is excellently suited to investigating cyst physiology.

Abstract:

The genus Utricularia (Lentibulariaceae) comprises about 220 species and represents the largest genus of carnivorous plants (Taylor 1989; Guisande et al. 2007). The trap of Utricularia is a hollow utricle usually 1-4 mm long, with walls mostly two cells thick, and filled with water. It is the most sophisticated trap within carnivorous plants (Juniper et al. 1989), with a variety of glands and trichomes both on the inner and outer surfaces (see Figure 1). After the prey irritates trigger hairs situated close to the trap door, it is sucked in as a result of the underpressure maintained inside the utricle. After firing, the trap restores the underpressure by rapidly removing approximately 40% of the water from the lumen. This process lasts about 30 min and the trap is ready to fire again (Sydenham & Findlay 1975).

Abstract:

The alternate-year summer fallow wheat production system predominates in the semi-arid prairie regions of Montana. These farms consist of the current crop and idle fields in which the previous year's crop was located. Larvae of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), overwinter in post-harvest wheat stubble. Adults appear and disperse to new crops during the following growing season. Adults begin oviposition as soon as suitable hosts are encountered; therefore, larval infestations usually are concentrated along field borders. We tested several types of trap strips as intercepts to reduce dispersion of adult sawflies into fields. The most successful system was a fall-planted winter wheat trap that protected spring-planted wheat. These trap strips utilized the “border effect” as well as the higher attractiveness of the earlier maturing winter wheat. In another trial, losses were reduced by planting a semi-resistant solid-stemmed wheat cultivar within the border of a comparatively higher yielding hollow-stemmed cultivar.

Full text

Abstract:

Background and objectivesThe aim of the study was to describe the radiological anatomy of the pseudo-suprascapular notch—a structure localized at the floor of the supraspinatus fossa, just below the true suprascapular notch. In sonographic examination, it may imitate the suprascapular notch leading to misidentification of these structures.MethodsUltrasound assessment of the suprascapular notch region was performed in 100 patients who underwent chest CT due to other indications. The presence of the suprascapular notch and the pseudo-suprascapular notch was evaluated together with their maximal width and depth using both techniques. The correlation between the dimensions of these two notches was assessed.ResultsThe pseudo-suprascapular notch was recognized in 82 patients. In four of them the suprascapular notch could not be visualized in ultrasound due to obscuring clavicle. In all cases the pseudo-suprascapular notch contained a small artery. In comparison to the suprascapular notch, the pseudo-suprascapular notch was significantly narrower and shallower, except for 10 cases with vestigial suprascapular notch where the pseudo-suprascapular notch was the only hollow in this region. The dimensions of both structures did not correlate with each other. Finally, the pseudo-suprascapular notch did not present any significant asymmetry (p=0.1185) or sexual dimorphism (43 women vs 38 men, p=0.2025).ConclusionsThe pseudo-suprascapular notch is a hollow for nutrient vessels that can be mistaken for the regular suprascapular notch in cases of difficult sonographic navigation.

Abstract:

Abstract Tetraphenyl phosphonium-modified organoclay (TPP-Mt) was prepared by modifying montmorillonite-rich Thai bentonite via ion exchange. TGA results revealed that TPP-Mt possessed high thermal stability, where degradation occurred at a temperature range of 418-576°C. The obtained TPP-Mt/PP nanocomposites exhibited degradation at higher temperatures than PP (410-420°C vs. 403°C). Fibers of different cross-sectional shapes (circular, circular hollow, and cross) containing 1, 2 and 3%wt TPP-Mt were prepared and characterized. Nonwovens of 3%wt TPPMt/PP fibers were fabricated for flame retardant test. From results, nonwovens of TPP-Mt/PP fibers exhibited self-extinguishing characteristic and the areas of burning were less than that of PP nonwoven (14.5-31.6% vs. 95.6%). Nonwovens of cross-shaped fibers showed the best flame retardant property, followed by those of circular hollow and circular fibers. The flame retardant properties observed in nonwovens were explained due to the inter-fiber spaces between cross-shaped fibers and center hole in circular hollow fibers, which could trap initiating radicals inside, thus reducing flame propagation. In addition, large surface area in cross-shaped fibers could help in increasing the flame retardant effectiveness due to more exposure of TPP-Mt particles to the flame. Knowledge obtained in this study offered an approach to produce flame retardant nonwovens via a combination of modified organolcay and fiber shape.

Abstract:

Este artigo traz um estudo de caso sobre a percepção ambiental de moradores vizinhos a um fragmento de floresta urbana - Mata da Paixão, na cidade de São José do Rio Pardo, SP. Para determinar a percepção do residente no entorno do fragmento, foi realizado um levantamento, utilizando técnicas de geoprocessamento e aplicação de questionários semiestruturados para avaliar perspectiva socioambiental dos moradores. Assim, foi possível sistematizar informações da relação entre a comunidade e o remanescente de mata no espaço urbano. Como resultado, foi produzido um mapa atualizado da área. Sobre a perspectiva dos moradores, em uma visão geral, a maioria dos moradores afirmou que morar perto de um fragmento florestal traz mais benefícios do que desvantagens para a comunidade, embora seja notável a negligência dos órgãos públicos quanto à área. Os achados indicam que a relação entre o ocupante urbano, o bairro e o entorno, neste caso, ocorre de forma positiva. Assim, iniciativas de agentes públicos locais são necessárias para manter a relação ambiental harmônica em áreas urbanas.

Abstract:

A ‘sandwich'-structured TiO 2 NR/HGN/CdS photoanode was successfully fabricated by the electrophoretic deposition of hollow gold nanospheres (HGNs) on the surface of TiO 2 nanorods (NRs). The HGNs presented a wide surface plasmon resonance character in the visible region from 540 to 630 nm, and further acted as the scatter elements and light energy ‘antennas' to trap the local-field light near the TiO 2 NR/CdS layer, resulting in the increase of the light harvesting. An outstanding enhancement in the photochemical behaviour of TiO 2 NR/HGN/CdS photoanodes was attained by the contribution of HGNs in increasing the light absorption and the number of electron-hole pairs of photosensitive semiconductors. The optimized photochemical performance of TiO 2 NR/HGN/CdS photoanodes by using plasmonic HGNs demonstrated their potential application in energy conversion devices.

Abstract:

We use molecular mechanics and DFT calculations to analyze the particular electronic behavior of a giant nanoball. This nanoball is a self-assembled M12L24 nanoball; with M equal to Pd+2; Cr; and Mo. These systems present an extraordinarily large cavity; similar to biological giant hollow structures. Consequently, it is possible to use these nanoballs to trap smaller species that may also become activated. Molecular orbitals, molecular hardness, and Molecular Electrostatic Potential enable us to define their potential chemical properties. Their hardness conveys that the Mo system is less reactive than the Cr system. Eigenvalues indicate that electron transfer from the system with Cr to other molecules is more favorable than from the system with Mo. Molecular Electrostatic Potential can be either positive or negative. This means that good electron donor molecules have a high possibility of reacting with positive regions of the nanoball. Each of these nanoballs can trap 12 molecules, such as CO. The nanoball that we are studying has large pores and presents electronic properties that make it an apposite target of study.

Abstract:

Abstract SPT-100 electrostatic thruster is considered, and the effects of magnetic circuit is studied by introducing magnetic screen. The magnetic flux density in the discharge channel is generated with the help of one inner coil and four outer coils. The radial magnetic field has to be maximum near the exit plane of the thruster to trap the electrons in acceleration region which are emitted from an external hollow cathode. These electrons help in increasing the ionization rate of the propellant gas. This is obtained by placing magnetic poles near exit plane. It helps to traps the electrons emitted from the external hollow cathode. The magnetic circuit should be designed such that the magnetic flux density is near to zero at the anode plane to reduce interaction of electrons with channel walls. To arrive at such better design, magnetic screens are used. Computational simulations are performed to quantify the magnetic flux density distribution along the channel using COMSOL Multiphysics software. The simulation results show that the obtained radial magnetic flux density is maximum near the exit plane, and the magnetic screens help in reducing the magnetic field at the anode region while maintaining the maximum magnetic field at the exit plane.

Abstract:

Abstract Celery was transplanted on 10 Aug at the Univ. of Calif. South Coast Field Station in Santa Ana, CA. The crop was sprinkle irrigated for 3 wk and drip irrigated thereafter. Experimental plots were 3 beds wide (40-inch centers) by 50 ft long with 1 untreated buffer row between plots. Each bed contained 2 rows of plants 6-8 inches apart. Treatments were replicated 4 times in a randomized complete block design. Insecticides were applied weekly with a tractor-mounted boom sprayer from 25 Aug through 10 Nov, except on 29 Sept when rain precluded treatment. As plant height and foliage density increased, nozzles varied from 1-3 per row and carrier (H2O) increased from 50-100 gal/acre. Hollow cone nozzles incorporated D3 orifice disks, #25 cores, and 50-mesh screens. All treatments except Avermectin included 0.04% spreader-sticker (Leaf Act 40). Evaluation of beet armyworm and black cutworm damage was based on the number of damaged plants found in 10 randomly selected plants/replicate (80/ treatment) from the center 2 rows of each replicate at harvest. When plants reached a suitable height, 4 inches X 8 inches pupal trays were inserted between rows and the no. of leafminer larvae, puparia, and pupae and leafminer parasites collected in trays were counted on 11, 18, 26 Oct and 1 and 8 Nov. Four trays were counted in each replicate.

Abstract:

In order to enhance future trapping of the western pygmy possum (Cercartetus concinnus) and minimise the capture of non-target species in the context of animal ethics, we examined the effectiveness of several pitfall-trap capture methods and described capture patterns at Innes National Park, South Australia. For 2606 trap-nights, 78 (2.99 per 100 trap-nights) captures were pygmy possums (70 individuals). They represented 69% of the 113 vertebrates captured, followed by house mice (Mus domesticus) (22%). Nocturnal captures of pygmy possums varied with season (5.21 per 100 trap-nights in spring and summer, and 1.02 in autumn and winter). Males were more commonly captured than females. Half of the pygmy possums used the artificial shelters provided in the traps. We alternated 39-cm-deep and 31-cm-deep pitfall traps along trap lines, with and without drift netting. Pitfall depth did not significantly affect the capture rate of pygmy possums, but house mice were captured significantly more often in deep pitfalls. Use of a drift net did not affect the capture of pygmy possums, but increased mouse captures. These results have significant ethical implications because the use of ‘shallow’ traps and the elimination of the drift net minimised the capture of non-target mice. We recommend reporting trapping details precisely, because a difference of only 8 cm in trap depth can have a significant impact on species selected for capture. Our study also showed that pygmy possums are able to use a range of structures for daily shelter and are not dependent on hollows.
