Opis:
Colorectal cancer (CRC) is the third most commonly diagnosed malignancy and the fourth most deadly cancer in the world for which surgery is the main treatment. Colorectal surgery can be performed through a wide incision in the abdomen or using minimally invasive surgical (MIS) techniques. Some of these techniques include transanal endoscopic microsurgery (TEM ), transanal minimally invasive surgery (TAMIS), transanal total mesorectal excision (TaTME ), and robot-assisted surgery. Studies increasingly confirm that resections using MIS techniques are safe, oncologically equivalent to open surgery and have better short-term results. These surgical approaches are, however, technically demanding and result in a steep learning curve. The main objective of this study is to review the different MIS techniques for colorectal surgery, as well as the training tools and programs designed to achieve the necessary surgical skills. Different training programs in colorectal surgery have been reported for the different surgical techniques analyzed. Most of these programs are based on training tools in the form of surgical simulators, physical and virtual, as well as the use of experimental and cadaveric models. However, structured training programs in minimally invasive colorectal surgery remain scarce, and there should be a consensus on the fundamental training aspects for the various surgical techniques presented. These training programs should ensure that surgeons acquire sufficient surgical skills to be competent in the development of these surgical techniques, improving the quality of the patient’s surgical outcomes.
Rak jelita grubego (RJG) jest trzecim co do częstotliwości rozpoznawania nowotworem złośliwym na świecie, a także czwartą przyczyną zgonów na nowotwory złośliwe. Głównym elementem leczenia RJG jest operacja, którą można wykonać przez rozległe nacięcie powłok lub za pomocą technik minimalnie inwazyjnych. Do tych drugich należą: endoskopowa chirurgia transanalna (TEM ), przezodbytowa chirurgia minimalnie inwazyjna (TAMIS), przezodbytowe całkowite wycięcie mezorektum (TaTME ) oraz chirurgia wspomagana robotowo. Analizy danych potwierdzają, że techniki minimalnie inwazyjne są bezpieczne, równie skuteczne onkologicznie co techniki tradycyjne, a także wiążą się z szybszym powrotem chorych do pełnej sprawności. Ich wspólną cechą są niestety wysokie wymagania techniczne oraz długa krzywa uczenia. W artykule omówione zostały różne techniki minimalnie inwazyjne stosowane w leczeniu RJG oraz metody nauczania tych technik. Jak dotąd opracowano wiele sposobów szkolenia dla różnych technik operacyjnych. Większość opiera się na symulatorach chirurgicznych zarówno rzeczywistych, jak i wirtualnych oraz na wykorzystaniu modeli eksperymentalnych i preparatów z ludzkich zwłok. Niestety usystematyzowane modele szkolenia w minimalnie inwazyjnej chirurgii RJG są nadal rzadkością. Widać wyraźnie potrzebę opracowania konsensusu dotyczącego szkolenia w poszczególnych metodach operacyjnych. Tego rodzaju programy powinny zapewnić uczestniczącym w nich chirurgom zdobycie wiedzy pozwalającej na skuteczne wykonywanie zabiegów w celu zapewnienia pacjentom jak najlepszych efektów leczenia.

We investigated the short-term effects of spent coffee grounds on the physical properties of two Mediterranean agricultural soils (Calcisol and Luvisol). The in vitro assay was performed with two spent coffee grounds doses (60 and 240 Mg ha-1), two incubation times (30 and 60 days) and two modalities: with and without lettuce seedlings (Lactuca sativa var. longifolia). Spent coffee grounds addition increased water retention at -33 and -1500 kPa, and decreased bulk density and plant-available water content. With spent coffee grounds, the percentage of macroaggregates increased, the percentage of meso- and microaggregates decreased and the structural stability of all types of aggregates increased. The stereomicroscopy images showed that: the structural aggregates were rounded, the porosity increased by 316%, the structure was ordered into smaller aggregates, the incorporation of spent coffee grounds particles could occur in intraped cracks and spent coffee grounds particles could act as a binding agent. Scanning electron microscopy also showed that spent coffee grounds particles interacted with mineral particles and integrated into soil structure; moreover, fungal hyphae also developed on many spent coffee grounds particles. If spent coffee grounds effects are compared with those described in the literature for other organic amendments, the same trend was observed in most of the soil physical properties although with a different intensity, principally with regard to structural stability.

Opis:
Natural sounds are essential elements for ecosystems, and therefore necessary for many ecological functions, forming what is called “natural soundscapes”. The Natural Reserve Laguna del Portil (NRLP), located in the southwest of the Iberian Peninsula, is an ecosystem which was declared by Spanish authorities as Protected Natural Reserve. In the south area of the NRLP, there is a regional road with high traffic intensity, which affects the soundscapes of this natural reserve. In this study, the road potential noise impact on the natural sounds of the NLRP is analysed. This analysis was done both in winter and summer, and also using two independent methods: 1) spatial sampling measures in 43 different points of the NRL; and 2) noise mapping using noise levels prediction software. From the comparison of the results of both methods and seasons the following conclusions were reached: 1) an approach to the natural soundscape of NRLP both in winter and summer, 2) the acoustic impact of the road on the NRLP, and 3) the variation of the traffic noise depending on the distance to the road, and its seasonal variation. This study could be to improve the management of the NRLP and to help to preserve the natural soundscape of the reserve.

Opis:
Noise Monitoring Networks (NMNs) have been implemented in many cities by town councils, allowing them to know, in real time, the environmental noise levels in the busiest streets by the continuous measurement of selected acoustic parameters throughout the year. NMNs are aimed at: 1) detecting areas of the city that breach guidelines for acoustic quality objectives; 2) obtaining noise data needed to develop and implement action plans; and 3) informing the public about the permissible acoustic pollution for different districts and times of day. The aim of this work was to analyse data from the NMN of the city of Huelva (Spain), in order to study the influence on the noise of re-asphalting the busiest streets. The street pavements improve LAeq, 24 h from 3 up to 8 dB(A), depending on the type of the route. These results could be used by council authorities in deciding when to undertake the re-asphalting of the streets of Huelva, and to select the type of asphalt that should be used.

Opis:
In this paper, explain the preparation of CaTiO3 ceramics synthesized by the solid-state reaction method. Calcium carbonate and titanium dioxide were high energy mixed in stoichiometric amounts, and the obtained mixture was calcined at different temperatures (800, 900, 1000 and 1300ºC) for 2h. The obtained samples were characterized by measurement of particle size, Energy Dispersive X-Ray (EDX) Analysis; differential thermal analysis, X-ray diffraction and SEM images. XRD patterns indicated that CaTiO3 ceramics with the structure of perovskite is obtained from calcined powders at 1,300°C for 2h. SEM images show the formation of a very fine and homogeneous morphology. The measured values of electrical resistivity were within the typical range of insulating materials and approach values corresponding to insulating ceramics.

Opis:
The paper is based on the premise that customers aspire to achieve maximum satisfaction of the products or services they buy so that knowledge of customer satisfaction enables an organization organized according to provide quality services assuming that levels higher quality leads to higher levels of customer satisfaction. Its empirical research was carried out in the tourist destination Holguín, northeastern Cuba, including more than 2,000 tourists and 70 tourism service providers, and was designed to provide information on the relationship between the level of tourist satisfaction and the variables of quality assurance in the destination. By means of the compilation and analysis of the obtained data a model of structural equations was constructed to visualize the nature of the relations that they were intended to demonstrate. The obtained results indicate that there are relations between the variables that assure the quality and the satisfaction of the customer leaving identified the possibilities of improvement.

Opis:
Software startup companies develop innovative, software-intensive products within limited time frames and with few resources, searching for sustainable and scalable business models. Software startups are quite distinct from traditional mature software companies, but also from micro-, small-, and medium-sized enterprises, introducing new challenges relevant for software engineering research. This paper’s research agenda focuses on software engineering in startups, identifying, in particular, 70+ research questions in the areas of supporting startup engineering activities, startup evolution models and patterns, ecosystems and innovation hubs, human aspects in software startups, applying startup concepts in non-startup environments, and methodologies and theories for startup research. We connect and motivate this research agenda with past studies in software startup research, while pointing out possible future directions. While all authors of this research agenda have their main background in Software Engineering or Computer Science, their interestin software startups broadens the perspective to the challenges, but also to the opportunities that emerge from multi-disciplinary research. Our audience is therefore primarily software engineering researchers, even though we aim at stimulating collaborations and research that crosses disciplinary boundaries. We believe that with this research agenda we cover a wide spectrum of the software startup industry current needs.

Opis:
Cardabiodon ricki and Cardabiodon venator were large lamniform sharks with a patchy but global distribution in the Cenomanian and Turonian. Their teeth are generally rare and skeletal elements are less common. The centra of Cardabiodon ricki can be distinguished from those of other lamniforms by their unique combination of characteristics: medium length, round articulating outline with a very thick corpus calcareum, a corpus calcareum with a laterally flat rim, robust radial lamellae, thick radial lamellae that occur in low density, concentric lamellae absent, small circular or subovate pores concentrated next to each corpus calcareum, and papillose circular ridges on the surface of the corpus calcareum. The large diameter and robustness of the centra of two examined specimens suggest that Cardabiodon was large, had a rigid vertebral column, and was a fast swimmer. The sectioned corpora calcarea show both individuals deposited 13 bands (assumed to represent annual increments) after the birth ring. The identification of the birth ring is supported in the holotype of Cardabiodon ricki as the back-calculated tooth size at age 0 is nearly equal to the size of the smallest known isolated tooth of this species. The birth ring size (5-6.6 mm radial distance [RD]) overlaps with that of Archaeolamna kopingensis (5.4 mm RD) and the range of variation of Cretoxyrhina mantelli (6-11.6 mm RD) from the Smoky Hill Chalk, Niobrara Formation. The revised, reconstructed lower jaw dentition of the holotype of Cardabiodon ricki contains four anterior and 12 lateroposterior files. Total body length is estimated at 5.5 m based on 746 mm lower jaw bite circumference reconstructed from associated teeth of the holotype.

Opis:
Due to the problem that represents the accelerated production of waste from the consumption of polyethylene terephthalate (PET), it becomes necessary to look for alternative solutions; chemical recycling is a suitable method for conversion into a material with potential application in concrete additive, such as unsaturated polyester resins; with the above improvements and conservation of non-renewable raw materials can reduce the environmental impact. This investigation was focused on obtaining the synthesis of a polymeric resin by the method of glycolysis, and their characterization by Infrared Spectroscopy (FT-IR); the results show that the recycled materials (PET and its processing) are similar to reagents made from primary materials so that it is considered feasible to use in the intended application.

Opis:
Here we report a new Early Pleistocene record of agamid lizards (Agamidae indet.) from the Spanish locality of Quibas (ca. 1.3–1.0 Ma), which represents the latest evidence of the family in Western Europe. Up to now, the family Agamidae was considered to have disappeared in this region at 1.8 Ma. This new record implies the survival of agamid lizards for a large part of the Early Pleistocene in the southernmost Iberian Peninsula, probably because of favourable climatic and environmental conditions. Consequently, the formerly detected Pliocene / Pleistocene boundary is no longer recognisable in the evolution of the herpetological assemblages in Western Europe.
