Opis:
The study aimed to conclude on the up-to-date state of the organisational ecology theory concerning relations between organisational ageing and organisational ecology, enhanced by social and ecological systems and ecological management. The applied method included analytical and reflective concluding, based on the synthesis of findings from a critical literature review. It was concluded that: (i) organisational ageing generates some of the most important consequences in organisational ecology; however, there is still no consensus on what kind of consequences prevail; (ii) at population level, the adaptation of organisational structures occurs with the replacement of old organisations that fail to adapt by the new ones; (iii) under the prevalent backdrop of radical structural and strategic changes, individual organisations are subject to inertial forces and thus are confronted with limitations to their success; (iv) ageing has positive consequences for innovative activities of older companies; and (v) the higher the density and concentration of industry, the higher the rates of founding firms and the lower the rates of mortality.

Opis:
The use of the Amazon Web Services cloud enables new functionalities that are not possible with traditional solutions: low latency, local data processing and storage, and direct connectivity to other cloud services. Reimagining the way IoT connectivity services are presented by combining AWS cloud technology with mobile connectivity offers rapid prototyping to help connect devices natively over Wi-Fi. For this, the MQTT communication protocol is used to interact with the IoT device and exchange data, which allows controlling the basic functions of a sensor node. The installation is realized through a software development kit (SDK), which allows the creation of an application for Android devices. This solution gives the option to integrate together, improving the connectivity of the IoT system. The results enable board logging and network configuration, and can also be used to control the IoT device. The embedded firmware provides the required security functions.

Opis:
The crime rates in Mexico have been increasing in recent years; every day, there are reports on social media and in the news where assaults and verbal aggression by criminals can be seen. Public transportation units suffer from violence that authorities have not been able to reduce despite their efforts. This is why we have developed a fuzzy logic model that can adapt to almost any scenario thanks to the dynamism that we have implemented in each of its stages. We have obtained promising results that we believe will be of great help to the authorities for detecting the exact moment in which verbal aggression that is typical of a violent assault is happening in real time. This is a tool to help the authorities, not a substitution; we are simply making use of the latest technologies that are available to us. The goal of this paper is to provide a novel method for Mexican authorities in Mexico City in order to help the actual surveillance systems make faster decisions about whether violent assaults are happening or not.

Opis:
The textile industry is very important because its products are widely used by society, however, this activity has a great contribution to the contamination of water resources due to its effluents that contain large amounts of colorants, among which is the blue of methylene (MB) and methyl orange (MO) that can cause damage to the health of living being. For this reason the present study concerned the removal of these dyes by adsorption using Eichhornia Crassipes (Water lily) with different treatments. The results show that the chemisorption removal process using two sites per dye molecule having an exothermic nature for the water-treated lily and for the NaOH-treated lily is endothermic. The maximum adsorption capacities of 228.9 mg/g for MB (60 °C) and 155.38 mg/g (30 °C) for MO with the NaOH treatment were achieved. The SEM analysis shows that there are significant changes in the surface due to the treatments. The XRD patterns indicate that with the pretreatment with NaOH the crystallinity of WL increases while the treatment with water maintains the presence of amorphous cellulose. In the FTIR spectra, the bands corresponding to different functional groups such as lignin, cellulose and hemicellulose that participate in the adsorption of both dyes are observed.

Opis:
Various applications of Radio Frequency IDentification (RFID) technology in the medical environment are characterised. The electromagnetic field (EMF) emitted by RFID handheld readers (RFID guns) is characterised and evaluated with respect to humans exposure metrics – the strength of the electric field affecting anyone present near various UHF (ultra-high frequency) RFID guns and the specific absorption rate (SAR) values in their body. UHF RFID systems are the most popular of such systems used in hospitals. The performed studies indicate that the EMF exposure level near the RFID gun antenna and SAR values (a measure of the thermal effects of EMF exposure) caused by exposure from the RFID reader may exceed the limits of the electric field and SAR issued by international guidelines or legislation. Potentially excessive exposure to EMF emitted by UHF RFID readers is not limited to the user of the device, but may also apply to patients or bystanders. Only UHF RFID guns with an EMF emission lower than 1 W may be considered as an insignificant source of human exposure. The use of readers with a radiated power exceeding 1 W requires the evaluation of the EMF level using measurements, and also the evaluation of SAR by numerical modelling in the case of their use in close proximity to humans. In all cases, insufficient electromagnetic immunity of electronic devices (including medical implants) should be considered near RFID guns at least up to half of the reading range away from the RFID reader. The electromagnetic hazards related to the use of RFID guns may be limited by relevant preventive measures, as shown in this paper, together with the principles of an in-situ evaluation of electromagnetic hazards near the UHF RFID guns.
Scharakteryzowano różne zastosowania technologii identyfikacji radiowej (RFID) w środowisku medycznym. Pole elektromagnetyczne emitowane przez ręczne czytniki RFID (RFID guns) zostało scharakteryzowane i ocenione w odniesieniu do miar narażenia ludzi – natężenia pola elektrycznego oddziałującego na osoby znajdujące się w pobliżu różnych czytników RFID UHF (ultrawysokiej częstotliwości) i współczynnika SAR w ich ciele. System UHF RFID jest najpopularniejszym z systemów RFID użytkowanych m.in. w szpitalach. Przeprowadzone badania wskazują, że poziom ekspozycji na pole elektromagnetyczne w pobliżu anteny ręcznego czytnika RFID i wartości SAR (miara skutków termicznych oddziaływania pola elektromagnetycznego) spowodowane tą ekspozycją mogą przekraczać limity, opublikowane w zleceniach międzynarodowych lub przepisach. Nadmierna ekspozycja na pole elektromagnetyczne emitowane przez czytniki RFID UHF może dotyczyć nie tylko użytkownika urządzenia, ale również pacjenta lub osoby postronnej. Tylko ręczne czytniki RFID UHF o emisji pola elektromagnetycznego poniżej 1 W można uznać za nieistotne źródło narażenia ludzi. Korzystanie z czytników o mocy przekraczającej 1 W wymaga oceny poziomu pola elektromagnetycznego za pomocą pomiarów, a również oceny SAR za pomocą modelowania numerycznego w przypadku ich użycia w bezpośredniej bliskości ludzi. We wszystkich przypadkach niewystarczającą odporność elektromagnetyczną urządzeń elektronicznych (w tym implantów medycznych) należy rozważyć w pobliżu czytników RFID co najmniej do odległości od czytnika RFID równej połowie jego zasięgu odczytu. Zagrożenia elektromagnetyczne związane z używaniem ręcznych czytników RFID mogą być ograniczone przez odpowiednie środki ochronne, jak pokazano w tym artykule, wraz z zasadami oceny zagrożeń elektromagnetycznych in-situ w pobliżu ręcznych czytników UHF RFID.

Opis:
Mango cv. ‘Tommy Atkins’ is a highly appreciated fruit for its organoleptic characteristics and its resistance to minimal processing. However, some operations as peeling and cutting can generate microbial contamination and loss of bioactive compounds. Ultraviolet short wave (UV-C) is an alternative technology for fresh-cut products that leads to microbial inactivation and the increase of beneficial compounds. The effect of a UV-C dose of 6 kJ/m2 was evaluated on quality attributes of fresh-cut 'Tommy Atkins' mango during days 0, 3, 6, 9, and 12 of storage (5°C, relative humidity: 85-90%), and compared with a positive control (conventional method by immersion in 10 mg/L sodium hypochlorite solution) and a negative control (without treatment). Physicochemical analysis (titratable acidity, pH, total soluble solid content, and firmness), superficial color evaluation, determinations of microbial counts, contents of total carotenoids, phenolics and flavonoids, and antioxidant capacity assays were performed. The results showed that UV-C treatment allowed to preserve microbial safety and superficial color of stored fresh-cut mango, and to increase the content of total carotenoids, which was 19.34 and 26.50 mg β-carotene/100 g fresh weight (FW) for control and UV-C treated sample at day 12 of storage, respectively. The DPPH• scavenging activity of the UV-C treated mango was also higher (0.60 mM TE/g FW) compared to control (0.27 mM TE/g FW) at the end of storage. However, UV-C treatment caused loss of firmness. Some native microorganisms of mango adapted to the stress caused by the treatments and the storage.
