Introduction: In Tehran with a population of 9 million currently, about 2.5 million tons municipal solid waste have been producing annually. Materials and Models: In this study by using Life Cycle Assessment (LCA) model an optimal system of waste management of Tehran was recommended. Based on the quantity and quality of waste in Tehran in 2013 and facilities, three scenarios were selected. First, current status (15% compost, 5% recycling and 80% landfill), second, the maximum use of the capabilities of waste of Tehran (70% compost, 20% recycled and 10% landfill ) and third, the optimal scenario according to conditions of Tehran (55% compost, 10% recycling, 5% energy recovery and 30% landfill). The IWM model and WRATE model was used for Phase II and Phase III, respectively. Results: Results of the conducting second Phase showed in compared to the first scenario by the second and third scenario, the amount of emissions was decreased 64% and 72%, respectively. The third phase results showed the third scenario has the lowest environmental impact in chosen six impact groups. Conclusion: Considering the quality and quantity of wastes in Tehran and also the current facilities, conducting the third scenario could be useful for reducing emissions, the external costs and environmental impacts.

The modelling of business processes is vital not only for business processmanagement, but also for implementation of enterprise systems. For example,when we look at the process life cycle introduced earlier, three of the sevenphases involve business process modelling, to a large extent. But apart fromthat, the models that are generated in these three phases are used in all the sevenphases of the business process management life cycle. The phases where thesemodels are developed are in the second phase of process modelling; and it isused in the third phase, where we do the analysis; and is used in the fourth phase,where we improve upon the as-is models, come up with the to-be models, andmodel them, using whatever tools that are available. But then, the to-be modelsthat are developed in the fourth phase are used in the process implementationphase, in the execution phase, in the monitoring phase, and even in the processidentification phase, when you think of it as a life cycle.

Forensic entomology frequently assists forensic medicine in legal investigations. It makes it possible to estimate the time of death when a cadaver is recovered at a relatively advanced stage of decomposition. In criminalistics practice, unburied bodies are found the most commonly, and therefore the fauna of these cadavers is the best investigated. The aim of this study was to collect a succession of insects and other invertebrates occurring on an unburied corpse. The experiment was conducted on the carcass of a cat euthanized due to an advanced cancer process. The carcass was colonized by three phyla of animals: Annelidae, Mollusca, and Arthropoda. They belonged to 7 classes and 10 orders. The most diverse were Arthropoda. They were classified into 5 classes: Insecta, Diplopoda, Malacostraca, Entognata, and Arachnida, and into 8 orders: Julida, Isopoda, Collembola, Diptera, Coleoptera, Hemiptera, Araneae, and Acari. The fly species Calliphora vicina from the family Calliphoridae is of particular interest among the insects collected because it is one of the fundamental indicator species whose life cycle makes it possible to determine an approximate time of death. During the study it was noted that arthropods occurred in a certain pattern of succession, predictable in forensic entomology. The first group was Calliphora vicina (Calliphoridae, Diptera), which laid eggs. The next (second) group consisted of first-instar C. vicina larvae and insects feeding on these larvae, such as Philonthus tenuicornis (Staphylinidae, Coleoptera). The first stage of succession was the appearance of eggs of C. vicina. The second phase was the appearance of adult flies other than Calliphoridae and of accidental species, as well as beetles (e.g. Philonthus tenuicornis, Staphylinidae, Coleoptera) feeding on larvae of C. vicina. The third phase of succession was the appearance of all larvae stages of C. vicina that continued and finished their life cycle.

Today, the production of various types of solid waste and the occurrence of related social, economic and environmental inconsistencies have faced the management of municipal services and waste with many problems in the areas of collection, transportation, processing and disposal of such waste. The purpose of this study is to assess the life cycle of the current management system in Yazd, Iran from the environmental and economic point of view and to determine the priority in the decision-making to improve waste management. There are many tools for assessing the environmental impacts and determining the priority in the decision-making, but one of the widely used methods is life cycle assessment (LCA). In this study, three different scenarios of waste management were defined. The first scenario is the unsanitary separation and landfill (according to current situation in Yazd), the second scenario is the separation, composting and anaerobic digestion, waste incineration plant, disposal of residues and ash in sanitary landfill, and the third scenario is the separation, composting and anaerobic digestion, and sanitary landfill. Then, using the Integrated Waste Management (IWM-2) software, the inventory of the environmental and economic burden of each scenario was analyzed and presented. In general, the assessment of Yazd municipal waste life cycle was performed to achieve the optimal scenario that has less environmental and economic burden. The third scenario was selected as the best management option in this respect.

The ponderal and size growths of 56 hand-reared ostriches, Struthio camelus australis, were studied at Parc zoologique de Paris. During the first year, three growth phases can be observed. The first phase occurs during the first week and is characterized by a physiological decrease in weight which is unavoidable. The second phase occurs from 8 days to 6 months and coincides with the period in which the most important growth in size takes place; it corresponds to one of the critical periods (during the second month) when many deformed legs are seen. During the following 6 months, the third phase, the growth in size is slower than the increase in weight. The growth of ostriches is an interesting indicator of the quality of breeding.

To obtain a high data rate that is commensurate with the growing demand for internet services, the fifth generation (5G) cellular networks will use the bandwidth beyond 6 GHz, called millimeters waves (mm-waves), to obtain a higher. The first phase (phase I) of the 5G network design for high user density, where the optimized microcells are deployed at carrier frequency 700 MHz with 20 MHz bandwidth. The second phase (phase II) of the design consists of the deployment of microcells which are operating at 3.6 GHz with 100 MHz bandwidth; this phase is planned to cover 200000 users within the province. The third phase (phase III) of the design is represented by the deployment of picocells, which are planned to operate at 26 GHz frequency and bandwidth 500 MHz; this phase is planned to cover 3,500,000 users within the province. Two types of modulation are adopted for the network (orthogonal frequency division multiplexing (OFDM) and 256 quadrature amplitude modulation (QAM)); the overall performance of the network is studied with regards to the percentage of coverage, power overlapping ratio, frequency interference, and quality of service (QoS).

BACKGROUND EasySeating is a mobile health (mHealth) app that supports the prescription of wheelchair and postural support devices (WPSD). It can be used by occupational therapists (OT) and physiotherapists (PT) who prescribe WPSD. The app offers a standardization of the prescription procedure, showing images, metrics and details that guide the prescriber to decide on the best equipment. It was developed with an iterative mixed-methods evaluation approach. Objective: The aim of this study was to investigate the processes involved in the prescription of WPSD and to propose, develop and evaluate a mHealth to support OT and PT prescribers. OBJECTIVE The aim of this study was to investigate the processes involved in the prescription of WPSD and to propose, develop and evaluate a mHealth to support OT and PT prescribers. METHODS This study was divided into three phases and was carried out as an iterative process composed of user consulting/testing (using a mixed-methods evaluation approach), system (re)design and software development. The first phase consisted of the collection of qualitative and quantitative data to map and understand the users requirements and of the development of the first prototype (v1) of the app. This data collection was performed through semi-structured interviews with 14 OT and PT prescribers, 5 specialized technicians and 5 WPSD users. The second phase aimed at improving the overall functionality of the app and consisted in the development, test and evaluation of the prototypes v1, v2, v3 and v4. A total of 59 prescribers tested and evaluated these prototypes by means of open interviews, semi-structured questionnaires and focus groups. The third phase focused in the usability aspects of the app. It consisted in the development and test of the prototype v5. Eight technology specialists assessed its usability through heuristics evaluation. RESULTS Data collected in phase one indicated there is a lack of standardization on the prescription of postural support devices (PSD). A divergent nomenclature for the PSDs was also found and classified in eight categories. These information guided the development of the first prototype of the EasySeating app. Phase two results pointed that the prescribers value the insertion of the app into their clinical practice, as it accelerates and increases the quality of the evaluation process and improves the organization of the prescription information. Significant suggestions for the improvement of the app were given during the users tests, including the use of images to represent the PSDs. The usability tests from the third phase revealed two strong issues that must be solved: the need of greater feedback and failures in the persistence of the input data. CONCLUSIONS This study demonstrated that there is a lack of systematization of the WPSD prescription process. The evaluation of the developed EasySeating app demonstrated that there is a potential to standardize, integrate and organize the WPSD prescription information, supporting and facilitating the decision making process of the prescribers. CLINICALTRIAL This study was approved by the Research Ethics Board of the Universidade de São Paulo (registered protocol n°53929516.6.0000.0065) URL - http://plataformabrasil.saude.gov.br/login.jsf

Lecture Courses

Three phases in Foucault’s examination of authorship and free speech were essential to him throughout his life. They can be linked to such texts as the three lectures “What is an Author?” (first phase), “What is Critique?,” and “What is Revolution?” (second phase), and the two lecture courses, “Fearless Speech,” and “The Courage of Truth” (third phase). Initially, Foucault merely describes the founders of discursivity (hence, “superauthors”), among whom he reckoned only Marx and Freud, as the sole alternative to his own conceptualization of the author function, which is exhibited en masse in contemporary society. He then modifies his views on superauthorship by making Kant the paradigm and by linking his own concept of free speech to a Kan-tian critical attitude. However, Foucault claims only the half of Kant’s philosophical legacy that is related to the study of the ontology of the self.The article advances the hypothesis that the sovereign power of speech, which can be found in Marx and Heidegger and in generally in the concept of “superauthorship,” becomes unacceptable for Foucault. During the third phase, the danger of a tyrannical use of free speech compels Foucault to make a number of fruitful but questionable choices in his work. He focuses on a single aspect of free speech in which a speaker is in a weaker position and therefore has to overcome his fear in order to tell the truth. Foucault associates this kind of free speech with the ancient Greek notion of parrhesia, which according to his interpretation means “fearless speech”; however, this reading is not always supported by the ancient Greek sources. Foucault’s deliberations bring him to the radical conclusion that free speech transforms into performative “aesthetics of existence.” Foucault’s main motivation for pursuing this line of thought all through his life was to investigate his own abilities and powers as an author
