Infância livre, memória e documentário

"Tempos de bairro" explora o desaparecimento de um hábito infantil que era comum em gerações anteriores. Baseado nas memórias de uma infância pessoal, o documentário mostra um período de outrora onde as brincadeiras de rua formavam a paisagem de um bairro. Como tal, ao longo deste trabalho faz-se a revisitação de um passado e relata-se a experiência de um lugar. Evocam-se memórias e questiona-se o desaparecimento dessa 'tradição' infantil. Numa outra dimensão, este projecto é desenvolvido envolta da memória onde há, primeiramente, uma abordagem pessoal sobre as memórias de uma infância e, de seguida, uma procura por alternativas ao uso de material de arquivo. Por este revelar-se insuficiente, expõem-se algumas estratégias de representação dentro e fora do documentário como forma de retratar um tempo passado e de envolver o espectador na história. Com este projecto e a realização deste documentário pretende-se que o espectador se identifique com a temática e que, posteriormente, reconheça o valor dos espaços exteriores como um meio de exploração e de conhecimento do mundo para a infância."Neighborhood's Times" explores the disappearance of a childhood's habit which was common among previous generations. Based on personnal childhood memories, this documentary shows a period where playing in the street was a normal portrait of a neighborhood. As such, throughout this work I revisit a past and report the experience of a place. Memories are evoked and after It questions the disappearance of this childhood 'tradition'. On another dimension, this project is developed around the memory where there is first an personnal approach about childhood memories and then a search for alternatives to the use of archival material. As this one was insufficient, some strategies of representation inside and outside the documentary film are shown in order to describe a past time and to involve the spectator into the story. Through this project and documentary, I intend that the spectator can involve and identify himself into the subject, recognizing afterwards the value of outdoor spaces benefits as a way of exploration and knowledge to a child's world

Takayasu’s arteritis in pregnancy

We had the opportunity to manage a pregnant lady who presented for the first time at 34 weeks of amenorrhea with absent pulses in upper limbs on examination. She underwent Magnetic Resonance Angiography to confirm the diagnosis of Takayasu’s arteritis. Luckily she did not have complications of Takayasu’s such as hypertension, cardiac failure, neurological symptoms, visual disturbances. She proceeded to have a normal vaginal delivery after aggressive management which included a multidisciplinary team involving obstetrician, cardiologist, physician and rheumatologist

The relationship between generic strategies and organizational performance: A study of furniture companies in Kurdistan

The main purpose of this research is to examine the relationship between generic strategies and organizational performance in selected furniture companies in Kurdistan.The researcher used quantitative research method to analyze the relationship between generic strategies and organizational performance of furniture companies in Kurdistan. The researcher printed and distributed 100 questionnaires, but received only 76 questionnaires from participants. Accordingly the sample size of this study is 76 unitsThe findings of this study revealed that the three generic strategies (cost strategy, differentiation strategy and focus strategy) have positive relationship with organizational performance in selected furniture companies in Kurdistan. A research could be completed in different businesses to see if similar outcomes will be gotten. This research likewise recommends that an exploration study could be done to decide factors impacting successful execution of effective strategy in the busines

PRES in pregnancy: MRI and it's role in decision making

Posterior reversible encephalopathy syndrome (PRES) is an alarming clinic-neuro-radiological syndrome accompanying various clinical conditions, presenting with headache, encephalopathy, seizures, cortical visual disturbances or blindness. The lesions in PRES are thought to be due to vasogenic oedema, predominantly in the water-shed regions of the posterior cerebral hemisphere, fortunately, completely reversible with management of the primary condition. We report a case of primigravida with 26 weeks pregnancy, who presented with acute, severe, in-tractable, throbbing headache, tingling sensation in the posterior neck and upper shoulder region, photophobia, nausea and mild pre-eclampsia. Standard therapy did not relieve the headache, BP remained fluctuant, so migraine/some intra-cranial pathology was suspected. MRI is the gold-standard diagnostic modality. It revealed the classical acute PRES picture. PRES implies breaching of the blood brain barrier, resultant cerebral edema and potential for further intra-cranial events of serious proportions. Notably, PRES may be seen with normotension. Pregnancy was terminated un-eventfully, recovery was prompt and complete. Two weeks later, the patients showed marked improvement clinically and neuro-imaging features of PRES had dis-appeared

Drug Resistance of Acinetobacter in Selected Hospitals

Background: Nowadays, nosocomial infection with multidrug-resistant Acinetobacter is an important problem in the world, which is facing wide spectrum antibiotics and hence has become resistant.Materials and Methods: In this study, positive cultures of Acinetobacter from one hundred clinical samples in seven hospitals from Tehran during 2012-2013 were collected for checking antibiotic susceptibility. Samples test with Ceftazidim, Cefepime, Amikacine and Imipenem by E-test and for Tazocin, Colistin and Tigecycline was performed with disk diffusion method.Results: For Colistin 10 samples, and for Tazocin, 40 samples were performed by E-test method. Then boumannii species of bacteria and non-baumannii Acinetobacter were separated by PCR and antibiotic susceptibility testing was performed on them. 89% of Acinetobacter samples were boumannii species, which was isolated from respiratory secretions at ICU.Conclusion: Boumannii and non-boumannii species of bacteria with a high percentage were resistant to Ceftazidim, Amikacine, Cefepime, Tazocin and Imipenem. All baumannii and non-boumannii Acinetobacter were sensitive to Colistin, were only 75% sensitive to Tigecycline, which is a new glycylcycline. Colistin and Tazocin results in samples limited to the E-test method were similar with disk diffusion

Sleep Mode Analysis via Workload Decomposition

The goal of this paper is to establish a general approach for analyzing queueing models with repeated inhomogeneous vacations. Theserver goes on for a vacation if the inactivity prolongs more than a vacation trigger duration. Once the system enters in vacation mode,it may continue for several consecutive vacation. At the end of a vacation, the server goes on another vacation, possibly with a {\emdifferent} probability distribution, if during the previous vacation there have been no arrivals. However the system enters in vacationmode only if the inactivity is persisted beyond a defined trigger duration. In order to get an insight on the influence of parameterson the performance, we choose to study a simple $M/G/1$ queue (Poisson arrivals and general independent service times) which hasthe advantage of being tractable analytically. The theoretical model is applied to the problem of power saving for mobile devices inwhich the sleep durations of a device correspond to the vacations of the server. Various system performance metrics such as the frameresponse time and the economy of energy are derived. A constrained optimization problem is formulated to maximize the economy of energy achieved in power save mode, with constraints as QoS conditions to be met. An illustration of the proposed methods is shown with a WiMAX system scenario to obtain design parameters for better performance. Our analysis allows us not only to optimize the system parameters for a given traffic intensity but also to propose parameters that provide the best performance under worst caseconditions

Vacation Policy Optimization with Application to IEEE 802.16e Power Saving Mechanism

Much research has been devoted to optimizing the power saving mechanism in wireless mobile devices. Recent advances in wireless radio technology facilitate the implementation of various possible sleep policies. One basic question that arises is: which policy performs best under a certain condition? Furthermore, what are the optimal parameters for a given policy? To answer these questions, we formulate an optimization problem, which entails cost minimization for a given parameterized policy and selection of the best policy among a class. We propose a cost function which captures the inherent tradeoff of delay and energy saving. This takes into account the cost of response time due to the extra sleep, the energy saving during the sleep, and the cost for periodic waking up (for listening). As an application, we consider IEEE 802.16e's power saving mechanism. We study various practical policies and check their performance. We show that the constant duration policy is optimal for Poisson inactivity periods, but not for hyper-exponentially distributed inactivity periods. In the policy where vacations are i.i.d. exponential random variables, we derive analytically the optimal control as a function of the expected inactivity period. This result holds for general inactivity periods. Our framework allows us to compare the performance of several optimal and suboptimal practical policies with that of the IEEE 802.16e standard

Systemic signaling during abiotic stress combination in plants

Article reveals that plants can integrate different local and systemic signals generated during conditions of stress combination. Furthermore, results show that the specific part at which plants sense the two co-occurring stresses makes a significant difference in how fast and efficient they acclimate
