Faktor-faktor Yang Berhubungan Dengan Kejadian Malaria Di Kecamatan Kabola, Kabupaten Alor, Provinsi Nusa Tenggara Timur (NTT) Tahun 2014

In last three years, Malaria cases in District Kabola was fluctuating. There was 414 Malaria cases in 2011, decreased into 107 in 2012, and increased into 327 in 2013. The aim of this study is to determine the relationship of people's behavior, socio-economic factors and the use of netting with the incidence of malaria in Kabola Village. This is an analytical research with cross - sectional design and 180 people were taken as a sample of 327 people. This research use probability sampling with Stratified Random Sampling method. Result showed that there is a relationship between education (p = 0,017), income (p = 0,007), knowledge (p = 0,016), attitude (p = 0,000), action (p = 0,012), and the use of mosquito nets (p = 0,021) with Malaria incidence. Meanwhile, occupation (p = 0,063) has nothing to do with Malaria incidence. In conclusion, Malaria incidence has relationship with education, income, knowledge, attitudes, actions, and the use of mosquito nets, while occupation has nothing to do with malaria incidence. It is recommended that health care providers (health centers, Pustu, Polindes, and Posyandu) have to give more information/ counseling about prevention, eradication, and malaria handling

Dynamic models for the analysis of epidemic spreads Modelli dinamici per l'analisi di diffusioni epidemiche

Quest'elaborato studia e analizza il modello SIR o di Kermack-McKendrick sulle diffusioni epidemiche svillupato nel 1927. In seguito vengono prese in considerazione diverse sue generalizzazioni per adattarlo a situazioni più complesse. Infine applichiamo il modello a dei reali focolai epidemici e ne valutiamo le simulazione tramite Matla

High-SIR Transmission Capacity of Wireless Networks with General Fading and Node Distribution

In many wireless systems, interference is the main performance-limiting factor, and is primarily dictated by the locations of concurrent transmitters. In many earlier works, the locations of the transmitters is often modeled as a Poisson point process for analytical tractability. While analytically convenient, the PPP only accurately models networks whose nodes are placed independently and use ALOHA as the channel access protocol, which preserves the independence. Correlations between transmitter locations in non-Poisson networks, which model intelligent access protocols, makes the outage analysis extremely difficult. In this paper, we take an alternative approach and focus on an asymptotic regime where the density of interferers $\eta$ goes to 0. We prove for general node distributions and fading statistics that the success probability \p \sim 1-\gamma \eta^{\kappa} for $\eta \rightarrow 0$, and provide values of $\gamma$ and $\kappa$ for a number of important special cases. We show that $\kappa$ is lower bounded by 1 and upper bounded by a value that depends on the path loss exponent and the fading. This new analytical framework is then used to characterize the transmission capacity of a very general class of networks, defined as the maximum spatial density of active links given an outage constraint.Comment: Submitted to IEEE Trans.

On the magnon interaction in Haematite. 2: Magnon energy of the acoustical mode and magnetic critical fields

Previous spin wave theories of the antiferromagnet hematite were extended. The behavior of thermodynamic quantities around the Morin transition temperature was studied, and the latent heat of the Morin transition was calculated. The temperature dependence of the antiferromagnetic resonance frequency and the parallel and perpendicular critical spin-flop magnetic fields were calculated. It was found that the theory agrees well with experiment

Enhancement of solar heavy nuclei at high energies in the 4 July 1974 event

Relative abundances of energetic nuclei in the 4 July 1974 solar event are presented. The results show a marked enhancement of abundances that systematically increase with nuclear charge numbers in the range of the observation, 6 less than or equal to Z less than or equal to 26 for energies above 15 MeV/nucleon. While such enhancements are commonly seen below 10 MeV/nucleon, most observations at higher energies are found to be consistent with solar system abundances. The energy spectrum of oxygen is observed to be significantly steeper than most other solar events studied in this energy region. It is proposed that these observations are characteristic of particle populations at energies approximately 1 MeV/nucleon, and that the anomalous features observed here may be the result of the high energy extension of such a population that is commonly masked by other processes or populations that might occur in larger solar events
