Penelitian tindakan kelas yang berjudul Penerapan Metode Demonstrasi dapat Meningkatkan Hasil Belajar IPA pada Siswa Kelas IV SD Inpres I Sidole. Penelitian ini dilakukan dalam dua siklus, setiap siklus terdiri dari empat tahap yang mengacu pada model Kemmis dan Mc Taggart yaitu perencanaan, pelaksaan tindakan, observasi dan refleksi. Sumber data penelitian adalah siswa kelas IV SD Inpres 1 Sidole yanng berjumlah 15 orang. Pada penelitian ini data dikumpulkan melalui lembar observasi aktivitas guru dan siswa, tes hasil belajar siswa. Hasil penelitian menunjukkan bahwa aktivitas siswa dan guru mengalami peningkatan yang cukup berarti dari siklus I ke siklus II. Hasil ketuntasan klasikal pada siklus I adalah 66,67% dan daya serap klasikal adalah 69,2%. Hasil ketuntasan klasikal pada siklus II adalah 93.3% dan hasil presentase daya serap klasikal siklus II adalah 77,73%. Hal ini menunjukkan persentase peningkatan hasil belajar IPA dari siklus I ke siklus II pada ketuntasan klasikal sebesar 26,63% dan daya serpa klasikal sebesar 8.73%. Hasil penelitian ini menunjukan bahwa pembelajaran dengan penerapan metode demonstrasi dapat meningkatkan hasil belajar IPA siswa kelas IV SD Inpres I sidole

Responding to accents after experiencing interactive or mediated speech

Very little known is about how speakers learn about and/or respond to speech experienced without the possibility for interaction. This paper reports an experiment which considers the effects of two kinds of exposure to speech (interactive or non-interactive mediated) on Scottish English speakers’ responses to another accent (Southern British English), for two processing tasks, phonological awareness and speech production. Only marginal group effects are found according to exposure type. The main findings show a difference between subjects according to exposure type before exposure, and individual shifts in responses to speech according to exposure type

Dynamic hysteresis in Finemet thin films

We performed a series of dynamic hysteresis measurements on three series of Finemet films with composition Fe$_{73.5}$Cu$_1$Nb$_3$Si$_13.5$B$_9$, using both the longitudinal magneto-optical Kerr effect (MOKE) and the inductive fluxometric method. The MOKE dynamic hysteresis loops show a more marked variability with the frequency than the inductive ones, while both measurements show a similar dependence on the square root of frequency. We analyze these results in the frame of a simple domain wall depinning model, which accounts for the general behavior of the data.Comment: 3 pages, 3 figure

Fixed combination of lercanidipine and enalapril in the management of hypertension: focus on patient preference and adherence.

Hypertension is one of the most important and widespread risk factors for the development of cardiovascular disease. Once, combination therapy was traditionally reserved as a third-line or fourth-line approach in the management of hypertension. However, several major intervention trials in high-risk patient populations have shown that an average of 2-4 antihypertensive agents are required to achieve effective blood pressure control. Combination treatment should be considered as a first choice in patients at high cardiovascular risk and in individuals for whom blood pressure is markedly above the hypertension threshold (eg, more than 20 mmHg systolic or 10 mmHg diastolic), or when milder degrees of blood pressure elevation are associated with multiple risk factors, subclinical organ damage, diabetes, renal failure, or associated cardiovascular disease. A number of clinical trials have demonstrated that a fixed combination of lercanidipine and enalapril has better efficacy and tolerability than monotherapy with either agents. The fixed-dose formulation of lercanidipine-enalapril was well tolerated in all clinical trials, with an adverse event rate similar to that of the component drugs as monotherapy. The advantages of combination therapy include improved adherence to therapy and minimization of blood pressure variability. In addition, combining two antihypertensive agents with different mechanisms of action may provide greater protection against major cardiovascular events and the development of end-organ damage

Application of track-before-detect techniques in GNSS-based passive radar for maritime surveillance

GNSS-based passive radar has been recently proved able to enable moving target detection in maritime surveillance applications. The main restriction lies in the low Equivalent Isotropic Radiated Power (EIRP) level of navigation satellites. Extending the integration times with proper target motion compensation has been shown to be a viable solution to improve ship detectability, but this involves computational complexity and increasing sensitivity to motion model mismatches. In this work, we consider the application of a Track-Before-Detect (TBD) method to considerably increase the integration time (and therefore the detection capability) at the same time keeping the computational complexity affordable by practical systems. Dynamic programming TBD algorithms have been specialized for the considered framework and tested against experimental dataset. The obtained results show the effectiveness of this approach to improve the detection capability of the system despite the restricted power budget
