Background: Beginning in 2015, subcutaneous depot medroxyprogesterone acetate (DMPA-SC) was added to the contraceptive method mix in Nigeria, primarily through social marketing in the private sector and community-based distribution in the public sector. We compare user experiences in acquiring DMPA-SC across sectors during this national scale-up. Methods: From October 2017 to February 2018, 459 women (Npublic=235; Nprivate=224) completed a phone survey from a convenience sample of 1,444 women (Npublic=912; Nprivate=532) who obtained DMPA-SC from participating providers and agreed to be contacted. We examined the sociodemographic predictors of attending a public vs. private provider and analyzed differences in care-seeking across sectors (becoming aware of DMPA-SC, choosing a provider, choosing DMPA-SC, quality of care). Results: Respondents obtaining DMPA-SC from public providers were younger and less educated than those attending private providers. Both program respondents were comprised of similar percentages of new users of modern contraception (58.7-60.3%), although most respondents became aware of DMPA-SC through a friend/family member (43.1%) or a provider (41.5%). Relatively more public sector respondents also heard about DMPA-SC through community outreaches whereas relatively more private sector respondents became aware through media. Convenience was the most common reason for choosing a provider—43.8% among all respondents (higher among public sector respondents). Private sector respondents were also more likely to choose a past or usual provider. Having overall higher quality interactions were more likely among clients who attended private providers than public providers, but responses to individual quality item measures show specific areas of poor quality for providers in each sector. Conclusions: Training emphasizing technical thoroughness, sensitivity toward younger women, and client choice may help improve women’s experiences with obtaining DMPA-SC, ultimately contributing to accelerating demand for and uptake of DMPA-SC specifically and contraception in general.
Historia instantánea. El nuevo impulso historiográfico francés --o historia mundial en los tiempos de Twitter
Authors: Conversi Daniele 
Published: December 2018

Resumen En la Histoire mondiale de la France editada por Patrick Boucheron (2017), la noción de una identidad francesa fija y primordial ha sido desafiada por una nueva generación de historiadores donde una historia ‘cruzada’, ‘interconectada’, y vocacionalmente global, permanece al mismo tiempo anclada en lo nacional. La secuencia cronológica desentierra una red de narrativas nacionales, co-nacionales y transnacionales canalizadas por la creatividad, la curiosidad y una amplia visión, como destellos en el firmamento del tiempo que ayudan a irradiar la oscura noche de las historiografías "nacionalizadas". El trabajo de Boucheron presenta todo lo contrario de los predecibles tratados repletos de Grandes Hombres y Grandes Eventos. Con su emblemático simbolismo cronológico, la novedad no reside tanto en un nuevo giro metodológico, cuanto en un cambio de paradigma presentacional, sin la pretensión de descubrir un lienzo más amplio dentro de una narrativa fluida y continuada. Lo que hace la novedad es, en cambio, el hilo de diferentes tramas e historias, sin sucumbir a la tentación de moldear un crisol de narrativas idiosincrásicas. Por lo tanto, la historia de Francia se convierte en una encrucijada de encuentros, una confluencia de casualidades, señalando al mismo tiempo los límites de la deconstrucción en la historia contemporánea —justo cuando esta ha alcanzado sus límites externos con demasiada facilidad y de forma normalizada. Si las deconstrucciones, aunque pedantes y tediosas, pueden ser apropiadas para deconstruir arbitrariamente hechos reales como si fueran ‘noticias falsas’, no es ya suficiente deconstruir la narrativa patriótica. Y si la deconstrucción se puede derivar en la construcción arbitraria, el deconstructivismo se deconstruye a sí mismo. Superando el constructivismo y el deconstruccionismo se intenta así producir una nueva 'historia instantánea'. De esta forma, podemos gozar de nuevas formas de re-concebir la reconfiguración de la misma identidad nacional en un sentido mas internacional, con la elección de instantes o movimiento de cambiamentos simbólicos, culturales y políticos que imparten su huella a través de las generaciones.

Published: December 2018

Maximum power point tracking (MPPT) is a technique to maximize the power output of photovoltaic (PV). Therefore, to achieve higher PV efficiency, the development of MPPT control algorithm is necessary. Recently, it was revealed that fuzzy logic controller (FLC) is better than other control algorithms and is possible toe developed. This study fabricated and implemented MPPT based on the proposed a new FLC. Input Calculator (IC) via sensors reads current and voltage of PV and generates the comparison of voltage and current of PV, then IC output becomes fuzzy algorithm input. Fuzzy algorithm produces duty cycle that drives synchronous buck converter. The result showed that MPPT system with proposed FLC method has 99.1% efficiency while MPPT system with P8O method has 95.5% efficiency. From the obtained result, it can be concluded that the MPPT based on the proposed FLC can increase the overall efficiency of the system to 99.3%.

Published: December 2018

Radar signal generator is a critical component in radar system as it determines the best achievable resolution. Single chip Fractional-N PLL synthesizer with built-in VCO and sweep modulator become more popular as Frequency Modulated Continuous Wave (FMCW) signal generator due to the simplicity and overall cost reduction. This paper presents a realization process and experimental result of dual-mode modulation pattern FMCW signal generator using HMC769LP6CE PLL. The PLL is controlled by ATMega328 microcontroller and Altera EPM240T100C5 CPLD to operate in two difference mode: 1-way sweep mode and 2-way sweep mode. The PLL is programmed with four different sweep bandwidth from 6.75–54 MHz for different range and resolution radar purpose. The performance of FMCW signal generator is measured using the output of passband signal spectrum. The experimental results indicate that the PLL-VCO with 2-way sweep mode has clearer frequency passband compared to 1-way sweep mode.

Published: December 2018

Radar imaging system is strongly influenced by other supporting systems. There is a motor system that provides angular information to the display system, and Digital Signal Processing (DSP) system that provides the main information for radar imaging. The new approach, we substitute a DC servo motor with a DC stepper motor as radar antenna rotator in our navigation radar system development. Different from the use of servo motors that can provide angle movements smoothly, the new motor system provides angle information of 0.56 degrees in every step, results in empty pixel gaps in every 0.56 degrees in radar Plan Position Indicator (PPI) image. The width of the empty pixel gaps becomes wider when the cell array of raw data is increasing regarding the image plotting process. In this paper, we proposed a new morphological dilation method to the radar raw data based on binary template matching to accommodate the various width of empty pixel gaps before the radar raw data are plotted into the radar PPI image. By this method, the morphological dilation will only be applied to the raw data that meet the same criteria as the binary template. Otherwise, the raw data will be left as they are. The result shows that there is 150.52% pixel data addition in the empty pixel gaps from the original image, and 48.44% increase of the morphological dilation without binary template matching method.

Selulosa merupakan polimer yang dihasilkan oleh makhluk hidup terutama tumbuh-tumbuhan dengan jumlah yang sangat besar, dan sebagian besar menjadi limbah, seperti limbah pertanian, kehutanan dan sampah kota.Limbah tersebut selama ini belum termanfaatkan dengan baik. Biasanya dipakai sebagai bahan bakar dengan nilai kalor yang rendah. Penguraian limbah TKKS akan didapatkan bermacam-macam zat kimia yang mempunyai nilai lebih seperti glukosa, asam levulinat, erithosa dan bahan bakar cair dan gas. Proses hidrotermal mampu menguraikan limbah TKKSmenjadi molekul kecil sebagai bahan bakar cair dan gas. Hidrotermal menggunakan media air yang berfungsi sebagaipelarut dan reaktan. Peruraian limbah TKKS dipengaruhi oleh kondisi operasi (tekanan, temperatur), jenis katalis, waktu reaksi, pengadukan dan rasio air dan padatan.Reaksi yang terjadi pada proses hidrotermal meliputi reaksi liquefaction, hydrolisis, dehydration, decarboxylation, condensation, aromatization dan polimerization.

Translation is process of transferring text from source language (SL) into target language (TL). The process can be challenging when there are no translation found on the TL as a result of different politics, economy, social, cultural, historical and religious backgrounds. A text containing folklore is one of the difficult texts to be translated as it contains legend, tradition, art or folktale. When untranslability happens, Venuti (2000: 427) suggests translator to use the original text by adding footnote or glossary. To avoid a shift in translation, Vinay and Dalbernet (1958) suggests two translation methods namely direct translation along with three translation techniques, these are Calque, and literal translation and oblique methods along with four translation techniques named transposition, modulation, equivalence or reformulation, and adaptation. This research applies those model, methods and techniques of translation along with folklore research method from Dundes (2007) to promote tourism at Pekalongan Regency area.

Abstract
In the current study is to examine numerically the effects of presence of a radial magnetic field, slip and jump conditions on the steady two-dimensional free convective boundary layer flow over an external surface of a vertical cone for an electro-conductive polymer. A proper non-similarity transformation simplifies the system of partial differential equations into a system of ordinary differential equations. The collocation formula in the MATLAB software then solves the system of non-similarity equations. The finding results show that, a weak elevation in temperature is accompanied with the increase in the Carreau fluid parameter, whereas a significant acceleration in the flow is computed near the cone surface. The study is relevant to smart coating transport phenomena.
The nonlocal boundary problem with perturbations of antiperiodicity conditions for the eliptic equation with constant coefficients
Authors: Baranetskij Ya.O. , Ivasiuk I.Ya. , Kalenyuk P.I. , Solomko A.V. 
Published: December 2018

In this article, we investigate a problem with nonlocal boundary conditions which are perturbations of antiperiodical conditions in bounded $m$-dimensional parallelepiped using Fourier method. We describe properties of a transformation operator $R:L_2(G) \to L_2(G),$ which gives us a connection between selfadjoint operator $L_0$ of the problem with antiperiodical conditions and operator $L$ of perturbation of the nonlocal problem $RL_0=LR.$
Also we construct a commutative group of transformation operators $\Gamma(L_0).$ We show that some abstract nonlocal problem corresponds to any transformation operator $R \in \Gamma(L_0):L_2(G) \to L_2(G)$ and vice versa. We construct a system $V(L)$ of root functions of operator $L,$ which consists of infinite number of adjoint functions. Also we define conditions under which the system $V(L)$ is total and minimal in the space $L_{2}(G),$ and conditions under which it is a Riesz basis in the space $L_{2}(G)$.
In case if $V(L)$ is a Riesz basis in the space $L_{2}(G),$ we obtain sufficient conditions under which the nonlocal problem has a unique solution in the form of Fourier series by system $V(L).$
Application of duality theory to solve two-criteria problem of linear programming for ecological-economic system
Authors: Khrushch L.Z. 
Published: December 2018

In the paper, we investigate two-criterion optimization problem: maximization of one target function and minimization of another target function. To solve the offered two-criterion problem, the method of the main criterion is applied. We consider the problem of production activity of the ecological-economic system with the maximization of the value of the final product as the first target function and the minimization of emissions of polluters into the environment as the second target function. We constructed of two production functions (economic and ecological). To construct the economic production function, we select maximal producing of the final products in a costing form as the most essential (main) criterion. Also, there is introduced the appropriate data of the criterion level total volume of emissions of polluters into the environment. After this two-criteria problem is reduced to one-criteria problem. For the construction of ecological production function, the main criterion in the problem of the minimal general volume of emissions of polluters into the environment is defined. We use a parameter of the criterion level of the second criterion and obtained one-criterion problem. Therefore, investigation of the appropriate dual problems explicitly provides economic and ecological production functions to the deduced one-criterion problems. These functions in input two-criterion problem give way to optimal manage of ecological-economic system.
