Densitas Asupan Energi dan Status Gizi serta Hubungannya dengan Perkembangan pada Anak Usia Prasekolah

Usia prasekolah merupakan usia dimana anak mengalami masa keemasan (golden age). Periode ini merupakan periode terpenting bagi anak, dikarenakan kebutuhan gizi atau status gizi anak akan mempengaruhi perkembangan anak. Tujuan dari penelitian ini adalah mengkaji densitas energi dan status gizi, serta hubungannya dengan perkembangan anak usia prasekolah yaitu perkembangan motorik kasar, motorik halus, kemampuan bicara dan bahasa, serta sosialisasi dan kemandirian. Metode penelitian ini adalah penelitian kuantitatif dengan desain penelitian adalah cross sectional. Lokasi penelitian ini berada di TK Laboratorium Kristen Satya Wacana, Kecamatan Sidorejo, Kota Salatiga, Jawa Tengah. Sampel yang digunakan dalam penelitian ini adalah 40 anak. Analisis data pada penelitian ini menggunakan analisis univariat dan analisis bivariat. Berdasarkan hasil penelitian ini menunjukkan bahwa sebagian besar subjek anak perempuan yang berada pada usia 36 – 59 bulan dengan seluruh subjek penelitian mengkonsumsi makanan dengan densitas energi yang tinggi. Tinggi dan rendahnya nilai densitas energi pada anak prasekolah ini harus diseimbangkan dengan nilai zat gizi mikro lainnya untuk menunjukkan konsumsi makanan anak usia prasekolah yang baik. Densitas energi signifikan berhubungan dan berkorelasi positif dengan aspek spesifik perkembangan bicara dan bahasa. Status gizi signifikan berhubungan dan berkorelasi negatif dengan aspek spesifik perkembangan anak dalam motorik kasar. Peneliti lain dapat menganalisis lebih lanjut terkait densitas gizi pada anak, terutama pada zat gizi mikro yang dapat mempengaruhi pertumbuhan dan perkembangan anak.Preschool age is the age where children experience the golden age. This period is the most important period for children, because the child's nutritional needs or nutritional status will influence the child's development. The aim of this research is to examine energy density and nutritional status, as well as their relationship with the development of preschool children, namely the development of gross motor skills, fine motor skills, speech and language skills, as well as socialization and independence. This research method is quantitative research with a cross sectional research design. The location of this research is at the Satya Wacana Christian Laboratory Kindergarten, Sidorejo District, Salatiga City, Central Java. The sample used in this research was 40 children. Data analysis in this study used univariate analysis and bivariate analysis. Based on the results of this study, it shows that the majority of female subjects aged 36 - 59 months with all research subjects consuming foods with high energy density. High and low energy density values in preschool children must be balanced with other micronutrient values to indicate good food consumption for preschool children. Energy density is significantly related and positively correlated with specific aspects of speech and language development. Nutritional status is significantly related and negatively correlated with specific aspects of children's development in gross motor skills. Other researchers can analyze further regarding nutritional density in children, especially micronutrients which can influence children's growth and development.

Prospects for K+→π+ννˉK^+ \to \pi^+ \nu \bar{ \nu } at CERN in NA62

The NA62 experiment will begin taking data in 2015. Its primary purpose is a 10% measurement of the branching ratio of the ultrarare kaon decay $K^+ \to \pi^+ \nu \bar{ \nu }$, using the decay in flight of kaons in an unseparated beam with momentum 75 GeV/c.The detector and analysis technique are described here.Comment: 8 pages for proceedings of 50 Years of CP

Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR

Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials (mu_B > 500 MeV), effects of chiral symmetry, and the equation-of-state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2022, in the context of the worldwide efforts to explore high-density QCD matter.Comment: 15 pages, 11 figures.

Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV

First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on {\pi}+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.Comment: 29 pages, 20 figure

Externalities and the nucleolus

In most economic applications, externalities prevail: the worth of a coalition depends on how the other players are organized. We show that there is a unique natural way of extending the nucleolus from (coalitional) games without externalities to games with externalities. This is in contrast to the Shapley value and the core for which many different extensions have been proposed

The beam and detector of the NA62 experiment at CERN

NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the K+ → π+ ν bar nu decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions. For this purpose, innovative techniques have been developed, in particular, in the domain of low-mass tracking devices. Detector construction spanned several years from 2009 to 2014. The collaboration started detector commissioning in 2014 and will collect data until the end of 2018. The beam line and detector components are described together with their early performance obtained from 2014 and 2015 data

Noise measurements on Si sensors

Developing silicon strip sensors for the CMS Preshower detector we have noticed that some strips have a noise higher than the average and not correlated to a high leakage current. In order to investigate this effect we have developed a set-up for noise measurement on wafers and diced sensors that does not require bonding. The set-up is based on the DeltaStream chip coupled to a probe card. We have tested 45 sensors and found that the strips with an above average noise have a higher relative current increase as a function of voltage, DeltaI /(IDeltaV). We also observed that, on these strips, the breakdown occurs within about 60 V from the voltage at which the noise is observed. We describe our measurement method and present the results
