Axial electrokinetic trapping of single particles at kHz feedback rates

Anti-Brownian Electrokinetic (ABEL) trapping has proven to be a valuable novel tool for analysis at the single-nanoparticle level. In previous work, we explored axial (in the z-direction only) ABEL trapping with planar ITO electrodes based on video image analysis. In this work, we improved the method by using total-internal-reflection (TIR) in combination with a single-photon-counting module. This allows us to axially trap single nanoparticles with a homogeneous field at feedback rates of several kHz such that screening of the electric field becomes negligible

Terapi Story Telling dan Menonton Animasi Kartun terhadap Ansietas

This study aims to determine the comparison of the effectiveness of story telling therapy and watching animated cartoons on the level of anxiety due to hospitalization in preschool aged children at the hospital. Raflesia Bengkulu City. This study used a quasi experimental design of two groups before after or pre-test and post test group. The results showed that the treatment using story telling (storytelling) was more significant in reducing anxiety in pre-school age children at Raflesia Hospital, Bengkulu City compared to watching cartoon animation, seen from the value of the t-test results of the Independent sample, the mean value of posttest results was 5. between story telling therapy and watching cartoon animation, namely 2.00 and 8.00. In conclusion, story telling is six times faster to reduce anxiety (anxiety) in pre-school children during hospitalization compared to watching cartoon animation therapy.   Keywords: Cartoon Animation, Anxiety, Pre School, Story Tellin

Electrokinetic trapping of non-fluorescent nanoparticles in water

Anti-Brownian electrokinetic trapping enables the confinement of single nanoparticles in solution by applying feedback electric forces that counteract Brownian motion. This technique facilitates the long-term observation of nanoparticles to study their different physio- and bio- chemical properties. However, the method has been greatly restricted to nanoparticles that can be visualized by photoluminescence. In this work, we demonstrate the electrokinetic trapping of fluorescence-free nanoparticles that scatter the evanescent field induced by total internal reflection (a). Using the measured intensity of scattered photons (b) as a feedback, we generate an external electric field (c) that holds the particle at the desired distance from the glass surface. As a result, we are able to trap the nanoparticle and trace its response to the applied voltage (d) at kilohertz rates without any fluorescent labeling. Our approach significantly extends the range of nanoobjects that can be trapped at the single-particle level in an aqueous solution based purely on their light-scattering properties

Dinamika Komunikasi Keluarga di Tengah Isu Pandemi Covid-19

Berbicara mengenai isu pandemic Covid- 19 sama artinya dengan berbicara masalah kita semua artinya setiap orang  akan merasakan imbas dari isu pandemik ini baik secara langsung maupun tidak langsung bahkan setelah memasuki tahun ke-II ditahun 2021 ini belumlah virus Corona ini berakhir. Ketika setiap warga pergi harus menggunakan masker, harus menjaga jarak agar tidak menciptakan kerumunan, pembatasan jumlah orang dalam penyelenggaraan acara, harus mengikuti sejumlah protokol kesehatan dan sejumlah aturan lainnya menggambarkan bahwa virus Covid-19 ini tidak lah hanya berimbas kepada satu isu kesehatan saja namun masih memiliki ragam rentetan selanjutnya  kepada isu lainnya baik isu ekonomi bisnis, isu pendidikan, isu social, isu kriminal serta isu lainnya. Namun dari segala isu yang ada ini penulis hanya ingin fokus menyorot dampak bagi manusia itu sendiri yang menjadi “korban” dari Covid-19 ini terutama yang telah menyerang aspek psikologis mereka baik mereka yang pernah menjadi pasien Covid-19, mereka yang terkena imbas ekonomi sehingga harus kehilangan pekerjaan bahkan mereka yang harus kehilangan orang-orang yang mereka cintai akibat serangan virus ini. Penulis ingin menyorotinya dari peran kehadiran keluarga, orang-orang terdekat untuk menguatkan para “korban” Covid -19 ini agar mereka tetap semangat, tidak mudah mengeluh, ikhlas menerima segala ketentuan Allah Swt yang disajikan dari sudut peran Komunikasi Keluarga yang memiliki banyak dinamika di tengah isu Covid -19 ini

Positive anymore in American English

Positive anymore in American English (Language of the TFG: English) Abstract: The use of anymore that is more widespread in the English-speaking world is the negative one, that is, an adverb that co-occurs with some negative expression in the clause. However, in some parts of the English-speaking world, anymore is also used in non-negative linguistic contexts. This positive usage of the word anymore that is usually restricted to negative environments has been the focus of study of many researchers. From its meaning to the restrictions that operate on its use, to the socio-cultural distribution, to the way it may evolve in the future, different hypotheses have been proposed through the years. Nevertheless, the random responses given by participants have made it difficult for researchers to validate hypotheses about this non-mainstream usage. This study aims to analyze those hypotheses. First, I examine negation in English and what concerns to the usage of negative anymore. Second, I introduce positive anymore and the two main issues that have been studied about it: different interpretations of positive anymore (i.e. nowadays, lately and from now on) and the debate among linguists on whether there is one unique pan-dialectal anymore or we are talking about two different lexical items. In other words, whether the anymore used in negative and positive sentences is the same lexical item and only differs in meaning and the restrictions that operate on its use depending on the context or, on the contrary, they are independent lexical items with different meanings and restrictions operating on its use. Third, this study analyzes the conditions on the use of positive anymore: its syntactic distribution as well as its semantic conditions. Fourth, the current usage of positive anymore is tackled and, finally, this paper has a look at other non-mainstream constructions to some extent similar to positive anymore. There are still many sides of positive anymore to be researched and hypotheses to be verified and accepted. For future studies it would be interesting to keep an eye on positive anymore as the course of this lexical element is still unknown. Whether it will undergo any changes in the future and whether it will settle and spread towards more areas in the U.S. or it will disappear for good is yet to be seen
