Nucleation Induced Undulative Instability in Thin Films of nCB Liquid Crystals

A surface instability is reported in thin nematic films of 5CB and 8CB, occurring near the nematic--isotropic phase transition. Although this instability leads to patterns reminiscent of spinodal dewetting, we show that it is actually based on a nucleation mechanism. Its characteristic wavelength does not depend markedly on film thickness, but strongly on the heating rate.Comment: 4 pages, 5 figure

Analisa Minyak Transformator Pada Transformator Tiga Fasa Di PT X

Tangen delta merupakan metoda diagnostik secara elektrikal untuk mengetahui kondisi isolasi. Salah satu isolasi yang perlu diketahui adalah minyak transformator yang merupakan isolasi cair. Pada sebuah transformator, isolasi merupakan bagian penting yang harus diketahui sejak awal sebagai referensi untuk mengetahui umur dari isolasi tersebut. Pada penelitian ini, untuk memastikan atau mengetahui pengaruh minyak transformator terhadap pengujian tangen delta. Pengujian dilakukan terhadap minyak transformator yang belum dilakukan filtering dan sesudah dilakukan filtering. Alat yang akan digunakan untuk pengujian tangen delta adalah Megger Delta 2000. Dari alat ini terdapat beberapa mode yang digunakan untuk pengujiannya yaitu GST, GSTg, dan UST

Non-Gaussian curvature distribution of actin-propelled biomimetric colloid trajectories

We analyze the motion of colloids propelled by a comet-like tail of polymerizing actin filaments. The curvature of the particle trajectories deviates strongly from a Gaussian distribution, implying that the underlying microscopic processes are fluctuating in a non-independent manner. Trajectories for beads of different size all showed the same non-Gaussian behavior, while the mean curvature decreased weakly with size. A stochastic simulation that includes nucleation, force-dependent dissociation, growth, and capping of filaments, shows that the non-Gaussian curvature distribution can be explained by a positive feedback mechanism in which attached chains under higher tension are more likely to sna

Effect of Family Support on Self Efficacy among Pregnant Women with Anemia

Background: As Albert Bandura has defined it, self-efficacy is an individual's belief in his or her innate ability to achieve goals. It is a personal judgment of how well one can execute courses of action required to deal with prospective situations. This study aimed to determine the effect of family support on self-efficacy among pregnant women with anemia to recover from anemia. Subjects and Method: This was a quasi-experiment before and after with no control design conducted at Puskesmas (community of health center) Gambirsari, Banjarsari, Surakarta, Central Java, from May to July 2018. A sample of 33 pregnant women with anemia was selected for this study. The dependent variable was self-efficacy to recover from anemia. The independent variable was family support through System Information of Self Treatment Anemia (SISTA) application. The data were collected by questionnaire and analyzed by chi square test. Results: Self-efficacy of pregnant women after family support (Mean= 15.70; SD= 2.44) was higher than before family support (Mean= 4.87; SD= 1.88), and it was statistically significant (p= 0.023). Conclusion: Family support via SISTA application is effective to help improve self-efficacy of pregnant women to recover from anemia. Keywords: family support, SISTA application, self-efficacy, pregnant wome

The Role of Electronic Worth of Mouth in Mediating TikTok Social Media Toward the Organizational Image of Universitas Muhammadiyah Ponorogo

The use of social media as a new medium in marketing has been considered quite effective. The users obtain plenty of marketing benefits through social media. TikTok social media has been recently famous amidst the society. This social media with a short video has the advantages to draw the attention of the viewers. The use of social media in marketing creates comments in the form of E-WOM which enables it to impact the image of an organization or company. This research uses a quantitative research method, taking 100 members of the campus tour of Universitas Muhammadiyah Ponorogo in 2021 as the sample. The marketing strategy using social media is executed by the technical implementation unit  of the new student admissions of Universitas Muhammadiyah Ponorogo by creating a short video uploaded in its Instagram account. The organizational image becomes a dependent variable of this research which will be tested by the use of TikTok as an independent variable and E-WOM as a mediator variable. The result of this research shows that E-WOM has a positive influence in mediating the impact of TikTok use toward the organizational image of Universitas Muhammadiyah Ponorogo.

Role of Religiosity in Moderating Factors Affecting Customer's Preference to Choose Financing

This study aims to examine the factor of religiosity as a moderator variable between the influence of production factors and economic potential on customer preferences in choosing to finance. The object is the customer of Baitul Mal Wat Tamwil (BMT) Khasanah Jabung Ponorogo, who has used financing products at such Islamic financial institutions. Quantitative methods are used to analyze the data, assisted by the Smart PLS application program. The result of this study indicates that religiosity strengthens the variables of product factors and economic potential in influencing customer preferences to choose to finance. Therefore, it is concluded that customers understand the benefits and blessings that will be obtained if you choose a sharia financial institution, which here is BMT Khasanah, as a partner in running its business
