Explaining the Effect of Surrounding Pressure on Splashing Phenomena of Liquid Drop using Statistical Mechanics
Authors: Ali Muhammad
Published: October 2019

This paper explains the effect of surrounding gas pressure on splashing phenomena of liquid drop using fixed volume canonical ensemble of gas at high pressure and liquid. The energy state fluctuations in liquid drop energy (𝐸_𝐿) are given by exponential probability distribution at high pressures. High pressure increases the translational components of the kinetic energy which are not normal to the drop surface. This corresponds to higher range of incidence angles, which controls the impact outcome. Furthermore, Surface coverage of liquid molecules (𝜃_𝑙𝑖𝑞) by adsorption process is derived, which is the function of surrounding gas pressure 𝑝. High pressure decreases the surface coverage of liquid molecules making the liquid drop more vulnerable for splashing.
Musa Tidak Diperkenankan Memasuki Tanah Perjanjian (Analisis Perspektif Ulangan)
Authors: Tobing Oscard L
Published: October 2019

Why Moses could not enter the promised land? He was chosen to deliver Israelites from rough slavery in Egypt. He led them for 40 years until arriving at Canaan. Unfortunately, he did not enter the land. On occasion of this problem, there are two traditions from different dating authorship with a different set of argumentation. In the history of Israel, the greatness dan magnificence of Moses extremely influenced Deuteronomistic’s author in proposing a reason why Moses was prohibited by the LORD to enter the land of Canaan. This perspective is inversely proportional to Priestly writings. The Israelites' sin caused Moses to see the land only from a distance, the top of Pisgah

Published: October 2019

To valorize the underutilized nipa sap composed mainly of sucrose, glucose and fructose, acetic acid fermentation by Moorella thermoacetica was explored. Given that M. thermoacetica cannot directly metabolize sucrose, we evaluated various catalysts for the hydrolysis of this material. Oxalic acid and invertase exhibited high levels of activity towards the hydrolysis of the sucrose in nipa sap to glucose and fructose. Although these two methods consumed similar levels of energy for the hydrolysis of sucrose, oxalic acid was found to be more cost-effective. Nipa saps hydrolyzed by these two catalysts were also fermented by M. thermoacetica. The results revealed that the two hydrolyzed sap mixtures gave 10.0 g/L of acetic acid from the 10.2 g/L of substrate sugars in nipa sap. Notably, the results showed that the oxalic acid catalyst was also fermented to acetic acid, which avoided the need to remove the catalyst from the product stream. Taken together, these results show that oxalic acid hydrolysis is superior to enzymatic hydrolysis for the pretreatment of nipa sap. The acetic acid yield achieved in this study corresponds to a conversion efficiency of 98%, which is about 3.6 times higher than that achieved using the traditional methods. The process developed in this study therefore has high potential as a green biorefinery process for the efficient conversion of sucrose-containing nipa sap to bio-derived acetic acid.

Authors: Shoda Badris
Published: October 2019

Penyediaan pakan yang memadai dalam peternakan unggas sangat menunjang keberhasilan usaha. Pakan merupakan semua bahan yang dapat dimakan ternak, dicerna, diserap dan juga dapat dipergunakan untuk memenuhi kebutuhannya. Untuk meningkatkan pertumbuhan broiler banyak peternak percaya bahwa produksi ternak hampir tidak mungkin berhasil tanpa penggunaan antibiotik sebagai pemacu pertumbuhan (Antibiotic Growth Promotor). Adanya dampak negatif dan dilarangnya penggunaan AGP, pakan yang ada sekarang tidak bisa menunjang pertumbuhan broiler sesuai dengan potensinya, maka dicarilah alternatif lain yang berbahan dasar organik salah satunya menggunakan supplement pada daun mengkudu.Kegiatan Proyek Usaha Mandiri dilaksanakan di kandang broiler UPT Farm Politeknik Pertanian Negeri Payakumbuh pada tanggal 26 Februari 2019 sampai tanggal 14 Mei 2019. Alat yang digunakan dalam pelaksanaan pemeliharaan ayam tersebut adalah tempat pakan, tempat minum, piting lampu, bola lampu, ember, tirai plastik, timbangan, kabel, kuas, sapi lidi, pisau, colokan dan ember.

Excess success in “Don’t count calorie labeling out: Calorie counts on the left side of menu items lead to lower calorie food choices”
Authors: Francis Gregory , Thunell Evelina
Published: October 2019

Based on findings from six experiments, Dallas, Liu & Ubel (2019) concluded that placing calorie labels to the left of menu items influences consumers to choose lower calorie food options. Contrary to previously reported findings, they suggested that calorie labels do influence food choices, but only when placed to the left because they are in this case read first. If true, these findings have important implications for the design of menus and may help address the obesity pandemic. However, an analysis of the reported results indicates that they seem too good to be true. We show that if the effect sizes in Dallas et al. (2019) are representative of the populations, a replication of the six studies (with the same sample sizes) has a probability of only 0.014 of producing uniformly significant outcomes. Such a low success rate suggests that the original findings might be the result of questionable research practices or publication bias. We therefore caution readers and policy makers to be skeptical about the results and conclusions reported by Dallas et al. (2019).

Conceptualizing Protective Family Context and Its effect on Substance Use: Comparisons Across Diverse Ethnic-Racial Youth
Authors: Constante Kevin , Huntley Edward , Schillinger Emma , Wagner Christine , Keating Daniel
Published: October 2019

Background: Although family behaviors are known to be important for buffering youth against substance use, research in this area often evaluates a particular type of family interaction and how it shapes adolescents’ behaviors, when it is likely that youth experience the co-occurrence of multiple types of family behaviors that may be protective. Methods: The current study (N = 1716, 10th and 12th graders, 55% female) examined associations between protective family context, a latent variable comprised of five different measures of family behaviors, and past 12 months substance use: alcohol, cigarettes, marijuana, and e-cigarettes. Results: A multi-group measurement invariance assessment supported protective family context as a coherent latent construct with partial (metric) measurement invariance among Black, Latinx, and White youth. A multi-group path model indicated that protective family context was significantly associated with less substance use for all youth, but of varying magnitudes across ethnic-racial groups. Conclusion: These results emphasize the importance of evaluating psychometric properties of family-relevant latent variables on the basis of group membership in order to draw appropriate inferences on how such family variables relate to substance use among diverse samples.
Using metamemory measures and memory tests to estimate eyewitness free recall performance
Authors: Saraiva Renan Benigno , HOPE LORRAINE , Horselenberg Robert , Ost James , Sauer James D. , van Koppen Peter
Published: October 2019

Using a mock witness methodology, we investigated the predictive value of metamemory measures and objective memory tests as indicators of eyewitness free recall performance. Participants (n = 208) first completed a metamemory assessment that included assessments of self-rated memory capacity, memory development and use of strategies. In a separate session, participants watched a mock crime video and provided a free recall account, followed by one out of four independent memory tests (i.e., free recall, cued recall, face recognition and general knowledge). Accuracy, amount of details reported, confidence and over/underconfidence in the eyewitness free recall were the main dependent variables. Results indicated three main findings: (1) subjective assessments of memory capacity were not related to eyewitness free recall performance; (2) although individual confidence and over/underconfidence was somewhat stable across different memory tests, accuracy was less stable; and (3) individuals with higher self-rated memory capacity had a slightly stronger confidence-accuracy relation in free recall. These results are discussed with respect to metamemory assessments and performance stability across memory tests of different domains.
Volitional control of piloerection: objective evidence and its potential utility in neuroscience research
Authors: Katahira Kenji , Kawakami Ai , Tomita Akitoshi , Nagata Noriko
Published: October 2019

The ability of volitional control of piloerection has been reported in a rare subset of individuals. This ability may be useful to study involuntary emotional piloerection, as research on this phenomenon has suffered from low reproducibility. However, objective evidence at a group-level and stability under experimental constraints remain to be examined. The present study aimed to validate existing findings of voluntary generated piloerection (VGP) and to examine its potential contribution to neuroscientific research based on objective evidence of this ability. In Study 1, to confirm the characteristics of VGP reported in previous studies and identify individuals with VGP capability, an online survey of VGP candidates found through a large-scale screening was conducted. In Study 2, a total of 18 VGP holders participated in a mail-based piloerection measurement experiment, and the nature of VGP was examined based on the objective evidence obtained by image-based analysis (GooseLab). The results of the web survey largely recapitulated the characteristics of VGP reported in previous studies, and objective measurements revealed the utility of this ability in neuroscientific research. For some participants, VGP appeared to be emotionally promoted, which suggests that VGP shares the emotional nature of involuntary piloerection. The findings from this study demonstrated the possible contribution of VGP to elucidating the mechanism of involuntary emotional piloerection and the neural basis of piloerection itself.
The Development of Quantity Implicatures in Mandarin-Speaking Children
Authors: Zhao Shuyan , Ren Jie , Frank Michael C. , Zhou Peng
Published: October 2019

The present study reports a large, cross-sectional study of Mandarin-speaking children’s ability to compute pragmatic inference. To chart the developmental trajectory of this pragmatic ability, we tested 225 Mandarin-speaking children (aged 4-8 years) on three types of pragmatic implicatures: scalar, context-dependent, and numeral implicatures. The results show that scalar implicatures posed difficulties for young Mandarin-speaking children, and they did not exhibit a consistent success until age 6. In contrast, by four years of age, this group was already able to compute context-dependent and numeral implicatures in an adult-like fashion. The implications of the current findings are discussed concerning children’s development of pragmatic inference as well as the relevance of cross-linguistic data in understanding pragmatic development.
Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players

Published: October 2019

Sprint performance is an essential skill to target within soccer. However, time-consuming intervention models could be easily rejected by coaches. Therefore, alternative and efficient field training options are warranted. One such method could be heavy resisted sprint training. However, it is unknown whether such overload will be efficient in assisting increases in sprint performance in a professional setting, and whether violating kinematic specificity via heavy loading will lead to changes in unloaded sprinting kinematics. Thus, we investigated whether heavy resisted training affects sprint performance and sagittal plane kinematics. Training-induced changes in sprint FV-profiles were computed before and after the 9-week, 2 sessions x week protocol. Out of the two recruited teams (N = 32, age: 24.1 ± 5.0 years: height: 180 ± 10 cm; body-mass: 76.7 ± 7.7 kg), one was used as a control group continuing training as normal (CON, N = 13), while the experimental team was divided into two subgroups based on their initial sprint performance: 1) Heavy sled training with the 60% velocity drop (N = 10) and 2) 50% velocity drop load (N = 9). Both experimental groups improved significantly all 0-30-m split times (p < 0.05, d = -0.62 – -1.25), with post-hoc showing HS50% improving significantly compared to CON in 0-10-m split (d = 1.03) and Pmax (d = 1.16). No differences in sprinting kinematics were observed. With appropriate coaching, heavy sled training could be a pragmatic option to assist improvements in sprint performance without adverse changes in sprinting kinematics in professional soccer players.

Authors: Suastiyanti Dwita , Topan Bambang Agus , Wijaya Marlin
Published: October 2019

Aluminium paduan Al-Mg-Si khususnya T6061 merupakan paduan yang pada umumnya diaplikasikan untuk otomotif dan alat-alat konstruksi. Penelitian ini diarahkan untuk peningkatan sifat mekanis khususnya kekerasan material T6061 untuk diaplikasikan sebagai selongsong peluru. Selama ini material untuk selongsong peluru banyak menggunakan kuningan yang mempunyai density yang lebih besar daripada aluminium padahal sebagai selongsong peluru diperlukan material yang ringan tetapi kuat sehingga dapat menembakan peluru dengan lancar dan mudah. Untuk peningkatan sifat mekanis dilakukan perlakuan panas precipitation hardening melalui proses pemanasan pada temperatur 500oC selama 1 jam kemudian dicelup di dalam air sampai mencapai temperatur kamar, setelah itu untuk peningkatan kekerasan dilakukan proses aging (penuaan) pada temperatur 90, 120, 150, 180 dan 210oC masing-masing selama 8,9 dan 10 jam. Karakterisasi aluminium setelah mengalami precipitation hardening adalah dengan melakukan pengujian kekerasan metode Vickers dan pengamatan struktur mikro. Dari hasil pengujian kekerasan diperoleh hasil bahwa kekerasan terus meningkat mulai dari temperatur aging 90oC sampai dengan temperatur aging 150oC. Kekerasan maksimum diperoleh pada temperatur aging 150oC sebesar 103 HV. Di atas temperatur 150oC terjadi penurunan kekerasan yang menandakan bahwa terjadi over aging pada temperatur di atas 150oC yang ditandai dengan makin membesarnya presipitat Mg2Si. Kondisi aging optimum yang dapat diterapkan untuk precipitation hardening T6061 yang diaplikasikan untuk selongsong peluru adalah  temperatur aging 150oC selama 8, 9 dan 10 jam.

Sitting is one of the rest activities carried out by humans to restore energy when tired of doing activities and a bench is an infrastructure that humans use to sit when they unwind. The most important factor for bench design is a convenience for its users. While the table is an infrastructure that is used by humans to carry out writing, eating and so on. Combining bench and table concepts into one, it is very necessary to summarize the place according to its function. The literature study on this design gave rise to a new design in which a multifunctional bench is not only useful for sitting but also functions to carry out activities that require a desk.

Most institutional anthropology departments have a website, to tout credentials, attract students, and offer information. These websites also take up the visual task of disciplinary representation, but their images have skipped the scrutiny that is necessary and overdue. Th is article analyzes online images of sociocultural anthropology across one hundred high-ranking universities worldwide. We show how, online, a discipline defined by diversity becomes readily reducible to “exotic” geographies and objectified “others.” While the urban serves as an unattractive foil, frequent images of children recall charity campaigns. Such visual tropes—which comprise a significant, public interface for anthropology—are not just awkwardly dated but also do disservice to ambitions for public anthropology.

DETERMINATION OF REGULATORY RELIABILITY FOR DEFORMATION OF REINFORCED-CONCRETE FLEXIBLE STRUCTURES
Authors: Gerasimov E. P.
Published: October 2019

Strength, stiffness, crack resistance requirements must be specified for any structure. These requirements are provided by the appropriate calculations. Compliance with all requirements ensures the design reliability. But due to the fact that structural analysis is performed by the limit state method, the numerical value of the reliability cannot be determined. This can be done only by applying probabilistic methods of calculation. One of the major obstacles to the use of probabilistic methods is the lack of standardized values of the structural reliability (normative reliability).

Although probabilistic methods of calculation were developed in late in the 20th century, the assignment of normative reliability values encountered serious obstacles. The most serious obstacle was the consideration of the failure consequences as some consequences were quantifiable. On the other hand, much work concerned the assignment of normative structural reliability based on their bearing capacity. Only few works related to the reliability normalization using deformation and crack resistance.

This paper deals with the regulatory definition of reliability using the deformation of reinforced-concrete bendings based on physiological requirements. A method for determining the normative reliability based on human sensitivity to fluctuations is proposed. The normative reliability of precast slabs is determined using the proposed method.
COMPACTION OF SATURATED SOILS WITH REGARD TO COMPRESSIBLE PORE FLUID AND SOIL CREEP
Authors: Smolin Yu. P. , Vostrikov K. V.
Published: October 2019

The paper describes the problem of consolidation of clay soil with spherical tensor and stress deviator, taking into account compressibility of pore fluid and the soil creep. In solving the problem, the differential equation is suggested for compacting cohesive soil filled with linearly compressible groundwater. It is considered that the gas volume in the groundwater does not exceed 10 %. The solution of the differential equation is based on the Fourier transform.

For the numerical calculation of creep during compaction of consolidated soil an easy-touse method was used, i.e. testing of soil samples of the same monolith in the compression device, but different height. Knowing the relative vertical deformation of these samples, approximation and extrapolation methods allow to find the relative deformation at the sample height tending to zero. At almost zero sample thickness, deformation depends only on the soil creep, while the pore pressure will no longer play a role.

The obtained values of the relative strain are used to select the function of the creep nucleus. It is found that the exponential function optimally describes the process of soil compaction over the entire area: from the beginning of compaction to its termination.

Knowing the pressure, the stress in soil and the amount of sediment are found with a triaxial compression, taking into account its instantaneous deformation.

Geliat pariwisata yang kian eksis pada daerah wisata Senggigi Kabupaten Lombok Barat berdampak pada semakin terbukanya lapangan kerja, baik bagi masyarakat asli sasak tak terkecuali pula masyarakat Jawa Barat. Para pekerja yang datang dari Jawa Barat berkomunikasi dengan Bahasa Indonesia dan Bahasa Sunda. Mereka memilih untuk tinggal berkelompok sesama Orang Sunda, yang secara otomatis akan menggunakan Bahasa Sunda untuk bekomunikasi sehari-hari. Bahkan tempat tersebut telah dijuluki Kampung Sunda. Bahasa Sunda sudah mendominasi Bahasa Sasak di tempat itu, yang notabene Bahasa Sasak merupakan bahasa daerah orang Lombok. Orang-orang Lombok yang berada di lingkungan tersebut seakan-akan lebih bangga menggunakan Bahasa Sunda daripada Bahasa Sasak.Berdasarkan pemaparan di atas, tujuan penelitian ini adalah untuk memahami bentuk eksistensi Bahasa Sunda pada Lingkungan Etnis Sasak di Desa Senggigi Kecamatan Batu Layar Kabupaten Lombok Barat serta faktor yang menyebabkan Orang Lombok di lingkungan itu lebih suka menggunakan Bahasa Sunda daripada Bahasa Sasak. Untuk memahami hal tersebut diperlukan metode penelitian yakni metode wawancara dengan teknik catat rekam.Berdasaran hasil penelitian di lapangan didapatkan hasil bahwasanya Bahasa Sunda yang dikuasai oleh orang Sasak masih pada tataran sederhana seperti kata-kata sapaan biasa. Meskipun tidak menutup kemungkinan orang-orang Sasak yang senantiasa berinteraksi dengan orang Sunda akan menguasai Bahasa Sunda secara baik pada tataran sulit, namun sementara ini kata-kata yang kerap diucapkan berkisar pada kata-kata seperti, eta mah, ieu, hatur nuhun, sami-sami, kadie, didie, naon, kumaha, aing, abdi, aya-aya wae, bogoh, teteh, akang, aa, eceu,sabaraha, dan beberapa kata sederhana lainnya.
