Quantum size effect in Pb(100) films: the role of symmetry and implication for film growth

We show from density-functional calculations that Pb(100) thin films exhibit quantum size effect with a bilayer periodicity in film energies, film relaxations, and work functions, which originate from different symmetry of the stacking geometry of odd and even layer films. The bilayer periodicity of the film energy is argued to survive on a semiconductor substrate, which should allow the growth of ``magically'' thick even-layer Pb(100) films. Furthermore, it is found that the quantum well states in a simple metal film can be classified into $\sigma$-bonded and $\pi$-bonded states, which quantize independently

Investigating the Role of Tax Consultant in Urgencies of Voluntary Disclosure Program 2022

The government has made numerous attempts to raise tax revenues in response to the Covid 19 outbreak, either by enhancing or perfecting tax laws. The Voluntary Disclosure Program (PPS) is one of the government's policies. PPS is sometimes referred to  Tax Amnesty Volume II. This study intends to investigate the influence of PPS policy on perceptions of taxpayer compliance and the function of tax consultants as a moderating factor. Primary data were collected randomly through the distribution of online questionnaires and obtained 33 respondents as samples. The data analysis technique used is the Moderated Regression Analysis (MRA) interaction test. The test results prove that the PPS policy has a positive effect on the perception of taxpayer compliance and the role of the Tax Consultant is proven as a moderating variable that strengthens the relationship. The results of the study are expected to provide an empirical contribution to the taxation policies taken by the government so that they can be used as evaluation materials to innovate and educate the public in improving tax compliance and state revenues

The SLAC Polarized Electron Source

The SLAC PES, developed in the early 1990s for the SLC, has been in continuous use since 1992, during which time it has undergone numerous upgrades. The upgrades include improved cathodes with their matching laser systems, modified activation techniques and better diagnostics. The source itself and its performance with these upgrades will be described with special attention given to recent high-intensity long-pulse operation for the E-158 fixed-target parity-violating experiment.Comment: 6 pages, 4 figures, Workshop on Polarized Electron Sources and Polarimeters (PESP 2002), September 4-6, 2002, Danvers, M

Effect of Oral Iron Tablet Administration on Serum Feritin and Hemoglobin Concentration of Pre-pregnant Women with Mild Iron Deficiency Anemia in Bali

Iron deficiency anemia (IDA) is still to be a problem of pregnant women healthrelated to its high prevalence and its negative effects on health. Prevention efforts by ironsuplementation in pregnant woman have not reducing IDA problem in pregnant women yet. This failure is probably due to the assumption that IDA have been seen pre-pregnant. Totest this hypothesis, a quasi experimental study was conducted by randomized pre and posttest control group design. Sample were collected by multistage sampling random technicconsist of 47 women in treated group and 52 in control group. Both group were serumferritin and hemoglobin value test untill 3 time, pre-pregnant, early pregnant and duringpregnant. Iron tablet was administrated to treated group from the beginning of pre-pregnantperiod, continued until the first 3 months of pregnancy, while in control group iron tabletwas only given during the first 3 months of pregnancy. T-group result shown that meanserum ferritin and hemoglobin concentration at pregnant women on treated group(33,45±14,12 ?g/dL dan 12,25±1,20 g/dl) more high than control group (19,65±8,99 ?g/dLdan 10,91±0,67 g/dl), p<0,05. Mean difference serum ferritin and hemoglobinconcentration at pregnant women is 13,8 ?g/dL dan 1,34 g/dl (p<0,05). Benefid analysisresult shown that iron suplementation since pre-pregnant more benefid than ironsuplementation during pregnant (BCR >1). Based on these results, it can be concluded thatiron supplementation to IDA women starting from pre-pregnant period results in a bettereffect compare to oral iron supplementation during pregnancy only

Antioxidant Capacity Of Frangipani (Plumeria Alba) Powder Extract

This research aimed to identify the antioxidant capacity, vitamin C (ascorbic acid), and total phenolic compounds of frangipani flower powder. The powder was extracted using ethanol, methanol, acetic acid, and water (aquadest). Antioxidant capacity of each extract were determined using 2,2-diphenyl-1-picrylhydrazyl radical scavenging method, vitamin C were determined using 2,4 Dinitrophenylhydrazine, and total phenolic compounds were determined using Folin Ciocalteu reagent. All of parameters were measured by spectrofotometer. The result shows that the highest value of antioxidant capacity was ethanolic extract (18.19%) and the lowest value was acetic acid extract (12.74%). The highest value of vitamin C was aqueous extract (3.49 mg/100g) and the lowest value was acetic acid extract (3.02 mg/100g). The highest value of total phenolic content was aqueous extract (25.49 mg GAE/g) and the lowest value was acetic acid extract (22.74 mg GAE/g). In conclusion, the higher antioxidant capacity was not always followed by the higher of vitamin C and total phenolic compounds

Effects of Empowerment, Work Climate and Job Satisfaction on Employee Performance of Transportation Office of Klungkung Regency

To achieve maximum work results and satisfy, empowerment is needed by an employee in carrying out their duties so that employee performance can be improved. In addition, the work climate also affects employee performance. An open organizational climate encourages employees to express their interests and dissatisfaction without fear of retaliation and attention. In addition to the work climate, job satisfaction also affects employee performance, job satisfaction as a pleasant or positive emotional state that arises results from research on a job. The sample under this study was 63 employees at the Transportation Office of Klungkung Regency. The determination of the sample used the slovin method. The method in this recent study is quantitave approach and the analytical instrument used was multiple linear regression analysis; multiple correlation, determination, t test and F test. The results showed that the empowerment variable had a positive effect on employee performance as indicated by the significance value of 0.02

Universal entire functions with gap power series

AbstractLet M be the family of all compact sets in C which have connected complement. For K ϵ M we denote by A(K) the set of all functions which are continuous on K and holomorphic in its interior.Suppose that {zn} is any unbounded sequence of complex numbers and let Q be a given sub-sequence of N0.If Q has density Δ(Q) = 1 then there exists a universal entire function ϑ with lacunary power series 1.(1) ϑ(z) = ϵ∞v = 0 ϑvZv, ϑv = 0 for v ∉ Q, which has for all K ϵ M the following properties simultaneously2.(2) the sequence {ϑ(Z + Zn)} is dense in A(K)3.(3) the sequence {ϑ (ZZn)} is dense in A(K) if 0 ∉ K.Also a converse result is proved: If ϑ is an entire function of the form (1) which satisfies (3), then Q must have maximal density Δmax(Q) = 1
