Abstract

Unique character and common behavior are two distinguished things. In frontier nanoscience and nanotechnology, unique characters were normally obtained in some novel exotics materials such as metal-metal core-shell materials, metallic-semiconducting hybrid nanomaterials, and organic-inorganics complex nano-compounds. On the other hand, normal behavior of natural phenomena including in nano-size objects were obviously predicted based on their exact size related to confinement effect, and capability to interact with another physical system in nature. Here, we report an example of unique character due to evolution nonlinear behavior observed in gold nanorod with their aspect-ratio dependence of optical nonlinearities investigated by femtosecond Z-scan measurements closed to resonance longitudinal surface plasmon peak in gold nanorods (Au NRs). Saturable absorption manifests itself at low excitation (laser irradiances < ~7.0 GW/cm2), while reverse saturable absorption dominates at higher excitation. Both the nonlinear processes are found to increase with the aspect ratio of Au NRs. Based on the discrete dipole approximation, qualitative explanations are presented for the observed nonlinear behavior. While common behavior in metallic quantum dots or other shapes of metallic nanomaterials was not the significant in our observation.

Abstract

The influence of calcination temperatures in TiO2 impregnated Ouw’s natural clay on its degradation activity of methylene blue dye has been done. Calcination process was conducted at various temperatures of 200, 300, and 400 oC. The characterization of TiO2 impregnated clay’s structure was examined by IR analysis. The result showed that Ouw’s natural clay has characterized vibrations of montmorillonite and thermal effect didn’t affect the structure of TiO2 impregnated clay. The highest result of methylene blue’s degradation occurred in the addition of TiO2 impregnated clay calcinated at 200 oC (98.69%). This result was found that calcination temperatures of impregnation process were significantly affect the degradation activity of TiO2­ impregnated clays.

Abstract

To know sensory characteristic of jelly candy based on consumers acceptances. This research used trial method, with ratio between Caulerpa sp and sugar were 1:0.5, 1:1 and 1:1.5. Result of consumer acceptances tests toward color, taste, texture and odor of Caulerpa jelly candy was collected using hedonic range. Caulerpa seaweed could be processed to be jelly candy with consumer acceptance level in range “neutral” to “like”. The highest level of consumer acceptance was on the Caulerpa ratio 1:1.5 with acceptance level for color, odor and texture were “not much like”, meanwhile acceptance level for taste was “like”.

Abstract

A widely used estimation method in estimating regression model parameters is the ordinary least square (OLS) that minimizes the sum of the error squares. In addition to the ease of computing, OLS is a good unbiased estimator as long as the error component assumption () in the given model is met. However, in the application, it is often encountered violations of assumptions. One of the violation types is the violation of distributed error assumption which is caused by the existence of the outlier on observation data. Thus, a solid method is required to overcome the existence of outlier, that is Robust Regression. One of the Robust Regression methods commonly used is robust MM method. Robust MM method is a combination of breakdown point and high efficiency. Results obtained based on simulated data generated using SAS software 9.2, shows that the use of objective weighting function tukey bisquare is able to overcome the existence of extreme outlier. Furthermore, it is determined that the value of tuning constant c with Robust MM method is 4.685 and it is obtained95% of efficiency. Thus, the obtained breakdown point is 50%.

Abstract

Recently producing profit by exchanging currency of one country with that of the other has been conducted among traders. This activity is called “FX” – the abbreviation of Foreign eXchange. The fluctuation of the price of currency is caused by the psychology of traders so that it apparently varies at random. However, after so many traders take part in FX, the trend of currency expectedly shows several patterns and is said to be subject to a certain principle which was firstly suggested by R.N.Elliott (1871-1948). In our recent research, we have tried to construct an algorithm relying on this Elliott wave principle and establish an automated transaction of FX by a computer. One of the aims of this PC-algorithm is to determine the line graph which well-approximates a real currency fluctuation under the constraints of the Elliott principle. In this paper, we will survey how to construct an algorithm for well-approximating line graph, and theoretically discuss the least number of intersection points in currency fluctuation and the well-approximating line graph, which enhances the validity of the algorithm.

Abstract

Here, one reported a discovery of new golobe or a novel kind of zingiberaceae fruit in a forest of Layeni village located in Teon-Nila-Serua (TNS) district of Seram island, Maluku province, Indonesia in the late afternoon on 25th February 2019. The new golobe is very different from the four (4) formal types of golobe fruits studied before. After intense prompt investigations, the new golobe was named as Elim alliacea based on the taller tree and fruit hard skin structures as well as its unique taste. Furthermore, the healing system of the golobe was identified to be very excellence in handling toxic instantly. This discovery suggests a prominent potential of this fruit as multitasking healing herbal medicine for future complicated deceases on earth.

Abstract

The study was conducted in Wai Sari sub-watershed, Western Seram Regency Maluku to develop an accurate land degradation assessment model for tropical small islands. The Stocking’s field land degradation measurement and RUSLE methods were applied to estimate soil loss by erosion and the results of both methods were statistically tested in order to obtain a correction factor. Field indicators and prediction data were measured on 95 slope units derived from the topographic map. The rates of soil loss were calculated according to both methods, and the results were used to classify the degree of land degradation. The results show that the degree of land degradation based on the field assessment ranges from none-slight (4.04 - 17.565 t/ha/yr) to very high (235.44 - 404.00 t/ha/yr), while the RUSLE method ranges from none-slight (0.04-4.59 t/ha/yr) to very high 203.90 - 518.13 t/ha/yr. However, the RUSLE method shows much higher in average soil loss (133.4 t/ha/yr) than the field assessment (33.9 t/ha/yr). The best regression equation of logD/RP = - 0.594 + 1.0 logK + 1.0 logLS + 1.0 logC or D = 0.2547xRxKxLSx CxP was found to be a more suitable land degradation assessment model for a small-scale catchment area in the tropical small islands.

Abstract

In providing the best nanocarbon-based medicine particularly associated with their multitasking healing system, an advanced knowledge and understanding of physical chemistry engineering is compulsory. Discovery of the first spherical nanocarbon cage C60, namely, fullerene or buckyball by R. Smalley and his colleague in ~1986 at Rice university made the former elected as a chemistry Nobel laureate 10 years later in 1996. Various investigations in conjunction with fullerenes had been tremendously pursued in many interesting research fields, especially, on its characters including nonlinear and optical limiting behaviors, ultrafast dynamics of electrons in 5-level models, and advanced theoretical and computational cooperation system involving fullerenes encapsulated in a carbon nanotube (CNT). This present editorial communication stimulates an alternative view of physical chemistry engineering of fullerene and its derivatives functioning as nanofullerene-based medicine and its potential healing impacts. Our aims focus on the use of such non-toxic nanocarbons for various broad application leading to a number of different medicinal products.
