Abstract (sommario):

This study investigates the influence of TRA86, pre-TRA86 tax strategies, and firm characteristics on S conversions in the natural resource industry. TRA86 shifted substantial individual tax costs to corporations, inviting conversions, but also lowered corporate marginal tax rates and changed aspects of the built-in gain provision to reduce conversion benefits. Built-in gain changes affect industries differently because of differences in asset composition and economic conditions. The natural resource industry had substantial built-in gain potential and was consolidating and restructuring during the mid-80s, making built-in gain realization likely. Our results suggest that built-in gains negatively influenced conversions in the natural resource industry. This study enhances our understanding of the interaction between TRA86 rate changes and other provisions on incentives to convert from C to S corporate status. It also contributes to the organizational form literature by identifying factors related to TRA86, S corporation operating restrictions, firm characteristics, and tax strategies that influence conversion decisions.

Abstract (sommario):

We investigate the cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) fiber ring loop theoretically and experimentally. Based on the XGM, a wavelength conversion is designed. We experimentally carry out an SOA wavelength conversion, which converts a 20 MHz sinusoidal modulated input optical signal at a wavelength of 1317 nm to an output optical signal at a wavelength of 1314.3 nm. In this type of wavelength conversion, a tunable optical filter is utilized to select the target wavelength of the output signal from the fiber ring loop, and this target wavelength signal is accumulated and amplified as the resonance of the fiber ring loop. The introduction of the tunable optical filter into the fiber ring loop system makes it very easy to obtain any desired target wavelength from this XGM wavelength conversion system; this remarkable property means that the SOA wavelength conversions have broader applications in optical networking and beyond. Higher frequency modulation XGM wavelength conversion may be obtained by scaling down the length of the fiber ring loop.

Abstract (sommario):

We study the blocking probability and performance of single-fiber and multifiber optical networks with wavelength division multiplexing (WDM). We extend the well-known analytical blocking probability model by Barry and Humblet to the general model, which is proposed for both single-fiber and multifiber network paths with any kind of wavelength conversion (no, limited, or full wavelength conversion) and for uniform and nonuniform link loads. We investigate the effect of the link load, wavelength conversion degree, and the number of wavelengths, fibers, and hops on blocking probability. We also extend the definition of the gain of wavelength conversion by Barry and Humblet to the gain of performance, which is fully general. Thanks to this definition and implementation of our model, we compare different WDM node architectures and present interesting results.

Abstract (sommario):

Background: Wireless power transfer is important for energizing and recharging the Internet-of-Things (IoT) cordlessly. Harnessing energy effectively from radio waves has become a crucial task. It is known that diversities at the transmitting antenna and waves (i.e. simultaneous continuous waves with center frequencies separated apart) can enhance the radio frequency (RF) to direct current (DC) energy conversion. What remains unknown is the extent of which the wave diversity enhances the conversion gain. This study attempts to examine the RF-to-DC conversion gain of applying wave diversity. This paper investigates the effects of wave diversity on the energy conversion efficiency, and contributes the analytical expression that relate the conversion efficiency to the diversity count, i.e. the number of simultaneously transmitted sinewaves. Methods: We adopted a theoretical approach to the problem. First, we derived and presented a theoretical model that incorporated different forms of transmit diversity, i.e. antenna and wave diversities. This model then connected a RF-to-DC energy conversion model resulting from polynomial fitting on circuit simulation results. With the availability of these two models, we determined the theoretical energy conversion gain of simultaneously transmitting multiple sinewaves. Results: The results showed that transmitting multiple sinewaves simultaneously yields diversity gain and higher energy conversion efficiency. Most importantly, the gain and conversion efficiency can now be theoretically quantified. For example, at certain RF power measured at the receiver circuit, the diversity gain of transmitting four sinewaves is 2.6 (as compared to transmitting single sinewave). In fact, both the diversity gain and conversion efficiency increased with the number of simultaneously transmitted sinewaves. In another example, the conversion efficiency of transmitting four sinewaves is 0.1 as compared to 0.075 of two sinewaves. Conclusions: In summary, this paper presents a novel analytical expression for wave diversity in the context of wireless power transfer.

Abstract (sommario):

The signal-variance method and the photon transfer curve method are the most valuable tools for calculating the conversion gains of charge-coupled device (CCD) detectors. This paper describes the phenomena that arise in the conversion gain measurements of space multi-band variable object monitor (SVOM) visible telescope (VT) CCDs, where the results of the signal-variance method increase with the image gray level, and the results of the photon transfer curve method appear with nonlinearity, which is caused by the signal-dependent charge sharing mechanism of back-illuminated CCDs. A numerical simulation model based on random variables was adopted to analyze the influence of the mechanism on the gain determination. The model simulates all the signals and noise in the flat field image, including the photon signal and photon-shot noise, readout noise, fixed pattern noise, and the signal-dependent charge-sharing signal, and it demonstrated agreement with the experimental data. Then, we proposed a quadratic polynomial curve-fitting formula for the photon transfer curve, and we quantitatively analyzed the relationship between the fitting coefficients and the gain, the signal-dependent charge sharing coefficient, and the full well capacity using the control variable method. Finally, the formula was used to accurately determine the conversion gains of SVOM VT CCDs.

Abstract (sommario):

This paper reports a reconfigurable wideband passive mixer for direct conversion multimode multi-standard receivers. Different from the traditional current-commutating passive mixers, transconductor stage of this design is variable. And the TIA stage is a second-order low-pass transimpedance amplifiers based on Tow-Thomas biquad topology, working as a current mode filter. The mixer is controlled by a 4-bit control word to realize the flexible gain and variable intermediate frequency bandwidth. Other characteristics such as power consumption, NF, and linearity is also reconfigurable according to different communication standard. Circuit is implementing in 0.18μm CMOS technology. Post-simulation results show that, with the radio frequency ranges from 700 MHz to 2.6 GHz, it provides four voltage conversion gains (10/16/22/28dB) and three-3 dB intermediate frequency bandwidth (5/7.5/10MHz). Under the maximum gain, the double sideband NF of the mixer is 8.4 dB. And under the minimum gain, IIP3 is 13 dBm. The chip occupies an area of 0.248 mm2 and drains a current of 8.5mA from a 1.8 V supply when the mixer has highest gain.

This article discusses the advantages and disadvantages of translation and conversion of currency. Foreign currency translation is the process of reporting financial information from one currency to another. Foreign currency transactions take place on the spot, forward, or swap markets. Currencies bought or sold on the spot generally have to be delivered as soon as possible, that is, within 2 working days. Foreign currency translation is carried out to prepare joint financial reports. Translation is simply a change in monetary units, just as a balance sheet expressed in British pounds is restated into its US dollar equivalent. No physical exchange takes place, and no related transaction occurs as if a conversion were made.

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits.

Abstract (sommario):

Switch mode dc-dc converters are attractive for their small size, ease of control and efficient power conversion. Output voltage is regulated by duty cycle control of semiconductor switch of switch mode dc-dc converters. The voltage gain and efficiency of practical switching regulators deviate from ideal values at extreme duty cycles. Also, desired gain /attenuation is not achievable at high/low duty cycles. In applications where high gain or high attenuation of voltage is desired with acceptable energy conversion efficiency, hybrid dc-dc switching converters are used. Hybrid dc-dc converters are combination of voltage multiplier/division circuit with appropriate SMPS circuits. By incorporating voltage multiplier/division cell with conventional SEPIC converters, desired voltage gain (either very low or very high) may be achieved at acceptable energy conversion efficiency. In the present work with an aim to attain very high voltage gain by conventional SEPIC topologies, a new voltage multiplier cell consisting of multiple inductors and diodes is proposed.

One hundred and twenty snails were subjected to four dietary treatments of T1, T2, T3 and T4 with 0%, 0.25%, 0.5% and 0.75% sodium chloride respectively. The treatments were replicated thrice with 10 snails per replicate. The measured parameters included weight gain, feed intake, shell length, shell circumference and shell thickness. Feed cost, cost of feed per kg weight gain and feed conversion ratio were also calculated. Results showed that there were significant differences (p < 0.05) in average daily weight gain, average daily feed intake, feed conversion ratio, feed cost and shell thickness but there were no significant differences (p > 0.05) in cost of feed per kg weight gain, shell length and shell circumference in the snails fed the treatment diets. Treatment 2 had the highest average daily weight gain (0.07±0.01), average daily feed intake (0.91±0.08) and feed cost (7.19±0.64) but the lowest feed conversion ratio (13.15±61.76) while treatment 1 had the lowest average daily weight gain (0.04±0.01), average daily feed intake (0.70±0.20) and feed cost (5.54±0.18) but the highest feed conversion ratio (15.86±0.5). This shows that inclusion of sodium chloride above 0.25% in the diet of Archachatina marginata affects both the feed intake and weight gain of the snails.

Abstract (sommario):

The objective of this study was to evaluate the performance of sheep fed with diets consisting of different proportions of soybean silage and sugarcane tip silage. Twenty four lambs from Morada Nova breed were used, with an average age of 75 days and average weight of 16.98±2.62kg. The following diets were evaluated: T1 = 20% sugarcane tops silage + 80% concentrate, T2 = 20% sugarcane tops silage + 30% soybean silage + 50% concentrate, T3 = 20% sugarcane tops silage + 60% soybean silage + 20% concentrate. The experimental design was a randomized complete block with eight repetitions and each animal was a repetition. It was evaluated the intake of dry matter, organic matter, ash, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, weight gain, and feed conversion ratio and efficiency. The total weight gain, average daily gain, feed conversion ratio and efficiency were similar, with average values of 7.9kg animal-1, 133.3g animal-1 day-1, 6.2 and 0.17, respectively. Diets based on sugarcane tops silage enriched with soybean silage + concentrate provide greater nutrient intake in relation to diet composed only of sugarcane tops silage + concentrate. Sugarcane tops silage supplemented with protein concentrate or enriched with soybean silage with lower inclusion of concentrate resulted in similar weight gains and feed conversion efficiency.

Abstract (sommario):

A 70-day feeding trial was conducted to estimate the effect of levels (0, 5, 10, and 15g/kg cassava peels, respectively) of common salt and cassava peels (dry and fresh using Gmelina arborea leaves as a basal diet on the average daily gain, dry matter intake, seed conversion efficiency and water consumption in West African Dwarf goats. Total dry matter intake and the average Gmelina arborea leaf intake increased with applied common salt, irrespective of cassava peel form. Increasing common salt level also increased average daily gain and feed conversion efficiency in both dry and fresh cassava peels, but this was not accompanied by a remarkable gain beyond 5g common salt. Moreover, the average cassava peel intake increased but not significantly (P>0.05) with salt level up to 10g beyond which there was a sharp decline and an insignificant gain with dry and fresh cassava peels, respectively. Goats fed dry cassava peels significantly (P<0.05) consumed more water as the salt level increased in the diet. It was concluded that application of 5g common salt per kg dry cassava peels promoted highest daily gain, optimum dry matter intake and feed conversion efficiency in West African Dwarf goal production. However, the response with fresh cassava peels revealed no statistically significant difference in average daily gain, total dry matter intake and feed conversion efficiency.

Abstract (sommario):

Two 81-96 GHz frequency triplers, one balanced and one single device, are implemented using a 0.10 μm GaAs pHEMT process. The EM simulation results show that the triplers perform a best conversion gain of -6.8 and -4.7 dB for the balanced and the single device, respectively. The conversion gain of the balanced tripler operating from 81 to 96 GHz is above -9.6 dB at 3dBm input power. The conversion gain of the single device operating from 81 to 96 GHz is above -8 dB at -0.5dBm input power. The fundamental and second harmonic suppression are as high as 30 dB over the whole operating frequency (81-96 GHz) for both circuits.

Abstract The aim of the research was to study the effects of synchronization index in the sugarcane bagasse based complete feed on feed intake, daily body weight gain and feed conversion ratio of sheep. Two permanent cannulated male local sheep was 2 years old to create formulation of three diets with different synchronization index, namely 0.37; 0.50 and 0.63 respectively. Fifteen local male sheep with body weight average of 18,32 kg (cv= 14,39%) and aged at 12 months were feed a complete feed based on bagasse with a level of synchrony index 0,37; 0,50; 0,63 were design isoprotein and isoenergy. The treatments were allotted in a randomized block design with 3 treatments and 5 groups for in-vivo test. The feed intake, daily body weight gain and feed conversion ratio of fifteen rams were determined on week 8 of experimental period. The results of the study indicated that the synchrony index did not effect on feed intake, but daily body weight and feed conversion ratio was affected (P<0.05) by the treatment of synchrony index in diet. The daily body weight gain of P2 group was highest compared with P1 and P3 groups. The feed conversion ratio of P2 group was lowest compared with P1 and P3 groups. The alteration of the study indicated that the synchronization index level of 0.50 showed the best weight gain and feed conversion. Keywords: daily body weight, feed conversion ratio, feed intake, synchrony index

Abstract (sommario):

The purpose of this study was to determine consumtion, weight gain, and conversion of super-native chicken rations feed with fermented sago pulp. Sago pulp is a potential local resource for alternative poultry feed as well as an energy source, this can be seen from the metabolic content of sago pulp reaching 2340 kcal / kg, crude protein 3.40%, and crude fiber 11.61%. The purpose of this study was to determine consumption, weight gain, and conversion of super native chicken rations fed with fermented sago pulp. The research method is an experiment using a completely randomized design. The treatment ration used was T0 = (0% ASF), T1 = (10% ASF), T2 = (20% ASF) T3 = (30% ASF), Each treatment was repeated five times. Variables observed were ration consumption, weight gain, and ration conversion. The results of the study there were consumption, weight gain T3 (30% ASF), T2 (20% ASF), and T1 (10% ASF) significantly higher than treatment T0 (0% ASF). The lowest avarage ration conversion results are found in treatment T1 which is 2,40. The conclusion that fermented sago pulp (ASF) can be used in super native chicken rations to the level of 30%.
