The use of oxygen modified graphite-like carbon nitride (C3N4Ox), photosensitive in the visible region of the optical spectrum, along with TiO2, photocatalytically active only in the ultraviolet region of the spectrum, in the C3N4Ox/TiO2 binary photocatalyst, opens a possibility of the use of sunlight energy. To increase opportunities of various kinds of photochemistry-related applications of C3N4Ox/TiO2 photocatalyst, the phase composition of the TiO2 matrix and morphology of nanoparticles of composite and their optical properties are very important. A novel composite material, C3N4Ox/TiO2, was synthesized in the present work in accordance with the approach developed in Frantsevich Institute for Problems of Materials Science of NASU for the synthesis of powdered oxygen-doped carbon nitride (C3N4Ox) by CVD method under the special reactionary conditions of the melamine pyrolysis, in particular, in the presence of a fixed air volume. Deposition of C3N4Ox carried out on the surface of a nanostructured powdered TiO2 matrix of different phase composition, rutile or anatase. The deposition of C3N4Ox (~5 % O) on both rutile and anatase nanopowders was confirmed by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis-DRS) methods. SEM micrographs (recorded with a MIRA3 TESCAN scanning electron microscope) of nanoparticles of both C3N4Ox/TiO2 composites (anatase and rutile phases) demonstrate the arrangement of TiO2 as separate globular nanoparticles and clusters between the plates and in the channels of the porous scaly plates C3N4Ox. However, the anatase phase nanoparticles (synthesized in IPM NASU) have a higher dispersion, the average size of non-aggregated almost monodisperse particles is about 10 nm. Using UV/Vis spectroscopy, it has been found that a redshift of long-wavelength edge of the fundamental absorption band of the spectra is observed when going from TiO2 (anatase), TiO2 (rutile), C3N4, C3N4Ox/TiO2 (anatase), C3N4Ox/TiO2 (rutile) and, then, to C3N4Ox, and the band gap decreases from 3.2, 3.0, 2.6, 2.4, 2.25 to 2.1 eV in the above sequence of materials. In such a case, C3N4Ox/TiO2 (especially deposited on anatase phase) would absorb more visible light than g-C3N4 and TiO2, by generating more charges which favor the improvement in the photoactivity of the catalysts.


This paper presents operational performance results of grid‐connected PV systems in Germany, as collected and elaborated for the Photovoltaic Power Systems Programme (PVPS) of the International Energy Agency (IEA). Performance ratios obtained from 235 PV installations in Germany and from 133 PV plants in other countries are compared and discussed. For Germany, a significant rise in PV system performance and reliability was observed for new PV installations due to higher component efficiencies (e.g., inverter) and increased availabilities.


Most reports available in literature on the liquefaction of cellulosic materials, usually stop at giving approximate representative stoichiometric equations. Whilst these indicate rough approximation to what happens in the process of liquefaction, and whilst these have been extensively for works in this field it is my opinion that a better understanding of this process will lead to more realistic and profitable designs for future commercial plants.


Female southern elephant seals, Mirounga leonina, assemble in large groups and each gives birth to a single pup which is nursed for some 3 weeks. Weaning mass is highly variable; some pups are three times as heavy as others at weaning. After weaning, the pup fasts for several weeks before departing to sea. The function of this fast is unknown. We examined the relationships between maternal mass, pup weaning mass, and pup behaviour during the postweaning fast in 377 pups and 128 adult females over four breeding seasons at South Georgia. Pup weaning mass was positively related to maternal postpartum mass, which accounted for 55% of the variation in weaning mass. Over all 4 years male pups were significantly heavier at weaning than female pups (130 vs. 123 kg) but this difference disappeared after maternal mass was controlled for. After fasting for 21–66 days, weaned pups went to sea at an average of 68% of weaning mass. Heavier pups remained on the beach longer after weaning than lighter pups. There was no ...


Fresh findings from studies on childhood myopia have once again highlighted a much higher incidence of the eye condition globally.


Slab-waveguide molecular CO2 lasers with transverse RF discharge excitation are attracting attention through their compatibility with diffusion cooling and capability for high average power under scaled off conditions [1]. The slab waveguide resonator modes can be adequately described by simple rectangular EHml modes when the lateral Fresnel number of the cavity considerably exceeds unity. Very poor beam quality of the laser output (parameter M2 > 20) is the multimode mixture of a few different lateral modes with lateral index m of the resonator inserted between 1 and 50 [2]. Effective single-mode operation of a such laser can be obtained by so called Talbot selection of a lateral waveguide mode of the laser resonator [3]. It was accomplished via the insertion of a grid mode selector into the laser cavity to promote oscillation in a single high order waveguide mode. The spacing d of the grid wires is chosen to fulfil the Talbot imaging condition within the given rectangular waveguide structure according to Talbot condition L = (nd2/2λ), where L. is the cavity length, d is the wire spacing, λ is the wavelength, n is a small integer that represents the number of imaging planes on each round trip through the laser cavity. It was shown that the Talbot selection reduces output power to about 60-70% relative to multimode operation.


We have built and demonstrated a silicon-on-silicon multichip module for use in a cellular telephone. This module performs speaker-dependent voice recognition and also serves as a telephone answering device. It takes advantage of the miniaturization possible with MCM technology. Other important factors in the use of this approach are the fast design and fabrication cycle and the ability to readily integrate specialized CMOS processes into a single package.


Changes in traffic management measures were introduced in three areas in Helsinki and two areas in Stockholm; they resulted in a marked decrease in traffic volume in major streets. It was found that by reducing the number of intersections, the level of service of the street was raised. A survey was conducted of the attitudes of the public towards the modifications introduced. Only one factor, vehicle ownership, influenced the opinions of the respondents. It was also found that traffic restrictions are more easily accepted on through roads. /TRRL/


In the pre-Hann era, the graphs ? and ? were used interchangeably to represent two homophonous words, 'full moon' and 'look into the distance', both read wanq < *mjang(s). While the phonetic component of ? is obviously ?, it is not easy to identify a phonetic component in the form ?, and more difficult still for the earlier shell and bone inscription (SBI) form ?. In this paper I discuss the distribution of the three forms in inscribed and manuscript texts and in the transmitted pre-Hann corpus, the words represented by these graphs together with their associated word families, and the function of the graphic constituents of the three forms of the graphs.


Introduction The world bamboo forest area covers about 20 millions ha (Zhou et al. 1994) with 90 genera and 1200 species (Londoño 1990). Only in America, there are 440 native species, of which 320 are woody (Hidalgo 2003). In Colombia there are 95 known bamboo species comprising 19 genera, 9 woody and 10 herbaceaous (Londoño 1990). The Guadua genus is economically the most important and the species guadua (Guadua angustifolia Kunth) has been essential for rural communities (Londoño 2004). This bamboo species represents an important natural resource, traditionally being used by farmers to build long-lived products such as houses, furniture, handicrafts, agglomerates, veneers and flooring (Londoño 1998). During a recent inventory study an estimated area of 28,000 ha covered by guadua has been identified in the coffee region alone (Kleinn & Morales 2006).

This study is necessitated by the increasing rate of involvement of undergraduates in crime despite measures by tertiary institutions and government to curb the menace. It is principally aimed at identifying the reasons why undergraduates get involved in crimes, and how services marketing tools can be used to curb the crime menace. Secondary and primary data were utilized, with the latter obtained by administering copies of questionnaire and interview on undergraduates, graduate students and the Chief Security Officers of the selected Universities. Data analysis was done using descriptive statistics, while all the hypotheses postulated were tested using the multiple linear regression (MLR) model. The major findings include: the main reasons why undergraduates in Nigeria commit crime are; pear influence, poverty, lack of knowledge of the consequences of crime, high cost of acquiring higher education services, lack of security within the campuses, fear of unemployment after graduation, and weak parental upbringing; quality of education services offered by the universities contributes to prevention and control of crime among undergraduates; messages posted through social media networks can be used to prevent and control crime among undergraduates; attitude of staff of the universities contributes to prevention and control of crime among undergraduates; advertising messages against crime can prevent and control crime among undergraduates if done through newspapers, magazines, and radio; public relations and publicity activities by the institutions contribute to prevention and control of crime among undergraduates. Based on these findings, the study recommends among others that for tertiary institutions to prevent and control crime among undergraduates, they should: render quality services at reduced cost; post the consequences of crime to the social media; encourage staff to act as change agent to undergraduates; promote the consequences of crime through the appropriate advertising media; and implement the recommended public relations and publicity activities. These recommendations are represented in a model as: UCB = F (QES, ASP, SMN, ADM, PRA, and PBA).


Rapid growth of population, industrialization, and rise in living standards of communities has resulted in increasing environmental pollution and loss of natural resources, but also in the inaccessibility to quality energy services, especially the most and highly desired electricity particularly for majority of the population living in remote areas. So, in a bid to respond and tackle both at the same time, the challenges of lack of access to quality energy services and improper management and disposal of Municipal Solid Waste (MSW); a renewed awareness of renewable energies and best practice of Municipal Solid Waste (MSW) has to be created. In fact, the utilization of LFG for energy production, especially based on stand-Alone mini-grids or off-grids configurations is part of the growing complexity which contributes and plays a major role in promoting renewable energy for poverty alleviation, allowing economic growth in an environmentally friendly and responsible way. Following and going alongside the first paper previously developed which dealt with the technical, economic, and environmental assessment of deploying a Landfill Gas to Energy (LFGTE) generation system; the work in this paper develops and presents a comparative study of two different stand-alone schemes based on landfill gas to energy projects which are basically a Simple Stand-Alone system and Combined Heat and Power Stand-Alone system. However, the comparative study referred to in this research work is done by means of an economic assessment using the Hybrid Optimization Model for Electric Renewables (HOMER) software in order to develop the cost optimization analysis. In fact, the cost optimization analysis performed in this paper is based at first on the Net Present Cost (NPC) since this cost represents the total cost of the project including all cost components such as operational and maintenance (O&M), replacement, total capital cost, etc. and finally on the Cost of Energy (COE). The cost for the two configuration systems earlier mentioned are optimized, compared, and analyzed.

ABSTRACT Adolescents and young adults (AYA) carry a significantly higher risk for HIV infection compared to the general population. HIV-infected AYA also have poorer adherence and viral load (VL) suppression compared to older adult patients. Social support may provide an avenue for interventions to improve adherence and VL suppression in this population. We conducted a cross-sectional study in rural southwestern Uganda to examine the association between social support and VL suppression. We measured family cohesion and various sources of social support namely parent/guardian, teachers, classmates and friend using validated scales, and reliability of the scales using Cronbach's alpha was at least 0.70 on all of them. We defined VL suppression as having less than 1000 copies per ml. We used logistic regression analysis to calculate odds ratios (OR) for the association and to adjust for potential confounders. We enrolled 255 AYA, age range 12–24 years and 50.6% of them were male. Viral load suppression was present in 72.9% of them. In the multiple regression analysis, friend social support was associated with a 10% increase in the odds of VL suppression for every unit increase on the social support scale (OR = 1.10 95% CI 1.05, 1.14). Waiting for more than 15 minutes to see the doctor at the clinic was associated with an almost 2.5-fold increase in the odds of VL suppression (OR = 2.46, 95% CI (1.23–4.92). Males had 48% lower odds of having VL suppression (OR = 0.52, 95% Cl, 0.27–0.98) compared to females. Experiencing side effects on antiretroviral therapy (OR = 0.46 95% CI 0.22–0.95), and taking two or more pills per dose (OR = 0.21 95% CI 0.06–0.75) were associated with lower odds of VL suppression. In conclusion, social support is positively associated with VL suppression, and interventions to enhance social support should be developed and tested among HIV-infected AYA.


This paper describes a study on modelling the Received Signal Strength Indicator (RSSI) measured by the smartphone of a vehicle user. The present transmissions are emitted by dedicated radio frequency sources, such as Bluetooth Low Energy (BLE) beacons, mounted to the vehicle to determine the driver/passenger(s) proximity or relative position(s). Based on empirical data, a model of the measurements noise, which utilises skewed distributions, is proposed to capture inconsistencies in reception and the impact of occlusions on the RSSI profile in an automotive setting, for example occlusions in car parks. Experimental data is used to demonstrate the suitability of the introduced model.


In this paper we have studied the properties of strong-coupling magnetopolaron in quantum well by using linear-combination operator and unitary transformation method.The relations of the ground state energy of the magnetopolaron with the coupling constant,the well width and magnetic field strength are derived.Numerical calculations illustrate that the vibration frequency λ of the magnetopalaron increases with increase of the magnetic filed strength.The ground energy of the strong-coupling magnetopolaron increases with increase of the cyclotron frequency while the ground state energy of the magnetopolaron becomes smaller when the well width is larger,and the peculiar quantum size effect appears more obvious when the well width is smaller.


We investigate the transfer and capture dynamics of electrons in phase coherent photorefractive ZnSe quantum wells grown on GaAs using degenerate three-beam four-wave-mixing. The measurements reveal electron capture times by the quantum well in the order of several tens of picoseconds and a transit time of approximately 5 picoseconds from the GaAs substrate through the ZnMgSe barrier.

Adult education has a long history of interest in the development and transformation of the self. As such it is useful to consider a range of adult education programs as belonging to and extending the lineage of 'technologies of the self' identified by Foucault (1988). In all such programmes, even the most individualistic, there are implicit or explicit theorizations concerning the nature of the self and the way the self relates to others or to society more generally. The purpose of this paper is to explore the postmodern critique of the dominant theorizations of the self in adult education: the psychological/humanistic and the sociological/critical; and to comment on the 'solution' proferred by a postmodern theorization. The postmodern critique is valuable in drawing attention to the difficulties of theorizing some kind of originary, core, true, stable, or ahistorical self. Nevertheless it is important to acknowledge that in many of the sites in which adult educators work, the pursuit of a coherent, cont...


Twenty-eight new Heusler phases of title are prepared from the elements by induction heating (Nb ampoules, complex heating and annealing schedules).


We consider the flow of two-phases in a porous medium and propose a modified version of the fractional flow model for incompressible, two-phase flow based on a Helmholtz regularization of the Darcy phase velocities. We show the existence of global-in-time entropy solutions for this model with suitable assumptions on the boundary conditions. Numerical experiments demonstrating the approximation of the classical two-phase flow equations with the new model are presented.


The final products of the reactions of either [Mo(CO)6] or [Mo(CO)4(NBD)] (NBD = norbornadiene) with PPy3 (Py = 2-pyridyl) or ZPPy3 (Z = O, S, ClAu, C6F5Au) are fac-[Mo(CO)3(Py3P-N3)] or fac-[Mo(CO)3(Py3PZ-N3)], where the ligands act as tridentate N-donors. The use of ZPPhPy2 (Z = O, S) leads to fac-[Mo(CO)3(ZPPhPy2-Z,N2)], the ligands acting as tridentate Z,N2-donors. The crystal structure of fac-[Mo(CO)3(SPPhPy2-S,N2)] was determined by area detector diffractometry and shows that the coordination at molybdenum is essentially octahedral but with trigonal elongation. Some tetracarbonyl complexes which are intermediates in the formation of the above tricarbonyl complexes have been isolated (cis-[Mo(CO)4(PPy3-P)2] and cis-[Mo(CO)4(ZPPhPy2-Z,N)] (Z = O, S)) or detected (cis-[Mo(CO)4(Py3P-N2)] and cis-[Mo(CO)4(SPPy3-S,N)]). The syntheses of the new complexes [Au(C6F5)(PRPy2-P)] (R = Py or Ph) are also described.


Abstract This research study is a continuation to Sapam et al. [2019. Latin square designs with neighbour effects. Journal of the Indian Society of Agricultural Statistics 73 (2):91–98 (online).] wherein we studied the consequences of the presence of RN and CN Effects in an LSD of order 4. Here we continue our study for LSDs of orders 5 and 6. We contemplate the same linear model and study its analysis in considerable details—with special emphasis on the nature of estimable parametric functions and also on the nature of error functions—in the presence of Row- and Column- Neighbor [RN- and CN-] Effects.


Supernatants (105,000 x g) of oxidized phosphatidylcholine (PC) liposomes contained higher levels of thiobarbituric acid-reactive substances, and caused greater metmyoglobin formation when combined with oxymyoglobin than those of controls (C) or PC plus tocopherol (PCT) (P<0.05). Products of PC liposome oxidation crossed dialysis membranes (mol wt cut-off = 500 Dalton) and accelerated the oxidation of oxymyoglobin more than C or PCT (P<0.05). The addition of known oxidation products of oleic acid and linoleic acid, fatty acids typical of PC, accelerated oxymyoglobin oxidation relative to controls (P<0.05). Results demonstrated that oxidation products of PC were prooxidative towards oxymyoglobin.


The key technology to realize intelligent unmanned coal mining is the strapdown inertial navigation system (SINS); however, the gradual increase of cumulative error during the working process needs to be solved. On the basis of an SINS/odometer (OD)-integrated navigation system, this paper adds magnetometer (MAG)-aided positioning and proposes an SINS/OD/MAG-integrated shearer navigation system. The velocity observation equation is obtained from the speed constraints during shearer movement, and the yaw angle observation equation is obtained from the magnetometer output. The position information of the SINS output is calibrated using these two observations. In order to improve the fault tolerance of the integrated navigation system, an adaptive federated Kalman filter is established to complete the data fusion of the SINS. Experimental results show that the positioning accuracy of the SINS/OD/MAG-integrated navigation system is 75.64% and 74.01% higher in the east and north directions, respectively, than the SINS/OD-integrated navigation system.

Amaximal independent set is an independent set that is not a proper subset of any other independent set. Jou and Chang determined the largest number of maximal independent sets among all graphs and connected graphs of order n, which contain at most one cycle. Later B. E. Sagan and V. R. Vatter found the largest number of maximal independent sets among all graphs of order n, which contain at most r cycles. In 2012, Jou settled the second largest number of maximal independent sets in graphs with at most one cycle. In this paper, we study the second largest number of maximal independent sets among all graphs of order n ≥ 5 with at most two cycles. We also characterize those extremal graphs achieving these values. Mathematics Subject Classification: 05C51


Two programs have been established at Virginia Tech with the purpose of engaging youth and showcasing agriculture. The Governor's School for Agriculture (GSA) program began in 2001, and has over 1,850 graduates. High school juniors and seniors from different areas of the Commonwealth's schools spend time on campus exploring the life sciences. The Virginia 4-H State Congress (4HC) is the premier, statewide annual 4-H event for outstanding teens, providing educational experiences to Virginia teens and helping them develop life skills and leadership abilities. Our extension group has focused on exposing teens enrolled in the GSA and 4HC to beef production, particularly bovine reproduction and reproductive biotechnologies. The 4-hr workshop, titled "Do it yourself cows", consists of a mixture of in-class presentations and hands-on laboratories relating to bovine reproductive anatomy and physiology and reproductive biotechnologies. The wet-laboratory consists of bovine female reproductive tracts anatomy dissection and artificial insemination and rectal palpation simulation with a mannequin, as well as demonstrations of equipment used in the field including, nitrogen tank for semen storage, ultrasound and microscope visualization of bovine embryos. The GSA "Bovine Reproduction" course is 4 days long and allows for in-depth discussion of factors influencing fertility and case discussions on beef reproductive management. The hands-on portion of this course is similar to the 4HC workshop, however students are able to perform rectal palpation and ultrasonography in cattle. So far, 40 students from the GSA and 80 students from the 4HC (2 GSA, and 4 4HC programs) have graduated in the course. At the completion of both programs, a survey was performed and 100% of the students considered the program positive and gained knowledge and interest in bovine reproduction. Furthermore, 20% of students from the GSA program developed a desire to pursue a career in livestock production, and 92% of 4HC students claimed to have learned information they can apply in their communities. Our data indicate that we were successful in engaging youth in animal agriculture, specifically beef production.


A dispute over price for retransmitting terrestrial channels between Terrestrial Television Systems and Cable TV System Operator(SO)s has been underway up to now since 2007 and expected to last unless there is a measure of extraordinary countermeasures. Thus, in this paper, we present a scheme for calculating the reasonable price on retransmitting terrestrial channels. Re-transmission price calculation scheme is presented in two ways. One is to calculate the price for the extent to which Terrestrial broadcasters and Cable broadcasters contribute, and the other is to calculate the price for terrestrial channels retransmitted by applying the method of Cable TV PP program fee basis. In addition, on profit-sharing scheme and criteria for program fee we present two ways of subscription, which are flat sum system and fixed rate system.

Predation rates on the eggs and young of forest-nesting songbirds typically rise in association with anthropogenic fragmentation, but predator responses depend on the spatial scale of disturbance, context, and predator assemblages present. For landscapes that are naturally fragmented, such as the boreal forest, our understanding of nest predation patterns associated with harvest may be further confounded by an additive response of nest predators to the loss of forest cover and the extension of habitat edges. We examined predation rates on artificial nests across a range of values for landscape metrics reflecting natural and anthropogenic forest fragmentation during two summers in boreal forest stands of western Newfoundland, Canada. Nest predation by gray jays (Perisoreus canadensis (L.)) increased significantly in logged areas, and gray jay abundance was positively linked to increasing amounts of logged edge; however, there was no response to the extent of natural openings suggesting that nest predation ...

Audit quality is the market value probability that the audit report will find opportunities in the financial statements, namely violations of the client's accounting system. In order to support audit quality, auditors must have a skeptical and competent attitude. The formulation of the problems studied in this study are: (1) How is the effect of professional skepticism of auditors on remote audit quality during the Covid-19 pandemic. (2) How does auditor competence affect remote audit quality during the Covid-19 pandemic. (3) How does professional skepticism and auditor competence affect remote audit quality during the Covid-19 pandemic. This study aims to determine the effect of professional skepticism and auditor competence on remote audit quality during the Covid-19 pandemic. The sample method used is simple random sampling method with a sample of 50 auditors at the Bandung City Public Accountant Office. The data analysis method used in this research is using multiple linear regression analysis method using SPSS 25 software. The results of this study indicate that professional skepticism (X1) and Auditor competence (X2) has a positive and significant effect simultaneously on quality of remote audits during the covid-19 pandemic (Y).


Author(s): Galanis, Panagiotis | Advisor(s): Moehle, Jack P. | Abstract: Earthquakes that have occurred recently across the globe in various countries including United States, Japan, New Zealand, Haiti, Turkey and Italy have brought into light the poor seismic performance of older-type, non-ductile concrete buildings. These buildings, mainly designed and constructed prior to 1980s, lack proper seismic detailing and may pose an unacceptably high seismic risk. Non-ductile concrete buildings pose one of the greatest seismic safety problems in the world due to the large amount of old buildings constructed in earthquake prone regions. It is indicative that according to the Concrete Coalition and the California inventory project there are 16,000-17,000 of these buildings in high earthquake risk counties of California. Many of these buildings have high occupancies, including residential, commercial and critical services. In case of a severe earthquake, the severe damage or even collapse that could occur in these buildings could result in large number of casualties. While engineers generally recognize that proactive steps are required to address the risk posed by these buildings, mitigation efforts are largely stymied by insufficient knowledge about the scale of the problem, insufficient tools to identify the truly dangerous buildings, high costs of strengthening, and owner resistance to pay for the strengthening with uncertain benefits. This study constitutes an effort to identify seismically hazardous concrete frame buildings through simplified methods that do not require complicated analysis. Three idealized concrete frame buildings with different heights are used as archetypes. The study attempts to link the collapse performance of these buildings with various structural deficiencies that appear commonly in older construction practice. To evaluate the performance of these buildings non-linear dynamic analysis for several far-fault ground motions is performed. The analysis considers nonlinearities associated with flexural yielding, shear and axial failure. The main deficiencies explored are development of weak story mechanisms due to strong column-weak beam designs, brittle shear or axial failure modes associated with inadequate column shear reinforcement detailing, and splicing and connectivity weaknesses between structural members. The results indicate that the suggested methods can be used to assess the collapse risk of older-type concrete buildings. The methods developed in the current study use simple engineering parameters such as column-to-beam strength ratio and column flexural to shear strength ratio to estimate the collapse risk of older type concrete buildings. A probabilistic approach is suggested that takes into account record-to-record variability and could accommodate as well uncertainty associated with structural properties and collapse modeling. In Chapter 7 the proposed methodology is evaluated by applying it to the three idealized buildings developed. The estimated probabilities of collapse calculated for each of the buildings according to the proposed methodology are compared with the values provided by sophisticated non-linear dynamic analyses. The results suggest that the proposed methodology successfully identifies deficiencies that are leading to high collapse potential and provides an effective tool in classifying collapse prone concrete frame buildings.


Gibberellins (GAs) are a class of phytohormones that impact various aspects of plant growth and development (reviewed in [Fleet and Sun, 2005][1]).

A review is provided of the conceptual design, prototype testing, production, assembly and installation phases of the two Megawatt scale photovoltaic plants constructed by ARCO Solar during 1982 and 1983: 1) The 1MW Hesperia (Lugo) PV power plant and 2) The Carrisa Plain 16.5 MW Power Plant (with an initial phase of over 6 Megawatts completed by Mid 1984). Design and construction details of each facility are provided. The use of large area integrated PV panels mounted on stateof-the-art heliostat type two-axis tracking structures resulted in a significant increase in annual energy production as compared to a fixed array.


Engineering properties of sweet oranges are very important to optimize the design parameters of processing equipment. The knowledge of engineering properties of sweet oranges is important for the design of grading, conveying, processing and packaging systems. Some engineering properties of grade I (>150 g), grade II (130-150 g), grade III (110-130 g) and IV (<110 g) sweet oranges were investigated. This study was undertaken to determine some important engineering properties such as axial dimensions, equivalent diameter, sphericity, surface area, individual fruit weight, volume, bulk density, true density, coefficient of friction and firmness of for the design of grading or sorting machine for sweet orange fruits. The shapes of the fruits were found to be round and the size of the fruits was characterized using length, width and thickness of fruits. The average volume of the fruits ranged from 177.86 to 100.76 cm; the individual fruit weight ranged from 175.52 g to 100.23 g and the average sphericity ranged from 0.976 to 0.970 whereas the range of fruit size was observed to be 67.64 to 54.56 mm from grade I to grade IV, respectively. The bulk density for the fruits varying from 564.47 kg/m to 533.06 kg/m; and the true density varies from 967.70 kg/m to 957.80 kg/m, respectively. The coefficient of friction of the sweet orange fruits on glass, GI (galvanized iron) sheet and plywood surfaces of four grades were ranges from 0.19 to 0.26. The force required to penetrate the fruits on stem, centre and tail ends of sweet orange fruits was found to 37.62, 26.29, 21.98 and 19.35 N, respectively. Maximum penetration force was found in grade I fruits at the tail end because of more compactness of the fruit and the minimum value was observed at centre portion of grade I fruits. Results shows that the four grades of sweet orange fruits were significantly different from each other regarding their engineering properties.

This article shows indicators of the socio-psychological climate in general secondary education institutions of the capital of Ukraine in the conditions of martial law in the second year of the war. The authors conducted a survey of 420 educators, the staff of thirteen schools of Kyiv. Three methods were used: the method «Analysis and evaluation of the social and psychological climate of the team» (L.M. Karamushka); a method of assessing the psychological atmosphere of the team (according to A.F. Fiedler) and a questionnaire adapted by the department staff, containing 15 questions that characterize the attitude of teachers to work. The emotional attitude of teachers to the conditions of job was analysed; psychological atmosphere in the team; command settings etc. Four factors are key to establishing a favourable climate in schools: 1) relations with the principle, 2) relations with colleagues, 3) greater trust to the teacher who strives for self-realization, 4) clear organization of management activities. The teacher needs a higher level of trust. Most of all, teachers want to be able to demonstrate their own business qualities and build a clear relationship with the manager. It is important for teachers to be able to choose the directions of their activity, the content of their work, the ability to set the sequence of work at their own discretion within the defined terms, and to choose the method and time of their execution. During martial law, educators need more support and a sense of protection of their rights.


In this study, a novel algorithm to estimate the optimum value of the fuselage drag coefficient is designed by integrating the artificial neural network (ANN) which is an artificial intelligent method into the algorithm of simultaneous perturbation stochastic approximation (SPSA) which is a fast method. SPSA converges to the optimum value for solution very fast. However using SPSA alone requires a function of problem to estimate the optimum solution. On the other hand, ANN is able to estimate the solutions for the problem without need of its any objective function. However ANN needs a certain data set to be effectively trained. Also, the best ANN architecture which accomplish with different data sets of problem may alter. Thus, ANN architecture alone is not adequate for estimating the best result for each different data set. The main target of this study is making SPSA able to be applicable for the problem that has not any objective function by using training capability of ANN. For this purpose, initially, ANN is trained by the data of fuselage drag coefficient obtained by previous experimental results conducted in wind tunnel and varies depending on the geometry of fuselage. Thus, ANN becomes capable to estimate the fuselage drag coefficient for each parameter values of the fuselage shape. Therefore, ANN estimates the fuselage drag coefficient with respect to inputs without the requirement of any experimental computations. Note that ANN does not estimate the optimum value as output but estimates the output regarding to the inputs. The ANN is integrated into the SPSA to fulfill the need of cost function for SPSA. More clearly, the new algorithm evaluates ANN to estimate the fuselage drag coefficient with respect to inputs while evaluates SPSA to estimate the optimum inputs for the optimum fuselage drag coefficient. Through integrating the trained ANN into the SPSA, an effective and novel algorithm estimates the fuselage drag coefficient fast and accurately without defining an objective function is improved.

We report here on a method to functionalize silicone surfaces, which is based on the deposition of silicone-containing amphiphilic block copolymers from a colloidal water–ethanol dispersion. Using cross-linked silicones (Sylgard 184) as substrates, copolymers composed of two poly(glycerol monomethacrylate) (PGMMA) terminal blocks and a central poly(dimethylsiloxane) (PDMS) block can be effectively deposited when the PDMS content is ≥46 wt%. (≥65 mol%); the deposition provides smooth and stable surfaces, which significantly affected the protein adsorption behaviour of the substrate, suggesting a possible application in biomaterial coating. In air, the block copolymer surface films underwent a reorganization, which differs from the classical hydrophobic recovery of silicones and may be related to a disordered folding of lamellar structures. This led to a predominant surface coverage by thin, possibly monomolecular layers, which displayed a non-restructuring polar surface. However, as a consequence of the reorganization also larger aggregates were produced, albeit in relatively small numbers; these aggregates underwent a progressive hydrophobization (in this case a hydrophobic recovery) and probably dominated the contact angle behaviour of the material. In summary, the colloidal deposition of amphiphilic silicone-based block copolymers successfully modifies the surface properties of silicone substrates; however, attention must paid to reorganization phenomena in order to maximize the stability of the coating.


Will there be enough land to feed and clothe the world properly? Depending on one's level of social perception and on his commitment to economic logic, there are a variety of answers to that question. The extreme answers are: (1) there has never been enough land, and (2) there has always been enough. Many of us who are committed to the logic of economics, in the train of Adam Smith, David Ricardo, and more recent socalled land economists (now resource economists), have often been fascinated by the economizing exercise (allocating scarce resources to competing ends) when applied to the land factor. In particular, I often become engrossed as a traditionaleconomist (I don't classify myself among the professional resource economists) in the argument over the demand for and supply of land. The latest dimension, of course, is the current spate of land use proposals, legislation, and regulations. I shall be more concerned with the generic argument over land supply for future food and fiber needs rather than


Current guidelines recommend using ticagrelor in patients with acute coronary syndrome. Ticagrelor is predominantly metabolized by CYP3A4 and to a lesser extent by CYP3A5. CYP3A4*22 allele and the CYP3A5 expressor status influence the metabolization of ticagrelor, increasing plasma concentration and platelet inhibition. Nevertheless, little is known about the impact of the CYP3A4*22 allele or CYP3A5 expressor status on clinical outcomes in ticagrelor treated patients.

 Our study aims to assess the effects of the CYP3A4*22 allele and CYP3A5 expressor status in patients with STEMI and treated with ticagrelor, with regards to clinical outcomes and the clinical side-effect dyspnea.

 Patients from the POPular Genetics trial treated with ticagrelor were genotyped for the CYP3A4*22 and CYP3A5*3 alleles. Patients were divided into two groups based on their CYP3A4 (*22 carriers vs. *22 non carriers) and CYP3A5 status (expressor vs. non-expressors). The primary thrombotic endpoint was a composite of cardiovascular death, myocardial infarction, definite stent thrombosis and stroke. The primary bleeding outcome consisted of PLATO major and minor bleeding. The key secondary endpoint was clinically relevant dyspnea. The follow-up duration was one year.

 A total of 1,281 patients with ST-elevation myocardial infarction (STEMI) were used for the analyses. In the first analysis, CYP3A4*22 carriers (n=152) versus CYP3A4*22 non-carriers (n=1,129) were not found to have a significant correlation with the primary thrombotic outcome (1.3% vs. 2.5% adjusted hazard ratio 1.81 [0.43–7.62]) or the primary bleeding outcome (13.2% vs. 11.3% adjusted hazard ratio 0.93 [0.58–1.50]) (See Figure 1 and 2). CYP3A5 expressors (n=196) versus non-expressors (n=926) did not show a significant difference for the primary thrombotic outcome (2.6% versus 2.5% adjusted hazard ratio 1.03 [0.39–2.71] or the primary bleeding outcome (12.8% versus 10.9% adjusted hazard ratio 1.13 [0.73–1.76]). With respect to dyspnea, no significant difference was observed between CYP3A4*22 carriers versus CYP3A4*22 non-carriers 44.0% vs. 45.0%, risk ratio 1.04 [0.45–2.42] or CYP3A5 expressors versus CYP3A5 non-expressors 35.3% versus 47.8% risk ratio 0.60 [0.27–1.30].

 In STEMI patients treated with ticagrelor, CYP3A4*22 carriers and CYP3A5 expressors did not affect clinical outcomes with regards to thrombotic events, bleeding rate, or the side-effect dyspnea.

In this note, the control problem for discrete-time hidden semi-Markov jump systems is investigated under the situation that the system modes are unavailable directly. Compared with the previous results, the case when both system modes and states are immeasurable simultaneously is fully considered and an observer-based control scheme is established for discrete-time hidden semi-Markov jump systems. The random parameters of the systems are subject to a two-layer stochastic process and the underlying stochastic process is assumed to be subject to a semi-Markov process. Furthermore, a novel switched Lyapunov function is used, which may be monotonically increasing or decreasing at the instant of nonmodal switching. Moreover, by means of the stochastic stability theory and semi-Markov kernel method, some novel sufficient conditions ensuring $\sigma$-error mean-square stability of the closed-loop system are obtained by a power term reduction method. Finally, an illustrative example is introduced to verify the feasibility of the proposed control method.


assemblage showcases covers, columns and illustrations from Flechtheim's house organ Der Querschnitt, a less-political, more pop-culture leaning Berlin counterpoint to Herwarth Walden's Der Sturm. The museum's archival impulse extends through a particularly unusual and compelling ode to Renée Sintenis, incorporating tiny, Passbild-sized vernacular photos of the artist and her wire-haired fox terrier, which make a lovely complement, and invites similar close inspection of Sintenis's palm-sized bronzes of foals and dogs. The mix of tension and influence is perhaps expressed best again by Belling in his 1929 naturalistic study of Max Schmeling, the heavyweight boxing champion of the world – who was also friends with Flechtheim. Sports as an acceptable theme had, since the beginning of the 1900s, already crept into modernist paintings by Max Liebermann and Robert Delaunay. As opposed to Arno Breker, Belling's interest in the physiques of athletes was simply an acknowledgment of a more mediated modern world. There is not a designated official catalogue for the exhibition, but there is an excellent companion volume of essays, Sprung in den Raum: Skulpturen bei Alfred Flechtheim (in German) which includes substantial chapters about the featured artists, including chapters by Helen Shiner, the Oxford-based art historian compiling the Moissey Kogan catalogue raisonné, and Arie Hartog, director of the Gerhard-Marcks-Haus in Bremen. Curated by Dr Julia Wallner, Kolbe Museum director.


For the purpose of improvement in resolution of force gradient and mass detection in atomic force microscope (AFM), we are developing cantilevers measuring from 100 nm to several microns. We succeeded in fabrication of single crystal Si cantilever with several microns size and measurement of its mechanical characteristics. Silicon-on-insulator (SOI) wafer is used for the fabrication. Fabrication is based on three anisotropic etching by KOH and two local oxidation processes of Si. Without depending on precision of lithography technique, triangular shaped cantilevers measuring several microns with tetrahedral tips on their ends are fabricated with high uniformity. The thickness of the cantilever is chosen from 20 nm to 120 nm. Typical spring constant, resonance frequency and Q factors of the single-crystal Si cantilevers are several N/m, 1 to 10 MHz and around 10/sup 4/ in vacuum, respectively. The density of the cantilever is up to 10,000 cantilevers/mm/sup 2/. We aim to scan an area of up to a few mm/sup 2/ simultaneously with this multi-probe cantilever array.


Received Apr 7, 2020 Revised Apr 8, 2020 Accepted Sept 12, 2020 Multilingualism is the ability of someone to operate more than one language for communication. Atambua people are multilingual since they have more than one language background, and it makes them difficult in speaking English. This study aims to Analyze the English Oral Proficiency (EOP) of the Atambua students with multilingual background. It is a descriptive qualitative research involving multilingual Atambua students who also speak English. 10 participants were chosen from 200 participants in total through questionnaire developed by the researcher to know their multilingual background. EOP in form of monologue was employed to the students to know their level using scoring rubric by Brown (2001). Then, analysis was done to see the relation of their level of EOP with their number of language use and age of their English acquisition or learning. The result of this study showed that 2 students with 3 languages use have 3,0 and 3+ levels, (able to participate effectively in formal and informal situation, as well as the professional topics). 5 students with 4 languages use have various level, ranging 1+ (able to satisfy limited social demands) to the 3+ level. 1 student with 5 languages was in level 1+, and 2 students mastering 6 languages were in level 1+ and level 2 (able to satisfy routine social demands). 2 students learned English before 10 years-old, and their EOP level was 3+. 8 other students learned English in their 11 up to 14 years-old. Interesting phenomenon found that only 1 out of 8 students with 3 languages use get the highest level (3) even she learns English over golden age. It indicates that the result of the research is in line with the previous theory stated that multilingual person will face difficult in learning English, Bialystok(2001).


The purpose of this study was to determine the relationship between job satisfactions and teachers' mobility in Momba District, Tanzania. The study used a survey research design. The target population of the study was 185 teachers from eleven randomly selected schools from whom the sample of 126 teachers filled the questionnaire. The analysis of data involved binary logistic regression. The study revealed that teachers who were not satisfied with distance to places where a good houses are found were more likely to be mobile compared to those who are satisfied with the distance to good houses. Similarly, teachers who were not satisfied with the distance to a place where higher education is available are more likely to be mobile compared to those who are satisfied with the distance to a place where higher education is available. The rest of independent variables did not affect teachers' mobility. The study recommended that the management of the Momba District Council in collaboration with local communities should improve conditions of living in terms of constructing attractive houses, which will extinct teachers' desires to move to schools located near good houses.


This chapter focuses on Harriet Jacobs's Incidents in the Life of a Slave Girl (1861) and Hannah Crafts's The Bondwoman's Narrative (written circa 1858 and published 2002). Although Jacobs and Crafts depict their personal experiences in slavery, they infuse their stories with gothic tropes to employ the power of fictionality. Gothic damsels in distress are beset by lascivious slaveholders and traders who are cast as monstrous villains. While the damsels are haunted by the law's pronouncement of them as merely property, they find refuge in haunted spaces, thereby claiming a different kind of ownership. This spectral possession is then doubled by the authors, Jacobs and Crafts, who shape their narratives as literary property they themselves can own.


Maintaining tool availability is the key to ensure machining quality. To evaluate tool availability so as to improve its utilization, the tool diagnosis models for tool-remaining-useful-life (RUL) estimation and tool-state classification are required. These models need sufficient samples to cover all the variations of tool coating and chip friction. However, in general, it is not easy to collect enough samples in the early stage. This issue will delay the readiness of the tool diagnosis models. The purpose of this letter is to propose a gradual refreshing scheme for modeling, running, and refreshing tool diagnosis models. In addition, a sample extension method is presented for reducing modeling time and enhancing accuracy of tool-state classification. The examples of engine-case machining are adopted in this letter to illustrate how the system works for estimating tool-RUL, classifying tool-states, and further, improving tool utilization.


This study realizes a new solar-power generation system that can complete the global maximum power point tracking (GMPPT) control under uniform irradiation and partial shading conditions (UIC and PSC, respectively). The MCU of the proposed system calculates the IGMPP of the photovoltaic (PV) module to accurately execute GMPPT on the basis of the PV module current (Ipv), power (Ppv) and temperature trend line slope (dIpv/dPpv). The microcontroller unit can then confirm whether the PV module suffers from shading according to the slope (dIpv/dPpv) and immediately executes the PSC mode control strategy to calculate the VGMPP of the PV module, thereby accurately tracking the GMPP. The proposed algorithm is compared with the existing methods. Such model is then practically experimented from the irradiance levels of 1000 W/m2 and under PSC. Experimental results confirm that the performance of the algorithm is better than those of the traditional hill-climbing algorithm and perturbation and observation methods.


A complementary pair of planar-power MOSFETs has been developed, each of which has drain breakdown voltage as high as 250 V and 12-A current capability. These devices have field plates on the ion-implanted gate offset region to realize high-breakdown voltages and large current capabilities. The field distribution behavior of a field-plated high-voltage MOSFET and a non-field-plated device are compared. In this procedure, the first-order theory of pinchoff voltage of the offset region, the most important parameter for a planar-power MOSFET, is derived for high-voltage and high-current capability design. Experimental results to support the usefulness of a field plate for improving breakdown voltage and current capabilities are obtained and discussed. Finally, future possible developments of these devices, such as high-voltage and high-current approaches, are described and a new type of device structure is proposed.


Social entrepreneurs face unique challenges in their dual pursuit of social and financial value creation to address pressing societal problems. While social entrepreneurs' behaviour and actions have been highlighted as an important source of creativity and innovation, this issue has largely been underresearched in the field of entrepreneurship. This paper explores the role of social entrepreneurs' bricolage behaviour in enabling their enterprises to scale their operations. The authors test their hypothesis on a unique database of 123 social enterprises using an online survey. They find a positive relationship between entrepreneurial bricolage and the scaling of social impact. The paper concludes with study implications, post hoc analyses and limitations and directions for future research.


At present, the identification of psychological factors as a determinant of the illegal behaviour of adolescents is of great importance. The mental model allows explaining and predicting the behaviour of other people and reflecting one's own mental inner reality. The study of the mental model in adolescents with delinquent and law-abiding behaviour using specially designed narratives provided us with the opportunity to analyse the understanding by adolescents, who have committed and not committed crimes, of the mental states of their own and that of another person, as well as the causes of such states in the process of social interactions. The ability to understand the mental world is paramount and necessary for understanding social interactions, for the correct formation of motives and semantic attitudes of the individual. The results of an empirical study allowed us to confirm the hypothesis that the deficit of the mental model is formed in the family; it is associated with the personality characteristics of the adolescent and, obviously, affects the formation of delinquent behaviour.

Minimal invasion has already come to treatment of venous disease. Catheter-directed thrombolytic therapy is now routine, and indications for its application are continually broadening. However, valve repair, valve transplantation, and other methods of restoration of venous competence by minimally invasive techniques are futuristic at best and perhaps impossible at worst. Kandarpa, in describing future directions in vascular and interventional radiology research, quoted Winston Churchill, and his statement is applicable here.1 Sir Winston said "the empires of the future are the empires of the mind." His statement can guide us in visualizing the future of minimal invasion in clinical care of patients with venous insufficiency. Fundamental Problems of Venous Insufficiency


Effects of cyclic rapid thermal annealing of metalorganic vapor-phase epitaxy grown single-crystal CdTe layers on (211) Si substrates are investigated. Typically, 5-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>-thick CdTe layers were grown directly on the Si substrates after some substrate pretreatments but without growing other intermediate layers, and annealed <italic>ex-situ</italic> in a flowing hydrogen atmosphere. We varied the annealing temperature from 500 °C to 1000 °C, annealing times from 30 to 90 s, and the number of annealing cycles from 1 to 9. Improvement in the crystal quality was confirmed by the full-width at half-maximum values of double-crystal rocking curves for the annealing temperatures between 800 °C and 900 °C. Furthermore, the 4.2-K photoluminescence measurement and the current–voltage measurements revealed that the conductivity type and the resistivity of the crystals do not change after annealing.


The paper describes a different approach to software reliability growth modelling which should enable conservative long term predictions to be made. Using relatively standard assumptions it is shown that the expected value of the failure rate after a usage time t is bounded by: /spl lambda/~/sub t//spl les/(N/(et)) where N is the initial number of faults and e is the exponential constant. This is conservative since it places a worst case bound on the reliability rather than making a best estimate. We also show that the predictions might be relatively insensitive to assumption violations over the longer term. The theory offers the potential for making long term software reliability growth predictions based solely on prior estimates of the number of residual faults. The predicted bound appears to agree with a wide range of industrial and experimental reliability data. It is shown that less pessimistic results can be obtained if additional assumptions are made about the failure rate distribution of faults.

The system aims to determine the age of a tomato and to classify its maturity level to be able to sort out the crops that are ready for distribution for a better quality of products. Using Image Processing, the system will detect the dominant color of the tomato from Green, Orange, and Red and from then the system will be able to provide the age of the tomato whether it is on its best age for picking.


The methanolic extracts of fruits of a promising medicinal plant Morinda pubescens J.E.Smith were screened for their antiradical properties using ascorbic acid as standard antioxidant. Free radical scavenging activity of methanolic and aqueous fruit extract was evaluated using 1,1-diphenyl2-picrylhydrazyl (DPPH), nitric oxide (NOX) and ferric reducing antioxidant power (FRAP) assay. The overall antioxidant activity of methanolic extract of mature fruits was the stronger, than the aqueous extract. It reveals that the consumption of these fruits would exert several beneficial effects by virtue of their antioxidant activity.

Although recent test automation practices help to increase the efficiency of testing and mitigate the cost of regression testing, there is still much manual work involved. Achieving and maintaining high software quality today involves manual analysis, test planning, documentation of testing strategy and test cases, and development of test scripts to support automated testing. To keep pace with software evolution, test artifacts must also be frequently updated to stay relevant. Current test automation is unable to generalize across applications and is unable to mimic human intelligence. As such, there is a significant gap between the current state of practice and a fully automated solution to software testing. This paper investigates a practical approach that leverages artificial intelligence (AI) and machine learning (ML) technologies to generate system tests based on learning testing behavior directly from human testers. The approach combines a trainable classifier which perceives application state, a language for describing test flows, and a trainable test flow generation model to create test cases learned from human testers. Preliminary results gathered from applying a prototype of the approach are promising and bring us one step closer to bridging the gap between human and machine testing.


With the increased popularization of deconstruction in recent years, the notion of translator-orientedness is gathering unprecedented prevalence in the marketplace of translation studies in China. The author of the thesis, armed with Umberto Eco's reasoned reflections on Hermeticism and Gnosticism with their impacts and challenges imposed on text theory, has tentatively proposed that the surfacing of the phenomenon with no less visibility in translation can hinder the rational construction of translation studies.

SD mice were randomly divided into two groups and given Rg1 and PEG-Rg1 by intravenous injection respectively. Their samples of blood and organ tissues were taken at different time points. The content of Rg1 in samples were determined by UPLC and used as indicator to observe the targeted distribution of Rg1 in mice tissues.

RESULT
The AUC of ginsenoside Rg1 in tissues of the Rg1 group were in the order of liver, kidney, lung, heart and spleen, with the liver targeting coefficient was of 2.01. While the AUC of ginsenoside Rg1 in tissues of the PEG-modified group were in the order of the kidney, liver, lung, heart, spleen, with the liver targeting coefficient was of 9.21.

CONCLUSION
PEG modified Rg1 can increase Rg1's targeting selectivity to the liver, kidney and lung in mice.


PT. X is an Indonesian company that is involved in construction and now is
working on construction project in West Surabaya. Observation result showed that
the majority of accidents occured due to unsafe actions. This study was conducted
to analyze the correlation of basic cause factors and management factor with
unsafe actions of finishing construction worker on the building project at PT. X in
West Surabaya. Basic cause factors such as individual characteristics (age,
education, years of work, work experience), work stress, controlling and
management factor is work instruction.
This was an observasional study with cross sectional design. The sample was
63 workers from 74 finishing workers using simple random sampling technique.
Data was collected through observation and questionnaires to workers.
Correlation was tested using the Spearman test.
The result showed that most workers have moderate and low unsafe actions
as much as 38,1%. There was a relation between basic cause with unsafe actions
include work experience (sig=0,000), knowledge (sig=0,038), work stress
(sig=0,023) and controlling (sig=0,000). There was a relation between
management factor that is work instruction (sig=0,000) with unsafe actions.
It can be concluded that the longer work experience the lower unsafe actions,
the better knowledge the lower unsafe actions, the higher work stress the higher
unsafe action, the better controlling the lower unsafe action and better work
instruction of worker the lower unsafe actions. Unsafe action can be reduced by
routine inspection in project area by management, increasing knowledge with
giving training of safety and health environment, managed of workload, job hours
and periodically evaluation of work instruction


The main purpose of this study was to analyze the new public management reforms practiced by some of the developed countries and determine their applicability to Nepal. New Public Management (NPM) was defined as cost cutting and downsizing, introducing agencies, separation of purchaser and provider, decentralization of management
authority, performance management, introduction of market mechanisms, changes in personnel systems and quality and customer responsiveness. The term 'applicability' was determined by the perceived usefulness of NPM to stakeholders. The main focus of this research was to find an answer to the pertinent question - Is NPM applicable to Nepal? This research explored the political and bureaucratic environment inherent in Nepal, examined the influence of political and bureaucratic factors to the applicability of NPM and suggested recommendations for future reform in Nepal.


The disease only appears after normal parturition or abortion, and during the first few days immediately succeeding delivery. Parturition may occur spontaneously in a perfectly regular and easy manner, and nevertheless be followed by fatal metritis as a consequence of infection. Usually, however, the labour has been difficult, and the after-birth, or portions of the foetal membranes, have been retained. Parturition supplies trauma which lowers defence and assists the invasion of micro-organisms. Infection with micro-organisms is, therefore, the essential cause. Other conditions simply favour invasion and lower the resistance of the host. Moreover, the subsequent course is in part due to the variety of infective agent. Several different species of bacteria are potential invaders. While in veterinary medicine many studies have been made, regarding these bacterial invaders still much remains to be determined. The most frequent agents are streptococci, colon bacilli and various putrefactive bacteria.


Based on dissimilar materials of 301L/TA2, the effect of laser offset and copper intermediate layer on welded joints was investigated. First, the process optimization of laser offsets indicated that the tensile strength of welded joint without intermediate layer was reached to the highest value when the laser was applied on the TA2 side. On the other hand, the tensile strength of welded joint with intermediate layer performed well when laser was applied in the middle position. Then, microstructural characterization and mechanical properties of welded joints were observed and tested. Based on eutectic reaction and peritectic reaction: TiFe and TiFe2 compounds were produced for welded joint without intermediate layer. Cu-Fe solid solutions and Cu-Ti compounds were generated when copper was used as the intermediate layer. The maximum tensile strength of welded joint with and without copper intermediate layer were 396 and 193 MPa, respectively. Finally, fracture mechanism of 301L/TA2 welded joint was studied: Fe-Ti compounds caused brittle fracture of welded joints without intermediate layer; brittle fracture took place in rich copper and Cu-Ti compounds area of welded joints with copper intermediate layer.


Fission cross section of short‐lived minor actinides is of prime importance for the incineration of minor actinides in high and thermal neutron fluxes. But due to the shortness of their half‐lives, measurements are difficult to handle on these isotopes and the existing data present some large discrepancies. An original method has been developed, in the framework of the Mini‐INCA project at ILL, to measure the fission and capture cross sections of minor actinides with low error bars associated even for short‐lived isotopes. This method lies on a quasi on‐line alpha‐ and gamma‐spectroscopy of irradiated samples and on the use of fission micro‐chambers. Coupled to a very powerful Monte‐Carlo simulation, both microscopic information on nuclear reactions (total and partial cross sections for neutron capture and/or fission reactions) and macroscopic information on transmutation and incineration potentials could be gathered. In this paper, the method is explained in its originality and some recent results are gi...


Abstract In this paper, an overview of storm waves associated with intense weather systems affecting the east and west coasts of Canada is presented. The paper presents the wave climatology of the east and west coasts in terms of the 100‐year significant and maximum wave heights and further analyses the directional distribution of wave heights at selected locations in the Canadian east and west coasts offshore. The paper also analyses wave hazards associated with storm waves in the Beaufort Sea as well as the Canadian Great Lakes region. A section on ocean wave modelling provides a brief history of the development of ocean surface wave models and its present status. The paper further considers the impact of climate change scenarios on wave hazards and finally examines mitigation measures in terms of wave products available from operational wave models and related wave climatology.


Along with other sectors and fields, art environments were also faced shutdowns during the COVID-19 Pandemic, which was caused by a type of coronavirus that affected the whole world and resulted in a new period during which people had to work from home and adjust their lives accordingly. In this period, many of the exhibitions were continued online. The prolongation and uncertainty of the period made it necessary to present online exhibitions with more realistic solutions. And this created a new trend towards virtual reality applications that offer closest experience to reality. Virtual reality exhibitions became a notable alternative to online exhibitions in a lot of respects such as allowing typical curatorial arrangements as well as adding digital methods, and making the audience feel like they are actually visiting an exhibition. However, it obviously causes overcrowding and loss of aura as a result of a phenomenon based on excessive display in structures open to the participation of everyone. In order to preserve the aura of art and exhibition and to maintain its compatibility with new technologies, it's necessary to introduce new curatorial understandings, new aesthetic perceptions, and new quality elements. In this study, the existence of art exhibitions in online environments, especially during the pandemic, will be evaluated within the context of qualitative descriptive analysis.


In this research, we developed a process that helped students connect
cell and molecular biology concepts with problems in context of their lives.
Specifically, we supplemented traditional teaching with problem, project and
inquiry based laboratories, without changing the structure of the mandated
biology curriculum. We ran the process twice, following the classroom based
action research model. Our initial foray exhibited better student-developed
projects and a modest improvement of test grades. Second time we compared
changes in problem solving skills, attitude toward reading, writing and problem
solving and improvement of traditional test grades from the beginning and end
of the school year. This process made the biological concepts so interesting
that by the end of the year nearly all students significantly (t(55) = -8.95, p ≤ 0.05) improved problem-solving
skills and some students went further to develop and solve independent
inquiries. They also exhibited improved attitude towards reading, writing and
problem solving. However, we didn't observe any causal relationship between
improvement of problem solving skills and test grade, since its trend showed
little difference between first and second trial.


Haze is a natural meteorological phenomenon and happens when a large number of dried particles float and spread in the sky. The process occurs because of the law of advection, when wet air masses meet up with dry air masses they form an inversion layer of compressed the air, that looks like fog but is not actually a fog, because the air contains aerosol particles such as dust or smoke. This haze phenomenon is usually found in an urban city due to the impact of greenhouse-gases emissions from motor vehicles and industrial pollutants. The purpose of study was to find out the condition of the air pollution in Jakarta, a biggest urban city, by looking at the amount of haze events that have occurred. Using surface air observation data processing and data layers of the upper air, the frequency of haze events in 2016 were calculated. The minimum air temperature data was the main parameter used and all statistics were performed using Microsoft Excel. In addition, to find the height of the atmospheric inversion layer formed, we used data concerning the upper air layer and processed with RAOB (Rawinsonde Observation Program). Taken together, the amount of haze in Jakarta was found to be equivalent to the increasing number of pollutants in the city.Haze is a natural meteorological phenomenon and happens when a large number of dried particles float and spread in the sky.

Background: Pollution of aquatic ecosystems with heavy metals leads to decrease of the biodiversity and accumulation of toxicants in the food chain. Species of the genus Scenedesmus are sensitive indicators of environmental changes and have been used for the evaluation of risk factors for contamination of aquatic ecosystems. The microalga Scenedesmus incrassatulus can remove chromium and cadmium from the growth medium. Also, mammalian cell lines are another type of test system that has been used to study the mechanisms of heavy metal toxicity. However, little is known about the sensitivity and potential application of different human cell lines for bio-monitoring of heavy metal contamination. Aim: To investigate the toxicity of increasing concentrations of cadmium, nickel and lead on the green microalga Scenedesmus incrassatulus and the human cell lines HeLa, A549, FL, and Caco-2. Materials and Methods: To evaluate the toxic effects of Cd, Ni, and Pb, two test systems were used: an algal culture of S. incrassatulus and four human cell lines. For the algal system, the growth of the algae and the features such as "cell number in the coenobium/single cells", "position of the inner cells in the coenobium", and "shape of the peripheral cell", were assessed. For the human cell cultures, the methyl-thiazol-tetrazolium (MTT) and neutral red assays were performed. In both the systems, the effects were measured at different time points (24, 48, and 72 hours) of treatment. Results: The experimental observations showed that lead exposure in maximal permissible levels (MPL) inhibited the growth of the green algae S. incrassatulus, while cadmium had a stimulating effect even at lower test concentrations. Cadmium and nickel treatment affected the morphological features "cell number in the coenobium/single cells" and "position of the inner cells in the coenobium". Regarding "shape of the peripheral cell", lead had the most significant effect after 24 h of treatment, which was expressed in reduction of the type "incrassatulus" compared to the type "obliquus". Cytotoxic effects of the heavy metals were also observed for all tested human cell lines. HeLa, FL and Caco-2 were most sensitive to cadmium compared to lead, while A549 cells showed equal sensitivity to all three heavy metals. Conclusion: The reported data presented specific impacts on the studied parameters for both the test-systems. The present study concluded that the green alga S. incrassatulus could be used as an effective test system for the biomonitoring of lead pollution. The cell line A549 can serve as a sensitive test system for the presence of cadmium, nickel and lead. TOXICOLOGY AND FORENSIC MEDICINE


Urbanization has been contributing more in global climate warming, with more than 50% of the population living in cities. Rapid population growth and change in land use / land cover (LULC) are closely linked. The transformation of LULC due to rapid urban expansion significantly affects the functions of biodiversity and ecosystems, as well as local and regional climates. Improper planning and uncontrolled management of LULC changes profoundly contribute to the rise of urban land surface temperature (LST). This study evaluates the impact of LULC changes on LST for 1997, 2007 and 2017 in the Rajshahi district (Bangladesh) using multi-temporal and multi-spectral Landsat 8 OLI and Landsat 5 TM satellite data sets. The analysis of LULC changes exposed a remarkable increase in the built-up areas and a significant decrease in the vegetation and agricultural land. The built-up area was increased almost double in last 20 years in the study area. The distribution of changes in LST shows that built-up areas recorded the highest temperature followed by bare land, vegetation and agricultural land and water bodies. The LULC-LST profiles also revealed the highest temperature in built-up areas and the lowest temperature in water bodies. In the last 20 years, LST was increased about 13oC. The study demonstrates decrease in vegetation cover and increase in non-evaporating surfaces with significantly increases the surface temperature in the study area. Remote-sensing techniques were found one of the suitable techniques for rapid analysis of urban expansions and to identify the impact of urbanization on LST.

Graphical design methods for various types of closed circuit grinding systems including plural mills and classifiers are dealt with on the basis of mathematical analyses. The systems involving one mill together with single or plural classifiers (Figs. 3 and 7) have the same characteristics as the standard type (Fig. 1) except for the circulating load, which should be equal to that of the standard type plus one if the same product size distribution is required. This means that those types are superior to the standard type with respect to capacity, while, systems involving two mills (Figs. 4 and 6) are characterized by alterations in the size distribution of the finished product. Figs. 2 and 5 are useful for designing those circuits without tedious calculations.


Abstract A limitation of oxide cathode is the high current density, caused by low electrical conductivity of an emitter layer. This limitation can be overcome by increasing the conductivity, and uniform dispersion of Ni powder and pore agent could be achieved by using the screen‐printing method. This new cathode has shown not only high current density reliability but also improved performance characteristics and as such given the name "Multi‐Function cathode". It is expected to be a good replacement of the impregnated cathode.


: The segmentation of the spine can be an essential step in computer-aided diagnosis. Current methods aiming to handle this problem generally employ an explicit model of some type. However, to create an adequately robust model, a high amount of properly labeled diverse data is required. This is not always accessible. In this research, we suggest an explicit model-free algorithm for spine segmentation. Our approach utilizes expert algorithms that are built on medical expert knowledge to create a spine segmentation from thoracic CT scans. Our system achieves an IoU (intersection over union) value of 0.7103 ± 0.051 (mean ± std) and a DSC (Dice similarity coefficient) of 0.8295 ± 0.0343 on a subset of the CTSpine1K dataset.


A Rankine bottoming cycle for waste heat recovery from diesel engines used in long-haul trucks has the potential of improving peak fuel efficiency by up to 15% over a typical duty cycle. Of all Rankine cycle system components, the expander is the most important and the most difficult to design for high efficiency. The design and preliminary evaluation of a nominal 40 hp multi-vane rotary expander developed for this application are described. Key features of a multi-vane expander for the diesel truck engine include: ruggedness and close match to diesel speed characteristics, high efficiency over a wide range of conditions, adaptability to a simplified control system, and a firm basis of hardware experience. Potential advantages of the expander for the diesel engine bottoming cycle include the elimination of a high-speed turbine/gearbox combination and over 80% isentropic engine efficiency. Areas requiring additional work include additional cycle analysis to quantify the best cycle and components, development of an expander for this specific application, and integration and testing of an entire Rankine system on a diesel engine.


The existing Timed Influence Nets (TIN) framework is assumed that delays on arcs are constant. This constraint may turn out to be unrealistic in many real world situations. The proposed parametric enhancements would overcome the above limitation, and enable a system modeler to specify stochastic delay in a dynamic uncertain situation that the existing TIN fails to capture. The new class of models is named Stochastic Timed Influence Nets (STIN). Both TIN and STIN provide an easy-to-read and compact representation to several time-based probabilistic reasoning paradigms.

Abstract Three bidentate salicylaldimine nickel complexes containing different long-chain alkyl groups in their ligand backbone were synthesized in good yield. All the bidentate salicylaldimine ligands and their nickel complexes were fully characterized by FT-IR, 1H NMR, UV spectroscopies, and mass spectrometry. Three bidentate nickel complexes were evaluated as catalyst precursors in ethylene oligomerization. Upon activation with methylaluminoxane (MAO), the catalytic activity was 5.75 × 105 g/(mol Ni·h) and the oligomers were mainly butenes (52.10%) and octenes (32.63%) for bidentate nickel complex with 1-tetradecyl as core in the ligand backbone (R14-complex) using toluene as solvent. However, bidentate nickel complex with 1-octadecyl as core in the ligand backbone (R18-complex) produced mainly octenes (59.38%) and C10 + olefins (29.01%) and the catalytic activity was 2.23 × 105 g/(mol Ni·h). After activation with ethylaluminum sesquichloride (EASC) in toluene, three nickel complexes yielded mainly C10 + products which contained Friedel-Craft alkylated-toluene, and their catalytic activities were above 1.5 × 106 g/(mol Ni·h). For the bidentate salicylaldimine nickel catalysts with hyperbranched molecules as ligand backbones, the solvent and the reaction conditions had a large effect on catalytic activity as well as oligomerization distribution except the structure of the catalyst and the co-catalyst.
