Opis:
This paper describes some studies on the development of shape memory alloy (SMA) coresheath friction yarns. SMA wires for actuating purposes were utilised as a conductive element in the core-sheath friction yarn. A DREF 3000 friction spinning machine was used to produce the yarns. The conductive yarn was spun with the SMA actuator wire at the core and 100% cotton fibers in the second layer as the sheath producing a yarn called SMA core-sheath friction yarn (SMA CSFY). During spinning, the core-sheath ratio and spinning drum speeds were varied. The main purposes of the study were to evaluate the SMA CSFY single yarn tensile strength and its actuating performance against changes in the spinningprocess parameters. The results showed that SMA CSFY with the highest spinning drumspeed and 60% core gave the highest tensile strength and fastest actuation performance.
Badania dotyczyły opracowania przędz rdzeniowych z udziałem składnika posiadającego pamięć kształtu. Druty z pamięcią kształtu zostały zastosowane jako elementy elektrycznie przewodzące. Do produkcji tych przędz zastosowano przędzarkę DREF 3000. Przędze przewodzące były produkowane z rdzeniem z drutów o pamięci kształtu oraz otoczką z włókien bawełnianych (100%). Przędzenie przeprowadzano przy zmianie prędkości bębna przędącego. Głównym celem badań była ocena właściwości wytrzymałościowych otrzymanej przędzy oraz wpływ parametrów przędzenia na pamięć kształtu przędzy. Wyniki badań wskazują, że przędze otrzymane przy najwyższych prędkościach bębna przędącego i udziale rdzenia 60% posiadają najlepsze właściwości wytrzymałościowe i korzystne reakcje na zmianę kształtu.

Opis:
Tetranychus urticae (Acari: Tetranychidae) infesting many plants but Mentha viridis L., and Mentha piperita L., were low in number of infestation. Therefore the objective of this study was to identify the resistance of M. viridis and M. piperita plants against T. urticae by studying the external shape and internal contents of those plants. For morphological studies, dried leaves were covered with gold utilizing an Edwards Scan coat six sputter-coater. For histological studies, arrangements of Soft Tissue technique were used. For phytochemical studies, the plants were cut, dried and then high performance liquid chromatography (HPLC) was used. While feeding the mites were collected from the area between oily glands, trichomes and respiratory stomata in both mint species. The most important leaf structures in aromatic plants are the oily glands found on the external part of the leaves (both upper and lower epidermis). The number of oil glands in M. viridis leaves was greater than in M. piperita; the trichomes on the epidermis of M. viridis were greater in number than in M. piperita; the spongy mesophyll in M. viridis was much thicker than in M. piperita. The essential oils in the leaves of both mint species contained 71 compounds representing 99.61% of the total oil constituents identified from M. viridis before infestation, and 90.95% after infestation, and about 99.65% from M. piperita before infestation, and 99.98% after infestation.

Opis:
The proportional-integral-derivative (PID) controllers have experienced series of structural modifications and improvements. Example of such modifications are set-point weighting and fractional ordering. While the former is to achieve two-degree-of-freedom (2DOF) ability of set-point tracking and disturbance rejection, the latter is to ensure smooth control action. Therefore, this paper reviews various forms of PID controllers and provides a comparative analysis of 2DOF PID and 2DOF fractional order PID (FOPID) controllers. The paper also discusses the conversion of one PID form to another. For the comparative analysis of the various controllers, a class of unstable systems are considered. Simulation result shows that in most cases the conversion from one form to another does not significantly affect the performance of the system. It is also observed that the 2DOF controllers (2DOF PID and 2DOF FOPID) improved significantly the performance of the ordinary PID controllers.

Opis:
El-Hudi gold deposit, located in the South Eastern Desert of Egypt, represent large vein- type gold occurrence. The representative sample revealed the abundance of quartz as main constituent with minor amounts of mineral impurities. Gold was detectable (12 g/t) as determined using atomic absorption. The petrographic study revealed that the gold grains ranged from 10-40 μm. The grain boundaries of quartz are highly stained with iron minerals as hematite and limonite. Sericite mineral is common in discrete gold-bearing veins. Eroded pyrite was detected with high alteration leaving only cubic-shaped cavities behind. Different techniques for gravity separation were used to separate gold from the quartz mineral. After crushing and grinding of the sample, shaking table was used to upgrade the coarser fractions while Falcon concentrator was employed to upgrade the fine fraction. The best concentrate was obtained through grinding the whole sample to less than 0.2 mm, followed by cleaning steps. The gold content is increased from 12 to 145 g/t with total recovery of 78%.

Background: This study aims to examine the predictive effect of perceived organizational politics on employees’ job satisfaction, and the role of personality (extraversion, openness, agreeableness and conscientiousness) in moderating the relationship. Methods: Data were collected using self-report questionnaires from 210 employees working in private organizations in Malaysia. The hypothesized relationships were tested using hierarchical regression analyses. Results: Consistent with the prediction, results of the study indicated that perceived organizational politics was negatively related to job satisfaction (R2 = 0.09). From the four personality traits, only extraversion and openness were found to moderate the relationship between perceived organizational politics and job satisfaction. Conclusion: The findings of this research extent the current knowledge on the importance of personality traits in relation to perceived organizational politics and job satisfaction among employees.
Wstęp: Praca ma na celu przeanalizowanie przewidywanego wpływu postrzeganej polityki organizacyjnej na zadowolenie z pracy pracowników oraz rolę osobowości (ekstrawersja, otwartość, ugodowość oraz sumienność) w kształtowaniu powiązań i wzajemnych stosunków. Metody: Dane zostały zebrane poprzez przeprowadzenie wywiadu ankietowego wśród 210 pracowników prywatnych przedsiębiorstw w Malezji. Hipotezy zdefiniowane na tej podstawie zostały poddane ocenie przy użyciu analizy regresji hierarchicznej. Wyniki: Zgodnie z przewidywaniami, wyniki badania wskazują, że postrzegana polityka organizacji jest odwrotnie skorelowana z zadowoleniem z pracy (R2 = 0.09). Spośród czterech ocenianych cech osobowości, tylko ekstrawersja i otwartość, miały wpływ na zależności pomiędzy postrzeganą polityką organizacji a zadowoleniem z pracy. Wnioski: Otrzymane rezultaty badań poszerzają dostępną wiedzę dotyczącą istotności cech charakteru w relacji z postrzeganą polityką organizacji a zadowoleniem z pracy wśród pracowników.

Opis:
Azo dye is widely used in the textile industry since it is cost effective and simple to use. However, it becomes a continuous source of environmental pollution due to its carcinogenicity and toxicity. Various methods had been used to remove the azo dye in solution. One of the famous and frequently used is the Fenton process. The Fenton process is one of the advanced oxidation processes where iron catalysed hydrogen peroxide to generate hydroxyl radical. Treating azo dyes in solution requires a catalyst to enhance the process of degradation. Herein, high entropy alloys (HEAs) have been proposed as a catalytic material to enhance the performance of Fenton process for azo dye degradation. HEAs have been reported as a promising catalyst due to its high surface area. The higher the number of active sites, the higher the rate of azo dye degradation as more active sites are available for adsorption of azo dyes. The results have shown that HEAs can be used as a catalyst to fasten the Fenton reaction since the degradation time is proven to be shorter in the presence of HEAs. The method derived from the result of this study will contribute in treating azo dyes for wastewater management in the Fenton process.

Opis:
In this study, high performance magnesium-yttria nanocomposite’s room temperature, strength and ductility were significantly enhanced by the dispersion of nano-sized nickel particles using powder blending and a microwave sintering process. The strengthening effect of the dispersed nano-sized nickel particles was consistent up to 100°C and then it gradually diminished with further increases in the test temperature. The ductility of the magnesium-yttria nanocomposite remained unaffected by the dispersed nano-sized nickel particles up to 100°C. Impressively, it was enhanced at 150°C and above, leading to the possibility of the near net shape fabrication of the nanocomposite at a significantly low temperature.

Opis:
The investigation of surface modification of Egyptian calcium carbonate via polymers was achieved with simultaneous ultra-fine grinding. Attrition mill and planetary mill were used for wet and dry grinding, respectively. The parameters affecting the grinding were studied such as ball number, speed and grinding time. The rheological characteristics of the aqueous calcium carbonate suspensions were studied in the presence of different types of polymers. The results indicated that the mechanical force could clearly affect the modification characteristics of calcium carbonate due to its mechanochemical effects. The viscosity of calcium carbonate suspension depends on the volume percentage or weight percentage. The dispersing agent increases the solid concentration for a given particle fineness.

ObjectivesThe aim of this study was to assess the impact of smoking on the whole salivary flow rate (SFR), IgA levels and clinical oral dryness (COD) among active and passive smokers.Material and MethodsThe participants were categorized as active smokers (N = 54) or passive smokers (N = 163). Saliva was collected in tubes and placed in ice storage at –70°C. Salivary IgA levels were assessed in duplication using the enzyme linked immunosorbent assay (ELISA) method. Following the saliva sample collection, the subjects were assessed for COD using the COD score, SFR and caries. Chi-square test, the t-test and ANOVA were employed to compare the clinical impact of the smoking status associated with specific variables (smoking status, number of cigarettes, active caries, gender, age, COD score, IgA level and SFR). A p-value of <0.05 was considered significant.ResultsTwo hundred and seventeen subjects with the mean age of 32.86±6.30 years, with 145 males (66.8%) and 72 females (33.2%), were included in the study. Among the active smokers, 88.8% were males compared to 11.2% females. The active smokers had the mean age of 32.52 years, a COD score of 1.43, an IgA level of 1.39 g/l, and a SFR of 0.37 ml/min. Among the passive smokers, 59.5% were males and 40.5% were females, with the mean age of 32.97 years, a COD score of 0.87 g/l, an IgA level of 1.47, and a SFR of 0.42 ml/min. Active caries showed a positive correlation with the number of cigarettes, with significance in the >35 years age group (p < 0.05).ConclusionsThe study demonstrated significant differences in SFR, IgA and COD scores among the active and passive smokers. The number of cigarettes had a negative impact on saliva production, IgA levels, the oral health status, and the progression of caries with respect to age and gender. Smoking potentially leads to xerostomia associated with active caries.

Powder of $BaCe_{0.54}Zr_{0.36}Y_{0.1}O_{2.95}$ (BCZY) ceramics compound was synthesized by a modified sol-gel method using triethylenetetraamine, TETA as a chelating agent. The samples were dried and calcined at 325°C and 1100°C, respectively. The resulting powder properties were characterized using Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM), X-Ray Fluorescence Spectroscopy (XRF) and Energy Dispersive X-Ray (EDX). At calcination temperature of 1100°C, the sample shows particles with high purity, spherical shape and a single particle size distribution in the range of 342-396 nm. XRF and EDX analysis revealed that the elemental composition of Ba, Ce, Zr and Y present in the sample is almost the same as the nominal stoichiometric composition of BCZY compound. Thus, TETA is one of the potential chelating agents that can be used to synthesize high purity and homogeneous spherically grained cerate-zirconate powders.

Opis:
Species distribution models are used to predict ideal grounds, species range, and spatial shifts in an ecology over a span of time. With an aim to use Maximum entropy model (MaxEnt), presence records and pseudo-absence points are used to predict the Tachypleus gigas spawning activity for 2030 and 2050 in northeast India. The bearings of sixty T. gigas spawning grounds identified in 2018 were inserted into ArcGIS v.10.1. Meanwhile, 19 environment variables were inserted into MaxEnt v. 3.3.3, before the model performance was tested using receiver operational characteristics and area under curve (AUC). With an AUC of 0.978,85% was achieved for isothermality (bio3) and 74% for temperature (x̄= average) of the wettest quarter (bio8), all of which were inserted into ArcGIS to produce spatial maps. Although we learnt that T. gigas are still spawning in Odisha in 2030 and 2050, their distribution range is predicted to shrink due to the coastal morphology change. The climate conditions in Odisha revolve with the monsoon, summer and winter seasons from which, temperature variations do not only influence the annual absence/presence of spawning adults but also, the survival of juveniles in natal beaches. The use of MaxEnt offers novelty to predict population sustainability of arthropods characterized by oviparous spawning (horseshoe crabs, turtles, terrapins and crocodiles) through which, the government of India can take advantage of the present data to initiate the coastal rehabilitation measures to preserve their spawning grounds.
