ADSORPSI LOGAM BERAT SENG (Zn) DENGAN MENGGUNAKAN AKAR RAMBUT Solanum nigrum L GALUR A4 KERING TERIMOBILISASI DALAM Na-alginat
No full textABSTRACTRoot tissue of Solanum nigrum L A4 strain was found to adsorb heavy metal especially Zinc (Zn). Compared with activated carbon used as adsorbent on industrial waste water treatment process, the adsorption by root tissue of Solanum nigrum L was higher. The adsorption of Solanum nigrum L was represented by Langmuir and Freundlich isotherms equation. Ground powder of Solanum nigrum L was immobilized by natrium alginate for a practical use. Zinc concentration adsorbed by immobilized Solanum nigrum L were higher than ground powder form. The adsorption capacity shows the capacity of the adsorbent used. It was calculated through dividing adsorbat (mg) with the weight of the adsorbent (gr). Even the concentration of zinc adsorbed by immobilized beads was higher, the adsorption capacity of ground powder form of Solanum nigrum L was higher then immobilized beads. It might be caused by the natrium alginate which also adsorbed zinc and formed higher weight of adsorbent, and implies that polymer used for immobilization creates a binding coated on the Solanum nigrum L ground powder surface.Key words : adsorption, plant tissue, zinc, immobilizatio

The exercises used are medicine ball side throw and kettlebell side swing. This exercise has advantages and disadvantages of each. The purpose of this study was to determine the effect of medicine ball side throw and kettlebell side swing exercises on increasing the speed of hit results for athletes in field hockey. This study uses an experimental method with the 1st independent variable is the practice of medicine ball side throw and the second independent variable is the kettlebell side swing. The dependent variable is an increase in the speed of a hit. The instrument used in this study was a hit test and was calculated using a speed radar gun. The sample used in this study was the Kijang Hockey Club athlete who had played at the PORDA, PON or SEAGAMES level using a purposive sampling technique. Based on data processing and data analysis, the authors conclude that the exercise to increase power with medicine ball side throw and side swing kettlebell both have an influence on increasing the speed of the hit hit for athletes. The author gives suggestions for further research on strength training using a variety of other exercises to improve a technique, according to which the researchers have tried to know the effect on increasing the speed of the hit results in a field hokey sport
From the river to the sea? : honour, identity and politics in historical and contemporary Palestinian rejectionism
No full textThe present thesis seeks to understand and explain the rhetoric and
behaviour of the rejectionist 'current' within the Palestinian national
movement. It proceeds from the view that extant scholarship, primarily from
within the fields of terrorism and security studies, has profoundly
misunderstood rejectionist speech and behaviour by ignoring the
explanatory capacity of Emic - the research subject's perception - as well as
the influence of the sociocultural milieu within which rejectionism exists.
The thesis proceeds to set up a 'socioculturally sensitive' analytical
framework drawn from social identity theory, a heuristic, non-reductionist
model for understanding group interaction and conflict. Emphasizing
cultural norms and cues identified by anthropologists as salient in the
eastern Mediterranean, the thesis suggests that the social value of honour,
patron-client dynamics and a firmly entrenched group orientation must be
significant elements of a model for understanding rejectionist behaviour.
The main analytical narrative suggests that for reasons derived from
ideology, patron-client relations and group dynamics, what has distinguished
the rejectionists from the mainstream have been a qualitatively different set
of preconditions for, and objectives of diplomatic negotiations. To the main
rejectionist factions the goal of liberating Palestine has always been
inextricably intertwined with the goal of restoring national honour; one
without the other has been impossible and to claim otherwise would mean a
depletion of factional and personal honour. To the rejectionists, there has
never been any question of deviating from the fundamental goals - national
recognition, repatriation, self-determination and independent statehood, not
even for tactical reasons. This 'higher standard' likely derives from their
structurally and politically subordinate position within the national
movement, and the need to creatively enhance their own social status and
appeal
Reliable materials performance data from impact testing
No full textSwinburne University of Technology has a wide range of facilities for measuring the mechanical properties of materials under impact and high speed loads. The facilities include a drop‐weight test machine, three sets of split Hopkinson pressure bar (SHPB), a gas gun and an INSTRON test machine, which are capable of conducting experiments in the strain rate range of 10-3 to 103 s-1. It is difficult to conduct reliable experiments in the strain rate range of 102 to 103 s-1, which is vital, for instance, to the development of crash‐worthy vehicles and the high-speed machining of aerospace metals. The SHPB has been commonly used for the dynamic characterisation of materials for over a century. The high strain rate testing capabilities and simplicity of the technique are reasons for its popularity. This technique can be used for the dynamic characterisation of various materials such as brittle, ductile and soft materials. This technique can also be applied in several load directions such as compression, tension, torsion, shearing and triaxial tests. It also can be used for conducting impact bending to determine the dynamic fracture toughness of materials. Despite its longevity, the Hopkinson bar technique has not been standardised yet. The standardised SHPB technique is necessary in order to provide guidelines for determining the intrinsic material properties. This thesis fills a gap covering materials that has not been discussed yet in previous researches. This research examines the reliability of the compressive SHPB on the metal testing by experimental work, in parallel with the numerical simulation. The main outcomes of this thesis include the quality of bar production, standardisation of the pressure bar, specimen design criteria, consistency of the testing results, identification of measurement uncertainties, effect of paper layer as pulse shaper, and detailed data processing and analysis. It was found that if a greater care and preparation of apparatus and the specimen were taken, and then followed by a standardised data processing and analysis, the SHPB technique produced quite consistent results (within an acceptable error of less than 5%). This consistency was confirmed by the apparatus itself (repeated test) and inter-equipment (compared with the quasistatic and round-robin tests). Based on those results, the author believes that the SHPB technique could and should be standardised in the future
