Industries such as agriculture and food have used polypropylene bag widely used as it is cheap and easy to find. Fertilizers industry especially needed to use the polypropylene bag that have high protection barrier against the high-level humidity especially we living in Malaysia that have high humidity in the air. By layering the polypropylene bag with another polypropylene bag, the moisture problem can be overcome. The polypropylene bag for fertilizers consists of 2 layers which is the woven polypropylene bag and the clear polypropylene bag. However, when assembling this two-polypropylene bag, worker needed to manually insert the clear polypropylene bag into the woven bag. This increases the time process in production, high labour force needed and also higher cost for mass production. Furthermore, repetitive works can cause strain to the worker and increases the number of errors. To overcome this issue, the automated polypropylene bag assembly system is proposed. For this paper, we only focus on the lifting method of the automated polypropylene bag assembly system. With the used of the automated polypropylene bag assembly system, the repetitive works and labour force can be reduced. This will also give out cleaner and consistent last product.

Important drawbacks of Coriolis experimental setup and devices are their multiple parts and cost to own. Simplicity, traceability, and measurability are the major concern. This paper presents a preliminary design process of Coriolis acceleration experimental device to visualize the effect of Coriolis and enable the calculation of acceleration components to facilitate students for a better understanding of this phenomenon. This is realized through a slidable collar with a marker and accelerometer attached on it and a rotating rod that shows a visible yet erasable mark from the marker’s path. The design process went through typical engineering design processes such as morphological study, functional decomposition, and Pugh chart. Next, Finite Element Analyses (FEA) were performed to determine the mode shapes, followed by analytical calculation of the dynamic reaction experienced by motor. In addition, this kit provides opportunity for students to manually calculate the actual acceleration component based on theory learnt which is considered innovative. The use of controllable motor for rotating the rod could vary the travelling path of the marker, subsequently diversify the problems for student to solve.

In this study, the properties of PALF/PET electrospun mats were studied. Different ratio of PALF/PET were electrospin to determine the optimum parameters for fabricating electrospun PALF/PET with minimum defect. The sample obtained were then characterized for its morphology and chemical properties. FTIR studies were done to understand the interaction occurred between PALF and PET with increasing PALF ratio. From the FTIR result, increasing PALF showed similarities spectra with raw PALF peak at 1100cm-1 indicating the influence of PALF in the fibers. This peak did not appear at low PALF content. The obtaining electrospun mats were observed under FESEM to characterize their morphological properties. Increasing in PALF ratio also attributes to the decreasing of size diameter and diameter range. From the result, PALFPET4 shows the smoother morphology with linear properties and smaller average size diameter.

The improvement of elite building items produced using regular assets is expanding around the world due to renewable and ecological issues. Among the wide range of characteristic assets, kenaf plants have been broadly abused in the course of recent years. The aim of this research is to develop long kenaf composites and long kenaf with woven glass reinforced polyester resin composites. Tensile test helps to determine how the material will react to forces being applied in tension. The test that was conducted included Post Impact Tensile test and Single Edge Notch Bend. Tensile test determines strain-stress while single edge notch bend determines the fracture of the specimen. The experiment was conducted using Universal Testing Machine (UTM) to find the mechanical properties. The experiment considered ASTM D3039 for tensile test and ASTM D5045 for single edge notch bending. From there, the damage area of the composites could be predicted. Meanwhile, it showed the best configuration for the newly developed material in impact test. So, these hybrid composites are viable to be extended into a newly developed material for further investigation.

Electrospinning process involved strong deformations of polymer fluid at rapid fibrous structure formation within mili seconds by several influence from the distinctive spinning parameters. This study has been conducted to achieve a desirable flow rate and optimum tip-to-collector needle distance for the electrospinning of polycaprolactone (PCL). For this aim, the morphological structure of fibre spun from 10 wt% PCL solution dissolved in dichloromethane (DCM) at 0.05 – 0.20 ml/min flow rate and 10 – 15 cm tip-to-collector needle range were characterized by FESEM. The results obtained show that average diameter of electrospun PCL fibres decreases with increasing flow rate at any needle to collector distance. In addition, the tip-to-collector needle range at 15 cm produced more beads-on-string fibres compared to 10 cm distance. The fibre thickness is reduced as both of the flow and the distance of needle tip-to-collector increased. All of the obtained electrospun PCL fibres are in non-uniform, long, porous beaded fibrous structure for all flow rate and needle distance tip-to-collector values.

The development of humanoid robot shows great significant in domestic, services and medical application. Humanoid robot is developed to aid human daily task. However, the appearances of the humanoid robot affect the robot’s functionality as well as the acceptance of its usage in public. Hence, this study focuses on developing a new torso structure design for a humanoid robot for better performance. The new humanoid robot torso design is based on the actual human-like proportion and human torso structure. A 3D model of the torso has been designed and simulated in SolidWorks software. Aluminium is used as the raw material for the humanoid robot torso. The humanoid robot parts are fabricated via Computer Numerical Control (CNC) Machining and Water Jet Cutting. The design was then analyzed using Finite Element Analysis (FEA). Simulation results show that the new humanoid robot torso structure design is more stable and stronger where the maximum displacement for initial torso design is 9.715e-002 mm while after improvement is 6.783e-003 mm. The proposed system with 1 DOFs shows high strength and easy-to-control features and it is also proven that the simplified design is the best option to increase strength and stability.

This paper addresses the effects of plate thickness and defect location on guided wave propagation in carbon/epoxy plates. A three-dimensional (3D) finite element model (FEM) of the plate was developed using MATLAB program codes, and simulated in Abaqus/Explicit. Referring to experimental ultrasonic C-scan images, the complex impact damage was modelled with irregular-shaped delamination and through-thickness matrix cracks. The simulated results show that a slower arrival time signal and amplitude drop of guided wave captured behind the defective region can be used as an indicator of the impact damage. A largOer scattering occurred when delamination was located closer to the plate surface. The extent of scattering gets larger, especially in the direction of 345o from the excitation point. It is also observed that the impact damage can still be detected through a line scan method across the impact damage, although the wave attenuation is greater in a thicker composite plate. By investigating these factors independently, the trends of the scattered guided ultrasonic waves can be classified and perhaps will revolutionize a smart non-destructive method for composite structure in the future.

This study examines the potential of artificial neural network (ANN) to predict Total Volatile Organic Compounds (TVOCs) released via decomposition of local food wastes. To mimic the decomposition process, a bioreactor was designed to stimulate the food waste storage condition. The food waste was modeled based on the waste composition from a residential area. A feed forward multilayer back propagation (Levenberg – Marquardt training algorithm) was then developed to predict the TVOCs. The findings indicate that a two-layer artificial neuron network (ANN) with six input variables and these include (outside and inside temperature, pH, moisture content, oxygen level, relative humidity) with a total of eighty eight (88) data are used for the modeling purpose. The network with the highest regression coefficient (R) is 0.9967 and the lowest Mean Square Error (MSE) is 0.00012 (nearest to the value of zero) has been selected as the Optimum ANN model. The findings of this study suggest the most suitable ANN model that befits the research objective is ANN model with one (1) hidden layer with fifteen (15) hidden neurons. Additionally, it is critical to note that the results from the experiment and predicted model are in good agreement.

This study aims to investigate the effect of additives (sulfuric acid and ethanol) in sodium sulfate as photoelectrochemical (PEC) electrolyte on the photoconversion efficiency of tungsten trioxide loaded titania nanotubes (WTNT). Titania nanotubes (TNT) were first fabricated via anodization while the deposition of tungsten trioxide onto the titania nanotubes (WTNT) were successfully carried out via electrodeposition at various potentials. Assessing the PEC performance of WTNT fabricated at pH 1.5 in solely sodium sulfate was not adequate to enhance the PEC performance of WTNT compared to blank TNT. A similar result was obtained when sulfuric acid was added or when fabricating WTNT at pH 0.8. Adding ethanol into sodium sulfate electrolyte has successfully improved the PEC performance of WTNT with observable inclining photoconversion efficiency trend upon increasing electrodeposition potentials of WTNT from −0.45 V to −0.75 V.

The objective of this paper is to develop mathematical relationship between average pore size and porosity of porous polycaprolactone/hydroxyapatite (PCL/HA) composite and investigate the combined effect of temperature and pressure of foaming process and presence of HA. Porous PCL/HA composite was prepared using supercritical carbon dioxide (ScCO2) solid state foaming process. Three different temperatures and pressures of foaming process were varied at 35°C, 40°C, 45°C and 10MPa, 20MPa, 30MPa respectively. Meanwhile weight of HA was varied at 10, 20, 30 and 40 wt%. The result from analysis of variance (ANOVA) using Microsoft Excel found that average pore size is reduced with higher pressure and content of HA presence does not significantly affect the average pore size due to poor distribution of HA. Meanwhile for porosity, higher temperature is more dominant in increasing of porosity compared to the HA content. In addition, both designed models have low values of Average Absolute Relative Deviation (%AARD) and high value of coefficient of determination (R2) which reflects a good and satisfying result between the experimental values and model predicted values.

The amount of plastic waste in India is reaching a gigantic scale. Wastes from household, industries and medical facilities contribute towards this. As the plastic waste is a cause of various environmental and health hazards, its proper management that leads to an effective reuse or disposal is a concern for the Government and civic bodies. Waste plastic, when added to hot aggregates, forms a fine coat of plastic over the aggregates and such aggregates, when mixed with the binder is found to give a mix that has higher strength and resistance towards the deteriorative actions of water. Thus, (the bituminous Roads using waste plastic in the wearing course) also called as plastic roads are now gaining popularity in India. With the Indian Road Congress bringing out a code of specifications on plastic roads (IRC SP: 98 -2013), many agencies are coming forward to implement plastic roads in India as it is a sustainable method and also need of the hour. However, for a large scale implementation, the performance and longevity of these roads need to be evaluated comprehensively. This paper presents the various properties of bituminous mix with 8% waste plastic when compared with normal bituminous mix with the help of a comparative case study. In Pune, Maharashtra, India ten city roads which were overlaid with normal bituminous mix and ten roads which were overlaid by bitumen mixed with shredded waste plastic were studied for their performance over duration of two years from the time of laying of the overlays. Laboratory experiments and on- field tests were carried out to evaluate their functional and performance characteristics after they were opened to traffic. The results report an improved performance of plastic roads over the conventional ones.

Samples were collected and phytopathological analysis of potato tubers during harvest was conducted according to conventional methods. Identification of pathogens of fungal diseases was carried out at the Institute of Plant Protection of the National Academy of Sciences of Ukraine, according to conventional methods.

Results. The performance of potato varieties in the application of a set of protection measures in FG “Gabenets” was evaluated. It was analyzed that the yields of varieties on the production crops of the farm were quite high and ranged from 50.25 to 58.10 t / ha, and the yield from one bush — from 1.014 kg to 1.163 kg. The highest yield was on production crops of the Pirol variety and amounted to 58.10 t / ha, compared to the control — 47.30 t / ha. Phytopathological analysis of potato chips varieties was carried out, which resulted in the detection of dry fusarium potato rot in control variants of Opal, Karlenа, Fantasia and Kibitz. No crop disease was detected in production crops where a system of protective measures was applied. Pirol cultivar has proven to be resistant to fungal pathogens.

Conclusions. Protective measures during the vegetation of potato plants prevented the mass development of fungal diseases on potato tubers, which in turn will have a positive effect on the stickiness of the tubers and preserve their marketability.

This study employed a Cobb-Douglas stochastic production frontier function to estimate the level of technical efficiency. The results of the analysis showed that cropping season of mango growers have been round year. Difference of the study compared to past researches related to tropical fruits analyzed efficiency of three seasons instead of only focusing on efficiecy of one seasson or total a year. The findings revealed that season 3 ranked first in terms of technical efficiency (58.2%), follwed by season 1 (53.6%) and then season 2 (49.2%). Moreover, the input variables that explained technical efficiency were were fertilizer (root), fertilizer (leaf) and labor in season 1; pesticide, fertilizer (leaf) and labor in seaon 2; and pesticide, fertilizer (root), fertilizer (leaf) and labor in in season 3. In addition, major determinants of socioeconomic characteristics influenced positively on technical efficiency were were plant density and land area in season 1 and season 3; market access, plant density and land area in season 2. Likewise, the constraints to mango production were wrapping bag and classifying sale in season 2, and age and wrapping bag in season 3.

Die Goethe-Universität zieht um. Staatliche Raumproduktion und die Neoliberalisierung der Universität
Authors: Belina Bernd , Petzold Tino , Schardt Jürgen , Schipper Sebastian
Published: November 2019

Im Zuge des Bildungsstreiks 2009 besetzten Studierende der Johann Wolfgang Goethe-Universität (JWGU) in Frankfurt das „Casino“, ein zentrales Gebäude auf dem neuen IG-Farben-Campus im Westend. Während frühere Besetzungen von Universitätsgebäuden auf dem alten Campus in Bockenheim von der Universitätsleitung zwar auch nicht gerade begrüßt, aber doch toleriert worden sind, ließ das Präsidium im jüngsten Fall 176 Studierende nach nur drei Tagen polizeilich räumen. Um diesen repressiven Wandel im Umgang mit studentischem Protest zu verstehen, rekonstruieren wir im Folgenden die Art und Weise, wie die JWGU als Teil des Staatsapparates Universität zu unterschiedlichen Zeiten zwei Campus als konkrete Orte (places) hervorgebracht hat, die jeweils als Ausdruck und Verdichtung der nationalen und lokalen gesellschaftlichen Kräfteverhältnisse im Fordismus bzw. Neoliberalismus zu interpretieren sind.
Polizieren als (post-)koloniale Praxis. Ein Beitrag zur Debatte um kritische Polizeiforschung
Authors: Müller Markus-Michael
Published: November 2019

Der Beitrag plädiert für eine Integration postkolonialer Theorieansätze in eine kritische Polizeiforschung. Es wird argumentiert, dass diese das kritische Potenzial dieser Forschung dahingehend erweitern können, dass sie etablierte, aber inhärent eurozentristiche Narrationen bezüglich der Entstehung, Entwicklung und Funktion der Polizei als eine genuin westlich-national situierte Institution infrage stellen. Eine daraus abzuleitende Anforderung besteht darin, nicht nur die Relevanz postkolonialer Ansätze und Arbeiten anzuerkennen, sondern auch bereit zu sein, von postkolonialen Erfahrungen für die hiesige Forschungspraxis zu lernen.
Neue Horizonte feministischer Wissensproduktion
Authors: Schuster Nina
Published: November 2019

In feministischen Diskussionen wird seit den Anfängen der Zweiten Frauenbewegung Ende der 1960er Jahre das Verhältnis von wissenschaftlicher und bewegungsbezogener Wissensproduktion als ein Verhältnis von ‚Theorie und Praxis‘ diskutiert. Dabei geht es idealerweise auch um eine Anerkennung der unterschiedlichen ‚Qualitäten‘ der verschiedenartigen Wissensformen und -praktiken (handwerkliche, soziale, theoretische, erfahrungsbezogene, künstlerische), verbunden mit dem Versuch, deren Bewertung neu auszutarieren und ihre Hierarchisierung herauszufordern. Dies impliziert, die Unterschiedlichkeit sozialer Positionierungen in ihrem sozialen, politischen und ökonomischen Kontext zu reflektieren.

Intersektionalität privilegierter Identitätsdimensionen
Authors: Meier Lars
Published: November 2019

Privilegierte männliche, hochmobile Finanzmanager sind nicht nur Teil abstrakter ortsübergreifender Netzwerke, sondern sie arbeiten an konkreten Arbeitsorten. Am Beispiel deutscher Finanzmanager in London und Singapur arbeite ich die Relevanz des lokalen Arbeitsortes für die Identitätsaufführungen der globalen Elite mit einer intersektionalen Perspektive heraus. Da die Performanz dieser Identitätsdimension als dynamischer Prozess verstanden wird – also als eine Dynamik, in der diese im Handeln alltäglich erzeugt und aufgeführt wird – werden die alltäglichen Aufführungen der Globalen Elite in ihrer Beziehung zu dem Arbeitsort, an dem die Aufführungen stattfinden, analysiert. Es wird deutlich, dass mit dem Ansatz der Intersektionalität auch privilegierte Identitätsdimensionen in den Blick genommen werden können. In Abhängigkeit vom Ort der Performanz differenziert sich die Identitätsdimension globale Elite und überschneidet sich in spezifischer Weise mit der Identitätsdimension des Weißseins.
Stadt- und Elitesoziologie – Desinteresse oder Kooperation?
Authors: Hartmann Michael
Published: November 2019

Elite- und Stadtsoziologie zeichnen sich bislang dadurch aus, dass sie die Ergebnisse der jeweils anderen Disziplin weitgehend ignorieren. Dabei gibt es gerade in Hinblick auf die Debatte über die rasant gestiegenen Immobilienpreise in den Metropolen interessante und fruchtbare Verknüpfungsmöglichkeiten.
Mit Rechten reden, zu Rechten forschen? Ein Widerspruch auf Einladung
Authors: Ammicht Quinn Regina
Published: November 2019

Der Text ist eine Antwort auf Robert Feustels „Mit Rechten reden, zu Rechten forschen?“. Er nimmt die beiden irritierenden Titelfragen als Irritation auf und stellt sie in den Kontext des Selbstverständnisses von Wissenschaft und des Verständnisses von „Realität“. Daran schließen sich zwei Vorschläge aus dem Bereich anwendungsbezogener Ethik an: Die Zuschreibung singulärer Identitäten als Gewalt zu verstehen und diese das Unterlassen dieser Zuschreibung für empirische qualitative Forschung als wissenschaftlichen und ethischen Imperativ zu setzen.
