    The Fiber Reinforced Polymer Composite (FRPC) has been widely employed in structural applications. However, adding nanoparticles such as multi-walled carbon nanotubes (MWCNTs) can be used to improve the composites' mechanical properties substantially. The purpose of this study is to investigate the stability of MWCNTs in distilled water (DW) and dimethylformamide (DMF). Electrophoretic deposition (EPD) was chosen as the method for depositing MWCNTs onto carbon fiber (CF) fabric because of the advantages of simple equipment and inexpensive cost. Thus, the effect of voltage and deposition time were examined to attain the ideal condition for the EPD of MWCNTs onto CF fabric. The stability of dispersed MWCNTs in various dispersing mediums was explored as the importance of the MWCNTs to remain stable in the medium is essential to achieve homogeneous deposition. The UV-Vis and colloidal stability test revealed that MWCNTs dispersed in DMF have greater stability than DW. Scanning Electrode Microscopy (SEM) images exhibited that 10 minutes and a 20 V voltage were the optimal conditions for the deposition of MWCNTs onto CF fabric.   &nbsp

    Some factors which cause criminal act in falsifying land certificates are as follows: the implementation of incorrect law, non-transparent legal enforcement, frail administrative system, the ignorance of the personnel of the National Land Board, people's lack of knowledge in law, judges' negligence in the hearing facts and evidence, the involvement of the military personnel in falsifying the certificates, and sanction stipulated in UUPA (Agrarian Law) is too lenient. Government Regulation No. 24/1997 on Land Registration and Article 52 of UUPA on criminal sanction state that perpetrators in land crime, as it is regulated in Article 19 of UUPA, is sentenced to 3 months and fined Rp 10.000, Law Enforcement for perpetrators who have falsified land certificates is regulated in Articles 263 to 266 of the penal code on criminal act of falsifying certificates and Articel 52 of UUPA on criminal sanction on Land Crime. in order to forestall, handle, and settle the conflict on land, old feudalistic, centralistic bureaucratic, authoritative, and repressive paradigm should be changed to populist, democratic, and decentralized paradigm and respect for human rights

    Meet their needs, consumers are faced with various types of products offered by businesses. With the various types of products and freedom for consumers to choose a variety of products offered lead to competition among businesses. Competition among businesses to market products that offer the consumer interest can be done in various ways, one of them promoting products through print media advertisements. Advertising is a tool for businesses to introduce their products to the public in order to influence the tendency for people to use or consume. The problem is, the ad does not always give a true or deceptive information about an advertised product, so that consumers can be harmed by the behavior. If perpetrators of this background can be formulated several problems, namely how the forms of advertising fraud that harm consumers, whether fraud ad meets the elements of a crime, how to determine the criminal liability for those who make advertising the sale of goods that harm consumers in Indonesia based on the Code of Criminal Law and Law 8 of 1999 on Consumer Protection

    Observations from Space: A Unique Vantage Point for the Study of the Environment and Possible Associations with Disease Occurrence

    Get PDF
    Health providers/researchers need environmental data to study and understand the geographic, environmental, and meteorological differences in disease. Satellite remote sensing of the environment offers a unique vantage point that can fill in the gaps of environmental, spatial, and temporal data for tracking disease. The field of geospatial health remains in its infancy, and this program will demonstrate the need for collaborations between multi-disciplinary research groups to develop the full potential. NASA will discuss the Public Health Projects developed to work with Grantees and the CDC while providing them with information on opportunities for future collaborations with NASA for future research

    Asas Ultimum Remedium (the Last Resort Principle) Terhadap Anak Yang Berkonflik Dengan Hukum Dalam Rangka Perlindungan Anak (Studi Putusan Mahkamah Agung Republik Indonesia Nomor 125/pid/a/2012/pn.gs)

    The philosophy of juvenile justice system is to emphasize the rehabilitation of children in conflict with law as a person who has restrictions compared with adults. Children need the protection of the state and the society in the next period. It is necessary to seek a minimum intervention of the juvenile justice system against the children in conflict with law as a good strategy to protect them. The ultimum remedium/the last resort principle aims to protect the children in conflict with law in order to get their brighter future by keeping them away of the formal juvenile justice system and put it as the last choice to solve their cases. The ultimum remedium/the last resort principle is also useful to help the children in conflict with law by giving them warn and chance so that, they can find their identity and be the man in charge for themselves, their family, their society and their country. There will no presecution against the children in conflict with law and also they wont known as convict by applying the ultimum remedium/the last resort principle. It is why the juvenile judges need to really understand the principles of law and regulations relating to the disposal of the child so as to produce a wise judgment for the children in conflict with law

    Characterisation of cassava biopolymers and the determination of their optimum processing temperatures

    This work reports the characterisation of cassava biopolymers. Moreover, the effects of processing temperature on the tensile properties and phase morphology of cassava biopolymers were investigated. Eight diff erent temperatures were selected as processing temperatures in sample preparation of the cassava biopolymers. Variance analysis justifies that 165 and 170°C are the optimum processing temperatures in producing maximum tensile properties. The present study reveals that the range of processing temperatures for cassava biopolymer was relatively lower as compared to the majority of the petroleum-based polymer. However, its low processing temperature makes this biopolymer has enormous potential in the development of fully biodegradable composites

    The study aimed to identify the strategic sensitivity and its impact on enhancing the creative behavior of Palestinian NGOs in Gaza Strip, and the study used the descriptive analytical approach and the questionnaire as a main tool for collecting data from employees of associations working in Gaza Strip governorates, and the cluster sample method was used and the sample size reached (343) individuals (298) questionnaires were retrieved, and the following results were reached: The relative weight of strategic sensitivity was 79.22 (%), and the relative weight of creative behavior was 78.99 (%), a statistically significant relationship between all strategic sensitivity and creative behavior, and the presence of a sensitivity effect The strategy’s strategy on creative behavior, there are statistically significant differences in the scale dimensions attributable to the gender variable and the differences were in favor of females, there are no statistically significant differences between the averages of strategic sensitivity due to the age variable, and the educational qualification, and there were no statistically significant differences in creative behavior according to The gender variable, age, educational qualification, specialization, and the study presented a set of recommendations, the most important of which are: the need for civil organizations in Gaza Strip to seek funding from external countries in order to provide self-income for associations to face crises and give them independence Mechanism in order to keep them to carry out their role in society, the need to follow up the strategic plan of civil organizations using e-mails as they pave the way to reach excellence and creativity in the field of work
