We investigate the mass-radius relation of neutron star (NS) with hyperons inside its core by using the Eddington-inspired Born-Infeld (EiBI) theory of gravity. The equation of state of the star is calculated by using the relativistic mean field model under which the standard SU(6) prescription and hyperons potential depths are used to determine the hyperon coupling constants. We found that, for 4×10 6 m 2 κ 6×10 6 m 2 , the corresponding NS mass and radius predicted by the EiBI theory of gravity is compatible with observational constraints of maximum NS mass and radius. The corresponding κ value is also compatible with the κ range predicted by the astrophysical-cosmological constraints. We also found that the parameter κ could control the size and the compactness of a neutron star.

New product development (NPD) is essential for large, as well as small and medium, enterprises (SMEs). Despite its importance for the economy, challenges remain in the NPD in SMEs. Product success is related with the NPD process, so it is important for SMEs to be able to design their NPD process. This paper aims to identify SME’s NPD research topics, the characteristics of the NPD process in SMEs, and important aspects to be considered for NPD process design. The literature review is done with the analysis of 99 selected academic articles from Scopus and ScienceDirect. Content analysis, bibliographic analysis, and clustering method (based on Pearson’s correlation coefficient) are used to conduct the identification. Less-formal processes, informal strategic planning, limited resources, need technology support, and lack of capabilities in certain fields are some of the characteristics of SME’s NPD. Collaborative product development, competitive advantage, information and communication technology (ICT), concurrent engineering, quality function deployment, and continuous improvement are important keywords based on previous research in SME’s NPD. Design activities in NPD, collaboration and source of innovation, and process modelling, tools, and techniques appear to be important aspects related with the SME’s NPD process.

We investigate the flux compactification mechanism in simple toy models of Einstein-Born-Infeld theories. These are the direct generalizations of the Einstein-Maxwell flux compactifications that recently gained fame as a toy model for tunneling in the landscape. Our investigation reveals that the Born-Infeld form does not significantly modify the qualitative result of the Einstein-Maxwell theory. For the case of Einstein-Higgs theory, however, we found that the effect of Born-Infeld nonlinearity is to render all q > 1 extradimensional compactification unstable against semiclassical tunneling to nothing.

This study scrutinize the business strategy at State-Owned Enterprises (SOEs) in Indonesia that is affected by innovation. Formulation and implementation of SOEs business strategies are theoretically and empirically determined by innovation. The purpose of this study was to determine and analyze the effect of innovation on business strategy of SOEs. This study was conducted using a survey method with a quantitative approach. The units of analysis of this study were 64 SOEs that have applied the Criteria for Performance Excellence since 2012. Data were obtained from survey results through questionnaires distributed directly to the representative of SOEs managements. Data were analyzed using descriptive statistical analysis and SEM-PLS. The results in general reveal that innovation has a positive and significant effect on business strategy. The impact of this study may be continued on a discussion of excellent performance.

ABSTRAKPeran sektor pertanian di Indonesia memiliki multi fungsi terkait dengan lingkungan, ketahanan pangan, sosial ekonomi, dan budaya. Strategi utama dalam menjaga multi fungsi pertanian adalah: (a) meningkatkan kesadaran terhadap pertanian dan masyarakat pedesaan; ( b) mendukung kebijakan harga pertanian; ( c) meningkatkan apresiasi terhadap multi fungsi pertanian; (d) meningkatkan upaya konservasi tanah; dan ( e) menentukan langkah penataan lahan sesuai dengan program revitalisasi pertanian. Kendati lahan pertanian memberikan jasa pelayanan lingkungan kepada masyarakat, namun petani tidak memperoleh insentif yang memadai dalam hal jaminan berusahatani, subsidi input, pengawasan kualitas pasokan pertanian, dan dukungan akses pasar. Oleh karena itu, gagasan insentif jasa lingkungan pertanian patut diimplementasikan. Akan tetapi, untuk kelancaran implementasi insentif jasa lingkungan pertanian tersebut perlu dilakukan terlebih dahulu analisis pemangku kepentingan diiringi dengan proyek percontohan. Dengan kata lain, beberapa langkah strategis seperti sosialisasi dan uji coba kegiatan perlu disiapkan. Modifikasi pembayaran jasa lingkungan dapat direkomendasikan dalam implementasi insentif jasa lingkungan pertanian di Indonesia.

The main strategies to maintain the multifunctionality of agriculture are as follows: (a) improving the awareness on the agriculture and rural community; (b) providing the favorable price policy of agriculture; (c) enhancing the appreciation on the multifunctionality of agriculture; (d) improving soil conservation efforts; and (e) delineating the prime agriculture land in accordance with revitalization of agriculture, fisheries, and forestry program. Agricultural land provides environmental services to community; however, farmers deserve incentives such as secure tenure, subsidized inputs, quality control of agricultural supplies, and better market access. Hence, the notion of agri-environmental service incentives is essentially implemented. However, for better implementation, it should be initiated employing stakeholder's analysis through a pilot project activity. In other words, there is a need that a road map strategy is implemented, including its socialization and implementation. Modified mechanism model of payment for environmental services is recommended in implementing agri-environmental service incentives in Indonesia.

Proses pada pabrik biohidrogen dari biomassa terbagi menjadi beberapa unit proses, yaitu unit pengolahan awal bahan baku, unit gasifikasi, unit char combustor, unit kompresi, unit H2S Removal, unit steam reforming, unit water gas shift, dan unit pressure swing adsorber. Pada penelitian ini akan dijelaskan pengendalian pada kompresor dan steam reformer. Kedua unit tersebut penting dikendalikan agar mencapai tekanan yang diinginkan pada masukan H2S Removal dan untuk mendapatkan gas hidrogen pada unit Steam Reformer. Pengendali yang digunakan adalah pengendali PI karena hampir dapat menangani setiap situasi pengendalian proses. Untuk mendapatkan kinerja yang optimum, dilakukan penyetelan pengendali dengan metode Ziegler Nichols, Lopez, dan Default Unisim, kemudian membandingkan nilai IAE dan ISE dari ketiga jenis penyetelan tersebut. Hasilnya pengendalian tekanan dan suhu yang optimum adalah dengan metode penyetelan pengendali Ziegler Nichols. Sedangkan pengendalian surge-01, surge-02, surge-03 pada kompresor metode yang paling optimum adalah Default Unisim, dan untuk surge-04 adalah metode Lopez.

Background: First case of pandemic COVID-19 was diagnosed in December 2019 in China from where it spread throughout the world. In Pakistan, first case was diagnosed in February 2020 which resulted in a complete and several smart national lockdowns. National Command and Operation Center (NCOC) and Ministry of Health published guidelines for patient’s treatments during pandemic which includes: 1) providing only emergency Treatments 2) Patient’s pre-admittance Questioning, 3) Increasing intervals between appointment, 4) prevent crowding in waiting rooms, 5) Wearing masks at all times. 6) Wearing PPE. Methods: Data from all clinical departments of Frontier Medical and Dental College and Hospital Abbottabad was collected between March and December 2020 which included Number of; 1) Patients treated 2) Medical Staff 3) patients with positive COVID-19 reports 4) healthcare workers suffering from COVID-19. And 6) Post treatment Virus Infected patients. Results: 291 health care staff including 135 medical and dental doctors, 4 dental hygienists, 82 paramedics and 70 Administrative staff worked during the study period and 3280 procedures were performed. Out of these, thirty-eight (38) staff members treated 190 verified COVID-19 patients. During the study period 6 dentists (2.06%) and 9 (3.09%) medical doctors, 2 (0.7%) assistants and 3 (1.03%) admin staff were tested positive for the virus. Conclusion: Present study highlights the importance of education and stickiness to the infection control guidelines thus minimizing the risk of transmission of corona virus among the Healthcare professionals in hospitals.
