Highlights

Survey participants had high levels of concern about being injured or killed in a grain bin entry incident.

Most survey participants were aware of grain bin entry hazards.

Education and training efforts should focus on safe grain bin entry practices as well as rescue procedures.

Abstract. Agricultural injury data have shown that grain bin hazards cause many injuries and fatalities every year. To develop effective safety measures, it is necessary to understand farmers’ perceptions of grain bin entry hazards. This survey study was developed and performed to determine farmers’ perceptions of the hazards associated with grain bin entry. The survey was administered both online and at face-to-face agricultural safety events. A total of 162 participants completed surveys, with the majority in New York and Pennsylvania. Most participants were concerned about being injured (77%) or killed (66%) when entering a grain bin. Seventy percent of the participants indicated that they had entered a grain bin alone without an observer, and 60% indicated that they had no written emergency response plan. The participants perceived safety equipment (e.g., gas monitors, lifeline and harness systems, anchor points, respirators, and grain rescue tubes) as valuable, and they were mostly familiar with some of these devices. The participants reported a need for training and short educational videos related to safe grain bin entry. Recommendations for safe grain bin entry should focus on entering bins with an observer present and using lifeline and harness systems, gas monitors, and respirators. Keywords: Grain bin, Hazards, Lifeline, Near miss, Perceptions, Worker safety.

Published: January 2022

We demonstrate a high power Yb-doped burst-mode all-fiber laser system operating at GHz intra-burst repetition rate. To our knowledge, it is the first report utilizing dissipative soliton resonance (DSR) to generate tunable burst-mode rectangular pulses. Due to the tunable duration and the rapid rise/fall time for DSR pulses, a 1-10 ns adjustable burst pulse duration is achieved. The intra-burst with sinusoidal waveform can be tuned from 0.8 GHz to 1.5 GHz and actively modulated by an electro-optic modulator (EOM). Amplified by a three-stage Yb-doped fiber amplifier (YDFA), the output power achieves 304 W at 10 ns of burst duration, and the maximum peak power reaches over 50 kW at 2 ns of burst duration. This laser system is anticipated to be applied to generate high power arbitrary microwave signal.
Random polarization switching in gain-switched VCSELs for quantum random number generation
Authors: Quirce Ana , Valle Angel
Published: January 2022

In this paper, we report an experimental and theoretical study of the random excitation of the linearly polarized modes of a gain-switched VCSEL characterized by having polarization switching under continuous wave operation. We show that equal probability of excitation of both linearly polarized modes can be achieved by adjusting the modulation conditions and the sampling time. Our VCSEL is such that the bistable region associated to the polarization switching is very narrow, indicating that the random process of excitation of the polarizations works independently of the existence of those bistable regions. A characterization of the random polarization switching is performed by analyzing the dependence of the probability of excitation, autocorrelation, and histograms of both polarized signals on the modulation conditions and sampling times. We finally present preliminar results on random number generation using the analyzed system.
Rotation of degree of coherence and redistribution of transverse energy flux induced by non-circular degree of coherence of twisted partially coherent sources
Authors: Wu Gaofeng , Wang Haiyun , Wang Fei , Cai Yangjian
Published: January 2022

It is known that a twisted Gaussian Schell-model (TGSM) beam with elliptical Gaussian amplitude will rotate its beam spot upon propagation because of the vortex structure of the transverse energy flux. In this paper, we study a special kind of twisted partially coherent beams named twisted Hermite-Gaussian correlated Schell model (HGCSM) beam whose degree of coherence (DOC) is non-circularly symmetric but the source amplitude is of the circular Gaussian profile. Our results reveal that the beam spot (average intensity distribution) does not rotate during propagation even if the circular symmetry of the beam spot is broken. However, the DOC pattern shows the rotation under propagation. From the investigation of the transverse energy flux and OAM density flux, we attribute the nontrivial rotation phenomenon to the redistribution of the transverse energy flux by non-circular DOC. Furthermore, based on Hyde‘s approach [J. Opt. Soc. Am. A 37, 257 (2020)10.1364/JOSAA.381772], we introduce a method for the generation of this class of twisted partially coherent sources. The non-rotation of the beam spot and rotation of the DOC are demonstrated in experiment.
Los militares ante la justicia: El Consejo Supremo de Guerra y Marina y las responsabilidades del desastre (1922-1924)
Authors: Alía Miranda Francisco
Published: January 2022

El general Aguilera, ex ministro de la Guerra (1917), fue el presidente del Consejo Supremo de Guerra y Marina entre 1921 y 1924, por lo que se convirtió en el principal responsable de incorporar, estudiar, debatir e impartir justicia en el asunto de las responsabilidades de los militares en el desastre de Annual. El Expediente Picasso, instruido desde agosto de 1921 con carácter meramente informativo para depurar las posibles responsabilidades, fue elevado en 1922 al Consejo Supremo de Guerra y Marina con el fin de dirimir las responsabilidades penales de los militares implicados en la campaña militar que acabó en el desastre. El asunto de las responsabilidades tomó un nuevo rumbo en la sede del máximo organismo de la justicia militar, que intentó buscar a todos los responsables y repartir las culpabilidades entre todos los implicados, incluso entre los jefes militares excluidos deliberadamente del Expediente Picasso. La implacable búsqueda de responsables políticos y militares tanto en las Cortes como en el Consejo Supremo resultó determinante en el golpe de Estado del 13 de septiembre de 1923. El rey Alfonso XIII, según todos los indicios, pudo jugar un destacado protagonismo en el origen del régimen dictatorial con el fin de quitarse de en medio la pesadilla de las responsabilidades del desastre de Annual. Además, se incorpora la opinión del entonces joven comandante de la Legión Francisco Franco Bahamonde sobre las causas y responsabilidades de Annual, expresada en una serie de cartas inéditas escritas entre 1921 y 1923.
ejército español en vísperas de Annual
Authors: Puell de la Villa Fernando
Published: January 2022

El artículo intentará responder a la siguiente pregunta: ¿hasta qué punto incidió la estructura orgánica, la doctrina táctica, la capacitación operativa y la dotación armamentística del ejército español, tanto las del peninsular como las del desplegado en Marruecos, sobre el desastre de Annual? A tal objeto, se analizarán dichos factores en el contexto de la segunda década del siglo xx, pudiendo llegarse a la conclusión de que efectivamente fueron determinantes en la errónea planificación y desarrollo de la operación dirigida al sometimiento del Rif oriental y para que se produjese el precipitado abandono de aquella posición y el consiguiente desplome de la Comandancia General de Melilla.
Los estados mayores del ejército ante el 18 de julio
Authors: García Álvarez-Coque Arturo
Published: January 2022

Después de una reflexión historiográfica sobre la relevancia del estudio de los militares de 1936, tratamos como estudio de caso al grupo de jefes de los estados mayores. Es bien sabido que sólo tres de los doce generales de división con mando de tropas se sublevaron en julio de 1936. Algunos autores han sostenido que los jefes de los estados mayores (en un nivel jerárquico inmediatamente inferior a los generales) participaron mayoritariamente en la conspiración de la primavera de 1936, y que su papel fue clave allí donde la sublevación triunfó. En este artículo se demuestra que, por el contrario, fue minoritaria su participación en la conspiración. Fue asimismo una minoría entre ellos la que se sublevó en un primer momento, aunque finalmente todos menos tres terminaron uniéndose a la rebelión contra el Gobierno. Hemos considerado como causa de los errores historiográficos la posible pervivencia de una visión simplista sobre las actitudes de los militares ante la crisis de julio de 1936.
De Chicago a Kent State: un retrato musical de las protestas contra la Guerra de Vietnam
Authors: García Martín Juan Andrés
Published: January 2022

La participación de Estados Unidos en la guerra de Vietnam generó reacciones de apoyo y rechazo en la sociedad estadounidense. La movilización, en principio dispersa, alcanzó su punto álgido en las protestas acaecidas en la Convención del Partido Demócrata de Chicago en 1968 y en la Universidad de Kent State en 1970. La represión que siguió a estas manifestaciones añadió nuevos argumentos a unas protestas que ya no solo denunciaban la participación en el conflicto sino la restricción de libertades. Todos estos acontecimientos generaron una abundante producción musical por parte de diversos cantautores en forma de canciones de protesta.

A través de un análisis de los contenidos líricos de estas composiciones, este artículo analiza el retrato musical de estas protestas y de la posterior represión. Ello permitirá determinar las preferencias temáticas y clasificar las canciones de acuerdo con esta categorización, así como concretar las cuestiones objeto de denuncia. De este modo, podremos vislumbrar el posicionamiento de los compositores y la descripción de la situación que atravesaba el país.
El desarrollo de la relación China-Francia: del reconocimiento mutuo a la proyección de la Iniciativa Cinturón y Ruta de la Seda
Authors: Rocha Pino Manuel de Jesús
Published: January 2022

En la investigación se analizan los principales elementos estructurales que ha desarrollado la relación sino-francesa a partir de sus políticas de reconocimiento mutuo, así como la percepción en Francia sobre la instrumentación de la Iniciativa Cinturón y Ruta de la Seda en su territorio. Desde el establecimiento de sus relaciones diplomáticas en 1964, la relación sino-francesa ha sido instrumentada de acuerdo con algunos intereses nacionales que han definido sus características estructurales: 1) el interés de Francia por mantener una relación «privilegiada» con China en el contexto europeo; 2) el interés por mantener relaciones comerciales activas; 3) el interés de China por ser reconocida por una potencia occidental (económica, cultural, nuclear y perteneciente al Consejo de Seguridad de Naciones Unidas); 4) el interés de Francia por ser una orientadora de las políticas de la Unión Europea hacia China. En la investigación se identifica cómo estas características han sido instrumentalizadas por los distintos gobiernos de la República Francesa y la percepción generada por los gobiernos de la República Popular China.

Published: January 2022

El propósito de este artículo es realizar un estado de la cuestión del africanismo castrense, un grupo militar forjado en el contexto colonial de las Campañas de Marruecos (1909-1927) y decisivo para comprender la historia contemporánea española del siglo xx. Para ello se ha procedido a una revisión sistemática de la bibliografía existente en torno al tema para estudiar su tratamiento a lo largo de los últimos años. De esta forma se pretenden desgranar las diferentes características que se atribuyen a estos militares para observar los puntos débiles de la situación actual de las investigaciones. A la par se propondrán algunas posibles vías de estudio y tratamiento del tema.
proyectos de desembarco en Alhucemas
Authors: Díez Rioja Ramón
Published: January 2022

El presente artículo es el resultado de una investigación centrada en las líneas de acción que siguieron los tres últimos gobiernos de la Restauración en el Protectorado de Marruecos, una vez consumado el derrumbe de la Comandancia General de Melilla en el verano de 1921. Del mismo modo explora la actuación de Primo de Rivera, desde que perpetró el golpe de Estado en septiembre de 1923 hasta que se ejecutó la operación de desembarco en Alhucemas en septiembre de 1925. Entre 1921 y 1925 se sucedieron varias alternativas en el plano estratégico. Por un lado, se dio preferencia a la vía militar, planteándose hasta en cuatro ocasiones llevar a cabo un desembarco en la bahía de Alhucemas: febrero de 1922, agosto de 1922, julio de 1923 y finalmente el que se llevó adelante en septiembre de 1925. En el extremo opuesto, durante las presidencias de José Sánchez Guerra y Manuel García Prieto, entre marzo de 1922 y septiembre de 1923, se defendió la acción «puramente civil», priorizando así la vía de la negociación. Hubo una tercera línea de actuación, cuando a partir de septiembre de 1924 el dictador llevó adelante una «rectificación de frentes» que consistió en el repliegue de las fuerzas a líneas más fuertes y seguras, con el objeto de reducir efectivos y gastos.

El objetivo de este estudio es desvelar los motivos de la implantación del primer economato laboral conocido en Asturias. Para ello se ha recurrido a protocolos notariales, correspondencia custodiada en el Archivo Histórico Nacional de España y en el Archivo Histórico de Asturias, así como fuentes hemerográficas. La conclusión es que a mediados del siglo xix confluyen en la incipiente industrialización asturiana varios factores que explican el establecimiento de un precoz truck system: la crisis de subsistencias, el reflejo de las teorías filantrópicas y la situación particular de una empresa en estado de necesidad terminan configurando un modelo muy temprano, azaroso y peculiar de economato laboral.

difícil equilibrio entre la legalidad internacional y la política exterior
Authors: Lorenzo Cuesta José Antonio
Published: January 2022

Este artículo pretende demostrar que la participación de las Fuerzas Armadas españolas, llevada a cabo en el año 2003 en el territorio iraquí, se desarrolló en un escenario geoestratégico en el que la Administración norteamericana quiso afianzar su presencia como actor principal en un mundo envuelto en complejas relaciones internacionales y tras un siglo que tanto alumbró la desaparición del comunismo de la Unión Soviética, como asistió a la consolidación del fundamentalismo islámico. Mediante la utilización de los métodos sintético y deductivo, este trabajo llevará a la comprensión del alcance real de la presencia de las tropas españolas en Irak, así como de su verdadero significado político y estratégico. Tras un recorrido por los diferentes epígrafes que conforman este artículo, podrá concluirse que los ciudadanos iraquíes fueron los únicos beneficiados de esta acción, puesto que las relaciones exteriores bilaterales entre España y los Estados Unidos se vieron especialmente afectadas.
Varietal Preference And Efficacy Of Various Chemicals Against Red Pumpkin Beetle (

CUCUMIS SATIVUS) Cultivars
Authors: Khan789 Mehran
Published: January 2022

Experiments were conducted to determine the resistance level of different cultivars and study the efficacy of various synthetic insecticides against red pumpkin beetle (
Aulocohphora foveicollis) at the New Developmental Malakandir Farm, the University of Agriculture Peshawar, during 2018. In the first experimental trial, data were collected on the mean population density of red pumpkin beetle on three cultivars (Desi, Super Green and Madam-560) of cucumber crop. While in the second experiment, three insecticides (Carbaryl, Cypermethrin, Malathion) and an Untreated/Control were used to study the effect of these insecticides on Desi (susceptible) and Madam 560 (resistant) cultivars regarding red pumpkin beetle on cucumber cultivar. Randomized Complete Block Design (RCBD) was used in this experiment. The data on the relevant parameters were recorded at weekly intervals for eleven (1
st experiment) and four weeks (2
nd experiment) i.e. till termination of the experiments. During first experiment, it was observed that significantly lowest population density of red pumpkin beetle (0.82) per plant and highest yield (8981.3 kg ha
-1) was observed from Madam 560, while significantly highest mean population density of red pumpkin beetle (4.06) per plant and lowest yield (7313.7 kg ha
-1) was obtained from Desi cultivar. Significantly maximum mean number of red pumpkin beetle plant
-1 was recorded in the seventh week (29 May) from Desi, Super Green and Madam 560 cultivars with 6.41, 4.50 and 1.62 beetle plant
-1, respectively. During the cropping season, mean population density of red pumpkin beetle plant
-1 reached its peak in the seventh week (29 May). After 7
th week, a gradual decline was occurred in the mean population density of red pumpkin beetle plant
-1. In second experiment, lowest mean population density of red pumpkin beetle adults plant
-1 (0.12), area of consumption (3.12 mm
2), percentage weight loss (1.60 %) and highest yield (21555 kg ha
-1) was recorded from Madam 560 treated with Carbaryl, while highest mean population density of red pumpkin beetle adult plant
-1 (7.09), area of consumption (36.11 mm
2), percentage weight loss (17.27%) and lowest yield (7247 kg ha
-1) was recorded from untreated Desi cultivar. It was followed by untreated Madam 560 cultivar where 5.40, 25.92 mm
2, 13.20% and 8766 kg ha
-1. Madam 560 is significantly better cultivar than Super Green and Desi, as this cultivar results in lowest population density of red pumpkin beetle and highest yield of cucumber fruit. Carbaryl is significantly better as compared to Malathion and Cypermethrin because it reduces the population of red pumpkin beetle.

Models are created to predict the current sale price of a comic across various grades. Inputs to the models are one or more historical sale prices and their corresponding grades, and models produce a multiplier for a historical sale as an estimate of the current fair-market value. Models are realized as a table of price predictions for every possible grade. Predictions from these models average within 1\% of relative value with variance of 0.07.
The Prevalence and Predictors of Early Girl Child Marriage in the Nabdam district of the Upper East Region Ghana
Authors: Mohammed Baba Yahaya
Published: January 2022

Child marriage remains a challenge in Ghana. Over the years, government and development partners have made various commitments and efforts to curb the phenomenon of child marriage. However, there is little empirical evidence on the predictors, norms and practices surrounding the practice to support their efforts, a gap this study sought to fill.
Methods: The study adopted an explanatory research design and quantitative research approach in which simple random and convenient sampling technique were used to select ninety-three respondents from Kongo-Pitanga of Nabdam district. The study used structured questionnaires as a tool for data collection.
Findings

: From the qualitative data, the study identified poverty, teenage pregnancy, and cultural norms such as, exchange of girls for marriage and pressure from significant others as the drivers of child marriage.
Conclusion: The findings show that various socio-economic and cultural factors such as education, teenage pregnancy, and poverty influence child marriage. Hence, efforts to curb child marriage should be geared towards retention of girls in school, curbing teenage pregnancy, empowering girls economically, enforcing laws on child marriage in Ghana, as well as designing tailored advocacy programs to educate key stakeholders and adolescent girls on the consequences of child marriage. Additionally, there is the need to address socio-cultural norms/practices to help end child marriage.

Riemann Zeta Based Surge Modelling of Continuous Real Functions in Electrical Circuits
Authors: Jibril Mustefa
Published: January 2022

Riemann zeta is defined as a function of a complex variable that analytically continues the sum of the Dirichlet series, when the real part is greater than unity. In this paper, the Riemann zeta associated with the finite energy possessed by a 2mm radius, free falling water droplet, crashing into a plane is considered. A modified zeta function is proposed which is incorporated to the spherical coordinates and real analysis has been performed. Through real analytic continuation, the single point of contact of the drop at the instant of touching the plane is analyzed. The zeta function is extracted at the point of destruction of the drop, where it defines a unique real function. A special property is assumed for some continuous functions, where the function’s first derivative and first integral combine together to a nullity at all points. Approximate reverse synthesis of such a function resulted in a special waveform named the dying-surge. Extending the proposed concept to general continuous real functions resulted in the synthesis of the corresponding function’s Dying-surge model. The Riemann zeta function associated with the water droplet can also be modeled as a dying–surge. The Dying- surge model corresponds to an electrical squeezing or compression of a waveform, which was originally defined over infinite arguments, squeezed to a finite number of values for arguments placed very close together with defined final and penultimate values. Synthesized results using simulation software are also presented, along with the analysis. The presence of surges in electrical circuits will correspond to electrical compression of some unknown continuous, real current or voltage function and the method can be used to estimate the original unknown function.Keywords

Published: January 2022

This article is a reflection on a collaborative learning process between a university department and a community-based organisation in creating intergenerational learning platforms. The process entailed the coming together of school learners, university students and community elders in a university setup. Participatory Appreciative Action Learning Research was employed. Purposive sampling was used. Data collection methods approach included were semi-structured interviews, one on one individual interviews and focus group discussions. Three generations, namely school learners, university students, and community elders, participated in selecting the learning areas. These included Indigenous Knowledge Systems (IKS), nature conversation topics, peace-building, manners and Ubuntu, social entrepreneurship, and health issues. The purpose of this initiative was to transfer knowledge, skills, norms, wisdom, and values, among generations, through a collaborative effort between an academic institution and a community. It was hoped that this would provide opportunities for lifelong learning and sharing of knowledge and experience among generations. The collaborative intergenerational learning (IGL) process opened with a series of focused discussions about how to bring to mainstream education (both basic and higher education), platforms for learning that should be inclusive of all forms of knowledges, including indigenous knowledge (IK).
The ruptures in our rainbow: Reflections on teaching and learning during #RhodesMustFall
Authors:   University of KwaZulu-Natal, Hlathswayo Mlamuli
Published: January 2022

In this paper, I attempt to explore and theorize the “ruptures” in our rainbow nation through foregrounding higher education in general and teaching and learning practices in particular. I rely on Morrow (2009), in particular his intellectual and philosophical contributions on epistemological access to make two contributions. Firstly, I argue that South African higher education urgently needs to re-conceptualize the theoretical understanding of “access” beyond formal, simplistics notions. Secondly, I hope to show how a re-adoption of Morrow’s understanding of epistemological access can enable progressive engagements between academics and students in both having respect for and a critical understanding of the different disciplines and knowledge(s) in higher education. I suggest that a return to Morrow’s idea of epistemological access will not only enable us to make the make the necessary “repairs” to our rainbow nation but it will also enable us to better respond to the progressive and innovative calls in teaching and learning that contemporary South African higher education greatly demands of us
KUŞ İMGESİNİN SÖYLENBİLİMDE VE SANATTA TEMSİLİ ANAERKİLLİK-ATAERKİLLİK İKİLİĞİ BAĞLAMINDA KUŞ İZLEĞİ

Published: January 2022

Mitoloji-Söylenbilimde kuşlar ve sfenks-kuş ile birkaç farklı hayvanın birlikte gösterildiği fantastik yaratıklar-, hem uçma eylemiyle insanları özendiren bir varlık olarak hem de sanat ve edebiyatta bir mesaj vermek için daima etkili olmuştur. Kuş betimi, aynı zamanda kadın ve erkek arasındaki güç mücadelesini göstermek için kullanılan birçok metafordan biridir. Tarihin erken dönemlerinde-anaerkil- şahin gibi güçlü bir kuşun kadınla özdeş olması dışın-da, kadınlar sanatın birçok dalında günümüzde olduğu gibi tarih boyunca genellikle güzel, narin ve kırılgan varlıkların sembolü olan kuşlarla özdeş tutulmuştur. Kadınlara isim verilir-ken de aynı yaklaşım söz konusudur; narin bir kuş türü olan kumru, “Kumru” olarak kadın ismiyken güçlü bir kuş türü kartal, “Kartal” olarak erkek ismidir. Bunun yanında birçok dö-nüşüm-metamorfoz- mitosunda da özne, Leda-Kuğu örneğinde olduğu gibi kadındır ve çok bilinen bir yapıt olan “Kuğu Gölü” balesinde de kuğu kadınla özdeştir. Sfenksler söz konusu olduğunda, sanatta temsillerinde kadın ile ilişkili- özdeş olduğu görülmektedir. Çalışma, sanatsal yaratımın fantastik ürünü olan sfenks ile Antik Yunan Mitolojisinden başlayarak, kadın tanrıçalar ve kuş ilişkisinin, mitoslar aracılığıyla sanatta ve edebiyatta nasıl yansıtıldı-ğını, kuş imgesinin görsel temsilleri ve edebiyattaki temsillerini seçilmiş örneklerle ortaya koymayı amaçlamaktadır.
Patient-Driven Findings of Genetic Associations for PANS and PANDAS
Authors: Horvath Robert Steve , Keating Samuel
Published: January 2022

Background: There are presently very few genetic studies for PANS (Pediatric Acute-Onset Neuropsychiatric Syndrome) or PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections). More work in genetic associations for PANS and PANDAS (P/P) is needed to increase understanding of these debilitating childhood disorders that have a range of presentations.Objective: This work represents a novel approach that aims to determine genetic associations between P/P and other diseases, disorders and traits (hereafter referred to as phenotypes).Methods: Consumer genetic data (23andMe, AncestryDNA) for 155 patients with P/P were obtained from consenting parents over a period from 2018 to 2020. An analysis plan for this work was registered at Open Science Framework, additional genotypes imputed using Impute.me, and polygenic risk scores for 1,702 phenotypes calculated for each of the 155 P/P patients.Results: One-sample t-tests performed across the 155 individual risk scores revealed that P/P is statistically significantly associated with 21 different groups of Single Nucleotide Polymorphisms (SNPs) that are in turn associated with 21 phenotypes. Some of the 21 phenotypes (see Table 3) are previously known to be related to or associated with P/P: a group of SNPs associated with Tourette’s Syndrome, and another group associated with Autism Spectrum Disorder or Schizophrenia, and a third associated with “feeling nervous” yielded t-tests with p values of 1.2x10-5, 1.2x10-11 and 1.0x10-5 respectively for association with the P/P data. This validated our analysis methodology. Our analysis also revealed novel genetic associations such as between P/P and plasma anti-thyroglobulin levels (p=1.3x10-7), between P/P and triglycerides (p=5.6x10-6), and between P/P and Lewy body disease (p=7.8x10-6), inviting further investigation into the underlying etiology of P/P.Conclusion: P/P is associated with many phenotypes not previously recognized as being connected to P/P. Further work on these connections can lead to better understanding of P/P.

This work proposed a study of a direct enzymatic of vanillin formation by using rumen liquid which has enzymatic capability for tissue disruption of vanilla green pods to avoid the curing process. Application of enzymes during the formation of vanilla aromas and its extraction present nice opportunity to improve productivity, as the enzymatic reaction possibly substitute the microbial process in the traditional fermentation. Green vanilla pods were applied for the direct enzymatic extraction of vanillin, while liquid rument provide cell wall degrading enzyme in order to support the hydrolysis process (destruction) of cell wall. Glucovanillin were contacted with the β-glucosidase in the green pods due to the desruction of the cell wall, followed by the formation of glucovanillin into vanillin. Vanillin content of vanilla green pods was found higher in which by treating the vanilla green pods at 30 °C.

LNG (Liquid Natural Gas) is a liquefied natural gas, with composition of 87% - 96% methane, 1,8-5,1% ethan, 0,1-5,1% propane and other compounds. The composition of natural gas (LNG formation) varies depending on the source and the process of its formation. Methane gas in LNG has odorless, non-corrosive and non-toxic properties (Air Products, 1999). LNG is basically an alternative method to deliver gas from producer to consumer. When cooled to -162˚C at 1 atm pressure, natural gas becomes liquid and its volume decreases up to 600 times (Handbook of Liquefied Natural Gas, 2014). With such a large volume reduction, liquefied natural gas (LNG) can be transported through the Tanker Ship and the ISO Tank Truck. PT Badak NGL has 3 (Three) T.U.K.S (Terminal For Ownership) As Tanker Ship Facilities and 1 (One) LNG Filling Station as a means of filling LNG to ISO Tank. Development of business process of PT. Badak NGL leads to an increase in LNG filling Station capacity. Along with the plan to increase the filling station capacity, the problem of BOG (Blow of Gas) wastage along with some LNG to ground flare becomes a serious concern. When the number of fillling stations is only 1 (one) station, the BOG wasted condition is not significant. However, with plans to increase the number of filling stations, BOG wasted need to be considered to be fully utilized. Therefore, there is a thought to utilize BOG to become more economic value, through the design of blowdown line on LNG ISO Tank filling station. In the Design of this line Blowdown, Using Pipe Ø2 "(PIPE BE 40S SS A312-TP305 SMLS) interconnecting with Pipe Ø6" (PIPE BE 40S SS A312-TP305 SMLS) BOG Header of new Filling Station under construction (Beginning January 2018 ).

In Badak LNG the role of the cooling water pump is very important, and becomes the main support for transferring sea water where the water is used in the cooling process of industrial machinery or as emergency safety for firefighters. Water pump cooling has a hayward strainer that serves to filter water with a smaller filter so that the cooling water that is sent is completely free of dirty water. The purpose of this final project is to find out the main causes of the performance degradation of the EF cooling water pump due to the barrier to the hayward strainer which results in lower pressure on the cooling water. The methodology applied was based on field observations and conducted a solidwork simulation test. Field observations show that when more than one hayward strainer is in backwash, the effectiveness of backwash release decreases because the main disposal of the hayward strainer becomes one. The solidwork simulation found that the pressure on the Hayward train E strainer was high enough to create back pressure and limit the flow of the Hayward strainer outlet. By performing actual simulations by only running only one exhaust system at Hayward train E trainer has improved performance on the hayward strainer system. The performance analysis of the cooling water pump was carried out to determine the cause of the pump pressure drop on the hayward strainer and it was found that the main cause of performance was due to back pressure disposal, the pressure was increasing at each outlet of the Hayward strainer which had more distance to the outlet drain. Taking into account the problem of back pressure, separating the train E and F cooling water pump lines is a good choice. After simulating solid work, the separation of the E train line and the F colling water train shows an increase in the performance of the cooling water pump system because the Hayward strainer runs well so that the pump pressure is maintained for the industrial engine cooling needs.
