Studies on atmospheric density were very important to obtain a correction factor for the atmospheric density model. Thus, improvement of atmospheric models accuracy, i.e. CIRA, JASCHIA, NRLMSISE, became important in its application for re-entry prediction, satellite tracking and mitigation of the collisions probability between active satellites with space debris. GPS equipment installed in LAPAN-A2 indirectly measured the upper atmospheric density variation in-situ from the satellite orbit path. Notwithstanding the measurement had a lower temporal resolution than using accelerometer, but still gives better resolution than using Two-Line Element (TLE) data. This study had successfully determined upper atmospheric density variation with a 10 second resolution using LAPAN-A2 GPS data. The LAPAN-A2 GPS data validated using In-track Radial Cross-track (RIC) had ± 2 km error compared to the TLE data. It was also found that there was influence of solar activity on atmospheric density changes obtained from the LAPAN-A2 GPS data. AbstrakStudi kerapatan atmosfer atas sangat penting untuk memperoleh faktor koreksi dari suatu model kerapatan atmosfer. Peningkatan akurasi dari model atmosfer yang telah ada (CIRA, JASCHIA, NRLMSISE) sangat penting dalam penerapannya untuk prediksi re-entry, penjejakan satelit dan prakiraan kemungkinan terjadinya tabrakan antara satelit aktif dengan sampah antariksa. Peralatan GPS yang terpasang di satelit LAPAN-A2 secara tidak langsung dapat melakukan pengukuran in-situ perubahan kerapatan atmosfer atas dari orbit yang dilaluinya, meskipun tingkat resolusi temporalnya masih lebih rendah dibandingkan menggunakan instrumen akselerometer tetapi masih jauh lebih baik dibandingkan menggunakan data Two-Line Element (TLE). Studi ini telah berhasil memperoleh variasi kerapatan atmosfer atas dengan resolusi 10 detik menggunakan data posisi GPS LAPAN-A2. Selain itu, diperoleh pula tingkat kesalahan dalam koordinat satelit (Radial Intrack Crosstrack - RIC) data TLE terhadap data posisi GPS LAPAN-A2 sebesar ± 2 km. Selain itu terlihat pula pengaruh aktivitas matahari terhadap perubahan kerapatan atmosfer atas yang diperoleh dari data posisi GPS LAPAN-A2

Published: February 2018

Large Magellanic Cloud (LMC) is a home of thousands of star clusters with various ages and metallicities. This galaxy also becomes the ideal laboratory for understanding binary cluster population which is large in number. One of the binary cluster candidates within the galaxy is OGLE-LMC 316/317 which is located near the bar of LMC. The age of OGLE-LMC 317 had not been determined, while the age of OGLE-LMC 316 was doubted. Whereas, age is an important parameter in the study of system binarity. In this study, photometry data from Optical Gravitational Lensing Experiment (OGLE) was used to construct color magnitude diagram and to estimate the age of OGLE-LMC 316/317. The results were the estimated ages of OGLE-LMC 316 and OGLE-LMC 317 which were 63 and 160 million years respectively. Based on these results, OGLE-LMC 316/317 system which has projected separation of 5 pc can be considered as primordial and coeval binary star cluster. ABSTRAK Large Magellanic Cloud (LMC) merupakan rumah bagi ribuan gugus bintang dengan beragam usia dan metalisitas. Galaksi ini juga menjadi laboratorium ideal untuk memahami populasi gugus ganda yang melimpah jumlahnya. Salah satu kandidat gugus ganda di dalamnya adalah OGLE-LMC 316/317 yang terletak di dekat batang LMC. Usia OGLE-LMC 317 belum diketahui, sementara usia OGLE-LMC 316 masih disangsikan. Padahal usia adalah parameter penting untuk mempelajari kegandaan dari sistem ini. Pada studi ini, data fotometri Optical Gravitational Lensing Experiment (OGLE) digunakan untuk membangun diagram warna magnitudo dan memperkirakan usia OGLE-LMC 316/317. Hasilnya, OGLE-LMC 316 diperkirakan berusia 63 juta tahun sementara OGLE-LMC 317 setidaknya berusia 160 juta tahun. Berdasarkan hasil ini, sistem OGLE-LMC 316/317 yang memiliki jarak pisah di bidang langit sebesar 5 pc dapat dianggap sebagai gugus ganda primordial dan coeval.
EFEK CME HALO PENUH PADA IONOSFER LINTANG RENDAH DARI DATA GPS BAKO DI CIBINONG [EFFECT OF FULL HALO CME ON LOW LATITUDE IONOSPHERE FROM BAKO GPS DATA IN CIBINONG]
Authors: Muttaqien Fakhrizal , Muslim Buldan
Published: February 2018

A full halo coronal mass ejections (CMEs) are most energetic solar events that eject huge amount of mass and magnetic fields into heliosphere with 360o angular angle. The full halo CME effect on the ionosphere can be determined from the ionospheric total electron content (TEC) derived from GPS data. GPS data from BAKO station in Cibinong, satellite orbital data (brcd files) and intrumental bias data (DCB files) have been used to obtain TEC using GOPI software. Analysis of  the full halo CME data, Dst index, and TEC during October 2003 and February 2014 showed that the full halo CME could cause ionospheric disturbances called ionospheric storms. Magnitude and time delay of the ionospheric storms  depended on the full halo CME speed. For the high-speed full halo CME, the negative ionospheric storm generally occured during recovery phase of the geomagnetic storm. When the initial phase of geomagnetic disturbance with increasing Dst index more than +30 nT, the ionospheric storm occured during main phase of geomagnetic disturbance although the main phase of geomagnetic disturbance did not reach geomagnetic storm condition. ABSTRAKCoronal mass ejection  (CME) halo penuh merupakan peristiwa matahari  berenergi tinggi, yang menyemburkan massa dan medan magnet ke heliosfer dengan sudut angular sebesar 360º. Efek  CME halo penuh pada ionosfer dapat diketahui dari Total Electron Content (TEC). Data GPS BAKO di Cibinong, data orbit satelit (file brcd) dan data bias instrumental (file DCB) dapat digunakan untuk penentuan TEC menggunakan software GOPI. Analisis data CME halo penuh, indeks Dst, dan TEC selama bulan Oktober 2003 dan Februari 2014 menunjukkan bahwa CME halo penuh dapat menimbulkan gangguan ionosfer yang disebut badai ionosfer. Besar dan selang waktu badai ionosfer setelah terjadinya CME, tergantung pada kelajuan CME halo penuh. Untuk CME halo penuh berkelajuan tinggi, badai ionosfer negatif umumnya terjadi pada fase pemulihan badai geomagnet. Jika fase awal gangguan geomagnet diawali dengan peningkatan indeks Dst melebihi +30 nT, maka badai ionosfer dapat terjadi pada fase utama gangguan geomagnet walau gangguan geomagnet setelah  fase awal tidak mencapai kondisi badai geomagnet.

The proceeding semiotic paradigms were strategic discourses communicated to dominate some facets of human endeavors serving, perhaps, as signals to operational capacities of Airtel®. Halliday’s concepts of the Paradigmatic Order and Circumstantial facilities of the Transitivity system were applied to seven ads of the Always On to assist in deriving both structural and semantic values from the switching linguistic elements. Tables and a graph provided supports for the analysis as indicators of the recurring components of the analyzed structural choices. The study showed that Always On is synonymous with Airtel in terms of operational consistency. It revealed further that creativity was not limited to the phrases proceeding Always On but that the choice inventions were extended to background images playing supportive roles in the persuasion. The Circumstantial functioned as cause, manner and role with reliable service provisions. The switches provided recipients avenues to generate diverse meaning potential that could naturally stimulate individuals to consumption. The study concluded that the alternating devices did not only fascinate persuasion but also demonstrated systemic creativity of enlightenment.

Authors: Karman Nfn
Published: February 2018

This article deals with how daily newspapers of Indonesia frame reality of the collective action of Muslims. That action becomes a magnet for national and international mass media because involving a large number of Muslim, and has a problem complexity (legal, politic, religion) and political interests (contestation for Jakarta governor). The media gets involved in that complexity because they are harnessed as a political instrument, by conducting framing. This study aims to find daily newspaper frame by analyzing the content qualitativly. Those newspapers are Kompas, Republika, Suara pembaruan, and Media Indonesia during November 2016. By analyzing their editorials, we find that their frames regarding Muslim collective action are different to each other. Even, frames of Republika and Suara Pembaruan are contested. Republika regards the Muslim action as a respond to get justice and basic right because of their religion blasphemy. Republika considers it as a legal issue. Suara Pembaruan views the Muslim action as a political issue (governor election of DKI Jakarta), which makes use of religion issue. Media Indonesia sees the action as a political issue as well. Kompas regards it as political and religion issue. We conclude that although expected to be impartial –as part of democratic values, mass media keep in-partiality in crucial issues e.g., religion. This study gives our understanding that mass media can be partial in the certain contexts. Tulisan ini membahas bagaimana surat kabar harian membingkai realitas aksi umat Islam. Aksi tersebut menarik pemberitaan media massa nasional dan internasional karena melibatkan muslim dalam jumlah besar, memiliki kompleksitas persoalan (hukum, politik, agama, dan kepentingan), yaitu kontestasi pemilihan gubernur Jakarta 2017. Media terlibat dalam kompleksitas tersebutdan digunakan sebagai instrumen, yaitu politik pemberitaan. Kajian ini bertujuan menemukan bingkai surat kabar harian nasional dengan melakukan analisis isi kualitatif terhadap surat kabar nasional, yaitu: Kompas, Republika, Suara Pembaruan, dan Media Indonesia selama periode November 2016. Dengan menganalisis tajuk rencana mereka, kajian menemukan bahwa frame surat kabar di Indonesia berbeda satu sama lain. Frame surat kabar Republika dan Suara Pembaruan bahkan saling bertentangan. Republika menganggap aksi umat Islam sebagai respon untuk memperoleh keadilan dan hak asasi karena penistaan agama mereka (masalah hukum). Suara Pembaruan melihat aksi sebagai masalah politik (pemilihan gubernur DKI Jakarta) yang menggunakan isu agama. Media Indonesia melihat aksi juga sebagai masalah politik. Kompas melihat aksi sebagai persoalan agama dan politik. Kajian  menyimpulkan bahwa walaupun diharapkan tidak memihak sebagai bagian dari nilai-nilai demokrasi, media massa tetap saja memihak dalam isu yang krusial seperti agama. Penelitian ini memberikan pemahaman bahwa media umum sekalipun bisa menjadi media partisan pada konteks tertentu.

Development of High Pressure Injection Technology for Normal Hydraulic Injection Molding Machines
Authors: Song M. C. , Liu Y. , Chang H.
Published: February 2018

Previous studies have shown that enhancing injection pressure can help improve the precision and mechanical properties of molding products, and reduce their shrinkage. But for now the ordinary hydraulic injection molding machine cannot generally meet the requirements of high pressure injection. To improve the injection pressure, the pressurizing module and the hydraulic circuit were designed, and their influence on the product quality was explored via molding experiments. The relationship between the system pressure of injection molding machine and the injection pressure was demonstrated. The experimental results showed that the maximum injection pressure of the injection molding machine with the pressurizing module was improved from 204 MPa to 320 MPa, up 56.86 %. The lack of materials, bubbles, sags of products were gradually weakened until finally disappeared with increasing the injection pressure. The pressurizing module was convenient to be assembled into or removed from the injection molding machine without damaging the original structure, and the state of pressurizing or no pressurizing could be transformed easily during the injection molding process. These results indicated that this technology was easy to be popularized and applied.
Cross-Linked Hydrophobic Starch Granules in Blends with PLA
Authors: Fuchs J. , Feldmann M. , Aßmann C. , Vorwerg W. , Heim H.-P.
Published: February 2018

The majority of native starch is used in the food sector and in the paper industry. Only a small amount is used in polymer engineering. One reason for the reluctance of the plastics processing industry to use starch as a filling material in polymer blends is the unsatisfactory mechanical behavior of starch when combined with thermoplastics. Another reason is the hydrophilicity of starch. In order to make these materials capable of competing, an amelioration of the mechanical properties is compulsory. By means of modifying the native starch and optimizing the compounding process, it is possible to improve the performance of starch blends, and, thus, increase the number of application areas of these materials. For this reason, native starch was modified with a cross-linking agent using a laboratory mixer. Subsequently, the modified starch and poly(lactic acid) were compounded using a co-rotating twin screw extruder. Cross-linking of the native starch in the laboratory mixer resulted in an increase in the mechanical strength of the starch blends. In addition, the blends with cross-linked starch displayed lower moisture absorption levels than blends with native starch as a filling material.

The effect of the presence of titanium dioxide in two new imines, (E,E)-(butane-1,4-diyl)bis(oxybutane-4,1-diyl) bis(4-{[(benzo[d][1,3]thiazol-2-yl)methylidene]amino}benzoate) (SP1) and (E)-N-[(benzo[d][1,3]thiazol-2-yl)methylidene]-4-dodecylaniline (SP2), on the properties and stability of imine:TiO2 composites for organic device applications were examined. The investigated titanium dioxide (in anatase form, obtained via the sol–gel method) exhibited a surface area of 59.5 m2/g according to Brunauer–Emmett–Teller theory, and its structure is a combination of both meso- and microporous. The average pore diameter calculated by the Barrett–Joyner–Halenda method was 6.2 nm and the cumulative volume of pores was 0.117 m3/g. The imine SP1 exhibited columnar organization (Col), while SP2 revealed a hexagonal columnar crystalline phase (Colhk). The imine:TiO2 mixtures in various weight ratio (3:0, 3:1, 3:2, 3:3) showed a lower energy gap and HOMO–LUMO energy levels compared to pure TiO2. This implies that TiO2 provides not only a larger surface area for sensitizer adsorption and good electron collection, but also causes a shift of the imine energy levels resulting from intermolecular interaction. Also the temperature of the phase transition was slightly affected with the increase of TiO2 concentration in imine-based composites. The changes observed in the Fourier transform middle-infrared absorption (FT-MIR) spectra confirmed the significant influence of TiO2 on structural properties of both investigated imines. Similar interactions of oxygen vacancies existing on the TiO2 surface with SP1 and SP2 were observed. The imine:TiO2 mixtures showed good air stability and reusability, which demonstrates its potential for organic device applications.

Authors: Huang Yu-Chieh , Nguyen An , Gräßle Simone , Vanderheiden Sylvia , Jung Nicole , Bräse Stefan
Published: February 2018

In the presented study, dithi(ol)anylium tetrafluoroborates are added to α,β-unsaturated ketones in a Michael-type reaction yielding diverse substituted ketene diothi(ol)anes. The reactions proceed at room temperature in 1 or 13 h without the need of further additives. The presented procedure is in particular useful for dithi(ol)anylium tetrafluoroborates without electron-withdrawing groups in α-position. This is advantageous with respect to previous approaches, which were limited to the use of ketene dithioacetals substituted with electron-withdrawing groups. Aiming for the systematic investigation of possible steric and electronic influences on the outcome of the reaction, various combinations of electrophiles and nucleophiles were used and the results of the reactions were compared based on the type of the used dithioacetal. The scope of the presented procedure is shown with four additional transformations including the use of additional electrophiles and nucleophiles, the use of a chiral auxiliary and subsequent reduction of selected products. Additionally, we extended the reaction to the synthesis of diene dithiolanes by addition of an ynone to α-alkyl or aryl-substitued dithiolanylium TFBs.

Las vistas aéreas de Alfred Guesdon constituyen un motivo de recurrente interés por su gran belleza y fiel reflejo de importantes ciudades de la época, así como por los interrogantes que plantea su elaboración. Tras reseñar algunas vistas aéreas dibujadas a mediados del XIX, se revisan las hipótesis sin documentar sobre la relación de Clifford con las vistas españolas de Guesdon y sobre la problemática de su construcción gráfica con la ayuda de planos, fotografías o globos aerostáticos. Sobre ello arroja luz el análisis del inédito dibujo de Córdoba (1853), cuya precisión se constata al compararlo con el coetáneo plano de Montis (1851). En un recorrido por la ciudad dibujada y sus principales hitos se corrobora el valor documental de esta imagen de Guesdon, que supo integrar el dibujo tradicional con los avances técnicos del momento.

A New XRD Method to Quantitatively Distinguish Non-Stoichiometric Magnetite: Influence of Particle Size and Processing Conditions
Authors: Mohd Yusoff Ahmad Huzaifah , Salimi Midhat Nabil Ahmad , Jamlos Mohd Faizal
Published: February 2018

Magnetite’s abilities rely on the quantitative phases present in the sample. Magnetite quality can strongly influence several physical properties, such as magnetism, catalytic performance, and Verwey transition. However, differentiation of magnetite and maghemite through the conventional X-ray diffractogram comparison are not relevant for the intermediate phases. In this study, the deviation from the ideal stoichiometric magnetite and the relative quantification of both phases were mathematically achievable through a new XRD technique. Various synthesis conditions were applied to obtain different crystallite sizes, in the range of 9 to 30 nm. Generally, the stoichiometric deviation and maghemite content would be significantly influenced by the final size, whereas system conditions (temperature of solution, agitation rate, and pH of solution) would only have minor significance. In this study, iron oxide nanoparticles prepared using the co-precipitation method was calculated to contain 100% magnetite for particles of 30.26 nm in size, while 100% maghemite was calculated for particles at 9.64 nm.
Obtaining Ultra-High Surface Area TiO2 Nanorods via Hydrothermally Transformation of Elongated Titanate Nanotubes
Authors: Yuan Song Dong , Chen Shi Qiang , Zhu Xing , Xiong Peng , Yang Yan Fei , Hu Zhi Hai , Xiong Jian
Published: February 2018

In this paper, a tunable TiO2nanorod cross-link structure with ultra-high surface area (up to 109.81 m2/g) has been successfully prepared via hydrothermally treating elongated sodium titanate nanotubes. XRD, SEM, HRTEM and BET analysis were employed to characterize the morphology and inner structure of the samples. The preparation conditions (the hydrothermal temperatures and the pH values of the solutions) of the obtained TiO2products were systematically studied. The maximum length of nanorod reaches to 1 μm while the lateral size could be limited less than 10 nm. The surface area can be easily tuned by modifying the stirring rate during the hydrothermal process. In addition, the photocatalytic performance of synthesized TiO2nanorods were also measured, and the nanorod structure with ultra-high surface area showed much better photocatalytic activity than the sample produced without stirring process, which can be attributed to the influence of the large difference in specific surface area of the obtained TiO2products.
Groundwater-surface water interactions: who cares and why?
Authors: Hinton M J , Russell H A J
Published: February 2018

Groundwater and surface water have different characteristics. They are both part of the hydrologic cycle and there are various hydrologic transfers between them. These hydrological processes also influence biogeochemical and biological processes.
Groundwater-surface water (GW-SW) interactions are the combination of these processes and their effects. GW-SW interactions generally occur at small scales and are spatially and temporally variable but they can influence flow, chemistry and biology at large scales. Therefore, GW-SW interactions
affect many environmental and societal issues related to water quantity, water quality, aquatic ecosystems and watershed management. Science can support management of these issues by determining where and when GW-SW interactions are significant, and what impact they have at larger scales. Partners
in the southern Ontario project of the Groundwater Geoscience Program are working to better understand and characterize GW-SW interactions in Southern Ontario through integrated GW-SW modelling, GW-SW interaction framework development and aerial thermal infra-red reconnaissance
surveys.
From one aquifer-scale mapping to Canada-wide groundwater assessment and accounting: a paradigm shift of scales and tools
Authors: Rivera A
Published: February 2018

Maps are central to our sciences; however, after more than fifteen years of aquifer-scale mapping with hundreds of aquifer maps in store, we still do not have a full portrayal of Canada in terms of the groundwater and aquifers of our country.
Over the years we have learned many interesting lessons with our mapping of aquifers and groundwater assessments. These are very valuable lessons, which can be used to move from one aquifer-scale mapping to Canada-wide groundwater assessment and accounting. This very brief presentation intends to
provide an update of where we are and where we are heading to by describing a paradigm shift of scales and tools in a new and innovative approach to groundwater assessment and accounting.

Hepatic involvement in granulomatosis with polyangiitis – diagnostic difficulties
Authors: Masiak Anna , Drobińska Anna , Zdrojewski Zbigniew
Published: February 2018

We report the case of a 57-year-old Caucasian man who presented with dry cough, haemoptysis, fever, lung nodules, erythrocyturia, and acute hepatitis. After a lung biopsy, the patient was diagnosed with granulomatosis with polyangiitis. The diagnosis was supported by the presence of antiproteinase-3 anti-neutrophil cytoplasmic antibodies. The most common causes of liver damage are excluded.

The patient was treated with prednisone and cyclophosphamide, which resulted in remission of chest CT findings and improvement in liver function tests. During the flare, new lung infiltrations as well as elevation of liver enzymes were present. Treatment with rituximab resulted in complete clinical and radiological remission and normalisation of liver function tests. What makes this case worth reporting is the rare liver involvement in the GPA. After exclusion of coexistence of autoimmune liver disease and drug-induced liver lesion, organ involvement was supported by the reversion of abnormal LFT after the immunosuppression of GPA.

Abstract. The 11-year solar cycle forcing is recognised as a potentially important atmospheric forcing; however, there remain uncertainties in characterising the effects of the solar variability on the atmosphere from observations and models. Here we present the first detailed assessment of the atmospheric response to the 11-year solar cycle in the UM-UKCA chemistry-climate model using an ensemble of integrations over the recent past. Comparison of the model simulations is made with observations and reanalysis. Importantly, in contrast to the majority of previous studies of the solar cycle impacts, we pay particular attention to the role of detection method by comparing the results diagnosed using both a composite and a multiple linear regression method. We show that stratospheric solar responses diagnosed using both techniques largely agree with each other within the associated uncertainties; however, the results show that apparently different signals can be identified by the methods in the troposphere and in the tropical lower stratosphere. Lastly, we focus on the role of internal atmospheric variability on the detection of the 11-year solar responses by comparing the results diagnosed from individual model ensemble members (as opposed to those diagnosed from the full ensemble). We show overall agreement between the ensemble members in the tropical and mid-latitude mid-stratosphere-to-lower-mesosphere, but larger apparent differences at NH high latitudes during the dynamically active season. Our results highlight the need for long data sets for confident detection of solar cycle impacts in the atmosphere, as well as for more research on possible interdependence of the solar cycle forcing with other atmospheric forcings and processes (e.g. QBO, ENSO… etc.).

Published: February 2018

In Iranian educational system, there are special schools offering specialized curriculum for gifted students. In the curriculum of their first degree high school course, complementary contents have been provided in order to improve the process of learning. The objective of the present study has been to evaluate the content of such books which has played a pivotal role in educational process of Iranian gifted schools. We employed the triangulation method. The project was implemented between September 2014 to September 2015 by interviews and researcher-based questionnaires provided by principals, assistant principals, consultants and teachers of middle schools from gifted schools of the Isfahan province of Iran. The reliability coefficient of the questionnaire was 0.88 based on Cronbach's alpha. In order to analyze the qualitative and quantitative data, categorical analysis and descriptive statistics have been applied, respectively.Our questionnaire results showed that the four evaluated complimentary books were in quite desirable status. Based on the findings from the interviews and evidences from the gifted education literature we suggest principles by which selection and revision of complementary contents can be possible. Such principles are as follows: (i) content deepening, (ii) integrative and interdisciplinary organization, (iii) to be problem-oriented, (iv) understanding daily life use of the knowledge and (v) classification of exercises based on their complexity level.
A multiplicidade das novas abordagens sobre uma educação escolar emancipatória no âmbito da Sociologia da Educação
Authors: Lessa Rodrigo
Published: February 2018

Este estudo tem por objetivo análise de algumas vertentes da produção sociológica sobre educação que se esboçou em países como Inglaterra, França e Estados Unidos. Partindo de diferentes perspectivas, autores como Michael Young, Basil Bernstein, Pierre Bourdieu, Michael Apple e Henry Giroux impulsionaram as reflexões deste campo ao enfrentarem questões as relações entre linguagem, ensino e conhecimento no processo educacional e a importância de uma concepção crítica e emancipatória da formação escolar, estabelecendo um novo parâmetro para as reflexões já esboçadas no âmbito da teoria sociológica clássica sobre a educação. Apesar da dificuldade na formulação de novas categorias gerada pelo recorte macrossociológico, esta produção teve a qualidade de fomentar criticamente discussões sobre a aplicabilidade das diversas matrizes da teoria social que inspiraram as reflexões sobre os processos educacionais a partir da segunda metade do século XX.

Published: February 2018

The study focused on the Palestinian state as depicted in the Israeli political discourse. It showed that the Israeli strategy is based on denying the establishment of a Palestinian state alongside the Israeli one. Israel's main concern is to protect its national security at all costs. The study showed the Israeli political factions' opposition to the formation of an independent Palestinian state in addition to their refusal to give up certain parts of the West Bank due to religious and geopolitical reasons. To discuss this topic and achieve the required results, the analytical descriptive approach is adopted by the researcher. The study concluded that the Israeli leadership and its projects to solve the Palestinian issue do not amount to the establishment of a Palestinian state. This leadership simply aims to impress the international public opinion that Israel wants peace. In contrast, the Israeli public has shown that it cannot accept a Palestinian state, and the public opinion of the Palestinian state is not different from that of the political parties and leaders in Israel.
