Purpose: Wildlife resources constitute indispensable nature’s strongholds for human livelihoods strategies in forest, savanna zones across Ghana and the worldwide although, it often engendered conflicts. Impact of community participation on adaptive wildlife resources management was strategically assessed at Mole National Park. Research methodology: 60 randomly selected park environs residents were interviewed for valid responses using semi-structured questionnaires. Findings: High wildlife products demand has transformed bush meat into lucrative business through poaching by thousands of youths and adults, causing habitat destruction and sharp wildlife population decline. Hunters, poachers, middlemen, restaurant operators constituted game-trade-market-value chain. Limitations: Funding subjectivity reduced scope of the study to only few communities in dry season. Temptation to reject the questionnaires on suspicion of force evacuation plots against some park adjoining villages was later refuted. Hence, recovery rate was 100%. Contribution: We recommend that Wildlife Division of the Forestry Commission should strengthen synergies on community participation in adaptive wildlife management by coopting educational interventions that positively influence indigenous behaviors through seminars, workshops, face-to-face interactions. This will better define the rights, roles, responsibilities of key partners towards resolving communal wildlife conflicts. Keywords: Community participation, Wildlife management, Park sustainability, Poaching, Game-trade-market-value chain
EFEKTIFITAS TERAPI ANTI PROGRAMMED DEATH-1 LIGAND (PD-L1) PADA MENINGIOMA
Authors: Janah Raudatul
Published: November 2020

Meningioma adalah tumor intrakranial jinak yang paling banyak ditemukan yaitu terhitung sebanyak 13-26% dari semua tumor intrakranial primer. Pada meningioma yang agresif, ukurannya besar dan tidak dapat dijangkau dengan reseksi bedah, radiasi dan kemoterapi maka dipikirkan terapi alternative lain yaitu dengan menggunakan anti PD-L1. Programmed death-1 ligand (PD-L1) diekspresikan pada tumor dengan derajat yang lebih tinggi berkaitan secara signifikan dengan peran biologi meningioma yang agresif. Imunoterapi menggunakan anti PD-L1 sedang dikembangkan pada pasien-pasien meningioma. Penggunaan imunoterapi (anti PD-1/anti PD-L1) ini dapat menurunkan ukuran tumor pada meningioma. Artikel ini menengulas literature dari WHO, Pubmed, PMC/NCBI, Springer/BMC, Imedpub, Frontier yang berhubungan dari tahun 2001 hingga tahun 2018. Pengobatan meningioma dengan imunoterapi anti PD-L1 (Nivolumab) menunjukkan hasil yang signifikan yaitu menurunkan ukuran tumor. Pada masa depan terapi kombinasi harus dipilih selaras dengan keadaan pasien berkaitan dengan keadaan klinis yang saat ini belum terpenuhi.

Authors: Moss David
Published: November 2020

e review recent work on narrowband orthogonally polarized optical RF single sideband generators as well as dual-channel equalization, both based on high-Q integrated ring resonators. The devices operate in the optical telecommunications C-band and enable RF operation over a range of either fixed or thermally tuneable frequencies. They operate via TE/TM mode birefringence in the resonator. We achieve a very large dynamic tuning range of over 55 dB for both the optical carrier-to-sideband ratio and the dual-channel RF equalization for both the fixed and tunable devices.

This study aims to dynamically analyze blasting conducted in the Nanjung tunnel. Nanjung Tunnel is a twin tunnel that has a horseshoe-shaped section with each tunnel having a dimension of 10.2 m x 9.2 m, and 230 meters in length. The layers rock of this tunnel include silty clay, sandstone and dacite. Blasting was carried out on one of the tunnels consisting of dacite rock, having a 75-90% RQD and UCS 49-61 MPa. During the blast, PPV measurements were taken at several points around the tunnel using a minimate.Dynamic analysis is done by building a Nanjung Tunnel model on the RS2 software with the finite element method. Input data in this modeling is endeavored to approach actual conditions in the field, such as tunnel geometry, rock mass properties, and blasting plans carried out at STA 30-32 tunnels 2. This modeling is expected to produce PPV that is close to actual PPV and the results of this model will be continued to the stability analysis tunnel 1.Modeling results indicate that the tunnel 1 condition is stable during blasting. The stability of tunnel 1 based on smallest strength factor on the roof is around 2.6. Stability also seen from the strain level in dacite and sandstone rocks which are 0.07% and 0.38%. These strain levels are still permissible according to the Sakurai strain level diagram, 1983.

ABSTRAKPembakaran spontan batubara dapat menjadi masalah yang serius terutama bagi kegiatan penambangan karena dapat menyebabkan terjadinya kebakaran pada penimbunan batubara atau ledakan gas metana pada tambang bawah tanah batubara. Penelitian kali ini akan dititikberatkan pada pengaruh ukuran butir batubara dan tingkat kepadatan batubara terhadap perilaku pembakaran spontan batubara. Ukuran butir yang digunakan dengan penelitian ini adalah -10+14 mesh, -60+80 mesh dan -170+200 mesh dengan tingkat kepadatan 0 kPa dan 50 kPa. Ukuran butir ini dipilih untuk mewakili kondisi ukuran butir relatif besar hingga kecil pada penimbunan batubara, sedangkan tingkat kepadatan diasumsikan berasal dari ground pressure dozer sebesar 50 kPa. Dalam penelitian kali ini, digunakan metode oksidasi adiabatik dengan mengalirkan gas oksigen dengan debit 0,05 L/menit pada tabung uji. Selain itu, dilakukan pula pengujian difusi oksigen untuk menentukan laju kenaikan konsentrasi oksigen pada masing-masing parameter. Ukuran butir dan tingkat kepadatan butiran batubara memiliki pengaruh besar terhadap terjadinya pembakaran spontan batubara. Semakin kecil ukuran percontoh maka nilai R70 semakin besar. Adanya pemadatan memiliki pengaruh yang berbeda terhadap nilai R70 pada ukuran butir yang berbeda. ABSTRACTSpontaneous combustion of coal can be a serious problem especially for mining activities because it can cause fires in coal stockpiling or methane gas explosions in coal underground mines. This research will focus on the influence of coal grain size and coal compaction on the spontaneous combustion behavior of coal. The grain sizes used in this study are -10 + 14 mesh, -60 + 80 mesh and -170 + 200 mesh with a compaction pressure of 0 kPa and 50 kPa. This grain size was chosen to represent the condition from large to small grain size in coal stockpile, while the compaction level is assumed to come from the dozer ground pressure of 50 kPa. In this study, an adiabatic oxidation method was used by flowing oxygen gas with a discharge of 0.05 L / min in the test tube. In addition, an oxygen diffusion test was also carried out to determine the rate of oxygen concentration increase for each parameter. Grain size and compaction level of coal grains have a major influence on the spontaneous combustion of coal. The smaller the sample size, the greater the R70 value. The presence of compaction has a different effect on the value of R70 at different grain sizes.

Published: November 2020

Sixty-eight pepper (Capsicum chinense Jacq.) accessions were evaluated for yield (measured as total number of fruits per plant and total fruit weight per plant) and 15 other traits under open-field conditions in two trials, one conducted in the dry (Trial-1) and the other in wet season (Trial-2) of 2014. Each trial was set in a randomized complete block design with three replications (20 plants per replicate) at The University of the West Indies Field Station, Mount Hope, Trinidad and Tobago. There were significant differences (p < 0.01 to 0.001) among the accessions for all traits except plant height, plant canopy width in Trial-1, and early vigour in Trial-2. Total number of fruits per plants was weakly correlated (r = 0.37 in Trial-1, r = 0.45 in Trial-2; p < 0.01 to 0.001) with total fruit weight per plant, but was strongly associated with number of fruits per plant in the first and second 5 pickings (r = 0.78 to 0.97, p < 0.001) and moderately negatively correlated (r = -0.33 to -0.56, p < 0.01 to 0.001) with fruit width and average fruit weight. Total fruit weight per plant was positively associated with fruit weight per plant in the first and second 5 pickings (r = 0.66 to 0.89, p < 0.001), and negatively correlated (r = -0.41 to -0.69, p < 0.001) with days to 50% flowering and fruiting. A comparison of linear regression lines showed that the relative ranking of the accessions over seasons did not change for days to 50% flowering and fruiting, fruit weight per plant in the second 5 pickings, total fruit weight per plant and fruit width. The implications of these results are discussed.

Published: November 2020

When photovoltaic stations operate, providing large populated areas of the planet, and generating significant amounts of electrical energy, problems often arise due to the inconstancy of the flux of incident solar radiation. This leads to failures in the operation of electrical networks and rapid wear of equipment. By equipping such facilities with new systems for the control and monitoring of photovoltaic parameters, it is possible to significantly increase the generation of electrical energy supplied to the general or local power system, and improve the efficiency of the electrical installations located at the solar power plant. The proposed work presents a general approach to modeling and controlling the operation of photovoltaic systems (PV systems). The necessary data for modeling are provided by manufacturers in the form of tables. The processing of this data provides experimenters and engineers with a convenient way to investigate the problems of integrating photovoltaic systems into uninterruptible generation installations to supply individual consumers. The two-stage power conversion system (PCS) proposed in this article works in conjunction with a photovoltaic generating system. The electrical energy storage system (BESS system) uses rechargeable batteries and can be connected to the DC circuit by means of a bidirectional converter. Thus, the BESS system may provide some auxiliary services that may be needed to improve operational efficiency during the generation process. This article describes a special system of uninterrupted operation (FRT-system), which allows you to create the possibility of uninterrupted operation and the generation of electrical energy by the generation system, in case of incorrect operation of individual nodes (for example, with partial shading of solar modules). The operation of an integrated generation system, an electric energy storage system (BESS-system) and a photovoltaic system (PV-system), together with the corresponding control systems simulated on Matlab platforms and the simulation results confirm the efficiency of the controller. When introducing the proposed systems at existing and under construction solar power plants (SPP), it is possible to significantly improve the efficiency of their work and increase the generation of electricity for consumers.
Singular Perturbation Analysis for Identification of Dynamic Behaviour and Stability of a Nonlinear Model of Long Term Progression of Diabetes Mellitus
Authors: Ratanakul Chontita , Lenbury Yongwimon , Suksamran Jeerawan
Published: November 2020

There have been numerous attempts to model the progression of Diabetes Mellitus, which is a disease suffered by those with eating disorders with prevalence in the aged population. Models in the past have not been very successful in discovering the future development of the symptoms in a long term prediction. This is due to the fact that the state variables under consideration change in drastically different time scales, and the models that do not take careful account of this are not able to provide sufficiently accurate forecast that can be of satisfactory assistance to physicians taking care of their patients. In this work, we use the singular perturbation method to analyse a model of insulin and glucose interaction, incorporating beta cell dynamics and the pancreatic reserve, proposed by De Gaetano et al. in 2008. Different dynamic behaviour will be identified and numerical simulations will be carried out in support of our theoretical predictions.
Vaistai, gerinantys bronchų sekreto pasišalinimą sergant cistine fibroze
Authors: Kalinauskaitė-Žukauskė Virginija , Malakauskas Kęstutis
Published: November 2020

Cistinė fibrozė (CF) yra reta, autosominiu recesyviniu būdu paveldima ir dažniausiai plaučius bei virškinimo sistemą pažeidžianti liga. Nepaisant to, kad ir virškinamojo trakto pažaida gali sukelti rimtų sveikatos problemų, paprastai sergančiųjų sunkiau toleruojama didesnė bronchų sekreto produkcija, sunkesnis atsikosėjimas, dusulys, infekcinės ligos paūmėjimai. Pastarieji dažniau lemia ir mirtinas ligos baigtis. Užtikrinus gerą bronchų sekreto evakuaciją galima suretinti CF paūmėjimus, pagerinti sergančiojo gyvenimo kokybę, sulėtinti ligos progresavimą. Vaistų, gerinančių kvėpavimo takų mukociliarinį klirensą, pasirinkimas nėra siauras, tačiau jų veiksmingumas priklauso nuo tiršto bronchų sekreto patofiziologinių ypatumų. Todėl, sergant CF, klinikinėje praktikoje yra patvirtintas tik vienas mukolitikas, efektyviai mažinantis bronchų sekreto klampumą ir elastingumą. Tai įkvepiamoji dornazė alfa (Pulmozyme®) – fosforilinto, glikozilinto rekombinantinio žmogaus baltymo deoksiribonukleazė 1. Vaistas skystina kvėpavimo takų sekretą ardydamas neutrofilų DNR (veiksmingumas ir saugumas yra pagrįstas klinikiniais tyrimais). Kiti bronchų sekreto pasišalinimą gerinantys medikamentai sergant CF yra priskiriami atsikosėjimą gerinantiems vaistams – tai hipertoninis druskos tirpalas ir manitolis. Nors pastarieji turi patvirtintas indikacijas ir gali būti skiriami siekiant suskystinti tirštą bronchų sekretą sergant CF, dėl jų veikimo principo skirtumų yra mažiau efektyvūs už inhaliuojamąją dornazę alfa.
Particle-in-cell Simulation of Whistler Heat-flux Instabilities in the Solar Wind: Heat-flux Regulation and Electron Halo Formation

Published: November 2020

We present results of a two-dimensional fully kinetic particle-in-cell simulation in order to shed light on the role of whistler waves in the scattering of strahl electrons and in the heat-flux regulation in the solar wind. We model the electron velocity distribution function as initially composed of core and strahl populations as typically encountered in the near-Sun solar wind as observed by Parker Solar Probe. We demonstrate that, as a consequence of the evolution of the electron velocity distribution function (VDF), two branches of the whistler heat-flux instability can be excited, which can drive whistler waves propagating in the direction oblique or parallel to the background magnetic field. First, oblique whistler waves induce pitch-angle scattering of strahl electrons, toward higher perpendicular velocities. This leads to the broadening of the strahl pitch-angle distribution and hence to the formation of a halo-like population at the expense of the strahl. Later on, the electron VDF experiences the effect of parallel whistler waves, which contributes to the redistribution of the particles scattered in the perpendicular direction into a more symmetric halo, in agreement with observations. Simulation results show a remarkable agreement with the linear theory of the oblique whistler heat-flux instability. The process is accompanied by a significant decrease of the heat flux carried by the strahl population.

The fish feed used in aquaculture systems has many nutritional factors like protein, fat, fiber, ash, and humidity; from these factors, one of great importance is protein. The protein of fish feed is obtained from fish meal, and the demand for fish meal has increased; this induces to increase the price. Many pieces of research have been done about this topic to mitigate this problem. This research shows the differences between three commercial foods of the different processes with the same quantity of protein, using tilapia Oreochromis niloticus, to prove any difference between NO2-, NO3-, and NH4+. Nitrogen compounds were determined with HACH methods for the DR6000 spectrophotometer. Biometric data were registered throughout the growth of fish, along with measure aerobic metabolism. Results have shown that has better outcomes related to low excretion of nitrogen compound was medium-cost fish feed (MCFF). It also has sound effects associated with the length-weight relationship; that could be connected to these fish feed's protein sources.
Cardiac memory phenomenon, time-fractional order nonlinear system and bidomain-torso type model in electrocardiology
Authors: Belmiloudi Aziz
Published: November 2020

Cardiac memory, also known as the Chatterjee phenomenon, refers to the persistent but reversible T-wave changes on ECG caused by an abnormal electrical activation pattern. After a period of abnormal ventricular activation in which the myocardial repolarization is altered and delayed (such as with artificial pacemakers, tachyarrhythmias with wide QRS complexes or ventricular pre-excitation), the heart remembers and mirrors its repolarization in the direction of the vector of "abnormally" activated QRS complexes. This phenomenon alters patterns of gap junction distribution and generates changes in repolarization seen at the level of ionic-channel, ionic concentrations, ionic-current gating and action potential. In this work, we propose a mathematical model of cardiac electrophysiology which takes into account cardiac memory phenomena. The electrical activity in heart through torso, which is dependent on the prior history of accrued heartbeats, is mathematically modeled by a modified bidomain system with time fractional-order dynamics (which are used to describe processes that exhibit memory). This new bidomain system, that I name "it memory bidomain system", is a degenerate nonlinear coupled system of reaction-diffusion equations in shape of a fractional-order differential equation coupled with a set of time fractional-order partial differential equations. Cardiac memory is represented via fractional-order capacitor (associate to capacitive current) and fractional-order cellular membrane dynamics. First, mathematical model is introduced. Afterward, results on generalized Gronwall inequality within the framework of coupled fractional differential equations are developed. Next, the existence and uniqueness of solution of state system are proved as well as stability result. Further, some preliminary numerical applications are performed to show that memory reproduced by fractional-order derivatives can play a significant role on key dependent electrical properties including APD, action potential morphology and spontaneous activity.

SMM (social media marketing) aims to produce content that users share in their various social media applications in order to increase brand exposure and broaden customer reach. There are numerous marketing techniques to apply in social media in order to involve the customer, some of which have costs and others do not. Digitization was a real challenge for any hotel company, requiring cautious and well-planned action to be successful. In this sense, the nature of social networks demands the adoption of a constructivist perspective, that is, a perspective that involves affirmations of knowledge based on individual and collective experiences. Presently, being present in social networks presents itself as a high value advantage, allowing to expose the brand, product, or idea, at a low cost, to a high audience. This chapter aims to systematize some relational marketing best practices that are identified in the luxury hotel segment in Europe (i.e., communication). Specifically, some examples of relational marketing (hotel/consumer) in terms of communication will be identified and analysed.

The proliferation, differentiation, and survival of cells of the mononuclear phagocyte system (MPS; progenitors, monocytes, macrophages, and classical dendritic cells) are controlled by signals from the M-CSF receptor (CSF1R). Cells of the MPS lineage have been identified using numerous surface markers and transgenic reporters, but none is both universal and lineage restricted. In this article, we report the development and characterization of a CSF1R reporter mouse. A FusionRed (FRed) cassette was inserted in-frame with the C terminus of CSF1R, separated by a T2A-cleavable linker. The insertion had no effect of CSF1R expression or function. CSF1R-FRed was expressed in monocytes and macrophages and absent from granulocytes and lymphocytes. In bone marrow, CSF1R-FRed was absent in lineage-negative hematopoietic stem cells, arguing against a direct role for CSF1R in myeloid lineage commitment. It was highly expressed in marrow monocytes and common myeloid progenitors but significantly lower in granulocyte-macrophage progenitors. In sections of bone marrow, CSF1R-FRed was also detected in osteoclasts, CD169+ resident macrophages, and, consistent with previous mRNA analysis, in megakaryocytes. In lymphoid tissues, CSF1R-FRed highlighted diverse MPS populations, including classical dendritic cells. Whole mount imaging of nonlymphoid tissues in mice with combined CSF1R-FRed/Csf1r-EGFP confirmed the restriction of CSF1R expression to MPS cells. The two markers highlight the remarkable abundance and regular distribution of tissue MPS cells, including novel macrophage populations within tendon and skeletal muscle and underlying the mesothelial/serosal/capsular surfaces of every major organ. The CSF1R-FRed mouse provides a novel reporter with exquisite specificity for cells of the MPS.

Authors: Eya Jonathan C. , Onyekwulu Fidelis A. , Amucheazi Adaobi O. , Ajuzieogu Obinna V.
Published: November 2020

Objective:

To assess the effectiveness of intravenous (iv) paracetamol (PCM) infusion in prolonging the duration of analgesia following spinal anesthesia and to determine patients’ satisfaction with pain relief.

Materials and Methods:

This was a double-blind, randomized, controlled study. A total of 126 adult American Society of Anesthesiologists physical status I or II women scheduled for elective myomectomy under spinal anesthesia were enrolled in the study. Patients were randomly allocated into two groups. PCM group (group A) [n = 63] received 100mL of 1g PCM and Normal saline group (group B) [n = 63] received 100mL of normal saline after spinal anesthesia was established. Statistical analysis was done using Statistical Package for Social Sciences, version 17.

Results:

There was no statistical difference between the groups in terms of age, weight, and body mass index. The mean time to first analgesic demand was 4.75 ± 1.59 h in group A and 2.23 ± 0.15 h in group B (P < 0.001), while the mean dose of additional analgesic was significantly lower in group A (11.81 ± 2.50 µg) when compared to group B (255.49 ± 140.80 µg), P < 0.001. In group A, 75.8% expressed excellent satisfaction with pain relief while 62.9% of patient in group B reported poor satisfaction with pain relief (χ2 = 87.600, P < 0.001).

Conclusion:

Intravenous infusion of 1g PCM is effective in prolonging the duration of analgesia following spinal anesthesia for myomectomy.
Evolution of the Regulation and Character of Municipal Programmes for the Care of Homeless Animals and Animal Homelessness Prevention in Poland
Authors: Spasowska-Czarny Hanna Malgorzata
Published: November 2020

One of the legal forms of action to be applied by a commune for the care of homeless animals is to develop and implement homeless animal care programmes and prevent animal homelessness. The whole regulations examined below clearly demonstrate that the commune carries out its duties as mentioned above, cooperating with registered and legally operating animal shelters. Derogations from this principle may be regarded as the unlawful  fulfilment of commune's own tasks, which is the subject of an audit by the State Veterinary Inspectorate or the voivodeship governor. However, it may be difficult to make a clear identification of the legal nature of homeless animal care programmes and animal homelessness prevention as acts of local law or planning acts as internal law acts. The views of scholars and case-law on this issue are not uniform.
How many Instances in the Polish Administrative Procedure? Analysis of Normative Solutions in the Aspect of Procedures for Reviewing Decisions Issued by the Executive Bodies of Local Self-government
Authors: Michalak Magdalena Maria , Kledzik Przemysław
Published: November 2020

Pursuant to the art. 78 of the Constitution of the Republic of Poland each party has the right to appeal against  judgments and decisions issued in the first instance. The Constitution also stipulates that administrative courts control the activity of administration in at least two-tier proceedings. Pursuant to the above, in Poland, decisions are issued in two-tier general administrative proceedings and may be subject to review in two-tier court administrative proceedings. The number and structure of procedures of appeal against administrative decisions have been a subject of discussion for years. Criticism of the current solution comes, among others, from local self-government representatives whose bodies issue the largest number of decisions in Poland. These issues have recently become even more relevant due to statutory obligation of reviewing Polish legislation in terms of legitimacy of reducing the number of administrative instances. The subject of the study is an analysis of possibility and purposefulness of limiting the number of instances in the administrative procedure, conducted on the example of a procedure for reviewing decisions of local self-government bodies. The reflection was made taking into account systemic and procedural position of Self-Government Boards of Appeal.
Diplomacy and the karczma/taberna: The role of Cracovian public houses in the diplomatic practice of the Jagiellonians (1430–1540)
Authors: Dobek Peter
Published: November 2020

Public houses – inns, taverns, and alehouses – during the Jagiellonian Dynasty (1385–1572) in Cracow functioned as important establishments in the diplomatic services of kings, city officials, and the nobility. Not only did these locales offer drink, food, and accommodations to emissaries for their travels and work, but they provided much more. For the diplomats, the inns, taverns, and alehouses were sites to learn the latest news, gossip, and public opinion. They provided a place to fraternize and they were also trusted locations for sensitive diplomatic negotiations. Public houses likewise served as “post offices” where envoys could receive their letters. Although scholars have studied these establishments, the diplomacy, and urban history throughout Europe in various epochs, they have neglected to analyze the role of the Cracovian public houses in diplomatic services in the Jagiellonian era. This article provides a comprehensive examination of sources, including royal and municipal accounting and personal correspondence, to reveal the role of public houses in the diplomatic practices of the Jagiellonian dynasty.
Towarzystwo Gimnastyczne „Sokół” w Tarnowie i gniazda okręgu tarnowskiego do 1919 roku

“Sokół” Gymnastic Society in Tarnów and Tarnów district before 1919 In 1867, the first “Sokół” Gymnastic Society in the Polish land was established in Lviv. In 1884, its first branches were registered in Tarnów and Stanisławów. In 1892, dozens of “nests” already existed in Galicia, and it was decided to combine them into the Union of Polish “Sokół” Gymnastic Societies in Austria (Związek Polskich Gimnastycznych Towarzystw Sokolich w Austrii). In 1895, there were already 70 societies in the country, so districts were created which served as a link between the “nests” and the Association. There were seven districts, with their headquarters in Kraków, Tarnów, Rzeszów, Przemyśl, Lwów, Tarnopol and Stanisławów, respectively. In the following article, the author presents the history of the “nests” of the Second District of Tarnów from the creation of the Tarnów society to the incorporation of the Galician “Sokół” Association into the new Association of the “Sokół” Gymnastic Societies in Poland in 1919.
Dział majątku subdelegata grodzkiego radomskiego Stanisława Rakowskiego z 1786 roku
Authors: Kozdrach Mariusz
Published: November 2020

The 1786 estate settlement of Stanisław Rakowski, a castle court official of Radom Stanisław Rakowski (d. post-1786), was one of the many anonymous representatives of the Polish judicature of the 18th c. Politically uninvolved, he spent a few decades in Radom, where he worked and lived as a member of the town’s elite (he never owned any land). In 1785 he transmitted his several-thousand property, gathered over the years, to his children: a son (rev. Ignacy) and two daughters (married to noblemen from lawyers families). The document, being an effect of the agreement between Rakowski’s successors, is the object of the present study. The estate settlement, preserved in the 19th-century mortgage book, belongs to the sparse descriptive sources on the pre-partition Radom and the material culture of its elite, as the basic sources on the Old-Polish Sandomierz Voivodeship had been destroyed during WWII. Above all, the act is a valuable relic of the Old-Polish law, presenting the manner of dividing property among the landless nobility (impossessionati): a problem slightly examined in Polish historiography.
