Conclusão Esta revisão sistemática revelou que as principais consequências dos acidentes de trânsito para as vítimas não fatais estão nas estruturas do corpo relacionadas ao movimento e à mobilidade e estabilidade das articulações.
“Of Course, You Know Her!” (Pl. Phd. 60a). Xanthippe’s Presence by Socrates Deathbed
Authors: Guimarães Leonardo , Pio Fernanda , Cornelli Gabriele
Published: May 2024

In Plato's Phaedo, when arriving to visit Socrates on his last day in prison, his friends and companions meet his wife, Xanthippe. This is the only time she is directly mentioned in the Platonic dialogues. The present paper aims to investigate the character of Xanthippe by going through the doxographic reception of the figure of Socrate's wife, a necessary path to reveal the social representation of the role of woman and wife entrenched in these views. Next, we will investigate the way the character Xanthippe is represented on the Platonic stage, in search of traces of a different representation of gender in the Platonic pages. One in which the figure of the woman, wife and mother Xanthippe is there to challenge Socrates and his philosophy.

Este artigo se propôs a construir coletivamente com a comunidade da Ilha de Maré, localizada em Salvador, Bahia, Brasil; um texto-território-denúncia sobre a necropolítica ambiental e a resistência da comunidade. O projeto Ilha dos Abraços, parte do projeto guarda-chuva Planet&Ar, se propôs trabalhar vigilância popular através de uma residência artística com um grupo transdisciplinar de artistas, profissionais da saúde e urbanistas para realizar um mapa de memórias com as histórias da comunidade e painéis de grafite que se comunicassem em um “livro navegável”. A residência artística aconteceu entre 11-20/11/2022 com a realização de oficinas de quadrinhos, grafite, saúde planetária, sete painéis de grafite e entrevistas para a composição do mapa de memórias. Há a necessidade de saber pisar no território para adentrar uma comunidade quilombola e a percepção não apenas da tradição oral da Ilha de Maré, mas também a da escuta, e se propõe o termo “escutação”. Reflete-se também sobre a invisibilização da ilha frente à poluição e aos poderes públicos, de forma que a arte transgride este silenciamento. Assim, saúde planetária pode ser uma aliada  para a luta da comunidade, porém questiona-se o conceito universalizante, propondo-se a ideia de saúde(s) planetária(s).
PERCEPCIONES COMUNITARIAS SOBRE EVENTOS ADVERSOS EN LA LAGUNITA-SUCRE (VENEZUELA)
Authors: Rosales-Veítia José , Montilla Arismar Marcano
Published: May 2024

En las últimas décadas se ha dado un crecimiento acelerado de comunidades urbanas no planificadas en Venezuela, motivado por factores asociados al éxodo rural iniciado a mediados de siglo pasado, construyendo espacios de riesgos que han sido afectados ante la ocurrencia de eventos adversos, por lo cual se requiere conocer las representaciones sociales de sus afectados. Por tal motivo, la investigación tuvo como propósito interpretar las representaciones sociales de los habitantes de la comunidad La Lagunita-Sucre, acerca de los eventos adversos ocurridos en ella. Se trató de un estudio interpretativo, en el que se hizo uso del método hermenéutico para alcanzar los hallazgos. Para su desarrollo se escogieron a través de un muestreo basado en criterios a diez informantes clave a quienes se les aplicó una entrevista en profundidad. Los hallazgos del estudio se organizaron en tres categorías emergentes: a) La Lagunita-Sucre… entre el alba y el terremoto; b) Movimientos de remoción en masa, parte de la historia comunitaria; c) Una comunidad, un espacio multiamenaza. La interpretación permitió comprender que es fundamental la promoción de la conciencia sobre los escenarios de riesgo y educar a la comunidad para prepararse y mitigar los efectos de los desastres.
EFFECTIVE STIFFNESS TENSOR OF COMPOSITE MATERIALS WITH INCLUSIONS OF RANDOM SIZE AND PERIODIC LOCATION OF THEIR CENTERS
Authors: Vlasov Alexander N. , Vlasov D. A. , Sorokin G. S. , Karnet Yulia N.
Published: May 2024

In this study, we investigated the possibility of determining the stiffness tensor using theoretical methods.
We utilized a periodicity cell, not a representative elementary volume, to solve the problem, in
which the periodicity of the inclusion center locations was considered. Three options were employed
to estimate the effective deformation properties of composite materials with periodic inclusion center
location arrangements and random size values. In this paper, the applicability of the proposed probabilistic
approach to determining the effective stiffness tensor on a periodicity cell is shown. This approach
allows one to obtain not only the mean values (i.e., the effective stiffness tensor) but also three main
central moments-from the second to the fourth order-characterizing the random nature of the effective stiffness tensor. The approach developed and employed in this study to estimate the effective deformation
characteristics of composite materials with periodic inclusion center location arrangements,
characterized by random radii values, could be practically extended to other physical and mechanical properties.

Authors: Carvalho de Vasconcelos Raphael , De Moura Tebaldi Bernardo
Published: May 2024

A finalidade do presente estudo é identificar o panorama histórico e a posição atual do debate acerca da implementação de uma moeda de uso regional entre o Brasil e a Argentina. Essa pesquisa foi motivada pela proposta de adoção de uma moeda regional para uso nas transações comerciais bilaterais, por ocasião da viagem oficial do atual mandatário brasileiro à Argentina, em 23 de janeiro de 2023. A ideia de adoção de uma moeda regional, inclusive, ventilada entre esses dois países, não é recente e chegou a ser considerada no âmbito do Mercosul. Para o presente estudo foram utilizados como base da pesquisa a análise de indicadores econômicos, textos acadêmicos e, sobretudo, reportagens jornalísticas, atas de reuniões e a própria norma do Mercosul. Dessa forma, foi possível entender como a proposta mudou ao longo dos anos e em qual contexto isso ocorreu. Esse estudo possui três momentos distintos, o primeiro deles focado nas possíveis vantagens e desvantagens, bem como nos impactos nos custos de transação com a adoção de alternativas monetárias no comércio bilateral, além de prover a conceituação terminológica necessária. Em um segundo momento centrou-se na evolução histórica da proposta de adoção de uma moeda regional para que, em um terceiro momento fosse possível focar na proposta atual em si.
SPONTANEOUS RUPTURE OF URINARY BLADDER
Authors: Yarovoy Sergey , Asfandiarov Faik , Kruglov Vladimir , Seidov Kaflan , Lyashenko Vladimir , Derevyanko Tat'yana
Published: May 2024

: Bladder ruptures are a serious injury to the abdomen and pelvis. The development of urinary
leaks, peritonitis and septic complications cause a high mortality rate in this pathology. In the vast majority of
cases, the cause of bladder rupture is trauma. Much less common are the so-called spontaneous ruptures of the
bladder, in which the main cause is weakness of the muscle wall, against which a minimal increase in
intravesical pressure leads to rupture of the organ according to a typical hydrodynamic mechanism. The rarity
of this pathology, the variety of etiological factors, and the absence of any specific clinical manifestations in
most cases lead to delayed diagnosis, which negatively affects the results of treatment. This paper summarizes
the literature data and our own clinical experience in treating patients with spontaneous rupture of the bladder.
The above analysis of clinical observations will allow practicing urological surgeons to be more attentive and
purposeful in collecting anamnesis in patients with a clinical picture of an acute abdomen and, if there is a
suspicion of spontaneous rupture of the bladder, to use a set of modern diagnostic capabilities. An accurate
and timely diagnosis will allow patients to be operated on earlier, before the clinical manifestations of diffuse
peritonitis develop, which will have a positive impact on the results of treatment.

Seasonality as Factor of Logistic Costs Formation
Authors: Kazarina Larisa
Published: May 2024

The seasonality of demand for goods and services creates vital issues both for the organization of their production, and for implementation of logistic processes. Seasonal fluctuations, as a rule, negatively affect work of the enterprises that is shown in equipment downtimes, incomplete use production and warehouse, in uneven use of human resources, violation of rhythm of activity, to the unreasonable growth of costs. In logistic activity the seasonality influences a set of its components, including creation and maintenance of stocks, existence of warehouse spaces, number and capacities of sales channels and supply. This influence in much defines fluctuations of values of logistic costs. The article proposes an approach to identifying the presence of seasonality, quantitative characteristics in various periods of the annual cycle, the separation of seasonal and trend components of seasonality dynamics, mathematical and statistical modeling of seasonality in the formation of such costs. A forecast assessment of the future dynamics of costs is carried out. Emphasis is made on the highlighting the seasonal component in the indicators of logistics costs that allows to analyze their dynamics more deeply, improve the quality of management decisions associated with them.

Проанализированы географические особенности дифференциации почв и почвенного покрова на участках произрастания лесополос в агролесомелиоративных ландшафтах юга Среднерусской возвышенности. Обсуждается роль лесополос в депонировании органического углерода почв. Высказано предположение о важном факторе отмирания старовозрастных древостоев в пополнении почв лесополос гумусом. На ряде примеров обоснована важная функция лесополос как механических и биогеохимических барьеров. Аргументируется формирование линейно ориентированных полосчатых микроструктур почвенного покрова или почвенно-экологических зон. Их возникновение обусловлено специфичностью развития почвообразовательных процессов при формировании лесополос (в результате пространственной дифференциации микроклиматических условий), а также особенностями технологий обработки почв и других приемов агротехники в краевых частях полей рядом с лесополосами.

Традиционные климатические показатели и связанные с ними коэффициенты и индексы не дают должного представления о реакции ландшафтов на происходящие климатические изменения. Посредством ландшафтного подхода авторами дана оценка временной структуры степных ландшафтов Северного Кавказа. Выявлены группы состояний благоприятно сказывающихся на урожайности сельскохозяйственных культур, а также состояния, которые негативно воздействуют на агроландшафты. Показано, что засухи в степных ландшафтах встречаются намного чаще, чем криотермальные состояния, приводящие к повреждению сельскохозяйственных всходов зимой.

Konut ve kiralama piyasası ülke ekonomilerinde önemli bir ekonomik yere sahiptir. Konut fiyatları genel olarak evin alanı, oda sayısı, bulunduğu kat gibi özelliklere göre belirlenmektedir. Ancak evin bu özelliklerinin yanı sıra konumu da evin pazarlama değerlendirmesi üzerinde önemli bir etkiye sahiptir. Bu bakımdan subjektif fiyat spekülasyonlarının önüne geçebilmek için, konutun konumunu objektif kriterlere göre değerlendirebilmek oldukça önemlidir.

Bu çalışmada bir nesnenin konumunun değerlendirilmesi, çok kriterli karar verme problemi olarak ele alınmıştır. Bu konumdan toplu taşıma araçlarıyla şehrin diğer noktalarına ulaşım kolaylığının yanı sıra metro istasyonları, hastaneler, alışveriş merkezleri, yeşil park alanları gibi önemli noktalara ulaşımın kolaylığını da göz önünde bulundurmaktadır. Bu bağlamda, bir toplu taşıma ağı (TTA) mesafe kavramı tanıtılmış ve Konum Değerlendirme Endeksi (KDE) adı verilen bir endeks önerilmiştir. Konutun konumuna göre piyasa değerinin tahmin edilmesinde bu endeksin önemi vurgulanmıştır. Önerilen model, Türkiye'nin üçüncü büyük metropol şehri olan İzmir şehrinin toplu ulaşım ağı verileri üzerinde çalıştırılmış ve şehrin KDE ısı haritası oluşturulmuştur.
PVA/Na-Bentonite kompozitlerin yapısal ve dielektrik özelliklerinin incelenmesi
Authors: Akar Yeşim , Kaya Ahmet Uğur
Published: May 2024

Bu çalışmada Polivinilalkol (PVA)/Na-Bentonit kompozitleri hazırlanmıştır. Kompozitlerin hazırlanmasında kilin içerisine kütlece maksimum %13 oranında polimer yüklenmiştir. Çözelti karıştırma tekniği ile hazırlanan kompozitlerin yapısal özellikleri X-ışını floresans spektrometresi (XRF), Fourier Dönüşümlü kızılötesi spektrometresi (FTIR) ve X-ışını kırınımı (XRD) teknikleri kullanılarak incelenmiştir. Dielektrik özellikler Dielektrik spektroskopi (DS) yardımıyla belirlendi. XRF çalışmasından, kil orijininin Yunanistan'ın milos adasında Asbro-Horio rezervuarından sağlanan Kalsiyum bentonit (Ca-Bentonite) olduğu ve Tedarikçi (Imerys-Türkiye) tarafından kili sodyum zenginleştirme işlemi ile Na-Bentonite dönüştürdüğü anlaşılmıştır. XRD ve FTIR ölçümlerinden PVA'nın Na-bentonit galerileri arasında yer almak yerine Na-Bentonit yüzeyi ile etkileşime girdiği gözlenmiştir. Polimer ve kil arasındaki bu etkileşim, hem polimer zincirlerinin segmental hareketini hem de kil yüzeyindeki hidroksil gruplarının yönelimini sınırlamıştır. Düşük frekans bölgesinde, kompozitlerin dielektrik sabiti (reel kısım) özellikle düşük PVA katkı oranlarında Na-Bentonite göre önemli ölçüde azalmıştır. Elektrot polarizasyon etkisi düşük katkılı kompozitlerde oldukça azalmıştır.

A brief analysis of the causes of inhomogeneous and unstable current distribution between elementary transistors in comb structures (CS) of bipolar (BT) and heterobipolar (HBT) microwave transistors is presented. An expression for the current flowing into a CS elementary transistor, taking into account the emitter track metallization resistance, is derived. An estimation of the influence of technological variation of emitter metallization track resistances on the non-uniformity of the transistor total current distribution between elementary transistors is given. It is shown that resistance of emitter tracks of metallization plays a stabilizing role and leads to increase of thermal stability of current distribution in CS, thus the least stable to thermal breakdown will be elementary transistor of CS with the least resistance of emitter track and the greatest thermal resistance. Recommendations on equalization and increase of stability of current distribution in CS of BT and HBT are offered.

In this work, the total acoustic wave losses in 128°Y-LiNbO3 wafers during liquid application due to radiation emission of waves into the liquid medium, as well as its viscosity, conductivity, density and dielectric constant of the liquid analyte are measured. Solutions with 5 basic flavors, widely used for calibration and reference creation in liquid media testing, were selected as test liquids. The measurements were performed in the range of 30...60 MHz. After the measurements, the experimental data were presented in the form of polar histograms, from the comparison of areas and shapes of which the flavor of a particular liquid was determined. Then, a principal component analysis (PCA) method was applied to the same experimental results to describe linear elastic wave deformation processes based on experimental data containing known values of physical wave measurements for different types of liquid media, which was previously used to identify gases and predict the properties of various substances from the linear response of a normal acoustic-electronic wave. In this paper, a comparative analysis of the results obtained using polar histograms and the standard PCA classification method is performed. The advantages of the latter are demonstrated. The results of this study are useful both for the development of acoustic sensors without sensor layers and for the application of machine learning methods to data in other types of sensors.

Experiments and properties of low-energy nuclear reactions are presented.The existence of new ground states in the hydrogen atom, in the helium ion, and other hydrogen-like atoms located in a strong magnetic field at the appearance of third spatial oscillatory quantum number is shown. On the example of a transhelium atom, the possibility of pairing atomic electrons into an orthoboson is considered. The possibility of generating strong and ultra-strong magnetic fields in cosmic absolute plasma in the Photon era has been demonstrated, in which electrons recombine with protons and helium nuclei with the transition to transhydrogen and transhelium atoms. Transatoms combine into transmolecules and enter into multinuclear, radiation-free, low-energy reactions.The time of constant, natural nucleosynthesis has begun.The nucleosynthesis of carbon, nitrogen and oxygen atoms, when they were overwhelmingly surrounded by hydrogen atoms, led after the era of Recombination to intensive organic and bioorganic synthesis, which resulted in the origin of life and filling the entire Universe with that life. Low-energy nuclear reactions that occur in stars have been demonstrated.The possibility of natural nucleosynthesis occurring on Earth is shown.

В работе измерены суммарные потери акустических волн в пластинах 128°Y-LiNbO3 при нанесении жидкости, обусловленные радиационным излучением волн в жидкую среду, а также ее вязкостью, электропроводностью, плотностью и диэлектрической проницаемостью жидкостного аналита. В качестве тестируемых выбраны растворы с 5-ю базовыми вкусами, широко применяемые для калибровки и создания эталонов при тестировании жидких сред. Измерения проведены в диапазоне 30…60 МГц. Экспериментальные данные были представлены в виде полярных гистограмм, из сравнения площадей и формы которых определялся вкус того или иного раствора. К тем же экспериментальным результатам был применен метод анализа большого массива данных (РСА) для описания линейных процессов деформации упругих волн на основе экспериментальных данных, содержащих известные значения измерений физических показателей волны для различных типов жидкостных сред, который ранее использовался для идентификации газов и предсказания свойств различных веществ по линейному отклику нормальной акустоэлектронной волны. Выполнен сравнительный анализ результатов, полученных с помощью полярных гистограмм и стандартного метода классификации РСА. Продемонстрированы преимущества последнего. Результаты данного исследования полезны как при разработке акустических датчиков без сенсорных слоев, так и для применения методов машинного обучения к данным в других типах датчиков.

Esta proposición tiene sus raíces en diversas experiencias prácticas y en numerosos trabajos teóricos de lo que se denomina salud colectiva, en particular de la medicina social, que ayudan a enriquecer y justificar sus objetivos. El primer aspecto a destacar es la afinidad de esta investigación con la importante tradición crítica que, con diversos matices, ha caracterizado al campo de la salud colectiva en Brasil y, en un modo general, en América Latina. ¿Qué relación tiene la conformación y formalización de la epidemiología en la dirección del concepto de riesgo con el contradictorio movimiento de aprehender y simultáneamente negar la particularidad del espacio público de salud? ¿Cuál es la relación epistemológica entre el concepto fundador de una objetividad epidemiológica del concepto de medio externo, con el concepto actual de riesgo? ¿Cuál es el significado de la epidemiología del riesgo en el movimiento de progresiva “reducción instrumental” que marca la constitución de los axiomas de la epidemiología, al punto que algunos epidemiólogos contemporáneos [...] llegan a considerar que no se trata de una ciencia, sino solo de una metodología de investigación? A partir de estas investigaciones, la crítica histórico-epistemológica de la epidemiología intenta estructurarse como interrogante sobre cuánto y de qué modo el reciente paradigma del riesgo, en la intimidad de su tesitura científica, está en sintonía y/o tensión con el sentido instrumental asumido por la formalización del saber epidemiológico.

Published: May 2024

Sarcopenia is the loss of muscle mass and strength, or both, and physiological functions through aging. Early detection of muscle weakness results in better care and interventions regarding dietary habits and protein intake in older adults. The objective of this study was to investigate the prevalence of sarcopenia in a Pakistani population and to correlate dietary habits and lifestyle with the prevalence of sarcopenia. A sample size of 150 individuals, both male and female, of age sixty and above was used. Cardiovascular disease and renal failure patients were excluded. The research field was the community of Lahore. Muscle power was calculated using a handgrip strength dynamometer, and gait speed was calculated using a pedometer. After screening, muscle mass was calculated using bioelectrical impedance analysis, from which sarcopenia was diagnosed. In the age group of 60–65 years, 123 individuals (82%) had low muscle strength and 93 (83%) had low muscle mass. In the age group of 66–70 years, 15 individuals (83.3%) had low muscle strength. In the age group of 71–75 years, 9 individuals (90%) had low muscle strength. The percentage of low muscle strength in the age group of 76+ years was 100%. The percentage of severe sarcopenia was 6%, and moderate sarcopenia was approximately 10% for individuals 60 years of age and older. The prevalence rates of sarcopenia were 21.53% in males and 11.76% in females. Sarcopenia is an emerging health issue in older adults, and early detection and lifestyle modification will lead to a better health outcome and correlate dietary habits and lifestyle with the prevalence of sarcopenia.
Psychosocial elements as correlates of academic disposition of adolescents living with grandparents
Authors: Okorite Kienka Rita , Yetunde Fashina Abiola
Published: May 2024

Academic excellence from students is desirable to parents, but recently the passion to strive for such success seems to be dwindling among female adolescent secondary school students hence the need for this study which examined psychosocial elements as correlates of the academic disposition of adolescents living with grandparents.  A correlational research method was applied. Three research questions were raised and three hypotheses were formulated. The population comprised 253 female students randomly selected from nine senior secondary schools from four Local Government Areas of Education District III. Instruments used for data collection were the Rosenberg self-esteem scale and a self-developed questionnaire by the researcher tagged Academic Disposition and Sexual Proneness Questionnaire (ADSPQ). Data obtained were analyzed using descriptive statistics, Pearson Product Moment Correlation Coefficient, and Multiple Regression. Findings revealed that adolescent students living with grandparents in Education District III do not necessarily get involved in sexual activities because of their living conditions. One recommendation made was grandparents should be encouraged to engage in sexuality and sex-related conversations with their children as early as possible.

Planning and control in agri-food supply chains
Authors:   Kühne Logistics University, Germany, Cramer Florian , Transchel Sandra ,   Kühne Logistics University, Germany
Published: May 2024

In contrast to durable good supply chains, planning and control of agri-food supply chains are more challenging, e.g. due to perishable nature of the sensitivity of agri-food products. To provide managers with adequate decision-making support, it is crucial to understand the underlying planning processes along the entire supply chain. Recent events have shown that supply chain managers face various problems, from facilitating a transition to more sustainable food systems to securing food security by strengthening resilience. At the same time, an ever-growing population further exacerbates existing problems. This chapter explores the importance and complexity of planning processes in agri-food supply chains by briefly highlighting relevant building blocks for designing planning tools and by providing a comprehensive review on key planning elements, e.g. forecasting, production, and inventory planning. The primary focus is on planning and control activities based on techniques from operations management and quantitative methods from operations research and management science.

Darowizna w dzielnicowym prawie polskim w II RP oraz w kodeksie zobowiązań z 1933 r.
Authors: Baszak Łukasz
Published: May 2024

Tematem monografii jest darowizna w dzielnicowym prawie polskim w II RP oraz w kodeksie zobowiązań z 1933 r. Praca dotyczy aspektów obligacyjnych, a więc poza zakresem rozważań w zasadzie pozostaje wpływ, jaki darowizna wywierała w obrębie stosunków familijnych, regulacji prawnospadkowych, a także podatkowych. Zakres czasowy monografii obejmuje okres od odzyskania przez Polskę niepodległości w 1918 r. do wejścia w życie Kodeksu cywilnego z 1964 r. Celem pracy jest kompleksowa analiza umowy darowizny pod rządami kodeksów pozaborowych oraz kodeksu zobowiązań. Oprócz tego analizie poddana została również doktryna prawa w zakresie darowizny oraz orzecznictwo dotyczące darowizny, zarówno według ustaw pozaborowych, jak i kodeksu zobowiązań. Jak zostało udowodnione, koncepcja i konstrukcja prawna umowy darowizny w kodyfikacjach pozaborowych różniły się między sobą, przez co skutki prawne umowy darowizny były odmienne w poszczególnych dzielnicach państwa. Utrudniało to obrót cywilnoprawny w odrodzonym państwie polskim. Kodeks zobowiązań przezwyciężył ten partykularyzm dzielnicowy nie tylko poprzez ujednolicenie przepisów związanych z darowizną, ale również dzięki wprowadzeniu do swoich postanowień niektórych zagadnień z zakresu części ogólnej prawa cywilnego, które były szczególnie istotne dla funkcjonowania prawa zobowiązań. Stanowiło to ogromny postęp w porównaniu z poszczególnymi kodeksami dzielnicowymi. W niniejszej pracy wykazano, że polska regulacja prawna darowizny oparta była głównie na rozwiązaniach przyjętych w przepisach kodeksu cywilnego niemieckiego oraz częściowo na przepisach szwajcarskiego prawa o zobowiązaniach z 1911 r. (ZGB OR). W mniejszym stopniu skorzystano z rozwiązań przyjętych w austriackim kodeksie cywilnym, w Kodeksie Napoleona oraz w Zwodzie Praw Imperium Rosyjskiego.
Pharmacognostic Studies on the Stem Bark of Psidium guajava Linn
Authors: Chaudhuri Rai H. N.
Published: May 2024

The macroscopic and microscopic characters of the stem bark of Psidium guajava Linn, are described. Due to earlier defoliation of the previous cork layers the whole bark seems to consist of secondary phloem topped by cork cells. Absence of cortical tissue isone of the chief diagnostic characters. The bark is characterised by the presence of prismatic crystals of calcium oxalate in smaller phloem parenchyma cells, fusiform medullary ray cells terminated by tapering apical cells and absence of cortical and phloem fibres.

Some Observations on the Nomenclature of Fossil Dicotyledonous Wqods
Authors: Lakhanpal R. N. , Dayal Ramesh
Published: May 2024

It is apparent from the existing literature that there are many irregularities and inconsistencies in the nomenclature of fossil dicot woods. These are caused by such factors as disregard for the International Code of Botanical Nomenclature, insufficient knowledge of wood anatomy, poorly preserved material difference in the individual judgement of workers. It is, therefore, suggested that in order to bring uniformity in nomenclatural practices a common code should be agreed upon by all those engaged in the study of fossil woods.
