Simultaneous control of crystallite size and interlayer spacing of MoS2 to achieve pseudocapacitive lithium intercalation
Authors: Choi Jaehoon , Moon Hyein , Fleischmann Simon
Published: November 2023

The functional properties of molybdenum disulfide (MoS2) are highly dependent on its structure. Here, we present a one-pot hydrothermal synthesis approach allowing to simultaneous control MoS2 structure over several length scales. Lowering the pH of the hydrothermal precursor solution leads to smaller crystallite sizes of the pristine MoS2 formed. Moreover, the addition of alkyldiamines to the same precursor solution leads to their physical confinement between the forming MoS2 layers without the formation of covalent bonds, yielding interlayer-expanded MoS2. Controlling alkyldiamine precursor concentration can vary the number of confined structural pillars in interlayer-expanded MoS2. Electrochemical lithium intercalation is tested as a function of MoS2 structural properties. It is revealed that both smaller crystallite sizes and expanded interlayer-spacing lead to an increasingly pseudocapacitive lithium intercalation signature. The number of lithium that is reversibly stored in interlayer-expanded MoS2 is increased to almost 1.5 per formula unit. The results provide a facile synthesis approach to simultaneously control MoS2 crystallite size and d-spacing, which may be of interest for applications beyond lithium intercalation, such as multivalent ion intercalation or electrocatalytic hydrogen evolution.

Authors:   University of Žilina, Kardoš Miroslav
Published: November 2023

The use of airborne laser scanning technology is nowadays on the rise in Slovakia. The application of this technology in forestry is not lagging behind, and therefore it is important to examine and analyse the process of improvement and application of methods and their use in practice. Airborne laser scanning technology can penetrate under dense tree canopies and vegetation. We can map the terrain and the surface at the same time with relatively high accuracy. The main objective of this work is to validate the methodology of forest dentification, comparison with the reference data of the Land Registry and identification of forests on non-forest land – so called white areas on the basis of freely available airborne laser scanning data. White areas are areas covered with forest trees that are registered in the land register for purposes other than forest functions. The survey plots were selected regarding parameters of structure of forest land, existence of white areas and non-forest land. The data were obtained from the Geodesy, Cartography and Cadastre Authority of the Slovak Republic. The forest classification method was evaluated using the criterion of minimum tree height of 5 m. By comparison with reference data, we identified 2.30 ha of white areas in the area of interest. In conclusion, we proposed solutions for their further management in Slovakia.

Authors: Znamenskaya I.A. , Doroshchenko I.A. , Sysoev N.N.
Published: November 2023

A quantitative study has been made of the flow with shock waves generated in air by a sliding surface discharge lasting less than one microsecond. The high-speed flow was visualized using the shadowgraph method, the process was recorded at a rate of 124 000 frames/s, the exposure time was 1 μs. The aim of this work is to study the dynamics of the two discontinuities: the cylindrical shock wave and the contact surface generated by the discharge. Each experiment allowed several hundred images to be taken of a short-lived gas-dynamic process lasting up to 1 ms. A YOLOv8 convolutional neural network was trained and used to determine the positions of the discontinuities. A data set of 984 markups was labeled. The model on the mAP50 metric achieved 0.887 and the mAP50-95 was 0.557. The model was used to automatically measure the vertical dimensions of the contact discontinuity. It expands at times up to 0.4 - 0.8 ms to a vertical size of 5 - 11 mm. The x-t plots and the velocities of the cylindrical shock waves were measured. It is shown that up to 1 ms after the discharge, the flow development is due to the blast wind motion behind the shock wave. It is shown that the use of computer vision can significantly speed up the analysis of high-speed flow visualizations and the extraction of quantitative information.

The work is devoted to the application of previously developed algorithms and methods of stereo animations construction in the field of biological research on the example of stereo images for functional tomogram of the brain. The construction of stereo images on the autostereoscopic monitor provides an opportunity to obtain an in-depth understanding of the studied object. The autostereoscopic monitor allows viewing stereo images without glasses, while providing a quality not inferior to that of a classical 3D projection stereo system. This work continues the cycle of research conducted at the Keldysh Institute of Applied Mathematics. The specificity of the displayed data allowed to improve authoring libraries for creating stereo images. The research is aimed at developing technologies for constructing stereo images and animations for presenting the results of scientific calculations on classical stereo devices and autostereoscopic monitors. Constructing a stereoscopic visual representation of the results of biological research will enable researchers in the field to gain a deeper understanding of the object under study and its properties.

Published: November 2023

The paper is devoted to the issue of visualization of the algorithm for scheduling parallel tasks. Task scheduling is a key part of the online visualization and parallel programming environment developed by the author. When programming a parallel version of one mathematical application, a suspicion arose that the scheduling algorithm does not optimally distribute the load between the workers. In this connection, it was decided to visualize its work in order to see the overall picture and possible problem areas of the algorithm. The constructed view successfully coped with the problem, and the scheduling algorithm was improved.
Visualization of Calculations of the Discontinuous Particle Method in Problems with Viscosity
Authors: Bogomolov S.V. , Kuvshinnikov A.E.
Published: November 2023

In previous studies, it was shown that the discontinuous particle method performs well in computational hydrodynamics problems with strong gradients, exemplified by the formation of an oblique stress jump. This article explores the application of the discontinuous particle method to problems involving viscosity. The investigation includes a one-dimensional Burgers' equation with an initial condition in the form of a smoothed wave and a two-dimensional Blasius problem. Numerical experiments showed agreement between the obtained solution and the analytical one. However, in the two-dimensional case, the algorithm's performance significantly decreases due to the need to determine particle neighbors. It is concluded that the discontinuous particle method can handle viscosity problems in one dimension, but modifications to the existing algorithm are required for higher-dimensional cases. The study of applying the discontinuous particle method to viscous problems was conducted as part of a comprehensive research effort comparing the relative accuracy of numerical methods on benchmark solutions.

Sejarah Lahirnya Negara Islam Sekuler Turki dan Ide Perbaharuan Mustafa Kemal
Authors: Samsuriadi Samsuriadi , Santalia Indo , Wahyuddin Wahyuddin
Published: November 2023

Turki Utsmani yang tidak lagi diragukan dengan kekuasaan kesultanannya dengan Syaikhul Islamnya dimana sebagia lembaga keagamaan, mengatakan bahwasannya Islam tidak cocok dengan sekularisme. Ideologi tersebut bertolak belakang dengan pendapat Sultan, dimana Ideolagi Politik serta negara tidak mungkin dapat di pisahkan dari konsep Islam yang tidak memisahkan urusan negara dari urusan Agama. Pandangan  ini berbeda dengan perkembangan sajarah masyarakat Turki yang bersampingan dengan masuknya imperialisme Barat ke Dunia Islam yang diketahui pada awalnya membawa pemikiran sekularismenya dimana urusan Politik negara dipisahkan dari urusan Agama dan Keyakinan. Hal tersebutlah yang mempengaruhi kelompok Modernis Turki di bawah pimpinan Kemal, menuju Turki Modern. Naman muncul pertanyaan, mengapa kemal melaksakan politik sekularisme, bagaimana Negara Turki dapat menerapkan politik Sekularisme,  yang pada dasarnya kita ketahui bahwa mayoritas masyarakat Turki adalah Masyarakat Islam, oleh karena itu seharusnya umat Muslim lebih terbuka dalam mencerminkan ajaran Islam berdasarkan Al-Qur'an dan Al-Hadist  sesuai dengan kontekstualnya. Sehingga dapat menghasilkan bahwa Islam dan sekularisme  dapat bersinergi. Sehingga hal tersebut perlu di kembalikan pada bagaimana pandangan masyarakat terhadap Agama dan Sekularisme yang dipahami masing-masing Individu, serta peluhnya materi sekularisme turki ini menjadi refesensi untuk pengembangan sejarah Islam dalam Konsep Pemerintahan
Amanah Orang Tua Terhadap Perkembangan dan Pendidikan Anak Prenatal Dalam Perspektif Islam
Authors: Adhy Agung Wahyu , Tamam Abas Mansur , Rahman Imas Kania
Published: November 2023

AbstrakPendidikan anak adalah amanah yang Allah bebankan kepada para orang tua. Mereka adalah madrasah ula bagi anak-anak sebelum mereka mengenal sekolah formal. Pendidikan orang tua terhadap anak adalah amanah surat al-Tahrim ayat 6. Islam sangat memperhatikan pendidikan anak karena mereka akan menjadi Sumber Daya Manusia yang akan mempengaruhi perkembangan peradaban. Perhatian Islam terhadap pendidikan anak yang menjadi amanah bagi orang tuanya, dimulai jauh sebelum anak tersebut lahir ke dunia, yang dikenal dengan istilah pendidikan prenatal atau pra lahir. Sebelum terjadinya pembuahan (prakonsepsi), anak harus sudah mendapatkan hak yang disebut fase persiapan mendidik, di antaranya haknya adalah dipilihkan untuknya calon ayah atau ibu yang baik. Pendidikan kemudian berlanjut pascakonsepsi sampai anak dilahirkan. Pada fase ini peran orang tua sangat besar sekali. Orang tua pada masa pendidikan preanatal bisa memulainya dengan memberikan stimulus-stimulus yang dapat merangsang otak dan perkembangan syaraf sebelum lahir. Sayangnya pendidikan prenatal yang merupakan masa kritis bagi perkembangan fisik, emosi dan mental bayi masih jarang dilakukan oleh orang tua, padahal ini adalah bagian dari amanah orang tua terhadap anak-anaknya. Penyebabnya bisa karena kurangnya pengetahuan dan pengalaman, serta adanya anggapan keliru bahwa pendidikan anak baru dimulai ketika anak telah lahir yaitu pada masa preschool. Kata kunci: Amanah, Pendidikan, Prenatal AbstractChildren's education is a mandate that Allah burdens parents with. They are ula madrasas for children before they know formal schooling. Parental education for children is the mandate of Surat al-Tahrim verse 6. Islam pays great attention to children's education because they will become human resources who will influence the development of civilization. Islam's concern for children's education, which is a mandate for their parents, begins long before the child is born into the world, which is known as prenatal or prenatal education. Prior to conception (preconception), the child must have obtained the right which is called the educational preparation phase, one of which is the right to choose a good father or mother for him. Education then continues postconception until the child is born. In this phase the role of parents is very big. Parents during the prenatal education period can start by providing stimuli that can stimulate the brain and nerve development before birth. Unfortunately prenatal education which is a critical period for the physical, emotional and mental development of babies is still rarely carried out by parents, even though this is part of the mandate of parents towards their children. The reason could be due to a lack of knowledge and experience, as well as the mistaken assumption that a child's education begins only when the child is born, namely during the preschool period.Keywords: Mandate, Education, Prenatal

Published: November 2023

No período de dezembro de 2021 a março de 2022, o sudeste do Brasil foi afetado por eventos extremos de precipitação que culminaram em episódios de calamidade pública e óbitos. Os quatro casos de maior repercussão midiática foram os registrados em Brumadinho - MG (08 de janeiro), Petrópolis - RJ (15 de fevereiro e 20 de março) e Muriaé - MG (09 de fevereiro). Diante desse contexto, o objetivo do estudo é descrever o ambiente em escala sinótica que propiciou a ocorrência de cada um dos eventos extremos de precipitação mencionados. Para tanto, a principal base de dados utilizada é a reanálise ERA5. Já a metodologia baseia-se na análise sinótica dos campos atmosféricos. Entre os resultados têm-se que a característica comum nos quatro eventos extremos é a passagem de uma frente fria próximo à costa sudeste do Brasil que contribui para a canalização da umidade em tal região e que associada ao aquecimento local levam à ocorrência das tempestades.

A segurança hídrica é um dos temas centrais quando globalmente o assunto é Recursos Hídricos. A busca por novas fontes de captação de água bruta é uma realidade em muitos municípios do Brasil e em Viçosa, Minas Gerais não é diferente. Visando dispor de uma fonte alternativa para abastecimento público, que não seja um manancial superficial distante do centro urbano, este estudo tem por objetivo a pesquisa da água subterrânea como fonte de abastecimento urbano no município de Viçosa, para expansão do sistema existente a partir da análise integrada das características do relevo, da hidrografia, da geologia e dos lineamentos estruturais (fraturas/falhas) e comparar com vazões dos poços existentes na área de estudo. Para tal, foram realizados estudos e coleta de dados in loco, elaboração de planilha e mapas com informações dos poços tubulares existentes e análises da viabilidade executiva do sistema proposto. O estudo revelou tendências de locais e regiões propícias para a perfuração de poços, indicando um potencial para aproveitamento da água subterrânea. A pesquisa mostrou que os controles geológicos favoráveis a poços de boa vazão seriam restritos e específicos ao local estudado sendo uma característica intrínseca do sistema; que podem existir controles geológicos idênticos em diversos locais, ou seja, o sistema é aleatório, entretanto, nos mostraria a possibilidade de melhorar as locações de poços. Foram identificados na área estudada os aquíferos porosos, representados pelos aluviões e coberturas detríticas e manto de alteração e os aquíferos do meio fissural, representados pelas rochas da associação xistos-gnaisses-migmatitos.

A Note on a Synthetic Tetraploid in Asiatic Cotton
Authors:   Cotton Breeding Station Coimbatore, N KESAVA IYENGAR
Published: November 2023

It is frequently observed that when a wild species of cotton is crossed with the cultivated species, there is either very little setting or the hybrid is sterile. A number of workers like Mendes (1939), Beasley (1940), Harland (1940), Amin (1940, 1941), Stephens (1940), Zhebrak and Ozaev (1940) and Kasparyan (1940), have shown that it is possible to induce chromosome doubling in cotton and also to make sterile hybrids fertile when the sterility is due to failure of chromosome pairing as a result of the absence of homologous partner chromosomes. Attempts to induce chromo- some doubling in the sterile hybrids of cotton were made for two seasons, at the Cotton Breeding Station, Coimbatore. This note records the details of the trials made to transform a partially fertile hybrid between G. anomalum Wawra-et-peyr, (an African wild cotton with 26 somatic chromosomes) and G. arboreum, L (strain K. 1. with 26 somatic chromosomes)
The Cultivation of Dry Paddy in the Salur Taluk, Vizagapatam District.
Authors:   Agricultural Demonstrator Salur, P SOMAYAJULU
Published: November 2023

The hilly tracts and the plains of the Salur Taluk in the Vizagapatam District abound in good dry paddy varieties. Two of these viz., Veduru- sannam and Mettu dhanyarasulu are cultivated on a large scale. There are other varieties, Mettu prayaga and Mettu budagalu, which are also popular. During recent years Kasipichodi and Seethamma savaralu (prob- ably Seethasalo of Orissa) are found among the dry paddy. There is an area of about 1,000 acres under dry paddy during the current year in the taluk including the hilly area for which no statistics are maintained. Owing to the fall in the price of groundnut, and on account of propaganda for growing more food crops, the area under food crops has increased, partly replacing groundnut. In the following note the important practices in the cultivation of dry paddy are given together with a compara- tive statement of the cost of cultivation and yield of groundnut and dry paddy to show the advantages of cultivating the latter in these days.
Perennial or Tree Castor

Published: November 2023

The familiar forms of castor, Ricinus communis L. are the cultivated varieties raised either dry or irrigated. Distinct from these there also exist certain perennial tree types of which little is known. Mention is made of the perennial variety in most of the literature on castor, but in no instance has an attempt been made to distinguish it from the other types or yet to describe it fully. Popova (3), the Russian worker, makes mention of a wild type of castor growing in India and elsewhere but does not say whether it is a perennial type. Hil'tebrandt (2) recognises the perennial form but does not describe it. Bahl (1) has it that in tropical countries the castor plant reaches the dimensions of a small tree and may attain a height of 20' to 30 or more, with a stout trunk and branches. In cooler countries, he adds, it becomes a shrub or bush 8' to 12' high and in localities where frosts occur it is a herbaceous perennial. There are numerous other refer- ences also which go to show, that, though the existence of a distinct variety perennial in habit and growing into a tree has been known, no detailed study has so far been made of this variety. In this paper an attempt has been made to describe in detail the pere- nnial types collected from various parts of the Madras Presidency and indi- cate the similarities and differences between the cultivated and perennial varieties of castor. The agricultural utility of the tree form has also been discussed as it is felt that some of the economic forms may with advantage be brought under cultivation.
Cultivation and Marketing of Lanka Tobacco (Godavari Dt.)
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003, A SANKARAM
Published: November 2023

Among the provinces of India, Madras tokes the first place, with regard to consumption of tobacco in the form of cigars and cheroots. The annual per capita consumption is 372, and in the districts of Godavary and Vizaga- patam the use of cheroot is almost universal. Tobacco cultivated in the Lankas (islands) of Godavary otherwise known as Lanka tobacco is famous and popular throughout the Northern Circars as the best among the varie- ties grown for cheroots. This is chiefly due to the mild agreeable flavour, even burning and white ash qualities of the variety. Lankas are islands formed in the river beds of the Godavary. Depend- ing upon the nature of permanency, fertility value estimated on the amount of the silt deposited and cultivable nature of the soil, the lankas are classified into three main classes. A. Class: These are high level lankas and are free from easy submersion by floods. The chief crops raised in these are paddy, sorghum and tobacco. Major portions are set apart for grazing so as to give a chance of fallowing. These lankas are given on lease to the ryots for fixed terms of 10 to 20 years in public auction. The auction value generally ranges from Rs. 15 to 20 per acre per year.
The Search for Economic Plants
Authors:   Director, Royal Botanic Garden, Kew, W SIR ARTHUR HILL
Published: November 2023

The search for plants yielding spices and the history of their cultivation and use, as well as the story of the transport of the spices, is a romance which includes accounts of geographical discovery, monopolies, economic warfare, annexations of territories, and all the vices of theft, envy, hatred and malice, and all uncharitableness enumerated by the Apostle St. Paul. Perhaps the spice which should be put in the forefront is pepper (Piper nigrum), native of Malabar and of the forests of Travancore, a spice now too seldom seen or appreciated in its natural conditions as black pepper corns, which was the staple article of trade between Europe and India for many ages. Most people to-day use white pepper, which is the small berry-like fruit or peppercorn, ground after its pericarp has been removed, thus depriving it of some of its pungency and best seasoning qualities.

On the Agricultural Research Station, Aduturai, there was a large quantity of molasses available as a bye-product, in connection with the trials for manufacturing white sugar by the open pan system with centrifugal machine. The trials were conducted during the years 1933-37. Part of it was fed to cattle, but the surplus let over could not be easily disposed of by sale in the locality. So, it was decided to try molasses as a manure on the swamp paddy on the station.

The pickles form an indispensable side-dish in our diet. They are considered to be appetisers and to help in digestion. Of the several kinds of pickles in common use, Mango ginger is a special favourite with the Andhras in the Northern Circars. In the preparation of this pickle the addition of an adequate amount of lime juice, besides the required quantities of chillies and salt, is essential to give a pleasing taste. Mango ginger (Curcuma Amada Roxb.) belongs to the family Zingiber- aceae. Like the other members of the family, the plant is a perennial herb with an underground rhizome and large erect leafy aerial branches. plant grows wild in Bengal and on the hills. The The cultivation of the crop is mainly concentrated in and around Anakapalli, though recently it is known to have been taken up by a few ryots in the villages round about Rajahmundry of the East Godavari District. The details of the cultivation of this crop as practised in the neighbourhood of Anakapalli are presented in this short note.

Agricultural Engineering in India.

Who is an agricultur+1 engineer? By American practice the term is applied only to those who have pursued a definite course of training in engineering and its application to agriculture. In England, apparently so far as I can judge by literature coming to me, an agricultural engineer is one who is engaged in the marketing of agricultural implements or in their manufacture and the term does not depend on what training the individual muy have bad, if any at all, other than experience. So far as I can determine, in Indin the term is applied to any engineer without regard to the branch of engineering in which he may have been trained who is assigned to a post carrying the title of Agricultural Engi- neer' usually in Government service.
Bananas of the Travancore State

The terms banana and plantain are synonymous. Banana is the name used in foreign countries for what is called plantain in India. Nendran (Eththan) which is generally known as banana in Travan- core is called plantain by English speaking people elsewhere. The term banana may, therefore, better be used for all varieties of plantains including Nendran.
Agricultural Progress in India During the Decade 1929-1939

Published: November 2023

Ever since I undertook to deliver this lecture I have marvelled at my temerity and, indeed, it is impossible to do justice to my subject. Not only is one dealing with the varied agriculture of a sub-continent peopled by 400 million people of several races, but also with several distinct systems of agriculture based on widely differing soil and climatic conditions. Progress has been marked and general, but it has taken many forms. My choice of this period fo review was largely governed by the fact that, speaking broadly, it coincides with the decade following the report of the Linlithgow Commission. The decade under review was a notable one for other reasons, for Indiar agriculture, like that of many other countries, had to adapt itself to the condi- tions arising from the world economic depression. Equally important was the effect on agriculture of industrial progress within India, leading to a demand for increased quantities and better qualities of the natural products which form the raw materials of industry. Above all, the increase in population afforded larger outlets for agricultural products, the demand being intensified by a distinct increase in the general standard of living. Indeed, India almost ceased to be an exporter of wheat and other cereals, despite a considerable expansion of pro- duction. To-day, however, I propose to confine myself in the main to a brief account of the steps which were taken to implement the recommendations of the Royal Commission and the results which have been schieved. My task has been lightened by the reports made to the Government of India in 1937 by Sir John Russell, und by Dr. Norman Wright.

That the production of profitable crops of marketable size and quality is the end-result of a long series of factors is a well established fact. Broad- ly, these factors can be classified under iwo groups-one, which is partially or completely under the control of the grower and another, which is not. The latter group comprises of mainly a complex series, which can be con- veniently summarised under the heading of climate or season, and which may directly or indirectly exert a determining influence upon crop size. Even though this group of factors is beyond the control of man, it is possi- ble to establish significant correlation between each of the factors consti- tuting this group and the tree-performance, and thus obtain a precise know- ledge of the optimum cultural practices in relation to the various types of tree-requirements as modified by this group of factors. In the chain constituting the other group of factors, there are undoubt edly numerous links to be considered. This group of factors demands special care of the grower, as by a proper understanding of the influence of some or all of these factors it is not only possible to ensure better crops in normal years, but it may also enable the grower to reduce or minimise the losses resulting from unfavourable conditions not directly or easily con- trollable.
Groundnut as Human Food.
Authors:   Oilseed Specialist, Agricultural Reserch Institute, Coimbatore, C.M JOHN
Published: November 2023

The food-stuffs that we consume should contain the right amount and kind of proteins, fats, carbohydrates, vitamins and mineral salts, if we are to live in normal health and our body is to function properly. Each of these ingredients supplies some requirement or other of the body complex. Proteins are necessary for building the muscles; carbo- hydrates are the body's chief source of energy; fat is the heat producer while mineral salts and vitamins play an important part in the physiological functions. Any one food-stuff that is available to man may not contain all the above ingredients, so that by consuming one particular product we can- not supply the full requirements of the body. Therefore, we must combine them judiciously so that our daily diet contains all these essential ingredi- ents in the right proportions.
Maintenance of Purity of Cumbu Strains under Large Scale Seed Multiplications.
Authors:   District Agricultural Officer , Tirunallvely, M.A BALAKRISHNA IYER
Published: November 2023

In no phase of agriculture there is greater need for careful planning than in the maintenance of the purity of the improved strains of crops dur- ing the course of their multiplication and distribution. It is more so in the case of crops which are mainly cross-fertilized. The criterion of the methods adopted should be such as to combine minimum cost with efficiency in ensuring against cross-fertilization with other varieties. Otherwise, costly methods of selfing followed in the seed nucleus plots would soar to a staggering amount when adopted for large scale seed farms. Lack of cheap and suitable methods for protecting the purity of the crop have all along proved a sericus handicap for the rapid spread of high yielding cumbu strains in the black soils of the Tinnevelly District.
Some Factors Governing Fruit-bud Formation in Mangoes (Mangifera indica Linn.) II Relation Between Growth and Flowering.

Published: November 2023

A correct understanding of the relationship between various growth features and productivity was shown in the previous paper as essential in successful mango production. Productivity is the ultimate manifestation of the tree performance, from the grower's point of view. But a comparison of this ultimate phase with the growth features does not appear to be valid for the purpose of determining the most useful features of growth for ensuring high production and regular bearing in mangces. The correct basis of study in a problem of this nature would be flowers and not fruits. Flower is undoubtedly a preliminary to fruit, but it does not follow from this that a heavy crop of flowers is always followed by a heavy crop of fruits. It is the universal experience of mango growers that, in several years flowers shed either due to environmental influences or, as is very often the case, due to a heavy attack of hoppers. A bumper crop of blossoms may be entirely lost, turning a prospective good year into one of extreme scarcity. To study the problem of the so-called periodicity or biennial bearing solely on the basis of fruit crop records in the face of these well-known disturbing factors, a good part of which is beyond human control, is naturally not the proper course. The work reported in this paper has therefore been carried out on the above-mentioned basis, viz., that of blossom.
