Here we report the case of a 34-year-old man who underwent endoscopic removal of a tablespoon from the stomach that was lodged within the duodenum.Removal required the use of a two-channel upper endoscope and polypectomy snares.Using the doublesnare technique, the spoon was grasped at the proximal and distal parts of the handle.The doublesnare was first pulled unsuccessfully and then pulled with simultaneous manual abdominal compression of the bulbus from the body surface.Compression was gently applied towards the stomach.As a result, the head of the spoon prolapsed from the bulbus, and was easily retracted from the stomach without any complications.In cases of foreign body lodging within the duodenum, the manual abdominal compression technique may help clinicians pull out the object and avoid surgery.The usefulness of manual compression is dependent on the foreign body's sharpness and the location. 展开更多

The contemporary English novelist and literary critic David Lodge has published sixteen works of fiction,including the latest published short story collections The Man Who Wouldn't Get Up and Other Stories(2016).In this work,the first story The Man Who Wouldn't Get Up is the earliest one which was written in the winter of 1965-1966 and mainly tells about a professional man who refuses to get up in order to escape the harsh world and I chiefly discuss the paratexts of it.Gerard Genette defines paratexts as"are those liminal devices and conventions,both within and outside the book,that form part of the complex mediation between book, author, publisher, and reader:titles,forewords,epigraphs,and publishers'jacket copy are part of a book's private and public history."In this paper,I adopt Genette's theory of paratexts which provides a unique theoretical approach for fiction study and apply it to the analysis of Lodge's The Man Who Wouldn't Get Up and Other Stories.The work is rich in miscellaneous paratexts which are one of the characteristics of this work and aid comprehension while shortening the distance between author and reader.The paper mainly examines the peritext:the elements inserted into the interstices,such as,the cover,title,epigraph,biography of the author,reviews of the book,foreword,jacket copy,illustration,dedication,afterword and acknowledgements.Investigating the peritexts of the work indicates the unique function and the significance of the thresholds of interpretation to the fictional text.Ultimately,they become the medium of communication between the author,the text and the reader,and are exemplary of Lodge's creativity and hybrid narrative style. 展开更多

It is a slow growing lesion and may become voluminous causing the patient an aesthetic disfigure. The diagnosis is made by the histological examination combined with immunohistochemical analysis. Radiological features present a variety of description because of the proportions difference of spindle cell lipoma components, but imaging is useful to determine the mass extents. The treatment of this kind of benign tumors is surgery which must be completed without need for other therapy. <strong>Aim:</strong> This case report highlights the exceptional location of spindle cell lipoma in the soft tissues of the parotid-masseter lodge, which may raise differential diagnosis problems with a primary parotid gland tumor. <strong>Case Presentation:</strong> A 58-year-old man, with no medical history, was presenting a swelling of the parotid region, growing progressively for 6 years, without other associated sign. The patient benefited from a careful physical examination. A computed tomography and magnetic resonance imaging were carried out. Clinical and radiological findings were suggesting a benign tumor occupying the left parotid-masseter lodge. The patient went through a surgical excision of the tumor. Histological and immunohistochemical features revealed a classic shape of spindle cell lipoma. After one year of follow-up, we notice a good recovery without local recurrence. <strong>Conclusion:</strong> Surgeons and pathologists have to keep in mind the possible development of spindle cell lipoma in any subcutaneous site even if unusual one. 展开更多

The harvesting difficulty caused by corn lodging aggravated the loss of grain,especially in the regions where small harvesters were used as the main force for corn harvesting.An experimental study and analysis of harvest loss of small harvesters on the root lodged corn were made to get the laws of lodged corn harvest loss.The experiment was conducted in different harvesting directions and at a range of harvesting speeds.A 4-row self-propelled corn harvester(JM-4Y),a 2-row crawler type self-propelled corn harvester(JM-2C),and a 2-row crawler-type corn harvester equipped with a spiral auxiliary feeding device for lodged stalks(JM-2CAF)were taken as the research objects and the grain loss per square meter and the ear loss quantity per 30 square meters were taken as the experiment indices.The results showed that the average grain loss masses of the JM-4Y harvester,the JM-2C harvester and the JM-2CAF harvester in different harvesting directions were 101.88g,285.72 g and 110.20 g,while the average corn ear losses were 10.08,33.54 and 9.28 pieces.The lowest harvest loss of the JM-4Y harvester appeared when the harvesting was the same as the lodging direction,while the JM-2CAF harvester caused the lowest harvest loss when the harvesting direction was opposite to the lodging direction.The different feeding demands of the ordinary harvester head and the auxiliary feeding devices made the harvesters have different feeding conditions.At different harvesting speeds,the average grain loss mass of the JM-4Y harvester,the JM-2C harvester and the JM-2CAF harvester were 139.06 g,453.42 g and 236.64 g while the average corn ear loss quantities were 15.12,52.52 and 34.80 pieces.The JM-4Y harvester had the lowest harvest loss at almost every harvesting speed,and the JM-2CAF harvester only had lower harvest loss when the harvesting speed was lower than 0.8 m/s.The insufficient time to lift and deliver the lodged stalk and the impact between the spiral blades and the stalks were the causes of harvest loss when harvesting speed got higher.This study provides practical and theoretical references for the loss reduction of lodged corn harvesting. 展开更多

Direct-seeding rapeseed production at high plant density raises the risk of lodging.We investigated the use of dwarf genes to improve rapeseed plant architecture to balance yield and lodging.Three genotypes with different plant architectures(dwarf sca^(HS5),semi-dwarf+/sca^(HS5),and tall ^(HS5))were evaluated under varying nitrogen rates(N1,N2,and N3:120,240,and 360 kg N ha^(-1))and plant densities(D1,D2,and D3:15,45,and 75 plants m^(-2))from 2019 to 2022.The results showed that increasing N rate positively influenced yield while decreasing lodging resistance in all genotypes.Increasing plant density(D2-D3)enhanced lodging resistance and yield in sca^(HS5) and+/sca^(HS5),but reduced yield in ^(HS5).Compared to the two parents,+/sca^(HS5) exhibited moderate expressions of IAA3,GH3.15,and SAUR30 in stems under N2D3,resulting in reduced plant height and increased compactness.Additionally,+/sca^(HS5) had a thicker silique layer than ^(HS5) by 14.7%,and it had a significant correlation between branch height/angle and yield.Increasing N rate led to increased lignin and pectin contents,while cellulose content decreased.Increasing plant density resulted in greater stem cellulose content and CSLA3/7 expression in sca^(HS5) and+/sca^(HS5),but decreased in ^(HS5).Compared to ^(HS5),+/sca^(HS5) exhibited higher expressions of ARAD1 and GAUT4,along with a 51.1%increase in pectin content,leading to improved lodging resistance under N2D3.Consequently,+/sca^(HS5) showed a 46.4%higher yield and 38.9%lodging resistance than ^(HS5) under N2D3,while sca^(HS5) demonstrated strong lodging resistance but lower yield potential.Overall,this study underscores the potential of utilizing auxin dwarf genes to optimize the trade-off between yield and lodging resistance in rapeseed and the possibility of maximizing yield potential by optimizing the plant architecture of+/sca^(HS5) through nitrogen reduction and dense planting. 展开更多

Lodging is still the key factor that limits continuous increases in wheat yields today,because the mechanical strength of culms is reduced due to low-light stress in populations under high-yield cultivation.The mechanical properties of the culm are mainly determined by lignin,which is affected by the light environment.However,little is known about whether the light environment can be sufficiently improved by changing the population distribution to inhibit culm lodging.Therefore,in this study,we used the wheat cultivar“Xinong 979”to establish a low-density homogeneous distribution treatment(LD),high-density homogeneous distribution treatment(HD),and high-density heterogeneous distribution treatment(HD-h)to study the regulatory effects and mechanism responsible for differences in the lodging resistance of wheat culms under different population distributions.Compared with LD,HD significantly reduced the light transmittance in the middle and basal layers of the canopy,the net photosynthetic rate in the middle and lower leaves of plants,the accumulation of lignin in the culm,and the breaking resistance of the culm,and thus the lodging index values increased significantly,with lodging rates of 67.5%in 2020–2021 and 59.3%in 2021–2022.Under HD-h,the light transmittance and other indicators in the middle and basal canopy layers were significantly higher than those under HD,and the lodging index decreased to the point that no lodging occurred.Compared with LD,the activities of phenylalanine ammonia-Lyase(PAL),4-coumarate:coenzyme A ligase(4CL),catechol-O-methyltransferase(COMT),and cinnamyl-alcohol dehydrogenase(CAD)in the lignin synthesis pathway were significantly reduced in the culms under HD during the critical period for culm formation,and the relative expression levels of TaPAL,Ta4CL,TaCOMT,and TaCAD were significantly downregulated.However,the activities of lignin synthesis-related enzymes and their gene expression levels were significantly increased under HD-h compared with HD.A partial least squares path modeling analysis found significant positive effects between the canopy light environment,the photosynthetic capacity of the middle and lower leaves of plants,lignin synthesis and accumulation,and lodging resistance in the culms.Thus,under conventional high-density planting,the risk of wheat lodging was significantly higher.Accordingly,the canopy light environment can be optimized by changing the heterogeneity of the population distribution to improve the photosynthetic capacity of the middle and lower leaves of plants,promote lignin accumulation in the culm,and enhance lodging resistance in wheat.These findings provide a basis for understanding the mechanism responsible for the lower mechanical strength of the culm under high-yield wheat cultivation,and a theoretical basis and for developing technical measures to enhance lodging resistance. 展开更多

Nitrogen(N)significantly affects rice yield and lodging resistance.Previous studies have primarily investigated the impact of N management on rice lodging in conventional rice monoculture(RM);however,few studies have performed such investigations in rice-crayfish coculture(RC).We hypothesized that RC would increase rice lodging risk and that optimizing N application practices would improve rice lodging resistance without affecting food security.We conducted a two-factor(rice farming mode and N management practice)field experiment from2021 to 2022 to test our hypothesis.The rice farming modes included RM and RC,and the N management practices included no nitrogen fertilizer,conventional N application,and optimized N treatment.The rice yield and lodging resistance characteristics,such as morphology,mechanical and chemical characteristics,anatomic structure,and gene expression levels,were analyzed and compared among the treatments.Under the same N application practice,RC decreased the rice yield by 11.1-24.4% and increased the lodging index by 19.6-45.6% compared with the values yielded in RM.In RC,optimized N application decreased the plant height,panicle neck node height,center of gravity height,bending stress,and lodging index by 4.0-4.8%,5.2-7.8%,0.5-4.5%,5.5-10.5%,and 1.8-19.5%,respectively,compared with those in the conventional N application practice.Furthermore,it increased the culm diameter,culm wall thickness,breaking strength,and non-structural and structural carbohydrate content by 0.8-4.9%,2.2-53.1%,13.5-19.2%,2.2-24.7%,and 31.3-87.2%,respectively.Optimized N application increased sclerenchymal and parenchymal tissue areas of the vascular bundle at the culm wall of the base second internode.Furthermore,optimized N application upregulated genes involved in lignin and cellulose synthesis,thereby promoting lower internodes on the rice stem and enhancing lodging resistance.Optimized N application in RC significantly reduced the lodging index by 1.8-19.5%and stabilized the rice yield(>8,570 kg ha~(-1)on average).This study systematically analyzed and compared the differences in lodging characteristics between RM and RC.The findings will aid in the development of more efficient practices for RC that will reduce N fertilizer application. 展开更多

The Congolese population is organised into households, which are thus headed by a chief who ensures the social well-being, development and integration into working life of the individuals in his charge. This study examines the functional principles of new housing design as an instrument for transforming the (current) failing economy into a strong and resilient one. Accordingly, a literature review of the practice of designing and building housing in human settlements in the Congo revealed the state of the art on this subject. An analysis of the existing housing stock from a demographic, social and economic point of view made it possible to identify the most common household sizes and numbers, as well as the lifestyle processes that determine the need for developed space. To this end, the experimental method was used to propose configuration plans for various new types of dwelling. To this end, the study highlighted the link between people’s standard of living and the effectiveness of their involvement in the local economy. To achieve the aims of the National Development Plan (NDP), particular attention must be paid to solving the housing problem. The existing housing stock actively contributes to the problems associated with unemployment and insecurity. Functional principles for the design of new types of housing have been developed. Four model types are proposed in line with the demographic structure of the population, their socio-economic characteristics and their lifestyle. 展开更多

[Objective] To study the correlation between the biomechanical properties of rape stalks and rape stem lodging. [Method] Through axial compression tests to the stalks of 4 different rape varieties, the change rules of maximum stem bearing ca- pacity, maximum compressive strength, elastic modulus and moment of inertia along plant height were analyzed, as well as the effect of different varieties and water contents on the biomechanical property indices of rape stalks. [Result] The maximum loads of rape stalks presented liner decrease trend along with the increase of stem height, and all reached the maximums below the height of 50 cm. The maximum stem compressive strength and elastic modulus of the 4 varieties were increased with ascending height, but in a slow rate with small change, thus the modulus of e- lasticity could be considered as unchanged. The maximum bearing capacity, maxi- mum compressive strength and elastic modulus of dry rape stalks were higher than wet stalks, indicating that the water contents of rape stalks had significant effect on their mechanical properties. According to the actual lodging situations in filed, stalks of variety No. 1 owned the worst biomechanical properties and lodging degree, while the biomechanical properties of No. 6 and F5 were better than No. 1 and No. 9, and they also had stronger lodging-resistance. [Conclusion] The study provides parameters and bases for the design of mechanized production and mechanical deep processing of crops, and can better reveal the physical natures of organisms. The methods used in this study can also be used to screen excellent crop stalks. 展开更多

[Objective] The experiment was conducted to explore the suitable planting density and nitrogen amount for summer maize in Sichuan Basin with the objective to provide technical reservation and scientific basis for high-yielding cultivation technique.[Method] A widely planted maize cultivar 'Chengdan 30' was used as experimental material to study the effects of planting density and nitrogen amount on the stalk agronomic traits,stalk lodging-resistance mechanical characters,stalk breaking percentage and yield of maize.Experiment was arranged in a two-factor split plot design with three replicates.The planting density was the main factor with three density gradients(4.5×10^4,6.0×10^4 and 7.5×10^4 plants/hm^2) and the nitrogen amount was the second factor with two different levels of nitrogen content(300 and 375 kg/hm^2).[Result] The stalk lodging-resistance and yield were affected by planting density significantly.The increase of planting density would result in an increase of internode length and decrease of internode diameter,dry matter weight of per unit stalk length,rind penetration strength and breaking resistance of 3rd and 4th basal internodes.When planting density increased from 6.0×10^4 plants/hm2 to 7.5×10^4 plants/hm^2,the stalk breaking percentage in the whole growing season increased by 17.17%,and the yield reduced by 17.58%.The interaction between planting density and nitrogen amount affected the stalk breaking percentage in the whole growing season and yield significantly.The treatment with planting density of 6.0×104 plants/hm^2 and nitrogen amount of 375 kg/hm^2 of pure N was an optimal combination,which may not only control the stalk breaking percentage of whole growing stage effectively,but also could obtain an optimum grain yield.[Conclusion] In Sichuan Basin,the appropriate planting density and nitrogen amount for summer maize were 6.0×10^4 plants/hm^2 and 375 kg/hm^2. 展开更多

[Objective] This study is to map QTLs for lodging-related morphological traits of soybean, aiming at providing basis for breeding lodging-resistant varieties. [Method] To map the QTLs for lodging-related morphological traits, an F216-F218 RIL population containing 147 lines derived from a cross between Charleston as female and Dongnong 594 as male parent were used as experimental materials in this study. Totally 164 SSR primers screened out from amplification on two parents, were employed to amplify the F216-F218 RIL population for constructing a genetic linkage map. The QTLs for nodes on main stem, stem thickness and stem weight of the F216-F218 RIL soybean population were investigated in two eco-environments for three years. [Result] Sixteen QTLs for nodes on main stem were detected in A1, B1, C2, Dla, D2, F, G, H and N linkage groups, respectively; Ten QTLs for stem thickness in A1, B1, C2, Dla, E and G linkage groups, respectively; Fifteen QTLs for stem weight in A1, A2, C2, Dla, Dlb and G linkage groups, respectively. Of these QTLs, five for nodes on main stem, one for stem thickness and six for stem weight could be detected by both CIM and MIM, accounting for 8.6%-27.0%, 9.0%- 11.0%, and 6.0%-39.0% of the general phenotypic variation, respectively. From ex- perimental data of two years, Three QTLs for nodes on main stem and two for stem weight could be detected, accounting for 8.0%-60.2% and 10.0%-23.0% of the general phenotypic variation, respectively; while no QTL for stem thickness was re- peatedly detected during more than two years. [Conclusion] Comparison of the QTLs mapped for nodes on main stem, stem thickness and stem weight indicates that these three morphological traits are closely related with lodging-resistance of soybean. 展开更多

The stem morphology and anatomical structure of rice, as well as their relationship with lodging resistance, were studied with six super hybrid rice varieties as the tested materials. The results showed that the rice varieties with stronger lodging resistance were characterized by shorter basal elongated internodes and thicker stem base. The lodging index of hybrid rice was positively correlated with the lengths of the first, second and third basal elongated internodes (P〈0.01) and was negatively correlated with the thickness of basal stem wall and the number and area of small vascular bundles, the area of large vascular bundles and the total area of vascular bundles of the second basal elongated internode (P〈0.05). The correlations between lodging index and plant height, maximum culm diameter of stem base and minimum culm diameter of stem base were not significant. It indi- cates that the lodging resistance of super hybrid rice can be improved by shorten- ing the length of basal elongated internodes, thickening the wall of stem base and increasing the number and area of vascular bundles of basal elongated internodes. 展开更多

Objective] This study was conducted to investigate the main factors affect-ing the lodging resistance of plateau japonica rice. [Method] Twenty agronomic traits related to lodging resistance of plateau japonica rice were analyzed by principal component analysis and correlation analysis among 26 varieties/lines of plateau japonica rice. [Result] The lodging resistance of the 26 varieties/lines had great dif-ference among different agronomic traits. Plant height, and wal thickness of the 4th, 3rd and 2nd internodes under the panicle had the most important influence on lodging resistance, while the diameter of the 3rd, 2nd, 4th, 1st nodes under the panicle, length of the 4th and 3rd internodes under the panicle, wal thickness of the 1st internode under the panicle had less influence. The other nine agronomic traits of rice culm did not affect or indirectly affected lodging resistance through above-mentioned agro-nomic traits. Lodging resistance had significant correlations with plant height, length of the 4th and 3rd internodes under the panicle, wal thickness of the 1st, 2nd, 3rd and 4th internodes under the panicle and diameter of the 1st, 2nd, 3rd and 4th node sunder the panicle, had insignificant correlations with panicle length, panicle weight, length of the 1st and 2nd internodes under the panicle, diameter of the 1st, 2nd, 3rd and 4th internodes under the panicle, diameter of the 5th node under the panicle.

The research reviewed use effects of Yuhuangjin, Xishibao, Zhuangfengling and Jianzhuangsu on Jinhai No. 5. The results showed plant height and ear height declined in varying degrees, as well as empty-stalk rate and lodging rate, with the plant growth regulators applied. Economic characters all improved, including ear length and diameter, barren-tip length and hundred-seed weight, and corn yield went up significantly on average. For example, the increased yield can be as high as 17.43% when Yuhuangjin was applied at 30 ml/hm^2. 展开更多

[Objective] This study aimed to investigate the effects of different fertilizer levels on lodging and yield of rice. [Method] A total of four treatments were designed and applied with 6, 9, 12 and 15 kg of nitrogen fertilizer, respectively. After seedling transplanting, the biological characteristics of rice at different growth stages in each treatment and the biological and economic characteristics of rice after lodging were determined for statistical analysis. [Result] Application with 15 kg of nitrogen fertilizer had significant promotion effect on the increase of rice yield; compared with the control (6 kg of nitrogen fertilizer), rice yield in three experimental treatments (9, 12 and 15 kg of nitrogen fertilizer, respectively) increased by 50.74%, 89.11% and 94.48%, respectively; lodging-resistance mechanical strengths of the three experimental treatments were 103.97%, 132.01% and 89.83% of the control, respectively; rice lodging resistance of treatment C (12 kg of nitrogen fertilizer) was the strongest, with the highest yield. [Conclusion] This study provides reference data and technical support for the rational fertilization of rice production. 展开更多
