Investigation of the effects of bimaxillary surgery on the pharyngeal airway space
Authors: Koç Ezgi , Akkurt Atılım
Published: March 2023

Aim: To examine the pharyngeal airway space (PAS) changes in patients with skeletal Class III anomalies treated with two different bimaxillary surgery (BMS) techniques.
Methodology: A total of 27 patients (15 females, 12 males) treated with BMS were divided into two groups: Group 1 (n=16, mean age: 20.67±2.82 years) consisted of patients who underwent maxillary-mandibular advancement (MMA), and Group 2 (n=11, mean age: 23.87±7.72 years) consisted of patients who underwent maxillary advancement and mandibular setback (MAMS). Cone-beam computed tomography (CBCT) records were taken immediately before (T1) and at least 5 months after (T2) BMS. To evaluate the postoperative PAS changes, the parameters of total volume (TV), upper volume (UV), lower volume (LV), and minimal axial area (Min-Ax) were evaluated using NemoCeph 10.4.2 software.
Results: In Group 1, postoperative increases in the TV, NV, OV, and Min-Ax were determined as 4.5%, 6.6%, 3.07%, and 5.1%, respectively, but these increases were not statistically significant (p > 0.05). In Group 2, the following increases were determined: 10.4% in TV, 18.4% in NV, and 5.5% in OV. A postoperative decrease of 6.2% was determined for Min-Ax. These increases and decreases were not statistically significant (p > 0.05). There was no statistically significant difference between groups 1 and 2 in any pre- and postoperative parameters (p > 0.05).
Conclusion: Neither of the BMS techniques caused any significant change in the PAS parameters.

Authors: Altaş Nurcan , Aydınoğlu Aysu , Gözetici Çil Burcu , Keleşoğu Ergün , Sağır Kadir , Hazar Yoruç Afife Binnaz
Published: March 2023

Aim: Air powder polishing (APP) can cause roughness on composite surfaces, and consequently the color change that occurs over time affects the aesthetic negatively. Here, we aim to investigate the effect of repolishing on the roughness and discoloration of resin composites after APP to avoid its negative effects for the first time.
Methodology: A total of 39 composite discs were randomly allocated into three groups: Group I: Control (n = 13), Group II: Air Powder Polished (n = 13), and Group III: Air Powder Polished + Re-polished (n = 13). Color and surface roughness of the discs were measured before and after immersion in coffee for 1 week. Color was measured using a colorimeter (CR-400, Konica Minolta), and roughness was measured using a surface roughness analyzer (SJ-400, Mitutoyo, Japan).
Results: All specimens in the groups, except those in Group III, showed significant changes in roughness, and all materials showed significant color changes after immersion in the coffee relative to the baseline. There was no statistically significant difference between the groups in terms of roughness and color.
Conclusion: In this study, we showed that repolishing after APP does not significantly improve the color stability and roughness of the composite restorations.

Surface roughness evaluation of composite materials polished with one- or multi-step systems
Authors: Ozan Günçe , Berkman Meriç
Published: March 2023

Aim: As the spectrum of composite materials expands in the dental market, it's becoming more challenging to differentiate the structural properties and to find suitable finishing-polishing (f-p) materials. The main goal is to evaluate the impact of one and multi-step f-p systems on the surface roughness (SR) of current composite materials.
Methodology: In this study, nanohybrid bulk-fill (Filtek BulkFill Posterior [FBFP]), nanohybrid (Ceram.x One [CXO]), microhybrid (Filtek Z250 [FZ250]), and giomer bulk-fill (Beautifil Bulk Restorative [BBR]) composites were tested. After sample preparation and 24-h storage in 37 °C distilled water, each main group was assigned to one of two groups (n = 10): a one-step (One Gloss-PS) or a multi-step (Sof-Lex) f–p system. SR values (Ra, µm) were measured using a profilometer. Statistical analysis was done using Tukey HSD and ANOVA tests (p < 0.05).
Results: FZ250 showed the highest Ra values, regardless of the f–p system used. CXO showed statistically significantly lower SR scores than FZ250 (p < 0.05). There were no significant differences among the Ra values of the one- or multi-step f–p systems for FBFP and FZ250. Both the material and f–p systems had a significant effect on the Ra values separately.
Conclusion: FZ250 showed the highest Ra values, and composites polished with the multi-step f–p system exhibited slightly smoother surfaces than those polished with the one-step system.

Lack of high-yielding climate-resilient varieties and, frequent pest and disease incidences are the major issues in tomato production in Bhutan. The National Centre of Organic Agriculture, Yusipang, introduced 40 open-pollinated entries between 2020 and 2021. With an objective to evaluate and select the most desired tomato varieties for commercial cultivation in Bhutan, seven tomato entries were prescreened and selected using combined scoring of the total votes from the Participatory Varietal Selection and yield of entries in 2021. The Randomized Block Design with eight entry treatments and three replications with Ratan as standard check was employed to evaluate their yield and yield parameters; fruit quality; and tolerance to pests and diseases in 2022. ANOVA followed by Tukey HSD test for mean separation was employed at p-value at P<0.05. The result showed that AVTO1954 produced a significantly higher yield (29.8 tons/acre) compared to AVTO1910 but not significantly different from AVTO1702 (28.5 tons/acre) and AVTO1907 (28.4tons /acre). Although Roma (check) produced the highest total number of fruits per plant (110), it produced the lowest number of marketable fruits per plant (7) compared to all other entries, while the plant height did not show any statistically significant differences between different treatment entries. Two entries with the lowest disease incidence were AVTO1702 and AVTO1954, while Roma was infested with blight and powdery mildew at 27% and 45% respectively. The study recommends the release of three entries viz-a-viz AVTO1954, AVTO1907 and AVTO1702 and similar research in other agroecological zones of Bhutan to identify appropriate varieties in their zones.

Broccoli, cabbage and cauliflower are some of the common vegetables that are grown and traded in Bhutan. It is cultivated in one part of the country and then transported to urban areas of the country for marketing. Poly sacks are commonly used for packing and transporting these vegetables. Plastic crates are recommended and promoted for use in packing and transporting vegetables but there is no study that has been conducted to prove their benefits. The aim of this study was to assess the transportation damage and economic benefit of using plastic crates during the transportation of vegetables compared to that of the poly sack. Broccoli, cabbage and cauliflower were harvested in the late afternoon from Chali Gewog, sorted, packed and transported to the market in Bumthang town in the same evening. At the market, vegetables were assessed for transportation damage and physiological loss of weight was recorded. Broccoli, cabbage and cauliflower packed in poly packs reported transportation damage of 8.75, 8.33 and 12.50 heads against 0.96, 0.44 and 0.41 percent for the plastic crate-packed vegetable samples with significant differences at P≤0.05. Poly-packed samples had significantly higher PLW of 2.02 kg, 2.83 kg and 3.40 kg compared to much lower PLW of 0.21 kg, 0.24 kg and 0.36 kg for broccoli, cabbage and cauliflower, respectively. Among the vegetables packed in poly sacks, transportation damage was significantly higher for cauliflower at 12.5 heads compared to 8.75 and 8.33 heads for broccoli and cabbage. Transportation damage was minimal and not significantly different between the three vegetables for plastic crates sample. Harvesting damage of 0.35 was observed in broccoli while cabbage and cauliflower did not have harvesting damage. Physiological loss of weight was significantly higher in cauliflower for both packaging types. The net return from broccoli, cabbage and cauliflower packed in plastic crates was higher at Nu.27779.4, Nu.8252.48, Nu.31127.4 compared to Nu.25232, Nu.7540 and Nu.26852 for poly sack packages, respectively. It is recommended that use of plastic crates for handling and transportation of broccoli, cabbage and cauliflower be encouraged and promoted among the stakeholders.

Quantitative analysis of velocity profiles at the mid height of channel, at the channel-electrode interface and mid height of electrode thickness is done.  The channel height, thickness and porosity are found to have a substantial effect on the velocity profiles across the battery. It was found that the velocity in the electrode-channel interface is about 3 orders of magnitude lower than velocity in the channels.
How Friendly Diplomatic Relations Promote Bilateral Trade in Digital Services: Empirical Evidence from China's Partnership Diplomacy
Authors: Li Qing , Peng Jiacheng , Han Suxuan , Wu Xiaoqing
Published: March 2023

How to use diplomacy to promote bilateral digital services trade in the context of politicization of trade issues is a key issue for developing countries to seize digital opportunities to develop their productivity. This paper empirically tests the role of partner diplomacy in promoting the development of inter-country trade in services. The study finds that: (1) the scale of bilateral services trade between China and the host country increases by approximately 13% for each partner level increase in diplomatic relations, and this boosting effect remains robust after considering model changes, changes in explanatory variables and endogeneity issues. (2) The mechanism test finds that the promotion effect of partner diplomacy on bilateral services trade is essentially a trade cost-cutting effect, which is achieved in four forms: trade negotiations, high-level visits, treaty signing and platform building.

Authors: Sun Guozhi , Liang Min , Wei Shujuan
Published: March 2023

In the process of economic development, China is trying to smooth the domestic circulation and promote the domestic and international double circulation so as to form a strong domestic market and build a new development pattern. China's socialist market economy is a market-oriented economy, which is essentially a consumer-demand-oriented economy. In its economic development, China has put more emphasis on taking consumption as the driving force of economic development, enhancing the contribution of consumption to economic development, and taking expanding domestic demand as the strategic basis for development. In order to expand domestic demand in the context of double circulation, we should pay attention to coordinating the relationship between accumulation and consumption, expanding domestic demand and opening up, supply structure and demand structure, urban and rural residents' income and social consumption power, give full play to the guiding role of consumption demand, form a positive interaction between consumption demand and economic growth, and promote the healthy development of the socialist market economy.

Does Supplier-base Concentration Influence Corporate Investment Efficiency?
Authors: Wang Binfa , Ge Rui
Published: March 2023

Although suppliers are important stakeholders of firms and intensively interact with the firms, there is limited research on whether and how suppliers influence their customers’ investments. To fill the void in the literature, we examine the relation between supplier-base concentration and corporate investment efficiency. Analyzing a comprehensive sample of Chinese listed firms, we find that when a firm’s supplier-base is more concentrated, its investment efficiency is generally lower. The results hold when we control for various factors that can influence corporate investment efficiency. Furthermore, we show that firms under-invest more when their supplier-base is more concentrated. However, we find no evidence that supplier-base concentration is significantly associated with firms’ over-investments. Overall, our findings suggest that supplier-base concentration impairs firms’ investment efficiency, which manifests in under-investments.
Strength analysis of diesel engine block based on multi-body transient dynamics
Authors: Yu Qian , Wang Guixin , Cao Yilong , Zhao Jiaqi
Published: March 2023

Based on the multi-body transient dynamics calculation method, the strength of a low-speed marine diesel engine block is analyzed. Firstly, UG software is used to simplify the whole machine and obtain the corresponding simplified model. Then, in ANSYS software, the corresponding loads and boundary conditions are applied to each component in the diesel engine model to simulate the normal working process of the diesel engine and calculate the structural strength of the engine block. It is found that the stress on the engine block is not constant, but changes with the rotation of the crankshaft and the explosion of each cylinder. The position of the maximum stress on the engine block appears at the bolt hole on the upper surface of the cylinder block, and is far less than the tensile yield strength of the material. Finally, the fatigue life of the computer block is calculated by importing three elements: stress distribution data, material properties and load spectrum. It is found that the mechanical fatigue life time of the engine block is much longer than the overhaul period of the diesel engine, which can be considered as infinite life.

Authors: Ma Jun , Chen Yanqing
Published: March 2023

The problem of aging has appeared in some countries, and the problem of providing for the aged has become one of the key issues. In recent years, aging has also become a social problem in China, but the current pension model can not meet the diversified and personalized needs of the elderly in China. In this paper, the intelligent community home-based elderly care model has become the forefront of academic research and a new topic of elderly care practice. On this basis, this paper sorts out the research context of the home-based elderly care model in smart communities, and uses Maslow's Hierarchical Needs Theory (MHNT) and Welfare Pluralism Theory (WPT) as research methods to analyze the needs of the elderly and the choice of welfare providers. In addition, this paper uses the method of system dynamics to establish a model to analyze the supply and demand balance of different pension models, and demonstrates the advancement of community home-based pension model. Finally, through the interview and investigation of the staff and managers of the smart community home-based elderly care model in Meilin community, Dongzhi County, Anhui Province, China, this paper summarizes the existing elderly care model in the community, and finds some deficiencies, such as the lack of full-time personnel, the inadequate use of new technologies and the lack of financial support. According to this, the paper puts forward corresponding countermeasures: (1) the problems of personnel can be solved by strengthening the training of service personnel, improving the system of volunteers and community service personnel working together, etc;(2) The problem of technology application can be solved by cooperating with external enterprises or other organizational units in research and development; (3In terms of financial support, it is necessary to broaden the channels of obtaining funds, seek the cooperation of enterprises, and adopt the innovative pension service mode of charging for providing high-end services and using the income for public welfare free basic services to effectively raise funds. Through the above research, the authors can put forward solutions to the pension problems faced by Meilin community, integrate relevant resources, and reduce the social burden.

Authors: Xu Chenguan , Xu Chaoyang , Huo Xianxu , Wang Zhenyu , Wang Kui , Li Ye
Published: March 2023

As a critical field of carbon emission, the clean and low-carbon transformation of power industry is extremely critical to the smooth realization of country’s "dual carbon" goal. From the perspective of the whole power industry chain, the DeBruyn decomposition method was firstly used to determine critical influence factors of carbon emission in the power industry. Next, the response relationship between the influence factors and carbon emission was established. Finally, the peak value and its occurrence time under various scenarios were identified through designing four typical scenarios. The obtained results demonstrated that, under the context of interactive influence among positive driving factors (population size, thermal power generation, industrial structure, GDP), negative driving factors (forest area, energy structure, science and technology investment) and other factors, the carbon-emission amounts of the power industry under baseline scenario were increased continuously; conversely, the peak value of carbon emission under two single carbon reduction policy scenarios (i.e. carbon trading policy and renewable energy quota policy) and their composition scenario would become decrease, being 5.46×109 tons, 5.61×109 tons and 5.16×109 tons, respectively. Correspondingly, the occurrence time of peak value under three scenarios was in 2029, 2029 and 2028, respectively.

Published: March 2023

Classical swine fever is a highly contagious disease of pigs which courses from life-threatening to asymptomatic, depending on the virulence of the virus strain and the immune-competence of the host. The present study was undertaken to investigate the expression of immunologically important genes, viz. IFNα, IFNβ, SLA, SLA-2, SLA-DR, Ii, SLA-DM, CSK and JUN and to ascertain genetic group differences on the basis of humoral immune response. Blood samples were collected from 5 indigenous and 6 crossbred piglets at pre-vaccination and after 28th day of classical swine fever (CSF) vaccination. On 28th day, the competitive Enzyme Linked Immunosorbent Assay (cELISA) revealed poor humoral immune response (E2 antibodies) in indigenous piglets (84.80%) as compared to crossbred piglets (98.33%) in response to CSF vaccination. The expression level of genes was analyzed in three ways, viz. indigenous 28th day post-vaccination (28dpv) versus pre-vaccination, crossbred 28th day post-vaccination versus pre-vaccination and crossbred 28th day post-vaccination versus indigenous 28th day post-vaccination. The study showed that IFNα, IFNβ, SLA, SLA-2, Ii, SLA-DM, CSK and JUN were significantly upregulated in crossbred piglets than indigenous piglets at 28th day post-vaccination. But the SLA-DR was significantly downregulated in CSF vaccinated crossbred over indigenous piglets.

Published: March 2023

The Lactation curve is the relationship between milk yield and lactation length with respect to time. The present study is based on the data on the lactation records of Red Sindhi cows compiled from Central Cattle Breeding Farm (CCBF), Chiplima, Odisha. Five different lactation curve model, viz. Sikka (SIK), Wood (WD), Polynomial (POL), Dijkstra (DIJK), Morant and Gnanasakthy (MG) models were fitted to the weekly test day milk yield (WTDMY) of Red Sindhi dairy cows. The goodness of fit of the models were judged by adjusted coefficient of determination (Adj. R2), root mean square error (RMSE), Akaike’s information criteria (AIC) and Schwartz Bayesian information criterion (SBC). The normality of the residuals was tested by Shapiro –Wilk’s test and autocorrelation was tested by Durbin Watson test. From the analysis of data it is evident that all the models fitted very well the lactation data of Red Sindhi cows with high degree of accuracy (Adj.R2 > 91%) except for the Wood (WD) model. However among all the models, Polynomial model (Dave 1971) was the best fitted model followed by Dijkstra model. Wood model was the least fitted model among all the lactation models. Highest observed peak yield was at sixth week, the same peak period was given by Wood, Polynomial and Dijkstra models. All the estimated peak yields were ranged between 70.14 kg to 75.96 kg.

An experiment was conducted during rabi season of 2013-14 to 2015-16 at Castor-Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar in the north-Gujarat agro-climatic region. The experiment was laid out in split plot design with 5 irrigation scheduling assigned to main plots and 3 hydrogel levels were allocated in sub-plot and replicated thrice. Irrigation scheduled at 0.8 IW/CPE recorded significantly higher growth and yield attributes, viz. plant height, number of primary branches/plant, number of siliquae/plant, number of seeds/siliqua and seed yield (2539 kg/ha) of mustard (Brassica juncea L.). Similarly, oil yield (945.8 kg/ha), monetary returns, production efficiency (19.7 kg/ha/day) and economic efficiency (560.4 Rupees/ha/day) were also recorded higher with the irrigation scheduled at 0.8 IW/CPE over rest of the treatments. Water productivity (8.66kg/ha-mm) was the highest under irrigation scheduled at 0.6 IW/CPE as compared to remaining treatments. Among the hydrogel levels growth parameters, yield attributes, seed yield and oil yield improved with increasing level of hydrogel up to 5.0 kg/ha. The enhanced yield with 5.0 kg/ha hydrogel also resulted in higher production efficiency (15.0 kg/ha/day) and water productivity (8.46 kg/ha-mm).

The enactment of Intellectual Property protection laws globally and involvement of private seed industry in India had become indispensable for protection of IP in agriculture as whole and plant varieties in particular. For protection of plant varieties, the Distinctiveness Uniformity and Stability (DUS) descriptors of various crops (vegetables, field crops, floriculture, horticulture crops, etc.) were developed and notified by the Protection of Plant Varieties and Farmers Rights (PPV and FR) Registry for testing. With increasing awareness of IPR in agriculture, the submission of applications of plant varieties from the notified crops for registration has started for protection under the Registry. Subsequently, public sector (Indian Council of Agricultural Research (ICAR) and Agricultural Universities (AUs)); private sector; and farmers started submission of Extant, New and Essentially Derived Varieties (EDVs) applications in the notified crops. The study period pertaining to years 2007-2015 reveals that public sector has contributed immensely in protecting plant varieties of self-pollinated crops (food, fibre and pulses crops), whereas the private sector’s focus is largely confined towards open-pollinated varieties. Private sector has submitted highest number of ‘EDVs’ of tetraploid cotton. Progress in farmers’ varieties for protection under PPV and FRA reinforces the importance and uniqueness of this sui generis system adopted by India. It is, expected that the prospects of variety and seed development sectors will improve overtime. This trend also opens the scope for the plant breeders to design varietal development programmes for desirable traits in various crop species.

A field experiment was conducted to study the effect of moisture conservation techniques on productivity enhancement in almond (Prunus dulcis Mill) during 2010-11 to 2012-13 at Srinagar, Jammu and Kashmir. Treatment sincluded five water harvesting techniques, viz. half-moon (W1), full-moon (W2), cup and plate (W3), trench (W4) and control (W5) and three mulch materials, viz. plastic mulch (M1), organic mulch (M2) and control (M3) were laid out in factorial randomized block design with three replication. The experimental results revealed that maximum mean trunk cross sectional area (266.82 cm2), nut yield (5.37 kg/tree), productivity efficiency (19.47 g/cm2 TCSA) and soil moisture content (13.48%) were recorded in full moon water harvesting technique. Among mulch material, plastic mulch found better in respect to TCSA (255.59 cm2), nut yield (4.99 kg/tree), productivity efficiency (18.88 g/cm2 TCSA) and soil moisture content (12.86%) compared to other treatments. The combined effect of water harvesting and mulching indicated that maximum TCSA (270.48 cm2), nut yield (5.82 kg/tree), productivity efficiency (20.92 g/cm2 TCSA) and soil moisture (13.98 %) were recorded in full moon water harvesting + plastic mulch in almond cultivar Non Pareil under rainfed conditions of north west Himalayan regions of India.

Published: March 2023

Salinity induced changes in physiological relations and the concomitant effects on plant growth were recorded in four bael (Aegle marmelos Correa) cultivars, viz. NB-5, NB-9, CB-1 and CB-2. Plants raised in normal soil (ECe 1.3 dS/m) were irrigated with tap (ECiw 0.5 dS/m) and saline (ECiw 3 and 6 dS/m) waters. Data were recorded for growth, physiological parameters and mineral nutrition 180 days after imposing the salt treatments. NB-5 outperformed other cultivars under saline conditions by maintaining higher leaf chlorophyll and proline levels, retaining Na+ ions in stem and root tissues and by preferentially accumulating K+ and Ca2+ ions to overcome the toxic effects of Na+. Break down of salt tolerance in other cultivars at 6 dS/m salinity can be explained by build up of Na+ to the toxic levels and an accompanying decrease in leaf and stem K+ concentrations. Based on these findings, bael cultivar NB-5 appears to be suitable for commercial cultivation in salt-affected soils.

A field experiment was conducted during kharif 2016 at College of Post Graduate Studies (CAU-Imphal), Umiam, Meghalaya to study the effect of population proportions of component crops on performance of maize (Zea mays L)+ soybean [Glycine max (L.) Merr.] intercropping. The experiment was laid out in randomized block design with three replications comprised eight treatments (sole maize, sole soybean and six treatments on maize+soybean intercropping with different population proportion of component crops. Treatment 2:2 paired maize+soybean recorded maximum maize equivalent yield (3.91 t/ha) and land equivalent ratio (1.23) which were at par with intercropping treatments 1:1 Additive, 1:1 Replacement, 2:1 Replacement and 2:1 Additive but significantly higher over the sole maize and 2:1 Paired intercropped treatments. However, maximum net return (rupees 23643/ha)and B: C (1.68) ratio were recorded from 1:1 R maize+soybean which were at par with 2:1 Replacement and 2:2 Paired but significantly higher over sole maize and other intercropping treatments. Introduction of soybean as an intercrop in maize left relatively higher amount of soil available N, P, soil microbial biomass carbon (SMBC) and dehydrogenase activity (DHA) in soil after crop harvest as compared to sole maize.Significantly higher soil available N was recorded from the treatment 1:1 Replacement while significantly higher soil available P, SMBC and DHA were recorded from the treatment 2:2 Paired over sole maize, respectively.
Historical Aspects Of Health Campaigns In Brazil: Proposing An Education In Health Sciences Through Popular Education
Authors: Costa Jefferson Silva
Published: March 2023

In Brazil, the embryo of what is known today as "Health Education" appears only in the second half of the 19th century, after the arrival of the Portuguese royal family. Despite this, health campaigns, defined as advertisements that aim to guide the execution of self-care practices, therefore essential instruments of Health Education, appeared only in the early twentieth century, based on a coercive and controlling model. Over the decades, the use of health campaigns as instruments of Health Education has had its objectives, target audience, and performance spaces modified. Thus, the way this type of campaign is run today is the result of a historical process that is intertwined with the health and education models advocated in each period of Brazilian history. Nowadays, a more dialogic and inclusive model of Health Education is advocated, called Popular Education in Health, and it is necessary to apply this model to the instruments that make up the health campaigns. Given this, it became evident the need to reflect on the use, production, and messages conveyed in health campaigns in order to understand the need for this material to actually move towards an Education in Health Sciences through Popular Education.

Published: March 2023

then a global scale, public procurement corresponds to about 12% of a nation's GDP. Sustainable Public Procurement (SPP) includes public purchases that adopt sustainability criteria in the bidding processes. The present study sought to investigate, through an integrative review, what would be the main existing challenges in the public sector that hinder the adoption of SPP practices. The results are aimed at challenges related to the degree of economic development of two countries and, also, for a given level of development. It was observed that the limited knowledge of two actors in purchases, in the absence of leadership and the absence of solid data and monitoring, are considered crucial factors for the improvement of this type of purchase, related to goal 12.7, of objective 12, of the UN 2030 Agenda.
Conflicting senses of the natural physical environment (land) and technology in the Amazon: reviewing the stimulus to rubber plantations in 1900-1915
Authors: Bentes Rosineide da Silva
Published: March 2023

In the Amazon, the promotion of rubber plantations, in the years 1900-1915, the territorial sense of land - soil to be deforested for monoculture - collided with the ecological rubber tree property in which land meant the elastic gum forest. This defined the size and contours of the property. The promoters of the plantations built the "civility" of these in contrast to the "incivility" of the ecological rubber tree property. The Brazilian policy for rubber promoted plantations, but this policy did not avenge them. And although several entrepreneurs have tuned in to it, the vast majority of rubber ists (the owners of rubber companies) opposed monoculture, claiming that it would destroy one of its main capitals: the rubber forest.

Hypenia has been subject to taxonomic variations, from one botanical section to a genus of Hyptidinae and remaining undivided or divided up into seven infrageneric sections. Essential oils (EOs) constituents of Hypenia were described only recently and supported the division of the genus into two taxonomic sections. In this work, the composition of EOs of H. helenoi was analyzed using gas chromatography coupled with quadrupole mass spectrometry (GC/MS). Hydrodistillation of aerial parts led to 45 compounds, with emphasis on sesquiterpene hydrocarbons (78%) such as b-element (27%), germacrene D (20%), (E)-caryophyllene (7%) and bicyclo germacrene (6%). b-Pinene (4%) was the majority among the monoterpenes (10%), suggesting the mevalonate pathway in EO biosynthesis. Minor constituents such as globular, spathulenol, and humulene epoxide II were rarely identified in the family (Lamiaceae), while other constituents were described for the first time in the genus.
