Laser scanning is a non-invasive method for collecting and parameterizing 3D data of well reflecting objects. These systems have been used for 3D imaging of plant growth and structure analysis. A prerequisite is that the recorded signals originate from the true plant surface. In this paper we studied the effects of species, leaf chlorophyll content and sensor settings on the suitability and acc...

Among latex-producing plants, mainly the latex of Hevea brasiliensis has been studied in detail so far, while comprehensive comparative studies of latex coagulation mechanisms among the more than 20,000 latex-bearing plant species are lacking. In order to give new insights into the potential variety of coagulation mechanisms, the untreated natural latices of five latex-bearing plants from the f...

It has long been known that there is a sustained electrical potential (voltage) difference between the xylem of many plants and their surrounding soil, but the mechanism behind this voltage has remained controversial. After eliminating any extraneous capacitive or inductive couplings and ground-mediated electric current flows, we have measured sustained differences of 50-200 mV between the xyle...

We consider the inequality $f \geqslant f\star f$ for real integrable functions on $d$ dimensional Euclidean space where $f\star denotes convolution of $f$ with itself. show that all such are non-negative, which is not case same in $L^p$ any $1 < p \leqslant 2$, defined. also solutions satisfy $\int f(x){\rm d}x \tfrac12$. Moreover, if = \tfrac12$, then must decay fairly slowly: |x| \infty$, an...

Las plantas tienen importancia ecológica y social en la arborización de las ciudades. En ciudad Iquitos no se han realizado muchos estudios al respecto. El objetivo del presente estudio fue determinar diversidad composición arbóreas calles centro Iquitos, Loreto, Perú. inventario realizó diez consideraron con tallos ≥ 5 cm diámetro a altura pecho (DAP), muestras fueron herborizadas. Se registra...

Urban parks and gardens are one of the most important pathways for deliberate introduction non-native plant species, some which cause environmental socioeconomic impacts. We conducted a risk assessment on 388 woody species from 46 urban mainland Spain to classify them in lists based their invasion status, being invasive elsewhere, climate matching with area origin, potential negative Only Ficus...

The skin before being tanned has a drawback that is it very easy to be attacked by microorganisms. Thus, necessary develop antimicrobial through the application of nanoparticles. Antibacterial and antifungal activities, contact angle, mechanical properties goat pickle leather after modification with silver nanoparticles methyltrimethoxysilane (MTMS) in situ ex method had been conducted. Silver ...
