El número actual de Teoría y Práctica de la Arqueología Histórica Latinoamericana está enfocado desde la perspectiva de los estudios de casos puntuales, demarcando tanto las posibilidades que ofrece el espectro de sitios arqueológicos en esta disciplina como las características metodológicas que despliegan sus investigadores. Así, el lector pude aproximarse a la arqueología
de templos, cementerios, fábricas, explotaciones de lobos marinos, establecimientos rurales, antiguos espacios de frontera, patrimonio funerario en una ciudad y situaciones históricas de conflictos locales. ¿Se puede inferir que la naturaleza de los registros se dispersa?. No necesariamente: expresa su versatilidad.

Colloidal solution of boron and phosphorus codoped silicon quantum dots—from material development to applications
Authors: Fujii Minoru , Sugimoto Hiroshi , Kano Shinya 
Published: August 2021

Abstract
A core/shell silicon (Si) quantum dot (QD) composed of a crystalline Si core and an amorphous shell, in which boron (B) and phosphorus (P) are very heavily doped, is developed. Because of the amorphous shell, the B and P codoped Si QDs exhibit significantly different physical and chemical properties from undoped ones. The codoped Si QDs are dispersible in polar solvents such as water and alcohol without organic ligands and exhibit stable luminescence in water. Because of the superior properties, the codoped Si QDs have applications in different fields including photonics, biophotonics, photochemistry and electronics. In this article, we discuss the structure and optical and electrical properties of the codoped core/shell Si QDs and show the application potentials in different fields.

Published: August 2021

The effect of temperature on the dielectric properties of some wood species such as Kadam ( Haldina cordifolia), Teak (Tectona grandis L) and Sal tree (Shorea robusta)) wood were investigated at different frequencies from 100Hz to 1MHz along tangential direction. Dielectric constants and dielectric loss factors were measured at temperatures from 30o C to 120°C with variation of frequency showing increase in dielectric constant and dielectric loss with the increase of temperature. Dielectric properties on wood showed a strong relation dependence on the structures, waterÃ¢â‚¬Âwood relations, frequency and temperature. A significant variation in dielectric parameters was observed with respect to each species. An abrupt increase in dielectric constant was observed when frequency was less than 1 kHz. The variation in activation energy is observed from one species to other.

Human host preference of female Anopheles mosquitoes collected from studenthostels of the Lagos State University (LASU) in south Ã¢â‚¬Â western, Nigeriawas determined. Two hundred and seventy two (272) mosquitoes were collectedindoors out of which 219 (80.5%) female Anopheles were identifiedusing morphological characters. One hundred and thirty five (61.6%) femaleswere collected from male hostels whereas 84 (38.3%) were collected fromfemale hostels ( X2= 11.86 P<0.05). Engorged female Anopheles was identifiedby their swollen abdomens. The blood meals were analyzed using directenzyme linked immunosorbent assay (ELISA) methods . From the male hostels,human blood index (HBI) was low as out of 94 blood meals analyzed,only two (2.1%) fed on human , 2 on rats (2.1%), 4 (4.2%) on goat and fifteen(15.9%) were having mixed blood of rat, goat and human, whereas theremaining 61(64.8%) were not found fed on either of these host. The HBI ofAnopheles Anopheles collected from male and female hostels respectively (X2=8.64 P<0.05.) The result suggested that female students were more attractedto anthropophagic Anopheles, and therefore more vulnerable to acquiremalaria infection.collected from female hostels was significantly higher as 37(63.9%) mosquitoes were found fed on human, with 2 (3.4%) having mixedblood of human , rat and goat. The study indicated HBI of 18% and 67.2%from

Published: August 2021

Epigenetic events are due to altered gene expression without any changes inthe genetic material and characteristic of heritability via cell division. Theimpact of epigenetic control over cancer is one among the thrust area ofresearch in cancer biology. The present study deals about the virtual screeningof plant derived bioactives, directed against the key molecular regulatorsof the epigenetic eventsÃ‚Â viz. DNA methyltransferases (DNMT1, DNMT2 andDNMT3B), Histone acetyltransferase (HAT), Histone deacetylase 8 (HDAC8),Histone H3 lysine 27 methyl transferase (H3K27MT) and Histone H3 specificlysine 4 demethylase (H3K4DM). This computational screening identifies themost efficient binders with respect to individual targets in terms of ligandbinding energy. The structure optimization of the best scored docked conformationswill be helpful to reveal new insights and development of naturalbioactives to combat cancer.

Published: August 2021

Extracts of Echinacea species were used traditionally in North America forthe treatment of infections and wounds, and preparations derived from Echinaceapurpurea â€Âcytotoxic concentrations.The immune modulation is manifest in two ways: as a stimulation of phagocytosisand other functions in various types of immune cells, and as an antiinflammatoryagent in epithelial and other cells infected with proinflammatoryviruses and microbes. Studies of gene expression in infectedand uninfected cells have revealed that Echinacea extracts can bring aboutnumerous changes in expression of cytokine, chemokine, and many otherimmune â€Ârelated genes. Thus Echinacea causes many alterations in signalingpathways involved in control of various immunological functions, resulting incontrol of the invading pathogen and amelioration of associated symptoms.

This survey is an assessment of risks associated with consumption of contaminatedÂ drinking water by lead in the cotton zone of Kerou. Lead (Pb) wasÂ measured by atomic absorption spectrophotometer and risk assessment wasÂ made following a standardized method. The results obtained showed thatÂ 22% (7/18) of studied boreholes have been contaminated by lead. In addition,Â boreholes of Ganbore and Korigourou showed relatively high values ofÂ lead levels: 0.061, 0.098 and 0.604 mg/L compared to the accepted value,that is 0.04 mg/L. Risk assessment revealed that Daily Exposure Dose (DED)of lead due to consumption of drinking water in these three regions are thesame, namely 12.54 Æ’ÃŠg/kg/day for children and 3.85 Æ’ÃŠg/kg/day for adultscompared to the daily allowed dose defined by WHO that is 3.6Æ’ÃŠg/kg/day.Kerou in Benin is a good reference of a site to test the hypothesis of the connectionÂ between groundwater and river contamination with heavy metals(Pb in the present investigation) and the intensity of farming activities andcotton cultivation in the zone.These high values can be attributed to infiltrationÂ of residues of pesticides. Also, they can be attributed to contaminationÂ of groundwater by the Mekrou River containing wastewater rich in organicÂ matter. This contamination and exposure are serious risks for human healthÂ and especially for children and needs serious attentions of public health authoritiesÂ and policy makers.

Authors: Panchal Balaji M. , Kachole Manvendra S. 
Published: August 2021

Chilo partellus is considered to be among the most damaging pests of sorghum crop throughout the world. Insects are reared in the laboratory on artificial diets for various purposes, namely for biological control, host and nonâ€host plant resistance and development of new artificial diets. The growth and development of Sorghum bicolor, C. partellus (Lepidoptera: Pyralidae) on six host plants and non host plants (five plant gum extracts and six tuber extracts PIs) was compared in the laboratory. Insect larval growth was significantly faster on 30% casein with 70% Zea mays in artificial diet. There was a significant variation in larval mortality, malformed pupae andpupal weights. 80% larval mortality was observed in Acacia leucophloea PIs containing diet, and 70 and 60% larval mortality in Ipomoea batatas and Mangifera indica PIâ€containing diet fed, respectively.
A Survey of browse plants used in feeding small ruminants in the Komendaâ€ Edinaâ€Eguafoâ€Abrem district (K.E.E.A) of the Central Region of Ghana
Authors: Agyeman K. , Apori S. O. 
Published: August 2021

A study was carried out to identify species used as fodder by small ruminant farmers in the selected villages in the Komendaâ€Edinaâ€Eguafoâ€Abrem district of the Central Region of Ghana. Livestock farmers in fifteen communities were interviewed using questionnaires to obtain information on the personal background and livestock feeding and management practices. The main aim of the study was first to identify existing browse species and to determine problems associated with the use of those existing browse species. Some problems identified include harboring of insects, causing of abortion as well as causing bloat. The survey showed that Ficus exasperata, Ficus umbellate, Baphia nitida, Griffonia simplifolia, Antiaris africana, Terminalia catappa, Grewia carprinifolia, Pethecellobium dulceand Leucaena leucocephala were the main browse species that were used in the district to feed small ruminants. Other feedstuffs that were used in feeding animals such as Aspillia africana and Manihot esulentus tops (leaves and peels) were also identified. The level of browse usage showed that Ficus exasperata had the highest value of 66.7% and Terminalia catappa had the lowest value of 13.3%. Farmers in the district preferred Ficus exasperata which they perceived to promote the best production response in livestock. Various reasons were assigned for the selection of a particular browse plant. Farmers in the district may have to be helped to cultivate browse plant in order to sustain the availability and usage of browse for livestock feeding due to the rateof destruction of browse (shrubs and trees) resulting from urbanization, use of stem of shrubs and trees for fuelwood and other livelihood activities and desertification arising from human related activities.

Published: August 2021

Based on the fact that the Mediterranean sea is an existing place to the bivalves fan mussels of Pinna nobilis, the aim of this introductory study is to focus on understanding the nature of P.nobilis population density and its structure with an ongoing purpose to encourage future investigation of the subject matter to successfully uncover more ecological models; in order to reach the latter, a field-work took place from 2015 to 2018 in the Algerian west coasts on multiple sites with an end goal of better understanding the dynamics of the species, as well as assessing the effectiveness of protective measures of P.nobilis on the Algerian Western coastlines. The density, population structure and the growth of individuals noted on P.nobilis were examined through scuba diving along with multiple transects on the west coast of Algeria and measurements were executed on different spatial scales in populations occupying different sites; one of, is that of the protected naval area of “Habibas Island” in addition to other unprotected ones. . The results varied and they are as follows: the density of P. nobilis ranged from 0.28 in /m-2 on the transect to 0.08 in /m-2. The measured individuals were certainly a representative of their environment. The size of the P.nobilis did not prove itself to be prominent disturbance in the structure of the associated biota; the latter however showed that it was influenced by different areas. The outcomes of the study state that the recovery of the P. nobilis population on the west coast of Algeria was highlighted; stating the urgent need for setting security and protection of these species located on the Algerian West Coasts.

Published: August 2021

The botanic genera Pistacia are groups around een species of shrubs that belong to the Anacardiaceae family which is believed to have originated in Asian or Mediterranean region. P. len scus is abundant species of the Pistacia genus encountered in the forest region of Ouarsenis mount (Northwest of Algeria), exactly in the na onal park of Thniet El Had in the Wilaya of Tissemsilt in Algeria. In the present study, chemical composi on and an bac- terial ac vi es of essential oil (EO) of P. lentiscus were evaluated. The EO was isolated and analyzed by gas chromatography-mass spectrometry (GC- MS). The minimum inhibitory concentra on (MIC) was determined using 6 strains of Gram-positive and negative bacteria. The antibiogram was made following the gliosis-environment diffusion method and which makes it possible to determinate bacteria’s sensibility to an bio cs. From a exponential culture (18 to 24 hours), a bacterial suspension was prepared and well- homogenized a erwards. The opacity was adjusted equivalent to 0.5 McF (McFarland). Based on the GC-MS analysis, thirty five compounds representing 100 % of the total oil composi on were iden ed. The essen al oils could be explored to test their an microbial activity, especially against some bacteria that cause alimentary intoxications. The results revealed that the essen al oil exhibited strong levels of an bacterial activity against the tested microorganism regarding the MIC values, Salmonella sp was found to be the most sensitive strain (inhibition zone 23cm MIC 1.25%). Based on the findings of the present study, new an bacterial agents could be developed, and the use of P. lentiscus should be promoted in the traditional treatment of ailments.

Published: August 2021

A search for multidrug-resistant bacteria was conducted in 1,143 clinical samples in Morocco from which 244 isolates were tested against 29 different antibiotics. This showed a prevalence of resistant strains of 68.4%. The spectra of resistance ranged from 1 to 21. Ampicillin, Ticarcilin, Amoxicillin, Piperacillin and Ciproflaxin were the most frequently resisted. Eight antibiotics were tested against two selected strains, S. aureus 400037 from conjunctive mucosa and A. baumannii 280291 urine, which showed resistance to concentrations up to 240 µg.ml-1. A. baumannii 280291 also resisted the two bacteriocins nisin A and pediocin PA-1, while S. aureus 400037 showed relative sensitivity to nisin A with a MIC of 125 µg.ml-1 but was insensitive to pediocin PA-1. However, the combined use of antibiotics and bacteriocins showedpotentiating effects of bacteriocins on antibiotics or synergistic effects between the two antimicrobials. Combinations with nisin A resulted for instance in a sensitisation of S. aureus 400037 to penicillin G, amoxicillin, ampicillin, cefaclor and ciprofloxacin with MIC values as low as 0.19; 0.78; 0.31; 3.75 and 0.62 µg.ml-1 respectively. Against A. baumannii 280291, the MIC value of gentamycin decreased from 60 to 3.75 µg.ml-1, in the presence of nisin. Similar results were obtained when antibiotics were combined with pediocin PA-1 and such effects were even stronger when both bacteriocins were used along with antibiotics. The present study shows that pathogenic bacteria that developed high levels of resistance to a wide array of antibiotics can be rendered sensitive to the same antibiotics simply by combining them with bacteriocins.
