Se presenta el estudio de los taxones faunísticos domésticos recuperados en dos contextos espaciales y estratigráficos documentados en la Estructura 12 del yacimiento de La Cueva Pintada de Gáldar (Gran Canaria, España). Datados entre los siglos XV y XVI d.C., uno es indiscutiblemente anterior a la conquista de la isla y el otro corresponde, con toda probabilidad, a un momento en el que esta ya se ha producido. Cerdos, cabras y ovejas son las únicas especies domésticas consumidas durante todo el siglo XV y principios del siglo XVI. No se documentó la introducción de nuevos animales ni se detectó el uso de herramientas metálicas para el tratamiento carnicero o el consumo. Sin embargo, en el contexto más antiguo de los analizados, previo a la anexión definitiva de la isla, la frecuencia de restos de cerdo (NME=63%) es muy superior a la de caprinos (NME=37%), circunstancia prácticamente inédita en el Archipiélago hasta la fecha. Dicha tendencia parece que se invierte a medida que nos acercamos a finales del siglo XV, periodo de plena ocupación colonial. Lo que permanece inalterable es la mayor proporción de cabras con respecto a las ovejas en cada etapa. Los perfiles de mortalidad a lo largo de la secuencia estudiada sugieren que mientras cabras y ovejas eran consumidas a cualquier edad durante todo el año, aunque preferentemente adultas, el sacrificio de cerdos se centraba en individuos subadultos, con edades comprendidas entre los 12- 25 meses, una vez habían alcanzado su peso óptimo. Este resultado muestra el aprovechamiento diversificado de la cabaña caprina y la gestión especializada en el mantenimiento de la cabaña porcina, pudiendo estar su sacrificio asociado a momentos y espacios en los que la demanda de carne fuera mayor.

Published: November 2018

En esta contribución analizamos conjuntos arqueofaunísticos procedentes de de- pósitos inferidos como enterramientos intencionales de objetos (en pozos y como acumulacio- nes). Éstos corresponden a eventos ocurridos en torno a un recinto central del sitio residencial agropastoril Punta de la Peña 9, en Antofagasta de la Sierra, (provincia de Catamarca), Puna meridional argentina, durante el segundo milenio AP (ca. 1516-929 años cal. AP). Realizamos una caracterización de la fauna de vertebrados e invertebrados desde un punto de vista anató- mico, taxonómico y tafonómico. El análisis de estos elementos, las recurrencias y ausencias e indicadores de estacionalidad, sumados a la presencia de otros objetos incluidos en los depósi- tos, su estructuración y cronología relativa a la historia de uso del recinto, son interpretados a la luz de prácticas y relatos tradicionales de los Andes Centro Sur. Esto nos permite postular la ocurrencia de eventos fundacionales y de instancias de propiciación referidas a la estación seca dentro de los ciclos agropastoriles centro-surandinos.

The more commonly used method for making synthetic zeolite from kaolin is hydrothermal method. This research tested a sol-gel method in processing synthetic zeolit using kaolin as the basic ingrediant. The synthetic zeolite derived from the sol-gel method was then characterized using X-ray Difractometer and Scanning Electron Microscope, which found resulting products zeolite-A, zeolite Y and sodalite. The adsorption ability of the synthetic zeolites was tested using Cu(II) and methylene blue. Functionalization of the synthetic zeolites by 3-(trimetoksisilil)-1-propantiol was done to increase adsorption capacity. Zeolite A modified by 3-(trimetoksisilil)-1-propantiol had the greater capacity to adsorb methylene blue at 30.11 mg/g. The adsorption isotherms of all the synthetic zeolites approached the Langmuir form. The adsorption energy off all synthetic zeolites approached the chemical adsorption.DOI: http://dx.doi.org/10.15408/jkv.v0i0.5144

Published: November 2018

OBJECTIVES:To investigate perspectives of mothers with opioid use disorder regarding breastfeeding and rooming-in during the birth hospitalization and identify facilitators and barriers.METHODS:We conducted in-depth qualitative interviews with 25 mothers with opioid use disorder 1–12 weeks after delivery. Grounded theory analysis was used until thematic saturation was reached. Findings were triangulated, with experts in the field and a subset of informants themselves, to ensure data reliability.RESULTS:Among 25 infant-mother dyads, 36% of infants required pharmacologic treatment, 72% of mothers initiated breastfeeding, and 40% continued until discharge. We identified the following themes: (1) information drives maternal feeding choice; (2) the hospital environment is both a source of support and tension for mothers exerting autonomy in the care of their infants; (3) opioid withdrawal symptoms negatively impact breastfeeding; (4) internal and external stigma negatively impact mothers’ self-efficacy; (5) mothers’ histories of abuse and trauma affect their feeding choice and bonding; (6) mothers’ recovery makes caring for their infants emotionally and logistically challenging; and (7) having an infant is a source of resilience and provides a sense of purpose for mothers on their path of recovery.CONCLUSIONS:Future interventions aimed at increasing breastfeeding and rooming-in during the birth hospitalization should focus on education regarding the benefits of breastfeeding and rooming-in, supporting mothers’ autonomy in caring for their infants, minimizing stigma, and maximizing resilience.

Abstract
As host authority for all hydrocarbon resources in Malaysia, post 2016 transformation, the Malaysian Oil and Gas Regulator (PETRONAS MPM) put in place enhanced guidelines for classifying wells to steer Petroleum Arrangement Contractors (PAC's) to align with PETRONAS MPM Total Well Management Key Performance Indicators (KPI's) and aspirations. The well classification guidelines are key inputs to facilitate improvement by PAC's in enhancement of flowing strings and management of idle wells. Additionally, well classification was used in conjunction with new idle well time-bound guidelines to drive abandonment on idle wells with no remaining economic potential. Subsequent to roll-out of PETRONAS MPM enhanced guidelines for classifying wells and the added focus on well management, positive changes were observed in active string percentage (52% to 57%) and idle well management (~5% improvement in effective idle well restoration). The number of abandonment certificates increased from 20 wells to nearly 300 wells since the issuance of the new guidelines, and these wells are being planned for future abandonment with cost-effective and optimized scheduling at a national level.
Perforate Wash and Cement for Large Casing Sizes

Published: November 2018

Abstract
Perforate, Wash & Cement (PWC) is a method developed over the past few years to remediate cement behind casings, which has been widely applied to the Plugging and Abandoning (P&A) of wells. This technique can also be used to set permanent lateral barriers for slot recovery operations. However, the technique has been mostly applied to smaller casing sizes ranging from 7 – 10 ¾". In the growing slot recovery market across mature fields, the demand is increasing for a reliable and efficient method for achieving shallower lateral barriers, thus facilitating side tracks from bigger casing sizes such as 13 3/8" −13 5/8".
For the technology to be successful there are several components that need to be tailored for the specific casing size and borehole diameter. The optimal Tubing Conveyed Perforating (TCP) system needs to be in place to maximize efficiency for the washing and subsequent cementing operation. In order to reduce risk during the washing and cementing operation, it is critical that a suitable area of the wellbore is chosen for the remediation. This area is chosen based on the operational window for the Cup-type PWC technology where annular condition plays an important role. This paper describes the extensive work that has been performed to plan, execute and verify the placement of a lateral barrier across the 13 5/8" casing on the Valhall G-22 Well in the Norwegian continental shelf as part of the slot recovery program for the field.
The testing of the TCP Gun system resulted in an optimum Exit Hole Diameter (EHD) and geometry tailored to this specific application. An ultrasonic log was run prior to the PWC operation to determine the status of the annulus to be remediated. The optimal parameters for efficient cleaning of the annular space were simulated, and successfully achieved within the narrow Equivalent Circulating Density(ECD) window for the weak permeable zone below the perforated interval. The cement job was performed flawlessly with no losses, utilizing the Pump and Pull method with the Cup-type PWC system. Moreover, the actual job parameters matched very well with the simulations. The internal cement was drilled out and the annular cement was logged using an ultrasonic logging tool. The interpretation of the log showed perfect circumferential cement coverage across the entire remediated interval. With proper planning and optimized design and execution parameters, successful annular remediation can be achieved in large casing geometries using the PWC technique. This allows for more efficient and cost-effective slot recovery and P&A operations.
Laparoscopic versus open distal pancreatectomy (LAPOP), study protocol for a single center, non-blinded randomized controlled trial
Authors: Björnsson Bergthor , Sandström Per , Larsson Anna Lindhoff , Hjalmarsson Claes , Gasslander Thomas 
Published: November 2018

Abstract
Background: Earlier non-randomized studies have suggested that laparoscopic distal pancreatectomy (LDP) is advantageous in comparison to open distal pancreatectomy (ODP) regarding hospital stay, blood loss and recovery. Only one randomized study has been conducted showing reduced time to functional recovery after LDP compared to ODP.
Methods: LAPOP is a prospective randomized, non-blinded, parallel group single center superiority trial. Sixty patients with lesions in the pancreatic body or tail that are found by a multidisciplinary tumor board to need surgical resection will be randomized to LDP or ODP. The primary outcome variable is post-operative hospital stay and secondary outcomes include functional recovery (defined as no need for intravenous medications or fluids as well as ambulatory patient able to perform activities of daily live), perioperative bleeding, complications, need of pain medication and quality of life comparison.
Discussion: The LAPOP trial will test the hypothesis that LDP reduces post-operative hospital stay compared to ODP
Protein Footprinting with Radical Probe Mass Spectrometry- Two Decades of Achievement
Authors: Maleknia Simin D. , Downard Kevin M. 
Published: November 2018

Background:Radical Probe Mass Spectrometry (RP-MS) describes a pioneering methodology in structural biology that enables the study of protein structures, their interactions, and dynamics on fast timescales (down to sub-milliseconds). Hydroxyl radicals (•OH) generated directly from water within aqueous solutions induce the oxidation of reactive, solvent accessible amino acid side chains that are then analyzed by mass spectrometry. Introduced in 1998 at the American Society for Mass Spectrometry annual conference, RP-MS was first published on in 1999.Objective:This review article describes developments and applications of the RP-MS methodology over the past two decades.Methods:The RP-MS method has been variously referred to as synchrotron X-ray radiolysis footprinting, Hydroxyl Radical Protein Footprinting (HRPF), X-ray Footprinting with Mass Spectrometry (XF-MS), Fast Photochemical Oxidation of Proteins (FPOP), oxidative labelling, covalent oxidative labelling, and even the Stability of Proteins from Rates of Oxidation (SPROX).Results:The article describes the utility of hydroxyl radicals as a protein structural probe, the advantages of RP-MS in comparison to other MS-based approaches, its proof of concept using ion mobility mass spectrometry, its application to protein structure, folding, complex and aggregation studies, its extension to study the onset of protein damage, its implementation using a high throughput sample loading approach, and the development of protein docking algorithms to aid with data analysis and visualization.Conclusion:RP-MS represents a powerful new structural approach that can aid in our understanding of the structure and functions of proteins, and the impact of sustained oxidation on proteins in disease pathogenesis.
Body Mass Index Impact on Disease Activity, Clinical and Sonographic Remission Rates in Patients with Rheumatoid Arthritis
Authors: Sapundzhieva Tanya , Karalilova Rositsa , Batalov Anastas 
Published: November 2018

Aim:
To investigate the impact of body mass index (BMI) on clinical disease activity
indices and clinical and sonographic remission rates in patients with rheumatoid arthritis (RA).

Patients and Methods:
Sixty-three patients with RA were categorized according to BMI score into
three groups: normal (BMI<25), overweight (BMI 25-30) and obese (BMI≥30). Thirty-three of
them were treated with conventional synthetic disease-modifying anti-rheumatic drugs
(csDMARDs), and 30 with biologic DMARDs (bDMARDs). Patients underwent clinical and laboratory
assessment and musculoskeletal ultrasound examination (MSUS) at baseline and at 6 months
after initiation of therapy. We evaluated the rate of clinical and sonographic remission (defined as
Power Doppler score (PD) = 0) and its correlation with BMI score.

Results:
In the csDMARDs group, 60% of the normal weight patients reached DAS28 remission;
33.3% of the overweight; and 0% of the obese patients. In the bDMARDs group, the percentage of
remission was as follows: 60% in the normal weight subgroup, 33.3% in the overweight; and
15.8% in the obese. Within the csDMARDs treatment group, two significant correlations were
found: BMI score–DAS 28 at 6th month, rs = .372, p = .033; BMI score–DAS 28 categories, rs =
.447, p = .014. Within the bDMARDs group, three significant correlations were identified: BMI
score–PDUS at sixth month, rs = .506, p =.004; BMI score–DAS 28, rs = .511, p = .004; BMI
score–DAS 28 categories, rs = .592, p = .001. Sonographic remission rates at 6 months were significantly
higher in the normal BMI category in both treatment groups.

Conclusion:
BMI influences the treatment response, clinical disease activity indices and the rates
of clinical and sonographic remission in patients with RA. Obesity and overweight are associated
with lower remission rates regardless of the type of treatment.
